Whale of a bad idea

Letter from Satveer Kaur (Ms), Straits Times 3 Sep 08;

I REFER to last Friday's article 'Whale sharks at IR? Bad move, say activists' about Resorts World at Sentosa (RWS) bringing in a whale shark to the integrated resort (IR).

This is really appalling.

How can they for even a moment think they can provide a suitable environment for what is the largest fish in the world?

All the love and care they claim they will provide to the shark will never be enough to meet its needs.

Will they allow it to swim and dive the great distances it does in the wild?

Whale sharks have been tracked over 13,000km and dive to depths of more than 1,000m.

Even if we place the whale shark in a tank the size of Singapore it would not be big enough. What more on a tiny part of Sentosa?

Furthermore, it is strange that RWS has cited their Marine Life Fund as a way to underline its commitment to conservation.

While this should be applauded, it does not in any way make up for their disregard for the welfare of the animals under their charge.

This shark has the world's oceans as its natural home, please do not confine it to a tank for the rest of its life.

Development of NTUC Club's S$45m Palawan Resort at Sentosa delayed

Imelda Saad, Channel NewsAsia 2 Sep 08;

Touted as the Singapore labour movement's first high-end resort for the working class, the S$45-million Palawan Beach Resort has been facing major delays.

The proposed 200-room resort, announced 3 years ago by then NTUC Secretary-General Lim Boon Heng, was to have been built on a 3-hectare plot of land, next to Palawan Beach at Sentosa , and to have opened its doors by March this year.

According to the Sentosa Master Plan, the site is zoned for Sports and Recreation use.

Channel NewsAsia understands that based on the concept for the site, the cost of leasing the land now has gone up considerably compared with initial estimates.

Other reasons cited for the delay include the skyrocketing costs of construction and material.

Construction costs in Singapore have gone up some 60 to 70 percent since 2005, and in the past 12 months alone, it has increased by almost 30 percent.

Based on the condominium plots at Sentosa Cove, the land value on Sentosa has risen between 3 and 3.7 times since 2005.

Nicholas Mak, director of Knight Frank, a real estate consultancy firm, said: "All the land on Sentosa are practically state land so the government will have to weigh the balance on whether to maximise the value of the state land by selling it at the highest possible price, or should they be selling some parcels of state land to certain organisations that may be developing a project that meets certain social needs, like for example the NTUC."

He added that the S$45 million budgeted for Palawan Beach Resort may now not be enough for the plans that were laid out.

A report by the labour movement's recreational arm said Palawan Beach Resort will boast state of the art facilities, including a luxurious spa and a mirage pool. Room rates were expected to average S$150, with discounts for union members.

However, to ensure the project is financially sustainable, the concept and business model are being reviewed. Areas being looked into include reducing the number of facilities at the resort, the room size or even the number of rooms.

Both NTUC Club and landlord Sentosa Development Corporation declined to be interviewed, although NTUC Club confirmed that talks between both parties are ongoing.

In a statement to Channel NewsAsia, it said the resort will serve its social mission of providing affordable social and recreational facilities, in a sustainable manner.

General-secretary of the Metal Industry Workers Union, Tan Chai Kun, said he is looking forward to the new resort and their members, especially those in the lower-income group, enjoying higher-end recreational facilities.

NTUC Club hopes to put the final touches on the project's concept by the end of the year and obtain the approval from authorities.

NTUC Club is the biggest local resort operator, managing three budget family-themed resorts, with two resorts located at Pasir Ris and one located at Sentosa .

'Green' meetings take off here

More firms ask hotels, convention centres for eco-friendly measures
Tessa Wong, Straits Times 3 Sep 08;

WHEN local think-tank the Singapore Institute of International Affairs (SIIA) organised a conference earlier this month at the Regent Hotel, it made a few unusual requests.

The firm asked for sugar in bowls, not sachets. It wanted milk and water in jugs, instead of single-serve plastic containers. And it had the hotel bump up the thermostat by a few degrees.

Environmentally friendly requests like these are becoming increasingly common in Singapore and abroad as more companies start holding 'green meetings'.

A check with several local hotels and convention centres revealed that demand for eco-friendly conferences has snowballed during the last three years.

Companies are asking for things like recycled notepads and natural lighting while cutting back on buffet lunches and catered snacks.

The Grand Copthorne Waterfront saw about 30 requests for green meetings last year, and has already seen 50 this year. Suntec City, meanwhile, will host 10 such meetings this year, up from five last year. The Royal Plaza at Scotts has also received 10 bookings this year.

'(They) make good business sense as they save money in the long term by conserving resources,' said Mr Aloysius Arlando, an assistant chief executive at the Singapore Tourism Board (STB).

The trend is already well-established in the United States, Australia and Europe. It has been earmarked by trade journals as one of the top fads in the meetings, incentives, conventions and exhibitions, or Mice, sector.

Companies say the explosion of green meetings is the result of companies incorporating eco-friendly ideas into their social responsibility policies. At the same time, going green can save firms big bucks, especially during large gatherings.

A USA Today report in April said an American company saved US$50,000 (S$70,700) for a 3,500-person event by providing water coolers instead of bottled water.

Eco-friendly meeting policies can save a profound amount of trash as well.

Following a convention organised by McDonald's in April, everything from paper to the carpet used in trade booths was recycled. That kept 244,000kg of rubbish from landfills.

But do such efforts make a difference? Mr Lee Eng Lock of Trane, an energy solutions firm, does not think so. 'I think it's part of corporate social responsibility and that everyone has to be seen to be getting on the bandwagon.'

He called the green meeting trend 'cosmetic' and said few companies take substantial steps like cutting back on their energy and water use. 'I hope people focus on the bigger picture. You have to do substantive things, or else nothing will change.'

Organisations remain optimistic that it will make a difference.

'We practise what we preach, and we believe everyone has to play a role for the environment,' said Mr Anndy Lian, communications manager of SIIA.

'This is not something that can be changed overnight, but people need to know the importance of going green.'

Meanwhile, at least one Asian conference organiser has embraced this trend. The Thailand Convention and Exhibition Bureau launched a two-year green meeting campaign among local operators earlier this year.

When asked if it had similar plans, Mr Arlando said STB will continue to work on 'intensifying our collective efforts with industry partners and sister agencies' to ensure Singapore is a prime destination for meetings and conferences.

Indonesian raids on tiger traffickers yielding arrests in Sumatra

mongabay.com 2 Sep 08;

A raid on illegal tiger traders in Indonesia resulted in four arrests in Sumatra, reports the Wildlife Conservation Society (WCS).

