Safeguarding a very special place

April 27th, 2010

The Great Barrier Reef — the world`s largest coral reef and the only living thing on earth visible from space – is one of Australia`s great natural gifts. It is home to an abundance of marine life and known for its thousands of individual reef systems, coral cays and hundreds of tropical isles.

Reefs are important ecologically, economically and socially. In many parts of the developing tropical world, coastal communities depend primarily on them for food and protection from storm-generated waves. In Australia, the Great Barrier Reef (GBR) generates billions of dollars annually, mainly from tourism. “The whole nation is proud of it,” says Graeme Kelleher, who served for many years as chairman and chief executive officer of the Great Barrier Reef Marine Park Authority.

“Ecologically, the GBR protects most of the Queensland coast — more than 2,200 kilometres — from erosion and the destructive effects of storms,” Kelleher explains. “The biological diversity of the GBR is very high — more than 350 species of reef-building corals and more than 1,500 species of fish. It is regarded internationally as one of the best-protected reefs in the world, being enclosed in a World Heritage Area and the Great Barrier Reef Marine Park.”

“The Great Barrier Reef contains many outstanding examples of important and significant natural habitats for in situ conservation of species of conservation significance,” added Kelleher, who is also a former vice-chairman of the International Union for Conservation of Nature (IUCN) World Commission on Protected Areas. “It contains more than 2,900 individual reefs, covering more than 24,000 square kilometres, as well as about 980 islands.”

In the wake of the grounding of the Chinese coal-carrier Shen Neng 1 on the reef`s Douglas Shoal earlier this month, Australia announced that it would extend a satellite ship-tracking system to cover all of the massive reef, to reduce the risk such an incident occurring again. The system, currently in place for most of the GBR, would be extended south, Agence France-Presse said, and would force all ships to report their positions for tracking. The change must be ratified by the International Maritime Organisation, however, because much of the area is outside Australia`s territorial waters.

Until then, Australian transport minister Anthony Albanese said, safety agencies “will begin rolling out the infrastructure necessary to support the reporting system, such as sensors, communications equipment and modified navigational software. By beginning this work now, our authorities will be fully ready for the start of mandatory reporting in July 2011.”

In the Shen Neng 1 accident, oil spillage from the now-refloated ship`s tanks appears to be relatively minimal, with the greatest damage coming in the form of a three-kilometre-long scar gouged into the coral – and possible additional damage from the vessel`s paint.

The environmental scare, however, has heightened the urgency of efforts to ensure that ships can safely negotiate the Great Barrier Reef`s sensitive waters. “The key thing that we see is needed alongside this tracking system is to have pilots onboard every large ship that traverses the Great Barrier Reef World Heritage area,” the BBC quoted Richard Leck of WWF Australia as saying. Such professional navigators, he said, can prevent accidents. “Most of the incidents that occur within the World Heritage area are due to human error.”

Kelleher sees long-term benefit from the Chinese ship incident “in that without doubt, specific action will now be taken to ensure that large vessels in the future will be forced to navigate through the reef in even closer accordance with the very strict rules than is normal nowadays. It needs to be recognised that those rules are enforced strictly now.”

“This accident is without doubt a major navigational error,” Kelleher added. “A lateral error of 12 kilometres in navigation is really bad and unusual. I support the idea of large vessels carrying toxic cargo through the Great Barrier Reef being required by law to be guided by a specialised marine pilot in charge.”

The Great Barrier Reef scandal

April 27th, 2010

On 11 June 1770, six weeks or so after becoming the first European to make landfall on the east coast of Australia, Lieutenant James Cook unexpectedly ran aground. His ship, the Endeavour, had struck a reef now known as the Endeavour Reef, within a manifestly far bigger reef system, nearly 40 kilometres from shore. Only the urgent jettisoning of 50 tonnes of stores and equipment (including all but four of the ship`s guns), a delicate operation known as fothering (in which an old sail was drawn under the hull, effectively plugging the hole), Cook`s expert seamanship and a great deal of hard pumping saved the vessel and her crew.

It would be another 30-odd years before the great English explorer and cartographer Matthew Flinders, having circumnavigated the entirety of Terra Australis Incognita, the Unknown Southern Land, gave the vast reef system its name. But despite his astonishing success in charting a safe passage through its treacherous waters, mainly by the expedient of sending small boats ahead to sound the depths, Flinders himself was later stranded on it while heading home for England in 1803.

For nearly 250 years, the Great Barrier Reef has been a hazard to shipping. It is the world’s largest reef system, made up of more than 2,900 coral reefs and 900 islands scattered over 344,400 square kilometres off the coast of Queensland in north-east Australia. Covering an area bigger than the United Kingdom, it is also a priceless and unimaginably fragile world heritage site, home to 30 species of whales, dolphins and porpoises; six species of sea turtles; 125 species of shark, stingray and skate; 5,000 species of mollusc; nine species of seahorse; 215 species of birds; 17 species of sea snake; 2,195 known plant species and more than 1,500 species of fish.

