Netherlands to strengthen flood fortifications

Yahoo News 18 Dec 08;

THE HAGUE (AFP) – The Dutch government on Thursday unveiled a multi-billion dollar plan to reinforce dykes and the coastline and augment fresh water supplies in the face of rising sea levels due to global warming.

Two-thirds of the Netherlands lies below sea-level and the country is increasingly worried about the threat of devastating floods.

The government's national water plan proposes strengthening hundreds of kilometres (miles) of dykes along the North Sea, adding massive sand deposits to the coast, increasing river drainage capacity, and expanding the freshwater Ijsselmeer (lake) north of Amsterdam.

"The Netherlands has good fresh water provision, but it won't always be guaranteed," said a government statement, warning about the "intrusion" of salt water due to the rising seas.

Highlighting the need to also take advantage of abundant water, the government said a windmill park in two areas of the North Sea should be built to generate 6,000 megawatts of energy by 2020.

They will reportedly be able to generate as much energy as six coal-fired power stations.

Nine million people from a population of 16 million live in inland areas directly sheltered from the sea and rivers by dykes and dunes.

Sixty-five percent of the national production capacity lies in flood-prone areas.

The plan, presented to parliament on Thursday, also moots the possibility of creating an artificial island in the North Sea for energy storage and production.

A government-appointed commission said in September that the Netherlands would have to spend more than 100 billion euros (143 billion dollars) over the next century on dyke upgrades and coastal expansion to avoid flood damage resulting from global warming.

Once passed by parliament, the plan will be incorporated into a national water law.

In 2007, fortification measures against water cost the country a total of five billion euros.

Three Gorges Dam Tested As Water Rises

Ian Ransom, PlanetArk 19 Dec 08;

BEIJING - Rising water levels in China's giant Three Gorges Dam have triggered dozens of landslides in recent months, damaging houses, land and infrastructure worth millions of dollars, state media said on Thursday.

In July, China finished evacuating residents from the last town to be submerged by the massive 660-km (400-mile) long reservoir on the Yangtze River, ending an exodus of some 1.4 million people that began four years ago.

The 2,309-meter-long dam, the world's largest, aims to tame the river and provide cheap, clean energy for the country's rapid development.

But critics say rising water levels in the reservoir are eroding already fragile slopes and triggering landslides which could worsen as levels reach their maximum height next year.

The reservoir's administration began withholding water outflows in September to push the reservoir's water level up to 175 meters.

But since then, the rising water level had "further induced geological harm including landslides and collapsing of the reservoirs' banks," the Xinhua news agency quoted Chongqing government spokesman Wen Tianping as saying.

"(These) have caused damage or created a latent threat to ... infrastructure, land and housing in dam areas above the evacuation line," Wen said.

He added that 93 "surface threats" had emerged in 12 regions and counties around the dam area, causing direct losses of 360 million yuan ($53 million), but had not caused any injury or loss of life.

He however said the problems were anticipated during the dam's feasibility study and that there was no cause for concern.

Officials said last year 12 billion yuan ($1.75 billion) had been spent on repairs around the massive dam in past years and were confident such efforts were successful.

But in April, a large mudslide hit a village in the Gaoyang area near the dam in April, sweeping into a school playground. A landslide nearby killed 35 people late last year.

Finished in 2003, the dam's water level has risen in stages, reaching 156 meters in 2006. It is expected to reach its final height next year.

China cull amid bird flu outbreak

BBC News 17 Dec 08;

More than 370,000 chickens have been culled in China's eastern province of Jiangsu after an outbreak of the H5N1 strain of bird flu, say officials.

The outbreak is thought to be the first in mainland China since June.

Meanwhile, a man has reportedly contracted the virus in Cambodia, while Taiwan is investigating suspected infection among birds.

The death of a teenage girl from H5N1 was announced in Egypt on Tuesday, and a bird cull is also under way in India.

More than 200 people in a dozen countries have died of the virus since it resurfaced in Asia in 2003, say global health authorities.

Experts fear that the virus could mutate into one that is easily transmissible from human to human.

Migrating birds blamed

China's Ministry of Agriculture said it received notification that the H5N1 virus had been found in two areas of Jiangsu on Monday.

The usual precautions have been imposed: birds have been slaughtered in the surrounding area, farms quarantined and disinfected, and the transport of fowl banned.

But no information has been released about the scale of the outbreak - how many birds were found to be carrying the H5N1 strain of the virus and how many of them died.

Officials say they think migrating birds might have been the source of the disease.

They are currently testing samples of the virus to check it has not mutated into a form that would pose a risk to human health, reports the BBC's Chris Hogg in Shanghai.

Virus returns

China is among a number of countries experiencing a return of the virus this season:

• Authorities in the Indian state of West Bengal are implementing a cull after tests on poultry from two villages yielded positive results

• In Cambodia, another cull is under way after the World Health Organisation (WHO) and government confirmed a young man had the virus, according to Reuters news agency

• Authorities in Taiwan say they are investigating the cause of the sudden death of poulty in Luzhu, Kaohsiung county, Reuters says

• Earlier in the week, Egyptian authorities announced the death of a 16-year-old girl from the virus

• The discovery of infected birds in Hong Kong last week sparked a cull of more than 80,000 birds


WHO warning

The WHO recently warned governments in Asia not to let down their guard against bird flu.