The arrests come under a new crack-down by Indonesian authorities on the sales of tiger parts. 10 traffickers have been arrested in the past 3 months.

The Indonesian Government is committed and to stopping illegal wildlife trade and strengthening its commitments to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

We are seeking to put a stop to the capture, possession and trade of protected wildlife in Indonesia" Said Djati Wicaksono, Head of the PHKA Office of Natural Resource Conservation in Medan, who led the raid.

Tigers are critically endangered in Indonesia due to habitat loss, killing as vermin, and poaching for their parts, which are used in traditional medicine and sold as souvenirs. Fewer than 1,000 individual tigers are left in Sumatra and two subspecies — the Bali tiger (Panthera tigris balica) and the Java tiger (Panthera tigris sondaica) — have already been driven to extinction.

"Tiger poaching and trade is a massive threat to the survival of this iconic animal," said Dr Noviar Andayani, Director of the WCS Indonesia Program which helped establish the program that investigates and prosecutes wildlife crimes. "The long-term survival of this species will require effective action to control illegal poaching, to reduce habitat loss, and to prevent conflict between tigers and local people."

"While the threat of extinction of tigers is often talked about, preventing this from happening requires real action on the ground such as we are seeing in Indonesia now," he continued. "In the areas of Sumatra where we have worked hardest and longest we are starting to see indications that the tiger population is finally recovering."

Environment needs dose of bold reform

Joy Hyvarinen, BBC Green Room 2 Sep 08;

Reform of the way the UN handles environmental issues is badly needed, argues Joy Hyvarinen. However, she says, governments may be getting mired in a fruitless dispute that will leave the basic flaws untouched.

The EU and the US are at loggerheads again in the international environmental arena.

After years of disagreement about climate change, the issue now is whether the UN's environment programme should become a fully-fledged organisation, with more power, money and autonomy.

The international organisations that look after the global environment need reform, but arguing about the institutional format for the UN's main environmental body is not necessarily going to help resolve the problems.

The first thing to understand is that the UN's environment programme is not the only UN body that concerns itself with the environment - far from it.

Scores of UN organisations, agreements and programmes tackle environmental issues.



For example, a tropical forest country that wants to have a say in international decisions about forests should be attending meetings of the Rome-based UN Food and Agriculture Organization, the UN forest forum in New York, the Montreal-based global agreement to protect natural diversity, and the annual climate change meetings, to name a few.

A major problem with international environmental decision-making is that the various UN bodies are not joined up. Priorities are unclear and there is much overlap and duplication of work.

Another problem has been an explosion of new multilateral environmental agreements (MEAs), put in place to deal with the increasing problems that require international cooperation.

There are currently more than 500 of them.

International treaty meetings are very complex. For example, the main UN treaty to protect species and ecosystems can require specialist knowledge of issues ranging from shrimp farming and desertification to intellectual property rights and the legal regime for marine life on the deep sea bed, at a single meeting.

Government representatives spend an enormous amount of time at international conferences about issues such as climate change, biodiversity, desertification and wildlife.

A huge number of decisions and recommendations emerge from these meetings; but few will ever be read by those who are supposed to put them in practice on the ground.

Compulsory cash

Developing countries in particular are struggling with implementation, lack of financial assistance from the international community and the many reporting obligations under various MEAs.

Implementation raises an important question about international diplomatic decision-making and in-country realities.



The discussions about strengthening international environmental organisations and agreements are taking place at UN headquarters in New York.

It is hard to see how lessons from the ground on what actually works - and what doesn't - can find their way into these discussions.

Now, a new debate threatens to distract attention from the real needs for reform.

The EU wants a UN Environmental Organisation ("UNEO"), which would mean turning the UN Environment Programme (Unep) into a freestanding agency, with its own budget.

The EU's proposal is backed by a group of about 50 countries called "Friends of a UN Environmental Organisation". The US opposes the proposal.

Would a UNEO be more effective than Unep in stemming the rising tide of environmental destruction?

Maybe; but no institutional format will ensure good environmental decision-making, unless the political will is there.

The UNEO would not depend on voluntary funding, as Unep does, which could make a difference; but the EU has not yet presented detailed proposals, making it difficult to assess what the added value of an UNEO would be.

However, it is essential to tackle the problems in the international decision-making architecture for environment. The system of organisations and agreements that we have now is not effective enough to deal with the world's escalating environmental problems.

Stale argument

There is a need to move beyond the stalemate about whether Unep should become a UNEO, with imaginative proposals that make the best of the existing structure and fill institutional gaps where needed.



Following the UN's 60th anniversary in 2005, the UN ambassadors from Mexico and Switzerland have been leading discussions with other government representatives in New York about how to strengthen international environmental organisations and agreements.

Last year the ambassadors presented a set of "building blocks" for further discussion.

The building blocks are issues which governments agree need to be tackled to make international decision-making work better: strengthened scientific assessments, better monitoring and early warning capacity, closer co-ordination and co-operation among UN agencies, and financial assistance to developing countries.

Progress has been slow. One issue to be decided now is whether the discussions (referred to as "informal consultations") could move into negotiations, ie actually making decisions about what should be done to improve international organisations and institutions.

Even if the discussions become negotiations, the Swiss and Mexican ambassadors have noted that the time is not right for decisions about major changes, because states have such different views. The task of the ambassadors is not one to be envied.

Ambitious needs

Looking at the state of the world's environment, business as usual is not an option. It is time for decisive action to improve international organisations and decision-making.

The world needs UN organisations that are set up so that they can deal effectively with our current problems, monitor the state of the world environment and respond to new threats, and take the lead in ensuring that countries do their bit.

Last year the UN ambassadors identified "ambitious incrementalism" as a guiding principle for the discussions in New York.

This diplomatic-speak is intended to reflect lofty long-term aims, based on a step-by-step approach, while taking into account that governments do not agree on what the long-term aims should be.

This year, the ambassadors stated that "as for ambitious incrementalism, they now hope to move with speedy circumspection".

Nice turns of phrase, but they risk describing plain old business as usual. Perhaps what is needed now is something like "courageous reform".

The bottom line is that nothing will change without greater political will and unless rich countries provide more funding to tackle international environmental issues.

Without that, restructuring the international environmental decision-making architecture will simply be a diversion.

4,000+ Japan Whale Harvest Not Justified, Experts Say

Ker Than, National Geographic News 2 Sep 08;

A new study by Japan's national whale-research program is drawing sharp rebuke from scientists and conservationists who say the results did not necessitate killing more than 4,000 whales.

