Bangladesh gaining land, not losing: scientists

Shafiq Alam, Yahoo News 30 Jul 08;

New data shows that Bangladesh's landmass is increasing, contradicting forecasts that the South Asian nation will be under the waves by the end of the century, experts say.

Scientists from the Dhaka-based Center for Environment and Geographic Information Services (CEGIS) have studied 32 years of satellite images and say Bangladesh's landmass has increased by 20 square kilometres (eight square miles) annually.

Maminul Haque Sarker, head of the department at the government-owned centre that looks at boundary changes, told AFP sediment which travelled down the big Himalayan rivers -- the Ganges and the Brahmaputra -- had caused the landmass to increase.

The rivers, which meet in the centre of Bangladesh, carry more than a billion tonnes of sediment every year and most of it comes to rest on the southern coastline of the country in the Bay of Bengal where new territory is forming, he said in an interview on Tuesday.

The United Nations Intergovernmental Panel on Climate Change (IPCC) has predicted that impoverished Bangladesh, criss-crossed by a network of more than 200 rivers, will lose 17 percent of its land by 2050 because of rising sea levels due to global warming.

The Nobel Peace Prize-winning panel says 20 million Bangladeshis will become environmental refugees by 2050 and the country will lose some 30 percent of its food production.

Director of the US-based NASA Goddard Institute for Space Studies, professor James Hansen, paints an even grimmer picture, predicting the entire country could be under water by the end of the century.

But Sarker said that while rising sea levels and river erosion were both claiming land in Bangladesh, many climate experts had failed to take into account new land being formed from the river sediment.

"Satellite images dating back to 1973 and old maps earlier than that show some 1,000 square kilometres of land have risen from the sea," Sarker said.

"A rise in sea level will offset this and slow the gains made by new territories, but there will still be an increase in land. We think that in the next 50 years we may get another 1,000 square kilometres of land."

Mahfuzur Rahman, head of Bangladesh Water Development Board's Coastal Study and Survey Department, has also been analysing the buildup of land on the coast.

He told AFP findings by the IPCC and other climate change scientists were too general and did not explore the benefits of land accretion.

"For almost a decade we have heard experts saying Bangladesh will be under water, but so far our data has shown nothing like this," he said.

"Natural accretion has been going on here for hundreds of years along the estuaries and all our models show it will go on for decades or centuries into the future."

Dams built along the country's southern coast in the 1950s and 1960s had helped reclaim a lot of land and he believed with the use of new technology, Bangladesh could speed up the accretion process, he said.

"The land Bangladesh has lost so far has been caused by river erosion, which has always happened in this country. Natural accretion due to sedimentation and dams have more than compensated this loss," Rahman said.

Bangladesh, a country of 140 million people, has built a series of dykes to prevent flooding.

"If we build more dams using superior technology, we may be able to reclaim 4,000 to 5,000 square kilometres in the near future," Rahman said.

Birds fly north in climate change vanguard: study

Alister Doyle, Reuters 30 Jul 08;

OSLO (Reuters) - Birds have been moving north in Europe over the past 25 years because of climate change in the vanguard of likely huge shifts in the ranges of plants and animals, scientists said on Wednesday.

A study of 42 rare bird species in Britain showed that southern European bird species such as the Dartford warbler, Cirl bunting, little egret or Cetti's warbler had become more common in Britain from 1980-2004.

And species usually found in northern Europe, such as the fieldfare, redwing or Slavonian grebe, had become less frequent in Britain.

"The species are almost certainly responding to the changing climate," said Brian Huntley of Durham University in England of a report he wrote with researchers at Cambridge University and the Royal Society for the Protection of Birds.

The study tried to filter out other factors that would affect counts of rare birds, including growing public interest that could mean more sightings. Shifts in farming, pollution, expansion of cities and conservation efforts have all affected wildlife.

Birds and butterflies are among the first to adapt to climate change because they can fly long distances to seek a cooler habitat. Other creatures and plants can take far longer if their traditional range gets too warm.

"It depends on the mobility of the species. Birds and butterflies are two of the groups where there is the best evidence that species are already showing responses to the changing climate," Huntley told Reuters of the study in Royal Society journal Biology Letters.

GREENHOUSE GASES

The shifts in the birds' ranges since 1980 were also consistent with scientists' expectations because of global warming, blamed by the U.N. Climate Panel on human use of fossil fuels in power plants, factories and cars, he said.

The panel predicted last year that warming will bring desertification, floods, melt glaciers, raise world sea levels, bring big shifts in the ranges of species and extinctions.

"This gives us greater confidence in the climate models we use for other groups of species -- butterflies, plants, reptiles and amphibians," Huntley said.

"We rarely have the opportunity to test these kinds of models. We can only wait around for 50 years and wait to see if we were correct. It's better to have historic data" as a benchmark, he said.

Accidents in Singapore's port waters down 89.2% over last 10 years

Lynda Hong, Channel NewsAsia 30 Jul 08;

SINGAPORE : Despite more movements in Singapore's port waters, the number of piloted incidents dipped significantly over the past 10 years.

In 2007, there were only four such incidents, a decrease of 89.2 per cent from the 37 reported in 1998.

Between 1998 and 2007, the amount of movement in Singapore waters increased by 35 per cent - from 1998's 108,500 to 146,000 in 2007.

These figures were released by the Maritime and Port Authority of Singapore at its 6th Pilotage Incentive Award Ceremony.

Five pilots were commended for high safety and service standards at the awards ceremony.

Sam Goh Ek Kang, Hamzah Bin Ismail, Low Chong Lim, Jeremy Tan Hon Chai and Yap Kok Chua each received S$2,000 cash and a certificate of commendation. - CNA /ls

Biotech firm finds fortune in prawn farming

Bionovar diversified its business to prove the worth of its product; its revenue last year was $1m - more than its original biotech sales
Chua Hian Hou, Straits Times 30 Jul 08;

BIONOVAR started out as a biotechnology firm four years ago, but customers for its microscopic organisms, which aid in chemical-free prawn farming, were hard to come by.

So the local start-up took a daring step: It diversified its business to become a major customer of its own product - by going into the prawn-farming business itself. And it has not looked back since.

The initial problem in attracting customers? The market was saturated with competitors touting similar products to jaded and sceptical customers.

To counter this, the firm reasoned that getting into prawn farming would allow it to demonstrate the worth of these microscopic organisms - and thereby attract customers.

The microbes that Bionovar has developed help prawn farmers keep their facilities clean and disease-free in an environmentally friendly manner.

The 2004 foray worked out so well that Bionovar has made prawn farming a business mainstay.

It now runs a 50ha prawn farm in Malaysia producing 600 tonnes of tiger and Pacific white prawns every year. It has more prawn farms in India and will be expanding into China soon. It has also started a farm for tilapia fish in Vietnam.

Earlier this year, it set up a distribution arm to sell its prawns to gourmet restaurants and households in Singapore.

Getting to this point, though, has been challenging.

For one thing, raising money to get off the ground was incredibly difficult.

While many Singapore investors were 'curious' about Bionovar, few plonked down their cash, said chief executive officer Chia Boon Tat.

This was probably because Singapore investors have little experience with agriculture, he added. Even the company's biotech billing cut no ice.

'Investors wanted to hear 'biohealth', not 'bioagriculture',' he said wryly.

In the end, though, the company managed to raise $1 million to conduct research into microbes. This sum came from the three founders' own pockets, along with some from the brothers of one of them, and more from investors.