Some experts fear that because the virus has not yet mutated into a form that could spread easily among humans, the fight against bird flu is seen as less of a priority than before.

Countries like China - with huge densely populated cities and in many places only basic healthcare and veterinary services - are thought to be particularly vulnerable should the virus become more deadly, says our correspondent Chris Hogg.

Nasa set to launch 'CO2 hunter'

Jonathan Amos, BBC News 18 Dec 08;

The US space agency is set to launch a satellite that can map in detail where carbon dioxide is in the atmosphere.

Nasa's Orbiting Carbon Observatory (OCO) will pinpoint the key locations on the Earth's surface where CO2 is being emitted and absorbed.

CO2 from human activities is thought to be driving climate changes, but important facts about its movement through the atmosphere remain elusive.

The agency believes the technology on OCO can end some of the mysteries.

"This is Nasa's first spacecraft specifically dedicated to mapping carbon dioxide," principal investigator David Crisp told BBC News.

"The objective of the OCO mission is to make measurements that are so precise that they can be used to look for surface 'sources' and 'sinks' of CO2."

Dr Crisp has been presenting details of the mission here at the American Geophysical Union's (AGU) Fall Meeting.

As he did so, OCO's launch on a Taurus XL rocket from Vandenberg Air Force Base in California was booked for 23 February.

Nasa already has a CO2 detection instrument on its Aqua satellite but this looks at the greenhouse gas some five to 10km above the surface.

OCO, on the other hand, will detail the concentration of carbon dioxide close to the ground where its warming effect is most keenly felt.

The observatory will be engaged in what amounts to carbon accountancy. Its fortnightly global maps of CO2 concentration will help the mission team work out where the gas is entering the atmosphere and where it is being absorbed by land plants and the oceans.

Scientists have calculated that nature cycles about 330 billion tonnes of carbon every year.

Human activities put about 7.5 billion tonnes into the atmosphere - a tiny sum in comparison but enough, say researchers, to imbalance the system and raise the global mean surface temperature of Earth.

"We know where most of the fossil fuel emissions are coming from; we also know where things like cement manufacturing are producing large CO2 emissions," explained Dr Crisp, who works at Nasa's Jet Propulsion Laboratory.

"But there are other things such as biomass (forest) burning and clearing; and we don't have a good quantification of the CO2 released by those processes.

"If you take out the fossil fuels - for which we understand the CO2 source to within 10% - and look at the rest of the carbon dioxide that's introduced into the atmosphere by our activities, it's uncertain by 100%.

"The idea is that OCO will help us to constrain that a whole lot better."

Location, location

The sinks for CO2 - the places where it is absorbed - also have many mysteries associated with them.

The Earth is thought to be absorbing about 50% of the carbon dioxide we put out - the majority of it going into the oceans. But science's description of the other major absorbers is poor, commented UK Earth-observation scientist Shaun Quegan.

"There's a bunch of atmospheric collection flasks dotted around the planet and when we apply the models to their data, the models all show there is a carbon sink in northern mid-latitudes," he said.

"But whether that's in North America, in Siberia, or wherever and what's causing it is a big debate."

Since science does not have a good handle on where the CO2 is being absorbed, researchers can have only limited understanding of how CO2 sinks are likely to evolve as the climate changes.

"Let's say we found that the boreal forests in Canada and Siberia were the primary sinks of CO2 because of their incredibly rapid growth during summer months when the Sun is up," speculated Dr Crisp.

"Well those environments are changing dramatically right now.

"Will they still be the primary absorbers of CO2 as time goes on? We don't really know how big an impact they're having right now.

"This is why OCO is so essential."

Reflected glory

The observatory carries a single instrument - a spectrometer that breaks the sunlight reflected off the Earth's surface into its constituent colours, and then analyses the spectrum to determine how much carbon dioxide and molecular oxygen is present.

The data can be used to work out atmospheric concentrations.

OCO will map carbon dioxide over 1,600-sq-km (620 sq miles) regions of the Earth's surface to an accuracy of just fractions of 1%.

However, to locate the sources and sinks, scientists will need to combine the information with models that estimate how CO2 is being moved and mixed through the air.

Once in orbit, OCO will join a fleet of other satellites - known as the A-Train - which carry a range of instrumentation to give a rounded picture of Earth's atmospheric and water systems.

The spacecraft cross the equator in the early afternoon on a path that takes them over broadly the same observation point in quick succession.

OCO will be followed into orbit next year by a Japanese carbon mission known as the Greenhouse gases Observing SATellite (GOSAT).

Europe is considering two carbon observatories - A-SCOPE (Advanced Space Carbon and Climate Observation of Planet Earth) and a mission called BIOMASS - which could fly in 2016.

Professor Quegan, from the UK's University of Sheffield, is working on the BIOMASS proposal.

"The spacecraft would measure global forest biomass at scales of about one hectare," he said.

