Wild boars hog the limelight in Thomson neighbourhood

WILD boars - in groups numbering up to 10 at a time - are creating a buzz in a quiet neighbourhood off Old Upper Thomson Road.

At dusk, the boars trot out from the undergrowth of the Lower Peirce Reservoir area and crash through trees and bushes onto Old Upper Thomson Road.

They roam along the road in search of food, oblivious to the occasional car zipping past or the camera flashes from curious onlookers.

Though residents of the more than 24 terrace houses and bungalows in the area said the animals have not attacked anyone, they have caused near accidents when they dash out onto the road at night.

Their sudden, and more frequent, appearances over the last few months have sparked amusement, and in some cases, fear in the neighbourhood.

Some keep the lids on their trash bins sealed tight to make sure they are not opened while the animals look for scraps. Others keep a wide berth, afraid of being attacked.

But residents like Ms Sylvia Pang are just happy with the 'novelty' of having such neighbours.

'They're interesting...We just have to be a bit more cautious, although they don't seem to cause any harm,' she said.

Marketing executive Lin Tan, 26, even had friends come over to her home for a 'stakeout' after she spotted the animals.

'I was excited and just had to take pictures. Seeing this right outside my house made me realise I live in such an interesting area,' she told The Straits Times.

She once saw as many as six - a sow and her piglets - outside her home.

The boars are safe for now. The authorities have no intention of capturing them and neither the Agri-Food and Veterinary Authority (AVA) nor National Parks Board (NParks) has received any reports about the boars attacking anyone or being killed.

Wild boars are commonly found within the forested areas around Lim Chu Kang, Mandai and Old Upper Thomson Road, say NParks and AVA.

No census has ever been taken of the size of the population.

Mr Biswajit Guha, Singapore Zoo's associate director of zoology, said boars tend to be secretive creatures that avoid confrontation.

However, increased sightings of these animals in urban, densely populated areas may mean that their natural habitats are 'highly disturbed' when forests are cleared to make way for new developments.

'It could also mean their numbers have multiplied in recent years, causing them to move beyond the areas they occupy,' Mr Guha said.

Wild boars are foragers and usually eat roots, fallen fruit and small mammals.

Residents who see these animals should not feed them, as they could become conditioned to receiving food from people and so become more daring about coming out into the open.

Said Mr Guha: 'Enjoy the fact that you are so lucky to be near wildlife and that it comes to your doorstep. But it's important to keep a respectful distance. Not every wild animal has to be admired close up.'

Protect those wild boars
Straits Times Forum 13 Feb 10;

I REFER to Monday's report, 'Wild boars hog the limelight in Thomson neighbourhood'.

It is gratifying to know of the existence of wildlife - particularly wild boars - near Lower Peirce Reservoir. Coexisting with animals of the wild and appreciation of nature can enrich our lives and bring immense joy and satisfaction to our world.

However, the report may also attract trappers to capture the animals for their meat. The incident last year is still fresh on our minds, when metal traps were used in Lim Chu Kang in a bid to trap wild boars. A dog was trapped instead and lost its hind leg in the process.

I hope the Agri-Food and Veterinary Authority and the National Parks Board will work closely to ensure that similar incidents are not repeated at Thomson.

Nuclear power: Time for a feasibility study

Elspeth Thomson , for the Straits Times 8 Feb 10;

THE Economic Strategies Committee in its recently released report, Ensuring Energy Resilience And Sustainable Growth, recommended that Singapore study the feasibility of nuclear energy and develop expertise in nuclear energy technologies.

In November 2008, Minister Mentor Lee Kuan Yew delivered the Singapore Energy Lecture at the annual Singapore International Energy Week. He noted that following the two oil crises, the Singapore Government had focused primarily on providing energy at reasonable cost. But now it had also to consider the consequences of CO2 emissions and climate change.

He commented: 'We can try and be the greenest city in the world and it's not going to make any difference in the outcome. So what's the point of it? Well, the point is if we don't do this, we'll lose our status as a clean, green city and we'll lose our business and we'll lose our extra premium for being an unusual city... The real alternative that can produce the electricity generation to match oil and gas is nuclear.'

He then went on to describe the siting problems of a nuclear plant in Singapore. Where to put it? Singapore is small and it is physically impossible to meet the 30km radius safety requirement for a nuclear power plant. This seemed to be the end of the story.

However, MM Lee was referring only to what might be called 'conventional' nuclear power plant technology. Things are changing. There are in fact now many more nuclear energy plant designs to consider than there used to be. Many modifications and improvements have been made since the horrific accidents which took place over 25 years ago at Three Mile Island in the United States and Chernobyl in the former Soviet Union.

Some power plant companies are now claiming that a buffer zone of only a couple of kilometres, or even less, is required and that the new plants have features which ostensibly greatly reduce the chance of accidents.

Yet we all know that the probability of a nightmare scenario can never be reduced to zero. This, and the seemingly impossible dilemma over where to put the radioactive waste that a nuclear plant produces are why Germans, for example, have voted to close down all existing nuclear power plants in the country and never build another.

In Asia, however, a nuclear renaissance is taking place. Dozens of new nuclear plants are under construction or being planned in China, Japan, South Korea, India and Pakistan - and also in Singapore's backyard: Vietnam, Thailand and Indonesia have announced their intentions to build nuclear power plants, while Malaysia and the Philippines are formally exploring the nuclear energy option.

Why? Because most of these governments face rapidly growing demand for electricity over the coming decades. They have few options other than the nuclear one and the costs are not insurmountable.

The region's oil resources are relatively small and dwindling and its gas reserves are also insufficient. Increased reliance on imported energy increases a country's vulnerabilities to price and supply shocks which can cause immediate and long-lasting economic and social damage. The planned massive increase in the use of coal to fuel hastily built thermal power plants in the short term flies in the face of global attempts to reduce carbon emissions. The development of renewables is uncertain, costly and cannot provide the vast quantities of reliable energy the region requires.

Singapore is currently producing from waste incineration only about 2 per cent of its electricity requirements. Eighty per cent of its electricity is generated from gas; and almost all of that gas comes from only two countries - Indonesia and Malaysia. Even if solar, geothermal and other renewable forms of energy were developed, Singapore would still remain in an extremely vulnerable position.

