Earth as water planet• Earth is often referred to as `the water planet'. • Without water, life could not exist• Earth is unique due to its abundant water - in

oceans, rivers, ponds, atmosphere, glaciers, fresh water/ground water

• Ocean Water : Most of the water on Earth, 97% to be exact, is salt water found in the oceans.

• Due to salt content, it can not be used. Process of removal of salt is very expensive.

• Groundwater: Freshwater is stored in underground aquifers. Water that enters an aquifer remains for an average of 1,400 years!

What kinds are there?

Availability

Water is essential to life on earth• 97% of the water is salt water, and

is found in the oceans of the world.• 3% of the water is fresh water on

which we depend.

Significance of water• Water is the main constituent of ecosystem & is

the basis of known life forms, including humans• It was the basis of the origin of life on our planet• Water is an integral part of life on this planet. • It is an odorless, tasteless, substance• It is essential to civil, agricultural & industrial use• Thus it is main constituent of the universe

Page 8: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Three forms of Water• Solids: When water becomes very cold and

freezes it changes from a liquid to a solid state. It has a definite form and shape.

• Liquids: When water takes the shape of its container it is in a liquid form.

• Gases: When water is seen in a vapor form and has no definite size or shape it is in a gas form.

These 3 forms are interchangeable

Page 9: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Importance of water• Organisms are composed 70%-95% of water• Transport medium for food, oxygen, and other

things needed by cells• Cellular medium within which biochemical

reactions can occur• Supportive external environment for aquatic

organisms

Page 10: 33 part 1-earthsoft-water - critical resource-basic

A precious natural resource• We use water for drinking, irrigation, industrial

purposes and energy production. Water use• Agriculture and energy production - 80%• Industry and public use - 20%Usage• As a nourisher of plant, animal & human life• A bearer of food & drinks• A prime element of industrial processes• A medium for transportation

How much water do we use?• The kitchen consumes 10% of total household

for cooking, cleaning, washing or drinking. • 15-20% of all water consumed in laundry• Nearly 50% in the bathroom, 20% of that water

is flushed down the toilet.• A slowly dripping tap can waste 20,000 liters in a

year• Evaporation is a major loss from swimming pool. • A lot of water is used in washing cars, bikes,

cycles and garages.• 20% Grey water is typically water from baths,

showers, hand basins and washing machines.

• Saltwater evaporates from sun's energy producing fresh water in clouds

• Water vapor cools and condenses to precipitation over oceans and land.

• Runoff forms fresh water lakes, streams, ponds, groundwater, and is held in soil & plants

Ground Water• Ground water is located beneath the ground

surface in soil pore spaces and in the fractures of rock formations.

• A unit of rock is called an aquifer when it can yield a usable quantity of water

Water world

• Less than 3% of the world’s water is fresh – the rest is seawater and undrinkable.• Of this 3% over 2.5% is frozen, locked up in Antarctica, Arctic & glaciers, and not available to man.• Thus humanity must rely on this 0.5% for all of man’s and ecosystem’s fresh water needs.

Page 26: 33 part 1-earthsoft-water - critical resource-basic

• Only about 2.5% of Earth's water is fresh.• ~ 2% of the Earth's water is in solid form, found

in ice caps and glaciers.• One percent of all the Earth's water in a form

useable to humans and land animals. • This fresh water is found in lakes, rivers,

streams, ponds, in the ground & as vapor in the atmosphere

• India has 16 % of the world’s population and 4% of its fresh water resources.

Water & Earth• What % of the Earth is made up of water?• What % of water is Salt, Fresh, and Frozen?• The Earth is made up of

approximately 70% water.• 97% of that water is salt

water. Very little is water that we use to drink & cook• 2% of water is frozen.• 1% of water is fresh water

Page 59: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water & Body• What % of our body is made up of water?• Human body is made

up of ~ 60-70% water• Medical source

documents that men have 60% and women have 50% water.

Page 60: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water & Blood• What percentage of blood is water?• 92% of 55% which is 50.6%• It is composed of blood cells suspended in a

liquid called blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume

Function of Water in body• Identify main functions of water in the body’s

metabolic process.• It delivers oxygen and nutrients to different parts• It removes toxins and waste from the body• Water also has other functions:• Regulates body temperature through

perspiration• Reduces friction between joints and facilitates

movement• Acts as a cushion between organs to protect• Facilitates normal functions of body processes.

