Resumen
Increasing crop production, while maintaining sustainability, is a priority for agricultural development projects, particularly in developing countries. This study investigated the factors contributing to the effectiveness of agricultural development projects in improving the sustainability of cropping systems in a small upland watershed in south-west China. This involved a review of recent related projects and detailed evaluation of one project: the SHASEA Project. Farmers? perceptions of several agricultural technologies are discussed, along with factors contributing to farmers? adoption of these technologies. Local, national and international institutions need to adopt several strategies to improve project effectiveness and agro-environmental sustainability.
