Mapeamento de culturas permanentes e caracterização do perfil das propriedades rurais no município de Santa Luzia do Pará, Brasil: relatório técnico 01/2024.

Abstract

Monitoring land use through remote sensing represents an important tool for understanding the dynamics of agricultural areas. Although there have been advances in mapping land use and cover, the accuracy of mapping permanent crops is still low for some regions of Brazil. In this work, we used high-resolution images from Maxar (~30 cm) made available by Google to map three permanent crops (citrus, palm oil and black pepper) in the municipality of Santa Luzia do Pará, in the northeast of Pará, for manual delineation. of the polygons of each culture using QGIS software. Based on the Rural Environmental Registry (CAR), we quantified the number of rural properties cultivating each crop. Considering the municipality's Fiscal Module (MF) (75 ha) and CAR information, we classify properties as small (≤ 1 MF), medium (> 1 and ≤ 5 MF) and large properties (> 5 MF). The results indicate a total area of 1,491.5 ha of the three crops, of which: 1,359 ha with oil palm, 98.1 ha with black pepper and 34.4 ha with citrus. In total, we identified 283 rural properties registered in CAR, where 112 produce oil palm, 122 black pepper and 49 citrus. However, 3.3% of the municipality's permanent crop area (48.6 ha) is on properties not registered in the CAR, the majority of which are oil palm (19.5 ha), followed by black pepper (19.0 ha), and citrus (10.1 ha). The information generated in this study can contribute to assisting public and private bodies in decisions about agriculture and environmental regularization in the municipality
