Título: Mapeamento de culturas permanentes e caracterização dos imóveis rurais no município de Irituia, Pará, Brasil : relatório técnico 04/2025 Autor(es): ALMADA, Hellen Kezia; CARNEIRO, Francimary da Silva; RODRIGUES, Roner; GONÇALVES, Lorrayne Aparecida; CARDOSO, Luiz Antonio Soares; MARQUES, Eduardo Queiroz; SILVÉRIO, Divino Vicente Abstract: Perennial crops play a significant economic role in the Brazilian market. In the Amazon, the cultivation of oil palm, citrus, and black pepper has grown substantially over the last decade. Despite this, existing land use and land cover maps still fail to efficiently identify these crops in the region. In this study, we used high-resolution satellite imagery to map these three crops in the municipality of Irituia, located in the Northeast Paraense mesoregion, state of Pará, Brazil. Additionally, we quantified the number of rural properties producing each crop based on data from 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). Mapping was performed using Maxar image mosaics (~30 cm resolution) available on Google platforms, with manual delineation of cultivated areas using QGIS software. The results indicated a total of 3,125 hectares of perennial crops in Irituia, of which 49% were citrus (1,533 ha), 47% oil palm (1,472 ha), and only 4% black pepper (120 ha). A total of 401 properties were identified with these crops registered in the CAR, with 199 cultivating citrus, 188 oil palm, and 69 black pepper. Of the total mapped area, 607 ha are located on properties not registered in the CAR, representing 34% of the total citrus area, 22% of the black pepper area, and 4% of the oil palm area. We also assessed the environmental status of these properties. The analysis revealed a total Legal Reserve (RL) deficit of 5,779 ha, of which 2,233 ha must be restored on-site, while 3,546 ha can be legally offset, with sufficient native vegetation available within the municipality to meet this demand. Furthermore, 63% of the Permanent Preservation Areas (APPs) in the municipality show environmental liabilities, with the highest occurrence in oil palm-producing properties. These findings highlight the need for integrated monitoring and restoration strategies, particularly in priority areas for conservation. Overall, the study provides a detailed diagnosis of land use and offers valuable data to support public policies aimed at territorial planning and environmental regularization in the Amazon region.

Título: Mapeamento de culturas permanentes e caracterização dos imóveis rurais no município de Mãe do Rio, no estado do Pará, Brasil: relatório técnico 03/2025 Autor(es): ALMADA, Hellen Kezia; RODRIGUES, Roner; GONÇALVES, Lorrayne Aparecida; CARDOSO, Luiz Antonio Soares; MARQUES, Eduardo Queiroz; SILVÉRIO, Divino Vicente Abstract: The balance between food production and environmental protection is essential for a sustainable future, and this can be achieved through sustainable agricultural practices and land use monitoring. However, land use and land cover mapping technologies still have limitations in identifying permanent crops. In this study, we used high-resolution imagery to map oil palm (Elaeis guineensis), citrus (Citrus sp.), and black pepper (Piper nigrum) cultivation areas in the municipality of Mãe do Rio, located in the northeastern region of Pará State, Brazil. We quantified the number of properties producing each crop based on data from the Cadastro Ambiental Rural (CAR) – the Brazilian Rural Environmental Registry. Properties were classified according to the number of fiscal modules (55 ha each) into small (<1 MF), medium (≥1 and <5 MF), and large (≥5 MF) properties. The mapping was performed using Maxar image mosaics (~30 cm resolution) provided by Google, and the cultivated areas were manually delineated using QGIS software. The results indicated a total of 1,881 ha of mapped permanent crops, with 97% occupied by oil palm (1,829 ha), 2% by citrus (33 ha), and only 1% by black pepper (19 ha). A total of 63 properties registered in the CAR were identified with these crops, of which 13 properties cultivate more than one crop. In total, 37 properties cultivate oil palm, 20 cultivate citrus, and 14 cultivate black pepper. Additionally, 620 ha (33% of the mapped area) are located in properties not registered in the CAR, reinforcing the need for environmental regularization in the region. A comparison with data from the Municipal Agricultural Production of the Brazilian Institute of Geography and Statistics (IBGE, 2023) and Annual Mapping Project of Land Cover and Use in Brazil (MapBiomas) revealed discrepancies among different data sources. High-resolution image mapping indicated a larger planted area than reported by IBGE for oil palm (+31%) and citrus (+9%), while the black pepper area was lower than the official records. In MapBiomas data, more than 90% of the mapped permanent crop areas were classified as pasture, highlighting the limitations in detecting permanent crops. These findings contribute to a better understanding of land use dynamics and provide support for public policies aimed at monitoring and environmental regularization, as well as territorial management and agricultural planning in the region.

