Africa rice farming system

"Africa rice farming system"
Development of sustainable rice cultivation and food production system in Africa

We will create new technologies and knowledge that will lead to increased rice production, a key crop in the region, and improved nutrition for the people, with the aim of building a sustainable food production system with resource utilization, centered on rice cultivation.
Africa upland farming system

"Africa upland farming system"
Development of soil and crop management technologies to stabilize upland farming systems of African smallholder farmers

Our activities aim to develop and disseminate stable and sustainable land and cultivation management technologies for small-scale farming systems in the African savanna areas, where the natural environmental conditions are very different.

Science and Technology Research Partnership for Sustainable Development (SATREPS) Projects

Project on establishment of the model for fertilizing cultivation promotion using Burkina Faso phosphate rock

"" ""
In Burkina Faso, there are 100 million tons of phosphate rock underutilized due to its low quality. Effective utilization of this PR resources must contribute to increasing agricultural productivity.

Fertility sensing and variety amelioration for rice yield (FY VARY) project

"" ""
Madagascar is one of the largest rice producers in Africa with a per capita rice consumption twice as high as that of Japan. We will develop rice production techniques to realize high yield even under low fertility conditions and evaluate the impact that adopting such techniques has on local farmers' income and nutritional status.
