Only 40 sand lorries from Malaysia cross to Singapore

New Straits Times 19 Nov 09;

JOHOR BARU: The state Customs Department yesterday revealed the number of lorries carrying sand that ply between Johor and Singapore via the Causeway.

The figures were for lorries passing through the Wisma Kastam cargo checkpoint at Tanjung Puteri here.

The figures showed that 1,000 lorries moved between Johor and Singapore through the checkpoint daily.

It was reported on Tuesday that out of 1,000 lorries going through daily, 500 were carrying sand.

Department director Mhd Subre Ishak said the 500 lorries did not carry sand, but various materials with only a small number carrying silica sand.

"There are only 40 Singapore-bound lorries which carried silica sand on a daily basis," he said.

His clarification was aimed at quashing worries of large exports of sand to the republic, which is an issue of controversy. Local suppliers are alleged to have ignored local demand and preferred to export their sand to Singapore due to the high exchange rate.

Sand also became an issue during the controversial reclamation works done by Singapore at Tuas and Pulau Tokong near Kota Tinggi, which began in December 2002.

Subre said the Customs Department conducted stringent checks on sand-laden lorries at the checkpoint, including taking samples and sending them for tests at the Geology Department.

He said his department also kept tabs on "high-risk" exporters, which were companies with records of Customs offences.

Extra lane at CIQ complex to ease traffic congestion
New Straits Times 18 Nov 09;

JOHOR BARU: Contractor Gerbang Perdana will build an extra lane to ease congestion at the Sultan Iskandar Customs, Immigration and Quarantine (CIQ) complex.

Works Minister Datuk Shaziman Abu Mansor said the extra lane would be a ramp leading to the new Eastern Dispersal Link on the Johor side, and would be completed in a month.

Shaziman said once the new lane was completed, there would be three lanes for cars to enter Johor Baru, after the Customs checkpoint.

The new lane is among several routes, called medium-term routes, that will be completed by the end of next year.

"We have asked Gerbang Perdana to complete the work earlier as all medium-term routes are supposed to be completed in March 2011.

"The work is 47 per cent complete. The medium-term routes cost RM253 million."

On complaints of congestion caused by lorries at the Causeway, Shaziman said the problem should be resolved as the cargo checkpoint for lorries in Tanjung Puteri began operating 24 hours since Sunday.

He said the congestion was caused by Singapore-bound lorries that wait near the Tanjung Puteri cargo checkpoint after clearance by Customs.

"Many lorry drivers wait for the right time to enter Singapore. They usually wait for the operation hours (of businesses) to begin at 9am before proceeding. This is one cause for the congestion," Shaziman said after visiting the CIQ complex and cargo complex for lorries at Tanjung Puteri.

He said 700 lorries travelled from Singapore to Malaysia through the Causeway daily, while the daily number of lorries from Malaysia to Singapore was 1,000. About 500 of the Singapore-bound lorries carry sand.

Shaziman said he would brief the cabinet on Friday on other measures to ease traffic congestion at the CIQ complex.

Among them is a proposal to add another 36 immigration booths to the current 36 at the complex. "PLUS (Projek Lebuhraya Utara-Selatan) Bhd has agreed to this."

Food security a matter of breaking habits

Quality counts, not whether your chicken is from Malaysia or Brazil
Jessica Lim, Straits Times 19 Nov 09;

WITH Apec dominating the news, what occurred on Wednesday last week would have barely registered on most Singaporeans' radar.

To recap: You could not have bought fresh pork here last Wednesday if you had tried.

That strange state of affairs was caused by a hairline crack in a metal tube supplying ammonia to cool the air in the meat chillers in Singapore's sole abattoir.

Operations were halted, and meat from 900 pigs was incinerated in case of contamination. The ruptured pipe was replaced and slaughter resumed the next day. Because fresh pork needs to be sufficiently chilled before sale, no pork was market-ready last Wednesday.

Big deal? Not to many here. My guess is that most Singaporeans either did not notice, or switched their dinner menu. In the grander scheme of things, however, it was a very big deal.

A leaky pipe caused last week's problem. But if one stopped to think about it, there are any number of events that could disrupt Singapore's food supplies.

The World Wide Fund (WWF) for Nature said just that in a report released last week. It said that because of Singapore's dependency on imports - more than 90 per cent of all food consumed here is brought in from abroad - 'any significant damage to crops in neighbouring countries will affect agriculture and food supplies'.

In fact, such events have already occurred. Last month, vegetable wholesaler Gary Ong, 43, imported 20,000kg less cabbage and bak choy from Indonesia after heavy rains there destroyed crops.

Again, however, customers did not notice.

Mr Ong, whose Vat Thoa Vegetables Wholesaler supplies greens to hawkers and supermarkets, simply switched to Chinese sources instead.

This happy state of affairs is the result of Singapore's successful efforts to diversify its food sources. The effort began in 1985, but it picked up steam last year when hikes in fuel and commodity prices led to sharp increases in food prices.

The Agri-Food and Veterinary Authority (AVA) is Singapore's point agency in scouring the ends of the earth for new food sources.

As a result, we now have fish from Namibia, rice from Vietnam and eggs from the United States to complement the usual sources - Indonesia, Thailand and Malaysia, respectively. Diversification, said an AVA spokesman, is a key strategy in ensuring 'food resilience'.

The AVA's efforts have paid dividends. As of March this year, 745 companies from all over the world were accredited to export meat, processed meat and eggs to Singapore. This is up from 218 in 2004.

In 1992, food exports from 14 countries were allowed in Singapore. That number is now 31.

When it comes to processed food, some 2,475 types across 38,662 brands from 155 countries are imported - about twice the number of brands in 2004.

So with so many sources, what is the problem? Well, you, the consumer, actually.

We Singaporeans love our food. Perhaps because of this, we are extremely picky about it, too.

Despite food from many countries being approved for sale here, the reality is that little is brought in.

Rice importer Jimmy Soh, for instance, stopped importing the US grain two years ago because of poor sales.

'Restaurants stopped ordering it from us after a few months, so we stopped bringing it in,' he said. Consumers, he explained, preferred the longer-grain Thai variety.

The restaurant Peach Garden has a similar story to tell. It began importing goose meat from France and Taiwan in 2004, when supplies from China were cut in January that year after bird flu hit the country. The move bombed spectacularly.

Said Peach Garden spokesman Veronica Tan: 'The response was really bad. Customers complained that the meat was tough, old and dry. So we stopped selling it altogether.'

For Ong Joo Joo Food Industries, too, the diversification experiment has not gone well. It battled for two whole years to sell customers on frozen pork, and many are still not convinced.

Therein lies the rub, said the meat importer's managing director, Mr Ting Puong Huat.

'If the consumers don't accept new products, importers might not bring them in,' he said.

At best, this means a smaller basket of goods on the market. At worst, it means importers will not be able to switch sources quickly enough when the need arises, leading to shortages, and, eventually, higher prices.

Of course, food is a matter of taste. Until we are faced with a genuine shortage, we will be loath to change what works for us. But, really, is there such a big difference? Or are we just slaves to habit?

Chef Yadi Musmulyadi of the Changi Village Hotel believes it does not make 'much difference where the food is from if it's all high quality. It is all about habit'.

'If we tell customers the chicken is from Malaysia, some turn their noses up at it. If we say it's from Brazil, they think it tastes better,' he said, adding that if cooked well, the difference is hardly noticeable.

Go to a supermarket, however, and the tables are turned. Customers will instinctively ignore frozen Brazilian chicken and pick the chilled fowl from Malaysia, believing it to be fresher. If that is not habit, I do not know what is.

Last year, when prices went through the roof, Singaporeans had no trouble switching from olive oil to housebrand cooking oil.

Choice, obviously, is a good thing. But what if global warming, a freak weather pattern, some new virus or a hairline crack in a pipe results in disruption?

Solar energy firms in Singapore 'face challenges'

Seris says it needs tech innovations to make it competitive without subsidies
Joyce Hooi, Business Times 19 Nov 09;

SOLAR energy may be deemed the most promising renewable energy in Singapore, but a lack of subsidies has kept costs high, made building owners wary and created challenges for solar energy firms here.

'The challenge in Singapore is that there is no clear incentive scheme. Most people perceive solar energy to be expensive,' said Christophe Inglin, managing director of Phoenix Solar.

While solar module prices have come down 35 per cent over the past 12 months, they remain costly. Installing a solar photovoltaic system for a typical landed residence in Singapore costs $100,000 on average.

'For commercial buildings in Singapore, the payback period is 20 years. In Europe, it's 10 years because of the subsidies,' said Mr Inglin.

European countries, the United States and Australia have already adopted the 'feed-in tariff', an incentive structure that obliges electricity utility companies to buy renewable energy electricity at above-market rates, which will defray the high costs of solar energy installation.

In Queensland, Australia, customers who participate in this scheme are paid 44 cents (S$0.56) per kilowatt hour for surplus electricity fed back into the grid.

In Singapore, commercial building owners need to apply for a licence to sell back excess electricity generated from solar energy, and then only at market rates.

'There should have been a feed-in tariff in place from the beginning. The solar energy industry is a very technology-driven industry that is very suitable for a country like Singapore,' Armin Sandhoevel, chief executive officer of Allianz Climate Solutions, told BT yesterday.

The Solar Energy Research Institute of Singapore (Seris), however, believes in tackling the cost issues inherent in solar energy production.

'We need technological innovations to make solar energy competitive without any subsidies,' said Armin Aberle, deputy chief executive officer of Seris, speaking at the Clean Energy Expo panel discussion yesterday.

Other practical concerns continue to dog a solar energy industry that has yet to mature here.

