Illegal logging continues to plague Madagascar’s rainforest parks


Despite government assurances that it would crack down on the rosewood trade, illegal logging continues in Madagascar’s rainforest parks, according to new information provided by sources on the ground and reported in Wildmadagascar.com.

The sources report logging in three parks: Mananara, Makira, and Masoala. All three are known for their high levels of biodiversity, including endangered lemurs.

Rosewood logs are being transported to Tamatave (Toamasina), Madagascar’s main port, despite a national moratorium on logging and export of precious hardwoods. Most rosewood ends up going to China, where it is in high demand for furniture.

The Malagasy sources report that local law enforcement—the new Brigade Mixte Forestière established to reduce logging—is impeded the Forest Ministry, which has failed to grant them the right to use search warrants on private property.

The sources also claim that rosewood confiscated by authorities is being stolen from official stockpiles.

Illegal logging exploded last year in the aftermath of a military coup that displaced the democratically-elected, but increasingly autocratic president, Marc Ravalomanana.

National parks, especially in the North-East of the country, were ransacked by loggers employed by timber barons who traditionally capitalize on political instability or natural disasters to replenish timber stocks and traffic ill-gotten wood.

Madagascar is now ruled by a “transition authority” that has so far shown little inclination to hold free and fair elections and has been be slow to address the logging crisis despite pressure from the international community.

China timber sector looks at tougher EU/US import rules


The China Timber and Wood Products Circulation Association (CTWPCA) is seeking to establish a body to help importers navigate new environmental regulations in the US and EU that restrict trade in illegally logged timber, reports the International Tropical Timber Organization (ITTO).

In a recent market report, ITTO said that Chinese importers fear failing to meet the new regulations that govern the sourcing of timber products.

The US’s Lacey Act and the EU’s FLEGT ruling put the burden of responsibility on importing companies, holding them to the environmental laws of producing countries.

Companies found to be sourcing illegally logged timber could be subject to fines or worse.

A company accused of using illicit rosewood from Madagascar, was the first company to be charged and investigated under the Lacey Act.

The legislation was amended in 2008 to include “anyone who imported, exported, transported, sold, received, acquired or purchased the wood products made from that illegal timber, who knew or should have known that the wood was illegal.” The firm’s case is pending.

According to ITTO, CTWPCA believes traders need “guidance and support” on the new international requirements.

The body would also set up a “responsible procurement system” for timber imports, seek to address corruption in the timber import and trade sector, and aim to help Chinese timber traders meet international standards.

China already has guidelines governing Chinese companies operating forest concessions overseas.

These compel companies to abide by local environmental laws and take measures to reduce pollution. However, some observers suggest that there is no indication that these mandatory rules are being enforced.

REDD+ could do more harm than good, forestry experts warn


As governments across Latin America prepare to implement a new financial mechanism aimed at mitigating climate change by curbing carbon emissions from the destruction of tropical forests, experts have warned against a “one-size-fits-all” approach.

Instead, they are calling for flexible, balanced solutions to the surrounding this new mechanism.

Among the experts’ main concerns are that the wealthy and powerful could capture many of the benefits, largely at the expense of rural communities, including indigenous groups.

Organised by Mexico’s National Forestry Commission and the Swiss government, with scientific support from the Center for International Forestry Research (CIFOR), a recent conference’s findings and recommendations will be feed into a UN Forum on Forests (UNFF) meeting scheduled to take place in early 2011, marking the launch of the International Year of Forests.

The Mexico gathering brought together scientists, as well as representatives of governments and non-government organisations, for discussions on governance, decentralisation and REDD+ in Latin America.

Under REDD+ (for reducing deforestation and forest degradation), industrialised countries will provide developing nations with sizeable sums of money in exchange for verifiable storage of carbon in forests, in addition to the conservation and sustainable management of forests.

Forest destruction currently accounts for up to 18% of annual global carbon emissions. Several Latin American countries, including Mexico, have taken the lead in designing REDD+ schemes and stand to benefit significantly.

“Good forest governance – involving transparent and inclusive relationships between governments, forests and the people who depend on them – is fundamental for ensuring that REDD+ helps forest-dependent communities move out of poverty, instead of fueling corruption and funding entrenched bureaucracies,” said Elena Petkova, a CIFOR scientist.

“REDD+ schemes could either flounder on governance failures or flourish under successful governance.”

The central aim of the conference in Oaxaca was to provide science-based advice on the design and implementation of REDD+ schemes, so these schemes can capture carbon and reduce emissions effectively, while at the same time generate significant benefits from sustainable forest management that are equitably shared.

“About 40 years of public sector investment in curbing deforestation, while producing many local successes, has fallen far short of its goal,” said another CIFOR scientist, Andrew Wardell, who was also attending the conference.

“REDD+ might be our last chance to save the world’s tropical forests. So, it’s extremely important to get it right in Latin America and elsewhere.

“This region holds nearly a quarter of the world’s forests, upon which millions of people depend, and over the last five years, it has accounted for 65% percent of global net forest loss.”

North Korea begins agroforestry scheme to halt degradation


A “pioneering agroforestry project” in North Korea is restoring heavily degraded landscapes and providing much-needed food for communities, says the World Agroforestry Centre.

Jianchu Xu, the Centre’s East-Asia co-ordinator,  said agroforestry – in this case the growing of trees on sloping land – was uniquely suited to DPR Korea for addressing food security and protecting the environment.

“What we have managed to achieve so far has had a dramatic impact on people’s lives and the local environment,” he explained.

“Previously malnourished communities are now producing their own trees and growing chestnut, walnut, peaches, pears and other fruits and berries as well as medicinal bushes.”

Following the collapse of the socialist bloc in 1989 and a lack of subsidies for agriculture in DPR Korea, famine and malnutrition became widespread in rural areas.

DPR Korea is a harsh mountainous country where only 16% of the land area is suitable for cultivation, data from the Centre suggests.

It addded that out of  desperation in the 1990s, people turned to the marginal sloping lands but this had a price: deforestation for cropping land and fuelwood left entire landscapes denuded and depleted of nutrients.

In an attempt to reverse the situation, an innovative project began in 2002 involving the Swiss Agency for Development and Cooperation (SDC) and Korea’s Ministry of Land and Environmental Protection. The World Agroforestry Centre was later brought in to provide technical advice.

A system of establishing user groups with one representative from each family enabled demonstration plots to be set up and a large number of households have benefited from knowledge about growing multi-purpose trees.

Using these types of trees have helped  improve and stabilise soils, as well as provide fertilizer, fodder or fruits.

To further support the development of appopriate skills in North Korea, the World Agroforestry Centre has announced plans to publish an agroforestry manual.

