Many tropical forests around the world have been severely fragmented as human disturbance split once-contiguous forests into pieces. Previous research indicates trees on the edges of these fragments have higher mortality rates than trees growing in the interiors of forests. Researchers used satellite data and analysis software they developed to figure out how many forest fragments there are, and the extent of their edges. They discovered that there are around 50 million tropical forest fragments in the world today. When they calculated how much carbon is being released from tree death at these edges, they found a 31% increase from current tropical deforestation estimates.

Researchers from Harvard and Columbia universities in the US estimated there were more than 90,000 early deaths in Indonesia in areas closest to haze-belching fires, and several thousand more in neighbouring Singapore and Malaysia. The new estimate, reached using a complex analytical model by combining satellite data with models of health impacts from smoke exposure and readings from pollution monitoring stations, is far higher than the previous official death toll given by authorities of just 19 deaths in Indonesia. It triggered calls for action to tackle the “killer haze”.

Myanmar’s National League for Democracy-led Government announced a national logging ban, effective immediately, which will run until the end of March 2017. Satellite data shows the tree cover in Myanmar has lost nearly 5 percent (2 million hectares) from 2001 through 2014. In 2014, Myanmar enacted a ban on raw timber exports. A driving force of Myanmar’s illegal timber trade is demand from China, and Myanmar was once China’s biggest supplier of rosewood in 2013. The demand from china declined in 2015 since China’s economy slowed, and currently, China’s timber trade with Myanmar is officially suspended.

According to satellite data analysed by researchers at Michigan State University, tree cover increased significantly on about 1.6% of China’s territory between 2000 and 2010, while tree cover dropped on only 0.38% of China’s land. The researchers attributed the forest gain to China’s Natural Forest Conservation Program, which has banned logging in many of the country’s forests and set up systems to prosecute illegal logging. The NFCP also compensates businesses and households for monitoring forest health and conserving trees rather than cutting them down.

The Montagnes Blanches endangered forest has become a focus area for conservation organisations due to threats on its unique features by illegal logging. According to satellite data provided from 2000-2013, almost 50% of the intact forest landscape has been lost or degraded. Furthermore the species, woodland cari-bou within this forest is now being identified as threatened under Canada’s Species at Risk 2.

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.

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 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.

Data released this week by Terra-i, a collaborative mapping initiative, shows that deforestation in Ecuador for the first three months of 2013 was pacing more than 300 percent ahead of last year's rate. The report comes shortly after Ecuadorean President Rafael Correa killed off a proposed plan to prohibit oil drilling in Yasuni National Park in exchange for payments equivalent to half the value of the park's unexploited oil reserves.

Terra-i, a collaboration between the International Center for Tropical Agriculture (CIAT) in Colombia, The Nature Conservancy (TNC), the School of Business and Engineering (HEIG-VD) in Switzerland and King’s College London (KCL), uses NASA satellite data to detect deforestation in Latin America on 16-day basis. The system shows that between Jan 1 and Mar 7 this year, some 9,075 ha of Ecuador's forests were cleared. By comparison, 2,931 ha of forest were chopped down during the year-earlier period.
