This article examines the relation between poor women and men and common property resources (cprs). It locates poor people's use of cprs within a wider focus on sustainable livelihoods, which argues that development initiatives need to build on people's assets and strengths, and identifies cprs as a crucial element of poor people's coping and adaptive strategies. The article considers evidence from India and West Africa with a particular focus on poverty reduction, equity, gender and management issues. Development agencies and governments which have re-focused their attention on poverty in recent years will find that cprs provide an entry point to understanding poor people's perceptions of poverty and for building on their capacities.