The Centre added that work was also underway to develop an agroforestry policy for sloping lands management, as well as establishing an agroforestry inventory.

Trying to curb the appetite of tree-hungry chopsticks


For the humble chopstick, life is predictable, reports Alice-Azania Jarvis in the Independent newspaper.

Start off as a tree, one of the 25 million felled each year for the purpose. Spend a brief few weeks, newly-whittled, encased in paper. Then wind up on someone’s plate, where you are expertly used to shovel noodles, or rice, or meat into a mouth.

Then that’s it. It’s time to face the great landfill in the sky. Millions of chopsticks meet their end like this. In fact, billions – 45 billion a year in China alone, taking with them some 100 acres of birch, poplar and bamboo forest a day.

It is one reason why attempts are under way to turn the Chinese off their disposable cutlery and on to the longer-lasting kind.

In 2006, the Government introduced a 5% tax on all disposable wooden chopsticks following petitions from schoolchildren and citizens’ group.

Since then, efforts to curb the wooden sticks’ use have increased. A BYOC (Bring Your Own Chopsticks) movement has been actively petitioning for sustainable options for some time.

Described by the China Post as a collection of “young yuppies”, they carry around their own implements when dining out. Occasionally, claims the Post, restaurant owners take it upon themselves to reward the yuppies’ efforts with a complimentary bowl of soup.

Greenpeace launched a campaign with the slogan “say no to disposable chopsticks.” In 2008, activists dressed as orang-utans invaded corporate cafeterias – Microsoft, Intel and IBM among them – to discourage diners from going disposable.

Then, earlier this year, the Chinese Ministry of Commerce joined with five other government departments to warn that companies using disposables could soon face legal restrictions. They claimed to “aim at decreasing the use of the throwaway utensil”.

“Production, circulation and recycling of disposable chopsticks should be more strictly supervised,” they explained.

It’s a stark about-face for the Chinese government. Prior to the measure, they had actively encouraged disposables’ use. They were, reasoned authorities, more hygienic that their reusable cousins.

The debate over throwaway instruments, while raging in China, is by no means limited to chopsticks.

In the UK, disposable cutlery is thought to be used for an average of three minutes before being discarded.

Plastics – including convenience cutlery, crockery and cups – account for 7% of office waste. That’s before the countless millions of knives, forks and spoons churned out by fast food restaurants, cafes and supermarkets are taken into account.

Recent years have seen the rise of the Carry Your Own Cutlery (CYOC) movement, while websites such as recyclethis.co.uk offer readers advice on how to reuse their plastic implements.

Increasingly, retailers are under pressure to offer – if not reusable – then at least recyclable options.

Starbucks recently pledged to introduce renewable materials during its next round of store upgrades and has committed to using entirely recyclable cups by 2015. Pret-a-Manger, meanwhile, has pledged to go “landfill-free” by 2012.

Not everyone has been so quick to change. McDonald’s, while using recycled paper in much of its packaging, defends its choice of plastic cutlery on the grounds that washing up would waste energy.

How effective China’s measures will be remains to be seen. The BYOC has been slow in picking up active support, and the government’s waste warning, while a step in an environmentally-friendly direction, is more bark than bite.

Legislation is looming, though as yet there are few concrete incentives for diners to trade in their disposables. Wooden chopsticks cost restaurant owners a fraction of what the more durable alternatives do, since the cost of sterilisation is high.

What’s more, the alternative melamine-resin chopsticks have a notoriously high formaldehyde content, which is neither great news for the environment nor diners’ health.

Polls by news outlets have found broad support for reusable items. Some 84.2% of participants told a recent Sina.com poll that they would swap for more durable options.

Still, analysts point out that the authorities’ interest is divided: environmentally, cutting down on chopsticks makes sense; economically – in the short term at least – it doesn’t.

More than 300,000 people are employed by the wooden chopstick industry, across 300 factories. Exports of their wares bring in $200m a year.

In 2009, it was claimed that 300 restaurants in Beijing had ceased to provide disposable chopsticks. In a country of some 1.3 billion diners, there’s a long way left to go.

Model shows ‘waves of forest degradation’


An international team of researchers has developed a model that suggests degradation of tropical forests occurs in a series of “waves”, reports the BBC News website’s Mark Kinver.

High-value trees were felled in the first “wave”, followed by a wave that removed mid-value timber before the remaining wood was felled for charcoal.

The team hopes the model will help manage forests as vital carbon sinks and limit the loss of biodiversity.

The findings appear in the Proceedings of the National Academy of Sciences.

The researchers said an economic theory was used to provide a general model to predict patterns of tree loss.

This translates to a prediction that waves of forest degradation will emanate from major demand centres and expand into nearby forested areas, targeting resources in sequence, starting with those of highest value,” they wrote in their PNAS paper.

“Such a sequence of demand, linked to resource utilisation, has been demonstrated for unmanaged fisheries… but has not been shown for the exploitation of differently valued tropical forest products.”

The team used data collected in the area surrounding Tanzania’s largest city, Dar es Salaam, to see how far the degradation “waves” had travelled between 1991 and 2005.

“The first wave that emanates is high-value timber, and that is mostly used for export,” explained co-author Antje Ahrends, an ecologist at the Royal Botanical Garden, Edinburgh.

“There has been a massive demand for this in China, and this is where most of the timber ends up.”

Dr Ahrends said the first wave moved out from Dar es Salaam rapidly, averaging about nine kilometres each year, because the “timber companies had lorries and loads of people working for them”.

“For the firms, it is only worthwhile to stay in a forest when timber can be accessed relatively easily,” she told BBC News.

“So once it becomes not so easy to get hold of the rest, the companies generally move on.”

The first wave had already moved outside of the team’s study area, and Dr Ahrends estimated that it was already more than 200km from Dar es Salaam.

The second wave saw trees being felled for medium-valued timber, which was generally used in the city for construction and furniture.

“This is expanding very rapidly, in line with urban migration,” she explained. “The town has an average growth rate of about 7% each year, so there is – again – a rapidly growing demand for this material.”

The timber is harvested by local companies, again with lorries, allowing large volumes to be collected in a relatively short space of time. This resulted in this degradation wave to also cover about nine kilometres each year.

The third and final wave involved local people collecting wood to make charcoal for cooking.

“It’s the most destructive of all of the waves because charcoal burners would collect everything,” observed Dr Ahrends, who was based at the York Institute for Tropical Ecosystem Dynamics when she carried out this research.

“It is only worthwhile moving on once there are no sizeable trees left in the forest.”

As a result, the charcoal wave had moved relatively slowly – from 20km outside Dar es Salaam in 1991 to 50km away in 2005.

