Rainforest into cooking oil

Rainforest into cooking oil

Forests are disappearing because they are undervalued
The Economist – A special report on forests – Sep 23rd 2010

FROM a helicopter, East Kalimantan, a province in the Indonesian part of the island of Borneo, presents a dreary view. Where little over a decade ago rainforest transpired under a vaporous haze, the ground has been cleared, raked and gouged. Every few minutes, a black smudge, smattered with muddy puddles, denotes a coalmine. Angular plantations, 10km and more across, are studded with dark green oil palms. Tin roofs glitter on the shacks of loggers, miners and planters, each with a smallholding hacked out around it. Just a few straggly patches of forest remain, with greying logs scattered at their edges.

As often in Indonesia, commercial loggers in East Kalimantan have grossly exceeded their quota in a small fraction of their allotted time. Prematurely abandoned, the degraded forest then falls to illegal loggers or it is cleared for agriculture, often by fire. In dry spells, which are becoming more common, the flames get out of hand. In 1998 fires devastated more than 5m hectares of Indonesian forest.

Yet in the national accounts the clearance is recorded as progress. About a quarter of Indonesian output comes from forestry, agriculture and mining, all of which, in a country more than half-covered in trees, involve felling. But this is bad accounting. It captures very few of the multiple costs exacted by the clearance, which fall not so much on loggers and planters but on poor locals, all Indonesians and the world at large.

The Indonesian exchequer, for one, is missing out. Illegal logging is estimated to cost it $2 billion a year in lost revenues. But that can be fixed by policing. A bigger problem is that most of the goods and services the country’s forests provide are invisible to the bean-counters. Many of them are public goods: things like clean air and reliable rains that everyone wants and nobody is prepared to pay for. And where they are traded, they are often undervalued because their worth or scarcity is not fully appreciated.

Forest economics is plagued by these problems, partly because forests provide so many benefits. A UN-backed project in 2005, the Millennium Ecosystem Assessment, identified 24 main ecosystem services, most of which are found in forests: from preventing natural hazards, such as landslides, to providing the eco- in ecotourism. Yet most relate to forests’ role in the carbon and water cycles and in safeguarding biodiversity. And almost none is priced on markets. Forests are usually valued solely for their main commercial resource, timber, which is why they are so wantonly logged and cleared.

This leads to a profusion of damaging outcomes such as forest fires and lost ecotourism revenue that happen because those responsible are not obliged to pick up the tab. The inferno in 1998 is estimated to have cost over $5 billion in timber alone. According to another UN-backed effort, The Economics of Ecosystems and Biodiversity (TEEB), “negative externalities” from forest loss and degradation cost between $2 trillion and $4.5 trillion a year.

To tackle both problems, it may help to come up with a better evaluation of what forests are worth. That could open up new markets for their bounties through payment for ecosystem services (PES), in the jargon. Or the valuation alone may be sufficient to give pause to the axeman, or the taxman. TEEB’s experts are now putting price tags on forests and other natural boons, typically by calculating the opportunity cost of cutting them down and selling them off.

A draft TEEB report on the Amazon rainforest exemplifies its approach. It estimates the forest’s contribution to the livelihood of poor forest-dwellers, of whom there are at least 10m in Brazil alone, at between $500m and $1 billion a year. That is based on the estimated market value of the fish and thatch they take to subsist, and the gums, oils and other goods they harvest for cash. On a regional scale, TEEB estimates that the rainforest’s role in avoiding siltation in hydro-power reservoirs is worth anything from $60m to $600m a year.


A superior insurance policy
TEEB puts the rainforest’s contribution to South America’s agricultural output, through regulating the continental water cycle, at $1 billion-3 billion. That is based on a guesstimate of the drop in output that might result from even a small deforestation-related decline in precipitation. But Pavan Sukhdev, an economist with Deutsche Bank who heads TEEB, reckons the real figure might be ten times as much, given what Amazonian farmers seem willing to spend on insurance against rain failure.

