Nature's contributions to human well-being under climate change: Evidence from Central and Eastern Madagascar

Anthropogenic climate change has an unprecedented impact on ecosystems and their services, with severe consequences for human well-being, particularly for the marginalised and vulnerable members of society in the Global South. The well-being of communities relies not only on material and regulating services ecosystems provide but also on non-material services. In this paper, we unravel the diverse ways that climate change impacts affect Nature's Contributions to People (NCP) and the well-being of rural populations in four sites in Madagascar—a biodiversity hotspot but one of the economically poorest countries in the world. We conducted participatory community workshops, mapping and semi-structured interviews with local residents across social subgroups to understand the mechanisms of climate-related degradation and the resulting impacts on different dimensions of human well-being through an NCP lens. We found that non-material services are generally more often associated with well-being effects. Climate change degrades material and non-material services through sea level rise, biodiversity loss, drought, precipitation and temperature variability, with consequences for materials, companionship and labour, food and feed, and physical and psychological experiences. Loss of land and forests is expressed through ecological grief. The outcome of our research provides evidence-based information to local policymakers, conservation practitioners, and climate change agencies. This information can help improve government efforts toward holistic conservation and climate change adaptation by addressing the impacts on the physical and mental well-being of the most vulnerable communities.