“It is the most difficult of the waves to tackle because it is very poor people who burn charcoal and their livelihoods depend upon it.”

“Targeting that wave would mean trying to provide alternative resources for cooking, and alternative incomes for people who burn charcoal.

Species loss

The team also developed their model to gauge what impact forest degradation had on “public good” services, such as carbon storage and biodiversity.

They did this by recording what species of trees were in a particular area of the study, and what size the individual trees were.

“This later enabled us to calculate species richness and also the amount of carbon those trees were storing,” Dr Ahrends said.

“We found that there was a very strong linear impacts; for example, tree species richness dropped to only 14 species-per-sample-unit close to Dar es Salaam, whereas it is more than 40 species in areas 200km away.”

Dr Ahrends suggested that the model could be used to understand the impact of forest degradation in other sub-Sarahan nations in Africa.

“This is because conditions are very similar: high levels of corruption, weak law enforcement and very rapid rates of urbanisation.”

She added that the team’s model could help policymakers who were looking at ways to limit deforestation rates.

“What is really important is to understand the pattern of degradation and the way it spreads,” she suggested.

“While we have a good understanding of deforestation – which is the complete clearance of a forest – it is much more difficult to measure degradation.

“So if you have this simple model, then you have a basic understanding of how degradation might spread… which may help you develop some prediction of where it might spread from and how far it might spread.”

Indonesia ‘failing on pledge to reduce forest fires’


The Indonesian government failed to live up to its promises to reduce fires across the tropical nation last year, reports Mongabay.com.Take Cover library picture

It quotes The Jakarta Post as saying that the nation’s 2009 State Environment Report revealed a 59% increase in the number of fire hotspots from 19,192 in 2008 to 32,416 last year.

Officials are reported as saying that land clearing was the primary cause because, unlike temperature forests, intact rainforests rarely burn naturally.

“Illegal land clearing with fires by local people in Kalimantan and Sumatra is still rampant,” Heddy Mukna, deputy assistant for forest and land management at the Environment Ministry told the Post.

The state of Kalimantan on the island of Borneo saw fires triple in some areas from 2008 to 2009.

Haze blanketed much of the island last year during the “burning season”.

In 2007, the Indonesian government announced plan to cut forest fires in half to mitigate climate change from 35,279 fires in 2006.

The government has since revised that reduction from 50% to just 20%.

Indonesia is the third largest emitter of greenhouse gases in the world behind China and the US.

An estimated 80% of the nation’s 2.3 billion tonnes of greenhouse gas emissions is from rainforest and peatland destruction.

Amazon forest fires ‘on the rise’


The number of fires destroying Amazon rainforests are increasing, a study has found.

Take Cover library pictureThe BBC’s Mark Kinver reports that a team of scientists said fires in the region could release similar amounts of carbon as deliberate deforestation.

Reporting on a paper published in the journal Science, Kinver says the researchers found that that fire occurrence rates had increased in 59% of areas with reduced deforestation.

As a result, the rise in fires could jeopardise the long-term success of schemes to reduce emissions from deforestation, they added.

The researchers – from the University of Exeter, UK, and Brazil’s National Institute for Space Research – based their findings on satellite-derived data on deforestation and forest fires.

“The results were a surprise because we expected that fires would have decreased with the decrease of deforestation,” said co-author Luiz Aragao from the University of Exeter.

“The implication for REDD is that we first need a system that can monitor fires,” he told the Science journal.

“There is also a need to shift land use in the Amazon to a system where fire is not used.”

‘Slash and burn’

REDD (Reducing Emissions from Deforestation and forest Degradation) schemes aim to create a financil value for the carbon stored in developing nations’ tropical forests.

It offers nations incentives to protect forest areas from a variety of impacts that release carbon into the atmosphere, including tree felling and logging, agricultural expansion, land degradation.

As deforestation accounts for about 20% of emissions resulting from human activity, the REDD programmes are considered to be a key component in the global effort to curb climate change.

“Fires following drought years are likely to release a similar amount of carbon as emissions from deliberate deforestation,” the researchers wrote.

“The higher probability of a drier Amazon in the 21st Century predicted by some global circulation models… may push Amazonia towards an amplified fire-prone system.”

They added that previous studies showed that fires in the region increased after large-scale droughts in 1998 and 2005.

“Forest landscapes in Amazonia are becoming more fragmented and, therefore, a growing proportion of forests is exposed to the leakage of accidental fires from adjacent farms,” they suggested.

The practice of “slash and burn” is widely used by farmers in the Amazon region to clear secondary forests and allow food and cash crops to be cultivated.

But Dr Aragao said: “We need to change the way people use and manage their land so that they can do this without fire.”

Commenting on the paper’s findings, Andrew Mitchell, director of the Global Canopy Programme, said: “These results have important implications for REDD negotiations.

“If we are to control deforestation, you have got to look at what local people are doing outside of the forests,” he told BBC News.

“The entire REDD regime need to encourage a better use of land without fire.

“But if they do not use fire, which is cheap, then what are they going to use – strimmers? Chainsaws? Tractors?

“That means that money from REDD programmes need to go to people that not only live within the forests, but also the farmers living outside them.”

Dr Aragao agreed, adding that switching to fire-free land management in already deforested area that lie next to forests could “drastically reduce fires and carbon emissions”.

“It would be expensive,” he observed, “but it would protect the stability of Amazonian carbon stocks and diversity.”

Pieter van Lierop, a forestry officer for the Food and Agriculture Organization (FA) – a member of the UN’s REDD programme, said the findings were relevant to policies aimed at reducing deforestation.

“The article clearly demonstrates that within REDD, specific attention should go to analyzing the role of fire and propose more responsible use of fire and/or alternatives for fire,” he told BBC News.

“However, we should also take into consideration that the article is mainly discussing fire incidence and occurence, meaning number of fires and not the size of emissions.”

Study finds 25 news beetle species on Turkey’s oaks


Twenty-five hitherto unknown species of beetle have been found on the Turkey’s oak trees, according to a study by Swedish researchers.

Take Cover library picture“Most of them would disappear if the trees were to be cut down, and the risk is great”, says project leader Nicklas Jansson, beetle ecologist at Linkoping University (LiU) in Sweden.

In Turkey, there are 18 species of the oak family, and Dr Jansson and his research team spent five years collecting beetles from oak trees in four large pastures in the south of the country.

They said the study areas – 1,200-1,500 metres above sea level – were important for sheep and goat farming, but were now threatened by felling to make way for productive forest management.

They warned that as with all felling there is a major risk that some species become extinct since the oak dwelling beetles stay so faithful to their biotope.

