Document Summary
Decision to manage a landscape means you"ll decide who the winners and losers are in terms of species living in that landscape. Depends on which species you decide will get extracted from the forest. How tropical forests differ from temperate forests and why that matters. 8% of earth"s land surface supporting >> 50% species. Governance problems (e. g. , corruption, lack of expertise) About half of the world"s tropical forests have been destroyed or severely degraded. Tropical paradox: rich forests on poor soils. Most of the nutrients held in the vegetation, not in the soil. Changing drivers of tropical deforestation (rudel, land use policy, 2007) Meta-analysis of 268 case studies (1970-2000) to determine correlates of. 1980s: best correlates of deforestation were colonization programs, roads. 1990s: best correlates of deforestation were ranching, road building. 1980s: smallholder agriculture, poor export economy for agricultural. Government-sponsored land reform and redistribution schemes lots of small-scale settlements (slash and burn agriculture) Roads, land tenure provided by the government.