While landed properties are well-placed to benefit from roof-top solar photovoltaic systems, similar efforts by residents in condominiums and multi-storey buildings have been thwarted by lack of coordination.

'The initiative has to come from the property developers,' said Jason Lee, a sales manager with Phoenix Solar.

The field of renewable energy is also such a novel one that mechanical and engineering consultants here lack familiarity with installation.

On that front, the Energy Market Authority (EMA) has moved to launch a handbook for contractors and laymen on installing solar photovoltaic systems.

In the absence of a clear mandate for solar energy, however, the EMA said yesterday its renewable energy test-bed site on Pulau Ubin will include wind and bio-mass energy along with solar energy. This suggests that Singapore continues to hedge its bets where the choice of renewable energy is concerned.

'There is currently no clear winner, but solar photovoltaic energy is the most promising one in Singapore,' said EMA deputy chief executive David Tan.

Currently, 1MW of solar photovoltaic capacity has been installed in Singapore and another 4MW is planned.

Clean energy pact will help Singapore firms enter Indonesia

Jessica Cheam, Straits Times 19 Nov 09;

SINGAPORE companies involved in the clean energy sector could soon gain easier access to the huge Indonesian market, thanks to a clean energy pact inked yesterday.

The Sustainable Energy Association of Singapore (Seas) inked a Memorandum of Understanding with the Sustainable Energy Association of Indonesia yesterday to collaborate on sustainable, renewable and energy efficiency issues.

Seas chairman Edwin Khew said yesterday that as Singapore's market size was limited, it is crucial for firms to be able to gain access into the bigger, neighbouring markets.

'Indonesia has a lot of potential for clean energy projects and Singapore can help develop this sector by providing a one-stop shop for technology, services, and finance,' he said.

Being home to the largest collection of banks, clean technology funds and green funds in Asia, Singapore can provide equity and debt for Asian clean energy projects, he added.

The former nominated MP noted that the sector is dominated by small and medium-sized enterprises (SMEs) rather than multinationals, and that the only way to bring SMEs together is through forging associations across Asia.

'This is where Singapore can play a regional role,' he said.

The MOU was signed yesterday at the opening of the three-day Clean Energy Expo Asia trade fair and conference, which forms part of the Singapore International Energy Week.

Guest speaker Michael Liebreich, chairman and chief executive of research firm New Energy Finance, said Singapore was well positioned to tap the US$100 billion-worth (S$139 billion) of clean investment money that flowed into Asia each year.

'Singapore can play the same role as London. Singapore is also a financing centre, plus a technology and logistics hub. A lot of that US$100 billion will go through Singapore,' he said.

The gathering momentum of clean energy investment has been made evident by the Asian Development Bank (ADB), which has announced that it is poised to sharply increase lending for clean energy projects in the Asia-Pacific region by 2013.

Its deputy director-general for regional and sustainable development, Woochong Um, told The Straits Times that the bank aims to almost double annual lending for clean energy projects from about US$1.2 billion this year to US$2 billion by 2013.

And it is set to reduce lending to fossil-fuel projects.

The bank may well up its share of clean energy lending from less than half in 2005 to 80 per cent of its total energy lending programme in 2013, he added.

The Seas and ADB are working together to promote clean energy in Asia under a programme called Energy for All (E4All), which aims to provide energy access to 100 million people by 2015 using low carbon technologies.

$10b Bridge Best Option for Linking Java, Sumatra, Says Government

Dion Bisara, Jakarta Globe 18 Nov 09;

The government has decided that a bridge is the most feasible of three options for connecting Java and Sumatra, paving the way for construction of the $10 billion Sunda Strait bridge to proceed, officials said on Tuesday.

The decision removes at least some of the uncertainty over the fate of the bridge, which would connect the country’s two most populous islands.

Last week, Coordinating Minister for the Economy Hatta Rajasa said the government was still considering the tunnel, while Deputy Transportation Minister Bambang Susantono said in September, when he was deputy to the coordinating minister, that improving ferry services might be the answer.

However, Hermanto Dardak, the newly appointed deputy minister of public works, said on Tuesday that it had been decided that the bridge was the solution for linking the islands.

“The Sunda Strait is a 150-meter-deep ocean trench. So considering the potential dangers from earthquakes, the bridge option was selected for safety reasons. It is also better as rail services can be accommodated,” he said. “If we opted for a tunnel, capacity would be severely limited.”

Hermanto said a presidential decree would be issued establishing a committee to oversee a feasibility study.

Marzan Aziz Iskandar, head of the Agency for the Assessment and Application of Technology (BPPT), agreed that a bridge was the best option.

“We are quite familiar with bridge technology, compared with tunnels, with which we have little experience. Indonesia can avail itself of the expertise gained during the building of the Suramadu Bridge [linking Surabaya and Madura] and a bridge in Batam.”

The Banten and Lampung provincial governments, which initiated the Sunda Strait bridge proposal, can now breath a little easier as observers had warned that central government support would be essential if there was to be any realistic prospect of it ever being built.

PT Bangungraha Sejahtera Mulia, a subsidiary of Artha Graha Networks, has already completed a preliminary study on the project’s viability.

The BSM study calls for a 30-kilometer bridge spanning the Sunda Strait between Java and Sumatra. The project would consist of a series of spans carrying a six-lane highway and double-track railway via the islands of Prajurit, Sangiang and Ular.

The longest span is projected to be about three km in length, more than 50 percent longer than the main span of the Akashi-Kaikyo Bridge in Japan, the longest suspension bridge in the world.

Indonesia To Build World's Longest Bridge
Bernama 19 Nov 09;

JAKARTA, Nov 19 (Bernama) -- Indonesia would begin constructing the world's would-be longest bridge in Sunda Strait connecting two main islands of Sumatra and Java in 2014, as an effort to boost infrastructure development in the southeast Asian largest economy.

The 30-km long bridge is expected to boost economy in both islands, particularly in Sumatra island, in which over 80 percent of the country's about 230 million population live, said Public Works Minister Joko Kirmanto said here Thursday.

"The bridge could become a landmark of Indonesia," Antara news agency cited the minister as saying.

Kirmanto said that that Indonesian President Susilo Bambang Yudhoyono had asked him to establish a task force team to analyze the mega project.

"We expect the construction would start in 2014. The President has instructed the public minister to set up a team which will analyze the project within the first 100 days of the cabinet work, " he told reporters after a cabinet meeting at the State Palace here.

"As the technology of bridge has developed, the bridge could be a land mark of Indonesia," said Kirmanto.

The project could cost over 100,000 trillion rupiah (some US$10.6 billion), according to a pre-feasibility study.

"The team would count the real cost of the project and to determine the source of the funds. It may be from the state budget or private sector, or the combination of them," he said.

In January 2010, the team would start working, said Kirmanto.

According to the pre-feasibility study, the bridge would have the longest span in the world, about 220 meters.

President Yudhoyono, who was re-elected for his second term on July 8, has promised to boost development of infrastructure during his second term to reach an annual economic growth of at least 7 percent at the end of his term in 2014.

In June, Indonesia completed the building of the longest bridge in Southeast Asia with about 5 kilometers in length, connecting East Java and its island of Madura.

Experts had predicted that the sea ports in the strait could not facilitate the growing economic activities in the two islands within ten years.

Power project `poses threat' to Bali starling

Desy Nurhayati, The Jakarta Post 18 Nov 09;

The construction of high-voltage power lines connecting the East Java and Bali grids may pose a further threat to the critically endangered Bali starling, an ornithologist warned Tuesday.

The power lines, which are expected to boost the island's electricity supply by 1,000 megawatts (MW), could pass over the West Bali National Park, a natural habitat for the bird.

Bogor Institute of Agriculture (IPB) ornithologist Jarwadi B. Hernowo said the inevitable opening up of the park due to the project could lead to increased poaching of the starlings.

"There's no guarantee that there won't be any poaching of the birds or destruction of their habitat," said Jarwadi, who recently did a study on the local starling population.

"It's a security problem that threatens the species."

The Bali Crossing project will transmit power from the Paiton plant in East Java to Bali, which currently has a supply of only 500 MW.

"The shortest way to connect the two islands is through Lampu Merah, Labuan Lalang, Kotal and Brumbun, most of which is part of the national park," Jarwadi said. "So the project will certainly affect the habitat."

However, state electricity monopoly PT PLN has made assurances the project will not pass over the national park area, located on the western tip of Bali.

PLN Bali general manager Arifuddin Nurdin said transmission towers to support the cables would be installed along the periphery of the national park, without actually crossing into the protected area.

He said the company had discussed the plan with the provincial administration to ensure minimum impact on the park.

PLN will suspend the cables around 45 meters above the tallest trees, Arifuddin said.

Should the power lines pass over the national park, Jarwadi said, supervision by forest rangers should be tightened to prevent poaching of wildlife and destruction of conservation areas.

An estimated 80 Bali starlings live in the park. The population began dwindling in the 1990s due to rampant poaching of the indigenous species, which fetched up to Rp 40 million a bird at that time.

Conservationists have conducted numerous reintroduction programs to boost the starling population.

Park head Bambang Darmaja called for a win-win solution to the electricity issue.

"We must ensure the species are not threatened, and at the same time the project must go ahead to supply more power to Bali," he said. "We support the project, so long as we can find a win-win solution."

The Forestry Ministry has not yet issued a permit for the project.

A joint team of park officials, scientists, academics and government officials will be set up to evaluate the impact of the project on the park and its wildlife.

Bali Starling Threatened by Poaching, Development
Made Arya Kencana, Jakarta Globe 18 Nov 09;

Kuta, Bali. The future of Bali’s critically endangered avian emblem, the Bali starling, is increasingly heading the way of the extinct Bali tiger due to continued poaching and an electricity development project that threatens the bird’s dwindling habitat.

