Georgia Aquarium: New fish every 90 days

Downtown Atlanta attraction wants to pump up ‘wow factor’
Leon Stafford, The Atlanta Journal-Constitution 21 Aug 08;

In an effort to increase attendance, the Georgia Aquarium will add a “wow factor” fish to its waters every quarter, interim Chief Executive Officer Mike Leven says.

“We need to ensure that every 90 days or so we have new things coming to the aquarium,” Leven said, flipping through a stack of possible candidates such as barracuda, tiger sharks and colorful yellowfin tuna. “You have to constantly upgrade and bring in new and interesting animals. They are a critical component to our growth.”

But Jeff Swanagan, the former head of the aquarium, is not convinced such a quick turnaround is possible. He said fish can be quarantined for as much as 45 days depending on species or size. If there’s a problem, quarantine can last even longer, he said.

“That will be virtually impossible to do,” Swanagan, now executive director of Ohio’s Columbus Zoo and Aquarium, said of Leven’s plan. “But if there is a place that can do it, it’s the Georgia Aquarium.”

Steve Feldman, a spokesman for the Association of Zoos and Aquariums, agreed. He said he was not aware of any aquarium with the kind of timeline Leven is suggesting, but he said the Georgia Aquarium has the expertise to pull it off.

Leven said his aggressive plan to introduce new “charismatic” fish every quarter is a sea change from the course the world’s largest fish tank has been charting. With the exception of a handful of smaller species and the four whale sharks that replaced Ralph and Norton, who died last year, the aquarium’s inhabitants have mostly been the same since the tank’s opening in November 2005.

Leven said that inertia may have stopped some visitors — especially locals, who are the bread and butter of the attraction — from coming back a second and third time, which is crucial to the aquarium’s bottom line. While the slumping economy has contributed to the attendance drop, he said he believes the aquarium has not given visitors enough reasons to come back.

“No business can exist on creating new customers all the time,” he said. “It’s a very expensive and difficult process.”

Plus, aquarium spokesman Dave Santucci said, giving visitors more reasons to come back increases the possibility of turning frequent visitors into annual pass holders.

“People are much more likely to join if it is a changing, dynamic institution rather than a static institution,” Santucci said.

While attendance is down, Santucci was quick to point out that the aquarium is not foundering. Attendance this year is projected to be about 2.2 million visitors, handily one of the most visited fish tanks in the country.

Leven, who made his name in the hospitality industry as the head of hotel brands Days Inn and later Holiday Inn, took over as the leader of the aquarium in June after Swanagan stepped down.

Since then, Leven has accepted the resignations of two top aquarium officials and reshuffled other positions. Last week, he announced the traveling Titanic exhibit, which was in Atlanta in 2006 — would come to the aquarium beginning Aug. 22.

Northwestern University branding expert Tim Calkins said attractions have to keep interest up to stay on the radar.

“The challenge for any organization today is to stay relevant,” he said. “When an institution is brand-new, a whole lot of people will come in to see it. That’s easy. But what happens when they’ve all visited?”

This may have been a question that aquarium founder Bernie Marcus, the billionaire co-founder of Home Depot, wanted answered, too. He asked Leven, who at the time ran Marcus’ private foundation, to look at the aquarium and its direction.

In May, Leven said he reported to Marcus that the aquarium needed to be run more like a business, including naming a new CEO, though he would have left Swanagan as chief operating officer and president.

Putting new fish on display every 90 days has its risks, Leven said. In addition to finding the fish and quarantining them for 30 to 45 days to monitor their health, the aquarium also would have to find specimens that can either survive predators or don’t eat the tank’s inhabitants.

The cost of bringing in new fish depends on the size and variety, Santucci said. Most of the money — anywhere from pennies to hundreds or thousands of dollars — is spent on transportation and labor.

Sky Lantz-Wagner, who operates Dove 6, an Atlanta-based whale shark tourism business in Cancun, Mexico, said he doesn’t think a new fish every 90 days is the answer to strengthening attendance. Introducing new fish rapidly can be intrusive to the attraction’s eco-system.

Plus, he said, how do you top a whale shark?

“It sounds a little gimmicky to me,” he said. “It’s not the circus, it’s an aquarium.”

Aquarium shake-up is about boosting visits
Interim CEO cites slowdown in repeat business
Leon Stafford, The Atlanta Journal-Constitution 5 Aug 08;

The recent staff shake-up at the Georgia Aquarium — which saw the resignations of some of the attraction's top officials and the promotions of others — is part of an overall strategy to boost visitation, says interim Chief Executive Officer Mike Leven.

After three years as one of Atlanta's top attractions, the world's largest fish tank — which opened with 3.6 million visitors in November 2005 — has seen a 37 percent decline in attendance this year, Leven said Tuesday.

