ABSTRACT
One of the most striking characteristics of irrigated agriculture in Spain is its enormous diversity, not only in terms of the usual structural variables such as farm size, plot distribution patterns, etc., but also in terms of geographical location (wet Spain and dry Spain) and crop type, hence the wide differences in climate conditions and available water resources. There are also considerable differences in unit water needs (measured in m3/ha) and water productivity, both across crop types and geographical areas, and major disparities in added value between irrigated and rain-fed agriculture, especially in central and southern Spain.