Since then, Bionovar has raised another $5.7 million for its prawn farms.

Its founders, who come from varying backgrounds, are Dr Chia, 46, a telecommunications executive; microbiologist Angelito Abaoag, 39; and aerospace engineer Liaw Kok Eng, 39. The trio, who met in 2003, got together 'by chance', said Dr Chia.

Back then, all three had been leading comfortable lives working for multinational companies.

'But we were also at that age when we wanted to go out and do something on our own,' said Dr Chia.

Rather than just talking about how to 'make the world greener', they decided to put their words into action.

The plan: use a combination of microbes - nature's own rubbish collectors - and beneficial bacteria or probiotics to help farmers reduce their reliance on pesticides and antibiotics.

The heavy use of chemicals in agriculture, said Dr Chia, has been increasing the level of pollution. Meanwhile, over-reliance on antibiotics has created new strains of diseases increasingly resistant to the drugs.

This, he added, was one reason that the region's aqua-farming, already a 'high-risk' industry, was going into a 'downward spiral'.

For instance, the typical prawn farmer finds it increasingly difficult to rear bigger - and more profitable - prawns.

Today, most prawn farmers harvest the prawns after 120 days. Dr Chia said keeping prawns alive after this period is very difficult because of the build-up of sludge in the pond.

The sludge, a combination of prawn faecal matter, uneaten prawn food that has begun to rot and plankton, eventually causes the pond's ecology to crash - and the prawns perish.

Bionovar uses microbes to break down the sludge, said Dr Chia. Compared to using chemicals as an alternative, microbes are a 'non-intrusive way to nurse the pond back to its original healthy state', he added.

He said that when Bionovar first tried to sell its microbes, it found itself up against many more well-established companies, all peddling similar products.

Customers were sceptical of the company's claims, having been burnt once too often by competitors' unfulfilled promises.

In the end, Bionovar managed to sell only some 'tens of thousands' of dollars of biotech products.

The resulting move into prawn farming has produced good returns. He said last year's profits from selling the prawns has already surpassed its original biotech sales.

Last year's revenue was $1 million. This year's revenue is expected to be several times that amount.

The company's profit margins are fattened by probiotics - dietary supplements containing beneficial bacteria like those used in drinks like Yakult. They help boost the prawns' health and survival chances. Bigger prawns mean wider profit margins, said Dr Chia.

For instance, Pacific white prawns harvested after the typical 120-day cycle usually weigh 10g to 12g and retail at about $10 per kg. By comparison, the same prawns harvested after 180 days weigh about 35g and retail at $24 per kg, he added.

Bionovar, which believes its success in prawn farming is due to its biotech origins, continues to maintain a research facility at Nanyang Polytechnic to continue improving its microbes.

However, it no longer offers its products for sale. Instead, it keeps them for its own use and thereby maintains its competitive edge over other prawn farmers, But it does offer a profit-sharing scheme for those interested in working with the company.

Its early forays into prawn farming were not always successful, Dr Chia said.

While Bionovar's prawn-farming process, on paper, was sound, there were a few instances when the entire population of its prawn ponds died due to 'human error', he said.

Today, though, its 50 staff at its prawn farms are more reliable and such heart-stopping moments are a thing of the past, said Dr Chia. Bionovar has 15 more employees in Singapore doing research and development, sales and other functions.

Dangers that lie ahead include disease and industrial espionage, he added.

Disease has led to tiger prawns, previously the dominant species among cultivated prawns, being largely wiped out and replaced by the more disease-resistant Pacific white prawns, said Dr Chia.

He believes it is only a matter of time before a similar outbreak hits Pacific white prawns.

The company has already started working on anti-viral products aimed at suppressing such outbreaks among prawns, as well as improving their resistance to diseases.

And as for competitors looking to steal its biotech, Bionovar has put in place countermeasures to prevent them from reverse-engineering its products.

Any attempts to reproduce the biotech in large quantities will result in products with 'significantly reduced capability and potency', said Dr Chia.

Green initiatives merely lip service?

Reader disappointed by government website
Today Online 30 Jul 08;

I REFER to “Sustainable if costs don’t tip the scales” (July 29).

Finally, the public can participate in the formulation of, and possibly even influence, policies surrounding the adoption of green living in Singapore.

I eagerly visited the site www.sustainablesingapore.gov.sg, but was dismayed at the small space provided for feedback. That says it all.

Either the Inter-Ministerial Committee on Sustainable Development is not expecting much feedback, or they are not expecting Singaporeans to think very deeply about this issue. I know of quite a few people who could probably write a thesis on the implementation of green living in Singapore and back it up with facts, figures, examples etc. How would such carefully thought through and well-researched opinions be submitted through this site?

I would also like to propose that such feedback be conducted via a forum platform, where the suggestions can be posted for all to see. Other members of the public can then also give their opinions on various suggestions. This format will allow the participants to exchange opinions and debate the merits of various suggestions, and in so doing, create a more vibrant and dynamic feedback process. It would also be a good step towards encouraging active citizen participation in issues that matter to them.

Public input for green plans
Straits Times 30 Jul 08;

HOW do you convince people to do the right thing? How do you change behaviour? Of course, there is the top-down approach, through legislation. But is it effective? The answer has to be, not always. For this reason, we welcome the approach the Government is taking in plans to build a more environmentally friendly Singapore: Find out from individuals, businesses and civic groups what they think, what they are passionate about and what their priorities are. Then, work with them. With such a 'buy-in', initiatives and plans will likely have greater support from the very start, as the public is involved in influencing the choice of programmes and of their design. In other words, the key is to determine the confluence between grassroots concerns and wants, and government intentions.

Towards this end, there will be opportunities through the Internet and forums for the public to share views and possible solutions to environmental challenges. For instance, feedback on home design for rubbish disposal and the habits might prove useful in designing ways that make it easier for households to recycle. And are there cycling groups out there, and what do they think it'll take to make the bike a commuting option? Enthusiastic public engagement with policy planners can lead to fresh ways of looking at old problems, and new insights from those closest to the issues, from consumers to small and big businesses and volunteer groups. The important thing is to get as many people involved as possible, so plans have the greatest resonance. This, however, is where difficulty might lie. Not all suggestions are workable, and they need to be sorted out without alienating people. This will take time and effort. Even before that, will the public respond in the number needed? While there is a good number of people who will relish the opportunity to have a say, there are also those who prefer to leave it to someone else. So getting people to become more involved will need some work.

It's one thing to seek responses to questions in a survey, and another to open up a dialogue with stakeholders. The former offers the possibility of crafting the best solution from a set of options. The latter, however, can offer solutions that hadn't even yet been considered. Whether it's energy conservation, recycling or reducing car use, changing entrenched habits isn't easy. But if the public is given a stake in how this might be reshaped, the bigger is the chance that it will stick.

Going green in Singapore
Business Times 30 Jul 08;

THE English economist, Thomas Malthus, famously if provocatively, asserted that world population growth would outrun food supply - and that this catastrophe would occur by the middle of the 19th century.

While his predictions fortunately didn't come to pass, the essence of his message did strike a chord - it still does today - and 'Malthusian' ideas and theories later proved highly influential in not only socioeconomics but even evolutionary science. Malthus laid bare the notion that human development, at the rate it was going even back in the 1800s, was unsustainable; mankind was living beyond its means.

