Brazil has a monitoring system to track annual forest conversion in the Amazon and most recently monitor Cerrado biome. However, there is still gap of land use cover (LULC) information all Brazilian biomes country. Existing countrywide efforts map lack regularly updates high spatial resolution time-series data better understand historical dynamics, subsequent impacts country biomes. In this study, we described novel approach results achieved by multi-disciplinary network called MapBiomas...
Forest degradation in the Brazilian Amazon due to selective logging and forest fires may greatly increase human footprint beyond outright deforestation. We demonstrate a method quantify annual deforestation simultaneously across entire region for years 2000–2010 using high-resolution Landsat satellite imagery. Combining spectral mixture analysis, normalized difference fraction index, knowledge-based decision tree classification, we mapped assessed accuracy (0.97), (0.85) (0.82) with an...
Abstract This work presents the SEEG platform, a 46-year long dataset of greenhouse gas emissions (GHG) in Brazil (1970–2015) providing more than 2 million data records for Agriculture, Energy, Industry, Waste and Land Use Change Sectors at national subnational levels. The was developed by Climate Observatory, Brazilian civil society initiative, based on IPCC guidelines National Inventories embedded with country specific emission factors processes, raw from multiple official non-official...
The Brazilian Amazon is one of the areas on planet with fastest changes in forest cover due to deforestation associated agricultural expansion and infrastructure development. These drivers change, directly indirectly, affect water ecosystem. In this study, we present a long-term spatiotemporal analysis surface annual change address potential connections deforestation, climate region. To do that, used Landsat Data Archive (LDA), Earth Engine cloud computing platform, map analyze between 1985...
In this article, we simulate forest fragmentation patterns by reference to the actual decision-making of agents engaged in process itself. We take as our empirical case Brazilian Amazon basin associated with road-building loggers. Roads built private sector, particularly loggers, play a decisive role dynamics frontier expansion Amazon. Our objective is explain manner which logging roads manifest spatially, thereby creating fragmented landscapes small portion so-called “Terra do Meio,” region...
Forest-fragmentation-related edge effects are one of the major causes forest degradation in Amazonia and their spatio-temporal dynamics highly influenced by annual deforestation patterns. Rapid biomass collapse due to fragments has been reported Brazilian Amazon; however collective impacts this process on Amazonian carbon fluxes poorly understood. We estimated loss emissions from fragmentation related basis INPE (Brazilian National Space Research Institute) PRODES data volume data. The areas...
The Moderate Resolution Imaging Spectroradiometer (MODIS) has been used in several remote sensing studies, including land, ocean, and atmospheric applications. advantages of this sensor are its high spectral resolution, with 36 bands; revisiting frequency; public domain availability. first seven bands MODIS the visible, near-infrared, mid-infrared regions electromagnetic spectrum which sensitive to changes due deforestation, burned areas, vegetation regrowth, among other land-use changes,...
Estimates of the area land cover classes or change are frequently calculated from classification maps by counting pixels labeled as each class in map. This procedure is known to produce biased estimates for many widely used algorithms, including random forests. Poststratification estimation using mapped strata has been proposed obtain unbiased areas. Still, method requires additional sampling units, which may not be available most efficient depending on application. Alternatively, consistent...
Forest fragmentation due to deforestation is one of the major causes forest degradation in Amazon. Biomass collapse near edges, especially within 100 m, alters aboveground biomass and has potentially important implications for carbon emissions region. This phenomenon tightly linked spatial temporal dynamics edges a landscape. However, potential loss from these spatiotemporal changes have never been estimated actual landscapes We conducted deep analysis Rondônia, southwestern Brazilian...
This article addresses the spatial decision-making of loggers and implications for forest fragmentation in Amazon basin. It provides a behavioral explanation by modeling how build road networks, typically abandoned upon removal hardwoods. Logging networks provide access to land, settlers who take advantage them clear fields pastures that accentuate their signatures. In shaping agricultural activities, these organize emergent patterns fragmentation, even though move elsewhere. The goal is...
Historic carbon emissions are an important foundation for proposed efforts to Reduce Emissions from Deforestation and forest Degradation enhance stocks through conservation sustainable management (REDD+). The level of uncertainty in historic estimates is also critical REDD+, since high uncertainties could limit climate benefits credited mitigation actions. Here, we analyzed source data based on the range available deforestation, degradation, stock Brazilian state Mato Grosso during...
Abstract As Amazon deforestation rates reach the highest levels observed in past decade, it is extremely important to direct conservation efforts regions containing preserved forests with a high risk of deforestation. This requires forecasting deforestation, complex endeavor due interplay multiple socioeconomic, political, and environmental factors across different spatial temporal scales. Here we couple high-resolution land-cover maps Bayesian hierarchical models identify main drivers...
We performed high‐spatial and high‐temporal resolution modeling of carbon stocks fluxes in the state Rondônia, Brazil for period 1985–2009, using annual Landsat‐derived land cover classifications a modified bookkeeping approach. According to these results, Rondônia contributed 3.5–4% pantropical humid forest deforestation emissions over this period. Similar well‐known figures reported by Brazilian Space Agency, we found decline rates since 2006. However, estimate lesser decrease, with...
A demanda por informação geográfica detalhada para gestão socioambiental de municípios da Amazônia aumentou recentemente com a criação uma lista críticos que mais desmatam as florestas região, instituída pelo Ministério do Meio Ambiente. Duas informações são essenciais saída crítica: o georeferenciamento propriedades rurais e sua inserção no Cadastro Ambiental Rural (CAR); monitoramento desmatamento. Neste artigo, apresentamos os resultados construção base geográficas Paragominas crítica...
In Brazil, a significant reduction in deforestation rates occurred during the last decade. spite of that fact, average annual are still too high, approximately 400.000 ha/year (INPE/Prodes). The projects emissions through avoided (REED+) an important tool to reduce Brazil. Understanding amazon forest structure, terms biomass stock is key design strategies. this work, we analyze data results from aboveground 1,019.346,27 hectares state Pará. It was collected 16,722 trees 83 random independent...
