Paying for Biodiversity Conservation Services in Agricultural LandscapesbackgroundThis document describes the genesis for the World Bank GEF project from 2002-2007 to implement payments for ecosystem services for silvo-pastoral systems in Colombia, Nicaragua, and Costa Rica. The payments were designed to compensate for biodiversity services: international donor money would be exchanged for the international environmental service of biodiversity.

Management of sedimentation in tropical watershedsBackgroundThe sedimentation of reservoirs is a serious problem throughout the tropics, yet most attempts to control sedimentation in large river basins have not been very successful. Reliable information on erosion rates and sources of sediments has been lacking. This paper discusses some of the limitations in estimating erosion and sedimentation and encourages development of specific sediment budgets in order to extrapolate equations and generate management procedures.

One Century of Forest Rehabilitation in the Philippines: Approaches, Outcomes, and LessonsbackgroundThis chapter provides a review of reforestation efforts in the Philippines, beginning with small-scale forest rehabilitation efforts since 1910. Reforestation was traditionally implemented by government and private companies. Since the mid-1970s, international funders have driven these efforts. Open access copy available |
Effect of Vegetation Restoration on Soil and Water Erosion and Nutrient Losses of a Severely Eroded Clayey Plinthudult in Southeastern ChinaBackgroundIn this study, researchers compare erosion from reforested and degraded sites in subtropical southeastern China. Goals & MethodsThe objective of the study was to estimate the long-term influences of reforestation on soil and water erosion and nutrient losses in regions of southeast China that are characterized by severely eroded bare land derived from Quaternary red clay. The study examined surface runoff, soil erosion, and soil nutrient content. Available with subscription or purchase |
Deforestation and Reforestation of Latin America and the Caribbean (2001–2010)backgroundThis study examines contrasting forest cover change dynamics in Latin America and the Caribbean using MODIS satellite imagery. Many studies have documented deforestation, while others report forest recovery. This study seeks to analyze these trends on a large scale and connect them to environmental and population variables.

Special Report of Captain George P. Ahern, Ninth U.S. Infantry, in Charge of Forestry Bureau, Philippine Islands, Covering the Period from April, 1900, to July 30,1901backgroundThis 139-page report outlines the state of the Spanish colonial Forestry Bureau at time of arrival of US forces in the Philippines (~1900), and reforms instituted by Captain Ahern. He describes the timber business in the Philippines including the state of the forested lands, species exploited, and volumes exported. At that time, 160 species of native trees were exported, but the Forestry Bureau knew of 665 native tree species. Ahern suggests trying to find a use for them to make timber extraction more profitable. Samples of 100 species were sent to the US for exhibition. Open access copy available |
