They came to learn advanced satellite imaging techniques, and left at the end of September with maps that will help their countries manage their forests and take part in a potential global carbon credit trading system.

The pan-(bio)mass challenge

The WHRC is leading an effort to create the first pan-tropical biomass map that will demonstrate the future effects of deforestation and land use change across the globe. This information is key in developing the Reduced Emissions from Deforestation and Forest Degradation (REDD) policy initiative being negotiated under the United Nations Framework Convention on Climate Change (UNFCCC).

Under the REDD system, countries like the United States that emit a large amount of greenhouse gas could purchase carbon credits from countries like Gabon that have a lot of forest, but need cash to continue to protect it.

The system is also designed to encourage countries like Kenya to build up its forests, reversing the trend of deforestation that threatens to increase not only global carbon emissions, but also the ability of its citizens to grow food and find safe drinking water.

Using the maps, governments and tropical forest stakeholders will be able to monitor and track changes to land cover, helping inform policy decisions, said Joseph Kellndorfer, a WHRC scientist co-leading the pan-tropical mapping effort.

Tropical deforestation is estimated to be the cause of about 17 percent of man-made global carbon emissions, which makes it an easy target for combating climate change, said Dr. Kellndorfer.

“These maps give us a first estimate of what we’re talking about trading,” he said.

As the scholars taking part in the workshop indicated, deforestation is caused by a variety of factors. While logging is an obvious source, agricultural expansion—exacerbated by population pressures and a turn to the cultivation of cash crops—is also taking a major toll on tropical forests across Africa and Southeast Asia.

In Colombia, a decades-long guerilla war is having an impact even in remote forests; in Bolivia, hydroelectric projects threaten to flood the lush jungle of the Amazon basin.

The forest for the trees

Poverty is the number one barrier to forest conservation, said Edward Ssenyonjo, a remote sensing specialist with the Ugandan National Forest Authority. “More than 80 percent of people depend on the natural environment, mainly forests, to survive. This is compounded by a population growth [rate] of 3.2 percent,” he said.

His colleague, Abel Siample, of the Zambia Forestry Department, said that investment in alternatives to charcoal production and agricultural expansion are the only way to stop encroachment in protected forests.

Joint forest management committees in Zambia and India are giving disenfranchised people a say in how REDD funds are distributed, said Mukund Srivastava, of the Indian Forest Survey.

With a structure based on equality for women and the rural poor, these committees are developing a model so that a portion of REDD revenue returns to the community to attract tourism or sustainable industries and build up infrastructure.

People realize it when they hit the wall, and there is no more forest, but they cannot stop without alternatives. It’s a human dilemma: we do not change our behavior until it becomes too late.

-Nadine Laporte, associate scientist

However, said WHRC associate scientist Nadine Laporte, throwing money at the problem is not a sure way to protect diminishing forests. Sensitive to the socio-economic hardships that people in developing countries face, she is working with the scholars to find solutions to deforestation while meeting the needs of impoverished people.

“In Africa, deforestation is done by people who are trying to feed their families,” said Dr. Laporte, pointing out that people are driven to cut down the forest in a quest to find wood for cooking and heating.

Think global, act local

Although REDD was not adopted by the UNFCCC Conference of Parties that met in Copenhagen last December, Dr. Laporte said it is only a matter of time before a global carbon-trading system is in place.

Already, there are several bilateral agreements in place between developing nations and high carbon-emitting countries and states. Progress on REDD achieved in Copenhagen will continue at the next COP meeting in Cancun, Mexico, starting in late November.

Shifting the focus of international climate talks to helping communities and developing nations solve their own problems, the field survey sessions that Dr. Laporte and her colleagues take part in reach some of the most rural or forested areas in the world.

Community capacity-building is the name of the game for Peter Ndunda, a GIS specialist with the Kenyan Green Belt Movement (GBM), a non-governmental organization founded by Nobel Peace Prize winner Wangari Maathai.

By building up tree nurseries and embarking on a nationwide tree planting campaign, the GBM has been able to stem the trend of deforestation in part of Kenya. In addition, GBM offers civic and environmental education programs that help people understand how forests help retain soil and water, thereby supporting food production and safe drinking water.

A map of Kenya's forest cover shows the GBM's progress, but huge areas in the east remain deforested.

While GBM has made great strides in the last 20 years, the biomass map Mr. Ndunda created at WHRC shows how much further the country has to go.

Indeed, great swaths of Kenya were colored in brown on his map, indicating low forest cover; while the green areas where GBM is active nonetheless indicate that human activity has spilled over the boundaries of designated conservation areas.

“How do you help communities increase their yields without compromising future generations?” Mr. Ndunda asked.

With additional income from REDD, communities will have the time to wait for the trees to grow, while also improving their farmland, he said.

“REDD provides a great opportunity to help resolve the global challenge of poverty. This is a huge economic and ecological benefit that we cannot quantify.”

If you teach a man to map…

Some of the scholars taking part in the WHRC workshop were able to create a map of the forest cover as well as the biomass capacity of their country.

Using readily-downloadable data from free sources like Google Earth–as well as sophisticated software and the 160 processing systems owned by the WHRC– the scholars were able to create forest-cover maps of their entire country with a 15-meter resolution, and biomass maps with 500 meters resolution.