As such wide-ranging numbers suggest, trying to price ecosystem services on such a big scale can be a mug’s game. The risks associated with ecosystem collapse are not well enough understood for any hope of precision. And whatever huge figure is arrived at will be notional, because no one can afford to pay it, which can invite feelings of helplessness. Yet the idea is that no one should need to pay it. And there is evidence that such valuations can indeed spur remedial action costing very much less. That was the effect of Lord Stern’s influential 2006 paper on the economics of climate change. And if the dream of international co-operation it elicited has generally faded, it still hangs, vaporously, over the forests. REDD, the nascent effort to persuade tropical countries to leave their forests be, is an effort at PES on a global scale. In forest economics, that is the Holy Grail.

At a lower level, bean-counters are becoming a bit less blind to nature’s bounty. For example, to mitigate inland flooding, Vietnam chose to spend $1.1m on planting some 12,000 hectares of mangrove forest, thereby saving $7.3m a year on dyke upkeep. To encourage such decisions, American scientists have developed an ingenious piece of software called Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST). In handy colour-coded maps it predicts the economic and environmental fallout of any proposed land-use change. This could revolutionise land-use planning. China is already using it to pick the best places for new protected areas on a quarter of its territory.

China has one of the world’s biggest PES schemes, a decade-old reforestation effort that has delivered 9m hectares of new forest. Launched in response to flooding of the Yangzi river, it involves paying farmers $450 a year per reforested hectare. Costa Rica is another PES trailblazer. Since 1997 it has made payments of $45-163 a hectare to encourage forest conservation, planting and agro-forestry. The money comes from a hydroelectric power company which is keen to protect its watershed; the World Bank, which reckons Costa Rica’s forest biodiversity is a global good; and a 15% surcharge on petrol. The country’s deforestation rate is now negligible.

Perhaps ominously for REDD, however, this scheme may have been less effective than many suppose. Costa Rica’s clearance was also reduced by better law enforcement and a shrinking national beef industry. Work by Rodrigo Arriagada of North Carolina State University and his colleagues suggests that the PES scheme was responsible for only 10% of the reduced deforestation on farms that took part.

 

The world is richer for them

The world is richer for them

 

As Costa Rica shows, there are many ways to raise PES money. In America and Australia, for example, markets have been established to help companies countervail the ecosystem destruction they cause, especially to wetlands. Through habitat banking, as this is known, a developer who drains a hectare of marshland can pay to restore a bigger area elsewhere. This is considered an apt form of PES for protecting biodiversity, the third great forest boon, because the services associated with it are especially hard to collect on. An obvious example is bioprospecting, the perusal of nature’s genetic library for new food, medicine and pesticide ingredients.

This alone should justify conserving forests, given how many useful discoveries they yield. Aspirin, derived from willow-bark, Taxol, a breast-cancer drug, derived from Pacific Yew bark, and an emerging class of cancer drugs known as mTOR inhibitors, derived from a molecule found in soil bacteria, are examples of ground-breaking medicines that originated in nature. “Plants, bacteria and fungi make a wealth of complex biologically active molecules that would be extremely difficult for us to match,” says Samuel Blackman, associate director of experimental medicine at Merck, a large pharmaceutical company. “We’re smart, but we’re not that smart.”


The price of ethics
But bioprospecting has done almost nothing to raise the value of standing forests. This is partly because of difficulties in attaching property rights to species. Most tropical countries find it hard enough to attach them to forests. And even if the ownership of biodiscoveries is established, charging for them is tricky. The value of new discoveries is uncertain, and they are swiftly synthesised. The value of old ones, like aspirin, is never paid retrospectively. “When you talk of biodiversity, it’s always about potential,” grumbles Aloísio Melo, of the Brazilian finance ministry. Potential can still be realised. But the strongest argument for protecting other species is often ethical. That helps swell the coffers of Western conservation NGOs, but it has few takers among tropical governments.

