A Model to Support Sustainable Resource Management in the “Etna River Valleys” Biosphere Reserve: The Dominance-Based Rough Set Approach

Abstract

For several decades, studies and conventions have highlighted the importance of the ecosystem services provided by natural resources and biodiversity for humanity and the need to move their management towards a sustainable model. Inthe United Nations 2030 Agenda for Sustainable Development (2015), among its 17 Sustainable Development Goals (SDGs), there isalsoSDG 15, “Life on Land”, specifically dedicated to biodiversity, forests and desertification. The aim is to “sustainably manage forests, combat desertification, halt and reverse land degradation, and halt the loss of bio-diversity”. The UNESCO “MAB—Man and Biosphere” Programme could achieve this goal by establishing Biosphere Reserves (BRs). Among them, the establishment of the BR “Etna river valleys” is an opportunity to adopt sustainable development models in the “Etna Park system” (UNESCO site since 2013) for the regeneration of virtuous relationships between cities and rural areas and the promotion of the conservation of natural resources and biodiversity through strategies of territorial enhancement with a multifunctional vision of agriculture and territory. This research aims to provide, through the methodology of “Rough Sets”, a useful tool to support the strategic choices that stakeholders will be called upon to make for the management of the complex environmental, cultural and economic mosaic that characterises the BR “Etna river valleys”.The results show both weaknesses and strengths in the transition towards a sustainable land management model, which will nonethelesshave to be supported and accompanied by information and financial support.
