Sustainable Development

Sustainable Development

• “Meeting the needs of today’spopulation, without harming the abilityof future generations to meet their ownneeds”.

OR

• Sustainable development is a pattern ofresource use that aims to meet humanneed while preserving the environment,so that these needs can be met not onlyin the present, but in the indefinitefuture.

• Renewable energy sources needto be found that will last foreverwithout contributing to theGreenhouse effect.

Renewable Energy or sustainable energy

• Renewable energy sources,such as sun and wind aresustainable, as they will neverrun out.

Non-Renewable or non-sustainable

• Fossil fuels are non-sustainable asthey take so long to reform that theycan not be replaced once they runout.

Kyoto Treaty

• The Kyoto Treaty was drawn up in 1997 in Japan, to make countries promise to reduce carbon emissions.

• The USA did not sign up as they said it would cause a drop in the standard of living.

This treaty made countries use more renewable energy such as:

WIND ENERGY

Which turns wind into electricity and are usuallyfound together in wind farms.

Hydro Electric Power (HEP)

• Large amount of water are forcedthrough turbines, which are connectedto the generators that produceselectricity.

SOLAR ENERGY

• The Sun energy is used to produce orconvert into electricity and also used toheat water

How we can reduce carbon emissions?

We can reduce carbon emissions bythe way travel, instead of using carwe can use public transports, cycle,or walk.

TAKE A LOOK WHAT PEOPLE HAVE DONE OR WE HAVE DONE!!

As a student how we can live sustainable lives!

• Turn off lights, television, computerand other appliances when you leaveroom.

• Walk, ride a bicycle or take publictransportation whenever possible.

• Keep your room’s curtains closed during hottest part of the day.

• Use energy savers instead of Bulbs and tube lights.

Why Water is Important?

Why water is important?

• Life on earth began with water.

• 70% of animals and plants arecomposed of water.

How we can make our life more sustainable?

• Turn off or close the water while you brush your teeth.

• Fill your glass with only what you will drink.

Why Agriculture is important?

What does agriculture provide?

• Food

• Fiber (Clothing)

• Fodder ( grain for livestock)

As a student you can also practice….

• To use both sides of notebook papers.

• Use cloths bags instead of paper bags and other material bags.

Sustainable Development :

a brief overview

• a kind of development that

“meets the needs of the

present without

compromising the ability of

the next generations to

meet their own needs.”

concern with extraction of

resources while at the same

time allowing the

environment to replenish

itself

• . The goal is to ensure that there will not come a time when development will be halted due to lack of naturally occurring materials as a result of environmental degradation.

• The issue of sustainability

can be divided into three

constituent parts:

environmental sustainability,

economic sustainability and

sociopolitical sustainability.

Scopes and definitions:

Environmental Sustainability

We seek equilibrium between the

amount and the processes of

extractions with the ability of

the environment to tolerate it

without sliding into a point

where there will be an

irreversible slide in ecological

balance.

• The environment from which we extract food and raw materials is more often than not disturbed, the tip of ecological balance moved over a long period of time into point where there is a steady degradation until such time when it can no longer support itself, hence dying out and denying us a steady source of much needed materials in the future.

• An ‘unsustainable situation’

occurs when natural capital (the

sum total of nature's resources)

is used up faster than it can be

replenished

• Theoretically, the long-term

result of environmental

degradation is the inability to

sustain human life. Such

degradation on a global scale

could imply extinction for

humanity.” – wikipedia

Economic Sustainability

• Economic sustainability refers

to the ability of the economy to

supply the demands of the

market with rooms for profit to

ensure a steady growth over a

period of time.

Economies are measured through this:

• Gross domestic product : the

total financial value of the final

goods and services rendered in a

country over a one-year period.

• Positive growth is indicated by an

increase in the GDP over the two

year period while a negative

growth is indicated by the

opposite.

Environmental sustainability

Sociopolitical Sustainability

• Man is said to be a political animal. (Aristotle). Anything that has a power relationship can be considered as political.

• Although there is no direct cause and effect relationship between environmental sustainability and the sociopolitical scene, it is essential to look at the power structures in given societies, even in the global level, to understand the policies implemented in certain areas, with regards to development sustainability.