What Singapore needs to do in its 'study of the feasibility of the nuclear energy option' is to decide on what is an acceptable level of probability for a nuclear power plant accident.

Realistically, because Singapore is so small, if a major nuclear accident were to take place here, it faces becoming a nation of refugees. That degree of risk is obviously unacceptable.

But if what some major power plant companies are saying today about drastically reduced space requirements, improved safety features, and so on, is true, Singapore cannot afford not to consider the nuclear option.

There are now internationally recognised levels of risk attached to all of the new nuclear plant technologies and designs on the market. It is not the game of roulette that it used to be. Instead of dismissing the nuclear option outright, Singapore must carefully study these various levels of risk and get a sense of perspective.

What level of risk is acceptable? In planning the provision of reliable supplies of energy in 15 to 20 years' time, Singapore should carefully weigh and verify the claims of the nuclear power plant companies that are promising such high safety and reliability standards. Singapore should also learn from other countries' experiences and give the public ample opportunity to voice their concerns and share information.

A rough ride for electric scooters in Singapore

Esther Ng, Today Online 8 Feb 10;

SINGAPORE - So confident is it that there will soon be island-wide charging points, a homegrown electric vehicle (EV) company has powered onto the scene - even as one other before it has closed, and another has only managed sales of three electric scooters so far.

At its Kaki Bukit showroom yesterday, homegrown company Ampere launched its range of electric scooters, claiming that these are the first in the region to hit 75 kmh.

Its chief executive, Ms Hemalatha Annamalai said that with government support, the infrastructure will take off "in the next couple of months".

However, EV entrepreneurs who MediaCorp spoke to noted that the current transport system is not EV-friendly enough.

What is needed, they said, is some creative thinking and a change in attitude - rather than expensive infrastructure investment - to accelerate Singapore's EV transport system.

For example, the issue of who pays for the electricity used in charging EVs has to be resolved. Access to these power points has been a reason why electric scooters have not taken off in Singapore, they said.

At worst, someone can be accused of electricity theft if official permission has not been given to use them.

Currently, there are such 10 lots to be found across Singapore including those at Parkway Parade, and Ikea stores at Alexandra and Tampines. These have been set up by Greenlots, the infrastructure arm of Zeco Scooters. At present, these lots are seemingly under-utilised.

One way therefore is to incentivise property owners either by subsidising the cost of such infrastructure or by other means, said Mr Lin Zhuang, vice-president of Greenlots,

He cited the example of the City of Vancouver which recently passed a law requiring all new apartment buildings to equip 20 per cent of parking lots with charging infrastructure.

It launched its electric scooter last April, but Zeco has only sold three and these were to people living in landed homes.

This is because electric scooters are too bulky to be brought into lifts - and hence into homes - for charging.

They are also subjected to limited use as they are not allowed onto expressways. For EVs to succeed, there also has to be a fundamental change from motor insurers.

"We still face difficulty in securing comprehensive insurance coverage for electric vehicles. Underwriters are not willing to take the risk to insure a new product in the market, especially since there isn't yet a critical mass of (such) vehicles," said Mr Lin.

For similar reasons, it is harder to get an auto loan for an EV, he added.

Ampere's Ms Hemalatha said the company's scooters are priced between $5.500 and $7,500 and have to be pre-ordered.

It has also launched a range of electric bicycles in five models, priced between $749 and $999.

These have a top speed of 25 km/h and it costs six to nine cents to charge the lead-acid battery for a distance of up to 50km.

This can be done at home.

In comparision it costs less than one cent to charge an electric scooter's lithium battery.

Ample - another homegrown company - closed down last October. It had plans to commercialise plug-in hybrid EV technologies, battery electric vehicle technologies, vehicle-to-grid technologies and integration with renewable energy smart charging systems.

When contacted, founder Lim Kian Wee declined to comment, but Professor Ian Gibson from the National University of Singapore's (NUS) mechanical engineering department said the company had "run into financing problems".

"Our students are all very disappointed. They were looking towards working on converting conventional engines to hybrids and the hope of working for Ample," he said.

Ample had teamed up with NUS to work on a dozen such "conversion kits".

In an earlier email to MediaCorp, Mr Lim said his dream was to create 500 green jobs in the next three years.

Tax breaks to pave way for greener cars

EDB proposes big rebates to encourage plug-in hybrids
Christopher Tan, Straits Times 8 Feb 10;

EVEN as the wheels are in motion to get Singapore's maiden fleet of electric cars on the road, the Economic Development Board (EDB) is hoping that other 'green' vehicles will follow suit.

It is proposing that sizeable tax breaks be extended, for a start, to plug-in hybrids.

Plug-in hybrids are vehicles with combustion engines as well as motors powered by batteries which can be recharged via an electrical socket.

Typically, they can run on battery power for a far longer distance than ordinary hybrids, which have an electric engine charged by an internal combustion engine.

The batteries of the plug-in hybrids are recharged by the car's engine as well as its brakes.

Such plug-ins are seen as environmentally friendlier than ordinary hybrids, which are currently accorded a 40 per cent reduction in Additional Registration Fee (ARF) - the main car tax.

The Straits Times understands that the proposal is for plug-ins to be accorded the same tax break as the Energy Market Authority's fleet of trial electric cars, which are exempt from the ARF and Certificate of Entitlement.

An EDB spokesman would say only that the board is 'in the process of working on enhancing' the Transport Technology Innovation and Development Scheme.

Test cars brought into Singapore under the scheme wear blue-and-yellow number plates for research vehicles. Fleets in the past have included Daimler's hydrogen fuel-cell A-class cars; Honda Civic Hybrids used in a car-sharing scheme; and diesel cars running on a biodiesel blend.

As plug-in hybrids are not commercially available until next year or 2012, the EDB is said to be arranging for hybrids in Singapore to be converted into plug-ins.

Conversion typically involves changing and increasing the vehicle's battery pack, replacing the engine control unit and installing a plug-in point.

Prime Taxi, the only taxi company which has a fleet of hybrid cabs, has had preliminary talks with two companies which can do conversions: ST Kinetics and Delphi.

