Sustainability assessment using geostatistical analysis and spatial modeling in El-Tina plain in Egypt.

摘要: Sustainable Land Management (SLM) in agriculture is a very complex and challenging concept encompassing biophysical, socioeconomic environmental concerns that must be viewed an integrated manner. In order to evaluate the sustainability of sector i n El-Tina plain, Egypt, Ordinary Kriging (OK), spatial modeling were used generate soil map build SLM model ArcGIS for assessment on basi s international Framework Evaluating (FESLM). Five FESLM pillars: enhance production services (productivity), reduce l evel risk (security), protect potential natural resources prevent degradation water quality (protection), economically viable (v iability) acceptable (acceptability) assessed under t he umbrella biophysical socio-economic conditions. These indicators have been included prototype decisi support system (DSS). Feedback was obtained from farmers after DSS their farming system. Information extract ed 58 questionnaires carried out with local aimed characterize land management systems, outli ne constraints potentials, 96 sample points nd 41 observation analyzed accordi ng methodology develop address five pillars FESLM, producing maps showing mapping units sustainability, biophysi cal, social economic As result, his able highlight these are most need assistance achieve sustainabili ty. It will also valuable tool evaluation monitoring stra tegies sustainability. Major con straints could identified as high salinity, alkalinity la ck infrastructure. Based nalysis, soils study area belong classes 2, 3 4.
