Objectives of Sustainable Development
It is obvious that the earth and human civilization can be preserved only with
sustainable development. Man is the central figure of development works. Thus, he
should conduct any development activities being environment-friendly. Some of the
principles of sustainable development activities are mentioned below:

a. Conservation of Ecosystem
The principle of sustainable development is to create balance between biotic

and abiotic aspect of environment. It helps to protect earth. In order to conserve
it, the aquatic and terrestrial ecosystem should be protected.

b. Conservation of Biodiversity
It is essential to protect the plants and animals of the earth. If these are affected

while carrying development works, it brings adverse effect on environment.
Thus, sustainable development focuses for the conservation of biodiversity.
For this, national and international programmes are to be conducted.

c. Control of Rapid Population Growth
People survive by consuming the means and resources on the earth. But

rapid population growth increases the consumption of resources rapidly. The
resources of this earth cannot be expanded to the need of people. Therefore,
sustainable development focuses to control population to minimize the
consumption of resources so as to conserve them.

Blooming Science & Environment Book 8 323

d. Development of Human Resource

Man has an important role in utilization and conservation of environment.
For the sustainable use of resources, knowledge and skill of people should be
developed. The development of human resources helps to apply the principles
of sustainable development.

e. Increase in People’s Participation

Local people are the consumers and conservers of resources. In the absence
of people’s participation, natural resources can’t be conserved. In this regard,
sustainable development emphasises to increase people’s participation.

f. Conservation of Cultural Heritage

Man-made social tradition, customs, religious place and culture are focused
aspect of sustainable development. These important gifts of society are to be
preserved reforming the bad customs. Conservation of these aspects supports
the sustainable development.

g. Limit of Carrying Capacity

Human being should conduct the development works considering the
carrying capacity of the earth. The earth has limited carrying capacity. Over
use of resources and unlimited development activities bring adverse effect
on environment. Therefore, man should conduct development activities in
accordance with the carrying capacity of the earth.

Implementation of Sustainable Development

The principle of sustainable development

should be integrated in the various fields of

development work. Short-term utilization of

natural resources makes the existence of living

creatures including man difficult. It also creates

inequality in the economic and social aspects

of the society. Development and environment

are interrelated to each other. Therefore, we Fig: Motor boat
should not forget to protect environment while

carrying development works. It is mentioned in the World Development Report

that “Development without adequate environmental conservation is weak, without

development the means for necessary investment will lack and the environmental

conservation will be unsuccessful.” By realizing this fact, sustainable development

is to be applied in the various fields.

Agriculture, infrastructure, industry, forest, transport, tourism are the major

324 Blooming Science & Environment Book 8

development areas. The principle of sustainable development is to be applied while
developing these fields. Except these, bio-engineering, eco-tourism, nuclear energy
production are the fields to apply sustainable development.

Eco-tourism is one of the important areas of application of sustainable development.
The world Tourism Organization declared 2002 A.D. the International Year of Eco-
tourism, highlighting the growing importance of sustainable development.

The following concepts should be integrated for conducting development works in
the light of sustainable development:

1. Development activities should integrate conservation programmes.

2. Emphasis should be given for the social development.

3. The programmes of conserving animals and plants should be adjusted in
accordance with development works.

4. Natural resources should be used rationally. Perpetual resources should be used
maximum whereas there should be the minimum use of non-renewable resources.

5. Development works should be limited within the earth’s carrying capacity.

6. The construction and use of destructive objects, dangerous to human society
and environment should be made illegal and prohibited at global level.

Global efforts for Sustainable Development and its Importance

UN GeneralAssembly formed aWorld Commission on Environment and Development
under the chairmanship of Norwegian Prime minister G.H. Brundtland to suggest
the world on environment and development in 1983. This commission is known as
Brundtland commission. The commission published a report entitled “Our Common
Future” in 1987. The report included the concept of sustainable development.
According to this report, “Sustainable development is a process in which exploitation
of natural resources is done to fulfill the needs of present generation without
compromising the ability of future generations to meet their needs.” The World
conservation strategy was formulated in 1980. On the basis of this strategy, policy
and practical works about caring for the earth can be designed and implemented. To
execute this strategy, the strategy “Caring for earth- for sustainable Development”
is formulated. On the basis of this strategy, different countries have formulated their
national policy of caring for the earth and sustainable development.