"It's a crucial natural resource and ecosystem service - for materials, for energy, for biodiversity - there's a good correlation between how much biomass you've got and how much biodiversity you've got - and for climate and water protection."

"So from a carbon cycle science aspect, forests have some critical parameters that need to be pinned down."

Tidal energy system on full power

BBC News 18 Dec 08;

A tidal turbine near the mouth of Strangford Lough has begun producing electricity at full capacity for the first time.

The SeaGen system now generates 1.2MW, the highest level of power produced by a tidal stream system anywhere in the world.

The system works like an "underwater windmill" but with rotors driven by tidal currents rather than the wind.

It has been undergoing commissioning trials since May.

SeaGen will now move towards full-operating mode for periods of up to 22 hours a day, with regular inspections and performance testing carried out.

The power generated by the system is being purchased by Irish energy company, ESB Independent, for its customers in Northern Ireland and the Republic.

The turbine has the capacity to generate power to meet the average electricity needs of around 1000 homes.

Martin Wright, managing director of SeaGen developers, Marine Current Turbines, said that having the system generating at full power was an important milestone.

"It demonstrates, for the first time, the commercial potential of tidal energy as a viable alternative source of renewable energy," he said.

"As the first mover in tidal stream turbine development, we have a significant technical lead over all rival tidal technologies that are under development.

"There are no other tidal turbines of truly commercial scale; all the competitive systems so far tested at sea are quite small, most being less than 10% the rotor area of SeaGen."

Swiss engineer completes first world tour in solar-powered car

Yahoo News 18 Dec 08;

GENEVA (AFP) – A Swiss engineer completed Thursday the first ever round-the-world trip in a solar-powered car after more than 17 months on the road during which he crossed almost 40 countries.

Louis Palmer, 36, arrived back in Lucerne in central Switzerland in his "solar taxi" after covering 53,451 kilometres (33,213 miles) over four continents.

Since his departure on July 3 2007, he travelled through eastern Europe, the Middle East and India before heading to New Zealand, Australia, southeast Asia and China and finally the United States.

He finished his trip after a detour through France, England, Scandinavia and Germany.

"We have achieved our first world tour without using a single drop of oil," Palmer rejoiced at the end of his trip.

The three-wheeler solar taxi, which towed a trailer packed with batteries charged by the sun, reached speeds of 90 kilometres (55 miles) per hour. It had a battery for travel in the night and in cloudy conditions.

"One of my goals was to persuade as many people as possible that renewable energy is ecological, economical and reliable," Palmer told reporters.

His vehicle only broke down twice during the tour, he said, and surmounted the extreme heat in the Middle East and the hazardous terrain in America's Rocky mountains.

The small blue-and-white vehicle carried around 1,000 passengers, including United Nations Secretary General Ban Ki-moon and Rajendra Pachauri, head of the Nobel-winning Intergovernmental Panel on Climate Change (IPCC).

Palmer has previously said the prototype for the solar taxi could be mass produced but that it would need serious modifications.

He said he plans to travel around the world in 80 days for his next challenge, but in a faster car.

Coal Should Be Warming Concern: Scientists

Clare Baldwin, PlanetArk 19 Dec 08;

SAN FRANCISCO - Researchers and officials concerned about global warming have focused on oil usage, but scientists on Wednesday said liquefied coal could have a greater affect on global climate change.

Global warming scenarios are based on oil reserves, but those reserves will have less impact on global climate than the extent to which liquefied coal replaces oil and gas, scientists said at a meeting of the American Geophysical Union in San Francisco.

"Oil and gas by themselves don't have enough carbon to keep us in the dangerous zone for very long by themselves, but that's assuming we do something about coal," Pushker Kharecha, a researcher for the U.S. space agency NASA and Columbia University in New York.

Estimates vary, but coal is the most abundant fossil fuel, and countries like China and the United States are looking at liquefaction technology. Many industries in South Africa already use liquefied coal.

In 2007, Illinois Democratic Sen. Barack Obama and Kentucky Republican Jim Bunning introduced legislation that would set the stage for large-scale production of transportation fuels from coal. Bunning and president-elect Obama come from state with prodigious coal supplies.

Liquefied coal releases 40 percent more carbon dioxide than oil when burned, said Ken Caldeira, a scientist at the Carnegie Institution of Washington.

"Addressing the climate problem means addressing the coal problem," he said. "Whether there's a little more oil or a little less oil will change the details, but if we want to change the overall shape of the warming curve, it matters what we do with coal."

ELEVATED LEVELS OF CARBON DIOXIDE

Caldeira said his climate models show that if all oil used in the world is replaced with liquefied coal, global temperatures will rise 2 degrees Celsius (3.6 degrees Fahrenheit) by 2042, three years sooner than if oil remains a staple.

If oil is replaced with solar, wind, or nuclear power, temperatures will rise 11 years later.

Many scientists believe high levels of atmospheric carbon dioxide lead to warming and effects like melting glaciers, thawing permafrost, ocean acidification and latitudinal shifts in climate.

Current atmospheric carbon dioxide levels are 385 parts per million and rising at a rate of about 2 parts per million (ppm) year as a result of burning coal, oil, and gas, the researchers said.

