Three quarters of Vietnam'sland area is in the uplands and foothills,which contain some of the poorest communes inthe country. The Ngoc Lac Natural ResourcesConservation and Management Project, in ThanhHoa Province, is one of several large uplandrural development projects that receivessubstantial funding from foreign governments inVietnam. The project was designed in 1995 toaddress the environmental constraints tosocio-economic development of Ngoc LacDistrict, while improving agriculturalproduction and natural resources management.During the first three years of operation, theproject focused on the introduction anddissemination of various (...) ``model'' technologicalpackages for improved agriculture, forestry,and animal husbandry. These models includedtree nurseries, sloping agricultural landtechnologies, integrated fish pond-livestockpen-home garden systems, and several animalhusbandry activities. However, the distributionof the models was not socially equitable, thesustainability of the models by model farminghouseholds proved problematic, and the adoptionof these technology practices by non-modelhouseholds was quite low. Four lessons can beidentified from past rural developmentexperience: beware of ``participatory'' ruralappraisal, start small and go slowly, introducelimited technologies, and help farmers adaptthe technologies. There are two promisinginitiatives underway in Vietnam. These are theparticipatory curriculum development and theparticipatory technology developmentinitiatives of the Social Forestry SupportProgram.
