Birds of prey rid Warsaw metro of urban scourge

Maja Czarnecka Yahoo News 28 Sep 09;

WARSAW (AFP) – Determined to keep its metro free of pigeon droppings, city transport authorities in Poland's capital have tapped the "killer" instinct of birds of prey to deal with this universal urban scourge.

"Just the presence of a bird of prey inside or at the entrance of a station is enough to act as a deterrent," says Piotr Zadworny, a bird breeder whom Warsaw subway authorities hired to solve their pigeon woes.

His two Harris hawks Draka and Mietek, a variety native to Central America, do the trick.

"Hawks are the natural prey of pigeons. They know very well that the appearance of a hawk means their death," Zadworny says.

"Just a few days of the hawks' presence is enough to make the pigeons vanish," he adds.

Before he began making his rounds with Draka and Mietek, the Sluzew metro station in southern Warsaw was plagued by hundreds of pigeons. Within just days, the number dwindled to a handful.

"I couldn't stand it anymore! The pigeons weren't afraid of anything, they would just fly into my kiosk and start eating the pastries," the owner of a small shop inside the metro station told AFP.

With Draka, a female hawk from Mexico perched on his arm clad in a thick leather glove, Piotr chases away the pesky birds.

Most make their nests between cables running along the ceiling and walls. Pigeon droppings mar walls, cover the metro's granite floors and plop onto passengers' heads.

The chirps of baby pigeons coming from a space between two boards draw Draka's attention. As soon as an adult pigeon appears, she takes flight in pursuit. Piotr lets her briefly chase the bird, then calls her back.

They may scare pigeons, but are they allowed to kill them?

"Absolutely not! First, it would be contrary to a law which protects even pigeons. Secondly, it would be too dangerous, my birds could die -- urban pigeons carry many diseases," says Piotr.

"They're worse than rats -- it's a veritable epidemiological bomb," he adds.

His birds eat only chick meat that is frozen immediately upon slaughter to kill any harmful microbes. "Yes, it's brutal," he admits.

But with birds of prey worth between 10,000 to 30,000 euros (14,800 - 44,400 dollars), the risk of disease must be kept to a minimum.

Draka works about five hours a day, before she shows signs of boredom. Her mate Mietek takes over then, Piotr says.

The cost of their services is a confidential matter. "It won't take long to recoup our investment," says Warsaw metro spokesman Krzysztof Malawko.

"The huge costs of cleaning the stations, the maintenance products and above all renovation work on the walls and ceilings will drop dramatically," he adds.

"We battled against the pigeons for years, without any success. We tried everything."

At wits end, metro authorities decided to seek advice from ornithologists.

They now plan to remove all the nests and cover the nooks and crannies with wire mesh to prevent pigeons from returning.

Opened in 1995, the Warsaw metro beat Singapore's to win a prize a few months ago as the world's most environmentally friendly system in a London-based international contest.

According to Malawko, no other metro system in the world uses birds of prey against pigeon, although airports are known to do so to clear birds off runways.

The services of Draka, Mietek and Zadworny, who also works part-time as an IT specialist, are most often sought by farmers who hire him to clear birds from crops. Municipalities also engage him to control crow populations in public parks.

His greatest passion is training the birds -- and he's taught his hawks a few tricks. Mietek, he says, has even learned how to undress a woman. Using only his yellow beak, the hawk can deftly undo the clasp on the bra of a woman who is lying on her stomach, Zadworny boasts.

Pacific islands seek "outdated" fish pact change

Giff Johnson Yahoo News 27 Sep 09;

MAJURO (AFP) – The United States and Pacific nations are heading for a showdown over the management of the four-billion dollar tuna industry with the island states saying their current treaty is outdated.

However, the United States says the 25-year-old agreement with the Pacific Forum Fisheries Agency (FFA), which is to be reviewed next month, is considered valuable by "the vast majority" of Pacific states.

Criticism of the United States is being driven by the upsurge from 12 to 40 US-flagged fishing vessels in the region at a time when the Pacific is changing from the US-treaty formula of licensing boats.

It is being replaced by a "vessel day scheme" where licences are based on the number of days rather than number of boats as part of a move to reduce the tuna catch to 2004 levels.

Washington originally negotiated the fishing treaty with the FFA in 1987 to end a diplomatic crisis in the Pacific when the United States' purse seine fishing fleet was regarded as fishing illegally and flouting the rules.

The treaty gives the US access to the economic zones of the 16 FFA nations for a fee currently set at 21 million dollars a year.

However, the FFA nations say that in the past year tuna conservation and management measures have changed in the region.

There is increasing concern about overfishing of bigeye and yellowfin tuna, and also the island nations are demanding a bigger share of the four billion dollar Pacific tuna industry.

They say they will be pushing for this to be taken into consideration at the US-Pacific fisheries treaty review in the Solomon Islands next month.

"The US treaty is outdated," said Glen Joseph, director of the Marshall Islands Marine Resources Authority.

"It needs updating in light of the new Tuna Commission rules and current initiatives of the Parties to the Nauru Agreement (PNA)."

The PNA countries -- Papua New Guinea, Solomon Islands, Nauru, Federated States of Micronesia, Palau, Marshall Islands, Kiribati and Tuvalu -- control the waters where most of the annual haul of tuna is caught.

US to decide on listing ice seals as threatened

Dan Joling, Associated Press Yahoo News 29 Sep 09;

ANCHORAGE, Alaska – A federal agency must decide within three weeks whether spotted seals, which depend on sea ice off Alaska's coast, should be listed as a threatened or endangered species.

In addition, the National Oceanic and Atmospheric Administration agreed to decide by Nov. 1, 2010, whether two other ice-dependent seals, ringed seals and bearded seals, should be listed.

A federal judge Friday approved the settlement between NOAA and the Center for Biological Diversity, which had sued to force a decision.

Center spokeswoman Rebecca Noblin said Monday the group was happy the agency had set the dates, since the summer sea ice minimum this year was the third-lowest since satellite measurements began in 1979.

"The quicker we can get protection for these seals, the better," she said.

NOAA officials in December denied listing ribbon seals as threatened or endangered. They said climate models project annual ice for the seals will continue to form each winter during the critical birthing and molting period. The Center for Biological Diversity has sued to reverse the decision.