And it is still a hazard to shipping. In recent years, its pristine waters, in theory protected by the statutes of the Great Barrier Reef Marine Park, have become known as the “coal highway”, a busy thoroughfare for foreign-owned bulk carriers bound for Asia. Laden with coal and fuel oil from Australia, thousands of ships — such as the Chinese-owned Shen Neng 1, which ran aground off the country`s eastern seaboard on April 3 — continue to jeopardise the largest marine conservation site in the world. As salvage teams worked to prevent disaster, environmentalists were not slow to accuse the government of turning a blind eye to the problem.

“This is the $60-billion-a-year, largely foreign-owned coal industry that is making a coal highway out of the Great Barrier Reef,” said Bob Brown, leader of the Australian Greens party. “There needs to be a radical overview of this huge coal-export industry, whether these ships need to use the reef at all, and what the alternatives are,” he said. Local fishermen have dubbed it the “reef rat run”, saying ships routinely take short cuts to save time and money on their voyage to China.

It was this so-called short cut, near the Douglas Shoal, off Rockhampton, that is believed to have caused the Shen Neng 1 accident. According to reports, the 230-metre-long ship, carrying 975 tonnes of heavy fuel oil and 65,000 tonnes of coal, was travelling at full speed when it hit a sandbank in a protected part of the Great Barrier Reef. Its fuel tank ruptured, causing a three-kilometre-long oil slick.

[After the vessel was refloated on April 12, the Great Barrier Reef Marine Park Authority`s senior scientist, David Wachenfeld, said the ship had gouged a channel about three kilometres long in the reef.]

The Queensland premier, Anna Bligh, has said the ship`s owner, Shenzhen Energy – which allegedly has been involved in three major international incidents in four years – could face a fine of up to one million Australian dollars (nearly US$930,000) for straying from a shipping lane that is currently used by some 6,000 cargo vessels each year.

The stricken ship was travelling to China from Gladstone, a port playing a growing role in the booming export trade of Australia`s natural resources to Asia. The incident follows a similar accident in March last year when 60 kilometres of Queensland`s south-east coast were declared a disaster area after 42 tonnes of oil spilled into the ocean from the MV Pacific Adventurer during a cyclone.

Conservationists say the fact that there is no legal requirement to have marine pilots on board ships in the area, to guide them safely through the 2,500-kilometre reef system, puts it in grave danger. “The current lack of safeguards around shipping in the Great Barrier Reef is akin to playing Russian roulette with one of the world`s most treasured natural icons,” says Gilly Llewellyn, the conservation director of WWF Australia, who called for ships to be piloted. She also wants improved monitoring systems so authorities know where large vessels are situated on the reef at all times.

The Australasian Marine Pilots Institute (AMPI), the organising body for Australia`s marine pilots, says the grounding of the Shen Neng 1 should focus attention on the lack of protection Australia`s maritime regulations afford the reef. An Australian maritime law expert, Peter Glover, says public opinion and government legislative reaction to marine pollution by commercial shipping in the Great Barrier Reef have got noticeably tougher since 1996, when the Panamanian-flagged vessel Peacock, en route from Singapore to New Zealand via the inner route of the Great Barrier Reef, ran aground on Piper Reef. The ship was carrying approximately 605 tonnes of bunker heavy fuel oil, and its owners were not even prosecuted.

Following the grounding of the 22,000-tonne Malaysian-flagged container vessel Bunga Teratai Satu on Sudbury Reef in 2001, legislative changes were introduced to allow both state and Commonwealth authorities to prosecute those who pollute in the waters surrounding the reef.

Those changes were put to the test almost immediately in the wake of another potentially catastrophic grounding the following year, of the Greek-flagged bulk carrier Doric Chariot. But Peter Glover believes it still “remains to be seen %26hellip; how effective legislative changes are in addressing the prosecution of individuals responsible for causing damage” in the reef.

Inspecting the scene from the air, Australia`s prime minister, Kevin Rudd, expressed concern that the Shen Neng 1, balancing precariously in the crystal-clear waters, had strayed so far from official shipping lanes. “From where I see it, it is outrageous that any vessel could find itself 12 kilometres off-course, it seems, in the Great Barrier Reef,” Rudd told reporters in tropical Queensland, where the reef park is a major tourist draw. He pledged an overhaul of measures to protect the Great Barrier Reef from any future environmental disasters. “There is no greater natural asset for Australia than the Great Barrier Reef,” he said.

But maritime traffic through the Great Barrier Reef is projected only to increase, with contracts reportedly signed for the export of US$60 billion worth of liquefied natural gas from coal seams as shrinking resources spur energy companies to turn to unconventional gas reserves to feed Asian demand. Work is under way to expand the port of Gladstone in Queensland to lift capacity by up to 25 million tonnes a year, driven by surging demand from Japan, South Korea, India and China.

Local fishermen fear any increase in traffic will put Australia`s most precious environmental asset at further risk. “We see ships through there every day,” Graham Scott, who has been fishing and chartering boats on the reef for 40 years, told the Sydney Morning Herald. “We see many, many boats within 15 miles [24 kilometres] of that spot [where the Shen Neng 1 grounded]. One or two boats a day, every time we`re out. We`ve assumed in the past that they`re not coal boats, because what would a coal boat be doing there?”

