This document discusses drought, its causes, effects, and suggestions for prevention. It defines drought as a period of below average precipitation resulting in water shortages. The causes of drought include deforestation, global warming, excess water use, and lack of precipitation. The economic, environmental and social impacts of drought are outlined, such as losses to agriculture, wildlife habitat destruction, and health problems. Suggestions to prevent drought include stopping deforestation, xeriscaping, reducing pollution, saving water through conservation methods, using drought resistant crops, and advanced irrigation systems. Artificial glaciers created using pipes and cold temperatures are also mentioned as a method used in India to harvest water.

5. What is Drought….?
• A drought is a period of below-average precipitation in a given region,
resulting in prolonged shortages in the water supply, whether
atmospheric, surface water or ground water.
• Droughts is not when there's no rain at all. But actually, they can
happen when there's less rain than people thought there would be.
• Droughts occur when a long period of abnormally dry weather leads to
a severe water shortage.

Impacts

Impacts
Social Impacts

13. Economic Impacts
• Farmers may lose money if a drought destroys their crops.
• More money needed for Irrigation, feed and water for their animals.
• Businesses that depend on farming (Industries).
• Businesses that sell boats and fishing equipment .
• Power companies that normally rely on hydroelectric power.
• The power companies' customers would also have to pay more.
• Water companies may have to spend money on new or additional
water supplies.
• People might have to pay more for food.

14. Environmental Impacts
• Losses or destruction of fish and wildlife habitat.
• Lack of food and drinking water for wild animals.
• Increase in disease in wild animals, because of reduced food and water
supplies.
• Migration of wildlife.
• Increased stress on endangered species or even extinction.
• Lower water levels in reservoirs, lakes, and ponds.
• More wildfires.
• Wind and water erosion of soils.
• Poor soil quality .

15. Social Impacts
• Anxiety or depression about economic losses caused by drought.
• Health problems related to poor water quality.
• Health problems related to dust.
• Malnutrition
• Loss of human life.
• Reduced incomes.
• People may have to move from farms into cities, or from one city to
another that may lead to war for food and shelter.
• Fewer recreational activities.

16. How to combat Drought…?

17. What should we do to cope with Drought…?
• Stop cutting trees and plant more
• Xeriscaping
• Reduce Pollution
• Save water

18. We can save a lot of water doing simple
tasks…!
• Turning off the water while you brush your teeth can save more than
100 gallons of water a month.
• Recycle Water: gray water (waste water that is treated and cleaned) to
water golf courses and city parks.
• Tossing extra water to plants not in vain
• Research has shown that drip tape uses 30-50% less water than
overhead irrigation.
• Lawns and gardens require only 5 millimeters of water per day during
warm weather. Less is needed during spring, fall, or cool weather

19. Turning off the water while you brush
your teeth and shaving can save more than
100 gallons (378 L.) of water a month.
Do the same while taking Bath…!

20. Cont....!
• Understand the water scheduling needs of your crops.
• Conservation tillage
• Conservation practices that reduce runoff and encourage infiltration
• Monitor soil moisture
• Plant species and varieties of crops that withstand dryness, hold water,
and reduce the need for irrigation.
• Mulching
• Water during the cool part of the day, in the morning or evening.

21. Cont....!
• Drought resistant varieties
• Advanced irrigation system to save water
• Planting trees that use less water
• Educating our Farmers to use all the techniques to save water
• Rain harvesting

22. Artificial Glaciers
The 'ice stupa' are artificial
glaciers built at lower
altitudes using pipes, gravity
and cold temperatures.
It was the idea of Sonam
Wangchuk, an engineer from
Ladakh, in the Jammu
region of north India.

24. If they
can do it
why can’t
you…?
Thank You