John Kurland, acting deputy regional administrator of NOAA, said the agency has been studying spotted, ringed and bearded seals. Spotted seals had a similar distribution and an information overlap with ribbon seals, he said.

Information on the other two types of seals is more complicated, and the extra time will let the agency incorporate information compiled by the state of Alaska, Kurland said.

Ringed, bearded and spotted seals use sea ice in different ways for giving birth, rearing pups and resting. All three live in the Bering, Chukchi or Beaufort seas off Alaska's western and northern coasts.

The Center for Biological Diversity petitioned to list the seals in May 2008, the same month former Interior Secretary Dirk Kempthorne declared polar bears threatened because of sea ice loss.

The agency missed the one-year deadline for a decision, and the environmental group sued.

Spotted seals use the edge of sea ice far from predators to give birth and nurse pups. Loss of sea ice and early ice breakup threaten their ability to rear young, according to the listing petition.

Ringed seals are the primary prey of polar bears. They are the only seals that can live in completely ice-covered waters, using stout claws to dig and maintain breathing holes. They excavate snow caves on sea ice to provide insulated shelters for themselves and their pups.

Early breakup of sea ice threatens lairs during critical rearing periods when pups are too young to survive in water, according to the group. Warming also can expose lairs and make pups vulnerable to polar bears and Arctic foxes.

Bearded seals give birth and rear pups on drifting pack ice over shallow waters where prey is abundant. The retreat of sea ice away from shallow shelves decreases food availability, the environmental group said.

Federal agencies are required to consider how their regulatory decisions affect listed and threatened species.

Dragonflies go thirsty in the Mediterranean

IUCN 29 Sep 09;

One fifth of Mediterranean dragonflies and damselflies are threatened with extinction at the regional level as a result of increasing freshwater scarcity, according to the IUCN Red List of Threatened Species™.

Climate change and habitat degradation, due to the way land is managed, are also affecting the insects, says the report.

The assessment of 163 Mediterranean dragonflies and damselflies shows five are Critically Endangered, 13 are Endangered, another 13 are Vulnerable, 27 are Near Threatened, 96 are Least Concern and six are Data Deficient, meaning there is not enough information to classify them, but they might also be threatened.

“It is likely things will only get worse for these unique species as climate change and increased water demand take their toll,” says Jean Pierre Boudot, member of the IUCN Dragonfly Specialist Group and co-author of the report. “Lower levels of precipitation and drought will lead to degradation of the habitats where the majority of dragonflies and damselflies live.”

Four species are already listed as Extinct in the Mediterranean, including the Little Whisp (Agriocnemis exilis), the Common Pond Damsel (Ceriagrion glabrum), the Phantom Flutterer (Rhyothemis semihyalina) and the Darting Cruiser (Phyllomacromia africana).

Dragonflies are generally known for being good indicators of water quality. Major threats for 67 percent of these Mediterranean species are habitat degradation and pollution. The Spotted Darter (Sympetrum depressiusculum), which used to be common in the Mediterranean, is now listed as Vulnerable and is declining due to the intensification of agricultural practices in rice fields.

Fourteen percent of these insect species can be found only in Mediterranean freshwater ecosystems, some of the richest and most threatened habitats, among which nine have been assessed as Endangered or Vulnerable. According to the report, the highest numbers of endemic dragonflies are present in the South and West of the Mediterranean, with the Maghreb and the Levant areas being regional hotspots of endemism.

The majority of the threatened species are concentrated in the Levant, southern Turkey and Balkans, northeast Algeria and northern Tunisia. The Glittering Demoiselle (Calopteryx exul), for example, is listed as Endangered and is in decline. It inhabits the aquatic habitats of the Maghreb, whose ecosystems are under pressure due to water-harnessing for human use, water pollution, irrigation and drought.

Long-term coordinated actions are needed at regional, national and international level, and the results of this report highlight the responsibility that Mediterranean countries have to protect the global populations. Though some species are already receiving some conservation attention thanks to international laws, such as the Ornate Bluet (Coenagrion ornatum) which is included in the European Habitat Directive, others are not protected at all, despite their high risk of extinction.

“The selection and protection of key sites are essential to ensure the survival of these species,” says IUCN’s Annabelle Cuttelod, co-author of the report. “Their ecological requirements need to be taken into account in the planning and management of water use, especially for agriculture purposes or infrastructure development. IUCN Red List data can inform both processes.”

Better world: Global green heroes

New Scientist 28 Sep 09;

It is no secret that the environment is facing some major challenges. Yet despite all the gloom there are some corners of the world where things are changing for the better. Here are a few examples to prove that when communities, city officials and governments put their minds to it they can move environmental mountains. Now all we need is more of the same, and fast...

Ecotown after the storm
Greensburg, Kansas, US

The small town of Greensburg was flattened by a 3-kilometre-wide tornado in May 2007, leaving 90 per cent of the 1500-strong population homeless. Days after the storm passed, the community voted to rebuild Greensburg as energy-efficiently as possible. More than half of the rebuilt homes contain state-of-the-art insulation and built-in means of generating renewable energy. There are plans to install ten 1.25-megawatt wind turbines to supply the rest.
Fisheries success

North Atlantic

In 2000, north Atlantic albacore tuna stocks were only half of what could be considered sustainable. Then the International Commission for the Conservation of Atlantic Tunas took the advice of its scientific advisers and radically cut quotas in the region. Stocks have since recovered to within 20 per cent of sustainable levels.
Changing places

Totnes, Devon, UK

Totnes is a leading example of the transition movement, a global organisation which now boasts some 600 communities keen to equip themselves with the tools and know-how to survive when oil supplies run dry and climate change bites. Among other things, Totnes has its own currency, its inhabitants are growing and promoting local produce, and they have set up their own sustainable-building company.
Going carbon-neutral

Costa Rica

Costa Rica already generates around two-thirds of its energy from renewable sources, and over a third of its land has been designated as national park. In 2008 the nation took things a step further, making a pledge to go carbon-neutral by 2021. Around 12 million trees have been planted in the past two years, funded in part by a tax on gasoline. The next step is to offset the carbon dioxide produced by the farming and packaging of its main exports, bananas and pineapples.
The good life

