How does water shortage impact people and countries
- Domestic impact
- Increased difficulty in collecting water
- because of droughts/90% of water is used for
agriculture, leaving little for domestic use
- Women in some parts of Asia
and Africa have to walk 6km to
collect water
- Can only bring back as much as
they carry
- Water collected may be dirty
- Water-borne diseases such as cholera
- Water Rationing
- Making Water available only at
certain times of the day by cutting off
water supply
- During droughts,
government impose
water rationing to
conserve the water
supply
- Inconvenience
- Economic Impact
- Reduced Agricultural yields
- water supply decreases, crop
yield decreases
- a lot of water needed to
grow crops such as rice
- groundwater stocks
becoming depleted
- drilling deeper wells often result in drawing water from salty underground pools which poisons crops and destroys soil
- droughts
- Increased cost of industrial production
- Cost of producing and manufacturing goods
- Power plants use a lot of
water to cool parts of
generators
- During lack of water, power output decreases
- Cut in power production increases price of power
- Beverage industry also affected as they
also use a lot of water in production for
rinsing,cleaning,heating, cooling
- Political Impact (conflict over water supply)
- problems may arise when many
countries tap into the same water
resource
- one country's use of the resource
could reduce the amt available to
another country
- e.g Mekong River
- Countries that tap: Lao PDR, Vietnam, Cambodia, Thailand, China, Myanmar
- e.g Lao PDR's proposal to build the Xayaburi Dam
- Decreases flow of water downstream, thus there are many objections
- Affects the livelihood of many who rely on the river to maintain their fisheries and farmland
