The aim of this work is to evaluate the sustainability of water management for agriculture in a specific territory through the creation of a synthetic index resulting from the aggregation of multiple indices (environmental, economic, and social). The resulting synthetic index can be used to set sustainability standards and to guide the choices mandated by the Common Agricultural Policy 2023–2027. In this work we intend to show how the Multiple Criteria Decision Analysis (MCDA) method facilitates a complex process such as establishing a degree of sustainability in a certain area and, therefore, provides support to national or regional policies and communities. The integration of MCDA and GIS increases the efficiency of the support activity. A case study is presented evaluating the level of sustainability in the Irrigation and Reclamation Consortium of Piacenza and Emilia Centrale, in the Emilia Romagna region.

Wetlands have a fundamental role in the maintenance and development of the global ecosystem and human health. Assessing the value of Ecosystem Services (ES) that wetlands provide is strictly related to environmental, economic, and social sustainability. This paper considers the Oristanese Reclamation District located in the Italian region of Sardinia, where the highest amount of water resources is used for irrigation. Moreover, the study area is characterized by the presence of numerous ponds and wetlands that are deeply interconnected with local agriculture, attracting a substantial number of tourists. This paper aims to evaluate the touristic value in the area by applying the travel cost method, a non-market evaluation method used to derive consumers’ preferences. Through secondary data, we obtained a total estimate of economic benefits from the recreational uses of the site of approximately €1.25 Mln/year. The results provide support to decision-makers for improving management options while ensuring a tradeoff between the economic benefits derived from tourist activities and the conservation of the wetland area.

Irrigation plays a pivotal role in Southern Europe, and its importance is expected to further increase due to rising climatic variability. Concurrently, the European Water Framework Directive (WFD) mandates the safeguarding of water bodies and the implementation of incentive pricing strategies to promote efficient water management. Within this context, Irrigation Scheduling Decision Support Systems (IS-DSS) could contribute to the achievement of these objectives, although there are still obstacles to their adoption due to uncertainties regarding their potential benefits. This paper aims to derive a pricing model that reflects actual water use through the adoption of an IS-DSS. The innovation of this study lies in showing that adopting an IS-DSS to reduce irrigation volumes can potentially lower concession fees in collective irrigation systems. Thus, it contributes to the fulfilment of the WFD’s objectives regarding incentive water pricing. Notably, the tool is evaluated using the case study of a farm located in the Mediterranean region. The results demonstrate the dual benefits of IS-DSS adoption: on the one hand, it helps preserve water resources with a 24% reduction in irrigation volumes; on the other, it decreases irrigation costs by 20% at the farm level and by 9.4% at the irrigation district level. Therefore, the presented study provides insights into the potential of IS-DSS to enhance water pricing policies to promote efficient water management in Southern European agriculture in alignment with the WFD requirements.
