Application of multi-criteria analysis selecting the most effective climate change adaptation measures and investments in the Italian context

In the context of climate change, one of the EU's major political efforts focus on water management. Public investment is carried out considering several drivers, from economic development to demographics, climate, and pollutants. Meanwhile, the need for evaluation methods is also increasing, so their development has grown in recent years. Among these, Multi-Criteria Analysis methodologies (MCA) have taken on great importance. This work aims to demonstrate the usefulness of MCA in addressing crucial environmental issues, such as the use of water resources for agricultural and food production. The document presents an application of MCA for the ranking and selection of projects to be financed under the Italian National Plan on Water Resources. The Plan is part of the national initiatives planned for the adaptation of the agricultural sector to climate change. The selection criteria have been identified following a participatory approach, and to respond to both the challenge of climate change and the limited availability of funds. MCA is used to select the best projects to be financed with the available amount. The Italian experience confirms the effectiveness of MCA and highlights how the involvement of both decision makers and stakeholders is necessary for a successful application of MCA to environmental issues.
