TERRA Africa Project Workshop Held in Nigeria <br> —Toward the Development and Implementation of Regenerative Agriculture Packages—
On August 27 and 28, 2026, the Japan International Research Center for Agricultural Sciences (JIRCAS) held a workshop for the TERRA Africa Project at the headquarters of the International Institute of Tropical Agriculture (IITA) in Ibadan, Nigeria. The workshop, themed “Strengthening Science-Based Regenerative Agriculture Packages for Sustainable Farming Systems in Africa,” was attended by approximately 35 researchers and stakeholders from Japan, Ghana, Nigeria, Mali, Uganda, and Ethiopia, including representatives from the Sasakawa Africa Association (SAA), universities, national research institutions, IITA, and the Forum for Agricultural Research in Africa (FARA). An additional 10 participants joined online.

554. Enhancing the Function of Water Facilities at the African Farmer Level
Sub-Saharan Africa imports increasing amounts of rice from Asia and North America each year to meet growing domestic rice consumption. In order to realize the goal of doubling rice production in Africa, it is essential to efficiently and sustainably cultivate rice in lowland areas. However, earth canals maintained with farmer-level technology are eroded by water runoffs and rainfall, reducing the function of the canals and making it impossible to plant rice. JIRCAS has prepared and released a manual that enables local farmers to construct low-cost irrigation facilities and maintain over the long term with their own technology. -
