Turtles, sharks most at risk in long-line fishing introduced in Sabah

Daily Express 1 Feb 09;

Kota Kinabalu: The long-line fishing method introduced recently in Sabah waters through licences to two local companies which will operate 10 boats is among the most depleting fishing methods and one which is non-sustainable, according to Sabah Anglers Association President Datuk Wilfred Lingham.

Leatherback turtles are most vulnerable to this method partly because the light sticks used to attract fish look like jelly fish - their favourite food.

Fish-eating Hawksbill turtles too are vulnerable.

He said long liners are estimated to kill in excess of 40,000 sea turtles, 300,000 sea birds (including the charismatic albatross), thousands of mammals and millions of sharks each year.

In view of this, he said the Fishery Department should rezone long line fishing limits from the 30 to at least 70 nautical miles.

On Saturday, Fisheries Director Datuk Rayner Stuel Galid said the licence conditions issued to the two firms require them to fish 30 nautical miles beyond the mainland.

"Thirty nautical miles is not very far these days and it will severely affect the livelihood of thousands of local coastal fishermen who depend on day-to-day catch," Lingham said.

"It means driving the last nail to the coffin because local fishermen who sink an average of two to three hooks a time can never match the catch of a longline boat which sinks between 2,000 and 4,000 hooks per boat.

"So we are talking about 10 highly mechanised boats each trailing a line potentially 20 miles long and branching with a possibility of 4,000 hooks per line - adding up to 40,000 hooks!" Lingham said.

"Furthermore, the boats may be Malaysian-owned but the operators are 100 per cent seasoned Vietnamese crew," asserted Lingham.

Lingham likened long liners to "vaccum cleaners of the seas which suck in all the live fish" where ever they operate, from bottom dwellers to pelagic, sea turtles and sharks.

"A lot of people think it is okay, let them fish, reasoning that this is just the commercial version of the traditional hook and line fishing. After all, the Vietnamese are just here to teach Malaysian fishermen how to use it!

"But make no mistake. All the facts and experiences elsewhere indicate long line fishing is indiscriminate and deadly," Lingham warned.

"Ocean vessels trail a main line up to 60 miles (about 100km) with secondary lines branching off that have thousands of baited barbed hooks," noted Lingham, quoting the US-based PEW Charitable Trust.

"A total of two billion such hooks are used each year, usually targeting large fish such as tuna, sword fish. But disturbing part is the baited hooks that attract a wide variety of other animals including sea turtles, marine animals, seabirds and non-target fish in what amounts to mass slaughter at sea," Lingham cautioned.

Sea turtles - a darling of Sabah's confident diving industry, are among the endangered victims of long lines because they are attracted to the bait used on longline hooks and die slowly from swallowing them.

They might also be severely injured by a hook in the mouth or by a hook that snags their flippers as they swim near the gears or they can drown if a large fish near them bite a hook and drags the line down so that they cannot surface for air.

"People may argue that the new circle hooks (also barbed) are less deadly but we are remain skeptical and critical," Lingham said.

"Take sharks, long lines are the worse culprit when it comes to shark finning, meaning just taking the fins and throwing the animal back to water, leaving them to bleed to death," he said.

"This (long line) fishing method is very effective in catching sharks because most sharks are surface dwellers and indeed many longline vessels are specifically targeting sharks. Shark fins can fetch a high price due to the demand in for Asian shark fin soup," he said.

"It's a cruel and wasteful practice yet still legal in many places and even though recently countries had started to adopt laws and international agreements against it struck," Lingham noted.

Sharks have no natural enemy except humans because they live at the top of the marine food chain which do their job with supreme efficiency as predators.

Their food range from planktons to crabs to sea urchins and clams.

Their scavenging role help keep the marine environment clean and maintain healthy marine populations because they eat up dead decomposing animals and a penchant in eating weak organisms.

To kill them with such wonton destruction with little brake at sight especially introducing long line fishing here is to lend a hand to destroy the delicate balance of the marine ecosystem as the population they prey on may multiply out of control.

Nobel laureates share experiences with Singapore students

Hoe Yeen Nie, Channel NewsAsia 31 Jan 09;

SINGAPORE: Big money has been poured into turning Singapore into a centre of scientific research and innovation.

But one Nobel laureate feels that time is what is needed to develop a home-grown pool of world-class scientists.

Professor Kurt Wuthrich, winner of 2002 Nobel Prize in Chemistry, said: "It is a relatively quick process to establish an environment of apparatus, of buildings, to run top-notch science.

"It is a very different aspect to educate young generations of scientists to make good use of the environments. That isn't done in two or three years. That typically takes two to three generations."

And a lot depends on how science is taught in schools.

