A prominent goal of policies mitigating climate change and biodiversity loss is to achieve zero deforestation in the global supply chain of key commodities, such as palm oil and soybean. However, the extent and dynamics of deforestation driven by commodity expansion are largely unknown. Here we mapped annual soybean expansion in South America between 2000 and 2019 by combining satellite observations and sample field data. From 2000 to 2019, the area cultivated with soybean more than doubled from 26.4 Mha to 55.1 Mha. Most soybean expansion occurred on pastures originally converted from natural vegetation for cattle production. The most rapid expansion occurred in the Brazilian Amazon, where soybean area increased more than tenfold, from 0.4 Mha to 4.6 Mha. Across the continent, 9% of forest loss was converted to soybean by 2016. Soybean-driven deforestation was concentrated at the active frontiers, nearly half located in the Brazilian Cerrado. Efforts to limit future deforestation must consider how soybean expansion may drive deforestation indirectly by displacing pasture or other land uses. Holistic approaches that track land use across all commodities coupled with vegetation monitoring are required to maintain critical ecosystem services. Deforestation is often driven by land conversion for growing commodity crops. This study finds that, between 2000 and 2019, most soybean expansion in South America was on pastures converted originally for cattle production, especially in the Brazilian Amazon. More soy-driven deforestation occurred in the Brazilian Cerrado.

O objetivo deste estudo foi a geração de modelos de volume comercial com casca (Vcc) em povoamentos de Eucalyptus dunnii e urograndis em diferentes estágios de crescimento e condições de sítio, utilizando dados de reflectância das diferentes regiões do espectro eletromagnético e de índices de vegetação. As regressões lineares múltiplas geradas resultaram em três modelos preditivos, sendo que os mais significativos, em ordem decrescente foram para as espécies de Eucalyptus dunnii e Eucalyptus urograndis com 50 e 59 meses de idade, respectivamente, seguido pelo modelo para Eucalyptus urograndis de 25 meses, apesar da equação de regressão para Eucalyptus dunnii de 34 meses, não tenha sido significativa. O índice de vegetação ajustado ao solo (SAVI 0,5) mostrou-se relevante na construção dos três modelos, pelos diferentes graus de contribuição da componente solo, decorrente do não fechamento das copas em povoamentos jovens de diferentes idades. A região do infravermelho de ondas curtas (SWIR 1) também compôs os modelos de Eucalyptus dunnii e Eucalyptus urograndis, analisados conjuntamente e o modelo preditivo para Eucalyptus dunnii, demonstrando a importância da estrutura do dossel florestal por esta região do espectro eletromagnético estar relacionada ao aumento do conteúdo de lignina e em decorrência da evolução de sua capacidade produtiva.

Land cover is an important descriptor of the earth’s terrestrial surface. It is also crucial to determine the biophysical processes in global environmental change. Land-use change showcases the management of the land while revealing what motivated the alteration of the land cover. The type of land use can represent local economic and social benefits, framed towards regional sustainable development. The Amazon stands out for being the largest tropical forest globally, with the most extraordinary biodiversity, and plays an essential role in climate regulation. The present work proposes to carry out a bibliometric analysis of 1590 articles indexed in the Scopus database. It uses both Microsoft Excel and VOSviewer software for the evaluation of author keywords, authors, and countries. The method encompasses (i) search criteria, (ii) search and document compilation, (iii) software selection and data extraction, and (iv) data analysis. The results classify the main research fields into nine main topics with increasing relevance: ‘Amazon’, ‘deforestation’, ‘remote sensing’, ‘land use and land cover change’, and ‘land use’. In conclusion, the cocitation authors’ network reveals the development of such areas and the interest they present due to their worldwide importance.

Aquaculture and salt-culture are relevant economic activities in the Brazilian Coastal Zone (BCZ). However, automatic discrimination of such activities from other water-related covers/uses is not an easy task. In this sense, convolutional neural networks (CNN) have the advantage of predicting a given pixel’s class label by providing as input a local region (named patches or chips) around that pixel. Both the convolutional nature and the semantic segmentation capability provide the U-Net classifier with the ability to access the “context domain” instead of solely isolated pixel values. Backed by the context domain, the results obtained show that the BCZ aquaculture/saline ponds occupied ~356 km2 in 1985 and ~544 km2 in 2019, reflecting an area expansion of ~51%, a rise of 1.5× in 34 years. From 1997 to 2015, the aqua-salt-culture area grew by a factor of ~1.7, jumping from 349 km2 to 583 km2, a 67% increase. In 2019, the Northeast sector concentrated 93% of the coastal aquaculture/salt-culture surface, while the Southeast and South sectors contained 6% and 1%, respectively. Interestingly, despite presenting extensive coastal zones and suitable conditions for developing different aqua-salt-culture products, the North coast shows no relevant aqua or salt-culture infrastructure sign.

