Strengthening community rights to manage land and resources is showing promise as an approach to deliver on biodiversity, climate change mitigation, and land degradation objectives. Clear principles and fundamental design characteristics have emerged from extensive research to guide interventions to support and establish robust governance of local “commons” – and interventions often fail when these are not followed. There is a clear need and opportunity for the GEF to stimulate transformational change through restoring, strengthening, or establishing sound and inclusive community-based governance of traditional “commons”, promoting achievement of global environmental benefits.