Jarwadi B Hernowo, an ornithologist from the Bogor Institute of Agriculture (IPB), said his research had revealed that the reduction of the West Bali National Park — established in Jembrana district largely to protect the bird, known locally as jalak Bali — had increased access to the protected coastal forests, leading to increased poaching.

Speaking at an international workshop in Kuta on Tuesday about improving management systems at the park, Jarwadi said his research from June 2008 through October 2009 showed that there were just 60 to 80 of the birds left in the wild. In 1978, by comparison, 550 Bali starlings were recorded in the wild.

He also believed the entire population — with the exception of at least three hatchlings — comprised birds released into the wild over the past three years.

The other major threat to the population, Jarwadi said, was the Java-Bali interconnected power transmission network, also called the Bali Crossing project.

He said the shortest distance between Java and Bali was from the northwest, through the West Bali National Park. If transmission lines were to be constructed throughout the park, he said the habitat would be under even greater threat.

Jarwadi said the Bali Crossing project could lead to new road networks in or around the park, opening up access to the forests.

“Perhaps [such plans] will not affect the Bali starling’s food and water supply, but its safety should also be considered. Remember that poaching poses the most significant threat to the birds,” he said.

Jawardi gave as examples several national projects that had infringed on wildlife habitats across the country, including Ladya Galaska, a road project in Gunung Leuser National Park in North Sumatra and Aceh, and the construction of a road that dissects the Baluran National Park in East Java.

Arifuddin Nurdin, general manager for state power utility PT Perusahaan Listrik Negara in Bali, said the power grid for the Bali Crossing would be situated on the periphery of the park, without infringing on the forest.

Bidding for the project is currently underway with at least three foreign firms expressing interest, he said, adding that the project was expected to be operational by 2013.

Freedom sought for bile-farm bears in Vietnam

Vietnam News 18 Nov 09;

HA NOI — Animals Asia Foundation (AAF) has received more than 7,000 letters from around the world urging the Vietnamese Government to confiscate bears being held illegally on bile farms in the popular tourist spot of Ha Long Bay, in the northern province of Quang Ninh.

The letter-writing campaign was launched by the AAF after trying for two years to convince the authorities to confiscate 79 bears (endangered Asiatic black bears, also known as moon bears) that are not registered and have no microchips – legal requirements in Viet Nam.

A police raid in October confirmed there were 24 illegal bears held on one farm at Dai Yen just outside Ha Long city.

More than 7,000 people including politicians from the UK, Australia and Europe, and internationally best-selling authors had written letters to the Vietnamese Prime Minister, according to Jill Robinson, founder and CEO of AAF.

"This sends a very strong message that the world is watching and people will not remain silent while endangered moon bears are treated so cruelly and driven to the point of extinction," Robinson said. "All we are asking is that the government implement its own laws and protect this majestic species for future generations."

Bear bile farming was made illegal in Viet Nam in 1992, but farmers are allowed to keep the bears to display to tourists. In an attempt to protect the few bears remaining in the wild, the authorities together with the World Society for the Protection of Animals – micro-chipped the 4,000 bears on farms. The 79 bears in question, including the 24 targeted in the recent raid, have no microchips, which means they were probably illegally caught in the wild.

"We put our faith in the government, and have built a world-class bear rescue centre to accommodate these bears. The government’s failure to act is tarnishing Viet Nam’s image around the world and not fulfilling its international commitment in protecting endangered wildlife," said Tuan Bendixsen, Animals Asia’s Viet Nam director.

Viet Nam’s Environmental Police and the local Ha Long Police caught employees of the Dai Yen farm extracting and selling bear bile to Korean tourists last month.

Bile extraction equipment and more than 200 vials containing freshly extracted bile were confiscated, yet still no one has been charged. According to the police report, each month, 30 to 40 tour groups visit the farm to buy bear bile.

Animals Asia investigators first alerted the authorities to the illegal activities at farms in the Ha Long Bay area in 2007. Undercover film footage and photos proving bile was still being extracted from bears and sold to tourists was passed over to the Government. This prompted an earlier raid on farms in the area, with 80 bears being identified as being held illegally.

So far, just one bear has been removed to the Viet Nam Bear Rescue Centre. Animals Asia and other non-governmental organisations – Education for Nature Viet Nam, Free the Bears Fund Inc, Wildlife at Risks, and the World Society for the Protection of Animals – have formed the Viet Nam NGO Bear Taskforce.

Bear bile is used in traditional medicine for a range of "heat-related" ailments such as eye and liver disease. In November 2005, Animals Asia signed an agreement with the Vietnamese Government to rescue 200 bears and care for them at the Viet Nam Moon Bear Rescue Centre in Tam Dao National Park.

To date, the centre hosts 28 bears confiscated by the government and currently has the capacity to receive 100 more bears rescued from bear farms.

At least two deputies of the Viet Nam’s National Assembly, Prof Nguyen Lan Dung and Nguyen Dinh Xuan, are planning to call for the confiscation of the 24 bears during the assembly’s November 17-19 session.

The 7,000-plus letters, which will be delivered to the Prime Minister’s office soon, include those from internationally acclaimed authors Bryce Courtenay and Bradley Trevor Greive. — VNS

Rare crocs found hiding in plain sight in Cambodia

Michael Casey, Associated Press Yahoo News 18 Nov 09;

BANGKOK – Conservationists searching for one of the world's most endangered crocodile species say they have found dozens of the reptiles lounging in plain sight — at a wildlife rescue center in Cambodia.

DNA taken from 69 crocodiles housed in the moats of the Phnom Tamao Wildlife Rescue Center showed nearly 50 percent were Siamese crocodiles, which until recently were believed to have become extinct in the wild, researchers said Wednesday.

"For the first time in Cambodia, we have a captive population of animals that we know 100 percent are purebred Siamese crocodiles," said Adam Starr, who manages the Cambodian Crocodile Conservation Program, a joint effort between the government and Fauna & Flora International. The Washington, D.C.-based conservation group Wildlife Alliance also took part.

Once common throughout Southeast Asia, the Siamese crocodile or crocodylus Siamensis is locally extinct in 99 percent of the areas it once roamed and is listed as critically endangered by the International Union for Conservation of Nature. Much of the wild population was wiped out by habitat loss and poaching.

Those left in the wild — thought to be less than 250, with nearly all in Cambodia and the rest in Indonesia and Vietnam — face the new threat of hydropower dams being built in two of their three known habitats in the country.

Starr said the discovery of the captive population would give conservationists new options for breeding and reintroducing the crocodiles into the wild, most likely in places not affected by the dams. He said up to 60 crocodiles a year could be released into areas where they once thrived.

DNA analysis, which was done at Thailand's Kasetsart University, is necessary because it is virtually impossible to tell the difference between Siamese crocodiles and the hybrid crocodile species that are also housed at the center.

Nhek Ratanapech, director of the wildlife center, said he was surprised to learn that so many of the crocodiles turned out to be pure Siamese.

"Before we conducted the DNA testing, we thought perhaps only three or four of them in the zoo were Siamese crocodiles," he said.

Siamese crocs are said to be a bit smaller at just under 10 feet (3.5 meters) than hybrids, and their snouts are shorter and wider.

Reef Conservation Strategy Backfires

Richard Harris, NPR 18 Nov 09;

Aid organizations concerned about overfishing on tropical reefs often try to encourage fishermen out of their boats by offering them better-paying jobs on shore. But this strategy actually may make matters worse.

Fish Or Coconuts

Take, for example, the story of Kiribati, an island nation in the central Pacific. Kiribati (pronounced KIR-a-bahs) has a simple economy. People either catch fish, or they pick coconuts from their trees and produce coconut oil. Sheila Walsh, a postdoctoral researcher at Brown University, says most people do a bit of each.

The Kiribati government was concerned about overfishing. So it came up with a plan: It would subsidize the coconut oil industry.

"The thought was that by paying people more to do coconut agriculture, they would do less fishing," says Walsh. "And this would fulfill two goals: One, they would reduce overfishing; and two, people would be better off. They would have higher incomes."

Walsh wanted to know whether this plan was working, and the government invited her to study the issue. So, as part of her graduate work at the Scripps Institution of Oceanography, she flew to Kiribati to interview fishermen.

Coconut Subsidies Cause More Fishing

"And it turned out that, actually, the result of paying people more to do coconut agriculture was to increase fishing," she says. In fact, fishing increased by a startling 33 percent. The reef fish population dropped by an estimated 17 percent, putting the whole ecosystem at risk.

"It was a bit of a surprise, and we were wondering: What's going on here?"

The answer was simplicity itself. Walsh's study concludes that people earned more money making coconut oil, which meant they could work less to support themselves. And they spent their new leisure time fishing.

"It hit us like a bumper sticker saying — a bad day fishing is better than a good day working. And that's sort of the story here," Walsh says.

Fishing For Pleasure

It turns out she had stumbled into a universal truth about fishing. Fishermen aren't just in it for the money. Anthropologist Richard Pollnac of the University of Rhode Island says, just think of those snazzy sport-fishing excursions.

"People pay big money to go sports-fishing," he notes. There aren't very many occupations that people will actually pay money to do in their leisure time, he says.

So fishing as an occupation provides psychic benefits, as well as money. Pollnac argues that not just individuals but whole cultures get hooked on the thrill of being out on the water, and the gamble of coming back with either a boatload or empty-handed.

"This type of an occupation selects for a certain type of personality, and that kind of personality will not be happy in many other occupations other than fishing," Pollnac says. As a result, attempts to get fishermen to do something else — even something that pays better — often end in failure.

