The proposed intervention is part of a complex project, Maristanis, funded by the Mava Foundation and coordinated by the MEDSEA Foundation. Maristanis developed activities regarding governance, water quality and saving, restoration (sea and land-based) and agriculture and fishing involvement. In the governance framework, the project focussed on creating an integrated management model offering a long-term management strategy for the coastal wetlands found in the Gulf of Oristano – a new regional park. It contributed to balancing social and environmental needs and paved the way to recognise the economic and cultural potential of the wetlands. As the implementation of the intervention was still underway, a self-assessment using the IUCN Global Standard for Nature-based Solutionsᵀᴹ was carried out. It was used to identify entry points to strengthen the intervention under the umbrella of Nature-based Solutions.
