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...
Brazil's controversial new Forest Code grants amnesty to illegal deforesters, but creates mechanisms for forest conservation.
Abstract: Conservation scientists generally agree that many types of protected areas will be needed to protect tropical forests. But little is known the comparative performance inhabited and uninhabited reserves in slowing most extreme form forest disturbance: conversion agriculture. We used satellite‐based maps land cover fire occurrence Brazilian Amazon compare large (>10,000 ha) (parks) (indigenous lands, extractive reserves, national forests) reserves. Reserves significantly reduced...
The incidence and importance of fire in the Amazon have increased substantially during past decade, but effects this disturbance force are still poorly understood. forest dynamics two regions eastern were studied. Accidental fires affected nearly 50 percent remaining forests caused more deforestation than has intentional clearing recent years. Forest create positive feedbacks future susceptibility, fuel loading, intensity. Unless current land use practices changed, potential to transform...
Significance Climate change alone is unlikely to drive severe tropical forest degradation in the next few decades, but an alternative process associated with weather and fires already operating southeastern Amazonia. Recent droughts caused greatly elevated fire-induced tree mortality a fire experiment widespread regional that burned 5–12% of Amazon forests. These results suggest feedbacks between extreme climatic conditions could increase likelihood “dieback” near-term. To secure integrity...
Government commitments and market transitions lay the foundation for an effort to save forest reduce carbon emission.
Abstract Understory fires, which burn the floor of standing forests, are one most important types forest impoverishment in Amazon, especially during severe droughts El Niño–Southern Oscillation (ENSO) episodes. However, authors aware no estimates areal extent these fires for Brazilian Amazon and, hence, their contribution to carbon fluxes atmosphere. In this paper, area understory region is calculated an Niño (1998) and a non–El (1995) year based on fire scars mapped with satellite images...
Changes in weather and land use are transforming the spatial temporal characteristics of fire regimes Amazonia, with important effects on functioning dense (i.e., closed-canopy), open-canopy, transitional forests across Basin. To quantify, document, describe recent changes forest regimes, we sampled 6 million ha these three representative eastern southern edges Amazon using 24 years (1983–2007) satellite-derived annual scar maps 16 monthly hot pixel information (1992–2007). Our results...
Brazil has become an agricultural powerhouse, producing roughly 30 % of the world's soy and 15 its beef by 2013 – yet historically much that growth come at expense native ecosystems. Since 1985, pastures croplands have replaced nearly 65 Mha forests savannas in legal Amazon. A growing body work suggests this paradigm horizontal expansion agriculture over ecosystems is outdated brings negative social environmental outcomes. Here we propose four strategies can reduce deforestation, while...
Widespread in the subtropics and tropics of Southern Hemisphere, savannas are highly heterogeneous seasonal natural vegetation types, which makes change detection (natural vs. anthropogenic) a challenging task. The Brazilian Cerrado represents largest savanna South America, most threatened biome Brazil owing to agricultural expansion. To assess native (NV) areas susceptible anthropogenic over time, we classified 33 years (1985–2017) Landsat imagery available Google Earth Engine (GEE)...
Significance Brazil’s new Forest Code has the potential to halt illegal deforestation in country’s native forests and savannas through implementation of a federal land registry—along with powerful tools that facilitate enforcement give landowners pathway restoring or compensating their “forest deficits.” This study suggests these fall short promise. Although eastern Amazonia have been motivated join state registries, many continue deforest few restored illegally cleared areas. Results...
Fire is a significant agent of landscape transformation on Earth, and dynamic ephemeral process that challenging to map. Difficulties include the seasonality native vegetation in areas affected by fire, high levels spectral heterogeneity due spatial temporal variability burned areas, distinct persistence fire signal, increase cloud smoke cover surrounding difficulty detecting understory signals. To produce large-scale time-series area, robust number observations more efficient sampling...
Abstract The spatial distribution of human activities in forest frontier regions is strongly influenced by transportation infrastructure. With the planned paving 6000 km highway Amazon Basin, agricultural expansion will follow, triggering potentially large changes location and rate deforestation. We developed a land‐cover change simulation model that responsive to road policy intervention scenarios for BR‐163 central Amazonia. This corridor links cities Cuiabá, Brazil, Santarém, on southern...
Throughout human history, the world9s great forest formations have yielded to logging, cattle ranching, and agricultural expansion after transportation corridors made them accessible frontier settlers. The Brazilian Amazon could prove be an exception this historical trend, however. Recent advances in Brazil9s environmental management potentially preserve most Amazonian forests while fostering economic development, as demonstrated by CuiabA©a -SantarA©m highway, soon paved.
Halving carbon emissions from tropical deforestation by 2020 could help bring the international community closer to agreed goal of <2 degree increase in global average temperature change and is consistent with a target set last year governments, corporations, indigenous peoples' organizations non-governmental that signed New York Declaration on Forests (NYDF). We assemble refine robust dataset establish 2001-2013 benchmark for annual gross at 2.270 Gt CO2 yr(-1). Brazil did not sign NYDF,...
Widespread occurrence of fires in Amazonian forests is known to be associated with extreme droughts, but historical data on the location and extent forest are fundamental determining degree which climate conditions droughts have affected fire region. We used remote sensing derive a 23-year time series annual landscape-level burn scars fragmented eastern Amazon. Our scar set based new routine developed for Carnegie Landsat Analysis System (CLAS), called CLAS-BURN, calculate physically index...