Drawing from his experience in the United States, another Nobel laureate says students often miss out on the excitement of discovery and invention.

Professor Douglas Osheroff, winner of 1996 Nobel Prize in Physics, said: "It was not learning that I obtained in school, it was learning that I obtained from playing around in my basement.

"And sadly, I think students don't do that anymore. If they're going to play around with something, they're probably going to play around with computers."

The two scientists were in town to speak at a forum jointly organised by Hwa Chong Institution and the Nanyang Technological University.

Called the International Science Youth Forum, the event brings together well-known science researchers, teachers and students from all over Asia.

Hwa Chong Institution student Lim Lianjie said: "There was a lot of exchange of ideas, and it was really a platform to discuss with all the other international students as well. We actually learnt a lot during the whole dialogue session, and it was really interesting."

The forum was held in conjunction with Hwa Chong's 90th anniversary celebrations.

'Coastal' Punggol next big draw?

Residents looking forward to waterfront attractions & amenities
The New Paper 1 Feb 09;

IT LOOKS like a desolate wasteland now. On one side, the ground is dry and cracked; on the other is a small marsh covered in vines.
01 February 2009

IT LOOKS like a desolate wasteland now. On one side, the ground is dry and cracked; on the other is a small marsh covered in vines.

It's hard to imagine at the moment, but this site is set to transform into one of Singapore's premier waterfront estates in 2011.

Welcome to Punggol 21-plus, touted as one of the first public housing projects where residents can live close to water.

The major feature will be a 4.2km Punggol Waterway flowing through the eastern and western parts of Punggol.

It is slated to have water sports facilities, as well as scenic landscaping with alfresco dining.

With such attractive features, it's no wonder that the demand for flats in the area has exceeded the supply by more than three times.

High demand

According to the HDB website, 2,403 applications were submitted for 750 Punggol Arcadia units by the deadline last November.

Punggol Arcadia is one of four premium housing developments in Punggol launched last year under HDB's build-to-order (BTO) scheme.

While the mixed commercial and private residential units in the town centre are yet to be launched, demand is also likely to be high if the huge response to Punggol Arcadia is anything to go by.

Within Punggol itself, 23,000 HDB units are due for completion by the end of 2011, with another 21,000 units planned in the long term.

With these 44,000 units, the Government hopes to transform Punggol into a 'Waterfront Town'.

With construction scheduled to begin next month, nearby residents are excited.

Punggol resident and kiosk owner, Madam Hoon Yin Guat, 50, said she and her daughter are looking forward to jogging along the scenic paths.

'This sure beats walking along the ground floor of my block. My children will probably make use of the water sports facilities as well.

'The project timing is good. With many young families moving into the new homes in the area, I think they are more likely to take advantage of the new facilities,' she said.

Another Punggol resident, Ms B P Ho, 36, a clerk, said she would visit the new development since the area will have two LRT lines, with a total of 14 stations, with Punggol MRT station in between.

Only the Punggol East line is almost fully operational now, but when both LRT lines are running, passengers can alight at any of nine LRT stations situated within walking distance of the waterway.

Coastal attraction

Those living in nearby Sengkang are also keen to visit the Punggol Waterway once it's open.

Madam Gan Toh Chin, 56, a tutor, said: 'It's close to my place, so I don't mind going there since the scenery is expected to be nice. I hope there will be good food and entertainment.'

Another Sengkang resident, Mr Poon, who's in his 60s, checks out the site when he cycles in a wooded area there at least once a week.

Some even feel that Punggol may become the new coastal attraction.

Mr Chia Kok Yuen, 46, a taxi driver who lives in Jurong, said: 'With this project, there will be more places I can recommend to tourists rather than just the usual places of interest.

'I noticed that sometimes people from the east choose to go to West Coast, rather than East Coast because they find it crowded, so it may be the same with this new place.'

The Maldives and rising sea levels

The Maldives: Trouble in paradise
Rising seas are threatening to engulf the Maldives, so the president wants to buy a new homeland for his people. But should he instead be looking to build a new one on the grave of the old?
Christine Toomey, Times Online 1 Feb 09;

It is 1990 and a young writer sits in solitary confinement, his hands and feet shackled inside a metal tube, known as the “hot cell”. It is designed to heat up like an oven in the tropical sun. His food is deliberately laced with broken glass and laxatives, and he is repeatedly beaten — he has dared to openly criticise his country’s political elite. Through a slit in the metal walls he can see a sliver of ocean on the horizon. This is his only comfort. It is, he says, what opened his imagination, led him to think about a better future for his country.

