What if you could grow fresh food where it is most needed, cost-effectively reduce heat-related deaths, and create green space for the local community? What if you could also reduce flooding and help mitigate climate change? These questions and more are at the heart of a report on the many possibilities of urban agriculture that the Stanford-based Natural Capital Project (NatCap) is presenting this week to a San Antonio City Council subcommittee.
The report considered two forms of urban agriculture: food forests and urban farms. Food forests are a system of perennial crops – primarily fruit and nuts – planted in layers to mimic a mature ecosystem with plants of differing heights. They are intended to provide food, shade, a haven for pollinators and other wildlife, and to capture water in the landscape. Urban farms typically grow and sell annual mixed vegetable crops, while food forests are primarily perennial orchard crops and tend to be open-access public spaces where people can pick food for free.
A collaboration between NatCap, the Food Policy Council of San Antonio, and three San Antonio city departments (Innovation, Metro Health, and Sustainability), the report estimates the amount of food that could be produced by urban farms and food forests, as well as some of their additional benefits: urban cooling, carbon storage, flood retention, and green space. Anne Guerry, chief strategy officer and lead scientist at NatCap, explained, “Using our model, we took all the publicly owned natural areas in San Antonio and reimagined them from vacant or underutilized lots to farms and food forests. Then, we calculated the benefits that would be provided.”
