Adaptive strategies of on-farm water management under water supply constraints in south-eastern Spain

The study analyses the effect of irrigation water constraints on-farm management in the Campo de Cartagena Irrigation District (south-eastern Spain), which is characterised by a semi-arid climate with a marked structural water deficit. The methodology applied was the comparative assessment of management indicators during two periods with very differing water availability. A set of performance indicators was selected and calculated to assess the effects on on-farm water management and productivity.
