Drought Dynamics in the Nile River Basin: Meteorological, Agricultural, and Groundwater Drought Propagation

Zemede M. Nigatu,
Wei You,
Assefa M. Melesse

Abstract: The Nile River Basin (NRB) has experienced a notable rise in drought episodes in recent decades. The propagation of meteorological, agricultural, and groundwater drought dynamics in the NRB was investigated in this study. The following drought indices examined the correlation and propagation among meteorological, agricultural, and groundwater droughts. These are the standardized precipitation evapotranspiration index (SPEI), soil moisture index, Gravity Recovery and Climate Experiment, and GRACE Follow-On (GRA… Show more

“…However, due to the influence of human activities, the natural propagation chain of drought is becoming increasingly inapparent [8,9]. For example, reservoirs can store excess water during the wet season for use in the dry season, which means that meteorological drought may not necessarily lead to hydrological, agricultural or socio-economic drought [10,11]. To be more specific, meteorological drought occurs naturally and is scarcely affected by human activities.…”