“Some of the species seem to have a very low motivation to leave and find a new oak,” Dr Jansson observed.

Most of the newly discovered beetles belong to the Elateridae and Tenobrionidae families and have been identified by some 20 specialists across Europe.

The results were presented at a conference on oak ecology in Isparta, Turkey.

The researchers identified a number of factors that could be responsible for the greater diversity of beetles:

  • a climate that allowed species to hibernate during the Ice Ages
  • the topography which creates many barriers in the form of mountain ranges and other obstacles to the mixing of species
  • the geographic location as a bridge between Asia and Europe.

In a follow-up project, the research team planned to compare the oak fauna of seven countries, including Israel, Turkey, Italy, France, the UK  and Sweden.

The oaks in the Turkish pastures are pollarded. Shepherd people prune the trees in July and during the dry season use the leaves as feed for sheep and goats while the branches become fuel.

As a result of pollarding, many of the oaks were hollow and contain wood mould, a very rich compost of decomposed wood, fungi, excrement and remains of dead animals.

“I hope that in finding new and unique species we will get the Turkish forestry authorities to open their eyes to their oak treasures and to begin conservation work in the most valuable areas,” Dr Jansson explained.

EU and Congo deal ‘to curb illegal timber trade’


The European Union and the Republic of Congo have announced a new agreement to ensure wood products exported from the Republic of Congo to the EU contain no illegally harvested timber and are derived from managed forests, says the European Forest Institute.

Congo exports about $330 million in timber products each year, about half of which are purchased by EU countries.

Italy, Spain, Portugal, France, Germany, the Netherlands and Belgium are the principle EU importers, but it has been difficult to confirm whether the produce has been derived from timber harvested legally, and the benefits from timber sales are shared with forest communities.

“With a total of 4,674,320 acres of certified forests as of March 2009, Congo has reached the highest echelon of tropical wood producing countries and is becoming a laboratory for sustainable forest management,” said Henri Djombo, Congo’s Minister of Forest Economy.

“The conclusion of this agreement will guarantee our country new opportunities in timber markets while participating in reinforcing governance in that sector and illustrating Congo’s political commitment to work in that direction.”

The legally binding agreement is known as a Voluntary Partnership Agreement (VPA), which stems from European Commission’s 2003 Action Plan on Forest Law Enforcement, Governance and Trade (FLEGT) that is designed to halt the flow of illegal timber into EU markets.

It is the culmination of several years of work between the EU, the government of Republic of Congo, and NGOs that, rather than impose EU standards, allows the national government and various stakeholder groups to establish their own system for defining and enforcing legal requirements for timber sales.

Climate ‘adds fuel to Asian wildfire emissions’


In the last decade, Asian farmers have cleared tens of thousands of square miles of forests to accommodate the world’s growing demand for palm oil, an increasingly popular food ingredient, reports Science Daily.

Ancient peatlands have been drained and lush tropical forests have been cut down.

As a result, the landscape of equatorial Asia now lies vulnerable to fires, which are growing more frequent and having a serious impact on the air as well as the land.

A team of NASA-sponsored researchers have used satellites to make the first series of estimates of carbon dioxide (CO2) emitted from these fires — both wildfires and fires started by people — in Malaysia, Indonesia, Borneo, and Papua New Guinea.

They are now working to understand how climate influences the spread and intensity of the fires.

Using data from a carbon-detecting NASA satellite and computer models, the researchers found that seasonal fires from 2000 to 2006 doubled the amount of carbon dioxide (CO2) released from the Earth to the atmosphere above the region.

The scientists also observed through satellite remote sensing that fires in regional peatlands and forests burned longer and emitted ten times more carbon when rainfall declined by one third the normal amount.

The results were presented in December 2008 in Proceedings of the National Academy of Sciences.

Tropical Asian fires first grabbed the attention of government officials, media, and conservationists in 1997, when fires set to clear land for palm oil and rice plantations burned out of control.

The fires turned wild and spread to dry, flammable peatlands during one of the region’s driest seasons on record. By the time the flames subsided in early 1998, emissions from the fires had reached 40 percent of the global carbon emissions for the period.

“In this region, decision makers are facing a dichotomy of demands, as expanding commercial crop production is competing with efforts to ease the environmental impact of fires,” said co-author Jim Collatz, an Earth scientist at NASA’s Goddard Space Flight Center.

“The science is telling us that we need strategies to reduce the occurrence of deforestation fires and peatlands wildfires. Without some new strategies, emissions from the region could rise substantially in a drier, warmer future.”

Since the 1997 event, the region has been hit by two major dry spells and a steady upswing in fires, threatening biodiversity and air quality and contributing to the buildup of CO2 in the atmosphere.

As more CO2 is emitted, the global atmosphere traps more heat near Earth’s surface, leading to more drying and more fires.

Until recently, scientists knew little about what drives changes in how fires spread and how long they burn. Dr Collatz, along with lead author Guido van der Werf of Vrije University, Amsterdam, and other colleagues sought to estimate the emissions since the devastating 1997-98 fires and to analyse the interplay between the fires and drought.

They used the carbon monoxide detecting Measurements of Pollution in the Troposphere (MOPITT) instrument on NASA’s Terra satellite — as well as 1997-2006 fire data and research computer models — to screen for and differentiate between carbon emissions from deforestation versus general emissions.

Carbon monoxide is a good indicator of the occurrence of fire, and the amounts of carbon monoxide in fire emissions are related to the amount of carbon dioxide.

They also compared the emissions from different types of plant life (peat land verses typical forest) by examining changes in land cover and land use as viewed by Terra’s Moderate Resolution Imaging Spectradiometer (MODIS) and by Landsat 7.

Collatz explained that two climate phenomena drive regional drought.

El Nino’s warm waters in the Eastern Pacific change weather patterns around the world every few years and cause cooler water temperatures in the western Pacific near equatorial Asia that suppress the convection necessary for rainfall.

Previously, scientists have used measurements from NASA’s Tropical Rainfall Measurement Mission satellite to correlate rainfall with carbon losses and burned land data, finding that wildfire emissions rose during dry El Nino seasons.

The Indian Ocean dipole phenomenon affects climate in the Indian Ocean region with oscillating ocean temperatures characterized by warmer waters merging with colder waters to inhibit rainfall over Indonesia, Borneo, and their neighbors.

“This link between drought and emissions should be of concern to all of us,” said co-author Ruth DeFries, an ecologist at Columbia University in New York.

“If drought becomes more frequent with climate change, we can expect more fires.”

Collatz, DeFries, and their colleagues found that between 2000 and 2006, the average carbon dioxide emissions from equatorial Asia accounted for about 2 percent of global fossil fuel emissions and 3 percent of the global increase in atmospheric CO2.

