Residents of Canada and other northern circumpolar countries are concerned with the scenarios of climate change since Global Circulation Models predict that global warming over the next 30-50 years will be most evident in the northern regions (Bolin et at. 1986; Roots 1989;…

Studies on the radionuclear contamination of forests caused by the Chernobyl disaster of 1986 show that as of the year 1992, in the Bryansk Region, 84% of the radionuclides (averaged over all the forest types examined) have been concentrated in the forest fuels of soil cover and…

Tropical forest felling can be for the purpose of traditional shifting cultivation, after which forest is re-established, or for permanent land-use change, which is defined as deforestation. Recent decades have seen a dramatic increase in tropical deforestation caused by slash-…