Todmorden, West Yorkshire, UK

The community in this small town has embarked on a mission to transform every spare bit of green space into a communal larder. Its schools and public parks are bursting with vegetable plots, there's a 200-tree orchard in the town centre and crops are even sprouting in the town's cemetery. Residents can harvest this public produce for free. Todmorden hopes to be fully self-sufficient in fruit, vegetables and eggs by 2018.
No cars, thanks

Vauban, near Freiburg, Germany

Residents of Vauban, a new suburb of Freiburg in Germany built on the site of an old army barracks, have done what many suburbanites regard as impossible: given up their cars in favour of travel by bicycle and tram. The 30 per cent of residents that chose to keep their cars have to park them on the outskirts of the suburb. The rest use public transport or hire cars when they need them from a car club.
Energy sharing

Samsø, Denmark

The small Danish island of Samsø has become the model for community energy generation. Almost every household owns shares in the local wind farm, and the 4300 residents produce their own heat by burning locally grown straw in community heating plants. They also run their vehicles on rapeseed oil. The island's 21 wind turbines generate more electricity than the residents need, allowing them to sell the excess to the mainland.
Recycling improvers

Czech Republic

The Czech Republic could soon be the world recycling champion, overtaking established leaders such as Germany and Belgium, according to the latest figures from the European Union. The country has more than doubled how much packaging it recycles, from 29 per cent in 2002 to 63 per cent in 2006. It is now setting its sights on improving recycling rates for electronic and organic waste.
Rainwater harvesting

Rural India

Water tables across India are falling fast, threatening crops. Some rural areas have bucked the trend by re-embracing the art of rainwater harvesting. Residents of the village of Limbadia in western Gujarat have built small dams on local rivers, allowing monsoon run-off to seep into underground reservoirs. The village's wells now leak at the surface and long-dried streams have reappeared.
No wood required

China / sub-Saharan Africa

China is fast becoming a leader in designing affordable, environmentally friendly technologies for the rural poor of the developing world. Solar ovens, for instance, concentrate the sun's rays to create heat and cook food, reducing wood and charcoal use. Chinese companies have begun exporting solar technology to sub-Saharan Africa, while NGOs based in the US and South Africa are providing cookers in Kenya, Zimbabwe and Zambia.
Sun, not coal

Rizhao, northern China

In Rizhao, 99 per cent of all households use solar power to heat their waterMovie Camera - the result of a decade of government subsidies for solar research and development, financial incentives, education programmes and building regulations. The Worldwatch Institute, a research organisation based in Washington DC, calculates that it saves families 3 to 6 per cent of their income compared with electrical heating. Air quality in the region has also improved.
Bottled-water ban

Bundanoon, New South Wales, Australia

In July, the residents of Bundanoon voted to ban the sale of bottled water. The vote came after a company announced plans to tap the local aquifer, bottle the water in Sydney and sell it back to the town. Locals can now pay to refill their bottles with chilled, filtered tap water in stores, or fill up for free at public water fountains - saving 200 millilitres of oil for every litre of bottled water not produced.

China's green sweep will blow the world

Thomas L. Friedman, Straits Times 29 Sep 09;

MOST people would assume that 20 years from now, when historians look back at 2008-09, they will conclude that the most important thing to happen in this period was the Great Recession. I'd hold off on that. If we can continue stumbling out of this economic crisis, I believe future historians may well conclude that the most important thing to happen in the last 18 months was that Red China decided to become Green China.

Yes, China's leaders have decided to go green - out of necessity because too many of their people can't breathe, can't swim, can't fish, can't farm and can't drink thanks to pollution from its coal- and oil-based manufacturing growth engine. And, therefore, unless it powers its development with cleaner energy systems and more knowledge-intensive businesses without smokestacks, China will die of its own development.

What do we know about necessity? It is the mother of invention. And when China decides it has to go green out of necessity, watch out. You will not just be buying your toys from China. You will buy your next electric car, solar panels, batteries and energy-efficiency software from China.

I believe this Chinese decision to go green is the 21st-century equivalent of the Soviet Union's 1957 launch of Sputnik - the world's first Earth-orbiting satellite. That launch stunned Americans, convinced then-President Dwight Eisenhower that the US was falling behind in missile technology and spurred America to make massive investments in science, education, infrastructure and networking - one eventual by-product of which was the Internet.

Well folks, Sputnik just went up again: China's going clean-tech. The view of China in the United States Congress - that China is going to try to leapfrog the US by out-polluting it - is out of date. It's going to try to out-green the US. Right now, China is focused on low-cost manufacturing of solar, wind and batteries and building the world's biggest market for these products. It still badly lags US innovation. But research will follow the market. America's premier solar equipment maker, Applied Materials, is about to open the world's largest privately funded solar research facility - in Xian, China.

'If they invest in 21st-century technologies and we invest in 20th-century technologies, they'll win,' says Mr David Sandalow, the Assistant Secretary of Energy for Policy.

'If we both invest in 21st-century technologies, challenging each other, we all win.'

Unfortunately, Americans are still not racing. It's like Sputnik went up and Americans think it's just a shooting star. Instead of a strategic response, too many US politicians are still trapped in their own dumb-as-we-wanna-be bubble, where the US is always No. 1, and where the US Chamber of Commerce, having sold its soul to the old coal and oil industries, uses its influence to prevent Congress from passing legislation to really spur renewables.

China's leaders, mostly engineers, wasted little time debating global warming. They know the Tibetan glaciers that feed their major rivers are melting. But they also know that even if climate change were a hoax, the demand for clean, renewable power is going to soar as we add an estimated 2.5 billion people to the planet by 2050, many of whom will want to live high-energy lifestyles. In that world, ET - or energy technology - will be as big as IT, and China intends to be a big ET player.

'For the last three years, the US has led the world in new wind generation,' said the ecologist Lester Brown, author of Plan B 4.0.

'By the end of this year, China will bypass us on new wind generation so fast we won't even see it go by.'

I recently met Mr Shi Zhengrong, the founder of Suntech, already the world's largest manufacturer of solar panels. Mr Shi recalled how, shortly after he started his company in Wuxi, the nearby Lake Tai, China's third-largest freshwater lake, choked to death from pollution.

