The general objective of this project is to develop a comprehensive method for the study of the water use and the resistance to the drought of the natural and irrigated vegetation in north eastern coastal zone of Egypt, by means of a combined historical and current space-based remote sensing database, vegetation models and field measurements. A retrospective study of east Mediterranean Basin at the regional level, using NOAA – AVHRR, (5 km) data from 1981 to present. The using of such data will lead to improve water management practices in the coastal area for environment-friend and sustainable development as well as contributing to the design of a global information system for better management of water resources in the coastal area.
