Why food system needs this combination of methods.
Food risk runs from soils and weather to diets, so the method mix spans agricultural science and ecology for production, Earth observation and spatial statistics for where it happens, forecasting for when, econometrics for prices, and optimisation for how scarce supply is allocated. Hydrology and environmental engineering link it to water.
Grounding makes claims checkable.
When a finding names the methods it depends on, a reader can see its assumptions and limits, and an expert in that method can challenge it.