Briefing: habitat and biodiversity

April 17th, 2010

Biodiversity – or biological diversity – means the variety of life on earth, and is measured within species, between species and in the plenitude of ecosystems (the system of interactions between living organisms and their environment). In its biodiversity, China is one of the richest countries on earth. It is also one in which biodiversity has been most seriously damaged – and is still threatened.

With its huge population and long history of agriculture, China has been cultivating its vast territory for centuries. Forests and other types of vegetation were destroyed to clear land to cultivate more crops to feed more people. Wars and other chaos throughout China`s history have had their negative effects on the land and its life forms, and now climate change is playing a part. More recently, says China`s Biodiversity: A Country Study – labeled “a preliminary summary of China`s biodiversity and of the work needed for its preservation” — both the government and the public are more aware of the importance of biodiversity conservation. But threats to the country`s biodiversity legacy – one that is rich and varied, but also broken and incomplete — are still growing.

Forests, says the 1998 report — organised by China`s State Environmental Protection Administration (SEPA) and compiled with the support of the United Nations Environment Programme (UNEP) – have been “broken into small, fragmented areas”. Rangelands have been “overgrazed and severely degraded”. Animal and plant resources have been overexploited and overutilised. Atmospheric pollution, particularly in the form of acid rain, endangers plants, soil, lakes, fish and other resources. Invasive exotic weeds and animal pests have damaged indigenous life. Human activities, including tourism, mining and wetlands reclamation, produce a range of harmful effects.

As the report unequivocally states: “The survival of mankind cannot be separated from that of other species. Numerous plants, animals and micro-organisms provide indispensable human food, fiber, wood, medicine and industrial raw materials. %26hellip; The many beautiful and aesthetic life forms on the earth also give human beings much enjoyment. They are also sources of artistic creation and scientific invention. Most of the functions of living organisms cannot be replaced by other things. Today, man is modifying the features of the earth at an unprecedented rate. This creates raw materials for human survival on the one hand, but has changed the living environment of other living things, continuously decreasing biodiversity, and has led to the extinction of large numbers of species, on the other. The basis for human survival is gradually disintegrating and the protection of biodiversity is currently of worldwide concern.”

Experts, including the UNEP, consider China one of the earth`s 12 “mega-diverse” countries, ranking it third in the world for biodiversity in GEO-2000, the Global Environment Outlook, and first in the northern hemisphere. With more than 30,000 species of advanced plants and 6,347 kinds of vertebrates, representing 10 and 14 percent, respectively, of the world`s total (according to 1996 SEPA figures). Additionally, China is credited with 1,000 species of economic trees and more than 11,000 species of medicinal plants. Countless species are endemic to the country – ancient flora and fauna – and are both rare and endangered.

Washington-based Conservation International (CI), which works to protect the earth`s richest regions of plant and animal diversity, has identified 34 “biodiversity hotspots” globally. These are regions that contain at least 1,500 endemic species of vascular plants (greater than 0.5% of the world`s total) and which have lost at least 70% of their original habitat. Among the 34 hotspots on CI`s list are the mountains of southwest China, stretching over 262,400 square kilometers of temperate to alpine peaks between the easternmost edge of the Tibetan plateau and the central China plain. The mountains feed the most species-rich temperate and tropical river systems in Asia and “support a wide array of habitats, including the most endemic-rich temperate flora in the world.”

The region has evolved into “cluster of distinctive mini-hotspots,” each with its own unique flora and fauna, says CI, due to its dramatic differences in topography, climate and vegetation. The mountains are home to an estimated 12,000 species of plants, 237 of mammals, 611 of birds, and at least 90 each of reptiles, amphibians and freshwater fish – many of which are found nowhere else in the world. Two-hundred thirty rhododendron species – more than a quarter of the world`s total – are found there. So, too, is the richest variety of pheasants and their relatives – about 25 species – and, among mammals, there is the very symbol of China and of conservation: the giant panda. The animal, says CI, is “almost entirely restricted to the shrinking forests of this hotspot.” Other important mammals include the golden monkey, the Yunnan or black snub-nosed monkey, the takin (a large goat antelope), the Chinese forest musk deer and the snow leopard.

The World Conservation Union (also known as IUCN and based in Gland, Switzerland) is the world`s largest and most important conservation network. Among its functions is maintenance of the IUCN Red List of Threatened Species, a database recognised as the most authoritative guide to the status of biological diversity on the planet. It evaluates the extinction risk to thousands of species and subspecies. Its 2006 figures list 804 threatened species in China: 442 plants, 84 mammals, 88 birds, 34 reptiles, 91 amphibians, 59 fishes, 1 mollusc and 5 other invertebrates.

Deforestation – for agriculture, logging, dam construction, industry and human settlements – and climate change have played their part in the decline of China`s wildlife and habitats. So, too, has the destruction of grasslands and wetlands – such as the large freshwater swamps of the Sanjian plain in northeastern China. While habitats shrink, so too does the varied life of ecosystems.

And as Jared Diamond writes in his book Collapse: How Societies Choose to Fail or Survive, “Other biodiversity losses with big economic consequences include the severe degradation of both freshwater and coastal marine fisheries by overfishing and pollution, because fish consumption is rising with growing affluence. %26hellip; The white sturgeon has been pushed to brink of extinction, the formerly robust Bohai prawn harvest declined 90%, formerly abundant fish species like the yellow croaker and hairtail must now be imported, the annual take of wild fish in the Yangtze river has declined 75%, and that river had to be closed to fishing for the first time ever in 2003.”