'After this disaster,' explained Mr Shi, 'the party secretary of Wuxi city came to me and said, 'I want to support you to grow this solar business into a US$15 billion (S$21 billion) industry, so then we can shut down as many polluting and energy consuming companies in the region as soon as possible.' He is one of a group of young Chinese leaders, very innovative and very revolutionary, on this issue. Something has changed. China realised it has no capacity to absorb all this waste. We have to grow without pollution.'

Of course, China will continue to grow with cheap, dirty coal, to arrest over-eager environmentalists and to strip African forests for wood and minerals. Have no doubt about that. But have no doubt either that, without declaring it, China is embarking on a new, parallel path of clean power deployment and innovation. It is the Sputnik of our day. Americans ignore it at their peril.

Smuggling Europe's Waste to Poorer Countries

Elisabeth Rosenthal, The New York Times 26 Sep 09;

ROTTERDAM, the Netherlands — When two inspectors swung open the doors of a battered red shipping container here, they confronted a graveyard of Europe’s electronic waste — old wires, electricity meters, circuit boards — mixed with remnants of cardboard and plastic.

“This is supposed to be going to China, but it isn’t going anywhere,” said Arno Vink, an inspector from the Dutch environment ministry who impounded the container because of Europe’s strict new laws that place restrictions on all types of waste exports, from dirty pipes to broken computers to household trash.

Exporting waste illegally to poor countries has become a vast and growing international business, as companies try to minimize the costs of new environmental laws, like those here, that tax waste or require that it be recycled or otherwise disposed of in an environmentally responsible way.

Rotterdam, the busiest port in Europe, has unwittingly become Europe’s main external garbage chute, a gateway for trash bound for places like China, Indonesia, India and Africa. There, electronic waste and construction debris containing toxic chemicals are often dismantled by children at great cost to their health. Other garbage that is supposed to be recycled according to European law may be simply burned or left to rot, polluting air and water and releasing the heat-trapping gases linked to global warming.

While much of the international waste trade is legal, sent to qualified overseas recyclers, a big chunk is not. For a price, underground traders make Europe’s waste disappear overseas.

After Europe first mandated recycling electronics like televisions and computers, two to three million tons of electronic waste was turned in last year, far less than the seven million tons anticipated. Much of the rest was probably exported illegally, according to the European Environment Agency.

Paper, plastic and metal trash exported from Europe rose tenfold from 1995 to 2007, the agency says, with 20 million containers of waste now shipped each year either legally or illegally. Half of that passes through this huge port, where trucks and ships exchange goods around the clock.

In the United States, more states are passing laws that require the recycling of goods, especially electronics. But because the United States places fewer restrictions on trash exports and monitors them far less than Europe, that increasing volume is flowing relatively freely overseas, mostly legally, experts say. Up to 100 containers of waste from the United States and Canada arrive each day, according to environmental groups and local authorities in Hong Kong.

“Now we are collecting far more, but they can’t prevent it from going offshore. People talk about ‘leakage,’ but it’s really a hemorrhage,” said Jim Puckett, director of the Basel Action Network, a Seattle-based environmental nonprofit that tracks waste exported from the United States.

The temptation to export waste is great because recycling properly at home is expensive: Because of Europe’s new environmental laws, it is four times as expensive to incinerate trash in the Netherlands as to put it — illegally — on a boat to China. And the vast container ships that arrive in Europe and North America from Asia filled with cheap garments and electrical goods now have a profitable return cargo: garbage like steel cables, circuit boards and leftovers from last night’s pasta meal.

“The traffic in waste exports has become enormous,” said Christian Fischer, chief consultant on waste to the European Environment Agency, which released its first study on the topic this year, “but we need much better information about it.”

The Dutch have taken a lonely lead in inspecting waste exports and curbing the traffic, providing a rare window into the trade. They estimate that 16 percent of the exports are illegal. But in most ports where customs inspectors typically check imports far more thoroughly than exports, much probably passes through unnoticed.

In July, a shipment of 1,400 metric tons of British household garbage that was illegally sent to South America — labeled as clean plastic for recycling — was apprehended only after it landed in Brazil.

Rotterdam uses X-rays and computer analysis of shipping documents to pick out suspicious containers. But other countries need to do more, said Albert Klingenberg of the Dutch environment ministry, adding: “When they can’t get it out in Rotterdam, they go to Antwerp or Hamburg.”

The European Union’s laws governing waste disposal require more recycling of paper and plastic each year, and generally prohibit dumping in landfills. Incineration is now heavily taxed in most European countries.

The regulations also prohibit exporting waste to poorer parts of the world unless the receiving country accepts that kind of waste and it is going to a certified recycler. The guidelines fully ban the export of certain hazardous materials and so-called “problematic” waste, defined as waste that is not amenable to recycling and so would be harmful to the environment at its destination, for example, waste that is soggy or mixed household garbage.

The European laws generally follow the guidelines of the 1992 Basel Convention, the treaty that regulates dangerous exports of waste, and a proposed 1998 amendment.

Nanotech 'an environment risk'

CRC CARE, Science Alert 29 Sep 09;

The widespread and growing use of nanoparticles is causing a new form of uncontrollable and unregulated pollution that has the potential to harm the environment, a leading scientist warned the CleanUp 09 conference in Adelaide on 28 September.

Nanoparticles’ extremely small size – only billionths of a metre – makes them ideal for use in a growing range of industries and products, but it also allows them to escape through filters and into our rivers, oceans and even to penetrate our bodies.

Dr Tomas Vanek from the Laboratory of Plant Biotechnologies in the Czech Republic will talk about how important it is to understand the damage that this ‘nanopollution’ can cause and the urgent need to control it.

Body creams and toothpastes increasingly contain nanoparticles, as do a range of commercial products and a variety of materials. Nanoparticles are also used in industrial processes, and this range of applications allows them to be exposed to the environment through many different pathways, according to Dr Vanek.

“Nanoparticles often end up washed down the drain where they can pass through sewage treatment plant filters and into our oceans and rivers, potentially contaminating our food and water supplies. Nanomaterial can also be applied directly to ecosystems in order to clean up other unwanted pollutants”, he said.

“The use of these tiny particles of metal and chemicals is quite new and we still don’t know whether they’re dangerous and how, or if, we can clean them up.”

He says the world needs to urgently begin preparing to regulate and, if necessary, restrict the widespread use of nanomaterials.

