Urban and peri-urban agriculture in Goiânia: The search for solutions to adapt cities in the context of global climate change

Abstract

Goiânia is a city in the late 1930s, and one of the two cities constructedin the Brazilian savannah. In 2018, it had 1.4 million inhabitants and 2,05217 inhabitantsper km2. With less than 100 years of age, the urbanization model associated with the effects of global climate change has led the city to live, in recent periods, with moments of water scarcity and flooding. In view of this, the urban municipal policy seeks to point out actions that aim to control land use and occupation from an environmental sustainability perspective. Urban and peri-urban agriculture (UPA) is one strategy and will be the main objective of this article. The urban municipal policy will indicate areas for the practice of UPA as a strategy for adapting cities in the context of climate change. As a secondary objective, the potential for carbon sequestration by this activity was analyzed. The methodology was based on the analysis of urban land use in a Geographic information system (GIS) environment. The database of the Municipality of Goiânia was used. The results indicated three levels of priorities, with a total of 10,650 hectares. In terms of carbon sequestration , this area would result in the capture of 5.536.764,60 tons of CO2 from the atmosphere in 20 years.
