Integrated assessment of policy interventions for promoting sustainable irrigation in semi-arid environments: a hydro-economic modeling approach
The paper presents a hydro-economic model linking farm-based economics with hydrologic simulation to evaluate sustainable irrigation in Spain's Middle Guadiana basin. It finds that current excessive water use threatens the European Water Framework Directive's goal of 'good ecological status' by 2015, particularly during summer low-flow periods. While the Guadiana River Basin Management Plan may improve water productivity, it may not fully ensure required environmental flows, and securing these flows would likely reduce the viability of upstream small-scale rice farms.