Just a short distance from the small prison island where he is held, a paradise is being carefully crafted. The small knots of low-lying islands and coral-reef atolls that make up the Maldives are being engineered into one of the world’s most romantic tourist destinations.

Exclusive resorts are taking over many of the 1,200 tiny isles grouped in 26 coral atolls. Stilted luxury villas snake across translucent waters teeming with exotic marine life; glass floor panels have been installed underfoot in many. The trademark of these tourist oases is that no visitor’s request for pampering is considered too onerous. And the guest books will fill with the signatures of world-famous leaders and celebrities in the years to come. The daily grind for most Maldivians — prohibited from visiting these resorts to prevent what the government calls “cultural contamination” — was different. Little tourist revenue filtered down, and all dissent was brutally quashed. Those who criticised the country’s president, Maumoon Abdul Gayoom — who ruled his country with an iron fist from 1978, and became Asia’s longest-serving leader — were beaten and thrown in jail.

The number of inmates on prison islands like Dhoonidhoo, where the young writer was held, burgeoned. Corruption was rife, and drugs, with their related crime and violence, were allowed to flow into the country virtually unchecked.

Islanders in the more remote atolls still led the traditional life, living in single-storey homes built of coral fragments on streets made of sand with the sea never far away. Most survived from fishing and trading, taking advantage of the strategic position of their small nation, once a British protectorate, at an important shipping crossroads 400 miles off the southwest tip of Sri Lanka.

But as the population expanded, more and more people moved to the capital, Male, an island of less than a square mile, where overcrowding in low-quality apartment blocks became so acute that families were forced to sleep in shifts. Mountains of garbage accumulated in the streets and raw sewage was pumped into the sea.

In 1989, Gayoom’s government hosted the first-ever conference of small island states threatened by sea-level rises. The serious threat of global warming was only just coming onto the public radar, but Gayoom paid little attention. His priority was promoting tourist development. Now, 20 years later, Gayoom has gone, and a new menace threatens the Maldives. The battle for democracy has been won — but the battle against the force of nature is just beginning.

The young writer repeatedly tortured and imprisoned 20 years ago is strapped into the seat beside me as our plane lifts away from Male. His name is Mohamed Nasheed and he has only recently been elected president of the Maldives. Pointing out of the window at a seemingly uninhabited teardrop of green below, he shows me the prison island of Dhoonidhoo, where he was held the first of 13 times he was jailed for dissent. It is then that he begins talking about the effect his incarceration there had on his determination to “think big”.

“All you have to do when you are in prison is think, and even then I knew we were going to need dramatic solutions to the problems my country faces,” says Nasheed, a slightly built man of 41 with a high-pitched voice.

In 2004 the former dissident was granted political asylum in the UK, and it was here that he consolidated his opposition movement, finally overthrowing Gayoom in elections in October 2008. When we meet, the man his countrymen call “Anni” has had little time to introduce many changes. But one of his “big ideas” has grabbed global attention. Shortly after taking office, Nasheed made the dramatic announcement that he intends to start banking enough tourist pounds and dollars to buy a new safe homeland in which to relocate his 386,000 citizens when — not if — rising sea levels make the Maldives uninhabitable. Tracts of land in Australia, India and Sri Lanka are said to be under consideration for purchase. Nasheed’s plan caught the attention of the world’s media and led to a flurry of doomsday headlines painting a picture of a nation packing their bags and decamping en masse, waves lapping at their ankles. The truth, as always, is more complex.

According to the latest scientific estimates, sea levels are expected to rise worldwide by up to 60 centimetres by the end of this century as a result of climbing temperatures and shifting weather patterns associated with the build-up of carbon dioxide and other greenhouse gases. And this does not even take into account how much further sea levels could rise if the ice sheets of Greenland and west Antarctica start melting at ever more rapid rates.

But is it really feasible for an entire country to relocate itself to higher land? If so, how long would it be before it became necessary, and how do its people feel about such a prospect?

Nasheed leads me to his modest office at the back of the presidential complex. He refuses to use the opulent rooms Gayoom once occupied and plans to turn the sumptuous presidential palace into his country’s first university; one reason he thinks the Maldives has so many environmental problems is that Gayoom actively discouraged academic research and scientific inquiry among his countrymen, on the grounds that too much critical thinking could threaten his hold on power.

Nasheed explains that he has just received a visitor from Dubai. The businessman from the global investment company Dubai World — the company responsible for such futuristic land-reclamation projects in the United Arab Emirates as the Palm Islands and the World — had come to discuss the possibility of building underwater resorts for well-heeled tourists in the Maldives.