And while the mortgage meltdown and high gas prices have played a role — many attraction nationwide have seen attendance fall — Leven said he thinks a bigger reason is a slowdown in repeat business.

"I can't take the risk of that trend going to 1.9 million or 1.8 million," he said. "You've got to change the basic strategy of how you're working.

With a goal of boosting annual visitation to 3 million by 2011, Leven is instituting changes that include beefing up sales in the states surrounding Georgia and altering the regulations to make it easier to use the facility's banquet areas.

Leven, interim director since former Executive Director Jeff Swanagan announced his resignation in May to head up the Columbus (Ohio) Zoo and Aquarium, said he also will dramatically increase the number of new animals on exhibit.

"We want people to come back to the aquarium," said Leven, who expects attendance to jump when dolphins are added during the aquarium's five-year anniversary in November 2010. "It's not that crowded, except on Saturdays."

Not all those leaving bought into his vision, he said.

Last Thursday, Ray Davis, senior vice president of zoological operations, and Tim Binder, director of animal husbandry who reported to Davis, both resigned.

"These guys made very significant contributions to the aquarium, but they have decided to move on," aquarium spokesman Dave Santucci said.

Mike Hurst, vice president of plant engineering and operations, lost his job because the reorganization made it redundant, said Santucci.

Santucci said the aquarium "will be actively searching for replacements" for Davis and Binder.

Tim Mullican will act as the supervisor of husbandry until the positions are filled, Santucci said.

The aquarium employs about 240 full-time workers, 250 part-timers and 1,100 volunteers.

Because of the aquarium's success out of the gate — officials were expecting only about 2 million visitors the first year — Leven said some in management were not adapting to change quick enough.

"The organization was not prepared to make changes for the downturn in attendance," he said. "We did so well the first year that people didn't react with urgency because they didn't have the time.

"If the senior leadership doesn't buy into that strategy, you have to change," he said.

On Monday, Leven notified aquarium staff of a series of promotions.

Anthony Godfrey was promoted to executive vice president and chief operating officer; Carey Rountree became senior vice president, sales and marketing; Deb Parsons became vice president, human resources & cultural development; and Santucci became vice president, marketing & communications.

The aquarium has received criticism for its push to attract visitors, especially its recently introduced program that lets tourists swim with its whale sharks. Some say it has become more of an entertainment venue than learning center.

Leven said the facility is committed to research and education, two of its key missions. But it has to pay the bills.

"You have to be financially viable," he said. "Entertainment is purely a strategy to pay for it."

Other promotions include: Meghann Gibbons as director of public relations; Ashley Payne, manager of e-communications and new media; Michaelanne Dye, specialist of e-communications and new media; Will Ramsey, vice president of sales.

Also: John Walker, senior manager group sales; Kristie Cobb, vice president, development & membership; Karen Deaton, vice president, advertising, exhibits & creative services; and John Chapman, director, facilities maintenance.

Got a plan to harvest solar energy?

Today Online 21 Aug 08;

SINGAPORE’S Clean Energy Programme Office (Cepo) is making an international call for research and development proposals to develop solar harvesting devices and systems for the tropics.

The reason? Most systems today are optimised to operate under temperate climates, in countries such as Germany and Japan, home to some of the largest global markets for solar energy.

There is, however, a lack of solar systems tailored for hot and humid tropical climates. With this grant call, which comes under the $50-million Clean Energy Research Programme (Cerp), Singapore hopes to develop the know-how that could speed up solar adoption in the tropical region.

As Singapore’s urbanised landscape is representative of many cities in the tropics, there is “vast market potential for the export of clean energy solutions developed here”, said the Economic Development Board in a press release.

Winning proposals will have access to test-bedding sites here, including high-rise apartment blocks as well as industrial and commercial buildings.

Applicants should submit a preliminary research proposal before Oct 20. Short-listed applicants will be notified to submit a full proposal by Jan 5. More details are at rita.nrf.gov.sg/ewi/CERP_02.

This is Cerp’s second call for research proposals. Following its first call last November, eight of the 60 proposals that were submitted were last month awarded grants totalling $10 million. The proposals spanned a wide range of technologies in the solarenergy field, including novelphotovoltaics technologies such as dye-sensitised solar cells.

Cerp was launched last October to boost research and development efforts to help drive the growth of the clean energy industry here.

Energy sector can fuel Singapore manufacturing growth

Singapore just needs intellectuals with adaptable skills: Warwick director
Oh Boon Ping, Business Times 21 Aug 08;

SINGAPORE is well-placed to take advantage of the sustainable energy sector to fuel future manufacturing growth.

'It does not require millions of workers, but a pool of intellectual people with highly adaptable skills,' a breakfast dialogue session at the Singapore Institute of Management heard yesterday.

Singapore already has the necessary intellectual base as there is a sizeable talent pool here, said Kumar Bhattacharyya, director of the Warwick Manufacturing Group and chairman of the Economic Development Board's Manufacturing Excellence Awards.