The generally accepted threshold for atmospheric carbon dioxide is 450 ppm. But scientists today said that number should be 350 ppm.

Climate change is a slow process, Kharecha said, and the effects may take decades and centuries to show up.

"There are currently more than enough fossil fuels and coal to push us well past safe atmospheric CO2 levels," he said.

None of the models presented at the session included carbon dioxide emissions from unconventional fossil fuels like tar sands, methane hydrates or oil shale.

Representatives from the liquefied coal industry could not be immediately reached for comment. In February, Robert Kelly of DKRW Advanced Fuels, which is building a liquefied coal production facility in Wyoming, told Reuters, "liquefied coal could be a huge fuel source for the next 50 years if we do it responsibly." He said coal emissions could be safely captured and stored underground.

Climate outcome 'hangs on coal'
Jonathan Amos, BBC News 19 Dec 08;

If growth in carbon dioxide emissions is to be constrained and even reversed then the world cannot afford a coal renaissance, scientists have said.

Some commentators have argued that falling reserves of oil and gas will automatically limit CO2's rise.

But at an American Geophysical Union meeting, researchers said reserves of coal dwarfed those of other fuels.

It was even possible oil's demise could trigger an acceleration in emissions through more coal use, they added.

"We can replace oil with liquid fuels derived from coal," said Ken Caldeira from the Carnegie Institution at Stanford University in California.

"But these liquid fuels emit even more carbon dioxide than oil, so the end of oil can mean an increase in coal and even more carbon dioxide emissions to the atmosphere, and even more rapid onset of dangerous climate change."

Professor Caldeira's group has used climate and carbon cycle models to look at how future emissions and temperature projections would be altered by different fuel strategies.

The team tried to work out the maximum effects that would arise from replacing oil either entirely with coal-based liquid substitutes or entirely with renewable energy sources.

The assessment found that if coal-derived liquids are adopted, the Earth would achieve a 2C rise in temperature from pre-industrial times (a figure sometimes quoted as being a desirable ceiling to stay beneath in order to avoid "dangerous climate change") by 2042. This is three years faster than a business as usual future with oil.

If the renewables strategy is adopted, the 2C figure is not reached until 2056.

"Clearly, to address the climate issue we have to address the coal issue," Professor Caldeira told BBC News.

His assessment was shared by Pushker Kharecha from Nasa's Goddard Institute for Space Studies (Giss).

"We cannot move into things like coal-to-liquids and unconventional fossil fuels such as methane hydrates, tar sands, oil shale and so forth," he said.

"If they become large-scale substitutes for oil and gas, that would worsen things because they are much dirtier than oil and gas because they produce more emissions per unit energy delivered."

Reserve judgement

Dr Kharecha presented details of recent research from the US, UK and France looking at the feasibility of not only constraining the growth of CO2 emissions but actually reducing its concentration in the atmosphere to 350 parts per million by volume (it is currently up at about 385ppmv).

The group found it was possible, but only with a prompt moratorium on new coal use that does not capture CO2, and a phase out of existing coal emissions by 2030.

Reforestation together with improved agricultural practices could help draw down CO2.

"Efficiency and conservation have huge potential to offset emissions in the near term," Dr Kharecha told BBC News.

"And then in the mid-term and long-term we can focus on moving to alternatives such as renewable energies, and possibly a balanced look at nuclear because it does provide many benefits in addition to the numerous problems that it poses."

A new analysis presented here puts the total available global coal reserves at 662 billion tonnes.

The figure is substantially lower than the ones used in assessments by the Intergovernmental Panel on Climate Change (IPCC) to gauge possible future emissions scenarios.

"This is a radically different number from what is conventionally assumed," said Professor David Rutledge from the California Institute of Technology, who led the analysis.

"The IPCC assumes that about five times as much coal is available for burning."

But the scientists at this meeting said that if burnt, even this smaller amount of coal would radically alter the climate unless all the emissions were captured and stored.

"There is far more than enough currently useable coal and other fossil fuels to push us past the threshold beyond which we would not want to go with the climate," Dr Kharecha said.

Asean Addresses Climate Change, Food Security

Bernama 18 Dec 08;

JAKARTA, Dec 18 (Bernama) -- Asean is making a move towards elaborating a regional strategy on agriculture, forestry and fisheries in order to address the global issue of climate change.

This follows the global commitment and response to climate change agreed at the recent UN Framework Convention on Climate Change Conference in Poznan, Poland.

The fourth ASEC Brown Bag Series by the Asean Secretariat today titled "Climate Change and Food Security: Challenges for Asean", highlighted the need for strategic planning and policy coordination in Asean to address the complex and interrelated issues of food security and climate change.

Guest speakers were Dr Wulf Killmann, chairman of the Food and Agriculture Organisation of the United Nations' (FAO) Interdepartmental Working Group on Climate Change and director of the Forest Products & Industries Division of FAO's Forestry Department, and Dr Irsal Las, head of the Indonesian Center for Agricultural Land Resources Research and Development.

