Use these tools to model how water scarcity, fertilizer disruptions, land degradation, climate shocks, import dependency, price spikes, and displacement translate into food loss, calorie deficits, and humanitarian risk.
Designed for NGOs, journalists, researchers, policymakers, and emergency planners. Results are directional estimates for scenario planning—always validate with local datasets when available.
Model the main inputs that shrink food supply—water, fertilizer, land quality, and climate stress.
Estimate production loss from reduced irrigation water and water stress.
Open calculatorModel yield reduction from shortages or price-driven under-application.
Open calculatorEstimate how erosion, salinity, and depleted soils reduce long-term output.
Open calculatorModel yield impact from temperature anomalies and rainfall change.
Open calculatorTranslate shortages into calories, affordability pressure, and population-level risk.
Estimate daily and annual calorie gaps versus minimum dietary needs.
Open calculatorEstimate how many people move into moderate or severe food insecurity.
Open calculatorModel how staple price spikes reduce purchasing power and raise insecurity risk.
Open calculatorExport your assumptions and results for reporting and planning.
View guideIdentify exposure to trade disruption and supply concentration.
Estimate shortage risk and time-to-impact when imported food supply is disrupted.
Open calculatorFor a complete scenario, start with a driver (water/fertilizer/climate/land), convert it to calories, then estimate population at risk and price shock impact. Use import dependency to assess how quickly the situation escalates if supply is disrupted.
Convert need into quantities, duration, and logistics for humanitarian response.
Estimate total food required (tons) for a population across a defined response window.
Open calculatorEstimate daily food needs, monthly tonnage, and water requirements for camp populations.
Open calculatorIf your scenario shows a significant calorie gap or import-risk exposure, you may want implementation models that can replace imported food quickly and efficiently.
If you’re building reports or proposals, these guides help you explain assumptions, cite sources, and communicate results clearly.
If you want, we can build a shared calculator framework so every tool: (1) uses consistent units, (2) exports results, and (3) is easy to expand with country defaults later.