Prof Bhattacharyya also highlighted three developments that present opportunities and challenges.

The first is terrorism, which has spurred the growth of the security industry to US$200 billion in the developed world, he said.

And beyond terrorism, the security industry 'now has a much wider role to play in areas such as identification and information'.

Second, Prof Bhattacharyya cited growing concern about climate change and a focus on renewable energy.

As a result, many countries have raised spending on R&D, while new sectors such as solar energy have been created.

Third, life expectancy is increasing, and consumers demand better primary health care.

This, said Prof Bhattacharyya, will determine the type of diagnostic devices that need to be produced to meet people's needs.

Also at yesterday's breakfast session was Lee Kwok Cheong, CEO of SIM Private, who emphasised the importance of nurturing 'thinking' engineers in Singapore.

For this reason, SIM has partnered A*Star's SIMTech and the Warwick Manufacturing Group - from Britain's University of Warwick - to run a master's course that trains students in operational excellence, business strategy and how they affect business profitability.

To stem the outflow of engineering talent, EDB assistant managing director Manohar Khiatani suggested that more 'non-traditional' engineering courses be introduced to make the curriculum more interesting.

Meanwhile, Singapore's Clean Energy Programme Office (CEPO) yesterday called for R&D proposals to develop roof-mounted solar energy harvesting devices and systems for the tropics, under the $50 million Clean Energy Research Programme (CERP).

With this grant call, Singapore aims to develop expertise and know-how that can contribute to the acceleration of solar adoption in the tropics.

'The tropical region holds exciting market potential for solar energy, especially with the many fast-growing urban centres and its rich solar energy radiation,' CEPO said in a statement.

CERP was launched in 2007 to accelerate research and development efforts to help drive the growth of a clean energy industry in Singapore.

The initiative supports upstream and downstream commercially relevant R&D efforts through a project funding approach.

New, "Chubbier" River Dolphin Found in Bolivia

José Orozco, National Geographic News 20 Aug 08;

The Bolivian river dolphin is a separate species from the Amazon river dolphin, scientists announced recently.

Thousands of years ago a powerful drought dried up Brazil's Madeira River, causing a "radical separation" as dolphin populations were caught on different sides of the newly created rapids, said researcher Manuel Ruiz-Garcia.

The Madeira split into today's Beni and Mamoré rivers of northeastern Bolivia.

"When they separated, [the dolphins] were never again able to return and reproduce," said Ruiz-Garcia, who heads the Molecular Genetics Lab at Javeriana University in Bogotá, Colombia.

"Thus isolated, the Bolivian river dolphin, Inia boliviensis, eventually developed," he said.

The announcement was made at a recent conservation workshop in Santa Cruz de la Sierra in Bolivia.

Genetic Differences

Ruiz-Garcia took DNA samples from 40 river dolphins from Bolivia and 56 from Colombia by extracting tissue from their tail muscles.

A limited comparison of the DNA revealed significant genetic differences between the two river-dolphin populations.

This led Ruiz-Garcia to initially estimate that the species separated five to six million years ago.

But after comparing 32 more genes from DNA in another 40 Bolivian dolphins and about 60 Colombian and Peruvian dolphins, he concluded that the separation happened much sooner—about 100,000 to 500,000 years ago.

"Bolivian dolphins are totally different molecularly from other dolphins," Ruiz-Garcia said. "After being split up, they accumulated mutations and formed a new species."

Bolivian river dolphins—especially females—also look different from their Amazon relatives.

In contrast to Amazon river dolphins, which are considered "pink," the members of this new species are a pale gray. They also have more teeth, smaller heads, and smaller bodies.

Ruiz-Garcia also considers the Bolivian species to be chubbier and rounder.

The latest genetic studies on the newly declared species allow "a very clear reconstruction of evolutionary history," said Fernando Trujillo, scientific director of Colombia's Fundación Omacha and the leader of South America's first river-dolphin census in 2007.

The River Dolphin Monitoring initiative for South America counted 3,188 river dolphins along 2,232 miles (3,593 kilometers) of the Amazon and Orinoco rivers and their tributaries.

Vulnerable

The Bolivian river dolphin population may include as many as 25,000 individuals, making the mammal "very abundant," Ruiz-Garcia said.

And unlike the havoc wrought on its relatives by fishers on Brazilian rivers, Bolivia's newfound dolphin can roam safely through pristine freshwater channels.

Yet the mammal still remains vulnerable to environmental disruptions, experts say.

"They're very vulnerable predators," said Paul Van Damme, a researcher for Faunagua, a Bolivian organization that monitors dolphins. "So if fish are affected, they're the first to feel the effects."

For example, if a river fills with mercury, dolphins that eat contaminated fish consume the accumulated metal.

"The dolphins are a reflection of the entire aquatic system," Van Damme said.

