As a common and frequently occurring disaster, it poses a serious threat to agricultural production, the ecological environment, and economic and social development ().Therefore, research on drought monitoring techniques and assessment methods has important practical significance for the … Among various available tools, the most frequently used are probability functions‐based drought indices, such as standardized drought indices (SDI) (Erhardt and Czado, 2018 ). Drought monitoring is an essential component of drought risk management. Climate change is expected to alter precipitation patterns worldwide, potentially increasing chances for drought in places where rainfall decreases over extended periods. Drought Defined. A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. Drought is a complex and recurring natural disaster that occurs throughout the world and often has negative impacts on many sectors of society. data mining techniques can help us to monitor drought using oceanic indices as a precursor of drought. Among these, the definition of quantitative indices is the most widespread approach, but subjectivity in the definition of drought has made it very difficult to establish a unique and universal drought index. Soil moisture is a primary indicator for agricultural drought. Credit: The U.S. Department of Agriculture. The map uses five classifications: abnormally dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3) and exceptional (D4). The components of a drought preparedness and mitigation plan are the following: Prediction Monitoring Accurate monitoring and prediction of agricultural droughts helps manage them, minimize losses attributed to them, and mitigate their extreme forms, which some countries face even today. … It was developed under the Caribbean Water Initiative in 2009 (Caribbean Institute of Hydrology and Meteorology, 2010).… It is a temporary deviation of rainfall and moisture conditions from the mean, thus differing from aridity and seasonal aridity. Drought is the most complex and least understood of all natural hazards, affecting more people than any other hazard.