But during moderate El Nino years in 2002 and 2006, when dry season rainfall was half of normal, fire emissions rose by a factor of 10. During the severe El Nino of 1997-1998, fire emissions from this region comprised 15% of global fossil fuel emissions and 31% of the global atmospheric increase over that period.

“This study not only updates our measurements of carbon losses from these fires, but also highlights an increasingly important factor driving change in equatorial Asia,” explained DeFries.

“In this part of Asia, human-ignited forest and peat fires are emitting excessive carbon into the atmosphere. In climate-sensitive areas like Borneo, human response to drought is a new dynamic affecting feedbacks between climate and the carbon cycle.”

In addition to climate influences, human activities contribute to the growing fire emissions.

Palm oil is increasingly grown for use as a cooking oil and biofuel, while also replacing trans fats in processed foods.

It has become the most widely produced edible oil in the world, and production has swelled in recent years to surpass that of soybean oil.

More than 30 million tonnes of palm oil are produced in Malaysia and Indonesia alone, and the two countries now supply more than 85% of global demand.

The environmental effects of such growth have been significant. Land has to be cleared to grow the crop, and the preferred method is fire.

The clearing often occurs in drained peatlands that are otherwise swampy forests where the remains of past plant life have been submerged for centuries in as much as 60 feet of water.

Peat material in Borneo, for example, stores the equivalent of about nine years worth of global fossil fuel emissions.

“Indonesia has become the third largest greenhouse gas emitter after the United States and China, as a result primarily to these fire emissions,” Collatz said.

“With an extended dry season, the peat surface dries out, catches fire, and the lack of rainfall can keep the fires going for months.”

Besides emitting carbon, the agricultural fires and related wildfires also ravage delicate ecosystems in conservation hotspots like the western Pacific island of Borneo, home to more than 15,000 species of plants, 240 species of trees, and an abundance of endangered animals.

Smoke and other fire emissions also regularly taint regional air quality to such a degree that officials have to close schools and airports out of concern for public health and safety.

Peat fires also aggravate air pollution problems in this region because they release four times more carbon monoxide than forest fires.

In 1997, air pollution from the fires cost the region an estimated $4.5 billion in tourism and business.

‘Green Nobel’ for rainforest champion


A campaigner who was jailed during his battle to save the rainforest in Gabon has received a top international award., reports the BBC’s Victoria Gill.

Marc Ona Essangui was honoured for his fight to stop what he describes as a destructive mining project in the Ivindo National Park.

He is one of seven people from six continental regions to be awarded an equal share of the $900,000 (£600,000) 2009 Goldman Environmental Prize.

It has been described as “the Nobel Prize for grassroots environmentalism”.

Mr Ona has campaigned for three years against the Belinga mine project – a deal between the government in Gabon and the Chinese mining and engineering company, CMEC, to extract iron ore.

The project includes the construction of a large hydroelectric dam, which is already underway, to provide power for the mine. The dam is being built on the Ivindo River, near the Kongou Falls, Gabon’s highest waterfall.

Mr Ona, who described the falls as “the most beautiful in central Africa”, said that Gabon’s government had failed to consult the local population and had not assessed the impact of the development on the environment before it gave permission for construction to begin.

He told BBC News that he hoped his receipt of the Goldman Prize would “draw international attention to just how precious this area is”.

Mr Ona, who uses a wheelchair, dedicated his early career to improving education and communication infrastructure in Gabon, including working with the United Nations Development Programme. He later turned his attention to environmental issues.

He eventually decided to focus his efforts full time on the work of his own environmental NGO, Brainforest, which aims to protect the rainforest for the benefit local of communities.

“The government established 13 national parks here, and I became interested in all the activities within them,” he said.

“In 2006, my colleagues and I noticed that roads were being built within Ivindo.”

When Mr Ona investigated, he discovered that there had been no environmental impact studies carried out before the road building started.

On its website, the Gabonese government describes the national parks as having been “classified for the conservation of Gabon’s rich biodiversity”.

The key goals of the national park scheme, it says, are preservation of “the wealth of the ecosystem… for current and future generations” and stimulating “the development of ecotourism as an economic alternative to the exploitation of natural resources”.

Mr Ona said: “All of this construction was carried out illegally and against the code of the national parks.”

He also unearthed and leaked a copy of the Belinga mine project agreement between the government and CMEC, revealing that CMEC had been offered a 25-year tax break as part of the deal.

“When we really started to look into the deal, we noticed that it was China, not Gabon, that was the major beneficiary,” he said.

He and his colleagues embarked on their campaign, working with other environmental NGOs, holding news conferences and meeting with local communities.

“The government even motivated some protests against the NGOs involved,” he recalled.

“They alleged that we were working [on behalf of] Western powers, and we received a lot of pressure to stop the campaign.”

This culminated in Mr Ona being arrested and charged with “incitement to rebellion”.

He was jailed by the Gabonese judicial police on 31 December 2008; but following an internationally co-ordinated campaign for his release, he was freed on 12 January 2009.

Since June 2006, however, he has been banned from travelling outside the country.

His passport was returned to him only 24 hours before he was due to travel to San Francisco for the Goldman award ceremony.

There has been no construction in Ivindo for almost a year, but Mr Ona says this has more to do with the economic crisis and the price of iron ore than with the Gabonese government backing down.

He has no plans to give up his quest.

“Some of the money from this award will go to the functioning of Brainforest, and the rest will be allocated to setting up small- and medium-sized businesses for local communities,” he said.

“I want to set up a clinic near Ivindo where the local people can be treated using traditional medicine. Some of the money will serve to establish this health centre for all of those communities.”

The organisers of the Goldman Prize describe the six winners as “a group of fearless grassroots leaders, taking on government and corporate interests and working to improve the environment for people in their communities”.

Tree planting in the driest place on Earth


The southern coast of Peru is one of the driest places on Earth. Why would anyone choose this parched location to re-plant a forest, asks the BBC’s John Walton.

The strip of desert between the Andean mountains and the Pacific Ocean has an annual average rainfall as low as 1.5mm.

By way of comparison, London enjoys around 650mm a year.

It’s not an obvious place to choose if you’re looking for somewhere to plant trees, but for restoration ecologist Oliver Whaley the harsh environment of the northern fringes of the Atacama desert is part of the point.

By helping to restore the shrinking native forests, the aim is to benefit local people and wildlife, prevent soil erosion, and help alleviate climate change.

“If we can get trees established here, and learn how to do it with as little water as possible, then it is a model for the rest of the world,” he says.