Still, understanding biodiversity can make it an important adjunct to conservation motivated by other concerns. For example, forests with high biodiversity will be more resilient to climate change. That is one reason why planting new forests—such as China’s vast stands of eucalyptus—though good, is not nearly as good as saving natural ones.

Seeing the wood – A special report on forests…

October 17, 2010 § Leave a comment

Purveyors of water, consumers of carbon, treasure-houses of species, the world’s forests are ecological miracles. They must not be allowed to vanish, says James Astill – The Economist – Sep 23rd 2010


DAYBREAK is a heavenly time to look on the Amazonian canopy. From a Brazilian research tower high above it, a fuzzy grey sylvan view emerges from the thinning gloom, vastly undulating, more granular than a cloud. It is mind-bendingly beautiful. Chirruping and squawking, a few early risers—collared puffbirds, chestnut-rumped woodcreepers and the tautologous curve-billed scythebill—open up for the planet’s biggest avian choir.

In a slick of molten gold, dawn breaks and the trees awaken. In every leaf, chlorophyll molecules are seizing the day for photosynthesis. Using sunlight to ship electrons, they split water molecules and combine the resulting hydrogen with carbon dioxide extracted from the air. This produces carbohydrates that the trees turn into sugars, to be burnt off in respiration or, by another chemical process, turned into new plant-matter. The main waste product, oxygen, they emit through their stomata in a watery belch. Hence the rainforest’s high level of humidity, visible from the observation tower in diaphanous cloudlets drifting over the canopy.

That plants emit oxygen has long been known—since 1774, in fact, when Joseph Priestley, a British chemist, found a mouse not too “inconvenienced” by being trapped inside a bell-jar with a mint plant. Yet the importance of plants’ ability to store carbon in making the planet habitable is still not widely appreciated. On two previous occasions when the atmosphere contained very high levels of carbon dioxide, the early Carboniferous and Cretaceous periods, beginning about 350m and 150m years ago respectively, they were reduced by the expansion of carbon-sequestering plants. Industrial burning of the fossil fuels laid down in the Carboniferous period, in the form of decaying plant-matter, is the main reason why there is now more carbon in the atmosphere than there has been for 4m years.

Carbon calculations

This is the latest reason—and it is a big one—why destroying forests is a bad idea. Roughly half the dry weight of a tree is made up of stored carbon, most of which is released when the tree rots or is burned. For at least the past 10,000 years man has been contributing to this process by hacking and burning forests to make way for agriculture. About half the Earth’s original forest area has been cleared. Until the 1960s, by one estimate, changes in land use, which mostly means deforestation, accounted for most historic man-made emissions. And its contribution to emissions is still large: say 15-17% of the total, more than the share of all the world’s ships, cars, trains and planes.

But this underestimates the damage done by the clearance. It also discounts a geological-time-honoured way to sequester carbon. That growing forests, natural or planted, do this is obvious. But there is increasing evidence to suggest that primary, or old-growth, forests are seizing the opportunity of a carbon-heavy atmosphere to suck up more carbon than they did previously, a process known as “carbon fertilisation”. By one estimate the Amazon rainforest is sequestering an additional 1.3 gigatonnes a year, roughly matching the recent annual emissions produced by clearing it. Across the world, forests and the soil beneath them absorb about a quarter of all carbon emissions.

This is an indispensable contribution to life as we know it, and forests offer many others, too. They house more than half the world’s species of animals, birds and insects. In the Amazon rainforest this biodiversity is staggering: even its small gullies and runnels often have unique sub-species of monkeys, birds, creatures of all kinds. Forests are also the source of most staple foods and many modern medicines. They provide livelihoods, wholly or partly, for about 400m of the world’s poorest people. They have always touched the imaginations of more privileged ones: “A culture is no better than its woods,” wrote W.H. Auden. Indeed, the more that people learn about forests, the more perilous their mismanagement seems.

