Fire effects on ecosystems

Sand-dust storm (SDS) refers to extreme events causing massive loss and damage to the social, economic, and ecological systems. SDS disaster risk assessment is important for SDS disaster reduction, especially from the regional perspective to the global scale. Based on wind speed and visibility of 9435 meteorological stations from 1982 to 2011 provided by the global surface synoptic timing data set, using kinetic energy as indicator of SDS intensity, regional aridity as indicator of background environment, and GDP, population and livestock as indicators of exposures, the global SDS risk is evaluated in terms of disaster system theory. The results show that high values of affected population risk are mainly distributed in the southeastern, southwestern, and northwestern regions of the Saharan desert, northern and southeastern regions of Rub Al Khali desert, the areas surrounding the Thar desert in western India, Iran and Turkey's desert areas, the Taklimakan desert, the farming-pastoral region in China and the Mongolian Gobi Desert, wide areas in the southwestern American deserts, the central Great Plains and the northern regions of Mexico, western coast of south America, and northeastern Brazil. The affected risk of GDP is relatively lower than population risk in Africa, and higher than population risk in coastal areas of the Black Sea, the Caspian Sea, and Bohai coastal area. High values of the affected livestock risk are mainly distributed in adjacent areas of the Saharan desert, south Arabian desert, the Thar desert, the Iranian desert, Turkestan desert, the Taklimakan desert in China, the Gobi desert in Mongolia, central and south section of Australia, surroundings of North American desert, central Great Plain, northern Mexico and west coast and northeastern parts of South America.
