Integrating expert knowledge in GIS to locate biophysical potential for water harvesting: methodology and a case study for Syria

In Syria water harvesting is not much adopted by farmers. One of the reasons is that the agricultural research and extension support services in Syria lack specific and systematic knowledge on potential areas and suitable locations for water harvesting. The objective of this study is to provide a rapid GIS-based analytical technique to assess suitability for various water harvesting systems in Syria, with the ultimate objective to adapt the technique for use at the level of the CWANA region.
