- Abstract
- Irrigated agriculture remains the largest consumer of global freshwater resources, and improving water management in irrigated agriculture is a key issue to solve the global water and food crisis. For evaluating water management strategies in irrigated agriculture, the Water Use Efficiency (WUE) is often used as system performance indicator. WUE is largely controlled by the irrigation technology, and many large scale water conservation programs therefore promote the use of irrigation technologies that are associated with high WUEs. Yet, the WUE does only include technical and on site considerations related to irrigation, while socio-economic issues are neglected. WUE is therefore only a partial metric of the performance of a water management program. In this study, we aim to measure the impact of a water conservation program, in particular the conversion of surface to drip irrigation, in irrigated agriculture using a holistic measure of system performance, including technical and socio-economic system criteria. We aim to apply the new metric of system performance to the water conservation program for the Triffa's irrigated perimeter in East Morocco. The methodology encompasses different steps. The first step aims defining a holistic measure of system performance and compares this measure with the WUE as an actual system performance indicator. The holistic performance measure will be established in a "semi-participative" approach. A preliminary list of system performance indicators, encompassing technical, social and economic objectives is first established based on existing literature and other participative studies. The preliminary list is subsequently scored by a panel of stakeholders, and aggregated in an appropriate way. The second step aims implementing, for the selected case study, two water management scenarios: a reference status quo scenario, corresponding to the continuation of actual water management strategy, and an improved scenario, corresponding to the implementation of the envisaged water conservation management program. The third step aims implementing a system functional model, based on the hydrological balance, allowing to evaluate the aforementioned scenarios. The last step aims linking the established scenarios with the functional model to evaluate the impact of the projected water conservation program.