In the 1990s and 2000s, soybean farming grew sharply, particularly in states located in Brazil’s mid-west region. To curb deforestation, the Federal Government implemented command and control policies and, at the same time, soy-buying companies and Civil Society Organizations implemented the Soy Moratorium. This paper focused on the major role of these initiatives in decreasing soybean farming in areas deforested after 2006 and their importance in achieving this result. We considered rich database deforestation, and soybean planted area based on highly detailed remote sensing images, combined with explanatory variables of different sources, forming a panel data of 287 municipalities over 8 years. Spatial panel data models are implemented to avoid any spatial correlation problems and to analyze relationships through regional units and time. The results confirm that lower deforestation rates in the biome laid the foundation for reducing soybean farming in the Amazon biome. However, since 2008, when the Soy Moratorium was launched, there was a structural decline in this relationship that was decisive for a decoupling of soybean farming from deforestation. Therefore, government programs to reduce deforestation made room for a new environment for agricultural expansion in line with Brazilian law and environmental commitments. The Soy Moratorium reinforced this new order, and this production chain became a case study on public and private governance, given its importance in reducing soybean farming in deforested areas after the cut-off date. These public and private effects stress the importance of coordinated actions to achieve efficient results, especially in a large social and environmentally complex region as the Brazilian Amazon, to halt biodiversity degradation and increase participation in value added markets.

The Ecuadorian Amazon is considered a biodiverse region, and at the same time contains the largest number of oil blocks and oilfields in the country. Oil exploitation requires the implementation of oil facilities and related infrastructure, such as roads, water, and energy supply, for operation. These large engineering works can alter the dynamics of the Amazonian natural ecosystems. This paper analyzes the land use and land cover (LULC) change and relates spatial patterns within an oil block located in the province of Orellana, Ecuador. The study was processed in two phases, the first corresponding to the collection and classification of LULC classes within the oil block. The second phase concerned the calculation of landscape metrics, with the purpose of quantitatively characterizing each class. This analysis was carried out for the pre-concession, post-concession scenarios of the oil block and the current scenario of the region. The results revealed that the low predominance of forest cover within the study region is not directly associated with the beginning of the Block 47 concession. On the other hand, a significant reduction of the Coca River was evidenced for the 2018 scenario.

Tropical secondary forests sequester carbon up to 20 times faster than old-growth forests. This rate does not capture spatial regrowth patterns due to environmental and disturbance drivers. Here we quantify the influence of such drivers on the rate and spatial patterns of regrowth in the Brazilian Amazon using satellite data. Carbon sequestration rates of young secondary forests (<20 years) in the west are ~60% higher (3.0 ± 1.0 Mg C ha−1 yr−1) compared to those in the east (1.3 ± 0.3 Mg C ha−1 yr−1). Disturbances reduce regrowth rates by 8–55%. The 2017 secondary forest carbon stock, of 294 Tg C, could be 8% higher by avoiding fires and repeated deforestation. Maintaining the 2017 secondary forest area has the potential to accumulate ~19.0 Tg C yr−1 until 2030, contributing ~5.5% to Brazil’s 2030 net emissions reduction target. Implementing legal mechanisms to protect and expand secondary forests whilst supporting old-growth conservation is, therefore, key to realising their potential as a nature-based climate solution.