“In the past we used many chemicals in agriculture and industry, only to find out afterwards they were damaging to human health and the environment. We do not want to make the same mistake with nanotechnologies – releasing unknown materials that turn out to be toxic and then finding they are difficult or even impossible to recall or make safe,” said Dr Vanek.

Dr Vanek and his team are one of the first groups in the world to show that ‘nanopollution’ can harm plants. They tested commonly used nanoparticles - titanium dioxide, zinc peroxide, aluminium oxide, fullerenes and carbon graphite fibres - on tobacco plant cells and found that at varying levels the molecules were toxic to the plant.

“This is a new area of research and much more study is required, but we need to understand whether nanoparticles are dangerous to the environment that we can create guidelines to safely use them,” said Dr Vanek.

Dr Vanek believes a lot more research also needs to go into ways to remediate ‘nanopollution’, in order to safely and sustainably manage the technology.

“If we are going to keep using nanoparticles we need to know whether we’re putting ourselves and the environment in danger, and if so, how to minimise it,” said Dr Vanek.

Adelaide latest victim of global water shortages

Australia's fifth-largest city could be reliant on bottled water as early as next week as overuse and drought stretch the Murray River to its limit
Toni O'Loughlin and John Vidal, guardian.co.uk 28 Sep 09;

The water in Australia's biggest river is running so low and is so salty that the nation's fifth-largest city, Adelaide, is at risk of having to ship water in to its residents, politicians have warned.

Adelaide's water crisis follows similar problems in cities around the world, as the combination of growing population, increasing agricultural use and global warming stretches resources to the limit. Experts are warning of permanent drought in many regions.

Salinity levels in some stretches of the Murray River already exceed the World Health Organisation's recommendations for safe drinking, and South Australia's water authority and 11 rural townships east of Adelaide have been told to prepare for the worst.

"Another dry year will deplete our reservoirs and the water in the Murray will become too saline to drink. We are talking about 1.3 million people, who are not far off becoming reliant on bottled water. We are talking a national emergency," said South Australian MP David Winderlich.

As early as next week, water from parts of the river may become too dangerous to drink, which would require the water authority to begin delivering supplies to hospitals, clinics, aged care facilities and local supermarkets in plastic bottles, said Winderlich.

"There's simply too many people pulling water out of the river," said Roger Strother, Coorong council mayor. "We've been saying that one day it would catch up, and this summer is when it is going to happen. It could be next week."

Recent rains have topped up Adelaide's dams, but only enough for one year, and the Murray-Darling Basin Authority, which oversees water use across the whole of south-east Australia, says water levels in reservoirs are much lower than expected. Today the authority said the whole basin was at 25% capacity.

Australia's worst drought in a century has lasted over 10 years in places, and many cities have had to restrict water use.

Climate experts fear the continent faces a permanently drier future as the impact of global warming kicks in. South Australians have watched the waters stagnate as farmers, especially cotton and rice growers upstream, siphoned up to 83% of the water from the river system.

The WHO says the acceptable level of salinity for safe drinking water is 800 EC (electrical conductivity) units but the salinity in parts of the Murray is now around 1,200 EC units. The water authority says it will begin shipping water when the salinity rises to 1,400 EC units.

Adelaide is one of many cities around the world facing acute water shortages as populations grow, long-term droughts continue and ground water is not replenished. The Chinese water minister, Chen Lei, today told engineers at a water conference that two-thirds of Chinese cities now face serious shortages due to rapid industrialisation and climate change.

"Compared to 1956-79, the average rainfall has dropped 6% in three major river basins," Lei said. "Most parts in the north of China are now facing water shortages problems, especially because of the increasing influence of climate change and the faster speed of industrialisation and urbanisation."

By 2015, Lei said, water efficiency would have to be increased by 30%. "Water abstraction must be strictly controlled. We should have strict management of groundwater exploitation and consumption, put a limit on total use of groundwater, and ban or set quotas on groundwater exploitation. Nearly two out of three cities are facing water shortages, and the farmland affected by drought reaches nearly 15m sq km a year."

According to a new UN environment programme report, perennial drought conditions are developing in south-eastern Australia and south-western North America. "Projections suggest that persistent water scarcity will increase in a number of regions in coming years, including southern and northern Africa, the Mediterranean, much of the Middle East, a broad band in central Asia and the Indian subcontinent," the report said.

"There is growing concern that thresholds or tipping points may now be reached in a matter of years or a few decades, including dramatic changes to the Indian subcontinent's monsoon rains, the Sahara and west Africa monsoons, and climate systems affecting the Amazon rainforest," it said.

Hopes in some countries that an El Niño weather event would bring rain to parched areas of the US this week declined as the US government climate prediction centre said temperatures in the equatorial Pacific had stopped climbing. During strong El Niños, abnormally warm waters in that region pump heat and moisture into the atmosphere, which leads to intense storms.

Cities around the world under water stress
BEIJING: Most of Beijing's water comes from the Miyun reservoir, but a decade of drought and huge population increase has left extreme shortages. Water diversion projects are helping, but this is depleting resources from other regions. The city must spend $3.5bn (£2.2bn) in the next five years to cope with a population expected to rise to 17 million.

NAIROBI: The city has imposed water rationing, following an acute drought that has affected all Kenya's water catchment areas. River and reservoirs are at historically low levels. Flower farms and export-oriented agriculture are also reducing supplies available to people.

MEXICO CITY: 2009 has been the driest year recorded in the city of 19 million people. Water is rationed and many areas have no piped water for days at a time. The government has imposed fines of up to $1,200 for hosing down cars and sidewalks or watering lawns during daytime hours. Signs warn that the city could run out of water next spring unless residents switch to low-flow showers and toilets, and plug leaks.

GAZA: Water fit for human use will run out in the Gaza strip within 10 years, the Gaza Coastal Municipal Water Utility and UN agencies said this month. Tap water is already salty, and only 5-10% of groundwater is drinkable. Gaza's population is expected to increase to 3 million by 2025.

KATHMANDU: Erratic rainfall and drier winters have left Nepal's capital very short of water. The water company can provide only 160m litres a day but the demand is well over 200m litres. Many households are drilling their own boreholes to extract groundwater with electric pumps, but the water table is sinking approximately 2.5 metres a year and this is not sustainable in the medium term.

