Stable Food Production
Technology development for increased productivity and stable production of agricultural products in the tropics and other unstable environments
The Stable Food Production Program corresponds to “Technology development for increased productivity and stable production of agricultural products in the tropics and other unstable environments", as identified in JIRCAS’ Third Medium-Term Plan. This will develop technologies to improve and sustain productivity through collaborative research with local institutions and international research centers in specific research fields wherein Japan has shown predominant comparative advantage, especially for areas in adverse environments such as those found in tropical regions. Likewise, reducing starvation and malnutrition which remain as serious problems in developing regions, and contributing to food security in the world and in Japan are also parts of its targets.
Hereunder is a summary of the flagship project of the program, "Development of rice production technologies in Africa" and other projects.

Presentation of JIRCAS international collaborative project outputs at the “Research for Development (R4D) Week” of the International Institute of Tropical Agriculture
JIRCAS has been working with the International Institute of Tropical Agriculture (IITA) on the collaborative project, titled “Evaluation and Utilization of Diverse Genetic Materials in Tropical Field Crops (EDITS),” focusing on yam and cowpea, which are important regional crops in Africa. This project is aimed at advancing crop breeding activities.
Cowpea germplasm database focusing on grain quality-related traits is now ready for access
The “EDITS-Cowpea” project is one of JIRCAS initiatives that have been implemented to generate fundamental scientific information to promote better utilization of the wide genetic diversity of this crop in breeding programs and crop utilization. Based on the information generated through the project, we have created the "EDITS-Cowpea database" (http://www.jircas.go.jp/en/database/edits-cowpea/introduction).