Dr Killmann pointed to the interrelation of climate change, food security and forestry and underscored that inter-sectoral coordination was required to meet changing and more difficult environmental conditions.

"Societies will have to weigh trade-offs between land-uses," he said, concluding that climate change could only be dealt with in an integrated manner through integrated land-use policies and implementation at local, national, regional and international levels.

Dr Las called for collaborative research and regional strategy development in Asean, including the agriculture, forestry and fisheries sectors to address the impact of climate change effectively.

"The impact of climate change to agriculture has broadened and therefore requires a holistic strategy to this situation. Climate change is a trans-boundary issue, so policy coherence, knowledge-oriented policy-making as well as mutual learning and common understanding among Asean member states are crucial to this end," he said.

Meanwhile, the principal director of the Bureau for Economic Integration and Finance at the Asean Secretariat, S. Pushpanathan said Asean through its ministers for agriculture and forestry had adopted a strategic plan of action on Asean food security where linkages with climate change were emphasised.

"Asean is also committed to pursuing a regional plan to elaborate measures in dealing with mitigation and adaptation to climate change on agriculture, fisheries and forestry that will lay the foundation for tackling important and interrelated issues of climate change, including food security," he said.

More ASEC Brown Bag Series on contemporary topics of interest to Asean will be organised in the coming months as the Asean Secretariat intensifies its public outreach efforts to promote the Asean Community and the work of Asean.

Scientists predict severe bleaching in the Great Barrier Reef

The Sydney Morning Herald 18 Dec 08;

Northern parts of the Great Barrier Reef is likely to suffer severe coral bleaching this summer, the conservation group WWF Australia warns.

A report from the US government's National Oceanic and Atmospheric Administration forecasts severe bleaching for parts of the Coral Sea, the Coral Triangle and the reef, WWF said.

The Coral Triangle is home to 75 per cent of all known coral species and covers waters from the Philippines to Malaysia and Papua New Guinea.

WWF's climate change expert Richard Leck said the bleaching would impact on tourism, food supply and livelihoods in northern Queensland and South East Asia.

"The bleaching, predicted to occur between now and February, could have a devastating impact on coral reef ecosystems, killing coral and destroying food chains," Mr Leck said.

"There would be severe impacts for communities in Queensland, Australia and the region, who depend on the oceans for their livelihoods.

"More than 120 million people rely on its marine resources."

He said there would be significant impacts on Cairns and Port Douglas where the reef's tourism was centred.

Large scale coral bleaching was expected to happen regularly if average global temperatures rose at least two degrees Celsius.

Mr Leck said the latest data showed how important it was for Australia to reduce its greenhouse gas emissions.

The WWF and many other environmental groups have condemned the Rudd government's carbon pollution reduction scheme as weak.

The government this week announced a 2020 carbon reduction target of at least five per cent, but was open to a higher target if a global consensus could be reached.

Hot summer will bleach Coral reef
Jennifer Macey, ABC News 19 Dec 08;

TONY EASTLEY: Predictions of a long hot summer may please many Australians but it's not good news for one of the country's top tourist attractions.

There's a high risk the Great Barrier Reef will suffer severe coral bleaching with sea temperatures expected to be above average.

Meteorologists in the US and Australia have used satellites to predict the death of corals in the Great Barrier Reef and in the Coral Sea.

Jennifer Macey reports.

JENNIFER MACEY: It's only the start of summer but satellite images show sea surface temperatures in the Coral Sea are already higher than average.

The Bureau of Meteorology and the American National Oceanic and Atmospheric Administration have both forecast a high risk of coral bleaching this summer.

Dr Russell Reichelt is the chairman of the Great Barrier Reef Marine Park Authority.

RUSSELL REICHELT: They're likening the conditions that we're looking at this summer now to be same as they were in 1998 when a very large global event occurred where 16 per cent of world's coral reefs died from coral bleaching.

JENNIFER MACEY: Ten years ago, half of the Great Barrier Reef was affected by coral bleaching but only five per cent suffered permanent damage.

Dr Reichelt says reefs can recover from bleaching if they don't face further stresses from pollution, over-fishing or repeated hot weather events.

RUSSELL REICHELT: Things like poor water quality running off the land should be cleaned up. Things like damaging corals from anchoring on corals should be prevented. We want a healthy reef to be able to withstand the pressures that are happening from the global warming.

JENNIFER MACEY: Professor Terry Hughes is the director of the Australian Research Council Centre for Excellence for Coral Reef Studies. He says if the warmer temperatures last for more than two months there's a serious risk of coral dying.

TERRY HUGHES: If you lose the structure that the corals provide through their skeleton then fish populations inevitably decline as well.

JENNIFER MACEY: He says bleaching is a clear sign of global warming.

TERRY HUGHES: It's important to remember that for coral reefs, global warming is not some distant threat that might or might not happen in the future. It's already happening. So the Great Barrier Reef has already bleached twice and there's a very good chance that this year will be the third major bleaching event to impact on the Great Barrier Reef.

JENNIFER MACEY: Environment groups accuse the Federal Government of ignoring the reef in its response to climate change this week.

Richard Leck is from the Conservation group WWF Australia.

