Urban Farm DB summary
Using GIS grid-cell analysis, the study quantified vegetable-weight and key-nutrient self-sufficiency for each land-use pattern in Tokyo, showing how mixed agricultural and urban land uses contribute to resilience. Tokyo's fruit-and-vegetable self-sufficiency was estimated at 4.27% currently with a potential of 11.73%.
Key points
- 1Tokyo's current fruit and vegetable self-sufficiency is 4.27%, with a potential to reach 11.73%.
- 2Nutritional self-sufficiency for selected nutrients was highest for vitamin K (6.54%), followed by vitamin C (3.84%) and vitamin A (1.92%).
- 3Peri-urban areas demonstrated the highest resilience against aggregated risks and population density due to their mixture of agricultural and urban land uses.
- 4The study proposed a methodology using GIS spatial grid cell analysis to identify patterns of agricultural production and quantify self-sufficiency rates in urban areas.
- 5Analysis of 1479 grid cells and 49,263 agricultural plots in Tokyo led to the categorization of six distinguishable land use patterns.

Abstract and stored text
OpenAlexUrban agriculture can enhance the resilience of neighborhoods by providing fresh food in times of natural disasters; however, there is little empirical evidence to support this. Therefore, this study proposes a methodology to identify patterns of agricultural production in urban areas by quantifying self-sufficiency rates in vegetable weight and key nutrients. A spatial grid cell analysis using a geographic information system (GIS) identifies the current and potential self-sufficiency of each land use pattern in Tokyo. In a total of 1479 grid cells, the dominant land use and locations of 49,263 agricultural plots led to the categorization of six distinguishable land use patterns. The results showed that Tokyo has a fruit and vegetable self-sufficiency of 4.27% and a potential of 11.73%. The nutritional self-sufficiency of selected nutrients was the highest in vitamin K (6.54%), followed by vitamin C (3.84%) and vitamin A (1.92%). Peri-urban areas showed the highest resilience in relation to aggregated risks and population density because of the mixture in agricultural and urban land uses.
Why it matters for urban farming
This study empirically demonstrates the crucial role of urban agriculture in providing food during disasters and enhancing urban resilience. It specifically highlights that areas with mixed urban and agricultural land uses exhibit higher resilience against aggregated risks. For citizen-driven urban farms, this provides strong evidence that their activities contribute not only to food production but also to community security and sustainability. It also suggests the importance of maintaining and integrating agricultural spaces in urban planning, offering concrete justification for expanding urban farming initiatives and contributing to local food self-sufficiency.