The animal's greatest threat comes from a Brazilian dam that could raise the water level, alter the river flow, or divert the migration of fish, experts say.

A water-level rise could allow dolphins from both sides of the rapids to move back and forth again for the first time in over a hundred thousand years, Ruiz-Garcia said.

But such a reunion would soon turn tragic, he added.

"The Amazon river dolphin could compete against the Bolivian river dolphin for food, and perhaps bring about its extinction."

A new regional network of 18 scientists have created a conservation plan, which includes economic activities such as dolphin-watching ecotours.

Mexico starts campaign to save endangered porpoise

Dan Keane, Associated Press 21 Aug 08;

Mexico is investing 163 million pesos (US$16 million) to save a highly endangered type of porpoise from fishing nets in the upper Gulf of California.

Scientists say they believe the population of the vaquita marina — Spanish for "little sea cow" — has dwindled to 150 or less from more than 500 a decade ago.

"It's a critical time for the vaquita, and the Mexican government has stepped up to the plate," said Peggy Turk Boyer, executive director of the Intercultural Center for the Study of Desert and Oceans, a U.S.-Mexican institution that will help survey the population of the porpoises this fall.
The money will be dedicated to stepping up enforcement of fishing regulations in the warm, still waters of the far northern Gulf, a designated nature preserve.

The government also will use the funds to buy nets from local fishermen, who will be taught other fishing methods or be trained in new trades. The big nets drown dozens of vaquitas each year.

Also known as the Gulf of California porpoise, the elusive vaquita was only discovered in 1958. The animal resembles a dolphin, but rarely jumps from the water and avoids boats, making an accurate population count difficult.

The vaquita also is threatened by the dwindling flow of the Colorado River into the gulf. Depleted by western U.S. cities for drinking water, the river carries high levels of agricultural runoff that can significantly alter the gulf's chemistry.

Ivory trade banned in Namibia from September

Yahoo News 21 Aug 08;

Namibia will impose a ban on all trade with 'worked ivory' from next month in a bid to assert its control and abide by international regulations on endangered species, an official said on Wednesday.

"We have to strengthen control measures in ivory trade to abide by provisions of the Convention In Trade International Trade in Endangered Species (CITES), which requires specific legislation," Kalumbi Shangula told reporters.

"And until that is in place, dealing in ivory products...will be prohibited," said Shangula, a permanent secretary in the environment and tourism industry.

The temporary ban includes sale of ivory jewellery until a new law is in place to control such trade, Shangula said.

"The temporary moratorium will start on September 1 until the Controlled Wildlife Products Bill is enacted," he said, adding that the bill would be tabled in parliament in September.

Back in 2004, CITES recognised traditional carved ornamental ivory products called 'ekipas', worn by women of the Oukwanyama ethnic group in northern Namibia, as cultural objects.

They were allowed to be sold within the country as personal effects.

The planned ban also affects 'ekipas', Shangula said.

Windhoek jeweller Horst Knop welcomed the move but said jewellers and goldsmiths would lose income.

"This is a very short notice, just 11 days before the ban comes into effect, but in principle it is a good thing, although we cannot sell ivory jewellery already on our shelves for a while.", he said.

Health risk for Ghana children from electronic goods recycling

The Telegraph 20 Aug 08;

Children are putting their health at risk salvaging metals from unwanted electronic equipment being dumped in west Africa.

Containers full of e-waste arrive by ship from Europe, North America and Japan and find their way onto dumps such as this one in Agbogbloshie market in Ghana's capital Accra.

Electronic goods are stripped down and sold for parts and then discarded. Children - desperate to raise money for school fees or to help support their families - then raid them for any remaining pieces of copper or aluminium in cables and motors.

To get at the metals the plastic casing is burned off releasing toxins in plumes of black smoke.

A recent investigation by a Greenpeace science team found that the waste is poisoning the environment. Analysis of soil and sediment revealed that it was contaminated with hazardous chemicals.

Some of the samples contained toxic metals including lead in quantities as much as 100 times above levels found in uncontaminated soil and sediment samples.

Other chemicals such as phthalates, some which are known to interfere with sexual reproduction, were found in most of the test samples. One sample also contained a high level of chlorinated dioxins, known to promote cancer.

"Many of the chemicals released are highly toxic, some may affect children's developing reproductive systems, while other can affect brain development and the nervous system," said Dr Kevin Brigden of Greenpeace International.

Greenpeace said containers full of old and often broken computers, monitors and TVs from many household brands arrive in Ghana from Germany, Korea, Switzerland and the Netherlands falsely labelled "second-hand goods" where they end up in scrapyards or dumps.

Workers and children use their bare hands salvaging parts where they are exposed to toxic fumes and dust.

The crude recycling is mainly for aluminium and copper which sells for approximately $2 per five kilos.