'We are keen to explore schemes that will help the environment,' said Prime Taxi managing director Neo Nam Heng. 'It does not always have to be the big companies which make a difference. A small operator like us can, too.'

ST Kinetics said it has been trying to promote plug-in conversions to vehicle manufacturers as well as fleet operators.

So far, it has delivered only one such vehicle: an aircraft tow tractor to Changi Airport.

ST Kinetics spokesman Gaius Ho said: 'For electric or hybrid vehicles to populate the city successfully, a large part has to start with the fleet owners.

'Hence tax incentives for such vehicles would need to be extended to fleet or transport operators.'

According to a recent report by British-based SupplierBusiness, plug-in hybrids will gain in popularity as governments the world over adopt stricter and stricter emission standards.

'Plug-in hybrids hold the promise of not only delivering very significant fuel economy gains over hybrids, but also hold out the possibility of very significant greenhouse gas reductions over the next 20 to 30 years,' the report said.

'A further important element to the growth of plug-in hybrids is their potential to reduce oil imports.'

On this front, Singapore has pledged to cut carbon dioxide emissions by 12 million tonnes by 2020. About two million tonnes of that will have to be cut from the transport sector, the largest carbon emitter after industry.

Some motor traders feel the most effective way of achieving this cut is to promote clean diesel vehicles and hybrids.

The Automobile Importer & Exporter Association of Singapore is lobbying to remove the ARF for hybrid vehicles and Euro 4 diesel commercial vehicles till the end of next year, when the Government is expected to announce a new carbon-based vehicle tax structure.

‘We cannot eat electricity’

www.thanhniennews.com 8 Feb 10;

The adverse impacts of climate change on the Mekong Delta in Vietnam will be amplified several times if hydropower dams planned upstream by other countries are built, experts say.

Both local and international experts said at a forum on the Mekong River environment organized by the Can Tho University on Wednesday that the dams will seriously threaten food security in riparian countries.

Dao Trong Tu, former Vietnam country coordinator for the Mekong River Commission, said three hydropower dams are already under construction in China, and another 11 were planned in Laos and Cambodia.

La Chhuon, an expert of Oxfam Australia in Cambodia, said fishermen in the country had told him they wanted to eat fish and would not be able to eat electricity generated by hydropower dams.

Without exception, every resident was unhappy with the building of dams and did not care for the compensation they would get when they are displaced by such projects, he added.

Carl Middleton, Mekong Program Coordinator of International Rivers, an INGO, that seeks to protect rivers and defend the rights of communities that depend on them, stressed that the projects threatened food security in the region.

He estimated that Mekong riparian countries would lose 700,000 to 1.6 million tons of fish a year to the dams, while this has been the main food for millions people there.

Who benefits?

Chuenchom Sangarasri Greacen of Palang Thai, a Thailand-based non-profit organization, said the predicted electricity consumption in Thailand was always higher than actual demand.

According to the Palang Thai website, it “works to ensure that the transformations that occur in the region's energy sector are economically rational, and that they augment, rather than undermine, social and environmental justice and sustainability.”

Sangarasri accused companies investing in hydropower projects of being motivated solely by economic benefit rather than helping fight power shortages. She said such motivations should be eliminated and more accurate assessments made of power needs.

Natural resources can meet genuine demand but cannot satisfy human greed for profit, she said.

Nguyen Huu Thien, a Vietnamese wetlands expert, said the river flows would be controlled by the managers of hydropower dams to the detriment of other people’s interests.

He said there would be less silt supplied by the river and farmers would have to spend more on fertilizers. The losses caused to farmers and other residents would outweigh by far the total benefits generated by dams, he added.

Activists argue that “dams will kill the mighty Mekong”
Vietnam Net 9 Feb 10;

VietNamNet Bridge – Losses in aquaculture and farm production could easily outstrip any profit from power generation if planned Mekong River dams are built in China, Laos and Cambodia, says a Can Tho University professor.

A forum organized by the Can Tho City government and a number of NGOs active in Vietnam and nearby countries on 3 February addressed the topic “The environment and livelihoods along the Mekong River.” The discussion aimed at finding ways to preserve the river’s rich bounty in the face of a rush to build dams in the river’s upper reaches. Reporters from the HCM City-based newspaper Tuoi Tre were present.

Dao Trong Tu, former vice secretary general of the Vietnam Committee for Mekong River, said that China is already building three of 16 planned hydropower dams while Laos wants to build an additional nine, and Cambodia two, dams on the river.

Electricity is not food

“We want to eat fish; we cannot live by eating electricity,” said La Chhuon, from the Oxfam Australia office in Cambodia, quoting Cambodian fishermen who live in the areas where dams are about to built. (Cambodia is making surveys for the construction of two hydropower dams on the Mekong between Phnom Penh and the Lao border).

Chhuon said that none of the fishermen interviewed were happy with the project of losing their livelihoods. They don’t want financial compensation. “If fishermen are moved to the mountain, what can they do to support their life?” Chhuon asked.

Dao Trong Tu said that the construction of dams will change the annual rhythm of flood and ebb, block the migration of fish and aquatic mammals, reduce the volume of alluvial soil, and otherwise do serious harm to the downstream area.

Dr. Carl Middleton of the International River Organisation, an American NGO, agreed with Tu, saying that the planned dam building not only affects the migration of aquatic animals but also seriously threatens food security in the region.

Middleton estimated that the countries located in the Mekong River basin will lose between 700,000 and 1.6 million tons of river fisheries production each year owing to the planned dams. The people along the river and in its delta, he pointed out, cannot easily switch to raising cattle and poultry as alternatives to their traditional reliance on protein from fish and aquatic products.

Meanwhile, Mak Sithrith, director of the Cambodian Fisheries Alliance, expressed worry that fisheries will be reduced because of dams. As a consequence, he predicted, fishermen will intensify efforts to catch fish in the remaining areas to offset the loss of other fisheries, resulting in exhaustion of aquatic resources and environmental pollution.

Are the dams really necessary?