The president is reluctant to discuss the details. But one thing is clear: for those with money, whatever problems climate change brings will be regarded as little more than a financial challenge to be overcome with elaborate solutions. This is not the case for the majority of Maldivians. The country’s reputation as the richest nation in South Asia is misleading: its £3,100 GDP per head is unevenly spread; 42% of the population still live close to the poverty line.

“Every evil you think a society could have has found a home here in the Maldives,” Nasheed says. “We have inherited beautiful buildings from the previous regime, but almost empty coffers. There is an acute shortage of housing, sanitation, water, health, education, transport and basic infrastructures for a decent life.”

In addition, 30% of the country’s youth (and 75% of the population is below 35 years old) are now heroin addicts. Faced with such pressing social concerns, it seems surprising that Nasheed should give any thought to the long-term problems his country faces. “We’re in the front line of rising sea levels and we have to be prepared. I don’t want my grandchildren to end up as environmental refugees,” explains the president, who has two daughters aged 6 and 11.

The Maldives faced their first serious environmental wake-up call in 1998 when shifting ocean patterns associated with El NiƱo caused sea temperatures to rise to such a degree that normally vibrantly coloured tropical coral reefs around the globe suffered extensive bleaching, which causes the algae they feed on to migrate or die. Nowhere was this more dramatic than in the Maldives. Between 70% and 90% of all coral reefs surrounding the country’s 26 atolls are estimated to have died as a result. One diver swimming the length of reefs in North Male atoll at the time described it as an underwater equivalent of the snowcapped Alps.

Once the reefs died, coastal erosion escalated and the islands were left more exposed to the elements of nature than ever. Their vulnerability was graphically illustrated in December 2004, when the Maldives offered the tsunami of that Christmas scant resistance — it simply swept over them. With little of the damaging backwash that caused so much destruction in other Indian Ocean countries such as Indonesia, Sri Lanka, India and Thailand, the death toll in the Maldives — where 82 died and 15,000 were displaced — was low. But the tragedy led to a deep shift in the national psyche. The event was widely interpreted by the largely Sunni Muslim population as the act of an angry God. In the wake of the disaster, the proportion of women wearing religious head coverings in the country soared.

In an effort to win political favour – Nasheed’s opposition movement was by then gaining momentum – Gayoom went ahead with a rapid programme of artificial-harbour construction. More than three dozen additional harbours were built on the country’s 200 inhabited islands in less than three years.

Just as the destruction of coral reefs had a disastrous effect on the islands’ natural defences, so too did this construction programme, which drastically altered sea currents surrounding the affected islands, leading to more coastal erosion.

As I trail Nasheed and his environment minister, Mohamed Aslam, on a visit to one of the Maldives’ southernmost atolls and then travel to islands in the north to see such damage first-hand, the prospect of the Maldives one day disappearing beneath the waves becomes a lot more believable. It is already happening to part of Maduvvaree island in the northern Raa atoll, and the fear and disbelief are written on the face of the 45-year-old fisherman Abdullah Kamal.

Two years ago there were more than 50 metres of grass and sandy beach between the sea and the home where Kamal lives with his wife and eight children. Now the beach has vanished, the result of changing sea currents caused by a harbour built on the opposite side of the island. Some of Kamal’s neighbours’ houses have already collapsed into the sea.

“At night I lie awake and listen to the water lapping against the back wall of our house. The children cry. They’re very afraid, but we have nowhere else to go,” says Kamal. He has heard about the president’s plan to start saving money to buy a new homeland if the Maldives are one day inundated. But he does not believe his countrymen would want to move so far away. “We’re a nation of fishermen, and if they try to change that, our wings would be broken.”

Just how quickly sea levels will rise as a result of global warming is uncertain. But, as Aslam says, the effect of even a moderate rise in such a low-lying country as his will be quick and drastic. “If the predictions are right, in less than 50 years we could be in a really bad situation,” he says.

With only a 10-centimetre rise in sea levels Aslam paints a scenario in which coral reefs will begin to permanently lose their breakwater function. Not only will this lead to even more rapid coastal erosion, but the freshwater reserves that islands store in subterranean water tables will become saline and vegetation will die, leading to further soil erosion.

More than 100,000 people now live in Male, making it one of the most densely populated towns on Earth. The neighbouring island of Hulhumale, or New Male, has been designated to accommodate the overflow. A massive land-reclamation project to build an artificial island with an elevation of three metres is nearing completion. This project is cited by some as the way forward for constructing “contingency islands” to which the population could be moved when climate change makes the rest of the lower-lying islands uninhabitable.

The country’s influential environmental group Bluepeace proposes that seven such safe islands be developed in different areas of the archipelago to give Maldivians the chance of continuing to live there as sea levels rise.