Martin Hojsik, Greenpeace international toxics campaigner, said: "Unless companies eliminate all hazardous chemicals from their electronic products and take responsibility for the entire lifecycle of their products, this poisonous dumping will continue.

"Electronics companies must not allow their products to end up poisoning the poor around the world."

Water everywhere, and not a drop to grow

Colin Chartres, BBC Green Room 20 Aug 08;

Limited availability of fresh water is often overlooked as a cause of food scarcity and environmental decline, according to Colin Chartres. Governments should be ramping up efforts to make sure we have enough to grow crops as well as enough to drink, he argues.

This year, the world and, in particular, developing countries and the poor have been hit by both food and energy crises.

As a consequence, prices for many staple foods have risen by up to 100%.

When we examine the causes of the food crisis, there are many contributing factors: a growing population, changes in trade patterns, urbanisation, dietary habits, biofuel production, climate change and regional droughts.

Thus, we have a classic increase in prices as a result of high demand and low supply. However, few commentators specifically mention the declining availability of water that is needed to grow irrigated and rain-fed crops.

According to some, the often mooted solution to the food crisis lies in plant breeding that produces the ultimate high yielding, low water-consuming crops.

While this solution is important, it will fail unless attention is paid to where the water for all the food, fibre and energy crops is going to come from.

Thirsty world

The causes of water scarcity are essentially identical to those of the food crisis.

There are serious and extremely worrying factors that indicate water supplies are close to exhaustion in some countries.

Population growth over the next four decades will see the number of people in the world increase from 6.5 billion up to 9.0 billion.

Essentially, every calorie of food requires a litre of water to produce it.

So on average, we require between 2,000 and 3,000 litres of water per person to sustain our daily food requirements.

We will have 2.5 billion extra mouths to feed by 2050, so finding the extra water each year will not be an easy task, given that it is more than double what is currently used in irrigation.

We also have to bear in mind that the availability of new fertile land in humid areas for rain-fed farming is extremely limited.

Recent studies, as part of the Comprehensive Assessment of Water Management in Agriculture, have indicated that we will not be able to produce all the food, feed and fibre required in 2050 unless we improve the way we manage water.

Invest and survive

A few years ago, the International Water Management Institute (IWMI) demonstrated that many countries are facing severe water scarcity, either as a result of a lack of available freshwater, or as a consequence of a lack of investment in infrastructure such as dams and reservoirs.



What makes matters worse is that this scarcity predominantly affects developing countries where the majority of the world's 840 million undernourished people live.

However, there are potential solutions. These include more water storage, improved management of irrigation systems and increasing water productivity in irrigated and rain-fed farming systems.

All of these will require investment in knowledge, infrastructure and human capacity.

Better water storage has to be considered. Ethiopia, which is typical of many sub-Saharan African countries, has a storage capacity of 38 cubic metres per person.

In contrast, Australia has almost 5,000 cubic metres per person, an amount that in the face of current climate change impacts may be inadequate.

Whilst there will be a need for new large and medium-sized dams to deal with this critical lack of storage in Africa, other simpler solutions will also be part of the equation.

These include the construction of small reservoirs, sustainable use of groundwater systems including artificial groundwater recharge, and rainwater harvesting for smallholder vegetable gardens.

Improved year-round access to water will help farmers maintain their own food security using simple supplementary irrigation techniques.

The redesign of both the physical and institutional arrangements of some large and often dysfunctional irrigation schemes will also bring the required productivity increases.

Safe, risk-free re-use of wastewater from growing cities will also be needed.

Of course, these actions need to be paralleled by development of drought-tolerant crops, and the provision of infrastructure and facilities to get fresh food to markets.

Resource competition

Since the formulation of the UN Millennium Development Goals (MDGs), much of the water agenda has been focused around the provision of drinking water and sanitation.

This puts demand on the same resources as agricultural water; and as we urbanise and improve living standards, increasing competition for drinking water from domestic and other urban users will put agriculture under further pressure.

While improving drinking water and sanitation is vital with respect to health and living standards, we cannot afford to neglect the provision and improved productivity of water for agriculture.

Current estimates indicate that we will not have enough water to feed ourselves in 40 years time, by when the current food crisis may turn into a perpetual crisis.

Just as in other areas of agricultural research and development, investment in the provision and better management of water resources has declined steadily since the Green Revolution.

My water science colleagues and I are raising a warning flag that significant investment in both research and development and water infrastructure development is needed if dire consequences are to be avoided.

UK citizens using 58 baths of water a day

WWF website 20 Aug 08;

While each person in the UK drinks, hoses, flushes and washes their way through around 150 litres of mains water a day, they consume about 30 times as much in “virtual” water embedded in food, clothes and other items – the equivalent of about 58 bathtubs full of water every day.

