Análise espaço-temporal da Transolímpica e os impactos ambientais em sua zona de influência no município do Rio de Janeiro

Abstract

In 2016, the city of Rio de Janeiro hosted the Olympic Games. To hold this event, the government defined several locations for the competitions, as well as the creation of new routes to facilitate the movement of the public and athletes between these spaces. With the concentration of Olympic facilities in the West Zone of the city, a new expressway was built in that area. The general objective of this research is to investigate the environmental impacts caused by Transolímpica in its zone of direct influence, using geoprocessing techniques such as land cover analysis and the creation of models using the IDRISI software. Public data from the City Hall of Rio de Janeiro, from the years of 2013 to 2019 were collected and analyzed to understand whether the construction of a new road had environmental impacts, mainly in the green areas of the zone of direct influence, in addition to verifying the progress of urbanization after the construction of the road expressed. The results reveal that there are changes in the classes of urbanized areas to the detriment of the vegetation classes, providing important insights into the environmental impacts caused by the construction of the expressway. The data confirmed the environmental impacts in the region, such as the loss of approximately 20% vegetation and the increase of approximately 60% residential areas, indicating the need for measures to be taken by public authorities to balance urban development and conservation of protected areas. This study contributes to Geography and to the city itself as it provides results on the dynamics of land use and discusses the most relevant changes after the road's implementation period, offering an in-depth perspective on the environmental impacts caused by the Transolímpica corridor in the neighborhoods. and in the conservation units around it (zone of influence).