4 Degrees Warming "Likely" Without CO2 Cuts: Study

Gerard Wynn, PlanetArk 29 Sep 09;

LONDON - Global temperatures may be 4 degrees Celsius hotter by the mid-2050s if current greenhouse gas emissions trends continue, said a study published on Monday.

The study, by Britain's Met Office Hadley Center, echoed a U.N. report last week which found that climate changes were outpacing worst-case scenarios forecast in 2007 by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

"Our results are showing similar patterns (to the IPCC) but also show the possibility that more extreme changes can happen," said Debbie Hemming, co-author of the research published at the start of a climate change conference at Oxford University.

Leaders of the main greenhouse gas-emitting countries recognized in July a scientific view that temperatures should not exceed 2 degrees above pre-industrial levels, to avoid more dangerous changes to the world's climate.

The IPCC shared the 2007 Nobel Peace Prize for its fourth assessment report, or AR4. One finding was that global temperatures could rise by 4 degrees by the end of the 2050s. Monday's study confirmed that warming could happen even earlier, by the mid-2050s, and suggested more extreme local effects.

"It's affirming the AR4 results and also confirming that it is likely," Hemming told Reuters, referring to 4 degrees warming, assuming no extra global action to cut emissions in the next decade.

One advance since 2007 was to model the effect of "carbon cycles." For example, if parts of the Amazon rainforest died as a result of drought, that would expose soil which would then release carbon from formerly shaded organic matter.

"That amplifies the amount of carbon dioxide that goes into the atmosphere and therefore the global warming. It's really leading to more certainty," said Hemming.

DRASTIC

Some 190 countries will try to reach an agreement on how to slow global warming at a meeting in Copenhagen in December.

Chinese President Hu Jintao won praise for making a commitment to limit emissions growth by a "notable" amount, at a U.N. climate summit in New York last week. Other leaders made pledges to agree a new climate pact.

Temperature rises are compared with pre-industrial levels. The world warmed 0.7 degrees last century, scientists say.

A global average increase of 4 degrees masked higher regional increases, including more than 15 degrees warmer temperatures in parts of the Arctic, and up to 10 degrees higher in western and southern Africa, Monday's study found.

"It's quite extreme. I don't think it's hit home to people," said Hemming. As sea ice melts, the region will reflect less sunlight, which may help trigger runaway effects.

Such higher Arctic temperatures could also melt permafrost, which until now has trapped the powerful greenhouse gas methane, helping trigger further runaway effects, said Hemming.

"There are potentially quite big negative implications."

The study indicated rainfall may fall this century by a fifth or more in part of Africa, Central America, the Mediterranean, and coastal Australia, "potentially more extreme" than the IPCC's findings in 2007.

"The Mediterranean is a very consistent signal of significant drying in nearly all the model runs," said Hemming. A 20 percent or more fall is "quite a lot in areas like Spain already struggling with rainfall reductions in recent years."

Four degrees of warming 'likely'
David Shukman, BBC News 28 Sep 09;

In a dramatic acceleration of forecasts for global warming, UK scientists say the global average temperature could rise by 4C (7.2F) as early as 2060.

The Met Office study used projections of fossil fuel use that reflect the trend seen over the last 20 years.

Their computer models also factored in new findings on how carbon dioxide is absorbed by the oceans and forests.

The finding was presented at an Oxford University conference exploring the implications of a 4C rise.

The results show a "best estimate" of 4C being reached by 2070, with a possibility that it will come as early as 2060.

Richard Betts of the Met Office Hadley Centre described himself as "shocked" that so much warming could occur within the lifetimes of people alive today.

"If greenhouse gas emissions are not cut soon then we could see major climate changes within our own lifetimes," he said.

"Four degrees of warming averaged over the globe translates into even greater warming in many regions, along with major changes in rainfall."

Big burn

The model finds wide variations, with the Arctic possibly seeing a rise of up to 15C (27F) by the end of the century.

Western and southern parts of Africa could warm by up to 10C, with other land areas seeing a rise of 7C or more.

In its 2007 assessment, the Intergovernmental Panel on Climate Change (IPCC) said the average warming by the end of the century would probably lie between 1.8C and 4C (3.2-7.2F), though it did not rule out the possibility of larger rises.

Key to the Met Office calculations was the use of projections showing fossil fuel use continuing to increase as it has done for the last couple of decades.

"Previously we haven't looked at the impact of burning fossil fuels so intensely," said Dr Betts.

"But it's quite plausible we could get a rise of 4C by 2070 or even 2060."

Dr Betts and his colleagues emphasise the uncertainties inherent in the modelling, particularly the role of the carbon cycle.

But he said he was confident the findings were significant and would serve as a useful guide to policymakers.

The presentation at Oxford's Environmental Change Institute came as negotiators from 192 countries were gathering in Bangkok for the latest set of prepatory talks in the run-up to December's UN climate summit.

Major governments of developing and industrialised nations are committed to a deal that would keep the global temperature rise to 2C, which many regard as a threshold for "dangerous" climate change.

FACTBOX: Key Issues On The Table At Bangkok Climate Talks

PlanetArk 29 Sep 09;

Delegates at U.N. climate talks in Bangkok are trying to whittle down a complex negotiating text that will form the basis of a broader global pact to curb the pace of climate change.

The two-week talks are crucial because negotiators have very little time to trim the options and alternative wording proposals in the 180-page text with just over two months to go before a December 7-18 climate meeting in Copenhagen.

The United Nations has set the Copenhagen gathering as the deadline to try to reach a broad agreement on a replacement pact for the Kyoto Protocol.

Following are some of the main issues being discussed in Bangkok.

FINANCING

This is the glue that will hold any new pact together. Developing nations are demanding rich countries offer new and substantial annual funds to help them adapt to climate change and to help them green their economies without sacrificing growth.

Failure by rich nations to implement immediate, far-reaching actions to cut their emissions would only increase the need for poorer countries to adapt to the impact of climate change and therefore increase costs, the text says.

Poorer nations as well small-island states are seen as the most vulnerable to greater extremes of weather, rising seas and changes in rainfall patterns.