They also make rain

That forests regulate water run-off, mitigating risks of flooding and drought, has been recognised since ancient times. The ancients also understood that trees can increase rainfall and deforestation can reduce it. Cutting down trees leads to a reduction in evapotranspiration, which results in less downwind precipitation. In the case of the Amazon rainforest this has huge implications for the agriculture of the whole of the Americas. That of southern Brazil, northern Argentina and Paraguay, in particular, depends for rainfall on the moist Atlantic trade winds, which cross the Amazon basin and then are deflected southwards by the Andes. There are also indications that the American Midwest is watered from the same source, by the moisture deflected northwards. The forest, by recycling the water that falls on it through evapotranspiration, plays an important part in this system.

Between a quarter and half of the water molecules that fall in the western Amazon have previously fallen on the rainforest. In its absence, it would be reasonable to expect a corresponding decrease in regional precipitation, which would be calamitous, but the actual effect could be much worse. Two Russian physicists, Victor Gorshkov and Anastassia Makarieva, claim that forests, not temperature, are the main drivers of winds. They base this on the previously unconsidered drop in pressure that occurs when water passes from gas to liquid state in condensation. So ecosystems that maintain a moist atmosphere—as rainforest does—draw in air and moisture from elsewhere. This could explain the curious fact that precipitation in the western Amazon is higher than it is upwind, despite leakage in run-off at every revolution of the local water cycle.

The theory caused a stir in Western academia last year when it was put forward in the journal Bioscience and is considered far-fetched by many. But it should reinforce the point that, on hydrological grounds alone, conserving forest is often essential.

And still they are being chopped down. According to the main compiler of forest data, the UN’s Food and Agriculture Organisation, about 4 billion hectares (10 billion acres) of forest remain, covering 31% of the Earth’s land surface. Only a third is primary. Much of the rest is seriously degraded: the FAO’s definition of a forest takes in areas with as little as 10% tree cover.

Almost half of the forest that remains is in the tropics, mostly as rainforest which, by almost any measure, is most precious of all. Nearly a third of that rainforest is in Brazil, which has two–thirds of the Amazon basin; and a fifth is in Congo and Indonesia. The second-biggest forest area, about a third of the total, is in the boreal, or taiga, biome: a belt of spruce, birch, fir and aspen that encircles the far northern hemisphere, mostly in Russia, Scandinavia, Finland, Canada and a small part of America. Just 11% of forest is in the temperate zone, dominated by America, which cleared almost half its massive forests in the 19th century, and Europe and China, which ate into theirs much earlier. Europe razed almost half its temperate oak-, beech- and birch-woods in the Middle Ages, an onslaught only briefly reversed by an outbreak of bubonic plague in the 14th century. Now temperate forests are creeping back. Over 7m hectares a year are currently being planted or allowed to regrow, according to the FAO, mostly in China and America.


A tropical problem

The current onslaught is mainly in the tropics. In the past six decades the rainforest has been reduced by over 60% and two-thirds of what remains is fragmented, which makes it even more liable to be cleared. And despite many campaigns by NGOs, vigils and rock concerts for the rainforest and efforts to buy it, lease it, log it and not log it, the destruction proceeds at a furious clip. In the past decade, the FAO records, around 13m hectares of the world’s forests, an area the size of England, have been lost each year. Most of this was tropical forest, razed for agriculture. But Russia, which has more forest than any other country, also lost a lot, which the FAO’s figures do not capture because its clearance did not involve a permanent change in land use. Between 2000 and 2005 some 144,000 sq km (55,500 square miles) of Russian forest—14% of the total—was incinerated or felled, much of it illegally.