As China pursues its aspirations to a “First World lifestyle,” the impact on human-resource use and the environment is certain to be immense.

Does biodiversity matter?

April 17th, 2010

Long since have I marvelled

How of ten thousand creatures there is not one

But has its tune; how, as each season takes its turn,

A hundred new birds sing, each weather wakes

A hundred insects from their sleep.

Ouyang Xiu (1007-1072) The Cicada

This poem by Ouyang Xiu conveys the essence of biodiversity, though it was written many centuries before the term was used in any language. Yet despite this early conceptual grasp of the earth`s immense variety, 21st century humans still struggle to come to terms with how and why biodiversity matters to us.

A broad definition – “the variety of living forms, their populations, and individual variations in appearance and behaviour” – presents difficulties to scientists asked to quantify biodiversity, who can only guess at the number of tropical rainforest insect species and the ecological roles that each may play. Our knowledge of the oceans and of seabed biology is in its infancy.

Which way China?

April 17th, 2010

China is a civilisation with a 5,000-year history of ever-growing inventiveness and refinement. From 600 until 1500 CE, it was the world`s most scientifically and technologically advanced society. It led the way in astronomy, mathematics, medicine, pottery and plant breeding. It invented the magnetic compass, gunpowder, cast iron, papermaking and printing. It alternated between being a closed, inward-looking society and a very open one that sought to link up with other civilisations.

China also built the largest and most spectacular cities before the modern era, with Beijing`s population reaching 2 million as long ago as the 17th century. However, it also continued to be a land of villages and farmers. Under Mao, this trend was strongly emphasised and China became a champion of village industries, collective farms and local self-sufficiency.

All that changed after Mao`s death. In 1978 Deng Xiaoping launched China on the “Open Door Policy”, focusing on rapid economic growth, a new role for markets, investment from the west and foreign trade. The world has watched in fascination and trepidation ever since, as pictures of vast factories and gleaming skyscrapers hit our television screens. Twenty-five years ago there was hardly any foreign investment, but by 2003 it amounted to US$680 billion. In a quarter of a century, China`s gross domestic product increased tenfold, from US$147 billion to over US$1.4 trillion. Its foreign trade grew more than forty-fold, from US$20.5 billion to US$850 billion.

But while China`s decision to industrialise and to urbanise has translated into a booming economy — with western-style consumerism spreading across the country — it has also generated major pollution problems. Sulphur and nitrogen oxides have turned China`s air into smog, and urban sewage, fertiliser run-off from farms and industrial chemicals are poisoning its rivers. There is also an increasingly global dimension: with one new coal-fired power station being built every week, and with China`s car production now nudging up to that of Japan, its CO2 emissions are catching up with those of the US. However, China seems to be learning the lessons of the limits to growth a lot more quickly.

When President Hu Jintao took over in 2003, searching questions began to be asked about the trajectory of China`s development. Since then a new policy emphasis on “harmony between humanity and nature” and on building “a conservation-oriented and environment-friendly society” has emerged. In recent speeches, Chinese leaders have insisted that “economic development must consider its impact on the environment and on society”.

There is growing evidence that these messages are increasingly informing the decisions of government officials and planners. One significant development is that the Shanghai Industrial Investment Corporation (SIIC) has commissioned the world`s first purpose-built eco-city — Dongtan. It will be built on Chongming island in the Yangtze River delta on an area three-quarters of the size of Manhattan island – 86 square kilometers. By 2010 it will be a city of 25,000 people; by 2030 the population will reach some 500,000. It is designed to be a beautiful and truly sustainable city with a minimal ecological footprint. The goal is to use Dongtan as a template for future urban design. As China is planning to build no less than 400 new cities in the next 20 years, Dongtan`s success is of crucial importance.

I have had the privilege to be working as a consultant on the Dongtan project with the global engineering and design consultancy Arup. The first phase of Dongtan Eco-City is conceived as a town consisting of three compact, pedestrian “villages”, each with its own distinct character. The city will then continue to grow as a collection of towns connected by cycle routes and public transport corridors, allowing inhabitants access to different parts of the city by tram, bus and bicycle, as well as on foot. The aim is to ensure that people will have to walk for no more than seven minutes from any part of the city to reach a bus or tram stop.

Dongtan`s design is based on the principle that all its citizens can be in close contact with green open spaces, lakes and canals. Its buildings will be highly energy-efficient, and the city will be largely powered by renewable energy — the wind, the sun and biomass.

Most of Dongtan`s waste output will be recycled and composted. The bulk of its organic wastes will be returned to the local farmland to help assure its long-term fertility and its capacity to produce much of the city`s food needs. Chongming`s existing local farming and fishing communities will have significant new marketing opportunities with the development of Dongtan, ensuring a high degree of local food self-sufficiency and enhancing the island`s long-term environmental and social sustainability at the same time.

Ironically, Dongtan is being built on an island in the Yangtze delta that is in itself a product of environmental catastrophe. In the last 50 years, Chongming island has become the world`s largest alluvial island, doubling in size, due to eroding soil from deforestation washing down in the headwaters of the river Yangtze. Chongming has grown from 600 square kilometers in 1950 to 1,290 square kilometers today.