Estimates for long-term financing are in the hundreds of billions of dollars a year but as yet no firm amounts have been pledged in the negotiations by individual countries. That is expected to come in the final hours of the Copenhagen talks.

Nor is it clear how much of the money will be public funds or come from revenue generated by carbon markets or other sources.

The rules governing the allocation of funds have also not yet been decided, nor have governments agreed to beef up existing institutions or create new ones to manage the money and low-carbon programmes.

STRUCTURE FOR ALL NATIONS

Any post-Kyoto agreement will need to include steps by big developing nations such as India and China to curb emissions and to help them acquire technology to substantially cut emissions.

But developing nations won't accept binding emissions targets and have instead pledged to take a range of voluntary steps mandated by their governments, such as energy efficiency and renewable energy programmes.

Negotiators in Bangkok will be focused on designing what they call a legal framework or architecture that will encourage developing nations to sign up.

Kyoto backs economy-wide emissions reduction efforts for rich nations but many developing nations say they won't sign up to such steps in a broader climate pact.

Some nations have proposed a flexible arrangement that allows all nations to set verifiable national action plans to curb emissions. These could be entered into a registry that lists low-carbon strategies.

The idea would be to structure a climate pact that would allow easy amendment of national actions to fight global warming to take into account increased efforts over time.

DEFORESTATION AND DEGRADATION

There's growing interest among many nations to create a scheme that rewards developing nations for saving their forests, which soak up vast amounts of planet-warming carbon dioxide.

The U.N.-backed reduced emissions from deforestation and degradation (REDD) scheme has not yet been integrated into the next climate pact and the number of credits the scheme could generate annually and the value of the credits remain unclear.

A market-based scheme could potentially generate billions of dollars in annual funds for poorer nations from the sales of carbon credits.

Issues surrounding the rules governing the design and monitoring of REDD projects also remain unclear.

UN climate chief says time running out for deal

Rachel O'Brien Straits Times 28 Sep 09;

BANGKOK (AFP) – The UN climate chief warned on Monday that time was running out to break a deadlock on a global warming pact, telling delegates in Bangkok that failure to do so by December would threaten future generations.

The talks are the next to last before a showdown in Copenhagen at the end of the year, when the 192 countries must agree on a treaty for tackling greenhouse gases beyond 2010, after the current Kyoto Protocol expires.

"Time is not just pressing, it has almost run out," said UN climate head Yvo de Boer, who broke down in tears of frustration at talks in Bali two years ago, when world governments drew up the "road map" to the Copenhagen deadline.

After two years of haggling, the world is still trying to thrash out a draft text for December's talks, with major disagreements on the two key issues of cutting carbon emissions and meeting the associated costs.

"There is no plan B, and if we do not realise plan A the future will hold us to account for it," de Boer said in his opening speech to around 2,500 government delegates and representatives from business and environment groups.

De Boer said that devastating floods in the Philippines at the weekend which have killed at least 140 people further highlighted the need for action.

"One of the reasons why countries have gathered here is to ensure the frequency and severity of those kinds of extreme weather events decreases as a result of ambitious climate change policy," de Boer said.

The Bangkok talks, part of the UN Framework Convention on Climate Change (UNFCCC), run until October 9. The final talks before Copenhagen are in Barcelona from November 2-6.

The meeting in the Thai capital follows last week's UN climate summit in New York and a G20 meeting in Pittsburgh, both of which failed to break the deadlock on either of the two biggest issues.

"Our children and grandchildren will never forgive us unless action is taken. Time is running out, we have two months before Copenhagen," Thai Prime Minister Abhisit Vejjajiva said in his opening speech on Monday.

De Boer said on the eve of the Bangkok talks that they had a 280-page negotiating text which is "basically impossible to work with."

The US on Monday reaffirmed its commitment to signing the treaty.

"We want to be part of a new agreement," said Jonathan Pershing, the US head of delegation in Bangkok.

The US -- which signed the Kyoto deal but later saw it rejected by Congress -- is due to introduce its new climate change and energy bill in the Senate this week and there are fears the bill will not pass ahead of Copenhagen.

Pershing said the United States was "working quite aggressively trying to promote action in the Congress."

While the European Union, pegged to a 1990 benchmark, has set a 20 percent target for emissions cuts by 2020, and Japan 25 percent if others follow suit, the US so far has only set the equivalent of four percent as a target.

Experts warn that global temperatures must rise no more than two degrees Celsius (3.6 degrees Fahrenheit) by 2100 over pre-industrial times, a target embraced by the leaders of the G8 nations in July.

Scientists also say emissions of heat-trapping greenhouse gases should peak just six years from now.

Without drastic action they fear drought, floods and rising sea levels could grip the world by the end of the century causing famine, homelessness and strife.

On emissions, developed economies including the US have acknowledged a historical responsibility for global warming. Most have put numbers on the table for slashing their carbon pollution by 2020 and by 2050.

But they say that developing nations -- especially China, India and Brazil and other major emitters of tomorrow -- should also pledge to curb output of greenhouse gases.

Poor and emerging economies refuse to take on their own hard targets but call for rich nations to make higher cuts.

UN warns leaders time running out for climate deal
Michael Casey, Associated Press 28 Sep 09;

BANGKOK – The United Nations on Monday warned world leaders they have only 70 days to reach a new deal to limit global warming, while environmentalists pointed to the deadly floods in the Philippines to illustrate the already devastating impact of climate change.

Only hours after negotiations began, rich and poor nations were already flinging their usual rebukes at one another for failing to do their part to reach a deal to replace the Kyoto Protocol, which expires in 2012.

Talks have been deadlocked for months over the industrial countries' refusal to commit to committing to sufficiently deep cuts or provide billions of dollars to poor nations to help them adapt to the impacts of climate change and transition to a low-carbon economy.

The major developing countries like India and China, in turn, have refused to agree to binding targets altogether and are leery of demands that any of their commitments be monitored and verified as part of any agreement.

"Time is not just pressing. It has almost run out," U.N. climate chief Yvo de Boer said, with a clock nearby showing there were 70 days until world leaders are scheduled to meet in Copenhagen to finalize a pact.

"As many leaders have said, there is no plan B," he continued. "If we don't realize Plan A, the future will hold us to account for it."

