The present article reviews the adaptation of the popular farmer field school (FFS) approach to integrated watershed management in several Indonesian provinces, under the auspices of a major environmental management project. Indonesia is the site of origin of the FFS concept, developed to promote integrated pest management (IPM) in rice during the 1980s. Since the conclusion of the National IPM Programme in 1999, FFS alumni groups and approaches have continued to evolve in Indonesia, and the FFS model has been taken up in scores of developing countries around the world.