Some 200 years on, the concept of sustainable development - now a rather loaded term that encompasses inter-related global issues such as environmental degradation, poverty and inequality - is a key UN priority, the subject of numerous global summits, and a policy initiative for many countries.

Singapore, as a near-mature First World economy in many respects, has now joined the global community in embracing the goal of sustainable development. It takes a straightforward approach: sustainable development for Singapore means 'being able to support future economic and population growth while maintaining a quality living environment that is clean, green and healthy', the government says. The motivations are both aspirational and plainly realist, driven as much by the Republic's vision to be an attractive, lively and liveable global city, as by the challenges of meeting growing resource demands amid severe constraints and rising fuel costs.

The committee of ministers leading the big drive has identified three main areas where 'green' initiatives will be focused - public transport, at the workplace, and where (or 'the way') Singaporeans 'live and play', which just about cover all bases. The ideas out of early feedback so far also hint at the costs and concerns involved in a subject that may still be a little foreign to most, both business and consumers. The Green Mark for property developers, for instance - which carries a cash grant of up to $3 million for green building and design features - has not seen widespread adoption. And already, the efforts to encourage greater use of public transport probably simply spells, for car owners here, ever-rising costs of driving, from ERP to parking charges.

Most interesting yet may well be the plans to promote cycling as a means of commuting, given the tweaks in road and footpath design - and pedestrian and driver attitudes - they entail. Indeed, the efforts on all fronts come down to, as the government notes, encouraging people and industries to adopt practices that are sustainable in the long term - a movement that calls for strong public education, and which, for the business sector, may well fail to gain ground in the face of more pressing priorities such as bottomline needs.

But both business and individuals must come around to the fact that going green in Singapore is no tree-hugging baloney; it is entirely in its own long-term best interests.

These creepy crawlies can help recycle food waste

Have no fear, for the worms are odourless and will not escape from the containers
Ong Dai Lin, Today Online 30 Jul 08;

NOW apartment-dwellers can go green in more ways than one — by recycling their food waste and generating compost for their high-rise gardens. The formula? A can of worms.

Since its debut at the Singapore Garden Festival on July 25, some 300 Singaporeans have already indicated interest in having their own worm farms.

While the worms are already being bred by GreenBack Private Limited in Kranji, those eager to start their own worm fertiliser farms in their balconies or backyards face a six-to-eight-week wait before taking delivery of their special worm housings — called Can-O-Worms — as these have to be shipped in from Australia.

Ms Nancy Chong, a retiree, is one of those keen on the product. Said the 60-year-old: “I do grow some plants in my flat, so I thought this is a very good idea and I wanted to know more about the product. My friends in Australia are already using the system and they do their own composting.”

GreenBack director Enoch Chia said the system was ideal for home use.

“Consumers just have to feed the worms with leftover vegetables and the worms will produce worm casts that can be used as organic fertilisers for plants,” he said. “We hope that Can-O-Worms can encourage people to recycle their own food waste and be more environmentally friendly.”

The worm farm is also supposed to be odourless as the food waste is quickly eaten up by the worms.

There is also little danger of the crawlies escaping from their containers, assured fellow GreenBack director David Murphy.

“The worms will not escape since they have food to eat in the trays,” he said.

“They may only escape if there is overpopulation but that is not likely as the worms will regulate their own population.”

Asked about after-care service for the worm farm, Mr Chia said: “We do not anticipate any problems with the product as the system is supposed to be self-maintaining. But customers can always call us if they have any problems.”

He added that this is a good time to bring in the product because of the green movement.

“There is now greater awareness to recycle waste and the government is also encouraging people to go green.”

Reflections on leading a Singapore social enterprise

Tan Suee Chieh, Business Times 30 Jul 08;

SOCIAL enterprises have existed for at least a century, but remain a relatively new concept to the man-in-the-street. Invariably, there will be some who confuse it with a charity, trade union or grassroots political organisation.

The key difference between a social enterprise and a commercial business is the social purpose of the former. This often revolves around providing essential goods and services for the masses, job creation for the socially disadvantaged or positive change in the environment.

While the distinction between the two is clear, the irony lost on many is that a social enterprise has to acquire many of the characteristics of a commercial business to thrive.

Throughout the world today, outstanding and successful social enterprises are run like any other commercial business, under sound and professional management practices, with a view to being sustainable for the long term.

There is a crucial difference between organisations with a social purpose and commercial businesses with a strong corporate social responsibility (CSR) programme. What basically separates the two is their core reason of existence, i.e. their purpose and philosophy.

Social enterprises put people at their heart of their decision making, with capital as an important and indispensable secondary. The reverse is true for businesses that count rewards for capital first - even for those with acclaimed achievements in CSR.

In other words, it is labour that hires capital at social enterprises, rather than a case of capital hiring labour for commercial enterprises.

Social enterprises trace their origin to philanthropic industrialists in the 19th century, who were called social entrepreneurs to acknowledge their genuine commitment to employees' welfare.

Over the years and over the world, technology, competition, globalisation, consolidation and heightened governance requirements have required social enterprises, especially those in the financial sector, to transform. Otherwise, they perish.

Notable examples such as Grameen Bank and British retailer John Lewis have stayed the course by adopting their respective industry best practices without compromising their social purpose.

The same cannot be said, however, for countless other ventures that floundered by downplaying the importance of sound management practices and capital management.

In his book Good to Great and the Social Sectors, Jim Collins used what he termed the Hedgehog Concept to explain how social enterprises could achieve the best long-term results. This is a model based on his research of the most successful social enterprises, premised on the notion that the best ones aligned themselves to what they were deeply passionate about, what they could be the best in the world at, and what drove their resource engine.

The latter comprises three basic components of time - how well the organisation can attract people, money, sustained cash flow, and brand, how well it can cultivate goodwill and support among its stakeholders.

These three attributes are reflected as three intersecting circles, whose point of intersection represents what social enterprises should ideally focus on.

The emphasis is not how much money the social enterprise can make, but how it can become sustainable to deliver superior performance relative to its social mission.

To succeed, Collins argues, social enterprises need to focus on their Hedgehog Concept. This would help them achieve superior results, which in turn would attract more resources and commitment they can use to build a stronger organisation. The latter would of course deliver even better results, creating the momentum for a self-perpetuating cycle of excellence.

The changes affecting many social enterprises around the world, as they transform and adapt to changing times, mirror those taking place at NTUC Income today.

As a homegrown social enterprise, we recognise the need to stay relevant and successful by modernising and professionalising the organisation, so that we can continue to attract both talent and customers. These measures include investing in professional systems and management tools for better decision-making, a more meritocratic career path for a more energised, motivated and professional workforce, and adopting more professional approaches and global best practices to strengthen our governance standards.

Our transformation is sometimes misunderstood as the commercialisation of NTUC Income and a betrayal of our social charter. The truth of the matter is that we remain ardently committed to place people, instead of capital, at the heart of our decision making. We just plan to do it more professionally, systematically and objectively.

Social enterprises that aspire to be truly great organisations need to have focus, discipline and the right processes in place.

But nothing can be more important than the values and purpose that guide them, and this will continue to be a key differentiating factor between social enterprises and their commercial counterparts.

The writer is the Chief Executive of NTUC Income

Indonesia's coal miner denies operating in forest areas

PlanetArk 30 Jul 08;

JAKARTA - Indonesian coal miner, PT Kaltim Prima Coal (KPC), has denied operating in protected forest, after an East Kalimantan regency ordered the firm to stop operating in some areas in a dispute over permits and land ownership.

