Análise de dados sobre solos do bioma cerrado

Abstract

Soil is a fundamental natural resource for ecosystems and society, performing essential functions such as nutrient supply, carbon storage, water regulation, and biodiversity support. The availability of reliable soil information is crucial for research, sustainable management, and the formulation of effective public policies. This study aimed to evaluate the availability and quality of soil data for the Cerrado Biome, using the Brazilian SoilData repository as the main source, complemented by land use and land cover information from MapBiomas. A total of 2,280 sampling points were analyzed, considering their spatial distribution, predominant soil types (Oxisols, Neosols, and Plinthosols), and their relationship with structural provinces and geological characteristics. The analysis revealed a strong concentration of samples in agricultural areas and lower representation in regions of native vegetation, such as savannas and forests, indicating information gaps that hinder a full understanding of the biome’s environmental heterogeneity. Clear patterns were identified, including the prioritization of agricultural areas, the impact of anthropogenic pressure on soils, and a tendency toward reduced recent data sharing, which limits the updating of national databases. The integration of geographic, pedological, and environmental data was performed through the compilation and assimilation of these datasets, enabling the identification of land-use patterns, human impacts, and conservation trends. The results highlight the importance of data curation and standardization, as well as data sharing in open repositories, to support sustainable management practices, environmental conservation, biodiversity preservation, and agricultural development. The analysis reinforces that the use of integrated and high-quality data contributes to scientific research, territorial planning, and evidence-based decision-making, promoting the sustainability of the Cerrado in the face of anthropogenic pressures and climate change.