Page 62: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water & Body• In what way the body lose water & How much?• A person can live without food for weeks but life

cannot last more than few days without water . • Human body is 60-70 % water. We take water

with food and drink, and lose it in urine, in sweat, and in our breath (as water vapor)

• A person loses 1.89-2.83 lit of water every day as a result of their normal body functions

• This much loss means if a person doesn't get any fluids for about three days, they will die.

• 6-9 quarts (5.678-8.517 l) of water loss would cause death.

Page 63: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water & Body• Percentage of overall water loss occurs when:

• Thirst is perceived.• Strength and endurance decrease.• Delirium and blurred vision become a problem

and you can not move.• A person dies.

Page 64: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water & Body• In one day the person loses between 2 to 3

quarts of water through their urine, sweat, and normal breathing. If a person doesn't replace that lost water, then dehydration begins to occur.

• At 1-2% dehydration, thirst is perceived. (.6-.9 quarts)

• At 5% dehydration, a person becomes hot and tired, and strength and endurance decrease. (1.5-2.25 quarts)

• At 10% dehydration, delirium & blurred vision become a problem, can not move. (3-4.5 quarts)

• At 12-20% dehydration, a person dies (6-9 q)

Page 65: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Other Water Facts• 1.2 billion people lack access to safe water,• ~one-sixth of the world's population lack access

to adequate sanitation services.• 6,000 die every day from diseases associated

with unsafe water, poor sanitation & hygiene.• Unsafe water & sanitation cause an estimated

80 % of all diseases in the developing world.• Women and girls tend to suffer the most as a

result of the lack of sanitation facilities.• One flush of a Western toilet uses as much

water as the person in the developing world uses for washing, drinking, cleaning & cooking.

Page 66: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water facts..Continued• Water use has grown at twice the rate of

population during the past century. • The Middle East, North Africa and South Asia

are chronically short of water.• In developing countries, as much as 90 percent

of waste water is discharged without treatment.• Over pumping groundwater for drinking water

and irrigation has caused water levels to decline by tens of meters in many regions, forcing people to use low-quality water for drinking.

Page 67: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Water facts..Continued• Losses of water through leakage, illegal hook-

ups and waste amount to about 50 percent of water for drinking and 60 percent of water for irrigation in developing countries.

• Floods affected more than 75 percent of all people impacted by natural disasters during the 1990s and caused over 33 percent of the total estimated costs of natural disasters.

Water and sanitation• Investments in safe drinking water and improved

sanitation show an improvement in human health and economic productivity.

• Each person needs 20 to 50 liters of water free of harmful chemical and microbial contaminants each day for drinking and hygiene.

• It’s a challenge to providing this basic service to large segments of the human population.

Learning Objectives• To understand that water is a global issue and

not just within certain countries• That lack of water is not the only issue in water

insecurity and stress• Access to sanitation is linked to poverty• Development can hinder water quality, access

and supply

Page 72: 33 part 1-earthsoft-water - critical resource-basic

Human water needs• In the US usage in gallons/person/day• A person needs about 1 gallon water/day for

hydration• Personal use - 188• Additional 657 used for irrigation, industrial use • Total per capita use is about 2000

gal/person/day• If world’s water supply were 100 liters, the

Global water situation• Estimates suggest that nearly 1.5 billion people

lack safe drinking water• At least 5 million deaths per year can be

attributed to waterborne diseases. • With over 70 percent of the planet covered by

oceans, people have long acted as if these water bodies could serve as a limitless dumping ground for wastes.

A very personal look at water• What happens to water before you drink it?• What happens to water after you dispose of it?• Approximately 57% of Canadians are served by

wastewater treatment plants, compared with 74% of Americans, 86.5% of Germans, and 99% of Swedes.

