亚马逊雨林森林采伐一年间增长28%
Brazil says the rate of deforestation in the Amazon increased by 28% between August 2012 and last July.
巴西政府称，从2012年8月至2013年7月，亚马逊雨林的森林采伐增长28%。
The government is working to reverse this "crime", Environment Minister Izabella Teixeira said.
Activists have blamed the increase in destruction on a controversial reform to Brazil's forest protection law.
Last year Brazil reported the lowest rate of deforestation in the Amazon since monitoring began.
The provisional statistics from August 2012 to last July suggest that the area suffering deforestation was 5,843 sq km (2,255 sq miles), compared to 4,571 sq km (1,765 sq miles) in the previous 12 months.
The 28% rise interrupts a period of declining deforestation which began in 2009. However, it still remains the second lowest annual figure for forest loss in absolute terms.
The worst year on record was 2004, when 27,000 sq km of forest was destroyed.
Monthly data from several scientific institutions had suggested the deforestation rate might be on the rise.
