| Research Abstract |
On one hand, based on farm surveys, cultivation tests andswamp-to-paddy field conversion tests conducted in Uganda, it was verified that ricecultivation under rainfed and simple-irrigation is sustainable and contributes toincreasing income of small farmers. On the other hand, in order to identify the adverseimpacts agriculture intensification in Sub-Saharan Africa gives to such aquaticenvironments as rivers, lakes and swamps, a model was built to estimate changes in thewater quality of the aquatic environments from the relationship among Chlorophyll-a,total phosphorus and total nitrogen using the data of lakes in the European continent. Integrating the results from these researches, the conditions of a‘low-input-environment-friendly agriculture' model for Sub-Sahara Africa areidentified.
