The document outlines various types of resources, including potential, developed, stock, and reserve resources, emphasizing the importance of sustainable development and effective resource planning. It highlights the need for conservation due to limited availability and uneven distribution of resources while proposing methods for conservation and responsible use. Additionally, it references the Earth Summit and Agenda 21 as significant efforts in promoting environmental sustainability.

1. Potential Resources
 Resources which are
found in an area but not
have been utilized
however due to lack of
requirement.
 For example, Rajasthan
and Gujurat has enough
potential to produce
solar energy due to
cloudless sky and more
temperature.

2. Developed Resources
When resources found in a region are
surveyed by engineer and their quality and
quantity are determine for utilization, it is
called developed resource. Technology and
capital help in development of resources.

3. Stock Resources
 Material found in our environment
 satisfy many of our need
 but are not used
 Because of lack of appropriate technology.
 Exampleg:-
The water molecule consists of two inflammable
gases called H or hydrogen and O2 or oxygen that if
extracted can serve as a fuel. however we are not yet
enlightened with a proper know-how to go through
the above plan

4. Reserve Resources
Reserve is those parts of stock which can be
utilized using existing technology. But these
resources are not being used and they have
been left for future generation. They are
called reserve.

5. Sustainable Development
Development without damaging the
environment is called as sustainable
development. This development meets the
demands of present generation as well as
future generations.

6. Earth Summit and Agenda 21
Earth Summit is an
international conference
on environment. It was
held in Rio de Jeniro
[Brazil] in 1992. In the
conference leaders of the
worlds discussed about
sustainable development
and they adopted 21
points policy which is
called ‘Agenda 21’.

7. Resource Planning and Its Steps
Resource planning is method to use the
resources in optimum way so that maximum
benefit should reach to maximum people.
Resource planning also means avoiding
wastage, misuse and overuse of resources.

8. Three steps for resource planning.
Identification and inventory of resources by
surveying and mapping
Evolving a planning structure to use the
resources with appropriate technology
Matching resource development plan with
national development plan

9. Need and Methods of Conservation of
Resources
“There is enough for everybody’s need and
not for anybody’s greed”
-Mahatma Gandhi

10. Why resources should conserve?
Resources are not found everywhere. They are
unevenly distributed.
Resources are limited. Many of the resources are
non-renewable.
Resources should be conserved for reducing all
kinds of pollution.
Resources are also conserved for ‘sustainable
development’.
Conservation is needed to protect natural
heritage.

11. Methods for Resource Conservation
Wastage, misuse and overuse of resources
should be avoided.
Renewable resources should be used more
e.g. solar energy, wind energy etc.
Older technology should be replaced with
newer, modern and efficient technology.

12. Awareness should be created among the
people.
Govt. should pass strict laws for establishment
and location of industries.
 Used items should be recycled using new
technology.