Launching the report, UK Water Footprint: the impact of the UK’s food and fibre consumption on global water resources, at World Water Week in Stockholm today, Stuart Orr, WWF-UK’s water footprint expert, said the UK was the sixth largest importer of water in the world.

“Only 38 per cent of the UK’s total water use comes from its own rivers, lakes and groundwater reserves,” he said. “The rest is taken from water bodies in many countries across the world to irrigate and process food and fibre crops that people in Britain subsequently consume

“What’s particularly worrying is that huge amounts of these products are grown in drier areas of the world where water resources are either already stressed or very likely to become so in the near future.”

Just one tomato from Morocco takes 13 litres of water to grow while the various ingredients in a cup of coffee collectively use 140 litres. A shirt made from cotton grown in Pakistan or Uzbekistan cotton – and possibly irrigated by water from the Indus river or the rivers that feed the Aral Sea in central Asia – soaks up 2,700 litres of water.

Cotton producing Pakistan has recently experienced its lowest water availability on record and the Indus river often runs dry before it reaches the sea. This affects the communities and critical habitats in the Indus delta as well as endangered species such as the Indus river dolphin. Over abstraction from the rivers that flow into the Aral Sea for the irrigation of cotton fields has led to the loss of 60% of its area and 80% of its volume in the last 40 years.

Closer to home, Spanish oranges and grapes come from a country where, earlier this year, drinking water has been shipped in from France due to acute shortages.

“Most people aren’t even aware that it takes massive amounts of water to grow the food and fibres we consume on top of what is used for drinking and washing and watering the lawn,” Mr Orr said.

”Therefore, it is essential that business and government identify the areas that could potentially suffer water crises and develop solutions so the environment is not overexploited to the point that people and wildlife lose out.”

WWF is encouraging some of the UK’s largest companies, such as Marks and Spencer, to evaluate their water footprints. A water footprint assesses the amount of water a business uses both directly from the tap and virtually through its supply chain. It includes water taken from both UK rivers and aquifers and those in other countries where crops are grown and processed.

WWF also asks companies to promote sustainable water use in areas where water is scarce.

“The private sector has a very important role to play. It can engage with governments and communities along its supply chain to support better water management,” Mr Orr said. “In order to reduce risk, businesses need to do their utmost to encourage more efficient and effective water use in water stressed areas where they operate.”

In India and Pakistan, WWF is working with farmers who grow thirsty crops such as cotton, rice and sugar cane to explore ways in which farmers can use less water to grow more crops. In one sugar cane trial, agricultural water use has dropped by 40 per cent while yields have risen by a third.

“This is not just an issue for food and clothing companies, producers and retailers. Insurers and investors have a vested interest in encouraging efficiency of water use and security of water supply in an ever thirstier world. Water is irreplaceable and climate change and population growth are only going to exacerbate the problem,” said Mr Orr.

He added: “There’s an important role for the public here. As a consumer you can ask businesses, including your local supermarkets, to tell you what they are doing to ensure good water management along their supply chains. As a citizen you can urge your government to make good water management a priority both in this country and overseas. But if we do nothing to alleviate the acute pressures on water resources at home and abroad then our inaction could have far reaching consequences for people and habitats.”

Call to tackle UK business waste

Richard Black, BBC News 20 Aug 08;

The government needs to step up efforts to reduce waste from business, according to a parliamentary committee.

The House of Lords Science and Technology Committee recommends using variable VAT rates to cut unsustainable consumption of raw materials.

Its report says pressure has so far concentrated on householders, who account for only 9% of the UK's waste.

Environment minister Joan Ruddock said the government does have measures that are inducing businesses to cut waste.

Those measures include the landfill tax escalator under which the tax on landfill will rise by £8 per tonne each year until 2011.

The committee acknowledged that this had been effective in reducing the amount of waste dumped in landfill sites, but said other initiatives were needed.

"We would like to see the VAT regime reformed so that products that have a long life-cycle, or can be easily and cheaply repaired rather than replaced, are made economically more attractive," said Lord O'Neill, who chaired the sub-committee on waste.

"This would be an important step in turning away from the 'throwaway' consumer culture we currently have."

'Disappointing' cuts

About one-third of the UK's waste is produced by construction and demolition, and a further third by mining and quarrying.

Nevertheless, the committee says, government action and media attention have concentrated on the much smaller contribution from households.

Councils too should change focus, it recommends, to prioritise reducing waste from businesses.



Some business leaders interviewed by the committee said each company should be made responsible for the waste associated with its own products, a recommendation that the committee endorsed.

Lord O'Neill said this would ensure that "manufacturers who behave irresponsibly face financial consequences and those who are doing the right thing are supported."

Another recommendation is that the government should ring-fence a proportion of revenue raised from the landfill tax for agencies charged with reducing business waste.

Envirowise and the Waste and the Resources Action Programme (Wrap) are among the agencies whose budgets are being cut - a move about which the committee expresses "extreme disappointment".