Chuenchom, speaking for a Thai NGO, said that forecasts of electricity consumption in Thailand are always higher than actual consumption because the forecasts are the justification for private, semi-private and state companies to implement more hydropower projects and make more profits.

She said that many retired officials are on the payrolls of these companies. To get at the root of the problem, Chuenchom argued, profit considerations should be swept aside in planning power projects, and there must be realistic forecasts of electricity demand. “Natural resources can satisfy our needs but cannot satisfy our greed,” she emphasized.

Nguyen Huu Thien, an agronomist and wetlands specialist, warned that if 11 dams are built in Laos and Cambodia, the flow of the Mekong River would be under the control of the 11 plant managers. Once the river is barred by these dams, Thien predicted, the volume of rich silt carried to the Delta by the Mekong will fall drastically. The people who live in Vietnam’s Mekong Delta will have to pay more for fertilizer. Industries like fish processing and agricultural processing will be hard hit also. Thien calculated that the total loss of seafood and agricultural production may be greater than the value of electricity generation achieved by the hydropower plants.

Dr. Duong Van Ni from the Can Tho University said that after a survey trip to northern Cambodia with other sub-Mekong Region officials, Chinese experts realized that 50 percent of the items that are used by farm families there come from China. “China builds dams to develop industry,” Ni observed, “but if they have more products but the people who would buy them are impoverished, how can they sell them?”

Convincing data is needed

Nguyen Hieu Trung, dean of the Faculty for Environment and Natural Resources at Can Tho university, said that organizations and scientists should research, compile and publish data that proves the harmful impact of the planned hydropower dams on the economy, society and the environment – data that compels governments to reconsider their construction.

Dao Trong Tu, the former Mekong River Commission official, reminded that every nation has the right to build dams on its own territory. However, each nation must also bear in mind the impacts on its neighbors, he said, and seek to minimize bad consequences.

Tran Van Tu of the Vietnam Alliance of Scientific and Technological Association’s Can Tho branch, commented that it is man’s activities that threaten the Mekong River so the solutions must also come from man. He said it is not useful to confront governments, but essential to make every effort to persuade them.

A vice chairman of Can Tho City, Nguyen Thanh Son, underlined the consequences of failure. Protecting the environment and the productivity of the Mekong River is a vital requirement of the region, he said. “If a country seeks to take water just to satisfy its own need, there will be impacts on other countries. The long-term development in the entire region may come to a virtual standstill.”

Tiger found dead near attack spot

Sylvia Looi, The Star 8 Feb 10;

IPOH: The tiger that attacked an orang asli man at the Bukit Tapah Forest Reserve on Saturday has been found dead.

A team from the Perak Wildlife and National Parks Department (Perhilitan) found the male tiger with gunshot and blow pipe wounds within 100m from where it attacked the orang asli.

It had also lost its left forelimb.

State Perhilitan director Shabrina Shariff believes the animal could have escaped a trap set by poachers.

“The tiger might have attacked Yok Meneh because it was in pain,” she said yesterday.

“That is why I was surprised to read that the tiger had attacked a human as tigers are normally reclusive animals which keep to themselves,” Shabrina said.

The tiger tipped the scale at 120kg and measured between 1.5m and 1.8m in length. The tiger’s carcass is expected to be taken to the department’s Sungkai office for further checks.

Yok Meneh, a 47-year-old gatherer from the Semai tribe, was attacked while he was on his way to gather petai and suffered a deep wound measuring 15.2cm on his back.

He also suffered injuries to his hands and legs from fighting against the tiger.

Shabrina urged Yok Meneh to lodge a police report on the matter as he was entitled to compensation for being attacked by a fierce animal.

She said the department would recommend to the relevant authorities that Yok Meneh be compensated.

Sumatran tigers extinct by 2015: WWF

The Jakarta Post 7 Feb 10;

The Worldwide Fund for Nature predicts that Sumatran tigers (Panthera tigris sumatrae) may by extinct by 2015 due to poaching and loss of habitat.

“Destroyed ecosystems, which hamper the tigers’ ability to reproduce, will likely be an initial cause of the extinction. This condition may occur in the next five years,” Riau-based WWF official Osmantri was quoted as saying by news portal kompas.com on Sunday.

WWF has identified 30 Sumatran tigers, equal to 10 percent of the total animal population in the wild in Sumatra.

Between 1998 and 2009, 46 Sumatran tigers were found dead, mainly form poaching. The number shows that on average, seven tigers are killed each year. (nkn)

Urban growth, farm exports drive tropical deforestation

Yahoo News 7 Feb 10;

PARIS (AFP) – The biggest causes of deforestation in tropical countries are population growth in cities and agricultural exports, a finding that should shape decisions on preventing forest loss, experts said Sunday.

Under December's Copenhagen Accord, rich countries are pledging some 10 billion dollars over the next three years to help poor countries tackle climate change.

A big but so far unspecified chunk of the cash will go on programmes to prevent loss of tropical forests, which is a major source of greenhouse gases.

Beyond 2012, tens of billions of dollars per year could be primed if a planned UN pact on curbing climate change comes to fruition.

But environmental scientists publishing in the journal Nature Geoscience on Sunday cautioned against a rush to favour schemes that are unlikely to work.

A common theory is that pressure on forests can be eased by reducing the population in rural areas, or discouraging rural people from clearing land for fuel or food for their own use.

The study, led by Ruth DeFries of New York's Columbia University, looked at satellite data for forest loss in 41 countries from 2000 to 2005 and matched this against a host of other factors.

Two much bigger causes accelerated forest loss, they found.

One was the demographic growth of the host country's cities.

Urbanisation raises consumption levels and boosts demands for agricultural products. City dwellers eat more processed food and meat, which in turn encourages large-scale farming that leads to forest clearance.

The other factor is agricultural exports, which also amplified demands for farmland.

"The strong trend in movement of people to cities in the tropics is, counter-intuitively, likely to be associated with greater pressures for clearing tropical forests," says the study.

"We therefore suggest that policies to reduce deforestation among local, rural populations will not address the main cause of deforestation in the future."

Poor tropical countries thus face a dilemma if they want to feed their swelling cities, export food to gain wealth and preserve their forest treasure.

