The Brazilian Amazon Satellite Monitoring Program (PRODES Amazonia) tracks forest loss in the but excludes about 6.6% ( ~ 280,000 km²) of non-forest vegetation (NF). Here we developed PRODES NF system to address this gap by adapting well-established methodology Amazonia. Initial findings from show that lost 10.46% 30,000 area, mainly last two decades, with estates Mato Grosso, Roraima, and Amapá being primary hotspots losses. Savannas were most affected (13.3% their extent). strongly...
Abstract. This study investigated the pattern distribution of fires in Brazilian Amazon and their relationship with deforested areas from 2003 to 2022. The primary objective was analyze fire spots’ spatial temporal variation. First, we examine whether open vegetation (non-forest areas) exhibit a higher density spots than forested areas. Second, how varies time elapsed since deforestation. Using recent monitoring data satellite imagery, employed statistical techniques reveal significant...
This report documents observations and analyses from fieldwork conducted between March 20 28, 2023, in the state of Roraima, as a collaboration National Institute for Space Research (INPE) Brazilian Agricultural Agency Roraima (Embrapa Roraima). The study investigated selected features both forested non-forested areas, confirming their anthropization status according to PRODES DETER monitoring programs (INPE). Additionally, it aimed identify land uses covers these areas. covered 2,288 km...
In this study, we present the initial results of pilot project applying Near Real-Time Deforestation Detection System (DETER), initially designed for monitoring forest ecosystems (DETER Amazon), recently expanded to surveil an area approximately 280,000 km² non-forest natural vegetation (NF) in Brazilian Amazon. The system issues two types alerts: 1) NF suppression alerts, categorized into three classes (suppression with exposed soil, cultivated area, and by mining) 2) burn scars, based on...
<title>Abstract</title> Deforestation in the Brazilian Amazon has been monitored since 1988 by Satellite Monitoring Program (PRODES Amazonia), and its data pivotal guiding environmental public policies country. While forest formations are officially supported a monitoring program, significant portion of biome (6.6 % or ~280,000 km²) constituted non-forest (NF) phytophysiognomies (e.g., savanna, grasslands, flood lands) still unmonitored. To address this information gap, PRODES NF system was...
Transfer learning reuses a pre-trained model on new related problem, which can be useful for monitoring large areas such as the Amazon biome. A given object must have similar spectral characteristics in data used this type of analysis, achieved using relative calibration techniques. In article, we present process multitemporal images and evaluate its impacts subpixel classification process. MODIS from region, collected between 2013 2017, were relatively calibrated 2012 image reference...
O presente artigo traz alguns resultados sobre o universo do professor de Arte das escolas públicas municípios Extremo Oeste Catarinense. Esses dados foram coletados no segundo semestre 2017 nos Barra Bonita, Bandeirante, Belmonte, Descanso, Guaraciaba, Paraíso e São Miguel Oeste. principal objetivo foi identificar as realidades profissionais dos professores ensino fundamental, localizando-os na região, através instituições redes sociais. A partir desse trabalho concluímos que, quando...
