Two Sides of the Same Coin: A Theoretical Framework for Strong Sustainability in Marine Protected Areas

In 2014, the Italian Ministry of the Environment and Protection of the Territory and the Sea (MATTM) launched the "Environmental Accounting in the Marine Protected Areas" (EAMPA) project, which proposed a new accounting model for Marine Protected Areas (MPAs). The model foresaw the integration of ecological and economic components in classical accounting schemes through the quantification of stock and flows embracing both the perspectives. The project, which ended in 2019, allowed the testing and the realization of the multidisciplinary framework. Later, in the context of the EU Interreg "Integrated management of ecological networks through parks and marine areas" (GIREPAM) project, an upgraded version of the EAMPA framework was developed, including additional but fundamental components leading to a more detailed and complete assessment as well as a better theoretical definition. The definitive management framework is outlined through the creation of the two parallel paths, but it provides as a final result three balances from the strong sustainability perspective: ecocentric, anthropocentric and integrated. To ensure that sustainability is obtained, all the three balances must guarantee a positive net benefit for humans and nature alike.