One solution, says DeFries, is boost food yields in lands that have already been cleared.

City Dwellers Drive Deforestation in 21st Century
Satellite data reveals that demand from urban areas may be the primary driver of the loss of trees--a shift from the patterns of the past
David Biello, Scientific American 8 Feb 10;

Globally, roughly 13 million hectares of forest fall to the blade or fire each year. Such deforestation has long been driven by farmers eking out a slash-and-burn living or loggers using new roads to cut inroads into pristine forest. But now new data appears to show that, at least for the first five years of the 21st century, big block clearings that reflect industrial deforestation have come to dominate, rather than smaller-scale efforts that leave behind long, narrow swaths of cleared land.

Geographer Ruth DeFries of Columbia University and her colleagues used satellite images from Landsat, along with the MODIS instrument on Aqua to analyze tree-clearing in countries ringing the tropics, representing 98 percent of all remaining tropical forest. Instead of the typical "fish bone" signature of deforestation from small-scale operations, large, chunky blocks of cleared land reveal a changing driver for cutting down woods: large enterprises feeding urban demand, according to a new paper published in Nature Geoscience on February 7. (Scientific American is part of Nature Publishing Group.)

In fact, a statistical analysis of 41 countries revealed that forest loss rates are most closely linked with urban population growth and agricultural exports from 2000 to 2005—even overall population growth was not as strong a driver. "In previous decades, deforestation was associated with planned colonization, resettlement schemes and local farmers clearing land to grow food for subsistence," DeFries says. "What we're seeing is a shift from small-scale farmers driving deforestation to distant demands from urban growth, agricultural trade and exports being more important drivers."

In other words, the increasing urbanization of the developing world—as well as an ongoing increase in consumption in the developed world for products that have an impact on forests, whether furniture, shoe leather or chicken fed on soy meal—is driving deforestation, rather than containing it, as populations leave rural areas to concentrate in booming cities. "One of the really striking characteristics of this century is urbanization and rapid urban growth in the developing world," DeFries says. ""People in cities need to eat."

"There's no surprise there," observes Scott Poynton, executive director of the Tropical Forest Trust, a Switzerland-based organization that helps businesses implement and manage sustainable forestry in countries such as Brazil, Congo and Indonesia. "It's not about poor people chopping down trees. It's all the people in New York, Europe and elsewhere who want cheap products, primarily food."

To help sustain this increasing urban and global demand, agricultural productivity will need to be increased on lands that have already been cleared, such as the many degraded and abandoned lands in the tropics, DeFries argues, whether through better crop varieties or better management techniques. And the Tropical Forest Trust is building management systems to keep illegally harvested wood from ending up in, for example, deck chairs, as well as expanding its efforts to look at how to reduce the "forest footprint" of agricultural products, such as palm oil. "The agricultural stuff, that's where the deforestation happens," Poynton says. "The point is to give forests value as forests, to keep it as a forest and give it a use as a forest. They're not going to lock it away as a national park, that's not going to happen."

Of course, tropical deforestation has allowed forest regrowth in other areas, including tropical lands previously cleared. And forest clearing in the Amazon, the world's largest tropical forest, has dropped from roughly 1.9 million hectares a year in the 1990s to 1.6 million hectares a year over the last decade, according to the Brazilian government. "We know that deforestation has slowed down in at least the Brazilian Amazon since the data we have for this study," DeFries says. "We looked very broadly over 41 countries. Every place is different. Every country has its own particular situation, circumstances and drivers."

Regardless, cutting down forests is one of the largest sources of greenhouse gas emissions from human activity—a double blow that both eliminates a biological system to suck up CO2 and a new source of greenhouse gases in the form of decaying plants. The United Nations Environment Programme estimates that slowing such deforestation could restore some 50 billion metric tons of CO2, or more than a year of global emissions, and international climate negotiations continue to attempt to set up a system to drive that, known as the U.N. Development Programme's fund for reducing emissions from deforestation and forest degradation in developing countries (REDD). "If policies [like REDD] are to be effective, we need to understand what the driving forces are behind deforestation," DeFries argues, and there are some new pressures looming. "Competing land uses for other products such as biofuels will exacerbate these pressures on tropical forests," the researchers wrote.

But millions of hectares of pristine forest remain to potentially save, according to this new analysis—60 percent of the remaining tropical forests are in countries or areas with little agricultural trade or urban growth. "The amount of forest area in places like central Africa, Guyana and Suriname," DeFries notes, is huge. "There's a lot of forest that has not yet faced these pressures."

It's Green Against Green In Mojave Desert Solar Battle

PlanetArk 8 Feb 10;

Twenty years ago when an epic clash over the logging of ancient redwood forests roiled California, the battle lines were clear-cut.

On one side stood a Texas corporate raider who acquired the Pacific Lumber Co. in a junk bond-fueled takeover and began felling vast swaths of primeval redwoods to pay off the debt. On the other side was Earth First! and other grass-roots greens who staged a campaign of civil disobedience to disrupt the logging. And while mainstream environmental groups may have looked askance at such tactics, they supported the cause in the courts, suing to stop the clear-cutting of ancient trees.

Today, another monumental environmental fight is unfolding in California over plans to build dozens of multi billion-dollar solar power plants in the Mojave Desert that could power millions of homes. But in this battle everyone is wearing green - from the solar developers seeking to generate carbon-free electricity, to feuding factions of environmentalists split over developing the desert.

The Mojave has become a metaphor for an existential crisis in the environmental movement as it tries to balance the development of renewable energy with its traditional mission to protect ecosystems.

In recent years, the movement's focus on wildlife, habitat preservation, and pollution has been eclipsed by the climate change imperative. National groups like the Natural Resources Defense Council, the Environmental Defense Fund, and the Sierra Club have joined with the more forward-looking members of the Fortune 500 to push cap-and-trade legislation and other climate-change initiatives and to promote alternative energy.

These disparate interests also have worked together to identify suitable areas to build large-scale solar farms. Over the past few years, Goldman Sachs, utility giants Pacific Gas & Electric (PG&E) and FLP Group, and a slew of Silicon Valley-backed startups have filed applications to build solar power plants on hundreds of thousands of acres of federal land in California's Mojave Desert and across the desert Southwest.