RICHARD LECK: What would be a horrible irony of the release of the emissions trading system targets this week would be to see a taste of things to come in the future, of more severe and frequent bleaching events. And that's what will happen unless we get action on climate change - significant reductions, not five per cent reductions.

JENNIFER MACEY: Marine biologist Professor Terry Hughes agrees.

TERRY HUGHES: We've got to sharply reduce CO2 emissions and if we don't do that then we will lose the Great Barrier Reef. We've got 10 to 15 years to significantly reduce CO2 emission. We need to do better.

JENNIFER MACEY: But scientists stress that a cyclone or winds that may cool water temperatures could also prevent a major bleaching event this summer.

TONY EASTLEY: Jennifer Macey.

Chilling developments in Dubai

A refrigerated swimming pool and an artificially cooled beach - Dubai's latest excesses are enough to make conservationists weep. Leo Hickman reports

Leo Hickman, The Guardian 18 Dec 08;

There will surely come a day when Dubai runs the world's reserves of hyperbole dry. But in the meantime, we continue to draw a sharp intake of breath each time a new construction project is announced. We have had ski domes built in the desert, seen vast artificial islands rise from the sea and watched several structures vying for the title of world's tallest building. Dubai represents the will, vision and ambition of our species. Yet many believe it shines an unflattering light on our tendency for folly and hubris, too.

This week, it was reported that the Palazzo Versace hotel - the Emirate's latest offering for those still in the market for exorbitant luxury - will boast, when completed in 2010, a refrigerated 820sq metre swimming pool and a beach with artificially cooled sand to protect its guests from the excesses of a climate that can see summer temperatures exceeding 50C. Wind machines will even be on hand to provide a gentle breeze.

"We will suck the heat out of the sand to keep it cool enough to lie on," said Soheil Abedian, founder and president of Palazzo Versace, a hotel group with plans for a further 15 luxury hotels around the world to add to the one that already exists on Australia's Gold Coast. (I'm a Celebrity junkies will know this as the hotel where the celebrities are sent once voted out of the "jungle".) "This is the kind of luxury that top people want," he added.

The energy required to run this project can only be guessed at (when questioned, Hyder Consulting, the British company hired by the hotel to build these facilities, said it has signed a confidentiality agreement with Palazzo Versace and therefore couldn't comment), but it is likely to leave the world's environmentalists with their heads in their hands. First there is the energy required to power giant wind machines all day long, not to mention the electricity needed to pump coolant around tubes laid under the sand. However, the most energy-intensive element of this plan is likely to be the power needed to refrigerate a whole swimming pool under Dubai's baking sun.

Of course, in a place like Dubai, this kind of audacious project goes relatively unnoticed, among the many others currently underway. To pick just one other example, 30,000 mature trees are scheduled to be shipped to Dubai to help landscape a new Tiger Woods-designed golf course that will be bordered by "22 palaces and 75 mansions". Even without the twin threats of climate change and a global economic recession, Dubai's grandiose plans might seem short-sighted to some. Is it really wise to be building at all, let alone on this scale, in a place that the United Nations describes as one of the most "water-imperilled" environments on the planet, but where per capita water use is three times the global average?

"It's grotesque that while the world's poorest people face the loss of their homes and livelihoods, as well as disease and starvation, because of climate change, the world's richest people think it's acceptable to waste precious energy so pointlessly on things such as artificially cooled beaches," says Robin Oakley, head of climate and energy at Greenpeace UK. "While Abu Dhabi, like Barack Obama, is betting on green technology as the engine for growth this century and even building a zero-emissions city, Dubai is apparently still stuck in the 1980s."

Dubai's ruling elite insists it now places "sustainability" at the heart of its plans for existing and future projects. Last year, Sheikh Mohammed bin Rashid Al Maktoum, Dubai's ruler, spelled out the "Dubai Strategic Plan 2015" in a speech. He explained that oil now contributes only 3% to Dubai's GDP and that his plan is to "sustain Dubai's environment, ensuring that it is safe and clean". Each new construction project now boasts a paragraph in its brochure about how it will "follow environmental best practice", but even if these new measures do materialise, Dubai is a place built on the ideology and convenience of cheap, free-flowing oil. Its business model, particularly its ever-expanding tourist sector, is based on the premise that people will always be willing and able to fly long distances to get there. (Some airlines now euphemistically describe Dubai as both a "long short-haul" destination and a "long-haul weekend break destination".) A new six-runway mega airport is being built to serve a predicted capacity of 120 million passengers a year.

These latest plans for an artificially cooled beach may be causing ripples around the world, but why isn't there more vocal opposition by environmentalists within Dubai? The simple answer is there are no environmentalists in Dubai; not in the sense of a campaigning, placard-bearing activist that you might find elsewhere. NGOs are barely tolerated within the United Arab Emirates, of which Dubai is a part. When I visited Dubai two years ago to investigate the environmental and social impacts of its tourism industry for a book I was writing, no one was willing to talk to me on the record, such was their fear of speaking out against the ruling class. The few environmental groups that do exist in Dubai rarely stray from a brief that seems largely limited to educating school-children about the importance of recycling.

