چکیده
Abstract Brazil is currently the largest contributor of land use and cover change (LULCC) carbon dioxide net emissions worldwide, representing 17%–29% global total. There is, however, a lack agreement among different methodologies on magnitude trends in LULCC their geographic distribution. Here we perform an evaluation datasets for Brazil, including those used annual budget (GCB), national Brazilian assessments over period 2000–2018. Results show that latest HYDE 3.3 dataset, based new FAO inventory estimates multi-annual ESA CCI satellite-based maps, can represent observed spatial variation last decades, improvement 3.2 data previously GCB. However, assessed with lower than MapBiomas. We MapBiomas as input to bookkeeping model (bookkeeping emission, BLUE) process-based Dynamic Global Vegetation Model (JULES-ES) determine Brazil’s 2000–2019. mean 0.1–0.4 PgC yr ?1 , compared 0.1–0.24 reported by Greenhouse Gas Emissions Estimation System changes forest sector (SEEG/LULUCF) its assessment deforestation Brazil. Both JULES-ES BLUE now simulate slowdown after 2004 (?0.006 ?0.004 ?2 3.3, ?0.014 ?0.016 MapBiomas, respectively), INPE-EM, Houghton Nassikas book-keeping models, 4th greenhouse gas inventories. The inclusion Earth observation has improved representation thus capability emissions. This will likely contribute reduce uncertainty emissions, better constrains GCB assessments.

From Land Cover to Land Use: A Methodology to Assess Land Use from Remote Sensing Data
The “land use” concept has evolved during recent decades and it is now considered as the socioeconomic function of land. Land use representation and land use change assessment through remote sensing still remains one of the major challenges for the remote sensing scientific community. In this paper we present a methodological approach based on remote sensing techniques to assess land use in acc...
متن کاملTropical land use land cover mapping in Pará (Brazil) using discriminative Markov random fields and multi-temporal TerraSAR-X data
Remote sensing satellite data offer the unique possibility to map land use land cover transformations by providing spatially explicit information. However, detection of short-term processes and land use patterns of high spatial-temporal variability is a challenging task. We present a novel framework using multi-temporal TerraSAR-X data and machine learning techniques, namely Discriminative Mark...
