Transcript of WATER Supply-Sketch
some countries in South America Extremes of rainfalls will be worse, resulting more floods and droughts in poor regions where and rapid urbanization Low Income High Population growth Changes in water availability will have Economy-wide impacts The wealthy are paying far less for the water than most of the poor in the world. For example:
“If you live in a slum in Manila, you pay more for your water than people living in London.” Why is that?
Due to privatisation of water resources:
Big companies own and operate water systems in the world, which brings to them $200 billion a year Therefore PRICES
have risen Result:
Most of the poor nations do not have access to water
If you don’t have money to buy it, you will have little water or none at all. How big is this problem? 1.1 billion people in poor countries have little access to water
2.6 billion have no access to sanitation
Lack of water is related to poverty:
More than 660 million people without sanitation live on less than $2 a day, and more than 385 million on less than $1 a day
1.8 million children die each year as a result of diarrhea
443 million school days are lost each year from water- related illness
Millions of women and children spending several hours a day collecting water
1.8 billion people who have access to a water source within 1 kilometer, but not in their house or yard, consume around 20 liters per day. What is the Human right to water
What does it mean All people are entitled to have:
Clean and Safe water
It must be:
acceptable for the people Governments are responsible: Make sure these services are delivered to all ! Governments have to implement these rights Water is a public good, not a commodity. The human right to water places certain responsibilities upon governments to ensure:
"sufficient, safe, accessible and affordable water, without discrimination"
Governments are expected to take reasonable steps to avoid
a contaminated water supply
there are no water access distinctions amongst citizens Do you think water services should be for free ? Human right means:
water and sanitation must be affordable for all In some countries water services are paid for
in others through charges
or through a mix. What can organizations do?
a social tariffs It will encourage people to be
not spoil drinking water for spraying the garden or cleaning the car Does the human right to water help the poor and people that are not connected to a system The human right to water obliges governments to ensure that everybody has water and sanitation. Water Demand for Energy to Double by 2035 The global increase of coal power will drive the largest share of water consumption for energy use through 2035.
The amount of fresh water for world energy production will 2X within the next 25 years Water consumed for energy production would increase
from 66 billion cubic meters to 135 billion cubic meters annually by 2035 Oil and natural gas production together would account for 10 percent of global energy-related water demand in 2035
"Energy and water are tightly connected" "It takes a great deal of energy to supply water, and a great deal of water to supply energy. With water stress spreading and intensifying around the globe, it's critical that policymakers not promote water-intensive energy options." Coal power is increasing in every region of the world except the United States by 2017.
These advanced plants have some environmental advantages:
They discharge much less heated water into rivers and other bodies of water, so aquatic ecosystems are protected. The surest way to reduce the water using for electricity, would be move to Alternative fuels Renewable energy Wind power Solar power Natural
gas power Have minimal water needs While providing 23 percent of today's electricity, use just 2 percent of today's energy water consumption Gas plants "Water is an extremely precious resource"
Water and the world's people are unevenly distributed
Some areas have huge reserves other areas face critical shortages
3 categories of water use:
Industrialized countries: Germany, Belgium High industrial water consumption
Australia most water for domestic and agriculture
in less economically developed countries water supply is the most important
of all environmental issues
One of the main issues:
overuse wasteful, in the long term unsustainable It is 4X bigger than the Hoover Dam's Lake Mead What we need do to reverse this crisis? Make 20 litres of clean fresh water for each person in the poor countries Governments must make clean water and sanitation and provide funding for development projects Governments and community groups must work together to devise locally appropriate solutions to water and sanitation problems. Water changes everything Thank you for your attention!