The committee also refers to an issue often expressed by environmentalists - that the advice that people receive in the UK focuses too much on recycling, and not enough on reducing consumption.

The argument is that policies should aim first at reducing what people use, then encourage re-use, and only then stimulate recycling.

"If our society was to implement the hierarchy effectively, a far smaller amount of waste would need to be disposed of after all the previous stages had been put into practice," the committee concludes.

This Year So Far Coolest For at Least 5 Years - WMO

LONDON - The first half of 2008 was the coolest for at least five years, the World Meteorological Organisation (WMO) said on Wednesday.

The whole year will almost certainly be cooler than recent years, although temperatures remain above the historical average.

Global temperatures vary annually according to natural cycles. For example, they are driven by shifting ocean currents, and dips do not undermine the case that man-made greenhouse gas emissions are causing long-term global warming, climate scientists say.

Chillier weather this year is partly because of a global weather pattern called La Nina that follows a periodic warming effect called El Nino.

"We can expect with high probability this year will be cooler than the previous five years," said Omar Baddour, responsible for climate data and monitoring at the WMO.

"Definitely the La Nina should have had an effect, how much we cannot say."

"Up to July 2008, this year has been cooler than the previous five years at least. It still looks like it's warmer than average," added Baddour.

The global mean temperature to end-July was 0.28 degrees Celsius above the 1961-1990 average, the UK-based MetOffice Hadley Centre for climate change research said on Wednesday. That would make the first half of 2008 the coolest since 2000.

"Of course at the begining of the year there was La Nina, and that would have had the effect of suppressing temperatures somewhat as well," Met Office meteorologist John Hammond said.

"But actually La Nina is showing signs of moving towards a more neutral state."

The weakening of the La Nina effect over the last few months could see the global mean temperature creep up again in the latter part of the year, he added.

The past decade ending in 2007 was the hottest since reliable records began around 1850, according to the WMO. World temperatures are about 0.74 Celsius (1.2 F) higher than a century ago.

The UN Intergovernmental Panel on Climate Change (IPCC), a group of hundreds of scientists, last year said global warming was "unequivocal" and that manmade greenhouse gas emissions were very likely part of the problem.

The WMO releases its final figures for global temperature and ranking for 2008 in December.

Gas hydrate: The next big fuel source?

Michael Richardson, Straits Times 21 Aug 08;

ICE that burns? It sounds like a magician's trick. So do some of the exotic names given to gas hydrate - 'flammable sorbet', 'crystal gas' and 'burning ice'. But recent scientific surveys and test drilling in Asia and elsewhere have proven that this substance exists in massive, potentially recoverable quantities and that it could be an important commercial energy source for the future.

Indeed, some of the world's biggest economies and energy users - including the United States, Japan, China, India, South Korea and Canada - are racing to develop production techniques and equipment to tap gas hydrate and bring it to market within the next decade. For all of them, except energy self-sufficient Canada, the ability to tap new domestic sources of natural gas offers the prospect of substantially reducing dependence on expensive gas imports.

Hydrate deposits up to several hundred metres thick are generally found in two places: on or beneath the deep ocean floor, or underground, close to the Arctic permafrost layer where high pressure and cold temperatures turn natural gas (methane, ethane and propane) into a semi-solid form.

Gas hydrate looks like ordinary ice, although it is sometimes discoloured. But when brought to the surface and allowed to warm, it can be lit with a match. It then burns with a soft orange flame. One cubic metre of gas hydrate releases as much as 164 cubic metres of natural gas, in which methane is usually the chief constituent.

While global estimates vary considerably, the US government's energy department says that the energy content of methane in hydrate form is 'immense, possibly exceeding the combined energy content of all other known fossil fuels', meaning coal, oil and conventional gas.

The presence of hydrates has been inferred from seismic surveys and sub-sea sampling along most of the world's continental shelf margins. Some of the biggest deposits found so far are on the ocean floor off Japan, South Korea, India and China, and on and off US and Canadian Arctic land territory.

The Japanese government announced last year that there were over 1.1 trillion cubic metres of methane hydrates in a Pacific Ocean trench called the Nankai Trough, some 50km from the coast of Honshu, the main Japanese island. This reserve is equivalent to 14 years of Japan's gas use. The country currently imports nearly all the oil, gas and coal needed to run its vast economy, the world's second largest after the US'.

Three years ago, the Japanese government said that the commercial exploitation of methane hydrate was economically viable. Oil was US$54 a barrel then, less than half its present price.

In November last year, the South Korean government said that it had found enough gas hydrate in the sea between South Korea and Japan to meet 30 years of demand. Six months earlier, China announced that it had, for the first time, managed to tap into seabed sediment containing gas hydrate in the northern part of the South China Sea. Initial estimates indicated that the find contained the equivalent of more than 100 million tonnes of oil - about one-third of China's annual oil consumption.