"There have been projects where they had vessel buyback programs, and almost 50 percent of the fishermen used that money to buy another boat to do another type of fishing, and in some cases get right back into fishing," Pollnac says.

The track record for international projects is poorly studied, which makes Walsh's research notable. Pollnac says he can't point to any great successes.

"A great deal of the international development money, I would argue, is wasted."

This problem is not lost on Craig Leisher at the Nature Conservancy. His organization does spend money to help fishermen seek other livelihoods. But does it keep them out of their boats?

"Well, no," he says. "It doesn't work to get them off the water. Rarely."

New Jobs Should Be On Water

He says the Nature Conservancy creates non-fishing jobs, but only as a tactic to help during a transition. For example, fishermen may need a temporary source of income when a new no-fishing zone is established. Fishermen lose their fishing income for a while — until fish populations in the no-fishing zone grow large enough to provide a new source of fish in the surrounding waters.

"What we have found with our research is that a lot of alternative income activities are not successful in the long term, so we look for activities that can benefit communities in the near term, just two or three years," Leisher says.

Which brings us back to the island nation of Kiribati. Walsh says she's trying to help the government figure out how to fix the problem of overfishing, which they'd accidentally made worse. Maybe, she says, the government can create new jobs out on the water by hiring the fishermen to patrol newly created nature preserves.

Madagascar's lemurs in danger from political turmoil and 'timber mafia'

• Extinction fear as agencies halt aid to Madagascar
• Loggers and poachers reverse conservation gains
David Smith, guardian.co.uk 17 Nov 09;

The lemur, a furry primate that symbolises Madagascar's unique biodiversity, is under renewed threat from a "timber mafia" pillaging the island's forests for profit.

Environmentalists warn that a political crisis in the impoverished country is reversing conservation gains of recent years and putting "hundreds if not thousands" of species, many not yet identified, at risk of extinction.

Madagascar, which has been isolated from landmasses for more than 160m years, is the world's fourth largest island and a "conservation hotspot" with thousands of exotic species found only here. These include nearly 100 species of lemur, six of which are deemed critically endangered.

Decades of logging, mining and slash-and-burn farming have destroyed 90% of Madagascar's forests, though the rate has slowed in the past two decades.

The former president, Marc Ravalomanana, was praised for putting 6m hectares under protection and backing eco-friendly community projects and sustainable farming. But Ravalomanana was ousted in March in a violent coup that led to a breakdown of law and order and a "gold rush" of armed loggers and poachers. International sanctions have caused the suspension of environmental programmes and could hit 45 national parks that are 90% dependent on overseas aid.

Lemurs' natural habitat is under threat from the accelerating deforestation. In addition, the endangered animals are being hunted for bushmeat, either to be eaten by drought-afflicted local populations or sold as a roasted delicacy in city restaurants.

Dr Hantanirina Rasamimanana, a researcher and teacher at Antananarivo University, said: "Deforestation is always a problem, but in these past five months bushmeat is also very dangerous. People are desperate because of the lack of rain."

She added: "Here in Madagascar, when there is a political change, everything is burning. It's always like that. They burn, they cut, they destroy, they steal. "If they don't stop, I am afraid that some species will become extinct." Conservationists say that armed gangs are exploiting the security vacuum to pillage rosewood and ebony from supposedly protected forests on behalf of a so-called "timber mafia".

This year an estimated $100m worth of hardwood has been cut down and sold, mostly to China to be turned into furniture.

The government, which levies a 40% export tax, is accused of not only failing to stop the trade but actively encouraging it.

It issued an order last month authorising the export of raw and semi-processed hardwood. This supposedly related to trees already felled in cyclones, but environmental activists say it has only provided an incentive for more illegal logging.

Niall O'Connor, head of the World Wide Fund for Nature's Indian Ocean regional office, said: "This is the legalisation of illegally cut timber. The government stands to make a lot from the tax levied on this timber. The current crisis is setting back the good impacts made in conservation in the past 15 to 20 years."

About half of Madagascar's national budget, and 70% of investment spending, comes from outside assistance. But after the coup by city mayor and former DJ Andry Rajoelina, most international donors and lending agencies suspended or cancelled non-humanitarian assistance until a constitutional government is elected.

The WWF has been forced to suspend several projects. O'Connor said: "The impact of not having funding is probably greater than the political crisis. You start to lose the confidence of the communities. If the World Bank doesn't fund Madagascar national parks, they will run out of money very quickly."

Madagascar's $390m (£230m) a year tourism industry, of which eco-tourism is the backbone, is down to just 40% of its normal level due to this year's instability.

O'Connor warned that Madagascar's priceless natural laboratory was in jeopardy. "We have the potential for losing hundreds if not thousands of species. There are still new species being discovered: plants, birds, chameleons, lemurs, tortoises that we might not yet know about, that could be on the brink of extinction."

Mislabelling drives skate to brink of extinction

Yahoo News 18 Nov 09;

PARIS (AFP) – Due to an 83-year-old error of classification, a species of European skate could become the first marine fish driven to extinction by commercial fishing, according to a study released on Wednesday.

In the 19th century, scientists identified two separate species of the once-widespread European skate, the flapper skate (Dipturus intermedia) and the blue skate (Dipturus flossada).

But an influential study in 1926 argued the two species were in fact one, which prompted a new name, Dipturus batis.

Since then, trawling has massively depleted all types of European skate stocks, with France accounting for more than 60 percent of landings.

New research, led by Samuel Inglesias of France's Museum of Natural History and using molecular analysis of DNA, proves once and for all that the initial classification was correct.

As a result of the overfishing, the flapper skate is on the fast track to being wiped out, the paper says.

"[Without] immediate and incisive action, the species may be in an irreversible decline towards extinction," Inglesias said in a statement.

The blue skate is in sharp decline but is still a viable species, the study says.

Iglesias said the discovery highlights the need "for a huge reassessment of population for the different Dipturus species in European waters."

The study was published in the journal Aquatic Conservation: Marine and Freshwater Ecosystems.

Skate may be fished to extinction
Victoria Gill, BBC News 18 Nov 09;

A species of skate could become the first marine fish driven to extinction by commercial fishing, say scientists.

A study reveals that an error in the classification of the species has meant researchers have failed to see just how close to the brink it is.

The French team reports its findings in the journal Aquatic Conservation.

Marine biologist Nicholas Dulvy from Simon Fraser University in Canada says the skate is now "the most precarious marine species on Earth".

The team's genetic studies have revealed that what is referred to as the common skate is actually two clearly distinct species - the flapper skate (Dipturus intermedia) and the blue skate (Dipturus flossada).

The fish were originally categorised separately, but an influential study in 1926 recognised only one valid species - Dipturus batis . This classification has been unchallenged since.

The 80-year error has ensured that fisheries have not been catching what they thought, explained Dr Dulvy, who is also co-chair of the World Conservation Union's (IUCN) shark specialist group.

The result has been that catches of the smaller, more resilient blue skate has entirely masked the decline of the flapper skate.

Disappearing fast

The research team, led by Samuel Iglesias from the Marine Biology Station in Concarneau on the west coast of France, paints a very bleak picture for the future of the flapper skate.

Dr Iglesias and his team spent over a year working with French fisheries and taking DNA samples from the skate that was caught.

His findings finally revealed that the larger D. intermedia species was indeed in serious decline.

Dr Iglesias said: "The threat of extinction for European Dipturus together with mislabelling in fishery statistics highlight the need for a huge reassessment of population for the different Dipturus species in European waters.

"Without revision and recognition of its distinct status the world's largest skate, D. intermedia , could soon be rendered extinct."

Dr Dulvy added: "As far as we can tell, [humans have] not yet driven anything fully to extinction by over-fishing."

He and many other marine scientists are now very concerned that this skate species will be the first.

Paying More for Flights Eases Guilt, Not Emissions

Elisabeth Rosenthal, The New York Times 17 Nov 09;

In 2002 Responsible Travel became one of the first travel companies to offer customers the option of buying so-called carbon offsets to counter the planet-warming emissions generated by their airline flights.

But last month Responsible Travel canceled the program, saying that while it might help travelers feel virtuous, it was not helping to reduce global emissions. In fact, company officials said, it might even encourage some people to travel or consume more.

“The carbon offset has become this magic pill, a kind of get-out-of-jail-free card,” Justin Francis, the managing director of Responsible Travel, one of the world’s largest green travel companies to embrace environmental sustainability, said in an interview. “It’s seductive to the consumer who says, ‘It’s $4 and I’m carbon-neutral, so I can fly all I want.’ ”

Offsets, he argues, are distracting people from making more significant behavioral changes, like flying less.

In theory, the purchase of carbon offsets is supposed to cancel out the emissions generated by activities like flying or heating office buildings by directing money to programs that reduce emissions elsewhere, like tree-planting in Africa or a hydropower project in Brazil. An airline passenger might volunteer to pay $5 to $40 to offset his flight, with the price linked to distance.

Offsets have played a growing role in the greening of travel because carbon dioxide emissions from airplanes are growing so quickly and there is currently no technological fix that would drastically lower them.

In the United States, dozens of hotels and airlines have embraced such programs in the last year or two. United Airlines became the latest American airline to offer one this summer. Globally, offset programs have grown into a multimillion-dollar industry.

But it has proved difficult to monitor or quantify the emissions-reducing potential of the thousands of green projects financed by customers’ payments, and there are no industrywide standards.

Responsible Travel is not the only organization that has changed its mind about the usefulness of offsets: Yahoo and the United States House of Representatives both ended trial offset-purchase programs this year, concluding that the money was better spent on improving their buildings’ energy efficiency.

Some of the world’s leading experts on the emissions issue have reviewed and rejected purchasing offsets for air travel.