While the plight of the world’s rainforests are well known, the same cannot be said of tropical dry forests. These less biodiverse, but equally remarkable forests, face threats every bit as severe as their better known cousins.

The Atacama dry forest “is really an ecosystem on its last legs,” says Mr Whaley, of London’s Kew Gardens – an internationally renowned botanical research institution.

The tree under threat is the huarango, Prosopis limensis, found only in the Ica region of Peru.

In this parched landscape, the hardy huarango is no stranger to thirst. Although rain seldom falls, it is able to capture moisture from other sources – trapping fog on its leaves, directing the water downwards towards its roots. The roots themselves are among the longest of any plant – 50m to 80m – and seek out underground water sources that flow from the Andes.

The huarango is also a valuable source of food and fuel, and a keystone of the local ecosystem. Whaley estimates that when he arrived in Peru, just 1% of the original local forest habitat remained – much of it consumed in charcoal production.

The problems facing dry forest habitat are not unique to Peru. Restoration expert James Aronson says, in general, these are more critically endangered than wet tropical forests, in respect of the total percentage already lost.

Mr Aronson, who heads the Restoration Ecology Group in the Centre for Functional and Evolutionary Ecology in Montpellier, France, adds there are more than 1,000 species of tree that grow in desert areas.

“In many desert areas of the world there used to be enough trees to constitute to a real canopy – not in the sense of an English forest, where the forest is everywhere you look – [in deserts] they were restricted to areas where there was sufficient water.”

With so little forest in existence, conservation, on its own, would not be enough to preserve the trees, leaving restoration as the only option.

It’s a situation made more complicated by the global recession.

Some local agro-industries growing asparagus, grapes and oranges for foreign markets are laying off workers. With hard times on the way, Mr Whaley worries that what little vegetation remains may be used for firewood.

Whatever his project’s success, Mr Whaley is certain that the future of the tree rests firmly in the hands of the local people. They are encouraged to help with planting, and tree nurseries and seedbanks have been sent up in communities and schools.

“We are not going to Peru saying we are going to reforest the whole of the coast. We are developing a model that we can replicate and hopefully we can get that to be so interesting, or fun, or useful that it’s contagious.”

Hence the idea of an annual huarango festival, started in 2006 and held in April. The festival is a chance to celebrate the tree and the ecosystem it helps support. But it is also about food. The fruit of the tree can be used to make syrup, similar to molasses.

“Fill people’s tummies,” says Mr Whaley. “Where do you get social science and biodiversity overlapping? In the stomach. That is the best place to do it.”

The project has already had some successes, with a reserve set up in Tunga (see map, below), and more planned.

“We are at the beginning of habitat restoration – it’s only a science that’s been around for a couple of decades. Particularly in arid areas, we are only just learning how to do it.

“If I am able to come back in 500 years, then I would know if it has been a success. I will never know in my lifetime if its been a success.”

Key role of forests ‘may be lost’


Forests’ role as massive carbon sinks is “at risk of being lost entirely”, the BBC’s Mark Kinver has reported top forestry scientists as warning.

The International Union of Forest Research Organizations (IUFRO) says forests are under increasing degrees of stress as a result of climate change.

Forests could release vast amounts of carbon if temperatures rise 2.5C (4.5F) above pre-industrial levels, it adds.

The findings will be presented at the UN Forum on Forests, which begins on Monday in New York.

Compiled by 35 leading forestry scientists, the report provides what is described as the first global assessment of the ability of forests to adapt to climate change.

“We normally think of forests as putting the brakes on global warming,” observed Professor Risto Seppala from the Finnish Forest Research Institute, who chaired the report’s expert panel.

“But over the next few decades, damage induced by climate change could cause forests to release huge quantities of carbon and create a situation in which they do more to accelerate warming than to slow it down.”

The scientists hope that the report, called Adaption of Forests and People to Climate Change – A Global Assessment, will help inform climate negotiators.

The international climate debate has focused primarily on emissions from deforestation, but the researchers say their analysis shows that attention must also be paid to the impacts of climate change on forests.

While deforestation is responsible for about 20% of greenhouse gas emissions from human activities, forests currently absorb more carbon than they emit.

But the problem is that the balance could shift as the planet warms, the report concludes, and the sequestration service provided by the forest biomes “could be lost entirely if the Earth heats up by 2.5C or more”.

The assessment says higher temperatures – along with prolonged droughts, more pest invasions, and other environmental stresses – would trigger considerable forest destruction and degradation.

This could create a dangerous feedback loop, it adds, in which damage to forests from climate change would increase global carbon emissions that then exacerbate global warming.

The report’s key findings include:

  • Droughts are projected to become more intense and frequent in subtropical and southern temperate forests
  • Commercial timber plantations are set to become unviable in some areas, but more productive in others
  • Climate change could result in “deepening poverty, deteriorating public health, and social conflict” among African forest-dependent communities

The IUFRO assessment will be considered by delegates at the eighth session of the UN Forum on Forests, which has the objective of promoting the “management, conservation and sustainable development of all types of forest”.

Co-author Professor Andreas Fischlin from the Swiss Federal Institute of Technology commented: “Even if adaption measures are fully implemented, unmitigated climate change would – during the course of the current century – exceed the adaptive capacity of many forests.

“The fact remains that the only way to ensure that forests do not suffer unprecedented harm is to achieve large reductions in greenhouse gas emissions.”

Campaigners link tiger attacks to deforestation


The Sumatran tiger, a critically-endangered subspecies, is hanging on by a thread in its island home, reports Mongabay.com.

Biologists estimate that, at most, 500 individuals remain, with some estimates dropping as low as 250.

Despite the animal’s vulnerability, large-scale deforestation continues in its habitat mostly under the auspices of one of the world’s largest paper companies, Asian Pulp and Paper (APP).

Shrinking habitat and human encroachment has led to a rise in tragic tiger encounters, causing both human and feline mortalities.

While the connection between deforestation and tiger attacks has been put forth as a possible reason for the rise in attacks, a new study that looks at 12 years of tiger encounters confirms it.

Eyes on the Forest, a coalition of 25 environmental organizations, has mapped out encounters between humans and tigers, many of which ended tragically, and found that the majority took place adjacent to forested areas being cleared by APP.

In Riau Province, Sumatra, 55 people and 15 tigers have lost their lives due to the conflict. An additional 17 tigers have been captured and removed from their habitat.

The study found that 60% of the encounters (147 out of 245) between humans and tigers occurred in areas associated with expanded deforestation by APP and associated companies, under the umbrella of Sinar Mas Group (SMG).

Since 1985, Sumatra has lost half of its remaining forest. Worsening the situation for tigers is the continual decline of prey for the tigers due to heavy poaching by humans.

