EFFICIENT AGRICULTURE WATER USE IS OF CRUCIAL IMPORTANCE FOR WATER RESOURCES MANAGEMENT. CONSEQUENTLY, ACCURATELY DETERMINING EVAPOTRANSPIRATION (ET) IS THE FIRST STEP FOR IMPROVING IRRIGATION EFFICIENCY AND PRODUCTIVITY AND FOR QUANTIFYING THE ECOSYSTEM WATER BALANCE. SEVERAL APPROACHES FOR DETERMINING ET HAVE BEEN PROPOSED IN LITERATURE, BUT THE RELATION BETWEEN HIGH AND LOW SPATIAL RESOLUTION METHODS STILL REMAINS UNRESOLVED IN IRRIGATION STUDIES AND WATER MANAGEMENT PLANNING.

"IT IS OF STRATEGIC IMPORTANCE FOR MEDITERRANEAN AGRICULTURE TO DEVELOP NEW VARIETIES OF DURUM WHEAT WITH GREATER PRODUCTION POTENTIAL, TOGETHER WITH A BETTER ADAPTATION TO ADVERSE ENVIRONMENTAL CONDITIONS AND BETTER QUALITY OF GRAIN. WHILE THAT HARD WHEAT IT HAS BENEFITED AS OTHER CEREALS OF THE GREEN REVOLUTION, GENETIC PROGRESS IN RECENT DECADES HAS BEEN LESS EVIDENT, PARTLY MASKED BY CLIMATE CHANGE, AND THE UNDERLYING MECHANISMS ARE NOT WELL KNOWN.
