The general scientific objective of IRRIMED is the assessment of temporal and spatial variability of water consumption of irrigated agriculture under limited water resources condition. Measurements with sophisticated equipments are used to combine ground and satellite data into models, to ultimately produce simple and robust methods to assess evapo-transpiration (ETR) over large areas Two European institutions (IRD-cesbio, France ; WU, the Netherlands) associated with seven participants from four Mediterranean partner countries (Jordan, Morocco, Syria, Tunisia) have carried out the ambitious IRRIMED program through the following achievements: - For each test site (one per MPC) a GIS based collection of all available information on soil, water, land use, through processing high resolution satellite imagery, particularly short time paced time series -Performing micrometeorological measurements over fields representative of the main crops –in the 4 MPCs- while combining state of the art technology (eddy correlation and scintillometry) . Over most of the crop tested measured evapotranspiration was found significantly lower than estimated from the literature -Implementation and validation of a reference process model of water fluxes and vegetation growth used for benchmarking. Comparison and enhancement of robust and simple methods , applicable to satellite imagery (spatialized crop growth model SAFY) -Application of simple method to satellite imagery to derive ETR maps and thus water consumption by the irrigated fields as observed from space (SAMIR prototype). Further developments for regional assessment by coupling with weather forecast and Meteosat data. -Defining with the end-users through dedicated workshops and activities, their current needs and the specifications of a follow-up system for the operational implementation of the methods developed -Ensuring the sustainability of the approach: capacity building through 3 international workshops gathering all young scientists to be trained on the main scientific issues of the project. This has been materialised by 9 PhDs thesis defended on the project research topics -Wide dissemination of the results through a dedicated web site, with a querable publication data base, interactive illustrations, and on-line access to the workshop content and material. Following this success, the research will be pursued and applications developed, particularly within the PLEAIDeS project (FP6 GLOBAL4, 2006-2009).
