As international concern over tropical deforestation has grown over the last ten years, researchers have sought to understand the causes of deforestation and possible solutions using quantitative economic models. This book reviews the results and methodology of over 150 of these models and synthesizes the main lessons that can be learned from them. Higher agricultural prices, lower wages, less off-farm employment, and more roads generally lead to more deforestation. Major doubts remain on the impact of technological change, agricultural input prices, household incomes, and tenure security.

What policy lessons derive from the half-century of banana expansion in the coastal region? For that whole period bananas had a catalytic role in promoting coastal deforestation. At first, this was mostly through direct banana frontier expansion. Later the gradual settlement effects proved key. Modest credit subsidies, the large-scale construction and improvement of roads and ports, and a devalued exchange rate were probably the most important policies that contributed to the expansion of banana production, though they varied in importance during the different periods.

The United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UN-REDD) commissioned this report from the Center for International Forestry Research (CIFOR) to summarize the current state of negotiations towards a decision in Copenhagen, specifically outlining areas of consensus, options for resolving areas where consensus has not yet been reached, and priorities for research to support successful implementation of an international REDD Programme following a decision at the 15th Conference of the Parties (COP) in Copenhage

This paper presents the results of a preliminary survey of emerging demonstration and readiness activities to reducing emissions from deforestation and forest degradation and carbon stock enhancement (REDD+) across Africa, Asia, and Latin America. The survey was conducted between November and December 2008, and the information collected was updated until May 2009. While the results of the survey offer a useful snapshot of the landscape of REDD+ activities, they do not capture all the dynamics associated with this rapidly evolving field.

During the past 20 years, most settlements of the Brazilian Agrarian Reform (AR) have been established in or near better-preserved natural ecosystems, where environmental impact is likely to be negative and contribute to natural resources degradation. The objective of this work is providing a first, comprehensive insight of the impacts related to the environmental quality of these settlements, based on the primary survey of 4,340 AR settlements installed between 1985 and 2001. An index was calculated to integrate different aspects of environmental impacts in one single number.

The most prominent international responses to climate change focus on mitigation (reducing the accumulation of greenhouse gases) rather than adaptation (reducing the vulnerability of society and ecosystems). However, with climate change now inevitable, adaptation is gaining importance in the policy arena, and is an integral part of ongoing negotiations towards an international framework.

Fires are considered a potential threat to sustainable development for their direct impacts on ecosystems, their contribution to carbon emissions, and impacts on biodiversity. In 1997/98, Indonesia had the most severe fires worldwide, and smoke haze pollution recurs yearly. The fire-related policy problems are defined as smoke haze pollution, forest degradation and deforestation, and impacts on the rural sector. Some of the apparent major causes of the problems are identified. The estimate of area affected by fires in 1997/98 is revised from 9.7 million hectares to 11.7 million hectares.

This paper first provides a brief overview of what are and what represent forest ecosystem services. Then it considers the issues of price and valuation, and shows that valuation itself is not a solution but merely a tool. Considering then the reasons of the overall degradation of forest ecosystem services it shows that the main reasons tend to be fundamental: deforestation most often happens because it pays for local people - not so much because the institutionally created arrangements are perverse.

Popular concern about tropical deforestation largely drove the rapid growth in forestry assistance in recent years. Nevertheless, forestry assistance has had limited impact on forest clearing and much of it has gone to address other problems. To reduce inappropriate deforestation requires a combination of a multi-sectoral approach, greater regulation, and payment for environmental services. Aid officials have been partially unwilling and partially unable to adopt these approaches.

Short-term trends show that livestock production is becoming an increasingly important factor in regional development, possibly because of the combined effect of increasing the forages on offer and planting crops better adapted to the environmental and economic conditions of marginal areas and the decreasing interest of the State in expanding the agricultural frontier. Overall planning of land use should be improved, but to do so, a more detailed characterization and monitoring of deforestation are essential.

There is renewed interest in the use of native tree species in ecosystem restoration for their biodiversity benefits. Growing native tree species in production systems (e.g. plantation forests and subsistence agriculture) can also ensure landscape functionality and support for human livelihoods. Achieving these full benefits requires consideration of genetic aspects that are often neglected, such as suitability of germplasm to the site, quality and quantity of the genetic pool used and regeneration potential.
