Global Environment Facility (GEF) Small Grants Programme (SGP) has been involved in Community-Based Adaptation (CBA) since 2008. At this time, the GEF Strategic Priority on Adaptation (SPA) window funded a five-year pilot programme that was implemented by UNDP and delivered on the ground by SGP. In 2009, AusAID partnered with SGP to enable climate resilience funding for two complementary CBA programmes, the Mekong Asia Pacific CBA (MAP CBA) and the Small Islands Developing States CBA (SIDS CBA).One of the key objectives of SGP’s CBA programmes is to mainstream CBA into the local, sub national and national levels by informing policies and programmes of community-driven adaptation priorities and innovations. While every country’s planning processes and capacities vary substantially, one of the greatest barriers for government’s effective development processes is how to reach vulnerable local people, especially those living in isolated geographic areas. This guidance note is targeted to SGP CBA practitioners such as National Coordinators (NCs), grantees and Programme Assistants (PAs) to effectively integrate CBA innovations into national processes and practices, while using the existing infrastructure and systems of SGP. It can also be used by other practitioners working at the local levels.
