Scientists at UCL have defined three phases of global forest loss, the third of which we are living through now. They believe this third phase poses dangerous consequences if not correctly managed at a global scale. They believe the first phase happened over 6000 years ago when hunter-gatherers moved into tropical forests. The second phase saw the emergence of tropical agriculture. Despite altering the forest both of these phases maintained its overall health. The third phase – known as ‘Global Integration’ - has much greater impacts and is defined by distant decision-makers directing forest and agricultural land use. There have been positive moves, such as the UN’s New York Declaration of Forests agreeing to halt deforestation and restore 150 million hectares. But moves to expand the palm oil industry in to Africa are concerning and the study worries about the implications for the continent’s natural forests. The report calls for a renewed attention on forests at the Paris climate talks, where commitments to reduce deforestation and secure alternative finance are essential to success.

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.

Imazon’s newest study shows that, between August 2012 and July 2014, 90% deforestation in Brazilian Amazon happened in protected areas, while 10% occurred outside protected areas. During the two years’ period, forest loss was heavily concentrated in areas where infrastructure was expanding and management plans and funding were lacking. The study also recommends possible measures to against the deforestation, including law enforcement, eviction of non-traditional settlers from illegally occupied forests, and state resettlement schemes, etc.

While estimates from various UN bodies claim “decreasing deforestation rates and increased afforestation” over recent years, a new study in the journal Geophysical Research Letters indicates a 62% acceleration in net deforestation in the humid tropics from the 1990s to the 2000s. The new study used satellite images to examine the tropical forests of 34 countries, including Brazil, Indonesia and Thailand, that collectively house 80 percent of the world’s tropical forest area. Brazil “dominated” tropical forest losses, according to the study, showing a 33 percent acceleration in the amount of forest that was lost over the time period. According to the researchers the difference is because the UN mostly uses country based self-reporting rather than analysis of satellite data. The drought currently hitting Brazil has in part been blamed on deforestation.

A study published in the journal Science, led by Holly Gibbs of the University of Wisconsin-Madison, found that the moratorium on forest conversion established by Brazilian soy giants in 2006 dramatically reduce deforestation for soy expansion in the Amazon, and have been more effective in cutting forest destruction than the government's land use policy in the region. The study is based on spatial analysis across thousands of farm in the Brazilian Amazon and cerrado, a woody grassland, and researchers compared forest loss before and after the moratorium was established.

According to a report released by Forest Watch Indonesia roughly half of Indonesia’s natural forest loss occurs outside officially designated concession areas. Indonesia’s forest cover is now down to 46% of its land mass, with natural forest totalling 82.5 million hectares. The report blames bureaucracy associated with managing Indonesia’s forests, and Forest Watch Indonesia has put forest governance at the centre of efforts to fix Indonesia’s forestry sector.

The Peruvian environment ministry has confirmed that deforestation rates in the country have increased significantly in 2013. The actual forest cleared in 2013 was almost 30% higher than the average since 2001 – spiking at 145,000 hectares, compared to an average of 113,000 hectares. A majority of the loss has been attributed to agriculture. The 2013 spike hasn’t happened in isolation and data from recent years – including aggregated forest loss alerts from Global Forest Watch - has shown an upward trend of deforestation in the Peruvian Amazon.

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.”

A recent study in Nature Climate Change suggests that the rate of Deforestation in Indonesia is twice what is reported by the Government and that the Government’s 2011 regulations to combat deforestation have been largely ineffective. The report cites a Science report on the disparity between deforestation rates reported by the Indonesian government and the rate of deforestation calculated from satellite data. Green groups lobbying against palm oil deforestation and tropical forest loss claim the findings strengthen the argument that the Indonesian Government’s anti-deforestation legislation needs strengthening.

An article published in the journal ‘Science’ has said that efforts by countries and companies to achieve ‘zero net deforestation’ may be having the unintended effect of rainforests being replaced by less valuable plantations. As the approach does not distinguish clearly between the different values of replanted areas and natural forests, it means some countries are guilty of replacing their native forests with exotic species. A more favourable way of protection would be for companies, states and other groups to set separate reduction targets in forest loss and for reforestation efforts.

Google Earth has helped to create a new high-resolution global map of forest loss and gain, with a resolution of 30m. In the twelve years that the map spans (2000 – 2012), the Earth lost enough trees to cover the UK six times. It isn’t all bad news however - Brazil cut their annual forest loss in half between 2003-4 and 2010-11.

Jakarta, 3 September 2013 - The palm oil sector was the single largest driver of deforestation in Indonesia between 2009-2011, accounting for about a quarter of the country’s forest loss, revealed Greenpeace International in new mapping analysis published today. The analysis shows that significant deforestation took place in concessions currently owned by members of the palm oil industry’s largest sustainability organisation, the Roundtable on Sustainable Palm Oil, including companies such as Singapore-based Wilmar International. More damning is the revelation that RSPO concessions accounted for 39% of the fire hotspots on palm oil concessions in Riau during January-June 2013.

"The RSPO wants its members to be industry leaders in sustainability, but its current standards leave them free to destroy forests and drain peatland. Year after year, Indonesia's forest fires and haze wreak havoc on the region, and the palm oil sector is a main culprit. While RSPO members might have no-fire policies, the peatland they have cleared and drained is like a tinderbox – one spark is all it takes," said Bustar Maitar, head of Greenpeace International’s Indonesia Forest Campaign.

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.

A new WWF report warns that the Greater Mekong subregion in Southeast Asia risks losing more than a third of its natural forest cover in the next two decades at current rates of deforestation. The region, which is host to vital freshwater systems and forests depended upon by iconic species and a huge human population, is threatened by dam development, poaching and timber theft. The local governments have also given away large concessions to mining companies and plantation owners in designated protected areas.

MPs and policymakers from 33 of the world’s major economies gathered at the first GLOBE Climate Legislation Summit in London. The Summit concluded with a pledge which recognises that forest loss contributes approximately 17 per cent of GHG emissions each year and commits the legislators to promote and advance the REDD+ mechanism in their own countries. REDD+ offers forest nations access to new finance in return for the development of effective and independently assessed forest protection schemes.

The Google Earth Outreach team has awarded a grant to Eyes on the Forest and WWF to host, store and manage map data on Sumatran rainforest. The tool will incorporate a number of layers including forest loss over time, species distribution, conservation intervention priority areas, restoration priority areas, degraded lands and government protected areas. Eyes on the Forest and WWF hope that the data can be used to urge decision-makers to take steps to protect natural forests.