• Approximately 99% of Swedes are served by wastewater treatment plants

Asia and Pacific• 1/3 of pop’n lacks access to clean drinking water• 500,000 infant related deaths through diarrhoea• Levels of bacteria from human sources is 10x

higher than recommended levels• Agriculture accounts for 90% of freshwater

withdrawals in S. Asia• Aquifer depletion in Asia has reduced water

availability per capita by over half• Withdrawals in W. Africa far exceed natural

replacement levels

Emerging pattern• The balance between human demand and

availability is precarious• Access to clean water is not always guaranteed

when it should be a fundamental right• Pop’n growth especially in the third world mean

prospects are not good.• UN's world water development report

Millennium Development Goals• In 2000 had a target to halve by 2015 the

proportion of people without access to sustainable water supplies

• By 2005 only 12% of developing countries had managed to do this

• In some LEDC’s fresh and waste water aren’t even separated. (Cholera and dysentery)

How water is used• In the western US, irrigation makes up 85% of

all water use• 50% to grow food for livestock• 35% to grow crops

• Not sustainable…cost of water is heavily subsidized by the federal government

Page 105: 33 part 1-earthsoft-water - critical resource-basic

Key Areas-Direct Operations• Virtually all business organizations utilize water

in the production of their goods & services, the extent of use varies

• For instance, water-infrastructure companies play a direct role in working with governments and municipalities to manage water and wastewater systems.

• In other cases, water is a primary ingredient in an organization’s final product. Water is also crucial in the manufacturing or development process of many companies. In still others, water is a primary resource in the supply chain.

Page 106: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Key Areas-Direct Operations• In areas of water stress, rapid industrialization

place significant demands on water resources.• Therefore, we pledge to undertake the following

actions as appropriate & during the period1.Conduct a comprehensive water-use

assessment (audits) to understand the extent to which the company uses water in the direct production of goods and services.

2.Set targets for operations related to water conservation and waste-water treatment, framed in a corporate cleaner production and consumption strategy.

Page 107: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Key Areas-Direct Operations3. Seek to invest in and use new technologies to

achieve these goals.4. Raise awareness of water sustainability within

corporate culture.5. Include water sustainability considerations in

business decision-making – e.g., facility-siting, due diligence, and production processes.

Benefit of saving• Everyone will also get enough water to use• Save water, reduce electricity & water bills, also

reduce maintenance efforts, time & cost• Water harvesting• Utilise Grey water• Water efficient garden• Using water efficient products

• No waiting or running behind tankers• Save water and protect our environment

Page 109: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Benefit of saving• Covering the swimming pool

• Lowers the pool temperature• Decreases evaporation• Prevents debris falling on the pool surface• Reduce sunlight penetration, reduce amount

of chemicals needed to keep the pool clean. • By covering your vehicles when not in use, use

less water & efforts for washing• Water efficient gardens use plants that attract

native birds, makes it more enjoyable• A water efficient garden directs water to where it

is needed, so no problem with runoff or erosion.

Page 110: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Benefit of saving• Conserving water saves money allowing

marketing edge in a very competitive industry.• Protecting valuable water resources maintains

competitive advantage. • Enhance relationships with staff, customers and

the local community • Enhance organization’s reputation as an

environmentally responsible employer • Save on energy bills by reducing hot water

usage

Page 111: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Benefit of saving• More water available for local streams,

wetlands, and their natural inhabitants• Reducing impact on local water supplies and

systems• Reduced pumping need reduces energy costs• Decreased infrastructure requirements such as

maintenance and upgrades of equipment• Reduced environmental risks associated with

wastewater• Preparation of company for future water

restriction and increased water prices

Page 112: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Benefit of saving• Water recycling and runoff management allows

further use of water for free• Increase productivity- efficient water use leads

to greater returns per hectare.• Improve whole farm efficiency and sustainability.• Prevent deep drainage from over-watering.• Saving money through reduced water costs and

more effective use of fertilizers• Lower energy requirements for pumping less

water reduces costs.• Decreases demand on local water supply.• Allow farmers to maximize irrigated area

Page 113: 33 part 1-earthsoft-water - critical resource-basic

Making earth little softer

Benefit of saving• Increased savings through reduced water and

pumping costs• Reduced fertilizer application• Lower energy requirements for pumping• Reduced amount of drainage water and surface

runoff• Additional water for expansion or trading • Less impact on environment

What have we learnt• There is no life without water• Extremely small % of fresh & usable water is

available for human being out of total stock• That water is a global issue and not just within

certain countries• That lack of water is not the only issue, but also

water insecurity and water stress• Access to sanitation is linked to poverty• Development can hinder water quality, access

and supply• Using water carefully could minimize the

scarcity