Now comes the backlash.

In December, this coalition found itself outflanked by a small Southern California group called the Wildlands Conservancy that persuaded U.S. Sen. Dianne Feinstein to introduce legislation banning renewable energy development on more than a million acres of the Mojave - including the land on which PG&E and others had set their sights. While hundreds of thousands of acres remain in the Mojave for potential solar farms, the area targeted by the Feinstein legislation had been particularly valued by developers for its proximity to transmission lines and the huge Southern California market.

Elsewhere in California's deserts, solar power plant projects have become bogged down as grassroots advocates challenge their impact on water resources, desert tortoises, and other rare animals and plants that inhabit a fragile arid ecosystem. For some, the desert is iconic and untouchable; for others it's a vast resource to be tapped.

After the Energy Policy Act of 2005 opened up the desert Southwest to renewable energy development, a solar land rush ensued.

When Feinstein, a California Democrat, first indicated she favored walling off a large swath of the desert from renewable energy development, Governor Arnold Schwarzenegger growled, "If we cannot put solar power plants in the Mojave Desert, I don't know where the hell we can put it."

I trekked into the desert to see for myself. A few days before Feinstein introduced her bill last December to create two new national monuments in the Mojave, I met David Myers, executive director of the Wildlands Conservancy, in Barstow and we set out for what he hopes will become the Mojave Trails National Monument.

You may never have heard of Myers, but the ardent conservationist has emerged as renewable energy power broker thanks to his connections to Feinstein and David Gelbaum, a press-shy Southern California financer turned philanthropist who bankrolls the Wildlands Conservancy. (So secretive is Gelbaum that a confidentiality agreement bars Myers from acknowledging his existence as a donor. Federal records show, though, that Gelbaum sits on Wildlands' board.)

A decade ago, Gelbaum - who has given $100 million to the Sierra Club, according to a 2004 Los Angeles Times story - contributed tens of millions of dollars for the Wildlands Conservancy's acquisition of a half-million acres of former railroad holdings owned by the Catellus Development Corp. The Catellus lands form a checkerboard of 640-acre parcels across the Mojave. Feinstein, who sponsored the 1994 legislation that created Death Valley and Joshua Tree national parks and the Mojave National Preserve, pushed for federal matching funds to complete the purchase of the land, which was then donated to the government for preservation.

But after President George W. Bush opened up the desert Southwest to renewable energy development in 2005, a solar land rush ensued, as developers proposed building some two dozen solar power plants and wind farms on federal lands that include the donated Catellus property. Myers then contacted Feinstein about preserving the lands by putting them into a vast new national monument.

"Al Gore called these lands out here some of the most pristine and scenic desert lands in the world," says Myers as we cruise down Route 66 in his Subaru. He pulls over and we walk across the road to take in the sweep of the Sleeping Beauty mountain range that rises from a broad valley where BrightSource Energy and other solar developments had proposed building massive solar power plants.

"You have this incredible landscape of these bighorn sheep corridors back and forth across the valley," says Myers. "You couldn't put a project in a worse area from a landscape connectivity point of view... It's a philosophic non-sequitur that you can destroy hundreds of thousands of acres to save the Earth from global warming."

The vistas and wildlife in this stretch of the Mojave are indeed spectacular, if not totally pristine - power lines march across the desert floor and some ranges are scarred by mining operations.

BrightSource Energy, which built this demonstration solar complex in Israel, has filed an application to build a 400-megawatt solar power plant in Southern California.Establishment environmentalists tend to dismiss Myers as a "purist" who is unwilling to consider solar development in the desert.

"I don't think many in the environmental community share the extreme views of people like David Myers - I think he's an outlier," says John White, executive director of the Center for Energy Efficiency and Renewable Technologies in Sacramento, which is involved in a state-federal effort to identify desert areas suitable for solar development.

The soft-spoken Myers is no Earth Firster. He says he supports solar development in other parts of the Mojave but prefers power plants be built on degraded farmland, or better yet, through a massive expansion of rooftop solar arrays. The Feinstein legislation includes provisions designed to speed up the licensing of renewable energy projects on federal land elsewhere in the desert and provides incentives to developers who build on former farmland.

"We don't have to choose between having renewable energy development or complying with the Endangered Species Act," says Johanna Wald, a senior attorney with the Natural Resources Defense Council in San Francisco who is also participating in the solar planning process. "We can have them both, and certainly the California experience is that we have the resources to do both."

Still, Myers has thrown a monkey wrench in plans to tap about 10,000 megawatts of electricity in this area before its environmental value could be formally evaluated, as is being done elsewhere in the Southwest. While the monument legislation's success is by no means assured, most of the solar developers - including BrightSource Energy, Goldman Sachs, and Tessera Solar-had abandoned their projects before the bill was formally introduced in late December. No one, it seemed, wanted to take on Feinstein, who first raised concerns about the projects last spring.

"Senator Feinstein's proposal created a fair amount of uncertainty and we wanted to collaborate with the senator and make sure we were investing our time and effort in the area with potential to go forward," Sean Gallagher, Tessera's vice president for regulatory affairs, told me in December after the company canceled its plans for a massive 12,000-acre solar farm, whose peak output would have equaled that of a nuclear power plant.

PG&E, FPL, and Iberdrola Renewables, the Spanish renewable energy giant, say they are either cautiously proceeding or re-evaluating their Mojave projects in light of the legislation. Most developers have staked multiple land claims elsewhere in the Southwest. (That, of course, doesn't mean they're happy about the situation. "Iberdrola Renewables believes the environmental community is taking away one of the few places in the U.S. suitable for utility-scale solar development," Jan Johnson, a company spokeswoman, wrote in an e-mail.)

So we return to the governator's question: Where can you put a solar power plant?

That question was being debated last month in Sacramento at California Energy Commission hearings on the state's first new solar power plant to undergo licensing in two decades.

In August 2007, BrightSource Energy, an Oakland, Calif.-based startup, filed an application to build a 400-megawatt solar power plant in the Ivanpah Valley - an area outside the Feinstein monument area - just over the Nevada border in Southern California.

