Modelling tool explores how climate-smart policies affect crop production

GCRF-AFRICAP (2022) Agricultural and food system resilience: Increasing capacity and advising policy   A Global Challenges Research Fund programme to help agriculture and food production in sub Saharan Africa become more productive, sustainable and resilient to climate change. #36 p.

Over 200 experts from the GCRF (Global Challenges Research Fund) -Agricultural and Food System Resilience: Increasing Capacity and Advising Policy (AFRICAP) project spent four years working with governments, civil society and the private sector in Malawi, South Africa, Tanzania and Zambia to build an evidence base for making sub-Saharan agriculture more productive, sustainable and resilient.

Read the AFRICAP final report.

The researchers developed the integrated Future Estimator for Emissions and Diets (iFEED), a first of its kind tool that shows how climate change and government policy will affect crop yields, land and water use, and how nutritious diets will be. They found that even a small increase in average temperatures could trigger severe food system shocks.

Without urgent action, Malawi’s maize yields could fall by one fifth by 2050, and demand for water irrigation in South Africa could rise by 84%. In the most extreme climate impacts scenario, Zambia could see its crop yields fall by over 20% by 2050 – against a backdrop of an almost three-fold population increase. Tanzania could experience declines in labour productivity and an increased reliance on food aid – with women and girls bearing the brunt.

On the flip side, by aligning national policies on technology, agriculture, infrastructure and food security, Malawi could increase overall crop production by more than 700% and livestock production by over 150%. With the right mix of policy and innovation, Tanzania could increase crop production 17 fold (1676%) – and double livestock production; and by better connecting local and global trade markets, Zambia could increase overall crop production by 564% and double livestock production. In South Africa, strong land and tenure reforms would see arable areas reduce in size but crop varieties improve.
“This research gives governments some of the information and evidence they need to get ahead of climate impacts by implementing reforms that enhance resilience, boost nutritional outcomes, and enhance livelihoods. By providing training and support for vulnerable farmers, investing in new agricultural methods, diversifying crop production and importing nutrient-dense foods to supplement domestic production, they can build food systems that are fit for the future we know is coming.” Professor Tim Benton, Director of Chatham House’s Environment and Society Programme
