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

Related Research Program



Sub-Saharan Africa is the world's most food insecure region, with one in four people chronically hungry. In order to secure a stable supply of food for the region and achieve the eradication of hunger set forth in the SDGs, food production technology that can adapt to the increasingly unstable growing environment and effectively utilize limited resources such as water and nutrients is required. To this end, we will create new technologies and knowledge that will lead to increased production of rice, a key crop in the region, and improved nutrition for the people, with the aim of building a sustainable food production system centered on rice cultivation.

Rice productivity is limited due to unstable water conditions, degraded soils with poor nutrient supply, and low fertilizer inputs by farmers.


Develop new technologies and knowledge that will lead to a sustainable and nutrition-sensitive food production system centered on rice by integrating water management technologies, breeding materials and cultivation technologies, and to provide them to the target countries.


Development of breeding materials with enhanced adaptability to unstable production environments, improved nutritional quality and marketability

Development and evaluation of food production systems that make effective use of water and soil nutrients, leading to increased rice production, improved nutrition, and higher incomes for farmers

Research Themes

  • Elucidation of the potential of paddy rice cultivation in Africa and development of technology to maximize output
  • Development of breeding materials for rice and vegetables that contribute to increased food production and improved nutrition in Africa
  • Development and impact assessment of cultivation technologies and production systems with excellent resource utilization that lead to improved nutrition and higher income

Target Countries

Madagascar, Tanzania, Guinea

Target Beneficiaries

Research institutes in target countries, extension organizations (members), research institutes in other countries, international research institutes, international development projects