One reason for the decision to create a new city of minimal environmental impact on Chongming island is the existence of a huge wetland area on the southern part of the island, which is a reserve for migrating birds and the largest of its kind in China. The wetlands will be preserved and will provide a strong visitor attraction. Vegetation from the wetland reserve will also permeate Dongtan, assuring that it becomes part of the island’s natural habitat rather than a barrier to it.

With Dongtan, a sustainable future is not some distant dream, but a vision that is actually being realised. The strategy for Dongtan Eco-City is for it to be developed in several stages in the next 30 to 40 years. A tunnel and bridge, linking Chongming island to Shanghai, are already under construction. In 2010 Shanghai will host the World Expo, and the completion of the first phase of Dongtan will demonstrate that environmental sustainability and access to nature are very much part of new development in China.

Dongtan is a local project with a global perspective, designed to ensure that China will play a key role in the emergence of a world of ecologically and economically sustainable human settlements. It is becoming clear that the planet will not be able to cope if 1.3 billion Chinese and 1.2 billion Indians behave in the same way as only a few hundred million people have done so far: extracting resources, consuming and polluting. As high-population countries such as China and India catch up with Europe, North America, Japan and Australia, worldwide sustainable development is the only way to go.

Dongtan is intended to set an example. It will be a pioneering eco-city that could become a blueprint for sustainable urban development, in China itself and elsewhere in the world. It holds a promise of a high-efficiency, small-footprint urban design. By 2010, Dongtan will be a compelling model for how to build sustainable cities worldwide that may well be too persuasive to ignore.

Trees are not enough

April 17th, 2010

Sustainable urban development in China depends on both the control of pollution and the protection of biodiversity. The importance of the former is now widely accepted, but the latter is still ignored, even by city planners. The wonders of Beijing`s culture are intimately linked with its biodiversity. Central Beijing has 226,000 old-growth trees, and there are 180,000 more in its suburbs. The city is surrounded by rich and diverse ecologies. Baihua Mountain and Wuling Mountain have 1,200 species of higher plants – a natural heritage more precious than any building. London, New York, Paris and Berlin do not have this kind of rich environment. Yet this natural heritage goes ignored.

The planting of trees on urban pavements has not taken ecological factors into consideration and is clearly artificial, monotonous and unreasonably spaced. In city centres, the large numbers of tall buildings and trees lining the streets prevent the flow of air, while in the suburbs more trees are needed. A sad sight, indeed, is the concreting over of the base of the trees, preventing the growth of bushes and grass. The needs of small mammals and birds are not considered. Poplars monopolise the streets of our northern cities – but where are the indigenous shrubs and plants? There is no canopy coverage and lifespan is short, with trees discarded within a couple of decades. There is no consideration of biodiversity.

Cities need to plan for long-term preservation – the older they are, the more valuable. When designing the imperial resort of Chengde, Emperor Kangxi ordered that all existing vegetation be retained. Tragically today`s city planners use only a few commercial varieties, and cities lose their native biodiversity. So some planners turn their eyes to surrounding villages and buy up large trees in great numbers. This means great business for the tree traders, but disaster for trees in rural areas. (In the worst case, rural trees literally fueled the steel-production drive of the Great Leap Forward.) The trend started in Shanghai and spread nationwide, and now almost every city beautification project ships in truckloads of large trees.

China’s trade in tiger bones

April 17th, 2010

Tiger bone wine (also known as “bone-restoring wine”) has recently appeared on the market in China. Does this mean that the 20-year ban on the trade in tiger bones has been lifted? This question has aroused great interest among animal protection activists in China and the rest of the world.

On August 25, China Youth Daily carried a report about tiger skeletons seen soaking in alcohol, and the resulting wine being sold, at the Xiongsen Distillery in Guangxi, southern China.

The Xiongsen Distillery is a subsidiary of Guilin`s Xiongsen Bear and Tiger Park, located in Pingnan county. It produces tiger bone wine and bear bile wine. The distillery has a storage capacity of 8,000 tonnes; it has already used over 400 skeletons from farmed tigers – and plans to expand. A company spokesperson confirmed that Xiongsen`s “bone-restoring wine” is indeed made with tiger bones.

Amazingly, the company`s sale of these products has been approved by the State Forestry Administration and Industrial and Commercial Bureau. But the wildlife conservation status that the two organisations have issued is written in English, and reads “lion”, rather than “tiger”. Perhaps this was meant to avoid international repercussions. After all, not many people in China would understand the English. Clearly, the company is aware of international sensitivity to the trade in tigers.

The plight of wild tigers is currently a great cause for concern. In July, a scientific survey found that tigers` habitats worldwide have been reduced by 40% over the last decade. China is home to only 50 wild tigers, any form of poaching or trade could quickly result in their extinction.

“Almost every war” is over natural resources

April 17th, 2010

Isabel Hilton: Professor Maathai, your story all began with one fig tree, a fig tree that you knew when you were a child. Could you tell me about that fig tree and what its significance was?

