Adaptive policy responses to water shortage mitigation in the arid regions--a systematic approach based on eDPSIR, DEMATEL, and MCDA.

摘要: Most of the arid and semi-arid regions are located in developing countries, while availability water adequate quantity quality is an essential condition to approach sustainable development. In this research, “enhanced Driving force-Pressure-State-Impact-Response (eDPSIR)” sustainability framework was applied deal with shortage Yazd, province Iran. Then, Decision Making Trial Evaluation Laboratory (DEMATEL) technique integrated into driven components eDPSIR, quantify inter-linkages among fundamental anthropogenic indicators (i.e. causes effects). The paper’s structure included: (1) identifying DPSIR along structuring eDPSIR causal networks, (2) using DEMATEL evaluate inter-relationships effects determining key indicators, (3) decomposing problem a system hierarchies, (4) employing analytic hierarchy process (AHP) weight each criterion, (5) applying complex proportional assessment Grey interval numbers (COPRAS-G) method obtain most conclusive adaptive policy response. systematic quantitative analysis revealed that root sources study area were weak enforcement law regulations, decline available freshwater resources for development, desertification consequences. According results, mitigating Yazd could be feasible by implementation such policy-responses as providing effective enforcement, updating standards social learning, boosting stakeholders’ collaboration.
