This note examines the relationshipsbetween climate-related vulnerabilities, adaptationpractices, institutions, and external interventions to showthe role and importance of local institutions in climatechange. It proposes an analytical framework to classifyadaptation practices based on their relationship todifferent forms of environmental risks. It examines pastadaptation responses to climate change, their impacts on thelivelihoods of the rural poor, and the role of institutionsin facilitating external support for adaptation. Thediscussion uses evidence from two sets of cases - those inthe United Nations Framework Convention on Climate Change(UNFCCC) coping strategies database, and in the NationalAdaptation Programs of Action (NAPAs) - to comparativelyassess the role of local rural institutions in facilitatingadaptation. Focusing on three types of institutions -public, private, and civic, a review of case studiesindicates that local institutions play a crucial role inshaping adaptation to climate change: they connecthouseholds to local resources and collective action;determine flows of external support to different socialgroups, and link local populations to nationalinterventions. The lessons from this review are finally usedto make recommendations about the operational significanceof local institutions and institutional analysis in thecontext of climate change.