“We’re always looking at it, but so far I’ve decided not to do it,” said Paul Dickinson, chief executive of the Carbon Disclosure Project, a vast nonprofit consortium of companies that have pledged to report and reduce their emissions. For one thing, he said, offsetting the emissions of a flight from London to New York would probably require an extra fee of $200 to $300, far above what any airline is now charging.

And some experts say that emissions from airline travel are simply so large that it may be impossible to offset them.

“Buying offsets is a nice idea, just like giving money to a soup kitchen is a nice idea, but that doesn’t end world hunger,” said Anja Kollmuss, a staff scientist for the Stockholm Environment Institute who is based at a branch at Tufts University.

“Buying offsets won’t solve the problem because flying around the way we do is simply unsustainable,” said Ms. Kollmuss, who has researched airline offsets.

A recent study in Britain concluded that one flight from London to Los Angeles produced more carbon dioxide per person than the average British commuter produces in a year by traveling by train, subway or car.

Airlines defend offsets, even while acknowledging that some projects have not lived up to their promises. For example, mango trees that were planted in India to offset a concert tour by the band Coldplay were found to have died a few years later.

EasyJet, one of Europe’s largest low-cost airlines, did not offer offsets until 2007 — late for a European carrier — because it was trying to figure out how to ensure the money went to the right places, said Oliver Aust, a spokesman.

It now gives passengers the option of offsetting their flight emissions by investing directly in projects that have been approved by a United Nations certification program for reducing emissions.

EasyJet, which was founded in 1995 but has vastly expanded its fleet since 2003, also uses only the newest and most fuel-efficient jets, flies full planes and packs in extra rows of seats, making its estimated emissions per passenger 28 percent lower than more established carriers on the same routes. Some airlines are experimenting with innovations that may someday reduce emissions, like using fuels made with algae rather than crude oil.

Passenger offsets purport to cancel out carbon dioxide emissions ton for ton through investments in green projects. But critics say there is no transparency about how companies measure whether that happens.

For example, many airlines offer investments in tree-planting projects because trees absorb carbon dioxide. But experts say it takes decades for trees to start fully absorbing the gas, making them a questionable offset for airplanes, which emit carbon dioxide. Ms. Kollmuss said the quality of offsets depended on the project. “But if it’s very cheap, it does raise red flags,” she said.

For Mr. Francis of Responsible Travel, the final straw came when he noticed that carbon offsets were being offered by private jet companies and helicopter tour operators, which generate very high emissions per passenger. “The message was, ‘Don’t worry, you can offset the emissions,’ ” he said. “But you don’t really need to see Sydney from the air, do you? And you can travel in a commercial airliner.”

Mr. Francis said he was not advocating an end to flying — Responsible Travel offers tours to Jordan, the Galapagos Islands and China, among other far-flung destinations — but simply more reflection on the environmental impact of such journeys.

Responsible Travel had bought its offsets through one of the best-known offset companies, ClimateCare, which was purchased last year by JP Morgan.

While acknowledging that improved, universal standards for personal airline offsets are needed, Richard Folland, a climate change and energy adviser to JP Morgan, said the offset concept had played an important role in helping to direct money to otherwise unaffordable environmental projects in poorer countries.

“The primary goal is to reduce emissions, but offsets are helpful” in managing the costs, he said, adding, “There has to be a balance struck.”

Mr. Dickinson of the nonprofit Carbon Disclosure Project said that rather than buying offsets he had sharply scaled back on flying and was instead taking trains or conducting meetings by phone or teleconference. He said that if he owned an airline, he would now be diversifying into other modes of transport.

Referring to the recent purchase of a railroad by the investor Warren Buffett, he said, “What does it tell you that the world’s most successful investor is investing in trains?”

U.S. residents fight for the right to hang laundry

Jon Hurdle, Yahoo News 18 Nov 09;

PERKASIE, Pennsylvania (Reuters) - Carin Froehlich pegs her laundry to three clotheslines strung between trees outside her 18th-century farmhouse, knowing that her actions annoy local officials who have asked her to stop.

Froehlich is among the growing number of people across America fighting for the right to dry their laundry outside against a rising tide of housing associations who oppose the practice despite its energy-saving green appeal.

Although there are no formal laws in this southeast Pennsylvania town against drying laundry outside, a town official called Froehlich to ask her to stop drying clothes in the sun. And she received two anonymous notes from neighbors saying they did not want to see her underwear flapping about.

"They said it made the place look like trailer trash," she said, in her yard across the street from a row of neat, suburban houses. "They said they didn't want to look at my 'unmentionables.'"

Froehlich says she hangs her underwear inside. The effervescent 54-year-old is one of a growing number of Americans demanding the right to dry laundry on clotheslines despite local rules and a culture that frowns on it.

Their interests are represented by Project Laundry List, a group that argues people can save money and reduce carbon emissions by not using their electric or gas dryers, according to the group's executive director, Alexander Lee.

Widespread adoption of clotheslines could significantly reduce U.S. energy consumption, argued Lee, who said dryer use accounts for about 6 percent of U.S. residential electricity use.

Florida, Utah, Maine, Vermont, Colorado, and Hawaii have passed laws restricting the rights of local authorities to stop residents using clotheslines. Another five states are considering similar measures, said Lee, 35, a former lawyer who quit to run the non-profit group.

'RIGHT TO HANG'

His principal opponents are the housing associations such as condominiums and townhouse communities that are home to an estimated 60 million Americans, or about 20 percent of the population. About half of those organizations have 'no hanging' rules, Lee said, and enforce them with fines.

Carl Weiner, a lawyer for about 50 homeowners associations in suburban Philadelphia, said the no-hanging rules are usually included by the communities' developers along with regulations such as a ban on sheds or commercial vehicles.

The no-hanging rules are an aesthetic issue, Weiner said.

"The consensus in most communities is that people don't want to see everybody else's laundry."

He said opposition to clotheslines may ease as more people understand it can save energy and reduce greenhouse gases.

"There is more awareness of impact on the environment," he said. "I would not be surprised to see people questioning these restrictions."

For Froehlich, the "right to hang" is the embodiment of the American tradition of freedom.

"If my husband has a right to have guns in the house, I have a right to hang laundry," said Froehlich, who is writing a book on the subject.

Besides, it saves money. Line-drying laundry for a family of five saves $83 a month in electric bills, she said.

Kevin Firth, who owns a two-bedroom condominium in a Dublin, Pennsylvania housing association, said he was fined $100 by the association for putting up a clothesline in a common area.

"It made me angry and upset," said Firth, a 27-year-old carpenter. "I like having the laundry drying in the sun. It's something I have always done since I was a little kid."

South Sulawesi can be Malaysia's new rice bowl, says PM

New Straits Times 19 Nov 09;

MALAYSIA has identified South Sulawesi as the country's new rice bowl area where it hopes to tap this Indonesian province's resources and availability of land.

Prime Minister Datuk Seri Najib Razak said the government was looking at ways to work with Indonesia on this to boost Malaysia's food security and as a response to the offer made by Indonesian President Susilo Bambang Yudhoyono during his visit recently.

He said South Sulawesi Governor Syahrul Yasin Limpo would visit Malaysia soon to discuss a possible collaboration.

Najib said the government was considering either of two ways to carry out the plan.

One would be through contract farming where Malaysia would use the output by padi farmers there.

The other, he said, would be for the country to develop a new area in South Sulawesi as a major padi-planting area.

Najib said South Sulawesi, which has 670,000 head of cattle, would be the likely place for Malaysia to advance its cattle-farming sector.

"It is our intention to advance our cooperation in the agriculture field as this is related to food security.

"South Sulawesi has a huge potential for this agriculture development plan," he said before departing for Kuala Lumpur at the end of his day-visit here to celebrate the 689th anniversary of the Gowa (ancient Bugis government) administration.

He was accompanied by his wife Datin Seri Rosmah Mansor and Science, Technology and Innovation Minister Datuk Seri Dr Maximus Ongkili.

During the visit, Najib witnessed the signing of three memoranda of understanding between three agencies under the ministry with Hasanuddin University.

The MoUs, for advancements in research and technology, were signed by Mimos, Sirim and Technology Park Malaysia.

During his visit in May, Najib had stressed the importance of Ma-laysia and Indonesia remaining "best friends" regardless the circumstances as their geo-political position made them key to the strength of Asean and east Asia.

Najib and his entourage were the guests of honour at the anniversary celebrations.

He is a celebrated figure in South Sulawesi because of his Ma-kassar-Bugis lineage which can be traced back to the 11th descendent of the local historical figure and hero, the late Sultan Hasanuddin of Gowa.


Addressing a crowd of 5,000 people, Najib described his third visit to Gowa as the return of the "Gowa son" to his ancestors' land.

During his visit in 2005, he was bestowed the title of Mappadulung Daeng Mattimung Karaeng Sanrobone.

Najib said: "This is my history and I am proud of it.

"History has separated us with vast oceans and land, but it cannot separate us in our blood ties, common culture, religion and spirit.

"These are commonalities that serve to make our relationship stronger."

Farmers Face Challenges of Climate Change in Indonesia

Emmy Fitri Jakarta Globe 18 Nov 09;

Farmer Kamsari Turahim, from Santing, Indramayu in West Java, said he could no longer rely on the traditional patterns of rice cultivation because the rain was now much less predictable and the dry seasons lasted longer than ever.

For Kamsari, the old ways of working, where farmers planted their seedlings in mid-November and harvested the crop after about 115 days, are no longer the norm.

Over the last three years, Kamsari said, farmers in his village have seen crops fail because downpours occurred in the middle of the rice season and the rainwater soaked the young plants, devastating the farmers’ hope for a decent return on their seasonal Rp 3 million ($320) investment.

