One of the advantages of spatial information systems is that it is still evolving with new frontiers. In addition to mapping, predictive modeling, this research will use two of the new frontiers: participatory GIS and multi-criteria analysis in addressing water issues and food security in MENA countries. The issues cannot be solved by potential water resource mapping, introducing new seed varieties or importing foods. Community participation in planning at village level is essential. Participatory GIS (PPGIS) developed in recent years allow application of GIS at community level with the input from farmers. In addition, their expert opinion can be incorporated into GIS for prioritizing and ranking objectives using multi-criteria analysis. The project will utilize all the benefits from recent advancements of spatial information techniques to generate information for addressing water and food security issues in the MENA and in particular Qatar region.