“Most wouldn’t choose to leave and live thousands of miles from here,” says one of the group’s founders, Ali Rilwan. “We’re a very old civilisation. We wouldn’t want to be second- or third-class citizens somewhere else.”

Neither Nasheed nor Aslam rules out the construction of such safe islands, yet the president is in no mood for discussing such compromises. “People are either blissfully unaware of what climate change will bring, or are fed up with hearing about doomsday scenarios. So we must have imagination to make positive proposals.”

That is where Nasheed’s plan to establish a sovereign fund comes in. He believes it is essential that his countrymen also eventually have a “dry-land option”, a place where they can move within a bigger landmass. “It has to be there, as an anchor, to give confidence,” he says, as if talking about buying a simple insurance policy.

Of the $45m the government currently earns annually from tourism, Nasheed plans to start putting aside at least $2m a year into a fund, with contributions increasing substantially over time. This seems unlikely to be enough to buy a sizable chunk of land in the near future in such mooted destinations as Australia. But the government’s intention, he says, is that this fund be supplemented by donations from the richer nations that bear the brunt of responsibility for global warming.

Charity organisations are also calling for rich countries, such as the UK, to do more to help the developing world adapt to the effects of climate change, storms, famines and droughts. Oxfam, for instance, has called for at least $50 billion a year to be released from international carbon-trading programmes to help poor countries introduce adaptation schemes, such as upgraded early-warning systems for flooding.

When pressed, however, Nasheed says he only mentioned Australia as a possible destination out of solidarity with other small island states in the South Pacific such as Tuvalu and Kiribati, for which the rising oceans are also a ticking time bomb. Regional think-tanks are already urging the Australian government to draw up plans to relocate the small populations of these atoll states through staged migration as land becomes increasingly uninhabitable. A more realistic destination for Maldivians, says their president, would be a tract of land in one of the southern states in India, such as Kerala, where the relocation of 386,000 in a country with a population of 1.14 billion might be more feasible. “No country has said they will not have us,” says Nasheed. “We are going into unknown territory, so we have to have the vision to believe a new future is possible. If the Maldives is going to be underwater, for instance, who owns it? And if we move to another country, are we still a sovereign nation?”

While some may dismiss Nasheed as a dreamer, the questions he poses about his tiny island state will be multiplied by the vast areas of much more populous countries such as Bangladesh, China, Vietnam and Egypt that will also be inundated by rising sea levels. In Bangladesh alone, 17% of the country’s landmass is expected to be submerged in the next 40 years, making at least 20m homeless.

The spacious concrete-block houses lined up in the sand on the island of Dhuvaafaru in the northern Raa atoll have a very different feel from the traditional cramped dwellings of coral fragments on other remote islands in the Maldives. Little wonder, since these houses have only just been built by the International Red Cross and the Red Crescent to rehouse the entire population of the nearby island of Kandholhudhoo, whose houses were destroyed by the 2004 tsunami.

It is only two weeks since the 4,000 islanders moved into their new homes. For the past four years, most have been living in sweltering tents in scattered refugee camps on other islands. Here, at least, you might imagine that the population would be aware of the dangers future generations face from climate change. But there is little sign of it. “I do not believe that the climate will change and the sea will rise,” says Fauziyya Mahir, a 43-year-old mother of seven, as her fisherman husband sits in silence close by. “No matter what happens, I believe God will take care of us. I don’t think our new president should be talking about such things. We have enough other problems that need solving, like crime and drug addiction.”

Her view is typical, explains Dr Ahmed Razi, one of the community’s leaders. “It has taken scientists decades to accept that climate change is happening, so it is quite understandable that lay people don’t believe it. Fishermen are fatalistic by nature, and as a nation we are a religious people, so many people’s attitude will be to leave whatever will happen to fate.”

But fishermen in the capital, Male, say that they have already noticed significant changes in the local weather patterns. For more than 1,000 years a traditional calendar of sea-and-wind patterns known as the nakaiy existed in the Maldives, its frequent changes so reliable that its patterns were passed from father to son.

Ahmed Waheed shakes his head when talking of the nakaiy now. Resting in the shade of the cabin of his boat with his crew, the 53-year-old says the traditional period of calmer weather between December and April is now much more changeable, with higher winds and rougher seas. “But why should we be afraid of the sea level rising when our life is the sea?” he says, to which the rest of his crew nods.

“One of the biggest problems we face is a lack of understanding of how our islands are changing,” concedes Aslam, the country’s environment minister, who was recently held hostage for several hours by islanders in the south demanding he set a date for providing their community with a new harbour. He refused to bow to such pressure and eventually had to be set free by police.