“For three seasons we’ve been forced to harvest earlier than normal, which means we’ve been getting a poor quality of rice. Our income has decreased by more than 50 percent,” he said.

In an effort to be better able to predict the changing weather, the farmers are combining their own knowledge and skills with modern technology.

The farmers came up with a simple method to measure rainwater volume. They took some used tin cans, each the size of an average bucket, nailed them to wooden rods and placed them in the middle of their paddy fields.

“The cans have to be placed in the open, with no trees or other structures nearby,” Kamsari said of his humble invention, which he affectionately calls “teknologi kaleng,” or “tin-can technology.”

By using the cans, farmers can more accurately keep track of rain patterns, which gives them early warning signs of possible flooding.

The Netherlands government has also chipped in, supplying the Indramayu farmers with sensors to measure soil humidity.

The farmers started using the sensors in early October, placing them in 50 locations around the paddy fields, covering a total area of 200 square meters.

“Getting the right measurements for the weather, soil humidity and the rainwater volume gives us a better idea of the best time to begin planting,” Kamsari said.

The World Bank, in a 2007 report titled “Indonesia and Climate Change: Current Status and Policies,” said that the country is vulnerable to climate change, which impacts mainly through prolonged droughts and unseasonal heavy downpours and floods.

The report said that global warming could increase temperatures and shorten yet intensify the rainy season.

These conditions, according to the report, could lead to changes in water supply and soil moisture, which would negatively impact agriculture and therefore food security. Climate change is also likely to reduce soil fertility by 2 percent to 8 percent, resulting in fluctuating rice yields, it said.

Global warming will also cause sea levels to rise, the report said, inundating productive coastal zones and reducing farming in these communities.

Be a Free-Range Chicken

The government, according to Gatot Irianto, the head of research and development at the Agriculture Ministry, has anticipated the impacts of climate change in the agricultural sector by, in the case of rice crops, preparing rice species better able to resist abnormal weather patterns.

The ministry has introduced at least three species of paddy that can survive at least a week of flooding. “Ideally the paddy should be able to tolerate more than a week as it sometimes takes weeks for the water to recede,” Gatot said.

But most important, he said, farmers must have a “healthy” attitude toward changes that are often beyond their control. He praised the efforts of the Indramayu farmers who are trying to cope with the shifting conditions by using their simple invention.

“Don’t be a broiler chicken, be an ayam kampung [free-range chicken],” he said, explaining that ayam kampung are fighters and survivors. “Broiler chickens, on the other hand, are handfed and find it hard to adjust to new environments.”

Gatot said that compared to farmers in Africa, Indonesian farmers were lucky. He cited the 900 millimeters of rain Indonesia received each year, “enough water to irrigate the rice fields, unlike Tunisia, which only gets 300 millimeters per year.”

He was speaking at a recent workshop on “people and adaptation to climate change,” which was jointly organized by the Civil Society Forum for Climate Justice and Oxfam.

One of the problems with climate change, Gatot said, is that it can’t be generalized because its impacts are unique in each region. Farmers in regions that get more rain than before need to plant rice that is resistant to floods, while in regions that experience longer dry spells than in the past, rainwater catchments have to be constructed.

“We can’t use the same theories on weather and planting that our ancestors used because things are changing,” he said. “It’s better to rely on technologies, if there are any, or other innovations, both big and small.”

Though farmers have been urged to leave behind farming traditions that date back centuries, Gatot said his office was trying to put together a database of best practices from “local geniuses,” which may be able to be replicated in other areas.

As an example, he cited the “subak,” or Balinese traditional irrigation system.

“The Balinese irrigation system is a good example,” Gatot said. “It is integrated with their social and cultural systems.”

Despite the challenges, Gatot remains optimistic, saying that if urbanites continue eating rice three times a day, “farmers can still work and still hope.”

“I have long believed that one thing is certain about climate change — everything becomes uncertain. And it is us who need to adjust to the new conditions.”

25 years after Live Aid, Ethiopia tries to cover up a new famine

Francis Elliott, The Times 18 Nov 09;

It wasn’t famine that killed Jamal Ali’s mother. She died in a cholera outbreak that swept through their Ethiopian village when at last the rains came. Twenty-five years later Jamal, now a parent himself, is lining up for handouts in a food distribution centre in Harbu, Amhara, His prematurely aged face, hollow with hunger, creases further when asked about this unwelcome return. “It is a very bitter feeling. No one likes this begging. I am ashamed,” he said.

Up a steep, dusty track from Harbu to Chorisa village the tiny, duncoloured terraced fields bear witness to the third poor harvest in a row. This village is supposed to be an aid showpiece but even here fields of failed cereal crops are being turned over to lean-looking cattle.

A villager strips an ear of the cereal crop tef and cups the inedible seed in her hand for a moment before casting into a relentlessly sky. It’s not that the rains didn’t come, she said — they came just at the wrong time. The field was supposed to yield 500 kilograms of cash crop; now it might just save a few cows from starvation.

The UN warns that 6.2 million Ethiopians will need some sort of food aid in the coming months. The Government also seems highly sensitive to the idea that it needs help. Meles Zenawi, the Prime Minister, would rather the world took notice of his position representing Africa in the climate change negotiations next month than his country’s never-ending dependency on food aid.

In Addis Ababa Ethiopian and Western officials voice disapproval of doom-laden reports that fail to acknowledge the progress being made, or the differences in scale between the famine of 1984, which killed a million people, and the situation today.

In private they acknowledge that Mr Meles and his Government are deliberately frustrating and delaying official assessments of the scale of the country’s humanitarian needs and blocking access to some areas where the situation is worst.

The latest UN estimate, to be released this Friday, is due to revise its figure upwards to nine million for those who will need help. Arguing that the definition of those in need is too broad — it includes those who are in a position to sell assets to buy food — the Government wants to change the way the figures are calculated to reduce that figure to 5 million.

Donor countries and the UN fear that counting only the truly desperate is a ploy that risks understating the true scale of the crisis. There are also allegations that food aid is being withheld from the regime’s opponents.

Criticism of Ethiopia has been muted by its success in improving local healthcare and expanding education, alongside its strategic importance in the fight against Islamic extremism in the Horn of Africa. Britain, which gives the country £200 million a year, and is Ethiopia’s second-largest bilateral donor, is stepping up the pressure on what was once regarded as its showpiece partner in Africa, amid growing concerns about what could happen in the coming months.

“The Government has just got to embrace the crisis and not be frightened of the statistics,” Gareth Thomas, a minister with the Department for International Development, said yesterday. “It is different from 1984 but there’s still huge need. There’s got to be a recognition that if we are going to stop children from being malnourished and keep people alive we have got to have accurate information and we’ve got to have it in a timely manner.”

Speaking before a meeting with Mr Meles, Mr Thomas said that he also intended to raise credible reports that aid was being withheld from opponents, but insisted he was satisfied that British aid was getting through. His main message, however, was that the Government had not yet grasped the urgent need for reform. The population, about 35 million in 1984, is now about 80 million and will have doubled again by 2050. At the same time, according to some estimates, most Ethiopian agriculture is still less productive than that of medieval England.

Mr Meles blames climate change for the erratic rainfall that has led to three successive poor harvests. The state’s ownership of land and its failure to provide seeds and fertiliser is at least as a big a factor, according to observers.

Similarly, the Government has overseen the building of an impressive road network — but in the absence of a thriving private sector and a more liberalised economy the traffic, other than convoys of aid vehicles, is light.

Two million Ethiopians a year are moving into cities as pressure on the land and education increase, a movement that threatens to overwhelm the state’s efforts to provide housing and jobs.

More than half of Britain’s annual aid budget of £117 million goes on helping to fund work schemes that keep 7.5 million Ethiopians out of the food distribution centres. With less than 5 per cent of the population becoming fully self-reliant in most areas each year, the dependency on foreign aid threatens to increase not diminish.

Four ways to feed the world

Debora MacKenzie, New Scientist 18 Nov 09;

IT IS humanity's oldest enemy. Despite all our science, a sixth of people in the developing world are chronically hungry. At a summit in Rome this week, world leaders reaffirmed a pledge to end hunger "at the earliest possible date".

The UN Food and Agriculture Organization (FAO) wanted them to promise to end hunger by 2025, but the delegates declined. They said instead that they would keep trying to meet their previous goal: to halve chronic hunger from 20 per cent of people in developing countries to 10 per cent by 2015 (see graph). But can they? Based on their performance so far, the FAO considers it "unlikely".

That, agricultural experts tell New Scientist, is because governments have broken their promises and slashed aid budgets for agriculture. The hungry poor fell to 16 per cent in 2007, mainly thanks to Asia's economic boom, but recession and soaring food prices pushed it back to 17 per cent in 2008.

"Ending hunger by 2025 is not realistic," says Joachim von Braun of IFPRI, a food-policy institute in Washington DC. "Halving it might be, but it requires sustained action."

It gets worse: global population is set to grow to 9.1 billion by 2050, while global warming will have a serious impact on farming. What can be done?

The FAO says feeding 9 billion people will require a near-doubling in food production. All nations will have to take part, but attention will be focused on poor countries, where there is most room for improvement and where better farming will give poor farmers income to buy food. The FAO says farming investment in poor countries must grow from $142 billion per year to $209 billion.

Agricultural research must also increase. The Consultative Group on International Agricultural Research (CGIAR) - the international, mainly government-funded labs that perform farm research for poor countries - says agricultural R&D spending for developing countries needs to grow from $5.1 billion to $16.4 billion per year by 2025. Its researchers say that in theory, given funds, they can boost agriculture enough to double food production, although global warming may make this impossible. These are their top priorities.
1 Hold on to water

The UN Food and Agriculture Organization says irrigated areas must expand by 11 per cent by 2025, yet the ancient aquifers that feed much of the world's food production are running dry.

