Maize yield responsiveness and profitability of fertilizer: New survey evidence from six African countries

Enhancing maize productivity growth is pivotal for revolutionizing the agrifood system in Africa, with inorganic fertilizer serving as a fundamental input for catalyzing this progress. However, concerns are mounting about the low and decreasing yield response and profitability of inorganic fertilizer use, particularly in Sub-Saharan Africa. This study aims to refine yield response and profitability models by incorporating recent data from nationally representative and panel datasets spanning six countries. Most countries exhibited low nitrogen yield responsiveness (4–7 kg), while Ghana and Uganda showed higher responsiveness (15–20 kg) per additional 1 kg of nitrogen. Analysis of fertilizer-to-maize price ratios from 2010 to 2023 showed a downward trend, with spikes in 2022 in Ghana, Malawi, Nigeria, and Tanzania. Overall, except for those years, the data suggest a trend of increasingly favorable price incentives for fertilizer use. Ethiopia, Tanzania, and Uganda experienced declines in the fertilizer-to-maize price ratio. Increasing inorganic fertilizer use would be profitable in Ethiopia, Ghana, Nigeria, and Uganda at current market prices, but not in Malawi or Tanzania. Subsidies in Malawi and Tanzania have boosted profitability, but these may not be necessary in Ghana, Nigeria, or Uganda, which already have favorable price incentives; Malawi could benefit by substantially reducing its 80 percent subsidy while maintaining decent price incentives and farm profits. The paper proposes policy options based on factors influencing yield responsiveness and potential improvements drawn from new modeling and synthesis of the literature.

Economic and welfare implications of the reduction of US foreign assistance in Malawi

Economic and welfare implications of the reduction of US foreign assistance in Malawi

For over a decade, the US has consistently ranked as either the largest or second-largest donor to Malawi. Annual foreign assistance disbursements have averaged over $360 million between 2020 and 2023. In January 2025 the US government suspended all US-funded foreign aid programs. As of April 2025, the available information suggests that funding for many of these programs in Malawi has been withdrawn, resulting in an estimated decline in US foreign assistance to Malawi of around 59% for 2025. As a result, Malawi faces a potential decline in foreign exchange inflows of around $177 million in 2025, a loss equivalent to approximately 6.3% of the annual merchandise import bill. With Malawi’s economy currently highly vulnerable, lacking the buffers needed to absorb shocks, the eco nomic and welfare implications of these recent events are concerning. The suspensions may lead to an economic contraction from reduced activities by US implementing partners, immediate pressure on the exchange rate (endangering the affordability or availability of critical imports) and declining productivity in key sectors such as agriculture. Deteriorating health and education outcomes could further affect the productivity of workers in the longer run. In this policy note we combine qualitative and quantitative information gathered in-country with modeled results of the possible economywide impacts of the reduction of US foreign assistance on key economic and welfare indicators over the next six years. We also discuss policy options that could help mitigate some of the adverse impacts.

Malawi: Systematic analysis of domestic production and world market shocks

Malawi: Systematic analysis of domestic production and world market shocks

This study explores Malawi’s vulnerability to economic shocks and identifies those contributing most to economic uncertainty. The Malawian Computable General Equilibrium (CGE) model was employed to simulate a range of potential economic outcomes under various sampled shock scenarios developed using historical data to capture domestic agricultural yield volatilities and world market prices uncertainty for traded goods. Data mining and ma-chine learning methods were applied to quantify the contribution of each shock to the uncertainty of economic outcomes (gross domestic product [GDP], private consumption, poverty, and undernourishment). Key findings sug-gest that domestic cereals and oilseeds yield volatility risks are the most important for the uncertainty of total GDP and consumption across all household types except rural low-income households. Rural low-income households’ consumption and poverty are exposed to a wide range of risks, including production volatility of livestock, yield volatility of oilseeds, cereals, vegetables and world market price of beverage crops. Finally, for undernourishment outcomes, volatility in the yields of staple cereals is the dominant risk factor for all household types. Understanding how possible shocks would impact various segments of the Malawian economy and population is a critical first step in facilitating discussions on relevant risk mitigation strategies, such as increasing average crop yields, adopting technologies and practices that narrow yield uncertainties, or diversifying production away from risky crops and sectors.
