The Brazilian government has revised upward its estimate for the extent of Amazon rainforest destroyed last year. Figures released last week by Brazil’s National Space Research Agency (INPE) put Amazon deforestation at 6,207 square kilometres for the year ended July 31, 2015. That represents an increase of 6.5 percent relative to the estimate of 5,831 square kilometres published last December.

Greenpeace have released a publication outlining the economic exploitation issues of the Amazon rainforest and is demanding that the Brazilian government cancel hydropower projects such as the São Luiz do Tapajós (SLT) dam. This dam alone is expected to cause 2,200km2 of deforestation and to drown 400km2 of rainforest. Previous projects have led to huge habitats being wiped out causing significant impacts on the populations of fish, aquatic reptiles and the life cycles of local mammals.

While deforestation in the Brazilian Amazon has fallen sharply over the past decade, a larger share of forest loss is now being driven by smallholders who are more difficult to control, posing new challenges for the Brazilian government.

Satellite data analysis suggests deforestation in the Brazilian Amazon may have reached a 7-year high. Imazon, a Belém-based non-profit, released data showing deforestation in the region pacing ahead of the previous year’s level for 13 months consecutively. The 12-month moving average of short-term deforestation alert data has reached levels that have not been seen since 2008. This hasn’t yet been confirmed by the Brazilian government who now report statistics quarterly for its deforestation system, but recent figures released by INPE mirror this data.

Researchers have said that deforestation of the Amazon in March has almost tripled compared to March 2014. Imazon, a Brazilian non-profit research institution, say that 22 square miles of forest have been removed across the Amazon region in March, compared to 7.7 square miles in March 2014. Three quarters of the cleared forest was focused in Mato Grosso, where part of the Pantanal wetlands are found. These figures by Imazon differ to those of the Brazilian government who suggested that deforestation had actually fallen by 18% across the nine states forming the Amazon basin.

The Brazilian government has said forest clearance in the Amazon has decreased by 18% over the past year to July 2014, but environmental NGOs disagree saying their data shows increased rates of forest loss. Brazil’s environment minister, Izabella Teixeira, said approximately 4800km2 was lost between August 2013 and July 2014. This was down from 5900km2 during the same period a year earlier. But WWF and Imazon disagree and say that alternative satellite monitoring systems, different to those used by the government, show a staggering increase in forest loss of over 460%. Ms Teixeira maintained that the official government estimate was the most accurate: “Anything else is speculation. We have been working hard to end deforestation.”

Brazil’s Environmental Minister Izabella Teixeira has said that the rate of deforestation in the Amazon rainforest has increased by 28 per cent in the past year.
Provisional statistics suggest that the increase has seen 5,843 sq km of rainforest suffer from deforestation between August 2012 and July 2013, compared to 4,571 sq km in the previous 12 months. Although the statistics are still significantly below those of 2004, the Brazilian Government is still concerned that the rate of deforestation is now on the rise. Many environmentalists blame the upwards trend on a forest protection law reform in 2012, which reduced the protected areas in farms and declared an amnesty for all areas destroyed before 2008.

The Brazilian government released data that confirmed an increase in Amazon forest loss, with the majority of clearing taking place in Mato Grosso for agriculture. Reasons for the increase are thought to derive from weakening of the country's Forest Code, which limits clearing on private forest land, and agricultural exports have also become more commercially attractive for farmers.

Pressure is building on President Dilma Rousseff to veto The Forest Code ahead of the deadline on 25th May. The Forest Code reduces the obligation on landowners to protect Amazonian forest cover down from 80 to 50 per cent, leading to the potential loss of 190 million acres of forest according to the Brazilian Government’s Institute for Applied Economic Research. It is being seen as a battle between the increasingly powerful ‘ruralistas’, legislators representing agricultural interests, and a range of other stakeholders including environmental NGOs, leading national scientific groups, Brazilian celebrities and even many large businesses such as Tetra Pak Brasil.