Johan Rockström of the Swedish Resilience Centre in Stockholm says we need to rethink water. "Blue" water, which flows in streams, is the usual basis for farm planning yet accounts for just 5 to 15 per cent of the water flowing through farming systems. The rest, "green" water, is either lost through run-off or evaporation or passes usefully through crops. There are several ways to capture more of this green water in crops, including soil-covering mulches, terraces, and underground tanks filled by the run-off from tropical downpours. In parts of Kenya and China such tanks can get a crop through the dry spell that frequently follows a downpour.

Mapping the potential for combining all of these approaches shows that the largest untapped potential to improve water productivity is in the savannahs, says Rockström. This is sometimes counter-intuitive, he adds. "Dry Namibia and Botswana have more than enough green water to feed themselves."
2 Stop ploughing

For 1000 years, farmers have turned over the top layer of soil to bury and kill weed seeds. This is expensive, damages soils and releases greenhouse gases.

Most maize and soya growers in the Americas have abandoned the plough for "no-till" farming: they merely scratch furrows in the ground to plant their seed and handle weeds with herbicides and herbicide-resistant genetically modified crops.

But farmers do not need those if they smother weeds with organic residue such as straw, and rotate crops to frustrate pests, says Bram Govaerts of the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico, a CGIAR lab. This is known as conservation agriculture, and besides conserving soil, nutrients and energy, it cuts water loss. Govaerts has been managing experimental plots in Mexico using these methods, and finds that conservation agriculture can yield as much as traditional agriculture in good years, and even more during drought.
3 Go back to basics

Creating high-yielding seeds is only worthwhile if farmers have access to them, and can sell their produce for a profit. "There are varieties of maize that resist climate stress or disease, but how do you get them to farmers?" asks Prabhu Pingali, deputy head of agriculture at the Bill and Melinda Gates Foundation.

Nerica rice is a case in point. This dryland variety was bred in the 1990s by CGIAR scientists who crossed Asian rice with an African species. Nerica competes better with weeds than other varieties, yields more and contains more protein. But few African farmers have heard of it.

Government services that taught farmers new techniques were dismantled during the debt crisis of the 1980s, says Papa Seck, head of the CGIAR's African Rice Center in Cotonou, Benin. "We need them back."

Even if they have access to better seed varieties, African farmers often don't invest in boosting production because they don't have access to markets and therefore cannot sell their extra crops for a profit. And sold or not, crops are often poorly stored and lost to rot: half the bananas grown in Kenya are lost each year, says Peter Hartmann of IITA, CGIAR's tropical agriculture lab in Ibadan, Nigeria. He says Africa would not need imported food aid if it could use all the crops it produces.

You have to look at the whole food system to boost production, says Hartmann. For instance, IITA bred higher-yielding, disease-resistant cassava and helped set up factories to grind the crop into flour; but then discovered uptake was limited because there was limited transport: cassava grows in southern Nigeria, the trucking industry is in the north. After publicity brought truckers in, production grew from 35 million to 45 million tonnes, on less land, from 2004 to 2007.
4 Boost yields

Mark Rosegrant of the International Food Policy Research Institute (IFPRI) calculates that crops that will yield 25 per cent more food would boost African food production more than doubling irrigation would. It might also be easier. "We have tremendous options to enhance yields," says Hans Braun, head of wheat at the International Maize and Wheat Improvement Center.

Last week the world's wheat scientists launched a consortium to raise wheat yield by genetically re-engineering the crop's photosynthesis, no less. "It is inefficient compared with some plants," says Braun. "Improvements are feasible, and will dramatically increase water efficiency, heat tolerance and yield." They plan to equip wheat with more efficient variants of the key photosynthetic enzyme rubisco, and with suites of genes to convert it from the C3 photosynthetic system to the C4 system found in maize, which fixes more carbon per unit of light. Meanwhile, CGIAR's International Rice Research Institute in the Philippines is developing C4 rice.

Braun says the key is money. The yields of new varieties of maize are climbing twice as fast as yields of rice and wheat. This is because maize is bred mainly by private companies, which invest $1.5 billion a year in it. Wheat and rice breeding, by contrast, is done mostly in government labs. Wheat gets only about $350 million a year. Apart from Chinese hybrid rice varieties, rice yields have been stagnant for years.

60% of Philippines population vulnerable to tsunamis

Estrella Torres, Business Mirror 18 Nov 09;

THE Philippines needs to relocate more than half of the people living in coastal areas as they face tsunamis and disasters linked to climate change, according to a marine biologist.

Former environment secretary Angel Alcala, a marine biologist, who delivered the keynote address of the launching of the United Nations State of World Population on Wednesday said the Philippines has four tsunami areas where the “Earth’s lithospheric plates are [constantly] interacting.”

He said the tsunami-prone areas include south Negros Island; the Cotabato Trench, where 7,000 people were killed in the tsunami in 1976; the Philippine Deep; and the Manila Trench, which starts from the west side of Mindoro Island.

“At least 60 percent of the country’s population live in coastal areas, and they are the most vulnerable to storm surges, strong winds, heavy rainfall and tsunamis,” Alcala said in a press briefing at the launch of the UN State of World Population Report, titled “Facing a Changing World: Women, Population and Climate.”

He said strong typhoons similar to Ketsana and Parma (local names Ondoy and Pepeng) could again hit the country, and a larger part of the population would be affected if the people living in coastal areas were not relocated.

Alcala said the Philippines is also the most vulnerable to facing disasters among the countries in the coral triangle, particularly because more than half of the nation’s population live on the coasts.

The coral triangle refers to the waters off Indonesia, Malaysia, Papua New Guinea, Solomon Islands, the Philippines and Timor Leste.

He also said the impact of disasters related to climate change will also be more destructive as many subdivisions and housing projects are sitting in unstable reclaimed lands.

Slower population growth to help environment: UN study

Richard Ingham Yahoo News 18 Nov 09;

PARIS (AFP) – Braking the rise in Earth's population would be a major help in the fight against global warming, according to an unprecedented UN report published on Wednesday that draws a link between demographic pressure and climate change.

"Slower population growth... would help build social resilience to climate change's impacts and would contribute to a reduction of greenhouse-gas emissions in the future," the UN Population Fund (UNFPA) says.

Its 104-page document emphasises that population policies be driven by support for women, access to family planning, reproductive health and other voluntary measures.

"It really is the first time that a United Nations agency has looked hard at the connections between population and climate change," lead researcher Bob Engelman, vice president for programmes at the green group Worldwatch Institute, told AFP.

"People are at the root of the problem and at the solution of it, and empowerment of women is the key."

The report, the 2009 State of World Population, paints a grim tableau of the peril of climate change and the likely impact on humans, in terms of floods, drought, storms and homelessness.

But it notably puts distance between a decades-long tradition in the UN arena whereby population growth and its part in environmental destruction were rarely -- if ever -- evoked.

"Fear of appearing supportive of population control has until recently held back any mention of 'population' in the climate debate," the document admits.

Things, though, are starting to change. More than three dozen developing countries have already included population issues in national plans on climate, it says.

Negotiators, including the European Union (EU), have tentatively suggested that the question be considered in talks, designed to culminate in Copenhagen next month, for a 192-nation post-2012 global climate pact.

Today, the world's population stands at around 6.8 billion. By mid-century, it will range between 7.959 billion to 10.461 billion, with a mid-estimate of 9.15 billion, according to UN calculations.

The difference between eight billion and nine billion is between one and two billion tonnes of carbon per year, according to research cited in the report.

That would be comparable to savings in emissions by 2050 if all new buildings were constructed to the highest energy-efficiency standards and if two million one-gigawatt wind turbines were built to replace today's coal-fired power plants.

"[P]opulation growth is among the factors influencing total emissions in industrialised as well as developing countries," it says.

"Each person in a population will consume food and require housing, and ideally most will take advantage of transportation, which consumes energy, and may use fuel to heat homes and have access to electricity."

Mitigating population rise would have a double benefit, it says.

It firstly reduces greenhouse-gas output, especially if the decline occurs in developed countries, whose per-capita emissions are up to 10 times those of poor countries.

And it also helps countries -- especially poor nations with high population growth -- adapt to the impacts of climate change.

"The growth of population can contribute to freshwater scarcity or degradation of cropland, which may in turn exacerbate the impacts of climate change," says the report. "So too can climate change make it more difficult for governments to alleviate poverty and achieve the Millennium Development Goals."

The report says taking demographics into account can help national policies and the quest for a UN climate agreement.

Women are not only more vulnerable than men to the effects of climate change but also hold the key to helping resolve it through fertility control and involvement in the economy, it adds.

Thus helping women will entail access to reproductive health care, education and gender equality.

UN: Fight climate change with free condoms
Maria Cheng, Associated Press Yahoo News 18 Nov 09;

LONDON – The battle against global warming could be helped if the world slowed population growth by making free condoms and family planning advice more widely available, the U.N. Population Fund said Wednesday.

The agency did not recommend countries set limits on how many children people should have, but said: "Women with access to reproductive health services ... have lower fertility rates that contribute to slower growth in greenhouse gas emissions."

"As the growth of population, economies and consumption outpaces the Earth's capacity to adjust, climate change could become much more extreme and conceivably catastrophic," the report said.

The world's population will likely rise from the current 6.7 billion to 9.2 billion in 2050, with most of the growth in less developed regions, according to a 2006 report by the United Nations.

The U.N. Population Fund acknowledged it had no proof of the effect that population control would have on climate change. "The linkages between population and climate change are in most cases complex and indirect," the report said.

