Fertilizer Crunch Pushes African Nations Toward Agroecology
Soaring fertilizer prices and supply chain disruptions are forcing a reckoning across African agriculture. Some governments and farming communities are turning to agroecology—a low-input approach that critics once dismissed as marginal but which is increasingly attracting serious policy attention.
The arithmetic is unforgiving. Africa imports roughly 90 percent of its fertilizer requirements, according to the African Development Bank, and those imports have become dramatically more expensive since 2022, when the war in Ukraine disrupted global supply chains and pushed urea prices to multi-year highs. For smallholder farmers across sub-Saharan Africa—who produce the bulk of the continent's food on plots of under two hectares—the result has been a choice between buying less fertilizer, going into debt, or doing without.
Many are doing without.
That fertilizer gap, once framed as a productivity problem amenable to increased imports, is now prompting a more fundamental reassessment. Governments in Kenya, Senegal, and Ethiopia have expanded support for agroecological approaches—methods that rely on biological processes, organic matter cycling, and diversified cropping systems rather than synthetic inputs. The shift is tentative and uneven, but it represents a notable departure from decades of policy orthodoxy that equated agricultural development with increased fertilizer use.
A practice with roots, and renewed urgency
Agroecology is not a single technology but a bundle of practices: intercropping legumes with cereals to fix nitrogen in soil; composting crop residues instead of burning them; integrating livestock to close nutrient loops; using agroforestry to improve microclimates and soil structure. The methods have been practiced informally across Africa for generations. What is new is the formal policy embrace.
Kenya's government included agroecology in its 2023 National Agricultural Investment Plan update, citing resilience benefits in the face of climate variability. Senegal's national dialogue on agricultural development in 2024 produced recommendations to scale farmer-managed seed systems and reduce dependency on imported fertilizers. Ethiopia's Productive Safety Net Programme, one of the largest social protection schemes in Africa, has increasingly incorporated land management practices aligned with agroecological principles.
The timing reflects a confluence of pressures. Fertilizer prices have moderated since their 2022 peaks but remain elevated relative to pre-pandemic baselines. The African Union's fertilizer summit in 2022 set a target of tripling fertilizer use across the continent by 2030—but that target assumed continued access to global markets at affordable prices, an assumption that the recent disruption called into question.
The yield question
The central objection to agroecology has always been productivity. Critics—including some within the international agricultural research establishment—argue that low-input systems cannot close the yield gap that separates African agriculture from its global peers. Food security advocates worry that premature pivots away from intensification risk undermining the very populations these policies aim to serve.
That concern is not groundless. A 2023 meta-analysis published in a peer-reviewed journal found that agroecological systems in sub-Saharan Africa produced, on average, 20 to 30 percent lower yields than conventional systems over comparable plots. The gap narrowed significantly in drought years, when diversified systems demonstrated greater resilience—but in normal conditions, the trade-off was real.
Proponents contest the framing. They note that yield-per-hectare comparisons often exclude the full set of outputs from diversified farms, which typically produce vegetables, fruits, and animal products alongside staples. They argue that the systemic costs of conventional agriculture—soil degradation, water depletion, pest resistance—are inadequately priced into the comparison. And they point to evidence that agroecological practices can close much of the gap when combined with improved seed varieties and better agronomic advice.
The evidence base remains contested, and there is genuine disagreement among serious researchers about the pace at which agroecological transitions can proceed without risking food production. What is clear is that the previous consensus—scaled fertilizer, high-yield varieties, market integration—is no longer treated as sufficient by a growing number of African policymakers.
Structural context: who controls the inputs
The fertilizer question is also, irreducibly, a question about power. Three companies—Yara International, CF Industries, and Mosaic—control a substantial share of global nitrogen fertilizer production and trade. Supply disruptions, whether from war, sanctions, or market speculation, transmit rapidly to African farmgate prices. There is no African countervailing actor of comparable scale.
This structural dependency has long been noted by analysts of African agricultural policy. What changed is that the dependency became politically visible in a way it had not before. When fertilizer shipments were delayed in 2022 and prices spiked, the political cost fell on governments that had promoted intensification strategies without adequate attention to supply chain resilience.
Some development finance institutions have quietly adjusted their guidance. The African Development Bank's agricultural strategy now includes explicit language about diversification of input supply chains, including domestic fertilizer production and reduced-input systems. The World Bank's Country Partnership Frameworks for several sub-Saharan nations have added language on climate-resilient agriculture that encompasses practices beyond conventional intensification.
This does not represent a wholesale reversal of the input-intensive development model. Multinational agribusiness continues to have significant influence over the policy frameworks promoted by major donors. But the Overton window on agricultural policy in Africa has shifted—and agroecology is now discussed in rooms where it was previously excluded.
Stakes and what comes next
The trajectory matters across multiple timescales. In the near term, farmers who reduce fertilizer use without adequate substitution strategies risk immediate yield losses. In the medium term, wider adoption of agroecological practices—if accompanied by the agronomic support, market access, and policy incentives required—could reduce Africa's exposure to volatile global input markets and build soil carbon that conventional tillage depletes. In the long term, the question is whether a continent that imports the nitrogen that feeds its crops can build food systems that are genuinely sovereign.
That is the largest stakes question, and it sits beyond what any single article can resolve. What the current moment reveals is that the previous answer—integrate into global markets and trust that trade will deliver inputs at acceptable prices—is no longer the only answer available. Governments in Nairobi, Dakar, and Addis Ababa are exploring alternatives, imperfectly and with real trade-offs, but with a seriousness that would have been difficult to imagine a decade ago.
The fertilizer crisis did not create that shift. But it accelerated it, and it has given agroecology a policy relevance it previously lacked.