The earth has limited carrying capacity. So, development works must not be carried
out beyond the carrying capacity of the earth. Excessive exploitation of natural
resources deteriorate the environment. Unplanned development works destroy the
original status of the nature. Consequently, environment gets imbalanced. It adversely
affects the living beings. It hampers the progress of human too.

Human beings should think that they cannot get victory over nature. So, they should

Blooming Science & Environment Book 8 325

respect the nature and use the existing resources wisely keeping in mind that they
should save it for future generations.
Sustainable development aims at utilizing the natural resources to improve the
socio-economic status of present generation without deteriorating their quantity and
quality. In other word, sustainable developments is nature-friendly development in
which conservation activities are integrated with development work.

Importance of Sustainable Development
Sustainable development should be practiced for the welfare of current generation
as well as to help maintain the same standard of future generations. The goal of
development cannot be achieved when adverse effects are produced by the development
works. The importance of sustainable development is described below.

a) Appropriate Use of Resources:
Sustainable development encourages people to use the means and resources as

minimum as possible and less wastefully. Maximum benefit should be generated
by minimum use of the resources. This helps to conserve and promote the
environment.

b) Sense of Responsibility:
Sustainable development awakens the people about the wise use of natural

resources. It brings about changes in people’s knowledge, attitude and skill.
People realize that resources are invaluable gift of nature and their common
property. So, it is their common duty to conserve the natural resources.

c) Development of Basic Infrastructures
Sustainable development stresses on the progress of health, education,

agriculture, tourism etc. for the welfare of human beings. It aims at sustainable
development of the society through continuous availability of development
benefits. At the same time, it focuses to conduct the environmental conservation
programmes in an integrated way.

d) Development Based on Public Participation:
Priority is given to public participation while conducting development works

under sustainable development. It creates interest in local people about
development and conservation of resources. It helps to develop skill and
effiency of the people.

326 Blooming Science & Environment Book 8

e) Determination of Limit of Development:

Sustainable development aware the people about the bearing capacity of the
earth. Limited but effective development works should be conducted for
sustainable benefit. If development works are carried out randomly without
limit, it will be just waste of resources. Sustainable development suggests the
policy makers about the concept of limitation of development.

f) Long Term Vision:

Sustainable development has a goal of long term socio-economic development.
Without conservation of resources, it is not possible. It emphasizes on the
conservation of natural means and resources for the future generations.
Development activities are conducted by considering the future.

Need and Importance of Nature Friendly Concept

Nature has its own rule. It has self-regulatory mechanism to maintain the harmonious
relation between biotic and abiotic components of the environment. Until it is untouched
by human encroachment, there is natural balance. But when human activities grow
in nature, its natural system gets imbalanced. When natural resources are exploited
beyond limit and development activities are conducted without considering earth’s
carrying capacity, natural balance is lost. The activities of human which protects our
natural assets and reduces the impact of development on natural resources is termed
as natural friendly concept. Nature friendly development is also known as green or
low impact development. Earth’s original structures are not destroyed in this type of
development. Efforts are made to maintain the natural condition of water sources,
wetlands, land etc. For the sustainable development, human activities should be
nature-friendly. Nature should be respected and its originality must not be changed,
which helps to maintain the environmental balance and conserve ecosystem and bio-
diversity.

The importance of nature friendly development is given below.
1. Preserves natural areas and minimizes land disturbances.
2. Protects natural systems like wetlands, wildlife, vegetation etc.
3. Minimizes soil compaction.
4. Improves water quality and protects drinking water supply.
5. Protects and creates healthy habitat for fish and wildlife.
6. Conserves resources and reduces energy use.
7. Keeps the earth green and beautiful.
