Behind the headlines about the loss of tropical forests in Latin America lies a complex and fascinating story of the social pressures which cause it. Trees, People and Power looks at the various groups, interests and conflicts involved, and explores the repercussions for forestry, the environment and the livelihoods of the rural and urban poor. Until the social and political dimensions of deforestation and forest protection schemes are understood, measures to prevent or slow deforestation are likely to involve technical interventions which will prove ineffective in the long run, and may well result in further impoverishment and environmental degradation. Peter Utting takes a critical look at the experience of forest protection and tree planting in a number of countries and considers how social and political factors affect the feasability of such schemes. Many environmental projects and programmes have failed to balance concerns for the environment with those of human welfare. Until they do, it is unrealistic to expect any significant progress towards sustainable development. Peter Utting is a senior researcher coordinator with the United Nations Research Institute for Social Development. He is the author of Economic Adjustment under the Sandinistas (UNRISD, 1991) and Economic Reform and Third World Socialism (Macmillan, 1992). Originally published in 1993
Costa Rica was once one of the most deforested countries in the world. Today it is a pioneer in reforestation, forest management, and forest protection policies. The report describes the evolution of these policies since the 1950s, focusing on internal and external influences, particularly those of the World Bank. This case study is one of six evaluations of the implementation of the World Bank's 1991 Forest Strategy
Roger C. Dahlman Environmental Sciences Division U.S. Department of Energy Washington, D.C. The potential for humans to alter Earth's atmosphere has been recognized since the end of the 19th century when Arrhenius estimated that a doubling of atmospheric carbon dioxide could alter the atmospheric radiation balance and raise average global temperature. Today, atmospheric CO concentrations play an important part in the 2 climate-change debate. Sources and sinks of CO associated with land use can be 2 significant determinants of the rate and magnitude of atmospheric CO change. 2 Combustion of fossil fuels and the deforestation associated with land-use change both contribute CO to the atmosphere; in contrast, biological processes on land create 2 potential sinks for the excess CO . Thus, land-use change and associated biological 2 processes become important elements in assessments of future atmospheric CO 2 increase; land-cover properties also affect the Earth's albedo, which is a climate feedback.
"Although private forest use in Brazil has been regulated at least since the Forest Code of 1965, cumulative deforestation in the Brazilian Amazon reached 653,000 km2 by 2003 (INPE 2004). Much of this deforestation is illegal. In 1999, the State Foundation of the Environment (FEMA) in Mato Grosso introduced an innovative licensing and enforcement system to increase compliance with land use regulations. If successful, the program would deter deforestation that contravenes those regulations, including deforestation of riverine and hillside forest (permanent preservation areas), and reduction of a property's forest cover below a specified limit (the legal forest reserve requirement). This study seeks to assess whether introduction of the program affected landholder behavior in the desired direction. Simple before/after comparisons are not suitable for this purpose, because there is considerable year to year variation in deforestation due to climatic and economic conditions. Nor is it valid to assess program impacts by comparing licensed and unlicensed landholders, even though the program focused its enforcement efforts on the former. This is because, first, landholders with no intention of deforesting may choose to become licensed; and second, unlicensed landholders may be deterred from deforestation by the mere existence of a serious program that aims for universal licensing. To meet these challenges, the study applies a difference-in-difference approach to geographically explicit data. It looks for, and confirms, post-program declines in deforestation in high-priority enforcement areas relative to other areas; in more easily observed areas relative to less easily observed areas; and in areas of low remaining forest cover (where further deforestation is probably illegal) relative to high remaining forest cover. Thus, even against a backdrop of higher aggregate deforestation (driven in part by higher agricultural prices), there is evidence that the program in its early stages (before 2002) did shift landholder behavior in a direction consistent with reduced illegal deforestation. (The legality of deforestation was not however directly observed). The study hypothesizes that this behavioral change resulted from an initial perception of increased likelihood of the detection and prosecution of illegal deforestation, following announcement of the program. The study does not assess Mato Grosso's new system for environmental regulation (SLAPR) impacts following the change of state administration in 2003. "--World Bank web site.