Critics have long accused Japan of using its scientific whaling program to circumvent a 1986 moratorium on commercial whaling by the International Whaling Commission (IWC).

In the new research, Kenji Konishi of Japan's Institute of Cetacean Research and his colleagues analyzed data from 4,704 Antarctic minke whales killed by the Japanese Whale Research Program (JARPA) from 1987 to 2005.

They concluded that the thickness of the whales' blubber decreased by 3.6 millimeters (0.14 inch), or about 9 percent, during the 18-year period.

The Japanese team suggests the thinning blubber may be due to either global warming-related reductions in ocean krill populations, competition by other whale species, or a combination of the two factors.

The study is detailed online in a recent edition of the journal Polar Biology.

"Crude" and Unnecessary

Konishi said killing the whales was the only way to ensure the measurements of the blubber's thickness were consistent across the different specimens.

"These data could only be obtained using lethal research," Konishi told National Geographic News.

Previous studies using biopsy samples, which are taken from living whales, have not obtained "total fat contents and thus energy content" of the animals' blubber, Konishi added.

Scott Baker, associate director of the Marine Mammal Institute at Oregon State University, was not involved in the study.

Baker said biopsies and other nonlethal methods such as genetic and photographic identification would have been adequate for gauging the health of the whales and their food availability.

Baker called JARPA's methods of killing the whales—which included exploding harpoons and large-caliber rifles in case death was not instantaneous—"crude" and ultimately unnecessary.

Baker also questioned the biological significance of the blubber reduction reported by the Japanese team.

"This is a very small biological effect," Baker said. The change in blubber thickness was "9 percent over 18 years. That's half a percent a year."

Doubts about the scientific usefulness of the study were echoed by Stephen Palumbi, a marine ecologist at Stanford University.

"All their analysis can show is that minke whales might be getting slightly thinner," Palumbi said. "Is it biologically meaningful? It's not clear."

Palumbi called the team's hypothesis that minke whales are losing weight as a result of reduced krill in the oceans a "huge leap."

Their results show "a statistical correlation but does not reveal anything about cause," Palumbi said.

Contradictory Results

A joint statement issued by Greenpeace and the International Fund for Animal Welfare (IFAW) said the study's findings contradict previous JARPA research that suggested minke whales were benefiting from a krill surplus created by the elimination of other large whales by human hunting.

"Japan can't have it both ways," the statement reads. "The minkes can't be reaching maturity faster because they are feasting on surplus krill while at the same time losing weight."

IFAW program manager Beth Allgood expressed concern that the new study could be used to vindicate Japan's scientific whaling program at a planned meeting of the IWC later this month.

"This paper cannot be used as evidence that scientific whaling has resulted in legitimate research until the larger community reviews its methodology, statistical rigor, and whether it is ethically justifiable to kill minke whales for results like these," Allgood said.

(Read related story: "Japan May Be Ready to Deal on Whaling, Insider Hints" [March 26, 2008].)

Critics also say they are troubled by the study's suggestion that other whale species such as humpback and fin whales are outcompeting minke whales for krill.

"As far as I know, there isn't any evidence of that anywhere," Palumbi said. "If you were a conspiracy theorist, you might say this is set up to be that evidence."

Japanese researchers recently reported that humpback whales have begun encroaching upon the territories of minke whales.

The hypothesis is similar to one proposed by Japanese whale researchers in the mid-1990s that endangered blue whale populations were having trouble recovering because minke whales were outcompeting them for krill, Baker said.

"They said at the time that they needed to conduct scientific research to determine this," Baker said. "What was that scientific research? Killing minke whales."

Whalers in Norway defend castigated hunt

Pierre-Henry Deshayes, Yahoo News 2 Sep 08;

In the Lofoten Islands, the main base for Norway's whaling industry, whalers adamantly defend the harshly criticised practice and reject claims that consumers are not buying whale meat.

In this cluster of islands nestled above the Arctic circle, the hunting season is over for this year. The whalers have all returned to their home ports, their vessels easily identified by the harpoons perched on the bow and an imposing watchtower that enables them to spot minke whales from afar.

The quota was hard to fulfill again this year, with whalers killing only half of the allowed catch of 1,052 whales. Since Norway resumed whaling in 1993, seven years after an international moratorium came into force, the hunters have only met their quota once.

They blame the low catch on the high fuel price, bad weather -- still waters are needed to harpoon a whale -- as well as quotas often distributed in regions far out to sea and a crunch in processing and distribution channels.

Greenpeace sees the issue differently.

"The figures speak for themselves: the market for whale meat is non-existent," says Truls Gulowsen of the environmental group's Norwegian branch.

Greenpeace long ago abandoned its spectacular anti-whaling campaigns where its boats went head to head in confrontations with whaling vessels.

"We have a better plan: we'll let the market decide. And it will die out," Gulowsen says.

Once a staple of the poor man's diet, whale meat is now almost never found in grocery stores.

But in Svolvaer, a small village in the Lofoten Islands, it has pride of place on restaurant menus where it is served both fried and as carpaccio, often a pleasant surprise for tourists' sceptical palates.

"Our problem is ignorance. A lot of people just don't understand what it is they're opposed to," says Leif Einar Karlsen, a local whaler who left his job as a mechanic 12 years ago to start hunting.

"People don't know that there are dozens of kinds of whales," he adds.

Stocks of minke whale, the smallest of the big whales, number more than 100,000 in the North Atlantic.

Norway, together with Iceland the only countries to authorise commercial whaling, estimates that the stocks are abundant enough to allow a limited quota.

But the minke whale remains on the list of near-threatened species drawn up by UN agency CITES (Convention on International Trade in Endangered Species), which means it cannot be sold internationally.

"The result of unfortunate and effective lobbying," laments Bjoern Hugo Bendiksen, head of the Norwegian whalers' association.

The son, grandson and brother of a whaler, he harpooned 23 minkes this year.

"A mediocre season," he says.

While one minke whale can yield more than a tonne of meat, the processing plants on the nearby islet of Skrova pay only 30 kroner (3.8 euros, 5.5 dollars) per kilo.

Half of a season's revenue will cover the costs of the boat, while the crew, normally made up of four people, shares the rest.

"Before, whaling used to be a primary source of income. Now it's just a way for fishermen to supplement their income alongside the cod, hake and herring they catch the rest of the year," Karlsen said.

Whaling represents only 20 to 25 percent of overall income nowadays for most of the 30-odd whaling vessels that take part in the hunt in Norway each year.

In that light, whale safaris have become a more profitable business, with lower costs and less conflict. Usually.