The one place where dissent does seem to be allowed - or is harder to police - is the internet, where people can hide behind their anonymity. Discussion forums are a popular way to vent criticism about the direction Dubai is taking, as are blogs such as Secret Dubai Diary. One recent controversy is that over Sammy the Shark, a young whale shark that was caught in the Arabian Gulf and then transferred to the aquarium at the Atlantis Hotel, which opened last month with a £20m party and firework display. More than 16,000 people joined a Facebook group calling for its release, and one local newspaper started a campaign urging that the shark be returned to the sea. A local radio DJ has even been playing a "Free Sammy" interpretation of Michael Jackson's Heal the World.

But while Dubai's citizens fight for Sammy to be freed, its leaders refuse to be diverted from realising their vision. At the United Nations climate talks, held in Poland earlier this month, Dr Rashid Ahmad Bin Fahad, the UAE's minister of environment and water, gave a speech in which he spoke of the need for his country to consider using nuclear power to desalinate its fresh water. Well, how else are they going to keep those swimming pools filled and chilled?

Cleaning up the Citarum River in West Java

Trying to Stop Pollution From Killing a Lifeline
Peter Gelling, New York Times 13 Dec 08;

BEKASI, Indonesia — The Citarum River, which winds its way through West Java past terraced rice paddies and teeming cities, is an assault on the senses. Visitors can smell the river before they see it.

Some fishermen still make their living off the river’s fouled waters, but many are no longer casting lures. Instead, they row their boats through floating garbage, foraging for old tires and other trash they can sell.

The river, considered by many environmentalists to be among the world’s most polluted, is woven tightly into the lives of the West Javanese.

It provides 80 percent of household water for Jakarta’s 14 million people, irrigates farms that supply 5 percent of Indonesia’s rice and is a source of water for more than 2,000 factories, which are responsible for a fifth of the country’s industrial output, according to the Asian Development Bank.

Villagers living along its banks use the Citarum’s dangerous waters to wash their clothes — and themselves.

Almost everyone sees the river as something of a movable dump: a convenient receptacle for factories’ chemical-laced effluent, farms’ pesticide-filled runoff, and human waste.

As a result, in stretches of the river near Jakarta, fish have been almost wiped out, destroying the livelihoods of thousands of fishermen.

“I know the color of the river is not right,” said Sutri, the owner of a small restaurant in Bekasi, an industrial suburb of Jakarta. “But I don’t know anything about dangerous chemicals. Anyway, there is nowhere else for me to get water.”

Sutri — who like many Indonesians uses only one name — said she washed the restaurant’s dishes in the river, along with her clothes and her children.

Environmentalists blame rapid, and unregulated, industrialization and urbanization over the past 20 years for the degradation of the 5,000-square-mile river basin.

The environmental damage is already costing lives; flooding, caused by deforestation and drains clogged with garbage, is a constant problem in cities along the Citarum.

The list of woes is worrying enough that the development bank committed this month to provide Indonesia with a $500 million, multiyear loan to finance a wide-ranging cleanup and rehabilitation plan devised by the bank and the government.

The money would be used clean the Citarum and the West Tarum Canal, which connects it to Jakarta, and to create a long-term plan for how to best use the river. A portion of the loan would go toward setting up an independent organization that would become the steward of the Citarum.

But even before the bank has begun to dole out the loan, it has opposition from local civic groups. They fear that the government is taking on too much debt and that there are inadequate protections to ensure that the poor see enough benefits and that the money is not lost to the corruption that is endemic in Indonesia.

“We are worried that the money could be lost through corruption,” said Nugraha, 30, a community activist who has been working to clean up this Jakarta suburb since he graduated from high school.

“And we are worried the farmers will be left out,” he continued. “The focus seems to be on the people of Jakarta, not the local people here.”

That the battle lines are being drawn so early, and despite the obvious need for change, is not surprising. “Water wars” in the United States and elsewhere can be nasty affairs.

Like most such battles, the fight over the Citarum will revolve around the complex issues of equity, economic development and environmental protection. Coming up with a plan that satisfies everyone’s needs will be difficult.

Raising community activists’ concerns, the first $50 million of the Asian Development Bank’s loan is designated for cleaning up the canal that brings the river’s waters to Jakarta, and for additional treatment plants. Because of health concerns, residents of the city rarely drink out of the tap, opting instead for bottled water.

Christopher Morris, a water resources engineer with the development bank, says it is committed to financing projects over 15 years that will benefit all the river’s users. Not all of the projects can be done quickly, he said.

“We are taking a long-term approach while recognizing there are some things we can fix quickly,” Mr. Morris said. “But changing the behavior of the community takes a lot of careful planning and preparation.”

Among the goals: building waste treatment plants to clean household water for the Greater Jakarta area, creating more dams so that additional water will be available for growing communities like Bandung, Indonesia’s fourth largest city, and simply cleaning the river so people living near it, including fishermen, can again depend on the source of water.

The plan calls for reforesting stretches of the river basin to help erosion and landslides that clog the river and regularly cause floods in Bandung, in Bekasi and elsewhere.

