Influence of Temperature and Precipitation Changes on Desertification
Authors: Kukuri Tavartkiladze, Nana Bolashvili
Abstract:
The purpose of this paper was separation and study of the part of structure regime, which directly affects the process of desertification. A simple scheme was prepared for the assessment of desertification process; surface air temperature and precipitation for the years of 1936-2009 were analyzed. The map of distribution of the Desertification Contributing Coefficient in the territory of Georgia was compiled. The simple scheme for identification of the intensity of the desertification contributing process has been developed and the illustrative example of its practical application for the territory of Georgia has been conducted.
Keywords: Climate change, aridity, desertification, precipitation.
