Preliminary assessment of the contribution of large industries to deforestation - Dataset used for deforestation was generated by Broich and Hansen. It is an annual dataset tree cover loss between 2000-2010 - We transformed the tree loss into loss of natural forest by removing all tree loss Pixels that fell outside of the forest area in year 2000 using a 2000 forest cover Map from MoF - We then only measured the deforestation under forest areas that were developed for industrial plantations (IOPP, ITP and Mining) between 2000-2010. - Because the deforestation dataset is annual, it picks up tree fall from logging and logging roads. But, this not deforestation. This is degradation. We excluded Those degradation pixels if they fell within 700m of logging roads created between 2000-2010

1.42 million ha of natural forestLost between 2000-2010 ; 4.2% (0.42 % yr-1) In 1990-2000 about 8 million h lost (5 times higher)
