Global Water Shortage
Transcript of Global Water Shortage
WATER SHORTAGE? Situation within all or part of the district when insufficient water is available or lack access of safe water to meet the present and anticipated needs . WHY IS WATER SHORTAGE
A GLOBAL ISSUE? Increasing demands on limited water supplies KEYPLAYERS EFFECTS SOLUTIONS CHALLENGES By 2015, nearly half the world's population-more than 3 billion people-will live in countries that are "water-stressed" (United Nations Global Issues, n.d.) 1 in every 9 people Lack of access to clean water and sanitation kills children at a rate equivalent of a jumbo jet crashing every four hours. 1)GROWING
AGRICULTURE HUNGER DISEASES Outbreak of Cholera WAR &
CONFLICT Rising regional tensions over shared river basins UNWILLING TO
MAKE CHANGES Most may feel that they their actions will not make any difference PARTICIPATION Conducting campaigns to promote awareness of global water shortage COST Desalinated water costs maybe 15 times more than regular water CHANGE LIFESTYLES American may take only 5 minutes of shower, but the amount of water used during this 5 minutes will already be much more water that the average person in a developing country slum uses for an entire day (Canadian and World Issues, 2012) Motivate New Behaviours Create Awareness At each 8 seconds, a child dies because of a disease transmitted through the infected water. Half the world's hospital beds are occupied by people suffering from water borne diseases People are drinking contaminated water Non-state actors, notably terrorists and other extremists, may also seek to sabotage dams and other infrastructure The problem with creating new water supplies in rural areas is not that we lack the technology to treat unsafe water or to drill water wells in remote locations Organization and funding have been lacking to implement and sustain true state-of-the-art water supply equipment in remote locations Implementing changes to improve needs money to make it work. Without money, it would not go far. Organizing water campaigns needs capital Improving agriculture Invest money on water saving products Global
Cooperation Maximum effort from the people is needed to improve water shortage People to lead and
make changes "Making it happen" "Making it to reality" People will then go hungry and become weak In China, 1.2 billion of the people depend on irrigated land to produce 70% of grains (Sircus, 2008) Without water, crops and livestock wither and die (Patrick, 2012) Local governments worldwide are increasingly distrusted over water allocation Instability in these societies, protests and more crime May work to scare off foreign direct investment in these countries Broad reduction in production ECONOMIC
DOWNTURN 40 % of the world population lives on rivers crossing several countries, like :
Brahmaputra, Indus and Mekong Each country wants to use as much water as possible, a fact that triggers issues NGOs GOVERNMENT CITIZENS COUNTRIES CONCLUSION The world faces an unprecedented crisis in water resources management, with profound implications for global food security, protection of human health, and maintenance of all ecosystems on Earth. Those effects will continue to snowball until a practicable solution is implemented. Looking at the situation now, it would be inconceivable to end with a practical answer. Water is life's mater and matrix, mother and medium. There is no life without water. Clean water would provide people with the opportunity to fulfill their lives to the fullest. This leads to new potential, new hope for a better tomorrow and a new life. Security Council “Looking into the future, by 2015, nearly half the world's population-more than 3 billion people-will live in countries that are "water-stressed"-having less than 1,700 cubic meters of water per capita per year-mostly in Africa, the Middle East, South Asia, and northern China.”
- John C.Gannon (Gannon, 2001). By 2025, 1.8 billion people will live in countries or regions with absolute water scarcity and two-thirds of the world population could be under stress conditions. 1)Growing Population
--Population doubled over past 40 years
--Water usage quadrupled
--Amt. of water on Earth stay the same!
--By 2025, world population increases to nearly 8 billion
(especially developing countries e.g. Africa)
Increasing demand for freshwater in rapidly expanding urban centres -->
Shared river basins & underground aquifers more heavily drawn->increasing freshwater stress 1)Growing Population *An average person uses about 123 gallons (466 liters) of water daily. Some individual household activities and the amount of water they consume are listed below: 1 4 2)Agriculture & Irrigation Usage
Largest consumers of water (100 times more than personal needs)
Global middle class will increase from 1.8 to 4.9 billion by 2030.
More wealthier people More meat consumed More energy and water-intensive agriculture for raising of livestock & feed grain
480 million ppl consume grain produced with unsustainable use of water 2)Agriculture & Irrigation Usage 2) Agriculture & Irrigation Usage 1000 tons of water to grow 1 ton of grain
15, 000 tons of water to produce 1 ton of beef
Grain exporters are exporting water
e.g. US annual grain exports: 90 million ton of grain= 90 million tons of water
Even exceeds 67-billion ton annual flow of the Missouri River! 2 3)Agriculture & Irrigation Usage 3
Pesticides & fertilisers used in agriculture
Oil & grease from roads
Pet & farm animal waste
Decaying plant material
Falling septic tanks
Sewage treatment plants
Municipal wastewater treatment plants 3) Pollution of Freshwater China:
80% of degraded rivers that no longer support fish
. Yangtze River contaminated with 40 million tons of industrial waste and raw sewage daily
Yellow River cannot be used for irrigation due to over-pollution 3) Pollution of Freshwater
Do you know…
2 million tons of sewage and industrial and agricultural waste discharged into world’s water daily = weight of entire human population of 6.8 billion people!
amount of wastewater produced annually is about 1,500 km
Cube, 6 times more than the water in all the world’s rivers 3) Pollution of Freshwater 3 3)Pollution of Freshwater CAUSES US: 500 million tons animal waste per year in farms. 60% of coastal rivers & bays moderately to severely degraded by nutrient runoff. ~11 million gallons oil enters water from streets & roads= Exxon Valdez oil spill! European continent:Rainfall filled with toxic pesticides that’s dangerous to drink
