In North America deforestation was done for various reason, initially ranching cattle and agricultural needs. Similarly, in South America Amazonian forest has been destroyed for soy and other plantations for cattle. British invaders destroyed many south Asian and Eastern African forest for Coffee and Tea cultivation. How about the effect of industrialization and irrigation schemes?, Europe and other parts of Asia?
In Argentina we have witnessed in recent years a brutal process of deforestation in the north of the country for sowing soybeans. The federal government not only does not regulate these activities and covertly promotes them. There are already several million hectares in irreversible degradation (water and wind erosion).
2 factors one could be natural disasters like fires and two deforestation as a results of direct human actions. first, I recall there were huge uncontrollable fires in Australia's forests and in one of the European countries caused by the increase in earth's temperature 2,3 years ago all over the news. I guess this kind of huge fires as natural disaster end to deforestation too.
Also between 2005 and 2008, the deforestation of Rio's urban rain forest doubled compared with the previous three years so the Rio's state government decided to build a huge wall around the slums to limit them so they could not expand and deforest more to build themselves houses. http://www.theguardian.com/world/2009/apr/01/rio-slums-walls-deforestation
