Resumen
Descripción
This technical report develops a rapid assessment framework for understanding how global shocks transmit into domestic food systems, with particular emphasis on import-dependent economies. Drawing on evidence from the COVID-19 pandemic, the Russia-Ukraine conflict, and recent energy market disruptions linked to tensions in the Strait of Hormuz, the report examines how external shocks spread through interconnected channels including energy and transport costs, trade disruptions, agricultural input markets, and macroeconomic pressures.
The report introduces a structured conceptual framework that explains how shocks move through food systems over time, highlighting short-, medium-, and long-term transmission pathways. It emphasizes that impacts are not uniform and vary depending on market integration, geographic location, commodity type, and the degree of dependence on imported food, fuel, and agricultural inputs.
Using Malawi as an empirical case study, the report applies high-frequency price data to assess early-stage transmission dynamics. The findings show that global energy shocks are reflected immediately in fuel prices and import-dependent commodities such as rice, while domestically produced staples such as maize and beans respond more gradually due to delayed pass-through effects. Rural and poorly integrated markets face higher long-term vulnerability due to elevated transport costs and weaker market connectivity.
The report concludes that strengthening resilience requires integrated policy responses across energy, trade, agriculture, water systems, and social protection, while also highlighting the need for improved market monitoring and early warning systems in vulnerable economies.
