Global drought

About 52 percent of the United States are experiencing moderate or worse drought. Droughts can have significant environmental, agricultural, health, economic and social consequences. For example, subsistence farmers are more likely to migrate during drought because they do not have alternative food sources. Areas with populations that depend on water sources as a major food source are more vulnerable to famine. Drought can also reduce water quality, because lower water flows reduce dilution of pollutants and increase contamination of remaining water sources. We can lose a lot of water doing simple everyday tasks. Did you know that turning off the water while you brush your teeth can save more than 100 gallons of water a month? Just shutting off the faucet or fixing a leak can save a lot of water.

- General degradation in drought conditions - El Nino event.
- A worldwide weather phenomenon threatens the future of water and food supplies -global economy - Colombia, Pakistan, Somalia, Australia, China and Kenya...
The consequences of drought-induced forest die-off can be manifold for ecosystems, society, and the climate system. Tree mortality has effects that span the range of ecological organization across populations, communities, and ecosystems, and even biosphere–atmosphere feedbacks.

-The unparalleled drought in the Amazon in 2005 caused massive grief for the population who depend on fisheries. -The heat wave in Europe in 2003 has cost up to almost 40,000 lives -The Western United States continued their multi-year drought in 2005.
Global warming affects evapotranspiration—the movement of water into the atmosphere from land and water surfaces and plants due to evaporation and transpiration
Drought is expected to increase in the future as a result of climate change, mainly as a consequence of decreases in regional precipitation but also because of increasing evaporation driven by global warming
-In Australia, drought conditions continue to intensify across the continent. -In New South Wales, some areas have now gone three years without rain.
-In Taiwan, the worsening conditions have led to the implementation of water rationing in a number of cities and counties. -Brazil has been experiencing an upswing in Dengue Fever cases tied to the drought and water storage containers.
Heatwave is scourging Iran bringing temperatures to alarming heights which, combined with the lack of rainfall, created drinking water shortages and reductions.
California is slowly fading into desert land. The fight to save the state's water resources has begun at the state level. Governor Jerry Brown recently imposed a 25 percent mandatory restriction on urban water use. This takes effect in July 2015.
Current responses to drought tend to focus on short-term measures, such as temporary water conservation and efficiency improvements, water transfers, and increased use of groundwater.
We should: -Better monitor and measure water supply and uses nationwide
-Increase recycling and reuse of water -Make more strategic use of groundwater
-Reduce indoor water use through more efficient appliances, technologies, and behaviors
