This research highlights how membership in farmer organisations plays a critical role in helping smallholder farmers across the Pacific adapt to climate change. By being part of organised networks, farmers gain better access to information, training, resources, and collective support that strengthen their ability to respond to climate risks such as extreme weather, changing rainfall patterns, and food insecurity. Farmer organisations also amplify farmers’ voices in policy and decision-making spaces, support knowledge-sharing between communities, and strengthen livelihoods through coordinated action. Strengthening farmer organisations is therefore key to building resilient, climate-smart farming systems and improving food and nutrition security in Pacific Island countries.