Global-scale forest/non-forest (FNF) maps are of crucial importance for applications like biomass estimation and deforestation monitoring. Global FNF maps based on optical remote sensing data have been produced by the wall-to-wall satellite image analyses or sampling strategies. The German Aerospace Center (DLR) and the Japan Aerospace Exploration Agency (JAXA) also made available their global FNF maps based on synthetic aperture radar (SAR) data. This paper attempted to answer the following scientific question: how comparable are the FNF products derived from optical and SAR data? As test sites we selected the Amazon (tropical rainforest) and Cerrado (tropical savanna) biomes, the two largest Brazilian biomes. Forest estimations from 2015 derived from TanDEM-X (X band; HH polarization) and ALOS-2 (L band; HV polarization) SAR data, as well as forest cover information derived from Landsat 8 optical data were compared with each other at the municipality and image sampling levels. The optical-based forest estimations considered in this study were derived from the MapBiomas project, a Brazilian multi-institutional project to map land use and land cover (LULC) classes of an entire country based on historical time series of Landsat data. In addition to the existing forest maps, a set of 1619 Landsat 8 RGB color composites was used to generate new independent comparison data composed of circular areas with 5-km diameter, which were visually interpreted after image segmentation. The Spearman rank correlation estimated the correlation among the data sets and the paired Mann–Whitney–Wilcoxon tested the hypothesis that the data sets are statistically equal. Results showed that forest maps derived from SAR and optical satellites are statistically different regardless of biome or scale of study (municipality or image sampling), except for the Cerrado´s forest estimations derived from TanDEM-X and ALOS-2. Nevertheless, the percentage of pixels classified as forest or non-forest by both SAR sensors were 90% and 80% for the Amazon and Cerrado biome, respectively, indicating an overall good agreement.

Este estudo teve como objetivo identificar a dependência espacial das taxas de detecção de hanseníase na população geral e em menores de 15 anos com a proporção de migração, no estado do Pará. Foi realizada pesquisa com desenho de estudo ecológico em uma série histórica de casos de novos de hanseníase, entre os anos de 2006 a 2015, a partir de do banco de dados do Sistema de Informação de Agravos Notificáveis do Ministério da Saúde, referentes ao Estado. A evolução temporal da taxa de detecção geral, padronizada pela idade, apresentada geograficamente, identificou um corredor de muito hiperendemicidade, no sentido Sudoeste-Sudeste do Estado e dois aglomerados de municípios, também de muito hiperendemicidade, na fronteira com os estados do Tocantins e do Maranhão. A análise espacial demonstrou que as taxas médias na população em geral e em menores de 15 anos e a proporção de migração apresentaram autocorrelação espacial positiva, permitindo identificar clusters localizados nas áreas Sudeste, Sudoeste, Centro Norte e Nordeste do Estado. Nessas áreas estão concentrados os projetos de exploração mineral e de agropecuária e foram construídas duas Usinas Hidroelétricas nas décadas de 1960 e 2000, sendo favorecidas por rede viária e ferroviária consolidada que é usada para o escoamento dos produtos e para o intenso fluxo migratório das pessoas. Esta pesquisa evidencia que a hanseníase apresenta alta magnitude com característica de transmissão e que os 2/3 da área territorial que expressam hiperendemicidade, a destacando como sério problema de saúde pública no estado do Pará.

O estudo foi conduzido na bacia hidrográfica do Rio Marapanim, localizada na região Nordeste do estado do Pará e se propôs a realizar a partir de análise das transformações da paisagem por meio de técnicas de sensoriamento remoto e geoprocessamento e modelagem dinâmica a fim de entender os processos atuais e refletir acerca do futuro. Foram construídos modelos dinâmicos através da utilização do arcabouço de modelagem LuccME, desenvolvido pelo Centro de Ciência do Sistema Terrestre (CCST) do Instituto Nacional de Pesquisas Espaciais (INPE) e colaboradores a fim de representar computacionalmente as mudanças de uso da terra e seus fatores determinantes. Foram feitas simulações para o período de 2008-2017. Os resultados revelam que os dados de entrada disponíveis, a dependência espacial entre usos da terra e a complexidade da área de estudo, os modelos gerados mostraram um desempenho aceitável para alocar uma demanda que possibilitasse o ajuste espacial, bem como a validação para o período analisado de todas as variáveis dependentes em um mesmo processo. Recomenda-se que a partir desta pesquisa sejam realizados outros modelos de simulação, com base na geração de cenários por meio de modelagem dinâmica espacial com a integração de planos de gestão territorial e os dados gerados podem auxiliar na formulação de políticas públicas. Factors that influence land use modeling of the Marapanim River watershed, Pará A B S T R A C TThe study was conducted in the Marapanim River basin, located in the Northeast region of the state of Pará. We aimed to analyze the processes that trigger landscape transformations and promote a reflection on scenarios for the basin. For this, we used remote sensing, geoprocessing and dynamic modeling techniques. We constructed dynamic models through the LuccME modeling framework. To computationally represent changes in land use and it determining factors, through simulations for the period 2008-2017. The basin presents a state of advanced forest fragmentation and there are impacts on the water regime considering the current land use and cover classes. The few remnants of forest present in the basin area are being converted to agricultural and forestry activities. In addition to this scenario of plant suppression, forest fragmentation causes habitat fragmentation and biodiversity loss. The generated models, considering the available input data, the spatial dependence between land uses, and the complexity of the study area, showed an acceptable performance to allocate a demand that would enable spatial adjustment, as well as validation for the analyzed period of all dependent variables in the same process. It recommended that from this research. other simulation models be performed based on the generation of scenarios through spatial dynamic modeling with the integration of territorial management plans, and the data generated can help in the formulation of public policies.Keywords: Watershed.

