Household coping strategies and food security in the multi-shock environment of Mali

Household coping strategies and food security in the multi-shock environment of Mali

This study investigates household coping strategies and food security outcomes within the context of multiple, overlapping shocks, including conflict, food price volatility, climate events, and economic instability. Utilizing a unique household dataset on Mali combined with probit models to account for the compounded effects of these systemic shocks, the analysis highlights significant elasticities between specific shocks and household responses. Key findings demonstrate that while preventive measures, such as income diversification, strengthen resilience, reactive strategies like selling productive assets or borrowing money or food provide only short-term relief but undermine long-term sustainability. The impact of coping strategies on food security measures, including the Food Consumption Score (FCS), Household Dietary Diversity Score (HDDS), and Household Hunger Scale (HHS), reveals the trade-offs Malian households make between immediate needs and future stability. The study emphasizes the critical role of policy interventions in mitigating these vulnerabilities, including strengthening social safety nets, expanding access to financial services, and promoting climate-resilient agricultural practices. By integrating the analysis of multiple shocks, this research provides actionable insights for building household and community resilience in environments of compounded risk.

The case for food system knowledge support system (FS-KSS)

2025Ulimwengu, John M.; Mutyasira, Vine; Keizire, Boaz

The case for food system knowledge support system (FS-KSS)

The Comprehensive Africa Agriculture Development Programme (CAADP) Strategy and Action Plan (2026-2035) is a key framework aimed at transforming Africa’s agrifood systems to achieve sustainable agricultural growth, food security, and economic development across the continent. Building on the lessons from the Malabo Declaration, the Plan emphasizes the need for sustainable food production, inclusivity, and resilience in the face of climate change and other challenges. However, achieving these ambitious goals requires a robust and integrated support system that can provide accurate, real time data, facilitate evidence-based decision-making, and promote accountability among stakeholders. Without a well-functioning knowledge system, the efforts to transform agrifood systems may be hindered by data gaps, limited analytical capacity, and a lack of coordination among various actors. The effectiveness of food systems in Africa is often hindered by data gaps, inconsistencies, and limited capacity for data analysis. These issues compromise the ability of governments and other stakeholders to make informed decisions, implement sound policies, and monitor progress toward national and continental goals such as food security and climate resilience. This is where the Food System Knowledge Support System (FS-KSS) becomes crucial, as it provides the necessary tools to ensure effective implementation of the CAADP Strategy and Action Plan.

The case for post Malabo Agenda implementation guidelines

The case for post Malabo Agenda implementation guidelines

The Comprehensive Africa Agriculture Development Programme (CAADP), developed by the African Union (AU) in 2003, marked a significant turning point for Africa’s agricultural development. CAADP’s objective was to transform agriculture into a key driver of economic growth, poverty reduction, and food security across the continent. Through a focus on increasing agricultural productivity and ensuring that agricultural development was aligned with national and regional priorities, CAADP sought to tackle Africa’s persistent challenges of hunger, malnutrition, and economic stagnation. In 2014, the Malabo Declaration was introduced as the second phase of CAADP implementation, with a new set of ambitious targets aimed at ending hunger and halving poverty by 2025. The declaration reinforced the importance of agricultural-led growth and committed African governments to specific goals, including increasing agricultural productivity by at least 6% annually and allocating at least 10% of national budgets to agriculture. It also emphasized sustainable agriculture, resilience to climate change, and equitable access to resources, particularly for women and smallholder farmers.
