Land recycling, food security and Technosols

Urban Farm DB summary

This paper argues, without presenting new primary data, that as world population grows toward a projected 9.8 billion by 2050 and urban agglomerations expand across all continents by 2035, competition for land near cities with high agricultural potential will intensify; it proposes that land rehabilitation using constructed Technosols on brownfield sites and de-sealed soils can recover ecosystem functions, including food-supply services, as a substrate for urban agroforestry.