The expansion of hydroelectric dams that is planned, and under construction, in the Amazon basin is a proposal to generate “clean” energy, with the purposes of meeting the regional energy demand, and the insertion of Brazil into the international economic market. However, this type of megaproject can change the dynamics of natural ecosystems. In the present article, the spatiotemporal patterns of deforestation according to distance from the reservoir in the vicinity of the lake of Tucuruí, and within a radius of 30 km from it, are analyzed. A linear spectral mixture model of segmented Landsat-thematic mapper (TM), enhanced thematic mapper plus (ETM+), and operational land imager (OLI) images, and proximity analysis were used for the mapping of the land-cover classes in the vicinity of the artificial lake of Tucuruí. Likewise, landscape metrics were determined with the purpose of quantifying the reduction of primary forest, as a mechanism of loss of ecosystem services in the region. These methods were also used for the evaluation of the influence of the distance from the reservoir on the expansion of anthropogenic activities. This methodology was used for the scenarios of pre-inauguration, completion of phase I, beginning of construction phase II, full completion of the Tucuruí hydroelectric project, and the current scenario of the region. The results showed that the highest deforestation rate occurred in the first period of the analysis, due to the areas submerged by the reservoir and due to the anthropogenic disturbances, such as timber extraction, road construction, and the conversion of forests into large areas of agribusiness.

Secondary forests (SF) have a large climate mitigation potential, given their ability to sequester carbon up to 20 times faster than old-growth forests. Environmental variability and anthropogenic disturbances lead to uncertainties in estimating spatial patterns of SF carbon sequestration rates. Here we quantify the influence of environmental and disturbance drivers on the rate and spatial patterns of regrowth in the Brazilian Amazon, by integrating a 33-year land cover timeseries with a 2017 Aboveground Biomass dataset. Carbon sequestration rates of young Amazonian SF (-1 yr-1) than in the east (1.3±0.3 MgC ha-1 yr-1). Disturbances reduce SF regrowth rates by 8–50% (0.6 – 1.3 MgC ha-1 yr-1). We estimate the 2017 SF carbon stock to be 294 TgC, which could be 8% higher by avoiding fires and repeated deforestation. Maintaining the 2017 SF area has the potential to accumulate ~15 TgC yr-1 until 2030, contributing ~5% to Brazil’s 2030 net emissions reduction target. Supporting SF and old-growth forests conservation alongside the expansion of SF in deforested areas is therefore a viable nature-based climate mitigation solution.

Synthetic aperture radar (SAR) data has been an alternative for monitoring ground targets, especially in areas with cloud cover. This study evaluates the potential of Sentinel-1A attributes for mapping land use and land cover (LULC) in a region of the Brazilian Amazon, using two different machine learning classifiers: Random Forest (RF) and Support Vector Machine (SVM). Different scenarios were used that combined backscattering, polarimetry, and interferometry to the classification process, which was divided into two phases to improve the results. The RF shows superiority over the SVM for almost all scenarios for the two phases of the mapping. The scenario with all data, presented the best results with both classifiers. The final maps with RF and SVM, obtained a global accuracy of 82.7% and 74.5%, respectively. This study demonstrated the potential of Sentinel-1 to map LULC classes in the Amazon region using a classification in two phases.

