Audiência pública - Código Florestal (21/23) New Satellite System Analyzes Brazil’s Forests Weekly. Will It Help Curb Deforestation? A version of this post also appears on the Global Forest Watch blog.
As Rio’s Olympic stadiums empty and athletes head home, Brazil’s big moment in the global spotlight seems to be drawing to a close. But if we take the opening ceremony’s commentary on forest restoration and climate change to heart, Brazil is more relevant than ever. Brazil’s forests, from the steamy depths of the Amazon to the tropical savannahs of the Cerrado, represent one of the world’s best chances for reducing greenhouse gas emissions and fighting climate change. And for the first time, Brazil and the rest of the world have a tool to track how these forests are changing every week. Leads 1st Local-to-Global Mapping of Forest. COLLEGE PARK, Md. - A University of Maryland-led, multi-organizational team has created the first high-resolution global map of forest extent, loss and gain.
This free resource greatly improves the ability to understand human and naturally-induced forest changes and the local to global implications of these changes on environmental, economic and other natural and societal systems, members of the team say. In a new study, the team of 15 university, Google and government researchers reports a global loss of 2.3 million square kilometers (888,000 square miles) of forest between 2000 and 2012 and a gain of 800,000 square kilometers (309,000 square miles) of new forest. Their study, published online on November 14 in the journal Science, documents the new database, including a number of key findings on global forest change. For example, the tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2,101 square kilometers (811 square miles) per year. Global Forest Change. Results from time-series analysis of Landsat images in characterizing global forest extent and change from 2000 through 2014.

Conditions created by the strong El Niño event that warmed up Pacific waters in 2015 and early 2016 altered rainfall patterns around the world.
In the Amazon basin, that meant reduced rainfall during the wet season, plunging some parts of the region into severe drought. According to NASA, the Amazon is the driest it’s been at the start of the dry season since 2002 — and that probably means the rainforest is in for a particularly nasty wildfire season, according to Doug Morton, an Earth scientist with the U.S. agency and a co-creator of the Amazon fire forecast, which uses climate observations and active fire detections by NASA satellites to predict fire season severity. “Severe drought conditions at the start of the dry season have set the stage for extreme fire risk in 2016 across the southern Amazon,” Morton said in a statement. Predicting South American fire season severity (FSS) Predicting South American fire season severity (FSS) This webpage presents a prediction of fire risk for the 2015 dry season in high biomass burning regions of South America.
The following figure presents fire season severity indices (FSSI, ranging from 0-100) for 6 states in Brazil (Acre, Amazonas, Maranhão, Mato Grosso, Pará, and Rondônia), 3 departments in Bolivia (El Beni, Pando, and Santa Cruz), and one country (Peru) using sea surface temperature information through the end of May. Green indicates below average predictions of fire activity whereas orange and red indicate above average activity. Predicting South American fire season severity (FSS) Essa pagina apresenta a previsão para o período severo de queimadas durante a época seca de 2012.
A figura abaixo mostra a previsão para 2012 e está atualizada até março 2012 em termos do Índice Sazonal da Severidade de Fogo (Fire Season Severity Index, FSSI, com intervalo entre 0-100).
