| Abstract: | Rising pressures of population and resource use in the humid tropics make the establishment and maintenance of more productive yet sustainable agricultural systems ever more necessary. This is particularly so for the small-scale farmers who form the majority of the poor population in many countries. A range of agricultural practices that can improve output on a sustained basis are already well recognized. These include more effective fallow-management, fertilization and manuring, improving tillage practices, intercropping and agroforestry.While the scientific community has achieved much in the humid tropics, the potential contribution of indigenous cultivators is increasingly recognized and progress will demand their integration into the research and development process.The search for sustainable production must confront not only many ecological constraints but also many of an economic, social and political character. The wider development process discriminates against the strengthening of sustainable agriculture and tends to generate more exploitative forms of production. This is evident, for instance, with the spread of poor, inexperienced farmers into humid tropical colonization zones. Effective diffusion of ecologically sound agriculture in the humid tropics requires the inclusion of a full socioeconomic perspective as part of an interdisciplinary approach to this crucial problem of land management. |