The expansion of the agricultural frontier is a reality in the Amazon region and in the State of Pará, agricultural activities have moved to the Southwest mesoregion of the state, implying in the increase of deforestation in the municipalities embargoed and priority sayings according to the Green Municipalities Program (PMV). Therefore, this research aimed to analyze the advance of the agricultural frontier in view of the PMV policy that prioritizes its actions to combat deforestation in the so-called embargoed municipalities, diametrically opposed to the group of green municipalities (MVs), which according to the PMV, has lower risk of deforestation in the State of Pará. It was verified that among the municipalities controlled (green municipalities)by the PMV deforestation remained stable and among the priority municipalities, deforestation increased substantially in the period from 2004 to 2016 even in the face of the impositions imposed by the program. Concomitantly, a large part of these municipalities are in the new frontier expansion areas, and the growth of agricultural and logging activities in terms of quantity and monetary values has stimulated this displacement. Energy projects and opening roads also contribute to this scenario. The inflection of environmental policies and the effective municipal environmental management that permeates the emerging concept of local governance are fundamental for the control of deforestation in Pará.Keywords: deforestation; frontier; priority municipalities.Article received on September 23, 2019.

Brazil contains two-thirds of remaining Amazonian rainforests and is responsible for the most Amazon forest loss. Primary forest loss in the Brazilian Amazon has declined considerably since 2004 but secondary forest loss has never been quantified. We use a recently developed high-resolution land use/land cover dataset to track secondary forests in the Brazilian Amazon over 14 yr, providing the first estimates of secondary forest loss for the region. We find that secondary forest loss increased by (187 ± 48)% from 2008 to 2014. Moreover, the proportion of total forest loss accounted for by secondary forests rose from (37 ± 3)% in 2000 to (72 ± 5)% in 2014. The recent acceleration in secondary forests loss occurred across the entire region and was not driven simply by increasing secondary forest area but probably a conscious preferential shift towards clearance of a little-protected forest ecosystem (secondary forests). Our results suggest that secondary forests loss has eased deforestation pressure on primary forests. However, this has been at the expense of a lost carbon sequestration opportunity of 2.59–2.66 Pg C over our study period.

A Faixa de Fronteira da Amazônia Legal é uma região complexa e com grande contraste social, ambiental e econômico. Cáceres (MT) e Oriximiná (PA) ilustram essa realidade: tem origens similares, ligadas à dinâmica dos rios, mas percorreram trajetórias inteiramente diferentes após a intervenção do governo federal na Amazônia, a partir de 1960. Atualmente, Cáceres possui economia com base no comércio, serviços, turismo e, principalmente, na agropecuária extensiva, que corresponde a 82,8% da área desmatada no município. Oriximiná tem na exploração de bauxita a sua base econômica, apresentando 94% de seu território ocupado por floresta nativa; em 2014, a pecuária ocupava 34% da área desmatada no município. O objetivo deste trabalho é analisar como o uso da terra influencia as dinâmicas territoriais desses municípios, e como estes se relacionam com suas fronteiras. Para a realização deste trabalho foram empregados dados de uso e cobertura da terra, referentes aos anos de 2004 e 2014, oriundos do mapeamento realizado pelo Projeto TerraClass (2016), além de informações provenientes de levantamento bibliográfico.

A bacia hidrográfica do rio Marapanim está localizada na região nordeste do estado do Pará, que se constitui em uma das fronteiras de colonização agrícola mais antiga da Amazônia, e que ao longo do seu processo de ocupação sofreu forte pressão sobre sua cobertura vegetal. O objetivo deste trabalho é analisar a dinâmica do desmatamento, a partir dos usos da terra, e a aplicabilidade das Áreas Prioritárias para Conservação (APC) nas políticas de gestão territorial do estado como o Zoneamento Ecológico Econômico (ZEE). Os resultados mostraram um quadro grave de supressão da cobertura vegetal, que resultou em 80% da área da bacia desmatada. Esse quadro é acompanhado pela fragmentação da floresta o que ocasiona fragmentação de habitats e perda de biodiversidade. Como alternativa para a reversão desse quadro, propõe-se ações associadas ao ordenamento dos planos diretores municipais, à gestão integrada, à formação de cadeia produtiva para uso sustentável dos recursos naturais, à criação de UCs, uma vez que na área da bacia existem apenas duas de uso sustentável que são as Reservas Extrativistas Marinhas Cuiara Cuinarana e Mestre Lucindo, a fim de garantir a conservação e proteção dos remanescentes florestais na região da bacia hidrográfica do rio Marapanim. A B S T R A C TThe Marapanim River Basin, located in the northeastern region of Pará, is one of the oldest agricultural colonization frontiers in the Amazon, which caused strong pressure on the original vegetation during the occupation process. The objective of this work is to analyze the dynamics of deforestation due to land use and the importance of the Priority Areas for Conservation (PAC) for the state's territorial management policies such as the Economic Ecological Zoning (EEZ). The results showed that 80% of the basin area is already deforested. The consequences are forest fragmentation, which leads to fragmentation of habitats and loss of biodiversity. To mitigate the problem, the authors propose associated actions to (i) the municipal management plans, (ii) the integrated management, (iii) the creation of productivity chains for the sustainable use of natural resources, and (iv) the implementation of new conservation units, since there are actually only two units for sustainable use that are Marine Extractive Reserves Cuiara Cuinarana and Mestre Lucindo in the basin area. Such a methodology will ensure conservation and protection of the remaining forests in the Marapanim river basinKey words: Land use. Biodiversity. River basin.