As we sit talking, Aslam laughs off the incident, but sympathises with the frustration of his countrymen. “We welcome the international scientific community to come to the Maldives and use us as a laboratory for understanding the dynamics of our islands and the global implications of climate change,” he concludes.

When Nasheed joins us for supper, I am reminded of something that the young president said earlier: “The Maldives is the canary in the world’s carbon coal mine.”

Super Rice

Experts to tweak plant genes to boost yield by half and cut water and fertiliser needs
Alastair McIndoe, Straits Times 1 Feb 09;

Manila - Crop scientists call it supercharging the rice engine.

The International Rice Research Institute (IRRI) in the Philippines is launching a far-reaching project to boost rice yields by 50 per cent or more through genetic engineering to meet future demand for the staple food from rising populations.

It centres on re-engineering rice's photosynthesis - the means by which plants derive energy to grow - which the IRRI's scientists say has the potential to usher in nothing short of a new Green Revolution in Asia, the world's rice bowl.

A US$11 million (S$17 million) funding from the Bill and Melinda Gates Foundation has got the project rolling.

IRRI has formed a network of the world's experts on photosynthesis, including scientists from the universities of Oxford and Yale, for the task ahead. They are set to meet in April at IRRI's headquarters in Los Banos to draw up a research-and-development roadmap.

Last year's rocketing rice prices put the spotlight on whether Asia would be able to grow enough rice in the future because there are limitations to increasing production using current technologies.

Land for growing rice is getting scarcer across the region from creeping urbanisation and other uses. Simply put, Asia needs much more rice from less land.

The IRRI estimates that by 2050, rice production must rise by 50 per cent in Asia going by the region's current trend of population growth and rice output.

'We have a huge problem and superior photosynthesis is perhaps the only mechanism that can solve it,' said Dr John Sheehy, who heads the project at the IRRI.

Unlike rice, crops such as maize and sorghum have more effective systems of photosynthesis, enabling them to produce higher yields. These are called C4 plants, since they initially form a molecule with four carbon atoms during photosynthesis. Rice is classified as a C3 plant, with a less effective photosynthesis mechanism.

Scientists on the project aim to identify the C4 gene in maize and sorghum, and then construct genetic material from those plants that can be used to modify rice.

It will likely take at least a decade to produce a prototype rice plant, and another five years before C4 rice seeds reach farmers. On paper at least, C4 rice would not only significantly boost yields, but also need less water and nitrogen fertiliser.

'Considering that more than 90per cent of the world's rice is consumed within Asia and is the major staple for hundreds of millions of poor - and often undernourished - people, improving the efficiency of photosynthesis in rice would have an enormous impact,' said the IRRI's spokesman Duncan Macintosh.

What is more, added Dr Sheehy, 'the genes that we discover and construct for C4 rice can be put in other crops, such as wheat in Africa in dryland areas, helping to increase their production as well'.

The debate over genetically modified (GM) crops is as heated as ever, especially in Europe. Among the concerns is the ethical opposition to 'playing with nature'.

But the technology has been used to help crops better adapt to pests, disease and harsh environments. The biotech lobby also believes GM crops, such as pro-Vitamin A 'golden rice' that is being developed by the IRRI and others, can play a vital role in combating world hunger.

'I understand the concerns about some GM techniques, such as injecting an alien protein into rice; that would require caution,' said Dr Sheehy. 'But with the photosynthesis mechanism we don't need to do that. All we are doing is working to produce more carbohydrate and energy.

'C4 rice would be no more dangerous than mixing Rice Krispies and cornflakes in the same bowl.'

About 100 scientists from IRRI and universities and research institutions in Australia, Britain, Canada, Germany and the United States will work on the project.

The cost of producing a commercial variety of C4 rice is estimated at US$120 million.

'We're hoping for some early successes to encourage the Gates Foundation and national science councils in Asia to commit to larger amounts,' said Dr Sheehy.

North Sea sees recovery of cod stocks

Cod stocks in the North Sea are showing encouraging signs of a "rapid" recovery after being on the brink of extinction.

Jasper Copping, The Telegraph 31 Jan 09;

New figures from the International Council for the Exploration of the Sea (Ices) show that the number of adult fish in the North Sea is expected to increase by 42 per cent this year, the largest rise in almost 30 years.

Significantly, the quantity of fish capable of reproducing is this year expected to exceed 70,000 tons – the number set by scientists to mark the lowest level possible to ensure the species' long term survival.

It is the first time in a decade that the stock has risen above this milestone.

The recovery is likely to lead to further calls from British fishermen to increase the quota of cod they are permitted to catch.

The size of the spawning stock last year was just 49,941 tons. During the cod boom of the 1970s, the figure was more than 250,000 tons. It fell below 70,000 for the first time in 1999 and reached its lowest level, 28,921 tons, in 2006.