"Once a whaler harpooned a whale right in front of us. My passengers, who were German tourists, were horrified. I almost had a heart attack," says Heiki Vester who runs the Ocean Sounds whale safari company.

Greenpeace's Gulowsen insists that "whaling is an industry of the past."

Supersize Me: Whale Meat
Resurfaces on Iceland Menus
Banned for 20 Years, It's a Hard Sale
For Young Palates; 'Moby Dick on a Stick'
Daniel Michaels, The Asian Wall Street Journal 2 Sep 08;

REYKJAVIK, Iceland -- Diners at the upscale Lobster House restaurant here can enjoy familiar appetizers such as lobster bisque or smoked eel. But the hot new starter is minke whale sashimi with wasabi crust and a shot of ginger tea on the side.

"It's traditional food made in a modern way," says chef Ulrich Jahn, who is now perfecting whale ceviche -- raw, thinly carved slices marinated in lime juice, lemon grass and garlic.

The recipes are mouthwatering to Gunnar Bergmann Jonsson, the man on a mission to introduce whale meat to a new generation of prosperous Icelanders.

After a 20-year ban on commercial whaling, Iceland in 2006 resumed limited hunting of minke whale, one of the smallest and most numerous of the main whale species. Mr. Jonsson is the sole landlubber at the country's only licensed whaling company, Hrefnuveidimenn ehf. Marketing is among his many tasks.

When Mr. Jonsson started out, he assumed that old-timers raised on whale meat would gobble up their former staple. Whale was once among the least expensive mammal meats Icelanders could buy. "We ate a lot of it back when we were all poor," says Gudlaug Thora Kristinsdottir, a cashier at Reykjavik's popular Saegreifinn seafood shack.

The restaurant sells so many $15 "Moby Dick on a Stick" whale brochettes to tourists and older Icelanders that it has to hoard extra whale meat in the freezer, she says.

But Mr. Jonsson, 30 years old, wants whale to become more than comfort food for retirees and a novelty item for visitors. To increase the market, he aims to win over young people who like to barbecue during Iceland's endless summer nights.

Red Meat of the Sea

In a bid to entice urban hipsters, Mr. Jonsson started selling marinated whale meat, vacuum-sealed and ready for cooking. Radio spots announced that the meat was back in stores. Through newspaper ads, he has tried to entice consumers by offering preparation tips, such as how to avoid overcooking. At upscale meat shops, Mr. Jonsson began distributing free recipe cards that read, "A feast for the barbecue or the pan." Recipes include whale pepper steak and whale schnitzel.

Mr. Jonsson believes he can hook people -- his age and younger -- if they only try the stuff. It looks and tastes like beef but costs about half as much. Young people should like that bargain, Mr. Jonsson reckons.

Around this city, his challenge is evident. "It's not going to happen," says 20-year-old Pall Axel Palsson. Mr. Palsson, a bellhop, has no interest in whale and other traditional Icelandic foods such as smoked sheep head, goat testicles and rotten shark.

"I don't think any kid will eat whale meat," says 11-year-old skateboarder Sindri Svensson, whose father enjoys it. "I once tried salted whale fat and almost threw up," he adds.

Although opinion polls have shown general support for whaling among Icelanders, some shun the meat because of the giant creatures' still-limited numbers. Others worry that whaling will hurt Iceland's image and thus harm its thriving tourist industry.

Eva Maria Thorarinsdottir, marketing manager of Reykjavik's Elding Whale Watching, says minke whales were much friendlier before hunting resumed, but now they avoid ships. She regards whale-hunting as akin to fox-hunting in England: a legacy kept alive only by "proud, rich traditionalists." She adds: "Our business is much more profitable than theirs."

Mr. Jonsson says Hrefnuveidimenn still isn't profitable, mainly due to scale: It has only two ships and government permission to kill around 40 minke whales each year. He's hoping local officials will eventually let the company harpoon many more -- a move that Mr. Jonsson believes could help him expand the company and allow it to pursue bigger markets, such as Japan.

Iceland and Japan are among the few countries that still hunt whales amid global opposition. Like Iceland, Japan is trying to revive a taste for whale among young people, dishing out school lunches of whale meatballs and hamburgers. Japan consumes almost 6,000 tons of minke, fin, sperm and other whale meat annually.

'Ech'

Icelanders' relationship with the red meat of the sea goes back generations. Once, hundreds of locals hunted and processed whales for their meat, blubber and bones, says former fisherman Oskar Saevarsson, who now works at the Salt Fish Museum on Iceland's south coast.

"It's part of this nation," says Mr. Saevarsson, whose father and grandfather were whalers. "In 20 years, people who remember eating whale will be gone."

As recently as the 1970s, pan-fried whale steak was a regular meal for Icelandic children. Mothers soaked the flesh overnight in milk to kill the liverlike taste that comes from exposure to air.

"Ech," says Reykjavik restaurateur Helga Bjarnidottir, grimacing at the memory. Nevertheless, she now offers $18 whale burgers with lobster mayonnaise at her Geysir Bistro.

By the 1980s, many whale species were nearing extinction from overhunting world-wide. In 1986, the International Whaling Commission, a treaty organization charged with overseeing the industry, imposed a ban on commercial whaling. Soon, whale disappeared from stores and dinner tables. Hunting resumed here two years ago when Icelandic marine authorities felt the minke-whale population was large enough to sustain it.

Mr. Jonsson concedes that luring young people back "will definitely take time." For now, he is counting on word of mouth from people like 32-year-old Haukur Margeir Hrafnsson, a Reykjavik resident with an Egyptian eye tattooed on the back of his shaved head.

"For a meat eater like me, it's a delicious substitute for beef," says Mr. Hrafnsson, as he goes for some whale sushi.

Yr Gestsdottir, a 29-year-old clothing-store clerk who hails from a fishing village in Iceland's western fiords, notes that her brother likes the stuff. "I think it's a testosterone thing," she says. "I might cook whale for my foreign friends, just to provoke them," she says. "I'd have a salad."

Where whale steak goes well with greens
In Norway there is no contradiction between eco-consciousness and eating whale meat
The Guardian 2 Sep 08;

Sitting in a restaurant in Norway, the environmental campaigner tucks into her whale steak with red wine sauce and gratinated potatoes. This time it's slightly overcooked and bitter in taste, but it won't prevent Elisabeth Saether from ordering the dish again in the future. In the Nordic country, one of only two nations in the world to conduct commercial whaling, eating a slice of whale is as common as eating cod or salmon – even for greens.

