This article is based on comparative anthropological fieldwork conducted in the Alpine region of Switzerland on sustainable environmental knowledge about natural hazards related to climate change. It examines ways to complement the normative and technological practices of risk management by using local knowledge to improve the resilience of affected communities against climate- related risks. The study shows how agricultural practices and knowledge may contribute to sustainable behavior towards nature and the environment. It explores how local environmental knowledge, perceptions, and handling strategies of climate-related risks may be integrated within a renewed concept of environmental sustainability. Participatory GIS mapping (PGIS) is the primary research method used. Based on applied visual anthropological methods, PGIS is a cartographical approach that integrates local perceptions and strategies of action drawn from interviews and participant observation. This approach enables improved communication of local knowledge and contributes to interdisciplinary cooperation between different academic fields, such as social anthropology, geography, and civil-engineering in the context of technological risk management. The approach encourages the active participation of local people in the process of sustainable risk management through the integration of cultural meanings and local knowledge about the sustainable management of sensitive natural environments.
