Land Degradation Indicators for Nile Delta: DPSIR Approach

摘要

DPSIR (Driving forces-Pressure-State-Impact-Response) framework is used to structure and classify information and to assist in the identification of the key set of indicators that best describe how farmers and other land users are managing their landand the impacts of this management. The DPSIR (LADA 2002) is a convenient representation of the linkages between the pressures exerted on the land by human activities, the change in quality of the resource, and attempts to release the pressure or to rehabilitate land that has been degraded. The interchanges among these form a continuous feedback mechanism that can be monitored and used for assessment of land degradation indicators. Following indicators were assisted for the Nile Delta of Egypt. Drivingforce indicators: population growth, poverty, land resources stress, water stress and sea level rise. Pressure indicators: sea-water intrusion, urban encroachment, soil scrapping and water quality. State indicators: shoreline erosion, salt affected soil,waterlogged soil and soil and water pollution. Impact indicators: land productivity decline. Response indicators: legislations (Law 1983, 1985. Law 4 1994), land improvement and conservation, shoreline protection, investment in land and water resources,second national drainage project (2001-2007), Commitment to International Convention.