Various conservation methods have been introduced in an effort to help stocks recover, including changing the nets fishermen can use, a reduction in quotas, stricter enforcement by the authorities, restrictions in the number of days vessels can be at sea and the decommissioning of some boats.

Barrie Deas, chief executive of the National Federation of Fishermen's Organisations, said: "The stock seems to be rebounding very rapidly and it is very much good news.

"But no one can say which tactic has worked and what hasn't. Something obviously has, but it could just be mother nature."

He said the recovering population had led to increased problems with "discard" where fish are trawled up in nets and then dumped back in the sea because the fishermen have already reached the limits of their quota.

Representatives from the NFFO last week held a round of talks with ICES scientists, in Copenhagen, and with officials from the Department for Environment, Food and Rural Affairs (Defra), in London, about the recovering stocks.

The organisation is proposing greater use of "eliminator" nets, developed in the US, which catch haddock and whiting, while avoiding cod, as well as measures that would close off areas of the sea for short periods of time, when there are known to be large quantities of cod there.

In December, the quota for North Sea cod was increased by 30 per cent. Mr Deas said he hoped there would now be further rises.

Peter Hooley, from the Marine and Fisheries Agency, said: "We continue to monitor and enforce the rules for the purpose of conservation of fish stocks and 'real time' closures of fishing areas could be an exciting development. We are working with the industry."

Stuart Reeves, from the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the government's marine science agency, said: "Things are now crawling back up in the right direction.

"The 70,000 figure is the absolute lowest level we would like to see the stocks and the fact that we have been below it shows that things were pretty bad.

"We still want to see them much higher, but things are improving now. Some of the management has been effective. There is cause for guarded optimism."

The number of adult fish is calculated using catch data as well as scientific survey vessels.

Is recycling a waste of time?

For many households, 'Thou Shalt Recycle' has become the 11th Commandment. But some have claimed that we are worshipping a false idol.
Elizabeth Grice, The Telegraph 31 Jan 09;

The Thursday morning cacophony of rubbish collection in our north London road is as sweet as birdsong. In fact, it is the new dawn chorus. No one minds how long the rubbish lorry – or "stillage vehicle" – jams the cul-de-sac, or for how long, or how loud the din of breaking glass. There are never any complaints. This is because the weekly ritual of having the contents of our three recycling boxes sorted by hand and emptied into the vehicle's honeycomb of compartments reassures us once again that we have done the Right Thing. As the crews in their protective clothing swarm like flies over our waste, separating it as we watch, our whiffy labours of the night before are amply justified: we know we are helping to save the planet.

But a maggot of unease has crept into that satisfying thought lately. Are our plastic bottles really being recycled into more plastic bottles? Is the glassy detritus of the weekend's party – diligently sorted at the kerbside into green, brown and clear – becoming more glass bottles? Are our Bran Flakes boxes stuck in a council stockpile because China's recycling industry has collapsed? Are our potato peelings ending up in landfill, producing the evil greenhouse gas methane, instead of being safely digested?

An adviser on waste management suggested last week that it could be more damaging to the environment to ship material 3,000 miles away to be recycled, than to send it to an incinerator five miles down the road. But Wrap (Waste and Resources Action Programme), the Government's recycling quango, argues that sending used plastic bottles and paper to China – assuming that they are not then landfilled – produces less CO2 than sending them to landfill at home. Householders are confused. The 11th commandment, Thou Shalt Recycle, looks a shakier tenet than it did.

There is no question that, as an article of faith, recycling has taken hold. For two-thirds of households in Britain, it is now a way of life. In 2001, only 11 per cent of the nation's 10 million tons of municipal rubbish was recycled. Now it is 34 per cent. By 2020, the aim is 50 per cent. That is still behind Flanders (which is at 70 per cent) and Austria, the Netherlands and Germany (already at 50 per cent) but far ahead of Greece, where 90 per cent of waste goes to landfill.

Recycling saves energy, reduces raw material extraction and combats climate change. Everyone agrees on that. It takes 95 per cent less energy to make a recycled aluminium can than to make one from virgin materials. According to Friends of the Earth, recycling saves 10 to 15 million tonnes of CO2 a year – the equivalent of taking 3.5 million cars off Britain's roads. It is better for the environment than incinerators or landfills… and besides, we are running out of landfill sites.

But recycling has a complex hierarchy. In the London borough of Hackney, my recycling boxes are in relatively safe hands, because "kerbside sorting" makes for a better class of rubbish. Not all councils operate like this. Some use "commingled" recycling because it is cheaper. That way, householders put everything except food into one receptacle, which is trucked to an MRF (Materials Recovery Facility) where automated sorting separates recoverable items by size, weight and type. Although there is a huge environmental benefit to recycling glass – each ton re-melted in the UK saves 314kg of CO2 – last year, 280,000 tons of glass collected for recycling was only fit for aggregate because it had not been colour-separated.