Wangari Maathai: When I was growing up in the highlands of Kenya, there were many fig trees, which were normally very huge, mysterious trees. They were nearly always green and had a huge canopy. But there was one particular tree that was very close to our household, and I must have collected some of the twigs that had fallen from this fig tree as I was collecting firewood for my mother, because I remember my mother telling me not to collect twigs from the fig tree. When I asked her why I should not, she advised that this was a tree of God. This tree is never cut; it is never burnt; it is never used for anything. Later on, I understood that when our people would offer burnt offerings they would do so at a fig tree. Fig trees were for all practical purposes a sacred tree, a revered tree. Not a God, but a tree that reminded my people of the mystery and the power, the greatness of the creator who was responsible for them and all the living things around them.

IH: But despite this, the fig tree that you knew, that straddled a stream that you played in, was cut down. What happened when the fig tree was cut down?

WM: This fig tree was cut down some 20 years later, when we introduced cash crops: tea, in this particular area. And because this fig tree was a huge tree, it was perceived to occupy a lot of land, and waste a lot of land where we could plant tea bushes to make money. So the farmer cut the tree and planted tea bushes.

When I visited the tree and found that it had been cut and saw where the [tea] bushes were, I was sad but also happy. Sad that the tree had been cut, but happy that nothing was growing where the fig tree used to stand. It was as if the ground refused to support anything else now that the fig tree was gone.

IH: What had happened to the stream?

WM: I came to understand much later that in fact these fig trees are very important in the ecosystem. They were part and parcel of a system that held the soil together, that prevented soil erosion and prevented landslides. And as I understood much later, the roots of this tree went deep into the belly of the earth, and reached the underground water reservoirs, which allowed the water to come up around these roots and to break where the land was weak. The land was weak right next to our house, where our stream broke. This was the stream that our house used, I used to go to this stream and fetch water for my mother. So when the tree was cut – amazingly – the stream disappeared. And this for me was the mystery that made the tree become significant to me. Especially later on when I understood the environment and understood how everything in the ecosystem is playing a role.

We may not understand it, but everything is playing a role. This fig tree was not only a habitat for birds and for animals. It was not only a beautiful tree providing shade, but it was also playing a role in the water system. And it was the reason this little stream was flowing, and my family could have clean drinking water.

IH: Looking back – what is the effect of your work on Kenya? Do you think that you have reversed this terrible environmental damage? You`ve certainly planted a lot of trees, but has this been enough?

WM: In areas where people have responded positively, especially among farming communities, the transformation of the landscape and the transformation of the people themselves has been revolutionary. To see ordinary people in charge of their environment; ordinary people concerned about their environment; ordinary people putting pressure on the government to protect, for example, forests. Forests are very important in our agricultural practices; we need rain, we need water, we need soil – and these are nourished by the rains that come from the forests. So it has been a wonderful experience to see these achievements.

Perhaps the next most important, besides the planting of the trees, has been the raising of awareness among ordinary people: the peasant farmers, the government officials, the policy-makers, not only in my country but within Africa – and now worldwide, to help in the collective raising of awareness. There are very many of us environmentalists, people working for human rights, people working for women`s rights and people working for environmental rights. And we have raised awareness to the point that the world is becoming more and more aware that the environment is very, very important. I think that maybe the culmination of this awareness was the awarding of the Nobel Peace Prize to the environment. To have linked the sustainable management of the environment with good governance, respect for human rights, respect for the rule of law and peace.

IH: What exactly is that connection, though? I think many people who think of the environment think of it as either a scientific matter or a matter of culture. But they don`t make a connection between the environment and politics or the environment and peace, what exactly is that connection?

WM: Many of us are educated – or persuaded – to think in boxes. So we think separately about peace, and we think we can work for peace. So we think separately about human rights, and we think we can work for human rights – or environmental rights.

But what the Norwegian Nobel committee was challenging us to do was to rethink this paradigm. To rethink this mental attitude we have about separating things, and think holistically. Think of many conflicts – conflicts within your area, far away from your area and far away from your country – and ask yourself: why are those people fighting? Almost every war is over access and control of resources. What the Norwegian Nobel committee was saying is that we cannot enjoy peace on this planet if we do not learn to manage our limited resources responsibly and accountably; and if we do not learn to share these resources more equitably. Quite often we think that those who have the power, those who have the guns and those who have the technology can access any resource at the expense of anybody. But sooner or later those who are marginalised and denied access to those resources will somehow seek justice – economic justice and social justice – and that`s how the conflict ensues.

That is the linkage we need to understand. And that`s the linkage we often don`t make, partly because when we go to school that`s not what we are taught. We need to rethink peace and security, we need to expand the definition to include sustainable management of our resources and their equitable distribution, and that will only happen if we govern ourselves in a way that we respect human rights, we respect the rule of law and we respect the diversity of our human species. Because we are very diverse, but wherever we are, whoever we are, whether we are many or few, whether we are dominant or subdued, we need to feel that we matter, that we are important in the society where we belong.

IH: Western environmentalists are often criticised in the developing world, on the grounds that the west and its model of development carried an environmental cost, but on the whole people became much more prosperous. And now large developing countries such as India and China are following the same path. So when western environmentalists complain about the environmental costs of that development, people in India and China say: but you did it, why shouldn`t we? What would you say to those criticisms? Are you one of those environmentalists who are trying to hold back the development of poor countries?

