Abstract

Drought is a recurring phenomenon that can affect several sectors of life and the environment, and it can be directly linked to water scarcity problems. Based on this, Libya can be considered one of the countries suffering from recurring drought. Therefore, contributing to understanding the conditions of drought in our country will be a step towards mitigating its effects and severity. The current study focuses on the Drought Survey Index (ROI). At 8 weather stations in northern Libya, Zuwarah, Tripoli Airport, Nalut, Misrata, Sirte, Ajdabiya, Benina, Derna, during the period 1960-2010 AD, and by using the (DrinC) program, the possible evaporation and transpiration were calculated using the (Hargreaves) method as well as (RDI), and the drought maps were made using (10.3 ArcGis) using the (1W) method for the year (1971-1972).
The map clearly shows the increasing drought from the west of the country to the east, as well as the year map (2009-2010), which is the worst year of drought during the study period. The results of 128 also showed that the year (1970-1971) is the beginning of the noticeable drought in all the study stations.
Since the scale is related to rainfall and evapotranspiration (P/PET), the increase in evapotranspiration is due to the observed increase in temperature around the world, including at all study stations. From this perspective, it can be considered that the 128 method reveals the instability of the climate in the region in terms of temperature or rainfall.
