Mapeamento das propriedades rurais com agricultura permanente no município de Garrafão do Norte- Pa: Relatório Técnico 02/2023.

Abstract

Geotechnologies are key tools for mapping agricultural areas and for studying the dynamics of land use at all scales. However, current large-scale mapping projects with 30m resolution images are still not effective in correctly detecting agricultural areas. In this sense, we aimed to map the cultures of citrus, palm oil and black pepper in the municipality of Garrafão do Norte-PA, through the visual interpretation of high resolution satellite images, identifying the land situation of the producing properties, according to the number of fiscal modules of the municipality. An area of 4,059 ha was mapped with the three crops, citrus in 52% of the planted area (2,109 hectares), followed by 40% with palm oil (1,616 ha), and 8% with black pepper (334 ha). 561 producing properties were identified, of which 47% produce black pepper, 38% citrus and 15% oil palm. Regarding the land situation of the producing properties, a greater number of small rural properties (< 1 MF) grow black pepper (155), followed by citrus (116) and oil palm (56). Among the large properties, the citrus plantation was mapped in 25 properties, black pepper in 22, and oil palm in 9. Of the three crops mapped, only the oil palm crop presented its entire area registered in the CAR, citrus presented 88.1%, and black pepper with 84.6%. The data produced in this work are useful to subsidize public policies for family farming, assist in actions for environmental regularization of properties, and other strategic planning actions for the region.
