Controlling deforestation in Brazil's Amazon region has long been illusive despite repeated efforts of government authorities to slow the process. From 1997 to 2000, deforestation rates in Brazil's 9-state "Legal Amazon" region continually crept upward. Now, a licensing and enforcement program for ...
The rapid deforestation in the Amazon rainforest has raised global concerns about climate change and biodiversity loss. (亚马逊雨林的快速森林砍伐引起了全球对气候变化和生物多样性丧失的关注。) Deforestation contributes significantly to the increase in greenhouse gases, which accelerates...
The figures were compiled in an annual report issued by Prodes, a project for remote sensing deforestation rates in the Amazon. It is considered the most accurate mechanism for measuring forest loss. Over the past two decades, the deforestation rate in the Brazilian Amazon peaked in 2004, when...

In June 2019 alone, deforestation rates in the Brazilian Amazon increased 88% compared to the same month last year. There are also troubling new hotspots of increasing forest loss in West Africa and the Congo Basin—the Democratic Republic of Congo has more than doubled its deforest...
14.2 Rates and extent of deforestation Deforestation probably originated with the use of fire, and estimates are that 40%–50% of the Earth's original forest area has been lost. Some of the losses happened before settled agriculture began, approximately 10,000 years ago, but only in recent de...

Amazon deforestation. Our model differs from previous models in three ways: (1) it is probabilistic and quantifies uncertainty around predictions and parameters; (2) the overall deforestation rate emerges “bottom up”, as the sum of local-scale deforestation driven by local...
The Amazon is by far the most famous part of Brazil outside Brazil, but the real engine of agricultural growth in Brazil has been, actually, more the Cerrado, which is a mix of savannah and woodland-type biome. It’s rather similar to the U.S., actually. The history of ...