The tricky part of the work will be getting the many people who rely on the river for their living, or simply to live, to agree to changes. Conflicts can arise over the allocation of water between farmers who use it for irrigation and city dwellers. And trying to get farmers to use more efficient irrigation methods, so there is more water for others, can be challenging.

The solution proposed by the Asian Development Bank and the Indonesian government is a “water council,” with half the representatives from government agencies and half from the communities involved and nongovernmental organizations.

What authority the council would have remains to be seen; different levels of government already disagree about water allocation.

Of particular concern to community activists is how this council might be manipulated, becoming yet another avenue for corrupt practices.

Mr. Morris said the bank had not been blind to the opportunities for the money to be misused. That, he said, is why the bank decided to parcel the loan out over many years.

“The point is to make the money available to the government in an efficient way, so they aren’t sitting with a loan and paying charges on it until they actually need to use it,” he said. “But it also allows us to put in some safeguards and implement our anticorruption policies and other policies the Asian Development Bank promotes.”

With loan, a chance to clean up polluted Indonesian river
Peter Gelling, International Herald Tribune 12 Dec 08;

BEKASI, Indonesia: During the height of the dry season here, a once raging river and the canal that leads it to Jakarta, supplying the city with 80 percent of its water, carry a thick layer of sludge, a flotilla of solid waste that former fishermen now use to forage for potentially valuable trash in their wooden boats.

Some environmentalists call the Citarum the most polluted river in the world.

"There is no scale really to determine which is the worst," said Christopher Morris, a water resources engineer with the Asian Development Bank. "But it is very nasty. To say you can't swim in it, I mean, you know when you are a few kilometers from it."

The Citarum is a mighty river. Its basin stretches 13,000 square kilometers, or 5,000 square miles, across West Java, supporting a population of more than 28 million people and more than 20 percent of the country's industrial output.

Three hydroelectric dams produce 1,400 megawatts, and the river irrigates 400,000 hectares, or one million acres, of farms that supply 5 percent of the country's rice.

But rapid, and unregulated, industrialization and urbanization over the last 20 years have reduced the river to a national embarrassment.

More than 2,000 factories are now situated along its banks, everything from steel to oil to garments is produced using the river as both a source of water and a dumping ground for waste. The hundreds of smokestacks here in Bekasi, an industrial suburb of Jakarta, could be mistaken for a forest consumed by fire.

The 70-kilometer, or 43-mile, canal passes through Bekasi on its way to Jakarta, and along its banks another industry has formed - prostitution. Young women sit outside small houses, or cafés, offering sex to the thousands of nearby factory workers.

Along this stretch lives a woman in her 40s who runs a small restaurant.

The restaurant sits atop a high slope, at the bottom of which meanders the river. In the distance, the fog of industry swirls.

"I know the color of the river is not right," Sutri says, adding that she washes the restaurant's dishes in the river, along with her clothes and occasionally her family. "But I don't know anything about dangerous chemicals. Anyway, there is nowhere else for me to get water."

She will be one of the first to benefit from a $500 million loan from the Asian Development Bank that aims to jump-start a government program to clean up the entire Citarum River and the West Tarum Canal that connects it to Jakarta. In all, the Indonesian government expects the cleanup to cost $3.5 billion and take 15 years.

The loan from the Asian Development Bank, approved last week, will be delivered in several phases over those 15 years, with the first $50 million to go toward revitalizing the all-important canal, securing Jakarta's main source of water. The entire loan package will fund a myriad of sanitation and environmental projects as well as the building of waste treatment plants.

"We are taking a long-term approach while recognizing there are some things we can fix quickly," Morris said. "But changing the behavior of the community takes a lot of careful planning and preparation."

The plan, however, has critics. A coalition of community advocacy groups, collectively called the People's Alliance for Citarum, have raised concerns over the amount of debt the country is taking on for a cleanup plan that, they say, has few safeguards from corruption. Indonesia is widely considered to be one of the world's more corrupt countries.

Also, more than 800 people, mostly banana growers, who live along the canal might have to relocate. The alliance says there is no clear plan for their relocation or to reimburse them for the loss of their livelihood.

"We are worried that the money could be lost through corruption," said Nugraha, 30, who has been working to clean up the Bekasi environment since he graduated high school. "And we are worried the farmers will be left out. The focus seems to be on the people of Jakarta, not the local people here."

Nugraha's comment touches on another potentially difficult issue down the line: management of the Citarum River Basin, which spans several provinces. Questions remain about the allocation of clean water across the provinces.

The solution proposed by the Asian Development Bank is a "water council," half of which would represent government agencies and the other half civil society. What authority the council would have remains to be seen, as different levels of government disagree. Of particular concern to the alliance is how this water council might be manipulated, creating yet another avenue for corrupt practices.

The bank will, for the first time in Indonesia, introduce a multitranche financing system to address this very problem, Morris said, disbursing portions of the loan over time as needed.

"The point is to make the money available to the government in an efficient way, so they aren't sitting with a loan and paying charges on it until they actually need to use it," he said. "But it also allows us to put in some safeguards and implement our anti-corruption policies and other policies the Asian Development Bank promotes."