East Kutai regency said on Saturday it had ordered KPC and another coal firm, PT Perkasa Inaka Kerta, to stop operating in these areas because the firms did not have permits from the forestry ministry for 40,000 hectares (98,840 acres) of land.

"Based on prevailing regulations, KPC's mining operation area is definitely not a forest area," the company said in a statement issued late on Monday.

KPC said that based on its contract of work, the authority to stop mining rested with the central government, represented by the mining and energy ministry.

"KPC has been conferred the status of a strategic national asset by the central government. Hence, KPC is requesting the central government to secure and protect the strategic national asset from any disruption. KPC is also examining its legal options in this endeavour."

The firm, a unit of PT Bumi Resources Indonesia's largest coal miner controlled by the family of chief social welfare minister Aburizal Bakrie, produced 38.9 million tonnes of coal in 2007, or about a fifth of Indonesia's total production.

Bumi Resources has said that its coal production at KPC was not affected by the order and was running normal.

India's Tata Power has 30 percent stake in KPC and another coal mining unit of Bumi, PT Arutmin Indonesia.

Perkasa Inaka Kerta is a unit of PT Bayan Resources Tbk, which aims to produce 9 million tonnes of coal this year and is set to raise US$529 million in an initial public offering.

A push towards greater regional autonomy since the end of the autocratic rule of former President Suharto in 1998 has often prompted companies to complain about having to deal with several sets of bureaucracy and double taxation.

It is often also not clear whether local decrees can be enforced or how they relate to contracts and central government regulations.

Indonesia is the world's largest thermal coal exporter and miners in the Southeast Asian country have gained from strong demand from China and India and record high coal prices.

Indonesia expects to produce 205 million tonnes of coal in 2008, with domestic demand seen at 52 million tonnes and the remainder to be exported, according to energy ministry data. (Reporting by Harry Suhartono, editing by Ed Davies and Lincoln Feast)

Building boom sapping Senegal's shoreline

Julie Vandal, Yahoo News 29 Jul 08;

It may be against the law, but every dawn along the beaches of Dakar dozens of men gather to steal a vital ingredient to sell on to Senegal's booming construction industry -- sand.

The "thieves" then trade the sand to building firms to use in construction projects, fuelling the development of Dakar's coastline while eroding its beaches.

"This coastal strip we are trying to protect has almost completely disappeared, said Amadou Balde, head of the Senegal SOS Coastline association. On the shore below, three men were filling up their wheelbarrow with spadefulls of sand from a sandbank battered by the waves.

One of these three pre-dawn workers was Mamadou. As the handcart filled with a mound of damp sand, he owned up to making four or five such illicit thefts each day, "sometimes more".

The theft of beach sand from any of this West African country's 700-kilometre (435-mile) coastline is, at least in theory, banned.

But in reality there is a booming black market for the sand, which has grown to meet the burgeoning needs of the Senegalese construction industry, currently on the upswing .

With a growth rate averaging 12.45 percent from 2004 to 2007, the building industry makes up 4.6 percent of Senegal's Gross Domestic Product. That makes the sector one of the most dynamic parts of the the economy in this west African state -- which otherwise is plagued by high unemployment where about half the population lives below the poverty line, according to International Monetary Fund estimates.

At the centre of the boom is the increasing spread of the Dakar urban area, where new housing is springing up like a rash. Piles of sand several metres high block every pavement.

"Everyone will tell you the opposite, but, with the exception of a few works of art, 100 percent of building sites use sea sand," confessed one entrepreneur, who did not want to give his name. "We don't have any choice, there isn't any other," he added.

There's just one problem: "it is contributing to the destruction of our coastline," according to Pape Goumba Lo, lecturer in applied geology at the University of Dakar.

There is only one place where sand-digging is officially permitted, a quarry 27 kilometres outside Dakar at Mbeubeuss, where sand-extraction has also intensified in recent years.

All day long huge yellow lorries, their skips full to the brim with sand, come and go from the site, heading for Dakar.

"Just imagine it. That's 400 lorries a day, each carrying 10 tonnes of sand, so around 7,000 square metres (8,372 square yards) of sea sand are disappearing each day," complained ecologist Haidar El Ali.

In order to step up the fight against illegal sand-extractors, the police have created a dedicated ecological brigade, which patrols the coastline along the Dakar suburbs several times a week. It was set up in May 2006.

In a four-wheel-drive vehicle in the middle of the night, warrant-officer Abdourhamane Diop and his team are on the lookout for sand thieves. Several handcarts and horses are visible along the seafront, but there's no one in sight.

"It's difficult to catch them in the act," bemoans Diop. "The word goes round that we are about, and they regroup after our patrol is over."

In the two years the squad has been operating, 84 people have been arrested, 99 handcarts have been seized, as well as 21 vehicles. On average, culprits receive a short jail sentence (one to two months) combined with a fine, which can vary from 100,000 CFA francs (150 euros, 235 dollars) to a million CFA francs (1,500 euros).

However, the deterrent effect of such punishment is limited, Diop said. "Even if we catch them, they start again because demand is so strong they can make lots of money, up to 80,000 CFA francs (120 euros) a month."

His feet deeply embedded in the cool sand of the Guediawaye beach, Balde is distraught at the future prospects.

"The whole world is complicit in this: from the thieves with the handcarts to those building the houses," he railed.

"When the sea is lapping at the doors of these new houses, what will they have to say for themselves?"

Eaten up: what happens when all food runs out?

Raj Patel's book Stuffed and Starved predicted the current global food crisis - spiralling food prices, starvation and obesity. Ed Pilkington meets the soothsayer of agro-economics and talks about what will happen when all the food finally runs out

Ed Pilkington, The Guardian 29 Jul 08;

There is a passage towards the end of Raj Patel's book, Stuffed and Starved, which elevates its author to the rank of soothsayer. He wrote it at the beginning of 2007, well before the roar of anger about rising food prices that resounded across the planet and that he so uncannily and accurately predicted.

The passage begins with Patel's summary of earlier sections of the book in which he depicts the wasteland, as he calls it, of the modern food system.

It is a system that destroys rural communities, poisons poor city dwellers, is inhumane to animals, demands unsustainable levels of use of fossil fuels and water, contributes to global warming, spreads disease and limits our sensuousness and compassion.

As if that litany wasn't enough, he then adds this: "Perhaps most ironic, although it is controlled by some of the most powerful people on the planet, the food system is inherently weak. It has systemic and structural vulnerabilities that lie close to the surface of our daily lives. All it takes to expose them is a gentle jolt."

When he wrote that passage, Patel had in mind his native Britain and its occasional history of food crises. There was the oil crisis of 1973 that prompted panic-buying in the shops. Or 2000, when protesting truckers blockaded the oil refineries and the shelves again came close to emptying. Those events inspired Patel to contemplate a startling question: "What would have happened," he wrote, "had all the food on the shelves run out?"

He left that question dangling in the book. But he got thinking about it again as he was on a tour of Australia last August promoting the book. As he travelled from Perth to Melbourne and then Sydney he kept being asked the same question: how did the drought that by then was already biting hard on Australian farmers as well as on consumers who were suffering rising prices, fit into his critique of modern food production? As he faced his audiences, it began to look to Patel, in a tentative, creeping way, that the gentle jolt he had written about was really happening.

