Regional developments: Africa [in 2025 GFPR]

Africa’s food systems have undergone significant transformations over the past four decades, with notable improvements in agricultural productivity and food security, but persistent challenges remain. This chapter examines how Africa’s agrifood policy landscape has evolved over time in response to complex challenges, including food insecurity, climate change, and socioeconomic disparities. It explores how IFPRI and other international organizations have offered research-based solutions to Africa’s development challenges, as well as underscoring the necessity of systemic, inclusive, and evidence-based approaches to address the agrifood system challenges projected for 2050.

Informing CAADP 2026–2035: What a decade of IFPRI Research in Africa tells us

Informing CAADP 2026–2035: What a decade of IFPRI Research in Africa tells us

This policy brief distills insights from a decade of IFPRI’s research and engagement across 54 African countries, offering a strategic synthesis to inform the Kampala 2026–2035 implementation phase of the Comprehensive Africa Agriculture Development Programme (CAADP). Drawing from almost 5,700 publications between 2015 and 2025, and using a combination of natural language processing (NLP), deep learning algorithms and rule-based approaches, the review maps key findings against CAADP’s six strategic objectives: (1) intensifying sustainable food production, agro-industrialization, and trade; (2) boosting investment and financing for agrifood systems transformation; (3) ensuring food and nutrition security; (4) advancing inclusivity and equitable livelihoods; (5) building resilient agrifood systems; and (6) strengthening agrifood systems governance. By aligning evidence with strategic priorities, this synthesis aims to sharpen the research and policy agenda needed to accelerate agricultural transformation, ensure food security, and deepen resilience across the continent. The review reveals areas of significant progress—such as advances innovative finance, nutrition policy, social protection design, gender equity, and market functioning—while also exposing enduring gaps in data, investment diagnostics, and imple mentation capacity. The brief is thus both a stocktaking and a springboard, harnessing what is known to guide the next phase of CAADP.

Navigating Nigeria’s food system challenges in the face of inflation and reform

Navigating Nigeria’s food system challenges in the face of inflation and reform

Main Messages: 1. Low-income households in both urban and rural areas are hardest hit by rising food prices. Post-reform (fuel subsidies removal and exchange rate liberalization) price shocks and persistent inflation have disproportionately affected poor urban and rural households, forcing them to reduce food consumption and dietary diversity. Malnutrition and food insecurity are on the rise, particularly among children and women-headed households, with sharpest impacts in conflict-affected areas. 2. Small-scale farmers are not benefiting proportionately from price increases. Despite surging food prices, small-scale farmers face escalating input costs, poor market access, and structural in-efficiencies that leave them with marginal gains far below the rate of inflation. 3. Trading networks maintain healthy margins, amplifying systemic inefficiencies. Traders and intermediaries dominate the food supply chain, passing on increased costs to consumers while pre-serving or even increasing their profit margins, highlighting inequities in the distribution of benefits along the value chain. 4. Recent economic reforms and external shocks exacerbate structural weaknesses. Economic reforms, including the removal of fuel subsidies and exchange rate adjustments, have amplified existing challenges in the food system, including high transport costs, inadequate infrastructure, and fragmented markets. 5. Policy interventions should protect vulnerable groups and strengthen local food systems. Addressing these disparities requires targeted safety nets for consumers, support for small-scale farmers, and systemic investments to reduce inefficiencies in the value chain while promoting cli-mate-resilient food systems.
