Climate Change Adaptation in African Vegetable Farming Systems

Research on climate change adaptation in vegetable farming systems in Africa has predominantly focused on West and East Africa, with limited studies in Central and Northern Africa. This geographical imbalance is reflected in the global adaptation dataset, which indicates a significant gap in adaptation research in these regions. Between 2014 and 2018, West and East Africa received the majority of adaptation-related funding, while Northern, Central, and Southern Africa collectively received less than US$0.8 billion annually, experiencing a decline in funding in 2018. The disparity in research and funding is attributed to differences in adaptation finance, research capacity, and the historical concentration of international partnerships, such as those with the Consultative Group on International Agricultural Research (CGIAR) and the United States Agency for International Development (USAID).

Despite the rapid urbanization in developing countries, research on urban and peri-urban agricultural systems in Africa remains limited. These systems are critical for addressing food security and climate resilience, yet adaptation efforts have primarily focused on rural contexts. The urgency of building resilient urban food systems is emphasized, as many African cities lack the institutional frameworks necessary for sustainable urban food systems. Integrating adaptation research into urban governance is essential for enhancing cities' capacity to tackle food system challenges posed by climate change.

Adaptation efforts in African vegetable farming systems have largely concentrated on water-related hazards, while non-water-related challenges, such as soil degradation and pest outbreaks, are increasingly significant. The interplay of multiple hazards, including extreme temperatures and droughts, complicates adaptation efforts and remains underexplored in current literature. Most adaptation strategies are technology-driven and incremental, focusing on modifying existing practices rather than transformative changes. Institutional adaptation is limited, hindered by financial constraints, political inertia, and insufficient understanding of climate risks.

The private sector's involvement in adaptation efforts is notably minimal, with a lack of engagement from businesses in the vegetable sector. This absence reflects perceived low returns on investment and inadequate enabling policies. Small and medium-sized enterprises (SMEs) could play a crucial role in scaling up adaptation efforts by providing financial and technical resources. However, the necessary mechanisms to support private sector participation, such as risk advisory services and insurance products, are often lacking in developing countries.

Current adaptation frameworks often prioritize efficiency and utilitarian indicators, such as increased yield and income gains, while neglecting the perspectives of local communities. This approach raises concerns about the social justice implications of adaptation strategies, as they may reinforce existing vulnerabilities rather than address root causes. Future research should focus on how local communities define their success in adapting to climate change, ensuring that adaptation assessments align with their lived experiences and aspirations.

The review highlights critical gaps in adaptation research and policy for vegetable farming systems in Africa, particularly in urban contexts. Addressing these gaps requires equitable investment in research and capacity-building initiatives across regions. Future efforts should emphasize interdisciplinary approaches that integrate community perspectives and prioritize social equity in adaptation strategies. By fostering a more inclusive and comprehensive understanding of adaptation, stakeholders can better support the resilience of African vegetable farming systems in the face of climate change.
