This thematic area focuses on the conservation, restoration and sustainable management of mountain ecosystems and natural resources. MountMed works on biodiversity, water, soil, forests, renewable energy, circular economy and climate resilience. These issues are critical for mountain territories, where environmental pressures are closely linked to livelihoods, productive systems, quality of life and long-term territorial viability.

Its fields of action include decentralised renewable energy systems, circular economy practices, sustainable land use, water resource management and the protection and restoration of mountain systems for socio-ecological resilience. Through this area, MountMed supports actions that connect environmental protection with community well-being, productive renewal and long-term territorial sustainability.