Most people here are bemused when you explain that the majority of westerners outside Norway would be horrified at the thought of eating whale meat. And none more so than in the Lofoten Islands, an archipelago about 130 miles north of the Arctic Circle and the centre of the country's whaling industry. "It's a natural resource like any other," reckons Brita Malnes, 44, behind the counter of her cornershop in the port of Henningsvaer. "People [outside Norway] get very emotional when it comes to whales, but they don't get emotional about a cod or a chicken. What's the difference?"

Round the corner, Olaug Johanssen, an energetic 81-year-old out on her daily power walk, reckons whale is good for the body. "It's a very healthy meat. I like to buy it fresh from the fishermen when they come back to shore," she said.

"French people eat snails and it's considered fine. It's the same with this," reckoned 26-year-old Erik Ellingsen as he was packing slabs of common minke whale in blue boxes at a processing plant.

Norway resumed commercial whaling in 1993, followed by Iceland in 2006 (Japan officially hunts for scientific research). Nordic fishermen only hunt one type of whale, the common minke whale, leaving orcas, like the one featured in 1993's Free Willy, well alone. Before the 1986 international moratorium, whaling was a traditional activity.

Eating whale is so normal here that the country's prime minister was filmed on a documentary cooking a slice of the red meat for his parents – the perfect way to portray himself as a regular Joe. It is safe to say Gordon Brown would not do the same stunt to curry favour with voters.

Conservation groups have not mounted high-profile campaigns here in years, as fighting whaling is not a top priority for them. "Whaling is not the biggest threat to the common minke whale," said Maren Esmark, head of conservation at WWF Norway. Other things, such as collision with ships or chemical pollution of the seas, are, she argues.

Other green groups, such as Bellona, which my dinner companion Elisabeth works for, don't even bother at all. The head of the organisation, Frederic Hauge, who was named a hero of the environment by Time magazine in 2007, comes from a well-known whaling town and reportedly has no problem with the activity. Only in Norway can you be green and eat a whale steak at the same time.

Hurricanes, Floods Show Risks of Climate Change - UN

Alister Doyle, PlanetArk 3 Sep 08;

OSLO - Atlantic hurricanes and floods in India are reminders of the risks of ever more extreme weather linked to a changing climate, the head of the United Nations Environment Programme (UNEP) said on Monday.

Achim Steiner said that more damaging weather extremes were in line with forecasts by the UN Climate Panel. He urged governments to stick to a timetable meant to end in December 2009 with a new UN pact to fight global warming.

"These natural disasters do reflect a pattern of change that is in line with projections" by experts on the Intergovernmental Panel on Climate Change (IPCC), he told Reuters in a telephone interview from Geneva.

"As you watch the hurricane season in the Atlantic, as we watch the cyclones and the flood events in India, clearly we have more reason than ever to be concerned about the unfolding of patterns that the IPCC has forecast," he said.

He said it was impossible to link individual weather events, such as Hurricane Gustav battering the US Gulf Coast on Monday, to climate change stoked by human activities led by use of fossil fuels.

But they match patterns forecast by the IPCC, which shared the 2007 Nobel Peace Prize with former US Vice President Al Gore. The IPCC is marking its 20th anniversary in Geneva this week.

Gustav slammed ashore on the US Gulf Coast just west of New Orleans on Monday, a new blow to the city devastated by Hurricane Katrina in 2005. Gustav weakened to a category 1, the lowest on a five-point scale.

In India, three million people have been displaced from their homes and at least 90 killed by floods in India's eastern state of Bihar, officials say, after the Kosi river burst a dam in Nepal. The floods are the worst in Bihar in 50 years.

In addition to the human suffering "we have an economic escalation from damage from natural disasters," Steiner said.

Insurers Munich Re said that first-half losses from natural catastrophes totalled about US$50 billion -- many linked to a rising number of extreme weather events.

The main exception was US$20 billion from China's Sichuan earthquake that killed at least 70,000 people. For all of 2007, losses totalled US$82 billion, it said in a July report.

"Growing populations and infrastructure means that we are going to face more and more events of this nature," Steiner said.

Katrina was the costliest hurricane in US history, killing some 1,500 people and causing over US$80 billion in damage.

"Natural disasters are increasingly becoming a major risk to our economies," Steiner said. "Our societies cannot afford this, our insurance industry cannot afford an escalation of risks."

Grim prospects for Australian river system as drought bites: official

Yahoo News 2 Sep 08;

Rivers in Australia's most important farming region are in critical condition thanks to the long-running drought, with no sign of an end to the 'big dry,' officials said Tuesday.

The Murray-Darling Basin Commission, which monitors the east coast region that accounts for some 40 percent of the nation's farming production, said the level of water entering the Murray River was at a record low.

Winter inflows were at their equal fifth-lowest in 117 years of records while in the two years to August, water entering the system was at a record low after persistent poor rainfall over the past seven years.

"We're continuing to establish new records that we don't particularly wish to establish," the commission's chief executive Wendy Craik told reporters.

"There's really no relief in sight. I think we can say the drought's continuing to worsen."

Australia's three longest rivers, the Murray, the Darling and the Murrumbidgee, form the Murray Darling Basin which runs from Queensland state in the north, through New South Wales, Victoria and South Australia states to the south.

The Bureau of Meteorology has said the system needs several months of torrential rain to return the rivers to health, but that such a weather pattern was not on the horizon.

"The outlook for the Murray system remains very serious," Craik said an earlier statement.

"Critical human needs can now be met through to next winter but water availability for irrigation remains very low."

Drought and irrigation have so depleted the system that freshwater lower lakes at the mouth of the Murray are turning to acid while a lack of flow along the waterways is causing headaches for farmers and environmental damage.

"Things are getting to a very critical stage with environmental deterioration and degradation right along the system and, of course, irrigators and communities are suffering as well," she said.

Craik said the fear was that after poor winter rains, spring will bring rising temperatures which further reduce water levels through evaporation.

"This drought has the fingerprints of climate change all over it," she said. "So chances are, we might be in for this for a while for the future I think."

Drought in Australia Food Bowl Worsens
Rob Taylor, PlanetArk 3 Sep 08;

CANBERRA - Drought in Australia's main food growing region of the Murray-Darling river system has worsened, with water inflows over the past two years at an all-time low, the government's top water official said on Tuesday.

The drought will hit irrigated crops such as rice, grapes and horticulture the hardest, but would have less impact on output of wheat, which depends largely on rainfall during specific periods and is on track to double after two years of shrunken crops.

The rainfall is sufficient to support hopes for a strong wheat harvest, but not enough to replenish ground water, which troubles those farmers who grow fruit rather than grain.