It also said that while there is no doubt that "people cause climate change," the developing world has been responsible for a much smaller share of world's greenhouse gas emissions than developed countries.

Still, Thoraya Ahmed Obaid, the U.N. Population Fund's executive director, told a news conference in London on Wednesday that global warming could be catastrophic for people in poor countries, particularly women.

"We have now reached a point where humanity is approaching the brink of disaster," she said.

In three weeks, a global conference will be held in Copenhagen aimed at reaching a deal to replace the 1997 Kyoto Protocol, which required 37 industrial countries to cut heat-trapping greenhouse gas emissions.

On Wednesday, one analyst criticized the U.N. Population Fund's pronouncements as alarmist and unhelpful.

"It requires a major leap of imagination to believe that free condoms will cool down the climate," said Caroline Boin, a policy analyst at International Policy Network, a London-based think tank.

She also questioned earlier efforts by the agency to control the world's population.

In its 1987 report, the U.N. Population Fund warned that once the global population hit 5 billion, the world "could degenerate into disaster." At the time, the agency said "more vigorous attempts to slow undue population growth" were needed in many countries.

According to Boin, "Numerous environmental indicators show that with development and economic growth we are able to preserve more natural habitats. There is no causal relationship between population density and poverty."

In this month's Bulletin, the World Health Organization's journal, two experts also warned about the dangers of linking fertility to climate change.

"Using the need to reduce climate change as a justification for curbing the fertility of individual women at best provokes controversy and at worst provides a mandate to suppress individual freedoms," wrote WHO's Diarmid Campbell-Lendrum and Manjula Lusti-Narasimhan.

Dutch approve project to store CO2 underground

Yahoo News 18 Nov 09;

THE HAGUE (AFP) – The Dutch government said Wednesday it had approved the experimental below-ground storage of excess CO2 to curb damaging emissions, dismissing concerns of residents who live on top of the project.

The test project would kick off from 2012 with CO2 stored in a spent natural gas field with a capacity of 0.8 megatonnes underneath the eastern town of Barendrecht, a government statement said.

"After the CO2 has been stored there for several years, an evaluation will be done," it said.

"Only if no problems have arisen by then will authorisation be given for storage at a second, larger field... with a capacity of nine megatonnes."

Shell plans to capture and store at Barendrecht CO2 emitted from its refinery at the Port of Rotterdam. The project, the total cost of which was not revealed, will be subsidised by the Dutch state to the tune of 30 million euros.

The municipality of Barendrecht, provincial authorities and inhabitants, concerned about the risk of explosion and earth movement, are opposed to the project and vowed Wednesday to resist it.

"The municipality does not accept the decision," said a statement from Barendrecht, saying it hoped the move would be overturned by parliament, failing which the town would go to court.

"We will not cooperate with the issuing of plans and permits," said the statement, accusing the government of "being blind to the concerns of inhabitants of Barendrecht", thousands of whom live on top of the gas fields.

The government said "the capture and storage of CO2 is essential as a transitional technology to limit climate damage."

The Netherlands, it said, had a storage capacity of some 800 megatonnes under land and another 800 megatonnes under sea.

"This will allow us to store 40 megatonnes per year for 40 years, the equivalent of 20 percent of our current annual CO2 emissions."

Seas Grow Less Effective at Absorbing Emissions

Sindya N. Bhanoo, The New York Times 18 Nov 09;

The Earth’s oceans, which have absorbed carbon dioxide from fuel emissions since the dawn of the industrial era, have recently grown less efficient at sopping it up, new research suggests.

Emissions from the burning of fossil fuels began soaring in the 1950s, and oceans largely kept up, scientists say. But the growth in the intake rate has slowed since the 1980s, and markedly so since 2000, the authors of a study write in a report in Thursday’s issue of Nature.

The research suggests that the seas cannot indefinitely be considered a reliable “carbon sink” as humans generate heat-trapping gases linked to global warming.

The slowdown in the rise of the absorption rate resulted from a gradual change in the oceans’ chemistry, the study found. “The more carbon dioxide the ocean absorbs, the more acidic it becomes and the less carbon dioxide it can absorb,” said the study’s lead author, Samar Khatiwala, a research scientist at the Lamont-Doherty Earth Observatory of Columbia University and a professor at the Georgia Institute of Technology.

“It’s a small change in absolute terms,” Dr. Khatiwala said. “What I think is fairly clear and important in the long term is the trend toward lower values, which implies that more of the emissions will remain in the atmosphere.”

To calculate the slowdown, Dr. Khatiwala and his collaborators created a mathematical model using tens of thousands of measurements of seawater collected over the past 20 years, including temperature, salinity and the presence of manufactured chlorofluorocarbons as a reflection of industrial activity.

They then worked backward with the data to create a formula that estimated the accumulation of human-generated carbon dioxide in the oceans from 1765, the opening of the industrial era, to 2008.

Even as human-generated emissions of carbon dioxide increase, the oceans’ uptake rate growth appears to have dropped by 10 percent from 2000 to 2007, Dr. Khatiwala said.

The last major research effort to measure industrial carbon uptake in the oceans was published in a 2004 Science study led by Christopher Sabine.

His methodology was different but arrived at similar conclusions.

Dr. Sabine used carbon dioxide measurements taken by more than 100 cruise ships to come up with a single figure: the oceans’ total industrial carbon uptake until 1994.

Dr. Khatiwala’s approach provides estimates of ocean carbon storage for every year from 1765 to 2008.

“Sabine’s estimate was like a single fuzzy snapshot,” Dr. Khatiwala said. “We’ve gone from that to having a relatively short movie of what happened from the start of the industrial era.”

Dr. Sabine said he agreed with the analogy, pointing out that his estimate for uptake up to 1994 was very close to Dr. Khatiwala’s for that period.

“Even though the techniques are completely different, they are in consensus at the one point that we can compare them,” Dr. Sabine said.

Yet much work remains to be done to confirm the results and to expand upon them, Dr. Khatiwala said.

Ocean Losing Its Appetite for Carbon
Christine Dell'Amore, National Geographic News 18 Nov 09;

The world's oceans, which normally gobble up carbon dioxide, are getting stuffed to the gills, according to the most thorough study to date of human-made carbon in the seas.

Between 2000 and 2007, as emissions of the potent greenhouse gas carbon dioxide skyrocketed, the amount of human-made carbon absorbed by the oceans fell from 27 to 24 percent.

In terms of ocean processes, "that's a pretty large drop, and the trend is pretty clear: The ocean can't keep up with [human-made carbon]," said study leader Samar Khatiwala, an oceanographer at Columbia University's Lamont-Doherty Earth Observatory.

Khatiwala is careful to point out that the total uptake of carbon is not declining—the rate is just not growing as fast as it used to.

But if the oceans continue to be overwhelmed by carbon, more of the gas will remain in the already warming atmosphere, the authors say.

"Ultimately the ocean is what's controlling what's going on here," said Chris Sabine, a supervisory oceanographer at NOAA's Pacific Marine Environmental Laboratory in Seattle, Washington, who was not involved in the research.

"It's a big deal that it's becoming less efficient in taking up CO2."

Working Backward

Carbon dioxide easily dissolves in seawater, so the oceans act as gigantic carbon sinks.

The blue part of our planet currently stockpiles about 150 billion tons of carbon. In 2008 the oceans sucked up 2.3 billion tons of carbon—about six years' worth of U.S. gasoline consumption, Khatiwala said.

For their study, Khatiwala and colleagues collected data on seawater temperature and salinity recorded from 1765 to 2008.

The team also gathered data on amounts of ocean pollutants called chlorofluorocarbons. These chemicals act as "tracers," allowing the scientists to figure out the time it takes for a substance to go from the surface of the ocean to the interior.

Based on this data, the team created a mathematical technique that allowed them to "work backward" to determine how much human-made carbon has entered the ocean over the years.

The researchers found that when human-made carbon dioxide began increasing dramatically in the 1950s, the oceans began absorbing more of that carbon.

But in recent decades the rate of absorbtion has declined, and the reasons for the slowdown are still unclear.

It might have something to do with increased carbon dioxide emissions making seawater more acidic, the authors say. That's because more acidic waters are less able to dissolve carbon dioxide.

Likewise, carbon dioxide can't dissolve as easily in warmer water—which is why about 40 percent of past carbon emissions were absorbed into the chilly oceans off Antarctica, according to the study, published tomorrow in the journal Nature.

Tremendous Service

The new results complement earlier observational studies of carbon dioxide in the oceans, including a 2004 Science paper by NOAA's Sabine and colleagues.

But Sabine cautioned that the new study doesn't take into account biological processes.

For instance, tiny algae called phytoplankton take up carbon dioxide through photosynthesis. When phytoplankton die, their remains drift to the depths and decompose—a natural cycle that keeps carbon trapped on the seafloor for centuries.

So far, scientists have assumed that this process hasn't really changed due to global warming, said study-co author Timothy Hall, a senior scientist at NASA's Goddard Institute for Space Studies.

But it's possible that warming seawater could set off a chain of effects that might damage the natural cycle, Hall said.

The oceans circulate water globally via a series of "pumps" that cause cold, dense waters to sink and nutrient-rich waters to rise.

Some of the pumps have not been functioning as well in recent years, leading scientists to speculate that warming surface temperatures may be to blame.

Less ocean mixing could means that fewer nutrients from the deep ocean are rising up to sustain phytoplankton, Hall said. Fewer phytoplankton mean less photosynthesis, which could lead to more carbon dioxide in the atmosphere.

"The oceans are performing a tremendous service for humankind," NOAA's Sabine said.

"If we throw [the oceans' carbon uptake] out of whack … the potential is there to completely overwhelm what we're trying to do with limiting our fossil fuel emissions."
