While most natural disasters, like tsunami, happen comparatively fast that there is little time to prepare, droughts occur relatively slowly over a period of time. No single universal word can define when a drought begins or ends. However, the influences of drought can be initially felt by the amount of annual rainfall. Spontaneously, the impacts of drought increase with the time of a drought as supplies in lakes and groundwater are depleted.
California has experienced a severe drought for four years now. The drought is characterized by very high temperatures and very low precipitation. With a high population and a deepening drought problem, competition for water between nature, farms and cities in California is acute. A future El Nino prospect presents opportunities for California to shore up its water security. Harvesting of El Nino rain water is necessary so as to ensure that California is water secure. Currently, water conservation is a priority for California residents because the state cannot afford any water wastage owing to its acute severe drought situation.
The severe California drought has impacted water use and the government is also striving to overcome the drought situation. The state government has been at the forefront of encouraging residents to cut back on their water use. In April 2015, Governor Jerry Brown ordered urban residents to cut their water use by 25 percent. Communities that record high per capita use are most affected as government authorities are forcing them to reduce their daily water use by as much as 36 percent.