The record drought, which has gripped much of the country for close to a decade, was the worst in 117 years of record-keeping, with 80 percent of eucalyptus trees already dead or stressed in the region as large as France and Germany combined.

"It seems to me from what we've seen to date, there's no indication that it's going to end in the immediate future," said Wendy Craik, chief executive of the Murray-Darling Basin Commission which controls water use and flows in the rivers.

Average rainfall allowed many wheat farmers to plant crops in July, but had not reversed seven years of inflows at their lowest level since 1900, with a dry spring likely ahead, said Neil Plummer, the Acting Head of the National Climate Centre.

"What we really need to make some inroads in the situation is a big wet, and what our weather models aren't showing is a strong likelihood of a big wet over the next few months," Plummer told reporters in Canberra.

The July rains kept alive hopes of a good wheat harvest, with Australia forecast to recover from the last two drought years to boost the national 2008/09 wheat harvest to around 23.7 million tonnes, according to the official Australian Bureau of Agricultural and Resource Economics (ABARE).

Last year's crop was just 13.0 million tonnes and a farm forecaster this week said September would be a "make or break" month for crops sown this winter.

The Murray-Darling accounts for 41 percent of Australia's agriculture and provides A$21 billion (US$17.8 billion) worth of farm exports to Asia and the Middle East. Around 70 percent of irrigated agriculture comes from the basin.

The drought has already wiped more than A$20 billion from the US$1 trillion economy since 2002.

Craik said August rainfall was below average and inflows to dams and rivers during the month was only 275 gigalitres (GL), less than a fifth of the long-term average of 1,550 GL.

Dam storages, relied upon by food bowl irrigators heading into the spring and fierce Australian summer, were only 20 percent of capacity.

"The outlook for the Murray system remains very serious. Critical human needs can now be met through to next winter, but water availability for irrigation remains very low," Craik said.

Slowly warming temperatures, she said, were exacerbating the long dry, with climate scientists warning that every rise of 1.0C reducing river inflows by 15 percent in what was already the world's driest inhabited continent.

"Even with average rainfall, you won't get average inflows and the catchment dries out significantly. When it does rain in winter, we don't get the run-off that we used to," Craik said.

Plummer said the only bright spots on the climate horizon were benign neutral conditions in the Pacific and Indian oceans, which both strongly influenced Australia's weather pattens.

"That doesn't necessarily mean there will be average or above average rainfall," he said. (US$1=A$1.18) (Reporting by Rob Taylor; Editing by Clarence Fernandez)

Monsoon Misery Spreads in India; People, Rhinos Flee

Biswajyoti Das, PlanetArk 3 Sep 08;

GUWAHATI, India - Heavy rains and rising floodwaters forced hundreds of thousands of people from their homes in northeastern India and sent elephants and rhinos fleeing, as monsoon misery spread in South Asia.

In the eastern Indian state of Bihar, desperate flood victims attacked a warehouse and looted food supplies, while in neighbouring Bangladesh major rivers rose to danger levels and fresh parts of the country were submerged.

In the northeastern state of Assam, heavy rains caused water levels to rise on Tuesday, affecting more than a million people and disrupting road networks for the second consecutive day.

Animals fled to higher ground in Kaziranga National Park after the Brahmaputra burst its banks and flooded most of the park, home to more than half of the world's population of one-horned rhinoceros.

At least two rhino calves were drowned and a herd of 100 elephants were swept away by floodwaters, forest officials said.

"We are now worried the poachers will take advantage and kill rhinos and elephants as they are moving out of the protected areas to safer ground," said chief warden S. N. Buragohain.

In Bihar, the floods have already displaced about three million people and killed at least 90.

Hundreds of stick-wielding villagers ransacked a food warehouse in Madhepura district and looted food packets while police guarding the warehouse ran for cover. Government vehicles carrying food were also looted.

"We cannot stop incidents despite our best efforts," Bijendra Prasad Yadav, a state relief official, told Reuters. "These are very common during flood time."

Many villagers in impoverished Bihar have been marooned on rooftops for days with nothing to eat, while some have taken to eating plants and leaves to survive.

The Kosi river burst a dam in Nepal late last month flooding hundreds of villages across the state and destroying 100,000 ha (250,000 acres) of farmlands.

Television images showed desperate villagers driving their livestock into the Kosi river because they had no food for them.

Since the monsoon began in South Asia in June, more than 1,000 people have died in floods, with most of the casualties recorded in India's northern state of Uttar Pradesh in July.

Some experts have blamed the floods on heavier monsoon rains caused by global warming, while others say authorities have failed to take preventive measures and improve infrastructure.


NOT WELCOME HERE

Although floodwaters are rising in Assam and Bangaldesh, water levels in Bihar are receding and the government aims to evacuate all stranded villagers within the next three days.

Aid agencies have criticised the government's handling of the crisis saying they should have done more to anticipate the disaster and plan relief operations since the region is hit by monsoon flooding every year.

In Bihar, more than 560,000 people have been evacuated so far, and some 200,000 have been moved to government relief camps, officials said.

Local media reported that the first train carrying Bihar flood victims reached New Delhi on Monday, complaining of having received little or no government help.

"The fields are flooded. There's no way I can sustain my family in the next six months," Gopal Punia, a farmer from Madhepura was quoted as saying by the Indian Express newspaper.

"I will try to find work here in Delhi."

Bihar state officials have also said flood refugees would not be welcomed in Patna, the state capital.

"They should return to their respective places by the same trains," said Raj Kumar Singh, a disaster management official. (Additional reporting by Ruma Paul in Dhaka; Writing by Melanie Lee; Editing by Simon Denyer and Bill Tarrant)

Beyond Carbon: Scientists Worry About Nitrogen’s Effects

Richard Morgan, The New York Times 1 Sep 08;

TOOLIK FIELD STATION, Alaska — As Anne Giblin was lugging four-foot tubes of Arctic lakebed mud from her inflatable raft to her nearby lab this summer, she said, “Mud is a great storyteller.”

Dr. Giblin, a senior scientist at the Marine Biological Laboratory in Woods Hole, Mass., is part of the Long Term Ecological Research network at an Arctic science outpost here operated by the University of Alaska at Fairbanks.

Public discussion of complicated climate change is largely reduced to carbon: carbon emissions, carbon footprints, carbon trading. But other chemicals have large roles in the planet’s health, and the one Dr. Giblin is looking for in Arctic mud, one that a growing number of other researchers are also concentrating on, is nitrogen.

