African agribusiness ecosystems are increasingly threatened by the multifaceted impacts of climate change, including rising temperatures, erratic rainfall, and frequent extreme weather events. These disruptions pose significant risks to food security, rural livelihoods, and sustainable development across the continent. This paper explores integrated strategies for enhancing climate resilience in African agribusiness, drawing on resilience theory and systems thinking as guiding conceptual frameworks. It synthesizes current developments in climate-smart agriculture (CSA), the role of indigenous knowledge systems, regional carbon market mechanisms, and the need for improved policy coherence. The study draws from a wide range of empirical literature, regional initiatives, and policy documents, including the African Union Commission’s Climate Change and Resilient Development Strategy and Action Plan (2022-2032), to examine how scientific innovations, traditional practices, financial instruments, and inclusive governance can contribute to sustainable adaptation. Emphasis is placed on the active participation of women and youth, equitable access to resources, and the transformation of entire agrifood value chains. The findings suggest that the adoption of CSA and other resilience strategies remains uneven due to structural and institutional barriers. However, opportunities exist to scale successful models through enhanced coordination, policy alignment, and investment in climate-resilient infrastructure and knowledge platforms. The paper concludes by proposing strategic policy pathways and practical recommendations to support the transformation of agribusiness ecosystems into resilient and inclusive systems capable of withstanding current and future climate risks.

Climate change and agricultural transformation are increasingly affecting cocoa production in Sub-Saharan Africa, where smallholder farmers face growing environmental and socioeconomic constraints. This study investigates their effects on cocoa productivity in the Mvila Division of South Cameroon, with particular attention to agricultural modernization, rainfall variability, cooperative membership, fertilizer use, and farm-level characteristics. The study combines qualitative evidence from administrative and policy documents with quantitative data from cocoa farmers and secondary sources, including MINADER, IRAD, FAOSTAT, ICCO, CHIRPS, and the National Cocoa and Coffee Board. Descriptive statistics, correlation analysis, multiple regression, robustness tests, and scenario projections were used to assess productivity across five subdivisions. The results show that cooperative membership, favourable rainfall conditions, farmer education, fertilizer use, and farm size significantly increase cocoa productivity, while ageing plantations reduce yields. Agricultural transformation has also strengthened farmer organizations, extension services, and adoption of improved practices, although mechanization remains constrained by inadequate infrastructure, limited finance, and uneven institutional support. Ebolowa I and Ebolowa II consistently record higher productivity, associated with stronger institutional support and greater adoption of improved practices. The study contributes empirical evidence on the interaction between climate variability and agricultural transformation in cocoa-producing smallholder systems and highlights the importance of combining climate-smart practices, plantation rehabilitation, producer organizations, extension services, and appropriate mechanization to improve productivity and strengthen farmers' resilience in Cameroon.

Drawing on multi-wave panel data from over 5,000 households in the World Bank’s Living Standards Measurement Study–Integrated Surveys on Agriculture microdata across Ethiopia, Tanzania, Uganda, and Malawi, this study investigates how fertilizer subsidies interact with rainfall variability to influence maize productivity among East African smallholders. Using a difference-in-differences framework applied to household-level panel data combined with FAOSTAT indicators, the analysis compares yield responses of subsidy beneficiaries and non-beneficiaries under contrasting rainfall conditions. Results show that fertilizer subsidies significantly raise maize yields in normal rainfall years but provide limited benefits during drought or excessive precipitation, highlighting the conditional effectiveness of input support.  Cross-country differences reveal that program design, especially targeting efficiency and the timing of subsidy delivery, strongly shapes yield outcomes. The findings emphasize the importance of integrating fertilizer support with climate information services, soil health interventions, and adaptive policy mechanisms. This study contributes empirical evidence for designing climate-smart and context-sensitive subsidy systems aimed at enhancing resilience and food security in East Africa.