"What was weird was that the stories I was hearing about drought and farmers in desperation were very similar to the stories that had been told to me in India a couple of years before. They were all about small independent farmers up to their eyeballs in debt. They had borrowed hugely to make a go of it, and then there'd been a shock - in Australia it was drought, in India it might be harvest failure, in Britain foot-and-mouth. It only takes one small shock."

And then the agricultural slurry really hit the fan. The first intimations of something truly out of the ordinary came in Mexico in early 2007, before he had finished writing Stuffed and Starved. There were reports of unrest in some of the larger cities about rising food prices, partly related to the decision of the US government to divert huge quantities of corn to ethanol production, in an attempt to reduce dependence on foreign oil. Then early this year some eight months after Patel had finished writing about the risk of gentle jolts - the so-called "silent tsunami" began. Food prices appeared to be out of control, spiralling up by 68% in the case of rice in the first four months of this year alone. Wheat and corn almost doubled in a year.

Such hikes on the costs of the basics of life hit the urban poor in the cities of the developing world hardest, and the misery was soon made manifest in the form of unrest. Impromptu protests grew into angry marches and then erupted into food riots. In Haiti six people died and the prime minister was ousted from power. Two days of rioting ensued in Egypt and 24 people died in Cameroon. The pattern repeated itself right across the developing world, from Guyana and Bolivia to Ivory Coast, Surinam and Senegal, Yemen, Uzbekistan, Bangladesh and South Korea. Wild events in turn prompted wild official responses. Vietnam introduced a night curfew on harvesting machines to stop illegal raiding of the fields; any Filipino caught hoarding rice was threatened with life in jail, Malaysia cancelled all public building works and switched instead to stockpiling food. Even the rich western world was hit. Food prices in the UK have risen almost 7% year on year, shaking the government's economic confidence. And if any doubts remained about the severity of this crisis, Wal-Mart, the supermarket goliath that stands at the pinnacle of the modern food system, announced it was imposing a four-bag limit for rice on its cash-and-carry customers to stop a run on supplies.

For millions of people around the world the soaring prices have spelt disaster - the World Bank has put the number of people who have been pushed into hunger at 100 million. But for one person, the impact has been strangely and paradoxically counter-factual. When Stuffed and Starved - Patel's first book - came out last August, he and his publishers imagined it would at best enjoy a specialist readership among globalisation activists attuned to issues of corporate greed and exploitation. But the food crisis has turned it from being a niche read into the literary equivalent of a crystal ball. As a result, the demand has in Patel's words "gone bonkers". Reprints have been ordered in Britain, the US and Spain, deals done for editions in Italy, China and South Korea and half a dozen translations are under discussion. "If I had been this popular at school I'd be a different man today," he quips. His analysis of the crisis, as the author of the book that predicted it all, is now hotly sought after. Or as Patel, who has the savvy Londoner's gift for self-deprecation, puts it: "Spank me, and call me Cassandra!"

We meet for lunch in a restaurant within a Big Mac's throw from Capitol Hill in Washington. It's trivial I know, but it's impossible not to be curious - a little intimidated even - about what Patel will order from the menu. He points out in his book that the livestock industry is responsible for 18% of greenhouse gas emissions, more than cars. So will he go for the hanger steak?

He asks for a pizza with goat's cheese and mushrooms, but when I ask whether his choice was politically or ethically motivated, he laughs. "I haven't had a steak in my life. Growing up in a Hindu household, I clamoured for hamburgers like any other kid and my parents said: 'Oh, if you must.' But they drew the line at steak."

Patel sees in himself, and his eating habits, a tale in microcosm of the globalisation he writes about. His family on his mother's side were civil servants in Kenya, and tin miners in Fiji on his father's side. They both were drawn to the mother country, arriving in London in the 60s, where they met. It later became a cliche, but they were among the first to open up "Mr Patel's corner shop", working 18-hour days in an era before 24-hour supermarkets. The earliest memories of their son, who was born in 1972, are of playing among the fags, mags and sweets in the shop in Golders Green. It would be too neat, I hazard, to suggest that his parents were forced to close down the shop because of competition with the supermarkets? "My dad did very well for himself," he replies, speaking with a high-velocity stammer. "But they were certainly driven out. You can't compete any more, the corner shop is a dying industry."

Despite those difficulties, the Patels did proud by their son, sending him to a north London grammar school, then to Oxford where he studied PPE, and finally to Berkeley in California. Along the way, he became interested in, and engaged with, the anti-globalisation movement. He was among the thousands who protested in Seattle against the World Trade Organisation (WTO) in 1999, and it was there that he came face to face with what he calls the "march of the farmers' movement" in the form of arguably the world's largest network of independent organisations, La Via Campesina, which represents around 150 million farm workers and smallholders across the globe. "I was struck by their sophisticated and detailed critique of the WTO. Seven years before Seattle they had already translated the draft text of the Dunkel report [on trade] into Kannada and were distributing it in the fields."

He began delving more deeply into the subject of trade, food policy and agricultural resistance as an analyst at Food First, a radical thinktank in Oakland, where an idea for a book emerged. It began life as a meditation on choice, or the lack of it - Coke v Pepsi, McDonald's v Wendy's. Its working title was Choice Cuts. Over the next three years he travelled to research the book from South Africa, Europe and South Korea to Brazil, Mexico and the US. In the process the thesis grew bigger in scope and more refined. Its focus was no longer just a lack of consumer choice, it embraced an entire world food system that can consign 800 million - more than one in 10 people on earth - to hunger while simultaneously inflicting obesity on an even greater number, 1 billion people. Hence the book's new, and in his opinion better, title.

His analysis shows how communities around the planet have been disempowered by a system that appears to offer an abundance of cheap food, but in reality dictates unhealthy and limited choices to an overworked and underpaid workforce that cannot afford any better. "The figure that often stuns people outside the US when I tour with the book is that 20% of American fast-food meals are eaten in cars. People are incredulous and ask: is that because Americans so love their cars? But living here you see how hard people work, for a pittance, with no healthcare, no decent education, not even a hint of a pension - so it's not surprising that the one hot meal you eat a day you eat off your lap. That's where the food system becomes a lifestyle."

Much of the broad argument in Stuffed and Starved will be familiar to those who have followed the debate on globalisation - how the liberalisation of trade has created a vast global market for heavily subsidised American and European agricultural products at the expense of local growers in the developing world; how relentless pressure to drive down food prices over 30 years has seen rich ecosystems replaced by monocultures that rely on oil-powered machines, chemical fertilisers and pesticides to drive up yields; and how international corporations and supermarkets that control the flow of technologies and of food itself have been the beneficiaries. It is a portrait of the agro-economics of the madhouse. "While we think our food is made for us, we are in fact being made for our food," he says.

Take India, which he describes as a storm of contradictions. "India has the most people in the Forbes top 10 billionaires list, but in the past decade the average calorie intake of the poorest has fallen. There are levels of hunger we haven't seen since the British left, combined with the world's highest levels of type 2 diabetes from the pressure of eating too much of the wrong kinds of food."

Or take the UK, where food producers are now less than one per cent of the workforce. The government may be committed to reducing global warming emissions, but meanwhile a quarter of all trucks on UK roads are carrying food and the average British family is driving 136 miles a year to buy it.

