Avaliação do indicador de desenvolvimento sustentável associado à degradação do solo no estado do Paraná

Abstract

SDG 15 aims to protect, recover and promote the sustainable use of terrestrial ecosystems, one of its goals, 15.3 deals more specifically with combating soil degradation. Indicator 15.3.1 objectively measures goal 15.3, separating it into three sub-indicators: Productivity, Soil Cover, and Soil Organic Carbon. Using remote sensing images, which can be applied in large-scale areas. This paper aims to estimate indicator 15.3.1 for the state of Paraná. For this, data from the AVHRR/GIMMS and MD13Q1-coll6 sensors were used, in addition to data series such as the ESA CCI, which has information on land use and land cover, and SoilGrids, which presents data from digital soil mapping. With the free geographic information system QGIS, maps of degradation, improvement and stability were generated for each of the sub-indicators, using the trends.earth plug-in. The parameters were combined in a "one out, all out" manner, which means that, if one sub-indicator is considered degraded, the indicator is considered degraded for that point, generating the map of indicator 15.3.1. From the index it was detected that most of the state of Paraná is either stable or improving, with an alert to the mesoregions of Centro Ocidental Paranaense, Norte Central Paranaense, Sudoeste Paranaense, Sudeste Paranaense and Noroeste Paranaense, which mostly have areas that were considered degraded.
