Impacts of climate change are location-specific, hence the need to develop targeted solutions and strategies. Local government units, in partnership with the International Institute of Rural Reconstruction, established farmer learning groups which are platforms for knowledge generation and sharing on climate change action-research. The project was implemented in learning communities in Guinayangan, Quezon and Ivisan, Capiz, Philippines. Facilitating learning groups involved social learning methodological processes: vulnerability assessments, setting of learning agenda, participatory action research implementation, community mobilizing and knowledge sharing. Action research, in both municipalities, showed that knowledge generation through a small group of farmer innovators is an effective strategy in the identification and refinement of appropriate technologies. The learning group members serve as a support to the local extension system, helping accelerate adaptation of various climate-smart technologies.