Another benefit offered through the WHRC program is the use of satellite radar imaging, a powerful tool that can penetrate the cloud cover that tends to persist over tropical forests, Dr. Kellndorfer said.

That way, forest managers will have more accurate “snapshots” of a forest region, without gaps in data due to cloud cover.

That was a difficulty for Edersson Cabrera, a remote sensing expert with the Colombian ministry of the environment. Though he has been collecting data on the country’s diverse range of forests for the past two decades, thick cloud cover in some years led to gaps in knowledge about how land use had changed over time.

Eric Armijo, of the Friends of Nature Foundation in Bolivia, said the maps he is working on with the WHRC will give his organization the tools it needs to make sure conservation policies are in place— and working.

“It’s a powerful way of pushing the decision-makers,” he said.

Tracy Johns in her office at the Woods Hole Research Center

It’s been a month after COP 15, the UN Climate Change conference that was supposed to give the world a new system for reducing carbon emissions.

A month to reflect, regroup, and respond to this reporter’s questions about what happened, and what didn’t, in Copenhagen.

From Woods Hole to Copenhagen

Tracy Johns is a research associate and policy advisor at the Woods Hole Research Center who focuses on the role of forests in stabilizing the world’s climate. She is an advisor to several countries on the Reduced Emissions from Deforestation and Forest Degredation (REDD) initiative, intended to create a carbon trading system that would adequately compensate countries that do not cut their remaining forests.

Having attended the last five COPs (Conference Of Parties), Ms. Johns said that the negotiations in Copenhagen, by comparison, were chaotic. Thousands of people from official delegations, NGO’s, and protest movements, crowded into a noisy meeting hall. It was difficult to find out where negotiations were taking place, even those related to REDD. When a delegation of African nations walked out of talks on carbon credits, she said, the conference really broke down.

With the REDD initiative dependent on the overall treaty, the process is stalled for now. Ms. Johns said she can sympathize with the African and developing nations, which are likely to feel the most deleterious effects of climate change, and yet are not responsible for the lion’s share of greenhouse gas emissions. However, she said, the stalled negotiations do not help anyone.

The Copenhagen Accord was eventually drafted by the US, China, Brazil, India, and South Africa, which other nations did not adopt. Because the UN Climate Change treaties must be adopted by consensus (remember the stalled Kyoto Protocol?) that means that there is no blueprint going forward. But, Ms. Johns said, there is still a lot that countries, especially the US, can do to reduce carbon emissions on a domestic level.

Seeing the forest for the trees

Rainforests have been dubbed the “lungs of the world” for their ability to “inhale” carbon dioxide (CO2) and “exhale” oxygen (O2), a well-known chemical exchange that sustains our every breath. In this way, trees are able to store or “sequester” large amounts of CO2, one of the critical greenhouse gases responsible for climate change.

But as trees are clear-cut for lumber or to make way for soybean plantations or cattle ranches, much of that carbon sequestered in trees is released back into the atmosphere. In addition, the trees are no longer able to inhale the atmospheric CO2 that is increasing in concentration each year. From Brazil to Gabon to Indonesia, deforestation is responsible for 12 to 18 percent of the world’s carbon emissions, said Ms. Johns.

“We will not be able to avoid the devastating effects of climate change without stopping deforestation,” she said. “Forests are a vital piece of the puzzle.”

In working out the jigsaw of economics versus the urgency of reducing greenhouse gas emissions, the REDD program aims to put a value on forests that are removing CO2 from the atmosphere every day, free of charge. Not only will this give developing nations a monetary incentive to protect their remaining forests, it will encourage consumers to make responsible choices, Ms. Johns said.

A fair trade?

While her focus is on the global carbon credit market, provisions in the Waxman-Markey bill– passed last June by the House of Representatives– allow companies to purchase carbon “0ffsets” for their emissions by contibuting to reforestation efforts or rainforest conservation, both in the US and abroad, Ms. Johns said. This initiative could make the US the largest carbon trading market in the world, she added, since the European Union does not allow REDD credits.

“As the legislative process moves forward, most of the bills being discussed include pretty strong pieces that wold allow a REDD to happen,” she said. “But the numbers President Obama has announced are far below our goals.”

In her work with some of the agricultural stakeholders in Brazil, for example, Ms. Johns has found that they would gladly find alternatives to cutting down the rainforest, but their practices reflect global demand for cheap beef and soybeans.

“One of the reasons why climate change legislation is important is that we’re not paying for the cost of pollution. If we understood the costs, it’s much cheaper to consume sustainably,” she pointed out.

“It’s got to be a collaborative effort between consumers and providers. Without a change in consumption practices, there will be no incentive to change.”

What can you do?

While forests in the US Northeast enjoy a fair amount of protection, Ms. Johns said people living here can have a part in reducing deforestation. She encourages us to do a little research to learn about the origins of products, and make an effort to support industries that use sustainable practices.

• One common sense tip in regard to forests would be to eliminate paper-based products like paper plates from your shopping list, and in the case of necessities like toilet paper, purchasing a post-consumer recycled brand.