BrightSource - which is backed by Google, Morgan Stanley, and a clutch of oil companies - has signed contracts to deliver 2,600 megawatts of electricity to California utilities, which is needed to secure 24,000 megawatts of renewable energy by 2020 to meet state mandates. John Woolard, BrightSource Energy's chief executive, alluded to the difficulty in finding suitable desert land for solar power plants. "Frankly, it says a lot that Ivanpah's the only site that we think we're able to build on right now inside of California," he said.

The surrounding desert landscape would not inspire Edward Abbey. Interstate 15, which connects Los Angeles to Las Vegas, slices through the area. A few miles from the BrightSource site, Buffalo Bill's and Whiskey Pete's - two hulking casinos connected by a monorail - rise from the desert like an apparition from a Mad Max movie. Adjacent to the solar site sits a 22-acre golf course that consumes a half-billion gallons of water a year. To the west are two mines and a pipeline that carries mining waste to an evaporation pond.

After an extensive two-and-a-half-year environmental review, the energy commission concluded in late 2009 that the BrightSource project "would have major impacts to the biological resources of the Ivanpah Valley, substantially affecting many sensitive plant and wildlife species and eliminating a broad expanse of relatively undisturbed Mojave Desert habitat."

The project would sit on 4,000 acres of habitat, home to 25 desert tortoises, as well as rare plants like the Mojave milkweed. The tortoises must be removed and suitable replacement habitat purchased for them, the energy commission said.

While the Sierra Club's national organization has supported desert solar power plants, a local chapter has challenged the Ivanpah project, joining Defenders of Wildlife and other environmental groups in urging that the project be reconfigured and moved closer to the highway to lessen the impact on the tortoise.

Even if BrightSource abandons Ivanpah, the industrialization of the desert will proceed apace. According to the California Energy Commission, some of the projects on the drawing board for the surrounding area include a 500-megawatt natural gas power plant and an airport on the Nevada side of the border, as well as seven other massive solar power plants to be built within miles of the BrightSource site.

The party line among greens of all hues is that we can have it all - renewable energy production and protection of wildlands. That may well be true, but there will have to be some hard choices made about just what kind - and how much - development we want in the desert.

Water at core of climate change impacts: experts

Alister Doyle, Reuters 7 Feb 10;

OSLO (Reuters) - The main impact of climate change will be on water supplies and the world needs to learn from past cooperation such as over the Indus or Mekong Rivers to help avert future conflicts, experts said on Sunday.

Desertification, flash floods, melting glaciers, heatwaves, cyclones or water-borne diseases such as cholera are among the impacts of global warming inextricably tied to water. And competition for supplies might cause conflicts.

"The main manifestations of rising temperatures...are about water," said Zafar Adeel, chair of UN-Water which coordinates work on water among 26 U.N. agencies.

"It has an impact on all parts of our life as a society, on natural systems, habitats," he told Reuters in a telephone interview. Disruptions may threaten farming or fresh water supplies from Africa to the Middle East.

"Therein lies the potential for conflicts," he said. Shortage of water, such as in Darfur in Sudan, has been a contributing factor to conflict.

But Adeel said that water had often proven a route for cooperation. India and Pakistan have worked to manage the Indus River despite border conflicts and Vietnam, Thailand, Laos and Cambodia have cooperated in the Mekong River Commission.

"Water is a very good medium (for cooperation). It's typically an apolitical issue that can be dealt with," said Adeel, who is also director of the U.N. University's Canada-based Institute for Water, Environment and Health.

250 MILLION

Regions likely to become drier because of climate change include Central Asia and northern Africa. Up to 250 million people in Africa could suffer extra stress on water supplies by 2020, according to the U.N. panel of climate experts.

"There are many more examples of successful transboundary cooperation than conflict over water," said Nikhil Chandavarkar, of the UN Department of Economic and Social Affairs and Secretary of UN-Water.

"We are trying to take the examples of good cooperation -- the Mekong, the Indus are examples. Even where there were hostilities in the surrounding countries the agreements did function," he told Reuters.

Adeel said that water should have a more central role in debates on food security, peace, climate change and recovery from the financial crisis. "Water is central to each of these debates but typically isn't seen as such," he said.

And efforts to combat global warming will themselves put more strains on water because of rival economic demands -- such as for irrigation, biofuels or hydropower.

Adeel noted efforts to manage water supplies by counting how much water goes into products -- from beef to coffee.

One study showed that it took 15,000 litres to produce a pair of blue jeans, he said. Making industries aware of water use could help shift to conservation. He said the world might reach a "millennium goal" of halving the proportion of people without access to safe water by 2015 but was failing in a related target of improving sanitation. About 2.8 billion people lack access to basic sanitation.

Drought in SW Australia linked to snowfall in Antarctica

Yahoo News 7 Feb 10;

PARIS (AFP) – A drought that has gripped the southwestern corner of Australia since the 1970s is linked with higher snowfall in East Antarctica, a phenomenon that may be rooted in global warming, scientists reported on Sunday.

Researchers Tas van Ommen and Vin Morgan of the Australian Antarctic Division said that the drought -- which has seen winter rainfall decline by 15-20 percent -- is extremely unusual when compared with the last 750 years.

Hand in hand with the drought is a similarly exceptional rise in snowfall at Law Dome, an icecap on the coast of East Antarctica.

The apparent reason is a "precipitation see-saw," the pair report in a paper published online by the journal Nature Geoscience.

Relatively cool, dry air flows northwards to southwest Australia, providing little rain, while warm, moist air flows to East Antarctica, where it provides abundant snow.

The pattern is consistent with previous studies that suggest a man-made role in the drought, say the pair.

Previous research has pointed to greenhouse gases for changing the so-called Southern Annular Model, a key feature of atmospheric circulation in the southern hemisphere.

Soot adds to rise in global warming

Michael Richardson, For The Straits Times 8 Feb 10;

A TEAM from the Chinese Academy of Sciences trekked across frigid highlands in Tibet to confirm a significant recent discovery about climate change.

They drilled and analysed five ice cores from various locations on the Tibetan plateau to find that the concentration of black carbon, or soot, in the ice had increased to between two and three times the level in 1975.

