Drought monitoring and early warning systems
A drought can be defined in several ways. A meteorological drought, for example, occurs when rains do not transpire, whereas a hydrological drought occurs when a lack of rainfall continues long enough to empty rivers and lower water tables. Agricultural droughtbegins when a lack of water kills crops and livestock, affecting locals’ survival.
The timing of declaring a drought can often be very subjective and highly political. Forecast mechanisms require quality data and local knowledge to understand how dry conditions will impact water and food supplies. Unfortunately, these predictions are often unreliable and action is not taken until it is too late.
With more research and collaboration, early warning systems could reduce hunger and distressed migration as a result of drought. An Early Warning System (EWS) provides timely and effective information to facilitate action to avoid or reduce the risk of droughts and prepare for effective response. Numerous natural drought indicators must be monitored routinely to determine the onset and end of drought and its spatial characteristics. Although all types of droughts originate from a precipitation deficiency, it is insufficient to rely solely on this climate element to assess severity of drought. Effective drought early warning systems integrate precipitation and other climatic parameters with water information, such as stream flow, snow pack, groundwater levels, reservoir and lake levels, and soil moisture, as well as a comprehensive assessment of current and future drought and water supply conditions. Local knowledge systems, including traditional knowledge of farmers and pastoralists should also be incorporated into the information system (Handbook of Drought Indicators and Indices, 2016).

drought is a natural calamity with occur when
soil doesn't get enough water . This affect a huge area
Drought decreases the quality of soil which led to the less production of crop and this made led to food insecurity for the peoples in the affected area
govt takes various steps to get rid of drought like -
- planting more and more trees
- removing the main cause of drought that is climate change
-preparing camps to provide food and water to the peoples
