Impact of shelter forest belts of Robinia pseudoacacia L. on spread of fires and the damage caused by them was investigated in arid agroforestal landscapes of Russia. A mathematical model for arid regions of the world was obtained. According to the model, the area of fires in agrarian lands in habitats with forest shelter belts of the 1st class life-state varies by an average of 1.22 ha/hour comparing to plantations of the 2nd and 3rd classes - up to 1.56 ha/hour. The forest belts could suffer low (a forest stand is not substantially damaged), medium (more than 10% of live trees) and severe (less than 10% of live trees) degree of damages by fire. The damage caused in this case amounts to US$ 220, 853 and 2,210 / ha. The world community has been recommended a method for fighting fires in arid agroforestal landscapes Don Fire Protection" developed at the Don State Agrarian University. A new scientific direction "agroforestry pyrology" is substantiated; agroforestal landscapes exposed to wildfires is its research object and the main task is to study the patterns of occurrence, behaviour and consequences of fires on forest-meliorated lands in order to develop fire-safe technology of protective afforestation under global climate warming."
