"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

Report on TICAD 8 Side-Event “Managing African Soil for Food Security and Environmental Sustainability”

An official side event of the 8th Tokyo International Conference on African Development (TICAD 8) entitled “Managing African Soil for Food Security and Environmental Sustainability” was organized by JIRCAS on August 30, 2022, with the support of the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA).

JIRCAS Publishes Technical Manual for Efficient Use of Water Resources in Irrigation Schemes in Africa

JIRCAS has released a "Technical Manual for Efficient Use of Water Resources in Irrigation Schemes", which describes several methods that contribute to improving water use efficiency in Africa, particularly in response to water resource constraints and facility degradation that are expected to become more serious in the future.

Manual for Development of Low Cost Water Facilities in Africa Published

In Africa, most drainage channels in paddy fields constructed by farmers are earth canals, which are easily eroded by strong rains and running water, and result in diminishment of canal functions. We have published a manual that introduces inexpensive reinforcement measures for irrigation canals (reinforcement using cover-plants, wooden fence, and soil bricks) that can be implemented by farmers.
