Water scarcity or water crisis or water shortage is the deficiency of adequate water resources that can meet the water demands for a particular region. Variations in weather oscillations between wet and dry periods can result in periods of drought, increasing population demands can result in overuse, and continued multiple uses of water resources for industry, irrigation, drinking water, and wastewater can reduce the usability of the water resource for one or many of its needed uses.
The sources of water pollution include pesticides and fertilizers that wash away from farms, industrial and human waste that is directly dumped into rivers without treating it in water treatment plant. Oil spill on the ground, waste water leakage from landfills can seep underground and may pollute the groundwater making it unfit for human consumption.
The consequences of scarcity will be more drastic in arid and semi-arid regions. Water Management Water management by the use of regulations and policies can help reduce water scarcity.
