摘      要：The world population will grow up to 9.8 billion by 2050.The intensification in urban growth will occur on all continents and in all sizes of cities,especially in developing countries,experiencing a greater rising in urban agglomerations of 300,000 to 500,000 people,those of 500,000 to 1 million and those of 1 to 5 million,by 2035.In this way,the demand of soil to host human activities(land take)will increase,mainly affecting soils with greater agricultural potential close to cities,at the same time as the need for food will increase.Land rehabilitation can contribute to human food security,to enhance ecosystem services and,if made by waste Technosols,those are viable as substrate for urban agroforestry systems.Although the references for brownfield reclamation for urban agriculture,adding constructed Technosols and de-sealed soils can recover its ecosystem functions even food supply services and would be the solution in urban areas.