Or America. This is the country whose farmers, food giants and supermarkets benefit most from the global system. Such is the might of US food corporations that the double arches of McDonald's are more widely recognised as a symbol than the cross. Wal-Mart is the largest private employer not only in the US, but also in Mexico where Walmex takes in three out of every 10 pesos Mexicans spend on food. Yet amid such largesse 35 million Americans don't know where their next meal is coming from. "You are hearing these amazing stories of working American families adopting coping strategies that I learned about in development sociology - skipping meals, growing their own fruit and vegetables, giving up on meat. That's happening right here right now."

Which brings us back to the current food crisis. What surprised him, he says, is not that the food system felt a gentle jolt - after all, he predicted it - but that it has been pummelled all at once by a perfect storm of troubles. "We could have seen it coming because of the biofuels policy, which has always struck me as absurd, or the rising price of oil, or increased consumption of meat, or weird things happening with climate. But all these things happened at once, and that sent food prices through the roof."

And this time, there were none of the safeguards of grain stores, strategic food reserves, or import barriers that used to protect vulnerable economies from the vagaries of world markets. They had all been removed in the liberalisation craze of the past few decades.

His prognosis is that in the short term at least the crisis will carry on biting. Major institutions such as the World Bank persist, he says, in responding to events with the same failed policies of liberalisation of markets. "There's no reason why food prices should come down significantly. And if they don't, and there's no real impetus for governments to redistribute spending power, people will continue to take to the streets."

In the medium term, he's confident that change is in the air. He detects a growing seriousness and willingness to embrace new ideas in some unexpected quarters. The reason we are chatting in a DC restaurant is that Patel has just that morning been giving testimony before a Congressional committee investigating the World Bank's approach to food and development. With representatives from the World Bank, UN, Monsanto and other monoliths listening in, he told the committee that industrial agriculture could no longer be relied upon to feed the world and that we need a shift towards less fossil-fuel dependent farming and a return to rich ecosystems based on natural crop rotations and organic fertilisers. "Those are the kinds of things that are anathema to the World Bank and development analysts at the moment, and Congress normally doesn't want to hear them. That they called on someone like me is very weird, but very heartening."

In the longer term, though, even the current food crisis may seem mild. The world population is set to rise from about six billion today to nine billion by 2050. Global warming is likely to disrupt growing patterns and extend drought across Africa and the American south-west. Water resources for irrigation will be depleted. If we are already in a perfect storm, then we lack the terminology to describe what lies ahead.

I put it to him that any attempt to change world food production is like a game of poker with extraordinarily high stakes: it not only has to meet the massive yield of industrial farming - and say what you like about the modern food system, the one thing it has done is churn out mountains of the stuff relatively cheaply - it also has to raise it to support three billion extra hungry mouths. Can his alternative model achieve that?

"We've got an energy problem, a fuel problem, a water problem and global warming all coming at us," he replies. "Monoculture is heavily C02-emitting, water and fossil-fuel dependent. Clearly we can't carry on as we are. We can and we must meet this challenge with something new. So the question is what?"

That's not entirely an answer to my question. There is a slightly starry-eyed quality to Stuffed and Starved that is also striking about its author in the flesh. When he talks of alternative farming techniques that offer a way forward, the examples he chooses come from Cuba, Venezuela and a project in Oakland that follows in the footsteps of the Black Panthers. That's hardly going to play well with sceptical American policy-makers.

The other element that is lacking from his prognosis is any role for science and technological innovation in the search for solutions. Where technology does appear it is in the role of villain - GM crops are a ruse by Monsanto and others to secure corporate profits at the expense of the rural poor.

But isn't there a place for responsibly directed science in steering us through the coming maelstrom? Couldn't GM, for instance, prove to be crucial in developing drought-resistant crops as global warming tightens its grip?

"I'm big on science, married to a neuroscientist, I love it," he insists, protesting perhaps a little too much. "I like the way Cuban science approaches the problem. They say you can have GM crops if you can prove there's no better way of doing things. So they don't have GM crops, because there always is a better way."

Not exactly a ringing endorsement for the value of science. But then that is not where Patel's heart lies. For that you have to look to politics, and political resistance. The soothsayer's next book, he says, will be a look at the individuals and communities who are refusing to bow down to the current global system. He will soon be starting another journey to meet them. On his list: the slum-dwellers of Durban and the homeless Americans who run the University of the Poor. He sees in them a lesson for us all. "We are victims," he says as he polishes off his pizza and prepares to fly back to San Francisco where he now lives. "If we are choosing between Coke or Pepsi, Burger King or McDonald's, that's not choice. We should stop feeling guilty about that. We should start feeling angry".

Biofuels Major Driver of Food Price Rise - World Bank

Lesley Wroughton, PlanetArk 30 Jul 08

WASHINGTON - Large increases in biofuels production in the United States and Europe are the main reason behind the steep rise in global food prices, a top World Bank economist said in research published on Monday.

World Bank economist Don Mitchell concluded that biofuels and related low grain inventories, speculative activity, and food export bans pushed prices up by 70 percent to 75 percent.

The remaining price rise reflected a weaker US dollar, higher energy costs and related rises in fertilizer and transport costs, he wrote.

An unfinished version of the research that surfaced in news stories sparked a heated debate earlier in July, with trade groups for the ethanol industry calling the 75 percent figure "a stretch" and others saying it confirmed the dangers of current biofuels policies.

The findings by Mitchell, a widely respected agricultural economist, are controversial because they goes beyond most other estimates for the impact of biofuels on rising food prices.

Still, his findings correspond somewhat with the International Monetary Fund, which estimated in May that biofuels accounted for 70 percent of the increase in maize prices and 40 percent in soybean prices.

The Bush Administration, on the other hand, has estimated that biofuel production pushed food prices higher by 2 percent to 3 percent. Hoping to wean the country off foreign oil, Washington has boosted incentives and mandates for alternative fuels made from food crop.

Mitchell said without the increase in biofuels production, global wheat and maize stocks would not have declined, oilseed prices would not tripled and price increases due to other factors, such as drought, would have been more moderate.

Also, food export bans by countries trying to preserve food supplies and speculative activities would not have occurred because were in response to rising prices.

"The large increases in biofuels production in the US and EU were supported by subsidies, mandates and tariffs on imports," Mitchell said in the research, which looks at rapid rises in food prices since 2002. "Without these policies, biofuels production would have been lower and food commodity price increases would have been smaller."

Mitchell said biofuels policies that encourage subsidized production need to be rethought because they are hurting poor countries.

Bob Dineen, president of the Renewable Fuels Association, said the report showed a bias by the author against biofuels and underestimates the impact of higher energy prices and a weak dollar on higher food costs.

"Such a simplistic approach fails to accurately and honestly account for the myriad of factors driving food costs higher," Dineen said. "I encourage the author and the World Bank to revisit the issue without bias, taking into account the increasingly significant role biofuels are playing in reducing global oil demand."

Mitchell said the increase in grain consumption in developing countries was moderate and did not lead to the large price increases.

Growth in global grain consumption, excluding biofuels, was only 1.7 percent a year from 2000 to 2007, while yields grew by 1.3 percent and area grew by 0.4 percent, which would have kept global demand and supply roughly in balance, he said.

The use of maize for ethanol in the United States has global implications because the US produces about one-third of the world's maize and two-thirds of global exports; it used 25 percent of its production for ethanol in 2007/08.

Mitchell, however, said Brazil's sugar-based ethanol did not push food prices appreciably higher because Brazilian sugar cane output increased and sugar exports nearly tripled since 2000.