In addition to having a role in climate change, nitrogen has a huge, probably more important biological impact through its presence in fertilizer. Peter Vitousek, a Stanford ecologist whose 1994 essay put nitrogen on the environmental map, co-authored a study this summer in the journal Nature that put greater attention on the nitrogen cycle and warned against ignoring it in favor of carbon benefits.

For example, Dr. Vitousek said in an interview, “There’s a great danger in doing something like, oh, overfertilizing a cornfield to boost biofuel consumption, where the carbon benefits are far outweighed by the nitrogen damage.”

Soon after Dr. Vitousek’s report, the journal Geophysical Research Letters branded as a “missing greenhouse gas” nitrogen trifluoride, which is used in production of semiconductors and in liquid-crystal displays found in many electronics. Nitrogen trifluoride, which is not one of the six gases covered by the Kyoto Protocol, the celebrated international global warming accord, is about 17,000 times more potent than carbon dioxide. Its estimated worldwide release into the atmosphere this year is equivalent to the total global-warming emissions from Austria.

“The nitrogen dilemma,” Dr. Vitousek added, “is not just thinking that carbon is all that matters. But also thinking that global warming is the only environmental issue. The weakening of biodiversity, the pollution of rivers, these are local issues that need local attention. Smog. Acid rain. Coasts. Forests. It’s all nitrogen.”

Dr. Vitousek’s summer report followed a similar account in May in the journal Science by James N. Galloway, an environmental sciences professor at the University of Virginia and a former chairman of the International Nitrogen Initiative, a group of scientists pushing for smarter use of nitrogen.

Dr. Galloway is developing a universal calculator for individual nitrogen footprints. “It’s Goldilocks’s problem,” he said in an interview. “Reactive nitrogen isn’t a waste product. We need it desperately. Just not too much and not too little. It’s just more complicated than carbon.” He continued, “But we’re not going to get anywhere telling people this is simple or easy.”

Dr. Giblin of Woods Hole spent the summer at the field station here, midway between the Arctic Circle and the Arctic Ocean, researching the nitrogen content of lakebed sediment — not the inert nitrogen that makes up 80 percent of air, the reactive nitrogen that Dr. Galloway referred to. In forms like nitric acid, nitrous oxide, ammonia and nitrate it plays a variety of roles.

Nitrogen is part of all living matter. When plants and animals die, their nitrogen is passed into soil and the nitrogen in the soil, in turn, nourishes plants on land and seeps into bodies of water. Dr. Giblin is pursuing her research because as the Arctic warms, the tundra’s permafrost will thaw, and the soil will release carbon and nitrogen into the atmosphere.

When an ecosystem has too much nitrogen, the first response is that life blossoms. More fish, more plants, more everything. But this quickly becomes a kind of nitrogen cancer. Waters cloud and are overrun with foul-smelling algae blooms that can cause toxic “dead zones.” Scientists call this process eutrophication, but the laymen’s translation is that the water gets mucked up beyond all recognition. A recent such plague bedeviled China when its Yellow Sea was smothered in algae at Qingdao, the planned site of Olympic sailing events this summer. More than mere inconvenience, such problems routinely threaten many coastal areas and riverside communities.

Nancy Rabalais, executive director of the Louisiana Universities Marine Consortium, is known as Queen of the Dead Zone. She cruises around the Gulf of Mexico every summer in the research vessel Pelican to look for damage from nitrogen-rich river flows into the gulf. This year, she expects a dead zone that will beat the Massachusetts-size 8,500-square-mile bloom of 2002.

One of the problems, Dr. Rabalais said, is that the Mississippi River involves so many communities that it requires stronger federal guidance, which she said was not a part of the Bush administration’s policies. She is part of a national research committee financed by the Environmental Protection Agency and run by the National Academies of Science, but, she said, “it’s so much talk and not enough action.”

She continued: “Because you’re not just going up against the agribusiness lobby, but also the livelihood of farmers. It’s not exactly popular in the Midwest.”

Fertilizer use is largely inefficient. With beef, only about 6 percent of nitrogen used in raising cows ends up in their meat; the rest leeches out into air or water supplies. With pork, it is 12 percent; chicken, 25 percent. Milk, eggs and grain have the highest efficiency, about 35 percent, or half of what, in the metric of report cards, is a C-minus.

“Look,” she said, “you just can’t have all these states and all these communities knowingly overfertilizing their land because they want a bumper crop every year. That’s just all kinds of bad. But Des Moines, for example, is willing to filter their drinking water to an extra degree just to be able to flood their water supply with more-than-normal levels of fertilizer.”

Reactive nitrogen competes with greenhouse gases that have greater public awareness. “But it’s like looking at malaria and AIDS in Africa,” Dr. Rabalais said. “They’re both problems. And they both need vigilant attention.”

Environmentalists face the puzzle of how to deal with multiple problems at once. And some worry that after the hard-fought campaign spotlighting carbon, turning to focus on nitrogen could upset that momentum.

The tension can plague even the most informed and articulate campaigners. “One of the many complexities that complicate the task I’ve undertaken is complexity,” said Al Gore, the former vice president who won a Noble Peace Prize for his environmental work. Mr. Gore added, “Look, I can start a talk by saying, ‘There are 14 global warming pollutants, and we have a different solution for addressing each of them.’ And it’s true. But you start to lose people.”

Seawater greenhouses to bring life to the desert

The planned project would use solar power to evaporate salt water, generating cool air and pure water thereby allowing food to be grown

Alok Jha, guardian.co.uks 2 Sep 08;

Vast greenhouses that use seawater to grow crops could be combined with solar power plants to provide food, fresh water and clean energy in deserts, under an ambitious proposal from a team of architects and engineers.

The Sahara Forest project would marry huge greenhouses with concentrated solar power (CSP), which uses mirrors to focus the sun's rays and generate heat and electricity. The installations would turn deserts into lush patches of vegetation, according to its designers, and without the need to dig wells for fresh water, which has depleted acquifers in many parts of the world.
The team includes one of the lead architects behind Cornwall's Eden project and demonstration plants are already running in Tenerife, Oman and the United Arab Emirates.

Plants cannot grow in deserts because of the extreme temperatures and lack of nutrients and water. Charlie Paton, one of the Sahara Forest team and the inventor of the seawater greenhouse concept, said his technology was a proven way to transform arid environments.

"Plants need light for growth but they don't like heat beyond a certain point," said Paton. Above a particular temperature, the amount of water lost through the holes in its leaves, called stomata, gets so large that a plant will shut down photosynthesis and cannot grow.

