As opposed to meteorological drought, which is a result of only weather and climatic conditions, hydrological drought is caused by lack of precipitation (rain and snow) over longer periods, and a greater demand for water in a given region than is available. Droughts can affect tree productivity, with loss of leaves and reduced canopy cover affecting nutrient cycling, and the amount of . Some preventative measures include installing anefficientirrigation system that reduces the amount of water lost to evaporation, storing water in ditches along fields, regularly monitoring soil moisture, planting crops that are more drought-resistant, and rotating crops to allow water in the soil to increase. 9 Easy April Fools' Pranks for Kids That'll Get Everyone Laughing.

Sometimes how much water humans consume, and the timing of that consumption, factors into how much water is available at a later date for people, plants and animals. Conditions continue to be critical in the area due to drought, overpopulation, failing crops, and high food prices. When forests are cut, there is less water evaporating which in turn reduces the amount of clouds that are formed. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Temperature extremes and erratic rainfall patterns associated with climate change are affecting food production and infrastructure critical to food distribution, which in turn directly impact nutrition outcomes. Sometimes, drought conditions can exist for a decade or more in a region. "We found that a number of factors can make children resilient to droughts, such as good governance, nutritionally diverse crops, higher levels of imports per capita, overall crop production, and irrigation," explains study lead-author Matthew Cooper, who started this work as part of the 2018 IIASA Young Scientists Summer Program.