Some environmentalists tried to raise the sense of urgency by pointing to the weekend tropical storm that set off the region's worst flooding in more than 40 years in the Philippines and left 140 dead. It offered, they said, a glimpse into the kind of turbulent weather that could be unleashed by warming temperatures.

"We are asking the negotiators to look outside these walls. They should realize that it is the people's lives at stake," said Dinah Fuentesfina, a Philippine activist from the Global Campaign for Climate Action Asia.

The need for a deal was also driven home by a U.N. report last week that showed climate-related events such as the melting of glaciers and polar ice sheets and the increasing acidification of the oceans were happening much faster than scientists had predicted even two years ago.

The two weeks of U.N. climate talks in the Thai capital, the second to last meeting before Copenhagen, have drawn some 1,500 delegates from 180 countries who are tasked with boiling down an unwieldy, 200-page draft agreement to around 30 pages that will be presented to ministers in Denmark.

Connie Hedegaard, the Danish minister for climate and energy whose country will host the talks in December, told delegates the world was watching and urged them to build on the momentum that came out of last week's U.N. climate summit where 100 world leaders pledged their support for an agreement.

At the New York summit, President Barack Obama and Chinese President Hu Jintao — whose countries are the world's two biggest emitters, each accounting for about 20 percent of greenhouse gas pollution — both vowed tough measures to combat climate change.

Hu said China would generate 15 percent of its energy from renewable sources within a decade, and for the first time pledged to reduce the rate by which its carbon emissions rise. He did not give specific targets.

Most countries agree that the rise in average global temperatures must not exceed 3.6 degrees Fahrenheit (2 degrees Celsius) above preindustrial levels — a threshold beyond which it is believed serious climate changes would ensue. Temperatures have already risen 1.4 degrees Fahrenheit (0.8 degrees Celsius) since the 19th century.

But so far, there is no consensus on how to stop the warming

Most industrialized nations have offered to cut emissions 15 to 23 percent below 1990 levels by 2020, falling short of the 25 to 40 percent cuts scientists and activists say are needed to hold off warming of 3.6 degrees Fahrenheit (2 degrees Celsius).

But the United States has offered much lower targets so far, with a House of Representatives bill proposing to reduce emissions by 17 percent from 2005 levels — only about 4 percent below 1990 levels — by 2020. The Senate has yet to take up the climate bill.

De Boer insisted a deal could still be reached in Copenhagen, but the traditional divisions sprang up quickly on the first day as poor countries repeatedly called for deeper emissions cuts from rich nations.

"Emission reductions of at least 40 percent or 45 percent below the 1990 baseline by developed countries are required and must be announced without further delay," the Indian delegation said in a statement.

Sudan's Lumumba Di-Aping, speaking for the Group of 77 developing nations and China, said it was just as important that developed countries financially help poor nations adapt to the impacts of climate change and develop greener economies.

"Finance and technology are central to achieving a just and equitable deal," Di-Aping said.

But the United States shot back that developing countries would have to do their part — short of binding targets — to reduce greenhouse gas emissions and for the first time agree to a system that would monitor and verify their promised actions.

Jonathan Pershing, the chief American negotiator at the talks, said the United States was ready to make a deal but that it would take actions from every nation big and small.

"No one nation can meet this challenge alone," he said.

Negotiators urged to speed up climate pact talks
Thin Lei Win and David Fogarty, Reuters 28 Sep 09;

BANGKOK (Reuters) - Delegates at the start of marathon climate talks in Thailand on Monday were told to speed up "painfully slow" negotiations as they struggle to settle on the outline of a tougher pact to fight global warming.

The Bangkok talks, which run until October 9, is the last major negotiating round before a gathering in Copenhagen in December that the United Nations has set as a deadline to seal a broad agreement on a pact to expand and replace the Kyoto Protocol.

"Time is not just pressing. It has almost run out," Yvo de Boer, the head of the U.N. Climate Change Secretariat, told delegates from about 180 countries.

"But in two weeks real progress can be made toward the goals that world leaders have set for the negotiations to break deadlocks and to cooperate toward concrete progress," he said.

Delegates at the talks are tasked with trying to streamline a draft legal text of a pact that would replace Kyoto. The main text, running to about 180 pages, is filled with blanks, options and alternative wording options.

The U.N.-led negotiations have become bogged down over arguments about rich nations' targets to cut emissions by 2020, financing for poorer nations to adapt to climate change and to curb their own greenhouse gas emissions and the best way to deliver and manage those funds.

"We've talked for long enough, the world expects actions," Connie Hedegaard, Denmark's minister of climate change and energy and host of the December 7-18 Copenhagen gathering, told delegates.

De Boer later told reporters the negotiating process so far had been painfully slow. "We must have a higher level of ambition in terms of emissions cuts by industrialized countries.

"In addition, we need to see more clarity here on how the process is going to make it possible for developing countries to engage," he said.

"DROWNING IN TEXT"

The United Nations, many developing nations and green groups have expressed frustration about the lack of progress during several negotiating rounds in the run-up to Copenhagen.

"The problem we have at the moment in these negotiations is that we are drowning in text," Tove Ryding of Greenpeace told reporters.

"What we need to see is late nights and fights. We need to see them sit there -- that's what these people do for a living -- they need to smell like sweat and coffee. If they don't do that, they're not actually at work."

De Boer spoke of progress at last week's U.N. climate change summit in New York but said a Copenhagen agreement must have five essential elements.

These included enhanced steps to help the most vulnerable nations adapt to climate change impacts, tougher emissions targets for rich nations, which are currently well below the 25-40 percent reductions from 1990 levels by 2020 recommended by the U.N. climate panel, and cash to help poorer countries cut their emissions.

Hedegaard said a picture was beginning to emerge from the puzzle of the climate text, but rapid progress was needed to refine it into a document with clear political choices.

Artur Runge-Metzger, head of the European Commission delegation, said final figures on finance would most likely be decided on the last night of the Copenhagen talks.

"Because you can only commit to figures if you know what kind of deal you are going to have and which direction are you going to go," he said.

De Boer said long-term financing to help poorer nations adapt to climate change and to slow the pace of their emissions growth should be in the hundreds of billions of dollars per year.

"I think the main worry for us here in Bangkok is that there's only 70 days left," said Runge-Metzger, referring to the start of the Copenhagen meeting. "There's so much work to be done."
