The Problems:The two major problems that affect the amount of available fresh water are the growing Population and resulting Pollution
First, lets take a look at…
THE GROWING POPULATION

"Nearly all of world population growth is now concentrated in the world's poorer countries, even the small amount of overall
growth in the wealthier nations will largely result from immigration.”
- Bill Butz, PRB’s president
"The differences between Italy and the Democratic Republic of the Congo illustrate this widening demographic divide, on one side are mostly poor countries with high birth
rates and low life expectancies. On the other side are mostly wealthy countries with low
birth rates and rapid aging.”-Mary Mederios Kent, co-author of this year’s

Issues For Under-developed Countries
– limited financial means– inadequate political & managerial resources
– 18 percent of the population is undernourished

Issues for Highly-developed Countries
• Population uses too much water
• Industry causes pollution

Population Projections in UDCs
• Projected to increase significantly• Most growth of world population will take
place in UDCs• 2050 projection:
– Africa= 1,766,000,000– US=392,000,000

Example of HDC-JapanBreakdown of Japan’s Water Use
Annual Use– 16.2 billion m3 for domestic use– 12.1 billion m3 for industrial use– 55.2 billion m3 for agricultural use
Groundwater– 3.7 billion m3 for domestic use – 3.8 billion m3 for industrial use– 3.3 billion m3 for agricultural use

Japan; Mineral Water
• The total amount of domestic production and import of mineral water increased by 13 times from that in 1990 to approximately 2.3 billion liters (in 2006)
• price is about 550-fold of tap water

![Page 21: Global Water: Our Limited Resource Erika Shaid, Aria Amrom, Sara Goldstein, Samara Gordon](https://reader035.vdocument.in/reader035/viewer/2022062409/56649f585503460f94c7e1f1/html5/thumbnails/21.jpg)
Global Water’s Population Control Wish
• “There should be access to birth control education and materials so people in developing countries have that as a choice. They are not available today.”
-Ted Kuepper of Global Water

Example for Population Control
• One Child Policy:
-The population control policy of China
-Restricts number of children married urban couples can have to 1

Point Source Pollution
• enter a waterway through a discrete conveyance like a pipe or ditch
• U.S. Clean Water Act
http://en.wikipedia.org/wiki/Water_pollution
![Page 29: Global Water: Our Limited Resource Erika Shaid, Aria Amrom, Sara Goldstein, Samara Gordon](https://reader035.vdocument.in/reader035/viewer/2022062409/56649f585503460f94c7e1f1/html5/thumbnails/29.jpg)
Non-point Source Pollution
• Contamination that does not originate from a single discrete source
• Example: leaching out of nitrogen compounds from agricultural land which has been fertilized
• Urban Runoff
http://en.wikipedia.org/wiki/Water_pollution
![Page 30: Global Water: Our Limited Resource Erika Shaid, Aria Amrom, Sara Goldstein, Samara Gordon](https://reader035.vdocument.in/reader035/viewer/2022062409/56649f585503460f94c7e1f1/html5/thumbnails/30.jpg)
Ways to Prevent Water Pollution on a Local Level
• Recycle• Environmentally friendly household products• Natural fertilizers and pesticides• Conserve water by turning off the tap when running water is not necessary• Reuse Automobile oil

Global Water’s Solutions
• More access to safe water supplies is more important than conservation in the developing world
• GW spreads awareness through website and through students and others
• Use literature to give presentations to students• Funding projects in Nicaragua, Guatemala, Peru, Kenya,
Botswana

EPA’s Solutions
• regulating point sources that discharge pollutants
• Works with state and local authorities – monitor pollution levels in U.S. water– status and trend information
• variety of ecosystems

• Marine Protection, Research, and Sanctuaries Act (1972)
• Safe Drinking Water Act (1974)
• Federal Insecticide, Fungicide, and Rodenticide Act, as amended in 1988

Millennium Development Goals
• 2000 UN Millennium Summit– 189 world leaders from rich and poor countries
– eight time-bound targets to end extreme poverty worldwide by 2015
http://www.un.org/millenniumgoals/
• Many high-level conferences• need for international cooperation • address the issue of access water and sanitation

Global Conference
• Leaders from each country gather together to establish global goals of reducing water pollution, reducing population, and sharing water equally
• The conference will be divided into three parts: education, suggestion, and goals/future
![Page 37: Global Water: Our Limited Resource Erika Shaid, Aria Amrom, Sara Goldstein, Samara Gordon](https://reader035.vdocument.in/reader035/viewer/2022062409/56649f585503460f94c7e1f1/html5/thumbnails/37.jpg)
Education

Suggestions
• Bring in different organizations’ plans, use these as models
• Teach countries methods of sustainability, conservation, lessing pollution, and desalination
![Page 39: Global Water: Our Limited Resource Erika Shaid, Aria Amrom, Sara Goldstein, Samara Gordon](https://reader035.vdocument.in/reader035/viewer/2022062409/56649f585503460f94c7e1f1/html5/thumbnails/39.jpg)
Goals/Plans for the future
• Meet in 5 years to view progress
• Yearly updating report
• Each country needs to create a proposal of what they are going to do using the suggestions that we give

UN Resolution
• Through a series of goals, resolutions and declarations adopted by member nations of the United Nations, the world has a set of commitments, actions, and goals to fix the problem of decreasing fresh water availability
