Application of Data Envelopment Analysis to Evaluate Investments in the Modernization of Collective Management Irrigation Systems in Valencia (Spain)

“…As indicated above, few studies use a methodology similar to that used in this study to measure efficiency. While other studies highlight the improvement in water-use efficiency achieved by installing DI (Ali et al 2020), they point to other factors that limit efficiency. For example, the training of farmers and technicians in the WUAs, the size of the farms or the proper management and organization of the irrigation procedures (Pereira and Marques 2017;Ali et al 2020;Cao et al 2020, Gautam et al 2020).…”

These factors could also explain the differences in efficiency between WUAs with similar characteristics in this study.…”

Potential for land and water management adaptations in Mediterranean croplands under climate change

“…In Egypt, where tangible drip irrigation potentials showed an even higher spatial match of 73%, adoption rates are on the contrary very low (7% of irrigated area utilizes drip) (Jägermeyr et al, 2015). Positive forecasts across the country have placed emphasis on policy restrictions on flood irrigation, increased presence of extension agents, and knowledge exchange following the practice's demonstrable returns on investment (Ali et al, 2020;Mourshed, 1996). Similarly, the considerable, yet as-of-yet unrealized, potential for conservation agriculture in either country may be able to draw on lessons from Syria, Jordan, and Iraqregions where the practice has successfully been implemented and where the presence of similar rain-fed and irrigated systems can provide a blueprint for further implementation and scaling (Loss et al, 2015).…”

Sustainable Groundwater Management Through Micro Irrigation: A Critical Review on Challenges and Solutions

“…The drip irrigation system estimated tomato growing's economic efficiency using financial discounted criteria and data envelopment analysis. Compared to non-drip irrigation, drip irrigation investment increased net return per hectare by 67 % and benefit-cost was 1.35 (Ali et al, 2020).…”