The increase in cane production has been large enough to allow sugar output to rise from 17.1 million tons in 2000 to 32.1 million tons in 2007 and exports to increase from 7.7 million tons to 20.6 million tons. (Editing by Leslie Adler)

Time to encourage biomass growth

David Williams, BBC Green Room 29 Jul 08;

Biomass energy is being touted as a key player in the push to green Europe's electricity supplies, says David Williams. In this week's Green Room, he argues that although there are promising signs, more needs to be done to encourage large-scale developments.

For some time, biomass has been seen as the emerging sibling of the renewable energy industry.

Despite much of the development behind the industry's technology worldwide, the UK's position at the front of the biomass revolution has been slipping.

Developers have naturally concentrated on cheaper forms of alternative energy, chiefly onshore wind, whilst other countries have stolen a march, with the Chinese particularly active by building hundreds of stations based on UK power plant models.

In recent months, however, we have seen something of a change in the UK, with a backlash against many more established alternative energy sources.

In the transport sector, biofuels have been attacked for their effect on food prices and actual carbon reductions, while wind has been criticised for its inability to produce a consistent stream of electricity and for its cost.

Many industry experts are now suggesting that biomass has to play the primary role in helping the EU to meet its challenging target of generating 20% of its energy from renewable sources by 2020.

Burning ambitions

Biomass works by converting (normally through burning) biodegradable matter such as wood, straw and agricultural wastes into heat or electricity.

Because it uses organic materials, any carbon dioxide released during the generation of energy is offset by that absorbed during the plant's life, so the process as a whole is broadly balanced, or "carbon neutral".

Crucially, it is an effective method of producing energy.

A single power station can produce around three times more energy as a windfarm for the same amount of generation capacity. It is also reliable and can be scaled up or down to meet consumer demand.

Of course, every technology has its drawbacks and there has been criticism of biomass because of its sourcing needs.

The requirements to power a single station can be extensive, particularly if it is using wood as its primary fuel source.

Some plants within the UK propose to import timber from as far away as Canada and Indonesia; this can potentially have a huge impact on the carbon footprint of the feedstock and the energy that it produces.

That's not to say that all biomass projects suffer from these issues. Some developers are now looking to generate energy by burning straw, which the UK has an abundant supply of and which, as a by-product of agricultural crops, does not have an impact on the food verses fuel debate currently engulfing the biofuel industry.

Supermarket giant Tesco has recently been given a green light to build Britain's first ever straw-powered Combined Heat and Power (CHP) plant to meet the electricity and heating needs of one of its distribution centres.

Utilising straw for biomass represents one of the most efficient methods for its disposal and pre-empts the need for it to be ploughed back into the land.

As a final, but vital, benefit, the UK can meet all of its requirements from domestic sources, cutting out the need to import supplies and allaying growing concerns over energy security.

Whereas heat for domestic-scale commercial installations could come from solar technologies or even heat pumps, it is widely acknowledged that the primary market can only be supplied by biomass.

After all, most heat comes from combustion of a fuel, and biomass is the only renewable and combustible fuel.

Red tape fears

So what next for the industry? More than £3.5bn ($7bn) was invested last year and this figure looks set to grow substantially, as green investment funds try to hedge against the credit crunch by diversifying their portfolio of renewables schemes.

Already a stream of projects are either coming online or expecting to do so shortly, including the world's largest plant near Port Talbot, South Wales.

Signs from government are also encouraging. Changes to its proposed Renewables Obligation Certificate (which offers incentives to suppliers to generate energy from renewable sources) will increase the value of energy generated by biomass in comparison with other sustainable technologies and make it more rewarding for investors to back.

In June, the Department for Business, Enterprise and Regulatory Reform (BERR) published its Renewable Energy Strategy that also made clear the important role that the industry could play, noting that there is a need to "develop a sustainable biomass market".

While this in itself is encouraging, there remains some concern over the detail.

The proposals mooted in the strategy have been primarily designed to make individual action more palatable, specifically a feed-in tariff to encourage microgeneration technologies in homes and a financial incentive mechanism to facilitate a general increase in use of renewable heat.

What they have not done, however, is to provide significant encouragement for commercial developers. There is a definite feeling by many in the industry that the current system is over-complicated and that applications are too frequently caught up in red tape.

By laying down a clear pathway that developers can follow, the government will be able to stimulate growth and at the same time provide the financial community with the confidence necessary for it to make the long-term substantial investments.

The result will be a step-change in the UK renewable sector as a whole, and the first step towards meeting the EU's 2020 targets.

Brazil defends biofuel's merits

Gary Duffy, BBC News 28 Jul 08;

At the busy Sao Manoel ethanol plant, three hours drive from the city of Sao Paulo, the noise from the churning machinery seems relentless.

Truckloads of sugar cane arrive from the nearby fields, some cut down by hand, some - in a sign of things to come - removed by machine.

From sugar cane fields to the garages of Brazil, doubts about biofuels in other parts of the world have not visibly slowed the process here.

Marcus Jank, president of the Sugar Cane Producers Association believes ethanol from sugar cane brings environmental and economic benefits.

"The first benefit is to reduce dependence on oil," he says.

"In our case we have replaced 50% of petrol with ethanol and also it was possible to have reduced the price of fossil fuels because of the competition with ethanol.

"We estimate that if there was not ethanol the petrol price would be 30% higher in Brazil."

Flex fuel vehicles

Ethanol's strength in Brazil has undoubtedly been helped by the development of flex fuel cars, which can run on any combination of ethanol or conventional petrol.



It is also widely available at petrol stations across the entire country and is generally the cheaper option.

The technology to make a car ready to run on flex fuel is neither complicated nor expensive - it costs just a few hundred dollars to adapt engines during the manufacturing process.

At the US automotive giant General Motors' (GM) plants in Brazil, there is no doubt that this is the future.

During the past three years, 100% of the cars rolling off the production lines here have been flex fuel, while across Brazil 90% of new cars are built the same way.

Future potential

The GM management in Brazil has enthusiastically embraced ethanol from sugar cane as an energy option.

And looking to the future, GM's president here, Jaime Ardila, says if governments and the private sector work together then emerging technology will offer answers to some of the concerns about bio fuels.

"The debate that has occurred on ethanol for good reasons - the concerns about food and food prices and so on - has clouded a much more important issue," he says.

"If governments and the private sector can jointly develop technologies to produce ethanol from sources that don't affect food and water consumption and so on and then help with distribution the world will definitely be better off."

Slave labour?

Undoubtedly, cutting sugar cane by hand in the fields is some of the toughest work imaginable, and working conditions in the industry have long been controversial. In some parts of the country it is sometimes described as akin to forced labour.



"In terms of slavery," says Braz Albertine, president of the Federation of Agricultural Workers in the State of Sao Paulo, "in Sao Paulo it is very difficult to say that here there is slavery work. In other states it has been found.

"We have already found worker' accommodation in terrible conditions, ethanol plants that delay payments or don't supply personal safety equipment.

"There are companies that work properly and others that don't."

The machines replacing the men who cut down sugar cane can already be seen in parts of the state of Sao Paulo and elsewhere.

Producers say this will help to address many concerns about working conditions.

At ethanol plants such as Sao Manoel, they say they keep within rules set by the government for rural workers, and have introduced changes to improve working practices.

Other fears have been raised by the Brazilian experience; some worry that the rapidly growing demand for ethanol will push crops and cattle further north, threatening the Amazon rainforest.

It is a concern that Marcus Jank of the sugar cane producers association is keen to reject.

