Climate change and the collapse of biodiversity are transforming our world. Faced with this ecological emergency, the key question is: what can we do about it? The answer lies in the relationship between human societies and the living world (natural environments, animals, plants) that surrounds them. This book, edited by Olivier Barrière of the IRD (Institut de Recherche pour le Développement), brings together researchers and local players from the South and North, and explores the idea that humanity cannot survive without the rest of the living world. This “socio-ecological coviability” is essential to guarantee our common future. This book provides the keys to understanding and taking action. 240 pages book, in French. Patrick FRÉMEAUX