WM: Obviously it is a very difficult question. It`s very easy to say that the west pursued a very destructive development process at a time when many of the resources in the world were at their disposal, partly because they had the political power – many were colonial powers – and they also had made great advances in science and technology. They also were able to accumulate a lot of wealth both within and outside their countries.

But I want to go back to that challenge that the Norwegian Nobel Committee was giving to the world in the year 2004, which emphasised that we have limited resources. Because we have limited resources, and we have a planet that has limited capacity, are we going to literally hang ourselves to death? Are we going to destroy ourselves? Are we going to compete with each other to see who will kill this planet faster? I think that would not be very wise.

I know it is very difficult to tell upcoming economies: “don`t do it.” But what we are saying is: let us look at alternative paths to development. [Let`s not] prevent achieving a high quality of life, but there is a difference between high quality of life, and high consumption patterns. The pattern that the west has developed is an extremely wasteful, consumptive lifestyle that clearly needs to be changed. They have to accept the resources are limited. If they are going to over-consume, they are actually over-consuming at the expense of other people. So, it is not just China or India or other upcoming economies that need to rethink – it is everybody. And it is especially those who have already made much progress and those who have adopted a very consumptive pattern.

From another perspective, right now, we are looking at the reports that have just come from the Intergovernmental Panel on Climate Change (IPCC). They are saying that for the first time they are 90% certain that human activities are responsible for the warming up of the planet. These human activities include the burning of fossil fuels, the fossil fuels that are being engaged in the upcoming economies. If we are indeed at a point where our planet is threatened, do the Indians and the Chinese and other upcoming economies want to say: “let us sink together”? Are we going to follow the mistakes that were made by the western world? Or are we going to put pressure on the western world to cut down drastically on their emissions and to change their lifestyles, so that they can save themselves?

Africa is one of the areas that is going to be very adversely hit by climate change, yet Africa has contributed very little towards the problem. Are we saying Africa doesn`t matter? Are we saying other countries that haven`t reached that level of development don`t matter? I think that India, China, the US, Europe and all these highly-developed countries need to assume a moral responsibility towards the protection of the earth and life as we know it.

In 1977, Wangari Maathai founded the Green Belt movement, which has inspired many, often poor women in Africa to plant more than 30 million trees. In 2004 Professor Maathai became the first African woman to win the Nobel Peace Prize.

Poyang Lake: saving the finless porpoise

April 17th, 2010

This year I took part in a winter survey of Poyang Lake`s finless porpoises, organised by The Nature Conservancy’s Yangtze and Fresh Water Project. The study lasted for a week at the end of January, and was carried out by the Wuhan-based Institute of Hydrobiology of the Chinese Academy of Sciences. On Poyang Lake, I witnessed the shocking effects of large-scale sand dredging, which is threatening the survival of the finless porpoise.

It now seems possible that the finless porpoise, known in Chinese as the “river pig”, may go the same way as the baiji (the Yangtze River dolphin). In December 2006, a survey of the middle and lower reaches of the Yangtze River found no trace of the baiji, and the number of finless porpoises living in the Yangtze River is now also plummeting. Meanwhile, the Yangtze River basin`s ecosystem is suffering from the effects of shipping, sand dredging and over-fishing.

Urgent action is needed to save the finless porpoise, underlines Wang Ding, deputy director of the Institute of Hydrobiology. “There are between 700 and 900 finless porpoises in the Yangtze River itself, with about another 500 in Poyang and Dongting Lakes,” said Wang. “An optimistic estimate would put numbers at no more than 1,400 – less than half of the 1997 population. But although the porpoise population is currently dropping at a rate of 7.3% per year, it still has a hope of survival – if enough action is taken.”

Conserving China’s plant riches

April 17th, 2010

Scientists think there are around 320,000 different plant species on Earth – and China is home to around 10% of them. It is a treasure-house of biodiversity, yet it is growing and industrialising at breakneck speed. The pressure on China`s plant life is intense, as agriculture and industry demand ever more land. More than 5,000 plant species are used in traditional Chinese medicine, and an estimated 11,000 species possess some economic significance. They need millions of hectares and huge quantities of water. But so do the farms and the factories. And the export trade increases the fragility of China’s riches still further.

Wuhan Botanical Garden has been chosen to host the third Global Botanic Gardens Congress, organised by the Chinese Academy of Sciences, the Hubei provincial government, Wuhan municipal government and Botanic Gardens Conservation International (BGCI). It runs from 16 to 20 April, with 600-plus participants expected. The congress theme is appropriate: “Building a Sustainable Future: The Role of Botanic Gardens.”

The work of botanic gardens has never been more important. There are over 2,500 botanic gardens worldwide, with almost every country having at least one. The UK has over 100, but China can boast more than 140. Together, the world’s gardens cultivate around 100,000 species (almost a third of known plants) and are major centres of research and expertise for plant conservation.

The Wuhan Congress will be a rare opportunity for the world’s plant experts to meet, and to share their experiences, knowledge and research. One of the key topics will be how to use plants sustainably, despite the many and growing demands on them.

