National organizations and networks of smallholder forest producers play an important role in contributing to climate change mitigation and adaptation, spanning political and practical action. Innovative and successful climate action builds on the particular strengths of each organization, and harnesses both the support of the membership base as well as organizational alliances in multi-actor networks. The wide agenda combining both technical and political issues on forests and climate change require both strong capacity and skillful leadership in order to balance the donor interests linked to considerable external funding with internal accountability towards local smallholder members and long-term strategic goals. Smallholder forest organizations should be recognized and supported in their quest for solutions that benefit rural economies while responding to climate change and ensuring a more integrated approach that also addresses other development goals. This publication summarizes the findings of a review of the innovative ways in which smallholder forest producer organizations in developing countries are contributing to climate change mitigation and adaptation. The review was carried out by the Finnish Agri-Agency for Food and Forest Development (FFD) and the Finnish Environment Institute (SYKE), in collaboration with the Forest and Farm Facility (FFF), a partnership among the Food and Agriculture Organization of the United Nations (FAO), the International Institute for Environment and Development (IIED), the International Union for Conservation of Nature (IUCN) and AgriCord.