"We are using 3.5 million hectares to produce sugar cane ethanol, and there are 200 million hectares of pastures in Brazil, so it is extremely small," he says.

"We believe that we are going to double the ethanol area in the next 20 years, but it will still be only 2% of arable land."

Greater access

If concerns about conditions are addressed, and land is well managed, says Professor Jose Goldemberg, of the University of Sao Paulo, ethanol from sugar cane has much to offer the developing world.

"In the next 10 years it offers a replacement of 10% of the gasoline (petrol) in the world, which is a large amount," he says.

"Today, about one trillion litres of gasoline are used in the world, and 10% of that could come from renewable fuel such as ethanol from Brazil and other tropical countries.

This, he claims would happen "without damaging food production, and without indirect effects such as damaging the Amazon forest and increasing deforestation".

To fully realise that potential Brazil and other developing countries will need greater access to world markets.

And that is exactly the kind of argument they have been putting forward as part of efforts to conclude the Doha trade talks in recent days.

Hurricane Dolly may have shrunk Gulf 'dead zone'

Janet McConnaughey, Associated Press Yahoo News 28 Jul 08;

The oxygen-starved "dead zone" that forms every summer in the Gulf of Mexico is a bit smaller than predicted this year because Hurricane Dolly stirred up the water, a scientist reported Monday.

There is too little oxygen to support sea life for about 8,000 square miles — just under the record of 8,006 square miles recorded in 2001, said Nancy Rabalais, head of the head of the Louisiana Universities Marine Consortium.

"If it were not for Hurricane Dolly, the size of the Dead Zone would have been substantially larger," she said in a news release sent from the consortium's research vessel, the Pelican, as she returned from her annual mapping cruise. Rabalais measures the area during the same period each year.

Scientists had predicted that flood runoff would bring so much fertilizer and other nutrients into the Gulf that the area of low oxygen would be a record 8,300 to 8,800 square miles. Those nutrients feed microscopic plants at the surface, which die and fall to the bottom. Their decomposition uses up the salty layer's oxygen.

Additionally, the fresh water from the Mississippi River and salt water in the gulf don't mix well and form layers, keeping oxygen from filtering through to the sea bottom. The oxygen-depleted, or hypoxic, waters can be deadly to fish, shrimp, crabs and clams.

The Mississippi River's nitrogen levels in May were 37 percent higher than last year and the highest since measurements began in 1970, Rabalais said.

Based on that, R. Eugene Turner of Louisiana State University predicted the oxygen-starved area would cover 8,800 square miles, and Donald Scavia of the University of Michigan estimated it would be 8,300 to 8,700 square miles.

But Dolly's winds and waves mixed up the layers of water, stirring in oxygen, especially along the western and shoreward areas, Rabalais said.

Another load of nutrients may be headed toward the dead zone as runoff from the mid-June floods in Iowa reach the Gulf of Mexico, said Steven F. DiMarco, an associate professor in the oceanography department at Texas A&M who also studies the dead zone.

"I expect that pulse to be making its way out in a few weeks. It could extend this year's hypoxic zone or dead zone further into the summer — maybe even in September," he said.

7-square-mile ice sheet breaks loose in Canada

Yahoo News 30 Jul 08;

A chunk of ice spreading across seven square miles has broken off a Canadian ice shelf in the Arctic, scientists said Tuesday.

Derek Mueller, a research at Trent University, was careful not to blame global warming, but said it the event was consistent with the theory that the current Arctic climate isn't rebuilding ice sheets.

"We're in a different climate now," he said. "It's not conducive to regrowing them. It's a one-way process."

Mueller said the sheet broke away last week from the Ward Hunt Ice Shelf off the north coast of Ellesmere Island in Canada's far north. He said a crack in the shelf was first spotted in 2002 and a survey this spring found a network of fissures.

The sheet is the biggest piece shed by one of Canada's six ice shelves since the Ayles shelf broke loose in 2005 from the coast of Ellesmere, about 500 miles from the North Pole.

Formed by accumulating snow and freezing meltwater, ice shelves are large platforms of thick, ancient sea ice that float on the ocean's surface. Ellesmere Island was once entirely ringed by a single enormous ice shelf that broke up in the early 1900s.

At 170 square miles and 130-feet thick, the Ward Hunt shelf is the largest of those remnants. Mueller said it has been steadily declining since the 1930s.

Gary Stern, co-leader of an international research program on sea ice, said it's the same story all around the Arctic.

Speaking from the Coast Guard icebreaker Amundsen in Canada's north, Stern said He hadn't seen any ice in weeks. Plans to set up an ice camp last February had to be abandoned when usually dependable ice didn't form for the second year in a row, he said.

"Nobody on the ship is surprised anymore," Stern said. "We've been trying to get the word out for the longest time now that things are happening fast and they're going to continue to happen fast."

Giant Chunks Break Off Canadian Ice Shelf
PlanetArk 30 Jul 08;

OTTAWA - Giant sheets of ice totaling almost eight square miles (20 square km) broke off an ice shelf in the Canadian Arctic last week and more could follow later this year, scientists said on Tuesday.

Temperatures in large parts of the Arctic have risen far faster than the global average in recent decades, a development that experts say is linked to global warming.

The ice broke away from the shelf on Ward Hunt Island, an small island just off giant Ellesmere Island in one of the northernmost parts of Canada.

It was the largest fracture of its kind since the nearby Ayles ice shelf -- which measured 25 square miles -- broke away in 2005.

Scientists had already identified deep cracks in the Ward Hunt shelf, which measures around 155 square miles. The shelf is one of five along Ellesmere Island in the northern Arctic.

"Because the break-off occurred between two large parallel cracks they're thinking more could go this summer before the freeze sets in," said Trudy Wohlleben of the Canadian Ice Service.

Asked to be more specific, she told Reuters: "More could be a piece as large as the Ayles ice shelf."

Ellesmere Island was once home to a single enormous ice shelf totaling around 3,500 square miles. All that is left of that shelf today are five much smaller shelves that together cover just under 400 square miles.

"The break-off is consistent with other changes we've seen in the area, such as the reduction in the amount of sea ice, the retreat of the glaciers and the break-up of other ice shelves," Wohlleben said.

She said a likely reason for the shelf breaking away was a strong wind from the south.

Warwick Vincent, director of the Centre for Northern Studies at Laval University in Quebec, said much of the remaining Ward Hunt ice shelf is now in a vulnerable state.

"It underscores the fact that each year we're now crossing new thresholds in environmental change in the High Arctic, and of course our concern in the longer term is that these may signal the onset of serious change at all latitudes, much further to the south, for example," he told Reuters.

Derek Mueller, an Arctic ice shelf specialist at Trent University in Ontario, said he was concerned by the rapidity of changes in the High Arctic over the last few years.

"It's a bit of a wake-up call for those people who aren't yet affected by climate change that there are places on earth that are, and the same could be true for them (these people) if you fast-forward a decade or two or three," he said.

Mueller initially estimated that 1.5 square miles of ice had broken off the shelf but increased that figure to eight square miles after studying the data more closely.

"Whatever has kept this ice shelf in balance for 3,000 years is no longer keeping it in balance," he told Reuters, saying he too would not be surprised to see more ice breaking away from the Ward Hunt shelf this year.

Wohlleben said the ice shelves, which contained unique ecosystems that had yet to be studied, would not be replaced because they took so long to form.

"Once they've broken off they're gone," she said. (Reporting by David Ljunggren; Editing by Peter Galloway)