Since the 1980s, mangrove cover mapping has become a common scientific task. However, the systematic and continuous identification of vegetation cover, whether on a global or regional scale, demands large storage and processing capacities. 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. The first period, from 1985 to 1998, shows an upward trend, which seems to be related more to the uneven distribution of Landsat data than to a regeneration of Brazilian mangroves. In the second period, from 1999 to 2018, a trend of mangrove area loss was registered, reaching up to 2% of the mangrove forest. On a regional scale, ~85% of Brazil’s mangrove cover is in the states of Maranhão, Pará, Amapá and Bahia. In terms of persistence, ~75% of the Brazilian mangroves remained unchanged for two decades or more.

Tropical secondary vegetation is of particular interest as carbon sinks, potential lands for agriculture and livestock expansion, biodiversity conservation and ecosystem services. Until mid-2000s estimates of secondary vegetation in the Brazilian Amazon indicated a progressive increase of this cover, however after 2010, only 1197 km2 of additional secondary vegetation were generated, while 42,040 km2 were converted into other land-covers. Meanwhile, deforestation rates progressively decreased to be around 6000 km2 in contrast to the peak of 27,772 km2 in 2004, what suggests that changes in land-cover dynamics with respect to deforestation may be related to a reduction in secondary vegetation. Hence, in this paper, we work with the hypothesis that, in a context of decreasing deforestation rates, the historic pattern of progressive accumulation of secondary vegetation in the Brazilian Amazon changed as a consequence of the re-conversion of this cover, as well as other land-covers relevant in the process of regeneration, into different land-covers that expanded in this period. Our focus was then to investigate, on a regional scale, the spatiotemporal patterns of secondary vegetation with respect to different land-covers in Pará based on (i) a quantitative analysis of transitions between land-covers, and (ii) on clustering patterns of secondary vegetation cover and their relations with clustering patterns of pastures, small-scale and industrial agriculture. We found that more secondary vegetation was converted into land-covers that expanded in the period i.e. clean pasture, mechanized agriculture, and palm oil, with secondary vegetation and land-covers important for regeneration (i.e. small-scale agriculture and regeneration with pasture) experiencing an overall reduction and contributing less to the concentration of secondary vegetation after 2010. Clusters of high values (hotspots) of secondary vegetation prevailed in the north, while clusters of low values (cold spots) prevailed in the south of Pará, a pattern that is explained by different histories of occupation and deforestation dynamics, as well as distinct regional land dynamics in the past decade. As a first contribution to understanding the dynamics of secondary vegetation in a context of decreasing deforestation rates, our results show that the increased pressure to halt deforestation had effects over the dynamics of this land-cover, as well as over land-covers relevant to regeneration.

The objective of this work was to analyze land use dynamics in the Brazilian Cerrado region from 2002 to 2013. This analysis was based on the interpretation of Landsat satellite images carried out by the projects Projeto de Conservação e Utilização Sustentável da Diversidade Biológica Brasileira (Probio) and TerraClass Cerrado 2013, both coordinated by Ministério do Meio Ambiente. In 2002, 38.9% of the Cerrado was covered by some type of anthropic activity. In 2013, this percentage increased to 43.4%. One of the main highlights is the emergence of a new agricultural frontier in the northern region of the study area, known as Matopiba.
