摘要：In the last decade, groundwater demand has been quickly increasing, and overexploitation has been already recognized in many regions. In this research a case study where the groundwater resource is used for the irrigation is analyzed. The study shows a common case in the cost line of the Mediterranean regions (Apulia region, Italy), for which salt incursion from see is largely quoted. An integrated model with hydrologic, agronomic and economic themes has been built to perform farmer’s behaviors under three different water policy designs. Namely, status quo scenario where groundwater is subjected to competitive and free access use and, two different groundwater allotments restrictions, has been analyzed. Taking into account discounted farmer’s net value, findings here show as competitive use is not the most convenient groundwater management. Reduction in groundwater exploitation rate implemented with all the other scenarios show a more profitable use of this resource over time.
