Analysis of changes in the land use and coverage in two parks and its surroundings in Campo Grande, Mato Grosso do Sul

Abstract

Urban parks are an important element in the composition of the urban landscape, with ecological, aesthetic and social functions. However, these environments are subject to human pressure, threatening their stability. For these reasons, the objective was to analyze land use and land cover and the Normalized Difference Vegetation Index (NDVI) in two State Parks (Prosa and Matas do Segredo) located in the urban area of Campo Grande, Mato Grosso do Sul. Landsat TM 5 and OLI 8 and, Sentinel 2^a MSI images, in 1985, 2000, 2014 and 2020 years were used and evaluated using geotechnology procedures. The results obtained indicate that the parks present problems related to the lack of effectiveness of the management plans, with anthropized areas existing within the limits of the UCs. In addition, the buffer zones that should mitigate the anthropic impacts that the parks suffer are pressure agents, as they do not have adequate management, with continuous removal of native vegetation cover for different uses, also portraying problems related to management plans. On the other hand, the NDVI demonstrated the resilience of the environment, indicating gains in quality in the plant structure that become more complex. The results obtained indicate that despite the problems, the parks have good vegetation quality and the fulfillment of one of their functions, the conservation of natural resources, in addition to providing better environmental conditions to the communities in their surroundings and the city.
