Biosphere reserves represent important laboratories for testing innovative approaches to sustainable regional development. In recent years, increasing attention has been paid to the role of smart innovations, particularly those that combine digital technologies, open data infrastructures and participatory governance. This paper analyses selected examples of smart innovations implemented in European biosphere reserves, with a particular focus on their contribution to the development of social potential in these territories. The study applies a qualitative research design based on the analysis of 205 European biosphere reserves. Initial case identification was supported by AI-assisted screening, and subsequently validated using secondary sources, including official websites, project documentation and scientific publications. The findings indicate that the most advanced biosphere reserves apply integrated monitoring systems combining remote sensing, sensor networks and participatory data collection. At the same time, open biodiversity databases, socio-environmental observatories and digital communication platforms enable broader access to environmental information, and support collaboration between researchers, public authorities and local communities. Examples from biosphere reserves such as Sierra Nevada, Menorca, Wadden Sea, North Devon, Nordhordland and Kristianstads Vattenrike demonstrate how smart tools can strengthen participatory governance, knowledge exchange, and evidence-based decision-making. The results suggest that biosphere reserves can function not only as sites of technological innovation, but also as platforms for social innovation, where digital tools and participatory approaches contribute to sustainable regional development.
