MapBiomas Articles

Here you will find scientific articles prepared by the MapBiomas team. All are involve mapping land use in Brazil. Check out:

 

Rosa et al. - Hidden destruction of older forests threatens Brazil’s Atlantic Forest and challenges restoration programs. Understanding the dynamics of native forest loss and gain is critical for biodiversity conservation and ecosystem services, especially in regions experiencing intense forest transformations. We quantified native forest cover dynamics on an annual basis from 1990 to 2017 in Brazil’s Atlantic Forest. https://advances.sciencemag.org/content/7/4/eabc4547

Souza et al. - Reconstructing Three Decades of Land Use and Land Cover Changes in Brazilian Biomes with Landsat Archive and Earth Engine. In this study, we described a novel approach and the results achieved by a multi-disciplinary network called MapBiomas to reconstruct annual land use and land cover information between 1985 and 2017 for Brazil, based on random forest applied to Landsat archive using Google Earth Engine. https://doi.org/10.3390/rs12172735

Parente et al. - Monitoring the brazilian pasturelands: A new mapping approach based on the landsat 8 spectral and temporal domains. In this study, we utilized the entire set of Landsat 8 images available for Brazil in 2015, from which dozens of seasonal metrics were derived, to produce, through objective criteria and automated classification strategies, a new pasture map for the country.   https://doi.org/10.1016/j.jag.2017.06.003

Fendrich et al. - Disclosing contrasting scenarios for future land cover in Brazil: Results from a high-resolution spatiotemporal model. In this work, we construct a model to evaluate the possible consequences of policy actions on land cover dynamics in the near-future at a high-resolution scale. https://doi.org/10.1016/j.scitotenv.2020.140477

 

Alencar et al - Mapping Three Decades of Changes in the Brazilian Savanna Native Vegetation Using Landsat Data Processed in the Google Earth Engine Platform. The Brazilian Cerrado represents the largest savanna in South America, and the most threatened biome in Brazil owing to agricultural expansion. To assess the native Cerrado vegetation (NV) areas most susceptible to natural and anthropogenic change over time, we classified 33 years (1985–2017) of Landsat imagery available in the Google Earth Engine (GEE) platform. https://doi.org/10.3390/rs12060924

Saraiva et al- Automatic Mapping of Center Pivot Irrigation Systems from Satellite Images Using Deep Learning. In this paper, we propose a method to automatically detect and map center pivot irrigation systems using U-Net, an image segmentation convolutional neural network architecture, applied to a constellation of PlanetScope images from the Cerrado biome of Brazil. Our objective is to provide a fast and accurate alternative to map center pivot irrigation systems with very high spatial and temporal resolution imagery. https://doi.org/10.3390/rs12030558

Parente et al - Next Generation Mapping: Combining Deep  Learning, Cloud Computing, and Big Remote Sensing Data. This study evaluated, based on thousands of PlanetScope images obtained over a 12-month period, the performance of three machine learning approaches (random forest, long short-term memory-LSTM, and U-Net). We applied these approaches to mapped pasturelands in a Central Brazil region.  https://doi.org/10.3390/rs11232881 

Souza, Jr. et al - Long-Term Annual Surface Water Change in the Brazilian Amazon Biome: Potential Links with Deforestation, Infrastructure Development and Climate Change. In this study, we present a long-term spatiotemporal analysis of surface water annual change and address potential connections with deforestation, infrastructure expansion and climate change in this region. https://doi.org/10.3390/w11030566

Rosa, Marcos R - Comparação e análise de diferentes metodologias de mapeamento da cobertura florestal da Mata Atlântica. The differences found in the products point to distinct and complementary uses, with the Atlas base most suitable for identifying deforestation and analyzing biodiversity conservation and MapBiomas for analysis of fragmentation, restoration and water protection. The option for the product that will be used varies according to the objective of the proposed work. http://www.agb.org.br/publicacoes/index.php/boletim-paulista/article/view/658

Costa et al - Novas tecnologias e sensoriamento remoto: aplicação de uma oficina didática para a disseminação das  potencialidades dos produtos e ferramentas do MapBiomas. This work aimed to report the experiences of the application of a didactic workshop that dealt with the potential of the products and tools of the Mapbiomas Project in a class of the Graduate Program in Modeling in Earth and Environmental Sciences, from the State University of Feira de Santana. http://dx.doi.org/10.7770/safer-V0N0-art1402

Parente et al - Assessing the pasturelands and livestock dynamics in Brazil, from 1985 to 2017: A novel approach based on high spatial resolution imagery and Google Earth Engine cloud computing. This work has mapped, annually and in an unprecedented way, the totality of the Brazilian pastures, from 1985 to 2017. With an overall accuracy of about 90%, the 33 maps produced indicated the pasture area varying from ~118 Mha ±3.41% (1985) to ~178 Mha ±2.53% (2017), with this expansion occurring mostly in the northern region of the country and to a lesser extent in the midwest. https://doi.org/10.1016/j.rse.2019.111301

Leandro Parente and Laerte Ferreira - Assessing the Spatial and Occupation Dynamics of the Brazilian Pasturelands Based  on the Automated Classification of MODIS Images from 2000  to 2016. This study mapped, through objective criteria and automatic classification methods (Random Forest) applied to MODIS (Moderate Resolution Imaging Spectroradiometer) images, the totality of the Brazilian pastures between 2000 and 2016.  https://doi.org/10.3390/rs10040606

Mas et al - Analysis of High Temporal Resolution  Land Use/Land Cover Trajectories. In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. https://doi.org/10.3390/land8020030

Diniz et al - Brazilian Mangrove Status: Three Decades of SatelliteData Analysis. This manuscript presents a Google Earth Engine (GEE)-managed pipeline to compute the annual status of Brazilian mangroves from 1985 to 2018, along with a new spectral index, the Modular Mangrove Recognition Index (MMRI), which has been specifically designed to better discriminate mangrove forests from the surrounding vegetation. If compared separately, the periods from 1985 to 1998 and 1999 to 2018 show distinct mangrove area trends. https://doi.org/10.3390/rs11070808
