Abstract:
Gridded fields of changes in runoff and river flow (discharge) due to historical and hypothetical deforestation from Douglas et al. (2005). Scenario 1 (Sc1, historical) compared distributed runoff (RO) and river flow (discharge, Q) generated from pre-industrial land cover (based on WWF Terrestrial Ecoregions of the World (Olson et al., 2001) with runoff and river flow derived from contemporary landcover. Scenario 2 (Sc2, hypothetical future) compared distributed runoff and river flow (discharge, Q) generated from the contemporary landcover with runoff and river flow generated from a hypothetical future forest conversion scenario. The contemporary landcover was developed by combining the Global Land Cover Characteristics Database (GLCCD 2000; Loveland et al. 2000) interpreted using the International Geosphere-Biosphere Programme (IGBP) land cover classification scheme (IGBP 1998) with cropland and cropland mosaic classes from the IFPRI Agricultural Extent database, which is a reinterpretation of the GLCCD v2.0 dataset. This exercise identified areas, at a 1km resolution, that contain 30 percent or more agricultural activity. For details on the creation of the IFPRI Agricultural Extent, see Wood et al. (2000) and IFPRI (2002). The Center for Sustainability and the Global Environment at the University of Wisconsin has developed a global pasture surface based also on a reinterpretation of the GLCCD v2.0 data. The pasture surface represents non-forest areas that are used for grazing (Ramankutty 2003). The agricultural extent and pasture surfaces were superimposed on the IGBP classified GLCCD to create the contemporary land cover surface. The objective Scenario 2 (hypothetical future forest conversion), was to design a hypothetical, "worst case" land cover change experiment that explored deforestation in the most vulnerable tracts of remaining forest, and to measure what effect this conversion could potentially have on biodiversity, hydrological function and ultimately, on downstream human populations. The baseline for this scenario was the contemporary land cover surface because the contemporary land cover surface was our best available representation of existing land cover. In Scenario 2, only existing forest area (circa 1992/3) within the tropical forest biomes was targeted for conversion; land cover in all remaining portions of the domain was held constant. The global conservation status from the WWF terrestrial ecoregions database (Olson et al., 2001) was used to identify the areas most vulnerable to change within the tropical forest biomes; forest conversion was limited to areas. The conservation status is an indicator of the degree and threat of change for each individual ecosystem. The key factors defining the conservation status are the degree of habitat loss, the level of fragmentation, remaining block size and level of conversion. The areas classified as critical or endangered were designated as those most threatened in terms of potential deforestation. Areas currently under protection, as identified by The World Conservation Monitoring Centre's (UNEP-WCMC, 2003) protected areas database, were therefore not subject to conversion. The sceanrios are defined as: Scenario 1: Change in runoff (del RO, in mm/yr) due to historical forest conversion to agriculture: Douglas et al. (2005) Scenario 1: Change in discharge (del Q, in km3/yr) due to historical forest conversion to agriculture: Douglas et al. (2005) Scenario 1: Relative change in discharge (ratio of del Q to Q) due to historical forest conversion to agriculture: Douglas et al. (2005) Scenario 2: Change in runoff (del RO, in mm/yr) due to hypothetical future forest conversion to agriculture: Douglas et al. (2005) Scenario 2: Change in discharge (del Q, in km3/yr) due to hypothetical future forest conversion to agriculture: Douglas et al. (2005) Scenario 2: Relative change in discharge (ratio of del Q to Q) due to hypothetical future forest conversion to agriculture: Douglas et al. (2005)