Título: Mapeamento de culturas permanentes de dendê, citros e pimenta- do-reino no município de Ipixuna do Pará, Pará, Brasil: relatório técnico 02/2025 Autor(es): CARDOSO, Luiz A. S.; FURTADO, Ademir; GONÇALVES, Lorrayne; MARQUES, Eduardo Q.; ALMADA, Hellen Kezia; OLIVEIRA, Fábio Júnior de; SILVÉRIO, Divino Vicente Abstract: In recent years, there has been significant growth in the agricultural production of permanent crops in the state of Pará, particularly in the municipality of Ipixuna do Pará. However, improvements in the quality of agricultural land mapping have been slow, hindering a deeper understanding of the spatial dynamics of land use. To overcome this limitation and produce more accurate cartographic outputs, we mapped permanent crops (oil palm, citrus, and black pepper) in the municipality through visual interpretation, using high-resolution Maxar satellite imagery. Additionally, we analyzed data from the Rural Environmental Registry (CAR) to characterize the properties where these crops are cultivated. The results revealed that the areas dedicated to these three crops total 3994.66 hectares in the municipality, with 99.99% allocated to oil palm, 0.007% to citrus, and 0.003% to black pepper. Of the oil palm areas, approximately 83% are registered in the CAR, subdivided among small properties (42%), followed by large (21%) and medium (20%) properties. Citrus cultivation is exclusively concentrated on large properties. And the cultivation of black pepper was only verified in areas not registered with CAR. These findings underscore the critical importance of precise mapping of perennial crops for a better understanding of the ongoing agricultural transformations in Brazil. In Ipixuna do Pará, oil palm cultivation predominates on small properties, highlighting the need for public policies that strengthen family farming and recognize its role in local economic development. Oil palm is also cultivated on medium and large properties, whereas citrus and black pepper crops are of minimal relevance in the municipality.

Título: Mapeamento de três culturas permanentes e avaliação do perfil das propriedades rurais no município de São Miguel Pa: relatório técnico 01/2025. Autor(es): PASSO, Fábio B.; OLIVEIRA, Amanda F. de Fábio B.; SOUZA, Francisca M.; CARNEIRO, Francimary; GONÇALVES, Lorrayne A.; MARQUES, Eduardo Q.; EMMERT, Fabiano; SILVÉRIO, Divino Vicente Abstract: The growing demand for food has made land use and occupation very dynamic in the landscape. In this study, we aimed to use high-resolution satellite images to map three permanent crops (citrus, palm oil and black pepper) in the municipality of São Miguel do Guamá and assess the profile of the producing properties based on information from the fiscal module (MF) in the Rural Environmental Registry (CAR). As a result, we identified 101 rural properties producing citrus, 115 black pepper and 61 oil palm. In terms of area, we mapped 2,077 ha for these three crops, with oil palm predominating (70.4%), followed by black pepper (15.3%) and citrus (14.3%). Of these, small and medium-sized properties account for the highest percentage of citrus production with 64.3% and black pepper with 50.5%. Oil palm production is mainly found on large properties (> 5 MF) with 71.2%. For areas without CAR registrations, 10% of the total production area is not in compliance with current legislation, with the highest percentage in black pepper, followed by citrus. Oil palm is fully included in the CAR records. In addition, we identified an area of 1,076.3 ha with some record of environmental liabilities in environmental preservation areas (APPs) in 212 of the 277 producer properties mapped. The mapping carried out here and the results obtained can have various applications for the strategic planning of the productive sector as well as subsidizing public policies for family farming in the region.
