Análise espaço - temporal da evolução de assentamentos humanos no município de Chimoio entre 1993 e 2023

Abstract

This study examines the spatiotemporal dynamics of human settlement evolution in the municipality of Chimoio, Manica Province over a period of 3 decades, from 1993 to 2023. Using a combination of Remote Sensing, Geographic Information Systems (GIS) and socioeconomic data analysis, the research aims to understand the patterns, changes in land use and land cover, and the areas that have undergone changes due to the expansion of human settlements and the factors that have driven the rapid expansion across the municipality. The methodology employed in the study involved the analysis of multiple data satellite images, complemented by census data and documentary research. Supervised classification techniques were applied to map changes in land use and land cover with a primary focus on the expansion of built-up areas. The classification solution was evaluated using accuracy and Kappa index. An analysis of data from 1993 to 2023 reveals a significant expansion of urban and semi-urban areas in the study region. Urban settlements have shown steady growth, increasing from 1.68 km2 in the decade 1993-2003 to 7.17 km2 in 2013-2023, resulting in a total gain of 10.82 km2 over the 3 decades studied. The rapid expansion of human settlements in the municipality of Chimoio between 1997 and 2017 is the result of a confluence of demographic and socio-economic factors. The high fertility rate, combined with dynamic migration patterns and the economic attractiveness of the city, has created an environment conducive to accelerated urban growth(TRADUÇÃO NOSSA)
