Research objectives and content
The proposed project consists of a land evaluation assessment in the Ebro delta using remote sensing techniques and geographic information systems. The objective of the research is to identify and quantify the main factors limiting rice production as well as, an integrated environmental study of the landuse management alternatives. First of all, special emphasis was made on multitemporal appraisal of remote sensing data. During 1994, 1995 and 1996 strong efforts were made to model rice crop growth and development, to evaluate the geobiophysical factors limiting the optimal yield, and to establish the soil-plant relationships and reflectance. During the return grant. the thematic mapping pattern spatial analysis together with the rice production modeling will specify a landuse management optimization. Finally a geographical information system of the study area with all the data collected will be developed, where the environmental variables and their interrelations will be evaluated.
