Doubling Africa's rice production by 2050

By Scout Nelson

A study published in Nature Communications reveals significant opportunities to increase rice production in Africa. Led by University of Nebraska–Lincoln professor Patricio Grassini, the research team advocates for enhanced agronomic practices to boost yields and ensure food security.

Africa, which imports nearly 40% of its rice, faces a critical need to improve domestic production as demand is set to more than double by 2050 due to population growth and increased consumption.

The study, supported by the Bill and Melinda Gates Foundation and involving researchers from several prestigious institutions, identifies low current yields as a major bottleneck. With improvements in soil and plant nutrition, weed control, water management, and moderate cropland expansion, Africa can significantly enhance its rice output.

This approach aims to meet the future demand of 150 million tons by 2050 without further increasing rice imports and reducing the environmental impact of expanding agricultural land.

Africa's dependence on rice imports makes it vulnerable to supply and price shocks, a situation highlighted by recent export bans from major rice-producing countries. Boosting domestic rice production through the recommended agronomic improvements offers a sustainable path to self-sufficiency and resilience against global market fluctuations.

The research emphasizes the role of advanced crop simulation modeling and on-the-ground data collection in identifying yield improvement opportunities. This methodology not only has implications for African rice production but also offers insights for agricultural practices worldwide, including in Nebraska.

By focusing on crop improvement and informed decision-making, the study reflects the University of Nebraska–Lincoln's global research impact. It underscores the importance of collaborative research in supporting agriculture stability and food security globally, benefiting producers and communities far beyond Nebraska's borders.