Sustainable use is now high on China’s agenda. Apart from domestic pressures, the global demand for its flora can have devastating results. The biggest-selling cancer drug in the world, Taxol, is made from several yew species. In fact, yews have also been used in traditional Chinese medicine for centuries to treat diabetes, although the whole tree except for the flesh of the fruit surrounding the seed is dangerously poisonous.

A single course of treatment with Taxol requires the bark of 7.5 average-sized yews. To produce a kilogram of the drug takes 3,000 trees, and current world demand estimated to be around 700 kilograms a year. With India, China is the biggest manufacturer and exporter of the raw material, so it is little wonder that 80% of the yew resources in southwest China`s Yunnan province were destroyed in just three years.

Taxol is only one of the gifts that China’s pharmacopeia offers the world. Other examples include the colon cancer treatment irinotecan, a standard chemotherapy that interferes with the growth of cancer cells, and topotecan, a chemotherapy used for ovarian and lung cancer. Both are modifications of Camptotheca acuminata, a native of China, where it is known as Xi Shu, or “Happy Tree”.

But this international trade is not a new thing. The first known account of the trade in agarwood, prized for use in incense, perfumery and medicine, was compiled by a Chinese customs official in 1200 AD. In 1998, over 1,000 tonnes of agarwood were traded around the world.

The demand now exceeds supply so much that several species are classified by the International Union for the Conservation of Nature (IUCN) as threatened. Agarwood is also listed on Appendix II of the UN Convention on International Trade in Endangered Species (CITES), meaning that trade must be controlled to avoid threatening the species` survival.

Around the world, in rich countries and poor ones, plants mean life. About 80% of people in the developing world depend on traditional plant-based medicines, and 75% of the top prescription drugs are derived in part from plants. They transform lives: Madagascar`s rosy periwinkle has improved the chances of surviving some forms of childhood leukaemia from 10% to 95% in the last 50 years.

Sustainable development is a priority for the United Nations Convention on Biological Diversity, the CBD, which works to conserve all the Earth`s species. It has developed a Global Strategy for Plant Conservation, agreed unanimously by all the 188 countries which have ratified the Convention. The congress will discuss how to reach this strategy’s list of 16 priorities for 2010. One way towards that is for individual countries to develop national strategies. The UK has done so, and after a meeting of British and Chinese experts in November 2006 – arranged by BGCI – China is close to being able to mark the congress by unveiling a strategy of its own at Wuhan.

The UK-China meeting was a pivotal point for plant conservation in China, bringing together a wide range of national and international partners. “Building on the excellent network we have established, we need to strengthen our collaboration in the future,” said Dr Jia Jiansheng, deputy director of the State Forestry Administration. “Continuing to work with CBD, BGCI and the UK Government, we join hands to conserve wild plants in China and overseas.”

But conserving a threatened species can be complicated. One Chinese plant, known to scientists as Cistanche deserticola and called suosuo dayun in China, provides a herb called roucongrong which is valued at home and abroad for treating impotence and infertility. It is in growing demand. But Cistanche will grow only as a parasite on another plant, Haloxylon, which is such good firewood that it is known as “coal in the desert”, and is also used for camel feed. So to save one plant, the conservationists have to work out how to rescue two.

Plants seldom attract as much attention from conservationists as some of the more obviously glamorous candidates for help. Campaigners routinely raise money in many countries to save the whale, the tiger and the panda, and many other of the “charismatic mega-fauna”: the big, iconic creatures now sliding towards oblivion.

Yet it is on plants that all life depends. Most terrestrial species either eat plants (if they are herbivores) or else eat prey which itself has fed on vegetation. Even zooplankton, the tiny animals which sustain almost all higher marine life, feed on plants – phytoplankton. Plants also produce the oxygen we breathe and absorb carbon dioxide, one of the main greenhouse gases.

But few people see a plant as any sort of icon. However, scientists believe that at least 60,000 plant species face some threat of extinction – and the total could be 100,000, between a quarter and one-third of the total number on Earth.

That is where BGCI, an independent, international organisation with its head office based at the UK`s Royal Botanic Garden at Kew, can help. It is the world`s largest plant conservation network, and its vision is a world in which plant diversity is valued and secure and supports all life.

And this year may see a historic breakthrough, both in China’s work to protect its own plants and in worldwide efforts to slow the inexorable slide of much of the plant kingdom towards extinction. It marks two anniversaries: the twentieth year since the establishment of BGCI, and the fiftieth birthday of Wuhan Botanical Garden, one of the crown jewels of China’s conservation work. Not only is the garden a stunning display case of many varieties of plants, but it is also a world-class scientific institute.

The problem is global, and much of the solution is likely to lie in China. The mountains of south-west China for example, are one of the world’s most diverse regions, with the greatest number of endemic plants (species found nowhere else) in the world. Of 12,000 plants found in the hotspot, 3,500 are endemic species. Among the most striking are the spring-flowering magnolias, half of which are known to be under threat of extinction in the wild.

China`s place in the fight to slow, arrest and hopefully reverse the loss of the world`s plants is pivotal. If it, facing the unparalleled challenges of very rapid modernisation and growth, can find the way towards the truly sustainable use of its unique flora, then every country can hope to do the same. It is a global test case: there are many governments waiting for China to give them a lead.
