Core Metrics and Structure
- Diversity: Measures the range of crops, suppliers, or actors in the system. More diversity means less risk if a single crop or supplier fails.
- Redundancy: Tracks the number of alternative pathways (e.g., backup suppliers, routes) available. High redundancy allows the system to reroute or substitute if one part is disrupted.
- Connectivity: Assesses how well different parts of the food system are linked and able to communicate. Strong connectivity supports rapid adaptation and coordination.
- Capital reserves: Refers to backup resources (stockpiles, funds) that can be used during crises.
- Flexibility: The system’s ability to change operations, such as switching suppliers or crops, when faced with disruption.
- Recovery elasticity: How quickly and fully the system can recover after a shock.
- Equity: Ensures that resilience strategies are fair and inclusive, considering vulnerable groups.
Frameworks and Indices
- The Food System Resilience Index (FSRI) breaks down resilience across the food chain: agro-ecological base, producers, processors/supply chains, markets, and infrastructure. Each component is assessed for its pre-shock status, the types of shocks it faces, its resilience capacity, and post-shock outcomes.
- Compound Shock Simulation uses network models and Monte Carlo methods to estimate how the system performs under multiple simultaneous shocks. Metrics like vulnerability concentration (how much is at risk if a few nodes fail), redundancy index, recovery elasticity, and absorptive capacity are visualized.
- The Scorecard rates key attributes (diversity, redundancy, connectivity, capital, preparedness, equity) on a 0-5 scale, highlighting strengths and gaps.