When plastics, paper, aluminium and glass are kept separate, there is less chance of contamination. So they are worth more to the council and more to the environment. Alan Laing, a Hackney councillor, says this method offers the best chance of genuine recycling. "We have satisfied ourselves, as much as we can, that these materials aren't just going somewhere else in the world to be landfilled."

But they cannot really be sure, and it is no part of their remit to find out. Hackney gives its residents a neat map showing where their recyclables end up – oil to Cambridgeshire, foil to Walthamstow, tins and cans to Wales, kitchen waste to Edmonton. But beyond that, rubbish's onward journey can take it stupendous distances. Not least to China. A coloured plastic bottle sent to Greenwich might well end up 6,000 miles away in Taiwan.

That is not necessarily bad, say waste experts: this is a global market. We collect more paper than we can recycle, but there will continue to be a demand for it in China. Marcus Gover, of Wrap, says that despite the global economic slowdown, and a drop in prices for paper and plastics, the Chinese recycling market is stabilising. Reports of stockpiled raw materials are scaremongering, he suggests. "More than 95 per cent of our recycling is still getting through. There is no evidence of big stockpiles."

Although Britain lacks the infrastructure to deal with its rubbish mountain, there is room for optimism in the re-processing of plastics. Closed Loop London, a new £13 million plastics reprocessing plant in Dagenham, is turning 35,000 tons of used bottles back into food-grade plastic. When similar plants open in Derbyshire and Lincolnshire, they should handle most of Britain's 180,000 tons of plastic bottles a year without recourse to China.

"If we don't meet our targets," says Laing, "we will end up with more going to landfill and incineration. Councils pay £40 for every ton of rubbish sent to landfill. It is a cost time-bomb."

Separate food waste collections, say the experts, offer the biggest potential for making recycling more efficient. This is because food waste can be treated biologically – broken down by micro-organisms – and doesn't produce methane. In an impressive greener-than-thou initiative, Sainsbury is renouncing its old landfill habits. The supermarket's yearly landfill use, most of it ready meals, stale bread and rotten fruit, has been 80,000 tons: more than the weight of the Titanic. But by the summer, it aims to have stopped the practice altogether.

For the past five months, instead of sending lorries organic waste from its Northamptonshire distribution centre and 38 surrounding stores, it has been trucking it to an anaerobic digester operated by a small company called Biogen Greenfinch.

The digester is essentially a large steel stomach. It speeds up the breakdown of waste from years to days by feeding it into an oxygen-starved environment infested with microbes. The process generates a mixture of carbon dioxide and methane that is burnt for heat and power. What's left is sold as manure for local cereal farms – and the heat is piped to a nearby immigrant detention centre.

The supermarket plans to build five more "food-to-energy sites" in the next two years, shaving £2 million off its £9 million disposal bill – and hopes one day to sell surplus power to the grid.

Landfill sites, which release climate-change gases and pollute soil and water, still take most of Britain's waste. Increasing landfill prices, and the prospect of fines unless they reduce the amount of biodegradable waste they send there, has sent councils scrambling for alternatives, such as incineration.

Not that they call it incineration: too many overtones of smoking chimneys. Energy from Waste (EfW) is the preferred term. There are 17 EfWs in England and one in Wales dealing with household rubbish. Modern, well-managed EfW plants release fewer chemicals than old incinerators and are said to be less air-polluting – dioxin emissions have been reduced by 99.8 per cent since 1990 – but they are still environmentally inferior to recycling.

Friends of the Earth argue that however "clean" an incinerator, the most effective and sustainable way of diverting rubbish from landfill sites is to implement a good recycling and composting collection scheme.

Which brings us back to the householder and the kerbside. The battle for hearts and minds has to be fought daily to ensure there is no backsliding. That is why good practitioners will spend time reminding residents that their efforts are not futile. Letting the public know what happens to the materials when they have been collected reinforces the feel-good factor – but it also helps them keep the faith with recycling, at a time when it is being challenged as a middle-class con.

Far from it. Admittedly, recycling is not the easy fix we once thought it was: it won't "save the planet" and it is turning out to be a lot more complicated than we first thought. But doing nothing isn't an option and the long-term benefits are undeniable.

Whoever said keeping the faith was easy?

"Recycling is delivering great environmental benefits," says Wrap's chief executive, Dr Liz Goodwin, "and there is absolutely no reason for them to stop."
