This article describes three environmental development projects run by CARE Austria in Uganda, Kenya, and Guatemala. Some of the common features and experiences from the projects emphasize the necessity for maintaining flexibility during the entire period of the projects in order to be able to find answers to the changing needs of the beneficiaries. This calls for an adaptation to local structures and traditions which requires the ability and the willingness of them to participate. Interventions are restricted to local initiatives or institutions with the aim of enhancing their technical and organizational capabilities. Therefore, CARE Österreich prefers to employ local professionals for the management of projects. Participation is designed to be as broad as possible in order to incorporate all wishes, concerns, and doubts of the potential beneficiaries during the planning and design process.