The greenhouses work by using the solar farm to power seawater evaporators and then pump the damp, cool air through the greenhouse. This reduces the temperature by about 15C compared to that outside. At the other end of the greenhouse from the evaporators, the water vapour is condensed. Some of this fresh water is used to water the crops, while the rest can be used for the essential task of cleaning the solar mirrors.

"So we've got conditions in the greenhouse of high humidity and lower temperature," said Paton. "The crops sitting in this slightly steamy, humid condition can grow fantastically well."

The designers said that virtually any vegetables could be grown in the greenhouses, depending on the conditions at which it is maintained. The demonstration plants already produce lettuces, peppers, cucumbers and tomatoes. The nutrients to grow the plants could come from local seaweed or even be extracted from the seawater itself.

Michael Pawlyn of Exploration Architecture, who worked on the Eden Project for seven years and is now part of the Sahara Forest team, said the seawater greenhouse and CSP provided substantial synergies for each other. "Both technologies work extremely well in hot, dry desert locations – CSP produces a lot of waste heat and we'd be able to use that to evaporate more seawater from the greenhouse," he said. "And CSP needs a supply of clean, demineralised water in order for the [electricity generating] turbines to function and to keep the mirrors at peak output. It just so happens the seawater greenhouse produces large quantities of this."

Paton said that the greenhouse produces more than five times the fresh water needed to water the plants inside so, in addition to producing water to clean the CSP mirrors, some of it can be released into the local environment. This can create a local microclimate just outside the greenhouses for hardier plants such as jatropha, an energy crop that can be turned into biofuel. The ability to create similar microclimates has already been proven in the demonstration greenhouses Paton has built.

The cost of the Sahara Forest project could be relatively low since both CSP and seawater greenhouses are proven technologies – the designers estimate that building 20 hectares of greenhouses combined with a 10MW CSP scheme would cost around €80m (£65m). Paton said groups in countries across the Middle East, including UAE, Oman, Bahrain, Qatar and Kuwait, have expressed interest in the possibility of funding demonstration projects.

He added that using seawater greenhouses could reverse the environmental damage done by the greenhouses already built in places such as Almeria in southern Spain. More than 40,000 hectares of greenhouses have been built in this desert region during the past 20 years to grow salad vegetables. "They take water out of the ground something like five times faster than it comes in, so the water table drops and becomes more saline. The whole of Spain is being sucked dry. If one were to convert them all to the seawater greenhouse concept, it would turn an unsustainable solution into a more sustainable one."

"In places like Oman, they've effectively sterilised large areas of land by using groundwater that's become increasingly saline," said Pawlyn. "The beauty of the Sahara Forest scheme is that you can reverse that process and turn barren land into biologically-productive land."

Neil Crumpton, an energy specialist at Friends of the Earth, said the potential of desert technologies was huge. "Concentrated solar power mirror arrays covering just one per cent of the Earth's deserts could supply a fifth of all current global energy consumption. And one million tonnes of sea water could be evaporated every day from just 20,000 hectares of greenhouses."

He added: "Governments around the world should invest serious money in these solar energy and water technologies and not be distracted by lobbyists promoting dangerous nuclear power or nuclear-powered desalination schemes."

Harnessing the desert sun's rays is already at the heart of an ambitious European scheme to build a €45bn (£35.7bn) supergrid that could allow countries across the continent to share renewable electricity from solar power in north Africa, wind energy in the UK and Denmark, and geothermal energy from Iceland and Italy. The north Africa solar plan has already gained political support in Europe from Gordon Brown and Nicolas Sarkozy. Though expensive, it is in line with International Energy Agency estimates that the world needs to invest more than $45tn (£22.5tn) in new energy systems over the next 30 years.

Solar panels 'take 100 years to pay back installation costs'

Martin Hickman, The Independent 3 Sep 08;

Solar panels are one of the least cost-effective ways of combating climate change and will take 100 years to pay back their installation costs, the Royal Institution of Chartered Surveyors (Rics) warned yesterday.

In a new guide on energy efficiency, Rics said that roof panels for heating water and generating power are unlikely to save enough from bills to make them financially viable in a householder's lifetime. In the case of solar panels to heat water for baths and showers, the institution estimates the payback time from money saved from electricity and gas bills will take more than 100 years – and up to 166 years in the worst case.

Photovoltaic (PV) panels for power – and domestic, mast-mounted wind turbines – will take between 50 and 100 years to pay back.

Given that the devices have a maximum lifetime of 30 years, they are never likely to recoup the £3,000 to £20,000 cost of their installation, according to Rics' building cost information service. Instead, it suggested people wanting to cut fuel bills should insulate lofts and cavity walls, install efficient light bulbs and seal windows.

Joe Martin, author of Rics' Greener Homes Prices Guide, said there was an argument for installing solar panels but it was not an economic one. "We wanted to bring some reality to this because there are a lot of missionaries out there. The whole push for household renewable power is that you can do these things and make back money but that's not true on existing property," he said.

The solar power industry accused Rics of failing to take account of the rising cost of energy and other financial benefits of renewable power in its figures. Jeremy Leggett, of Solar Century, said: "They are grossly irresponsible."

Rics assessed the cost, annual savings, disruption and payback time of various energy-saving methods and gave each an overall rating of one to five stars.

Solar panels for heating and power and wind turbines generating between 3kW and 5kW merited two stars. Smaller 1.5kW turbines of the type installed on roofs paid back in 25 years, received a three-star rating.

By contrast, cavity wall insulation had a five-star rating: spending £440 would save £145 a year in fuel bills, paying back in three years, while an investment of £325 in extra loft insulation would save £60 annually, paying back in five years.

The figures were compiled before energy companies put up bills by up to 30 per cent last month and ignore state subsidies.

Last year, the Department for Trade and Industry slashed grants for the installation of household renewable power by 83 per cent, infuriating the fledgling micro-generation industry which complained the move rendered solar panels unaffordable to all but the wealthy.

Jeremy Leggett, executive chairman of Solar Century, complained that Rics' figures failed to assume any rise in energy prices, when a conservative estimate of 10 per cent a year would transform the calculations.

In addition, Rics had failed to take account of a number of other benefits – renewable obligations certificates worth £160 a year to householders from next year; reductions in energy consumption of up to 40 per cent for schemes with a meter; the rising payments from energy companies for spare electricity put back into the national grid; and the increased value of an energy-efficient home.

He estimated the current payback of power-generating PV panels was 13 years.

Rics countered by saying it had not taken account of maintenance costs and that it deliberately chose not to include "ifs" in its figures. "I doubt however you do the sums, they [solar panels] make sense," a spokesman said.
