Although deforestation rates in the Brazilian Amazon are well known, extent of area affected by forest degradation is a notable data gap, with implications for conservation biology, carbon cycle science, and international policy. We generated long-term spatially quantified assessment entire from 1992 to 2014. measured mapped full range activities that degrade forests evaluated relationship deforestation. From 2014, total degraded was 337,427 square kilometers (km2), compared 308,311 km2 were...
In this study, we assessed the impacts of land use and climate changes on river flows 81 watersheds within Cerrado biome, Brazil, based a comprehensive analysis field secondary data acquired between 1985 2018. Complementarily, projected future deforestation scenario up to 2050 predicted their surface water in study area. We observed that direct by large-scale oriented production irrigated agricultural commodities have more significantly impacted than changes. estimated an average decrease...
The socioeconomic and ecological aspects of landuse change are interrelated, especially in the Brazilian Amazon, where immigrants rapidly cutting forest to establish farms. A computer simulation has been developed that projects land‐use changes, carbon release, time a family can remain on farm lot as function initial soil vegetation conditions, market road infrastructure, decision variables. model simulates extremes practices typical conditions for central Rondônia, Brazil. Typical Rondônia...
The rapid environmental changes occurring in the Brazilian Amazon due to widespread deforestation have attracted attention of scientific community for several decades. A topic particular interest involves assessment combined impacts selective logging and forest fires. Forest disturbances by fires may vary scale, from local global changes, mostly related increase carbon dioxide released into atmosphere. Selective activities been reported studies as important agents land-use land-cover...
Over the past several decades, Brazilian State of Rondônia has been destination many rural migrants drawn from Brazil's middle southern regions by massive government colonization projects. Factors such as explosive population growth, logging, mining, small-scale farming and ranching have synergistically fuelled deforestation in state. The total area deforested 1978 was 4200 km 2 . In 1988, increased to 30 000 , 1998 53 300 year 2003, a 67 764 deforested. response high rate observed other...
Large‐scale selective logging is a relatively new activity in the Amazon and its full consequences have yet to be evaluated. Impacts by alone been estimated increase approximately 4–7% of annual carbon release from deforestation. In this research, visual interpretation semi‐automated remote sensing techniques were applied identify map areas tropical terra firme (upland) forests together with correlated multi‐annual measurement results for 1992, 1996, 1999, Brazilian Amazon. The research...
ABSTRACT Although soybean production has been increasing in the state of Rondônia last decade, planted area estimated indirectly using secondary datasets, which limited understanding its spatiotemporal distribution patterns. This study aimed to map and analyze spatial patterns expansion Rondônia. We developed a classification technique based on Spectral Mixture Analysis (SMA) derived from Landsat imagery Decision Tree Classification detect plantations 2000, 2005, 2010, 2014. The showed 93%...
Para maximizar o comércio de commodities, governo brasileiro lançou Programa Aceleração do Crescimento (PAC) para modernizar a infraestrutura país. Além disso, ambos os governos federal e estadual têm aumentado financiamento público megaempreendimentos privados através parcerias público/privadas. A combinação dessas iniciativas resultou na invasão grandes corporações (nacionais multinacionais) em territórios ocupados por índios, quilombolas camponeses. Apesar fato que Constituição Federal...
No presente estudo, foi avaliada a acurácia dos mapeamentos do desmatamento conduzidos pelo Programa de Monitoramento Desflorestamento na Amazônia (PRODES) Instituto Nacional Pesquisas Espaciais (INPE) e pela Secretaria Estado Desenvolvimento Ambiental (SEDAM), para o Rondônia, no período entre 2001 2011, utilizando imagens Landsat 5 TM. Com base nos resultados deste os SEDAM PRODES-INPE apresentaram coeficientes Kappa similares, estimados em 0,89 0,87, respectivamente. Os dados sistemas...
Does the adoption of agroforestry by small farmers in Brazilian Amazon promote secondary forest succession on degraded pastures and crop fields? New results from a small-scale farm demonstration project, Rondônia Agroforestry Pilot Project (RAPP) that began 1992 are presented this paper. In 1992, 242 were surveyed stratified random sampling protocol, 50 whom selected to participate RAPP, constituting its experimental group. The remaining 191 served as control Farmers both groups re-surveyed...
