Researchers at University of Tehran Publish New Data on Agriculture (Investigation of Vulnerability and Spatial Analysis of Drought Risk in the Agricultural Sector in Iran): Agriculture

2023 JUN 23 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Current study results on agriculture have been published. According to news reporting from the University of Tehran by NewsRx journalists, research stated, “The nature of the drought is multidimensional and dynamic, and drought risk management plays a vital role in studying drought risk and vulnerability. Iran is always facing this meteorological phenomenon by being in the middle latitudes.”

Our news journalists obtained a quote from the research from University of Tehran: “Drought risk is defined as the risk index and vulnerability index function. In this study, vulnerability index with physical components including altitude, water system, land use and socio-economic components, the ratio of net production to total production, population density in agriculture, population density, the ratio of rainfed land to total land and number of livestock (1000 heads Per square meter) using standardized fuzzy membership functions and criteria, and each is given a specific weight according to the AHP method. All the maps are combined, and the map of land vulnerability to drought is obtained. According to the results, the southern, southeastern, and central regions are relatively less vulnerable to drought. As we move west, north, and northeast of the country, the number of vulnerabilities increases, the causes of which can be significantly affected by the characteristics. He knew the climate and physics of these areas. Finally, the drought risk map was drawn with the SPI index for 12 months, and after weighing and converting it into a fuzzy map, it was combined with the vulnerability index map.”

According to the news reporters, the research concluded: “The drought risk map indicates the prevalence of relatively high drought risk in a large area of Iran. With the help of these maps, it is possible to develop micro or macro development plans, especially in the agricultural sector for each part of the country.”
