Resilience to abrupt global catastrophic risks disrupting trade: Combining urban and near-urban agriculture in a quantified case study of a globally median-sized city
Fig 2
Crop optimization results: Crops requiring least land area to feed one person - different agriculture types and post-catastrophe climate scenarios.
The figure shows the minimum land area required to feed one person in both the normal climate scenario (top panel) and nuclear winter scenario (bottom panel – only frost-resistant crops considered), whether deploying urban agriculture methods (UA) or near-urban industrial agricultural methods. Only the crops/crop combinations found to require the least and next least land area are displayed. Shorter bars in the graph indicate less land is required to provide protein and food energy needs (i.e., most optimal crops). Yields in the nuclear winter scenario are typical yields of frost-resistant crops and not adjusted here for reduced sunlight (see Table 3 for such an adjustment). GCR – global catastrophic risk; UA – urban agriculture.
