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.

"ONE OF THE MAJOR HUMAN CHALLENGES IS TO PRODUCE ENOUGH FOOD FOR AN INCREASING POPULATION IN AN ENVIRONMENTALLY FRIENDLY WAY. THE SO CALLED �ECOLOGICAL INTENSIFICATION� RESPONDS TO THIS CHALLENGE AND CONSISTS IN TAKING PROFIT OF THE SERVICES OFFERED BY CERTAIN ORGANISMS WITH QUANTIFIABLE EFFECTS ON THE AGROECOSYSTEMS. THE PRESENT PROJECT IS FRAMED WITHIN THIS STRATEGY. OUR OBJECTIVE IS TO ASSESS THE INTERACTIONS BETWEEN THE MOST FREQUENT LIVESTOCK SPECIES IN THE DEHESAS (COWS AND PIGS) AND THE MOST COMMON OAK PESTS. THE DEHESA IS AN IBERIAN AGROECOSYSTEM WITH A HIGH ENVIRONMENTAL VALUE.