“With so much forest loss, the tigers have nowhere to go” said Ian Kosasih of WWF-Indonesia.

“In the last month alone, four tigers have been killed in Riau. There are fewer than 400 Sumatran tigers estimated to remain in the wild and every tiger killed is a significant loss to the population of this critically endangered subspecies.”

Since beginning operations in 1980, campaigners say the company has been responsible for more deforestation in Sumatra than any other corporation.

It is estimated that APP has pulped a total of 2.5 million acres.

Calls for the company to stop logging natural forests by Eyes on the Forest and other NGOs have so far fallen on deaf ears.

APP supplies Target and Unilever in the United States. Other corporations like Staples, Walmart, Home Depot, and the Australian company, Woolworths Limited, have all cut ties with the paper giant due to an increasingly troubling environmental record.

Trees: More than just carbon sinks


“In the absence of trees, our communities would simply collapse,” states Andrew Dokurugu, a project officer for Tree Aid tells BBC News.

Speaking from the charity’s West Africa offices in Burkina Faso, he explains how trees are vital for poor rural villages to survive in the long-term.

“We are looking at ways to promote sustainable agriculture and agroforestry,” he says.

“This will help ensure that the remaining trees are well looked after and that communities have access to the trees they require.”

Using the Family Trees and Land Use scheme in northern Ghana, one of Tree Aid-led projects that have helped 600,000 villagers, Mr Dokurgu outlines why so many communities in West Africa are facing tough times.

“Rural settlements located close to big cities have particularly difficult challenges,” he says.

“Urban developments damage the environment and remove trees for use in the cities.

“This quickly deprives rural areas of their sources of food, fuel and other tree products.”

Rising urban populations and expanding cities makes life tougher both inside and outside the city boundaries.

Tree Aid was set up in 1987 by a small group of foresters who were keen to use their expertise to help people in Africa, explained programme director Tony Hill.

“They saw that trees, potentially, were a way for poor rural families to help themselves in the long-term,” he told BBC News.

And in 1997, the charity established a permanent office in Ouagadougou, the capital of Burkina Faso.

Mr Hill described this development as a “step change” for Tree Aid, which has now planted more than 6.5 million trees.

“We were then able to work directly with local partners,” he said.

“Projects always have a beginning and an end, but the needs of the villagers do not end when the scheme finishes – particularly when you are dealing with trees.

“You need to have the continuity of attention, care and protection if you are going to deliver the benefits long-term.”

The need to plant and manage the region’s tree stocks is becoming increasingly important, Mr Hill says.

“If you go back several decades, the wild tree resources were rich enough for villagers to get more or less all of the products they needed without having to plant trees.

“Now, growing populations and an erratic climate means that villages have to invest in trees, rather than letting nature do its own thing.”

However, it is not simply the case of telling people to plant saplings and sitting back and waiting for them to grow.

Some cultures, Mr Hill reveals, have traditionally considered planting fruit trees as taboo: “People believed that if you planted a tree, you were bound to die before it bore fruit.”

But he says one of the biggest challenges is the issue of land tenure.

“For farmers, it is like a declaration of ownership. Planting trees says ‘this is my land and it is going to be mine for a long time.

“For many people, it is difficult to negotiate adequate secure tenure and get permission from all of the relevant authorities.”

This is one area where Tree Aid has been focusing its efforts, especially for women, who generally are not allowed to own land.

“In the drylands of Africa, where Tree Aid operates, the real value of trees is the products that they can take: fruits, leaves, bark and roots, firewood, building materials,” Mr Hill says.

He adds that healthy trees also help maintain the area’s ecosystems.

“People rely on trees to recycle nutrients, prevent erosion and maintain moderate water flows.

“Without trees in the landscape, you cannot have a sustainable farming system.

“Without farming, you do not have any life in these communities.”

UN: World’s forests facing tough tests


World forests face the dual challenge of climate change and the global economic crisis, a key UN report says.

On the BBC News website, environment reporter Mark Kinver said it suggested that although the economic slowdown might reduce deforestation rates in the short term, it was also likely to lead to other problems.

One concern, would be a lack of investment in the sector and in forestry management.

The study by the UN Food and Agriculture Organization (FAO) was published on Monday.

It is timed to coincide with the start of UN World Forest Week.

CTS Nair, one of the report’s lead authors and the FAO Forestry Department’s chief economist, said the economic crisis was having “tremendous impacts – both positive and negative”.

“You will find the forestry industries in a number of countries almost on the verge of collapse,” he told BBC News.

For example, he said the construction of starter homes in the US and Canada had fallen from about two million units at the end of 2005 to less than 500,000 now.

This had led to a dramatic fall in the demand for wood products, which was affecting forest-based industries and export markets in developing nations.

However, Mr Nair added, the downturn was having some beneficial effects.

“We are seeing a decline in the prices of soya beans, palm oil and rubber etc,” he explained.

“The prices have fallen drastically, so this means that the incentives for cultivating these crops have also gone down.

“As a result, the pressure to clear primary forest stands is also declining.”

The report, State of the World’s Forests 2009, also showed that the health of forests varied from region to region of the world.

“We see advances being made in places like Europe, but losses being made in places like Africa and especially developing countries,” Mr Nair observed.

“For example, what we see in the case of Africa is that there is a growing population yet the productivity within agriculture has remained extremely low.

“There is very little diversification in terms of sources of income so there is a very high dependency level on land use and natural resources, such as timber.”

“On the other hand, in places such as Asia where there has been rapid economic growth, people have moved out of agriculture to some extent and the pressure on the land has declined.”

In recent years, the importance of the world’s forests as carbon sinks has featured prominently in global climate policy discussions.

An initiative called Reducing Emissions from Deforestation and Degradation (Redd), which is likely to involve developed nations paying tropical forest-rich nations not to cut down trees, appears to be gaining support.

Mr Nair gave the scheme a cautious welcome: “In theory, it is an excellent idea but its implementation is going to be extremely tricky.

“If you look at the people involved in forest clearing, it is different people in different regions.

“For example, in Latin America, it is largely cattle rangers and soya bean planters. In South-East Asia, it is palm oil and rubber plantations.

“What we find is that it is not the smallholders, it is the big players who are working within a global market.

“So far, only the issue of what it is trying to achieve has been examined, the issue of how we are going to implement it has not really been discussed or examined.”

Brazil sees fall in deforestation rate


Deforestation in the Brazilian Amazon fell to 291 square miles (754 square kilometres) between November 2008 and January 2009, reports Mongabay.com.

This was a drop of 70% when compared to the same period 12 months earlier, said Brazil’s Environment Minister Carlos Minc.

A decrease in forest clearing had been expected.

