Urban Farm DB summary

This study evaluated the role of urban agriculture (UA) in enhancing post-disaster food security in Wellington, New Zealand, a region highly prone to earthquakes. It calculated vegetable self-sufficiency by mapping potential productive land, estimating vegetable yields, and assessing post-disaster food demands across multiple scenarios. Potential productive land accounted for 0.3% to 1.5% of the total area, primarily distributed in the eastern part of the city. Results indicate that Wellington's vegetable self-sufficient rates through UA range from 3% to 75%, with higher rates for displaced and vulnerable populations. Realizing this potential will require stronger policy support and integration with urban planning and disaster preparedness.
