Climate change poses significant challenges to water management in mountain regions, particularly in the Alps and pre-Alps, where small, isolated communities rely on limited resources for energy and water. This study explores the feasibility of implementing micro-hydroelectric systems in these areas, focusing on small streams with no fish populations, as a sustainable solution for energy production without compromising ecological integrity. In many Alpine communities, such as the one described in this case study, small streams remain underutilized. These streams, often devoid of fish due to natural or anthropogenic factors, present an opportunity for decentralized energy production through micro-hydroelectric plants. By strategically placing small-scale hydroelectric systems along these streams, local families can generate renewable energy to meet local needs while minimizing environmental impact. To ensure ecological sustainability, this study proposes specific technical limitations for such installations: installed power <20 kW, water flow <50 liters/second, and a maximum height difference (head) of <50 meters. These constraints are designed to prevent overexploitation of water resources and protect local ecosystems. A cooperative or associative approach is proposed for the units/families involved along the watercourse. This model encourages collaboration among local stakeholders, ensuring equitable distribution of benefits and shared responsibility for maintenance and environmental stewardship. Such an approach not only fosters community engagement but also enhances the long-term viability of the project. This proposal highlights the socio-ecological-technological (SET) framework necessary for such projects, emphasizing the integration of local knowledge, ecological conservation, and innovative technology. The aim is to foster international dialogue on overcoming legal barriers and promoting sustainable water management practices in mountain regions globally. The findings suggest that micro-hydroelectric systems, when carefully designed and implemented within the proposed technical limits and through a cooperative approach, can provide a viable energy solution for small Alpine communities, contributing to climate resilience and sustainable development. This abstract invites further discussion on the potential for scaling such projects within the broader context of mountain socio-ecological-technological systems under climate change.
