Desertification is defined by the United Nations Convention to Combat Desertification and also by the present project as land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities. In order to obtain information for policy design, implementation and analysis, in order to put into effect the International Convention Against Desertification, it is essential to understand cause-effect relations linking desertification with socio-economic issues and agree upon methodologies for the elaboration of impact indicators that will meet the specific requirements of policy making. In other words, the formulation of a methodology to assess and monitor developments in relation to desertification is a key step in combating the phenomenon. The core challenge is to help policy makers to use indicators and to build a greater capacity to analyse, summarise and propose creative solutions. This is the only way that indicators can help to combat desertification and improve the quality of people's lives in the affected areas. Progress made thus far by most countries has tended to focus on physical and biological indicators. Social processes are universally acknowledged to be important but very few studies have ventured to place numerical values on these processes and still fewer have attempted to link them with other environmental indicators.This pilot project proposes to develop and validate indicators of the social and economic processes associated with desertification
