Site degradation occurs mainly through deterioration of the soil's capacity to capture and store water, as well as the loss of organic matter or the accumulation of salts or other toxic substances in the soil. This degradation process, leading to the reduction of the biotic potential of the site, is known as desertification. In this study, changes in bulk density, organic matter, and electrical conductivity are used as indicators of desertification in northeast Mexico.

Community based forestry has the potential to contribute much more to achieving sustainable development and poverty reduction than is the case today. This paper describes and analyzes these potentials and demonstrates their feasibility with real world cases of community forest businesses and innovative policies and business partnerships.
