What is forest fire?
The forest fire is the burning of tropical, temperate and boreal forest either by natural fire or man-made fire and is related to land clearing and deforestation. Natural forest fire includes an unplanned burning of forest due to lightning, while human-induced forest fire results from the unauthorized burning practice of forests for attaining farmland. In spite of low commitment of boreal forest in worldwide biomass burning emission, there is 10-folds increase in the extent of boreal forest burning in recent year. The burning of forests destroys an important sink for atmospheric carbon dioxide. Usually, forest burning is widely practiced especially in Central and South America for converting large scale moist tropical forest to rangeland and agriculture, arson negligence and for hunting purpose. Forest burning is another important route for diminishing the catastrophic forest fire risk.

Is forest fire a problem in Europe?
Forest fires (the term used in Europe to designate the unwanted fires burning forests and wild lands) constitute a serious problem throughout Europe. Although there exists a sharp gradient from the South to the North, in terms of fire regime (e.g., contributing and causing factors, fire frequency and area burned, fire behavior), no country is exempt. All face growing risk from increasing population density, creeping urban sprawl from incursion into the wildland urban interface (WUI), and from changes in land-use patterns that conflict with societal and ecological protection. Changing climatic and weather conditions are exacerbating these problems. This chapter discusses this complex phenomenon in Europe and highlights the challenges to managing forest fire risk in ways that reconcile social and economic development, environmental concerns, and living with forest fires in a sustainable and dynamic equilibrium.