China was the fourth country after the US, Japan and India to achieve this technological breakthrough in the deep-sea search for energy. India announced in 2006 that it had made several huge discoveries of gas hydrate off its east and west coasts.

Since last April, the US has signed separate agreements with India, South Korea and Japan to cooperate in hydrate research, exploration and production. Japan, the US and Canada, working in close collaboration, have achieved several days of continuous extraction of methane from underground hydrate reserves in the Arctic permafrost. Large-scale production tests are planned in the Canadian Arctic this winter and in the US Arctic next year.

Test production from offshore Arctic finds is expected to lag by three to five years, because marine deposits are less well documented than those on land. Sea sampling and drilling are also much more expensive. Japan has said it hopes to start test drilling in the Nankai Trough next year, leading to commercial production by 2016. Korea has a similar production timetable.

However, apart from the high costs and technical challenge, all the hydrate explorers face another possible danger - environmental disaster. While governments are attracted to abundant clean fuel, scientists are concerned about drilling risks that disturb the seabed and trigger an uncontrolled release of methane, a potent greenhouse gas.

The British government's former chief scientific adviser, Sir David King, warned recently that one big unknown about global warming is the stage at which dangerous tipping points may be reached that lead to runaway heating of the planet. He cited as an example the release of methane hydrate deposits in the Arctic.

Some evidence suggests that a catastrophic release of methane from the ocean 55 million years ago, possibly caused by undersea volcanic explosions and landslides, was responsible for making the earth much warmer.

The modern hydrate quest is built on a paradox. When released to the air, methane is a greenhouse gas that traps around 20 times more solar heat in the earth's atmosphere than carbon dioxide, the main global warming gas.

However, when burned, methane releases up to 25 per cent less carbon dioxide than combustion of the same amount of coal. It also emits no nitrogen and sulphur oxides, the gases that harm human health when coal is burned without effective filters.

The world's abundant methane hydrate deposits have been safely stored for thousands of years in the ocean depths and Arctic permafrost. Those who now seek to exploit what is probably the world's greatest reserve of new fossil fuel must therefore be sure that in doing so they improve, not harm, the global environment.

Australian "Hot Rocks" Offer 26,000 Yrs of Power

Michael Perry, PlanetArk 21 Aug 08;

SYDNEY - Barely one percent of Australia's untapped geothermal energy could produce 26,000 years worth of clean electricity, scientists said, as the government announced a a A$50 million (US$43 million) project to help develop the technology.

Australia is the world's biggest coal exporter with coal used to generate about 77 percent of its electricity. Its reliance on coal for generating electricity makes it the world's biggest per-person polluter, with five times more emissions per head than China.

"Geothermal energy which is sometimes known as hot rocks has got a huge potential for Australia, both as a solution to climate change and in terms of national energy security," said Resource Minister Martin Ferguson.

To produce power from geothermal energy, water is pumped below ground where it is heated and the heat energy used to generate power.

Geoscience Australia has mapped the nation's geothermal energy, using temperature recordings from decades of drilling by energy and exploration firms, sometimes to a depth of five kms (three miles).

A total of 5,722 petroleum and mineral boreholes across Australia were used to generate the map.

"One percent of reserves would produce 26,000 years of energy supplies," Geoscience's Anthony Budd told Reuters on Wednesday.

Budd said "hot rocks" needed to be 150 degrees Celsius to produce electricity, which was achievable at a depth of one to five kms, noting temperature rose deeper into the earth's crust.

An Australian Geothermal Energy Association report this week forecast it could potentially produce 2,200 megawatts of baseload power by 2020, adding that represented up to 40 percent of Australia's 2020 renewable energy target.

The association estimated A$12 billion would need to be invested to develop the 2,200 megawatts of power, but added the cost of generating electricity would fall to acceptable levels by the time commercial projects were up and running.

It estimated it would cost A$120 per megawatt hour from a small pilot plant producing 10 to 50 megawatts of power, and A$80 per megawatt hour for a large scale plant of 300 megawatts or greater.

"The upper cost boundary will decline over time because the level of uncertainty is expected to narrow as the industry grows. This cost is expected to be lowest cost of any form of renewable or low emissions energy," it said.

The government's geothermal drilling project will see different technologies used at various locations around Australia to try and determine the best technology for converting "hot rock" energy into electricity.

Ferguson said the first commercially viable geothermal power plants could be in place within four to five years.

"Geothermal energy provides clean base-load power and is potentially a very important contributor to Australia's energy mix in a carbon-constrained world," he said.

Prime Minister Kevin Rudd won power last November in part by promising to sign the Kyoto Protocol, which sets binding limits on emissions from developed countries, and to cut emissions by 60 percent of 2000 levels by 2050. (US$1=A$1.15) (Editing by Sanjeev Miglani)
