To date in idsb02: interactions between environment and development, historical/ archaeological/ anthropological context, contemporary international development discourse, fundamental principle of environmental science. Between the tropical rainforest zone and the great deserts. In northern hemisphere summer is semi arid wet season and winter is the dry season under the. Defined by very low precipitation (<1000mm per year) Occupy ~41% of the global terrestrial area. One of the worlds most heavily inhabited ecosystems. Dryland are a large and important region, particularly in sub-sahran africa. Livelihoods dominated by environmental constraints: low water availability/ water cycles, limited availability of soil nutrients, soil erosion. Highly developed, context specific, local bodies of environmental knowledge are needed to manage appropriately. Proximate causes of land degradation in semi-arid environments. Ultimate causes of land degradation in semi-arid environments. Any combination of environmental, social, economic and political factors resulting in increasing sedentarization on lands not suited for it (environment limits of growth), as well as:
