Avaliação do uso e ocupação do solo da bacia do Ribeirão Cafezal utilizando ferramenta de classificação temática de imagens

Abstract

The present study aimed to evaluate the evolution of land use and occupation in the Ribeirão Cafezal basin, whose importance is brief for the municipalities of Londrina and Cambé, after all it is one of the main sources of water in the region, responsible for about 40 % of supply. The analysis was carried out based on the creation of land use and occupation charts, with data provided by the MapBiomas platform. The evaluation period used was from 1985 to 2020, separated into 5-year intervals, which revealed an increase in the urban area present in the basin of 11.93%, about 24.61 ha, and a decrease in the rural area by 11 .98%, around 24.71 ha, which suggests a landscape transformation, primarily rural to an urban landscape. Therefore, it is suggested that there is a reassessment of the management measures used in the management of the basin, since the characteristics of occupation, previously exclusively rural, are being changed and replaced by urban aspects and, therefore, the management approaches must adapt to this new reality.
