Mapeamento de culturas permanentes e caracterização os imóveis rurais no município de Aurora do Pará, Brasil: Relatório Técnico 04 /2023.

Abstract

The monitoring of land use through geotechnology constitutes an important tool for understanding the dynamics of agricultural areas. Despite the great advances in the automation of surface use and coverage mappings, the quality of these automated mappings is still not accurate enough to detect some crops in certain regions of Brazil. In this work, high-resolution images were used to map citrus, oil palm, and black pepper crops in the municipality of Aurora do Pará, northeastern Pará state. Additionally, we quantified the number of properties producing these crops based on the Rural Environmental Registry (CAR), and considering the fiscal module (MF) of the municipality (55 ha), we classified the properties as small (≤1 MF), medium (>1 and ≤5 MF) and large (>5 MF) properties. For mapping, we used Maxar images that are made available by Google. We manually delineated the polygons of each plantation through QGIS software. The results show a total area of 2,105.85 ha for the three crops, being: 1984.63 ha of this area with oil palm, 72.8 ha with black pepper and 78.8 ha with citrus. In total, we identified 418 registered producers in CAR. Of this total, 264 are oil palm producers, 85 are black pepper producers and 69 are citrus producers. However, 65.39% of permanent crops in the municipality (1377 ha) are not registered in CAR. Of these unregistered areas, 69% have oil palm planting, 20% have citrus and 5% have black pepper. We believe that the information generated in this study can contribute to the training of civil society, public and private organizations regarding decision-making in agricultural management with responsibility and sustainability