This represents progress, of a sort. In the 1990s, when the candle-holding for the rainforest was at its height, over 16m hectares a year was lost. Most of the slowdown is because of reduced rates of clearance in the world’s biggest deforesters, Brazil and Indonesia, and to some degree this reflects their former gluttony: both have masses of cleared land to spare. But in both countries efforts to reduce the destruction have also helped, especially in Brazil, which has a fast-growing agricultural sector and is increasingly worried about deforestation. Over the past decade it has given protected status to 500,000 sq km of the Amazon rainforest. According to a recent report by the Royal Institute of International Affairs, a British think-tank, illegal logging has been greatly reduced in Brazil, Indonesia and Cameroon.

A few smaller rainforest countries are also showing more regard for their trees. Costa Rica, which in the late 1980s lost around 4% of its forest each year, has reduced its deforestation almost to zero. Gabon and Guyana, almost three-quarters of which are covered by trees, say that, with foreign help, they would be happy to keep it that way. Western consumers, increasingly sensitive to the notion of sustainability, have a small hand in these improvements. Alarmed by their bad press, Canadian timber companies announced in May this year that they would work with greens to improve the management of 72m hectares of boreal forest.

Yet such progress tends to be exaggerated, and even if it were real it would be insufficient because of two huge threats to the forest. The first is climate change, which is expected to redraw the map of forest ecosystems. The boreal forest will creep northwards, for example, as the permafrost thaws and carbon fertilisation increases. By one estimate, Finland’s forests could grow 44% faster as a result. But that is nothing to celebrate, because melting permafrost will release billions of tonnes of methane, an especially potent greenhouse gas. It will also be offset by an increase in forest dieback elsewhere, caused by rising aridity, drought, pests and fires—all symptoms of global warming. Deforestation, which causes local warming, exacerbates this. All this could make much of the current forest area inhospitable to trees.

Such damage is already more common than most climate models had predicted, with the boreal belt especially hard hit. Between 2000 and 2005 it lost 351,000 sq km of forest, mostly to fire and pests. Again, this loss does not show up in the FAO’s figures, and the resulting emissions are considered to be natural, not man-made. But the distinction is getting blurred. Setting aside its reforestation efforts, Canada, the world’s third-most-forested country, lost 5.2% of its tree cover in that five-year period. This was partly because of a plague of bark-beetles in its temperate and boreal zones, a record number of which have been surviving the recent mild winters. By 2009 they had devastated over 16m hectares of Canadian pine forest.

The outlook for the Amazon is also grave. Recent modelling suggests that the mutually reinforcing effects of increasing temperatures and aridity, forest fires and deforestation could bring the rainforest far closer than previously thought to “tipping points” at which it becomes ecologically unviable. So far 18% of the rainforest has been cleared. The loss of another 2%, according to a World Bank study last year, could start to trigger dieback in the forest’s relatively dry southern and south-eastern parts. A global temperature increase of 3.5%, comfortably within the current range of estimates for the end of this century, would put paid to half the rainforest. This would release much of the 50 gigatonnes of carbon it is estimated to contain—equivalent to ten years of global emissions from burning fossil fuels.

Too many hungry mouths

The second great threat is human. The Earth’s population is expected to increase by half over the next four decades, to around 9 billion, and most of the additional 3 billion-odd hungry mouths will be in developing countries, especially tropical ones. The population of Congo, now 70m, will double in that time. Demand for food in these countries will also double, which, at their current low levels of agricultural productivity, will drive up demand for forest land.

As in most central African countries, Congo’s deforestation is currently minor, caused largely by small-scale shifting cultivation and over-harvesting of wood for fuel. At present the country has little commercial agriculture or logging because of the state of its infrastructure, ruined by war and misrule. Indeed, the decay of Congo’s Belgian-built roads, which in 1960 ran to over 100,000km, must rank as one of the greatest boons to forests since the Black Death. In the thick forest-savannah mosaic of northern Congo, many days’ walk from any tarmac, your correspondent unearthed a milestone, half-buried in the leaf-litter, pointing to the small town of Badai, 15km to the east. Buried deeper was the gravel highway that once led there.

