Abstract
Drought has been one of the most damaging natural phenomena in the past decades. On the other hand, due to the complex and creeping nature of drought, it is almost impossible to determine a specific start and end time for it. Dry and wet periods are visible and expected in all climates and all seasons of the year, but sometimes a dry period leads to a drought and it affects humans (in various aspects), therefore, while every dry period cannot mark the onset of a drought, it is important to note that not every wet period signifies the end of a drought. In this study, the concept of drought and dry spells has been clearly expressed and the effect of these phenomena on humans has been discussed. To address the complexities of drought, a ten-step framework for risk management has been developed. This comprehensive guideline provides a systematic approach to drought planning and management, encompassing various facets of this challenging phenomenon.