Economic turmoil, which has reduced the availability of credit, and collapsing commodity prices (especially beef and soy) had undermined the main drivers of deforestation.

Mr Minc also credited government efforts, including increased vigilance and new loan policies, for the decline.

The data is based on Brazil’s Real-time Detection of Deforestation (DETER) system for tracking deforestation.

DETER is an alert system that updates IBAMA (Brazil’s environmental protection agency) with deforestation information, theoretically allowing authorities to attack illegal deforestation as it occurs.

However, the system requires on-the-ground follow up action, something that is difficult consider the poor land titling and political conflict between federal and regional authorities.

However, Brazil is developing an advanced satellite, which is called Amazon-1, that will use cloud-penetrating technology to allow more detailed monitoring of the Amazon.

Nearly 20% of the Brazilian Amazon, which accounts for about 60% of the world’s largest rainforest, has been destroyed since the early 1970s, but deforestation has slowed significantly since 2004.

Last year, the Brazilian government announced an ambitious plan to cut deforestation rates to 5,600 square kilometres (2150 sq mi) per year by 2014 in an effort to reduce carbon dioxide emissions.

Deforestation presently accounts for two-thirds of Brazil’s greenhouse gas emissions.

Forest fires ‘to add to climate concerns’


The fierce bushfires that scorched Australia’s Victoria State released millions of tonnes of carbon dioxide, a leading scientist has warned.

Forest fires could become a growing source of carbon pollution as the planet warms, he told Reuters news agency.

Mark Adams of the University of Sydney said global warming could trigger a vicious cycle in which forests could stop becoming sinks of CO2, further accelerating the rise of the planet-warming gas in the atmosphere.

“With increasing concerns about rising CO2, rising temperatures and reduced rainfall in many of the forested areas, then we could well see much greater emissions from forest fires,” added Professor Adams, dean of the Faculty of Agriculture, Food and Natural Resources.

The Victoria fires, which killed more than 200 people, were the worst in the nation’s history and many were still burning weeks later.

“Scientists worldwide are worried about fires and forests.

“It doesn’t matter if it’s the Arctic tundra fires, or peat fires in Kalimantan or bushfires in Australia,” observed the Australian researcher, who has worked in collaboration with the Bushfire Co-operative Research Centre.

In a submission to the United Nations last year, the Australian government said wildfires in 2003 released 190 million tonnes of CO2-equivalent, roughly a third of the nation’s total greenhouse gas emissions for the year.

Such large, one-off releases of CO2 and other greenhouse gases such as methane, are not presently accounted for in Australia’s annual list of national greenhouse gas emissions.

If they were, the country would vastly exceed its emission limits under the Kyoto Protocol, the United Nations’ main weapon to fight climate change.

This is one reason, critics say, why Australia is calling for amendments to UN rules on land use change, so that only human activities that “can be practicably influenced” are included.

Professor Adams said the UN climate summit at the end of the year in Denmark should discuss the growing threat from forest fires and how to develop better legal frameworks to tackle the problem.

In a study of how much carbon Australia’s forests and soil can store, he estimated that fires in 2003, which ravaged the capital Canberra, and in 2006-07 released about 550 million tonnes of CO2.

The current fires had already burned hundreds of thousands of hectares, he said, in areas with total carbon content of 200 tonnes per hectare or more.

Australia, though, was not his only concern; annual fires in Indonesia also release vast amounts of CO2.

Huge fires in 1997 released up to 6 billion tonnes of CO2, covering South-East Asia in a thick haze and causing a spike in global levels of the gas.

Research on the forest and peat fires by a team of international scientists found the blazes released the equivalent of up 40% of global annual emissions from burning fossil fuels.

Professor Adams described the findings as a “wake-up call”.

“When you see the step-increases (of CO2) that they observed, we have to sit up and take notice, that fires are a major problem,” he said.

In the past, he explained, native forest carbon had been in rough equilibrium over millions of years with fires, with very small accretion of carbon over very long periods of time.

“But then if you add rapid climate change and much greater fire frequency, the equilibrium carbon content of the native forests, instead of going up, is going to go down.”

Quarter of PNG’s rainforests ‘lost to logging’


Nearly one quarter of Papua New Guinea’s rainforests were damaged or destroyed between 1972 and 2002, Mongabay.com reports.

Researchers, writing in the journal Biotopica, said the results – published in a report last June – show that Papua New Guinea is losing forests at a much faster rate than previously believed.

Over the 30-year study period, 15% of the nation’s tropical forests were cleared and a further 8.8% were degraded through logging.

“Our analysis does not support the theory that PNG’s forests have escaped the rapid changes recorded in other tropical regions,” the authors wrote.

“We conclude that rapid and substantial forest change has occurred in Papua New Guinea.”

Deforestation and forest degradation in Papua New Guinea are primarily driven by logging, followed by clearing for subsistence agriculture.

Since 2002 (a period not covered in the study), reports suggest that conversion of forest for industrial agriculture, especially oil palm plantations, has increased.

The study is based on comparisons between a land-cover map from 1972 and a land-cover map created from nationwide high-resolution satellite imagery recorded in 2002.

The authors found that most deforestation occurred in commercially accessible forest, where forest loss ranged from 1.1 to 3.4% each year.

Overall deforestation was 0.8 to 1.8% per year, higher than reported by the UN Food and Agriculture Organization (FAO), but lower than the rate of deforestation on neighboring islands, including Borneo and Sumatra.

Papua New Guinea’s primary forest cover fell from 33.23 million hectares to 25.33 million hectares during the 30-year period.

In the same period, almost 93 million hectares of forest were degraded by logging.

Lead author Phil Shearman, director of the University of Papua New Guinea’s Remote Sensing Centre, said that without incentives to keep forest standing, Papua New Guinea would continue to lose its forests.

“Forests in Papua New Guinea are being logged repeatedly and wastefully with little regard for the environmental consequences and with at least the passive complicity of government authorities,” Dr Shearman said.

He noted that nearly half of the country’s 8.7 million hectares of forest accessible to mechanised logging have been allocated to the commercial logging industry.

But he added that there may be hope because Papua New Guinea had become a leader in the push by tropical nations to seek compensation from industrialised countries for conserving forests as a giant store of carbon.

The mechanism known as REDD (Reducing Emissions from Deforestation and Degradation) could potentially provide billions of dollars for conservation, sustainable development and poverty alleviation.

“The government could make a significant contribution to global efforts to combat climate change,” observed Dr Shearman.

“It is in its own interest to do so, as this nation is particularly susceptible to negative effects due to loss of the forest cover.”

UN studies have show that coastal communities in Papua New Guinea are particularly at risk from climate change.