But Africa is an outlier. Most tropical deforestation is the result of expanding commercial ranching and agriculture, driven by rocketing domestic and global demand for food, fibre and biofuel. In Indonesia, oil palm, a productive source of cooking oil and biodiesel, offers the biggest reason to clear. Between 2000 and 2006 Indonesia planted roughly half a million hectares of oil palm a year, mostly on recently deforested land. The clearance in Brazil, which is mostly illegal, is mainly for pasture; the Amazonian cattle-herd has grown by over 40m head in the past two decades. The explosive recent growth in the cultivation of another oil seed, soyabean, has led to an onslaught on Brazil’s dryland cerrado savannah, which is often disregarded as a forest, though it contains two-thirds as much carbon as the rainforest, mostly in its roots. By moving northwards into the Amazon basin, soya farmers are also driving ranchers deeper into the rainforest.

Grim climate predictions and recent food-price inflation have led to growing fears for food security, adding to the pressure. Foreign governments and investors are increasingly on the lookout to buy cheap, well-watered tropical land. Last year the Saudi Binladin Group tried, unsuccessfully, to secure land in Indonesia’s island of Papua where it wanted to invest $4.3 billion in rice cultivation. China, which has agreed to build and renovate 6,000km of roads in Congo, reportedly wants to cultivate oil palm there on a massive scale. It is the world’s biggest importer of palm oil and global demand for the stuff is soaring, even before much is getting converted into biodiesel, as increasingly it will. And wherever there is such demand for tropical agribusiness, forests are being razed to meet it. Securing a licence to clear rainforest is often easier than buying up and consolidating smallholdings.

What hope of survival have forests, especially the tropical sort, most precious and most threatened? Large-scale defences are now being marshalled by governments, NGOs, scientists and investors, chief among them an international endeavour known as Reduced Emissions from Deforestation and Forest Degradation, or REDD. Launched with $4.5 billion, it is based on the idea that rich countries should pay poorer ones not to cut down trees. Yet there is a big risk that REDD will deliver much less than is required.

The Earth’s need for forests to soak up carbon emissions is almost limitless. Saving the forest that is left should therefore be considered a modest aim. But even that will require huge improvements in forest management, such as reforming land registries and tightening up law enforcement. Above all, it will require governments to prize forest very much more highly than they do now. Otherwise there will be no chance of the many reforms required outside the forestry sector: in land-use planning and rural development, in agriculture, energy and infrastructure policies, and much else. It will also require politicians to get serious about climate change. All that amounts to a revolution, which is a lot to hope for. But if anything can help bring it about, forests might.

They are crucial in all sorts of ways because of the manifold services they provide. Western taxpayers need the Amazon rainforest to control their climate. Brazil needs it to help feed its rivers and generate hydro-power. Amazonian soya farmers need it to guarantee them decent rainfall. Yet policies at every level conspire to wreak its destruction. Changing them, in Brazil and across the tropical world, is a daunting task. But it is not impossible—and it must be done. The cost of failure would simply be too great.

The growth of the forest carbon market in 2009, despite the recession!

September 6, 2010 § Leave a comment

One of the key influences for protecting our rainforests today and in the near future is the successful growth of the forest carbon market. As it puts a clear financial structure in place for industries to pay for the protection of rainforest and the environmental services they provide globally.

From 2007 through the first half of 2009 alone, forest carbon markets have funneled roughly $100 million into forestry conservation projects around the world, transacting 20.8 million MtCO2 in the process. In dollar terms, this period represents 67% of the market value of all forest carbon offsets, due to higher volumes and prices associated with emerging interest in the voluntary carbon markets overall, along with maturing standards and infrastructure.

The forest carbon market is now two decades old but the bulk of its 20-million-tonne contribution to carbon sequestration and emissions reduction has come in the last three years – despite the global financial crisis and recession. This picture emerges from the ‘State of the Forest Carbon Markets’ report released by Ecosystem Marketplace (ESM). Its landmark report appears the best attempt yet at a comprehensive estimate of the volumes and value in the forest carbon sector worldwide.