At Zuoqiupu glacier, on the southern edge of the plateau downwind from the Indian subcontinent, black carbon deposition rose by 30 per cent between 1990 and 2003.

What are the implications of this and other related findings by numerous researchers from different countries and scientific agencies in recent years?

International efforts to combat global warming focus on cutting six greenhouse gases. A panel of scientists advising the United Nations has concluded that these gases - chiefly carbon dioxide, methane and nitrous oxide - are most likely responsible for warming the planet to potentially dangerous levels.

A growing body of research in the past few years points to another potent source of human-induced warming: airborne aerosol particles, especially black carbon, a key component of soot.

When coal, oil and other fossil fuels are burned without enough oxygen to complete combustion, one of the by-products is black carbon. A similar process takes place with the burning of biomass, including cow dung and crop residues, although the by-product is mainly organic carbon which scientists say has less of a warming effect than black carbon.

Asia is now the leading global source of the tiny particles of soot from this incomplete burning. They rise into the atmosphere and mix with different emissions, including nitrates and sulphates, to form aerosols.

Black carbon absorbs sunlight, as do other greenhouse gases. But particles of sulphate or nitrate alone reflect solar radiation, thereby cooling the planet. Indeed, advocates of geo-engineering to combat global warming have proposed pumping sulphate aerosols into the atmosphere to slow climate change.

However, Professor Kimberly Prather of the University of California in San Diego and a colleague published research last year showing that sulphate and nitrate play a different role when they mix with black carbon.

Their study showed that jagged bits of fresh soot quickly become coated with a spherical shell of other chemicals, particularly sulphate, nitrate and organic carbon, through light-driven chemical reactions.

'The coating acts like a lens and focuses the light into the centre of the particle, enhancing warming,' Prof Prather says. The measurements showed that in the atmosphere the aerosol combination increased the warming effect of the coated black carbon particles 1.6 times over pure black carbon particles.

North America and Europe have reduced aerosol levels by enacting clean air regulations and transport fuel standards. Developing Asian economies have been slower to follow.

The extensive soot-laden pollution Asia produces now shows up in satellite photographs as a gigantic brownish haze stretching over large parts of South and South-east Asia and China. This haze is a health hazard as well as an extra source of global warming.

As the pollution is carried by prevailing winds in the northern hemisphere, it affects other countries that have cleaner air standards such as Singapore, Japan and the United States.

Aerosols have another warming effect. The coated black carbon particles do not waft around forever. As winds drop, they are deposited on earth's land and sea surfaces, including snow and ice, creating a smudging effect. The dirty snow and ice absorb more sunlight than pure snow and ice, which reflect light.

By some measures, black carbon accounts for roughly half the global warming potential of carbon dioxide, the main greenhouse gas. Moreover, while carbon dioxide can stay in the atmosphere for over a century, aerosols remain only for a few weeks at most.

Could tighter international controls on soot emissions provide a quick fix for climate change? A growing body of evidence suggests that black carbon can be controlled more easily than greenhouse gases like carbon dioxide.

An Indian-Swedish research team has concluded that about two-thirds of the soot-laden brown cloud pollution in Asia comes from biomass burning (mainly household cooking and slash-and-burn agriculture) and one-third from fossil fuel combustion.

They and other scientists have called for a rapid scaling-up of programmes to discourage open air burning and spread the use of low-cost but efficient household stoves and biogas.

'While reducing carbon dioxide concentrations is extremely important, changes we make today will not be felt for quite a while, whereas changes we make today on soot and sulphate could affect our planet on timescales of months,' says Prof Prather.

'This could buy us time...'

El Nino to bring drier-than-average conditions to Indonesia in Feb-April

Antara 6 Feb 10;

Jakarta (ANTARA News) - El Nino`s expected impacts during February-April 2010 include drier-than-average conditions over Indonesia, according to the US Climate Prediction Center (CPC).

The CPC in its El Nino Advisory sent to ANTARA by e-mail on Friday said a significant El Nino persisted throughout the equatorial Pacific Ocean during January 2010.

Although sea surface temperature (SST) departures in the Nino-3.4 region decreased to +1.2 degree C in late January, SSTs continued to be sufficiently warm to support deep tropical convection.

Equatorial convection over the central Pacific remained enhanced during the month, while convection over Indonesia exhibited considerable week-to-week variability, according to the Maryland-based CPC.

Over the last several months, a series of oceanic Kelvin waves contributed to the build-up of heat content anomalies in the central and eastern Pacific.

The latest Kelvin wave was associated with temperature departures exceeding +2 degrees C down to 150m depth across the eastern half of the equatorial Pacific.

While the low-level winds have been variable, low-level westerly and upper-level easterly wind anomalies generally prevailed during January. Collectively, these oceanic and atmospheric anomalies reflect a strong and mature El Nino episode.

Nearly all models predict decreasing SST anomalies in the Nino-3.4 region through 2010, and model spread increases at longer lead times.

Nearly half of the models indicate the 3-month Nino-3.4 SST anomaly will drop below +0.5 degree C around April-May-June 2010, indicating a transition to ENSO (El Nino Southern Oscillation -neutral conditions during Northern Hemisphere spring. However, predicting the timing of this transition is highly uncertain.

El Nino impacts are expected to last into the Northern Hemisphere spring, even as equatorial SST departures decrease, partly due to the typical warming that occurs between now and April/May.

For the contiguous United States, potential El Nino impacts include above-average precipitation for the southern tier of the country, with below-average precipitation in the Pacific Northwest and Ohio Valley.

Below-average snowfall and above-average temperatures are most likely across the northern tier of states (excluding New England), while below-average temperatures are favored for the south-central and southeastern states.

This discussion is a consolidated effort of the National Oceanic and Atmospheric Administration (NOAA), NOAA`s National Weather Service, and their funded institutions. Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Nino/La Ninaa Current Conditions and Expert Discussions).

Forecasts for the evolution of El Nino/La Nina are updated monthly in the Forecast Forum section of CPC`s Climate Diagnostics Bulletin. The next ENSO Diagnostics Discussion is scheduled for 4 March 2010.
