Discuss the environmental dimensions of a project. and explain the different stresses on environment.
Ans. The effects of actions that are not accounted
for in the normal market transactions need to be considered explicitly in the
decision making process on projects. These effects are to be identified,
assessed, and evaluated against the economic advantages arising out of a given
action. In this context, the environmental impact appraisals are considered the
first step in the process because they give an
opportunity to man to consider the effects of
his actions on the environment. Economic development is the result of the
interaction between natural resources and technology supported by and designed
for people. People are the centre for development. Therefore, it is rightly
said that all human activity, be it economic, social or anything else is
essentially directed at satisfying “needs” and “wants” of man through
“altering” and “using” environmental resources.
Types and environmental dimensions of a
project
Broadly, there are two types of projects. The
first one refers to those projects that produce physical goods like cement,
steel, paper, chemicals etc. These projects, in fact, convert the natural
resources into saleable and exchangeable products. In fact, these projects
inflict a large number of physical changes and disruptions on environment and,
hence, disturb the environmental and ecological balance.Environmentalists are
mostly concerned with such type of projects. The second type refers to those
that produce/render various kinds of services such as health, education,
transport, energy, defense, law etc. Such projects also cover actions like land
reforms, agricultural extension, services, sales promotion campaigns, etc.
Projects of these types are non-physical in nature and they do not directly cause
any physical changes in the environment. However, they bring about significant
changes of far-reaching consequences on values, attitudes, lifestyles, social
relations, and so on. The net effect of such projects is the creation of new wants
and needs in society. They ultimately promote consumerism in the society and
thereby increase the number of manufacturing projects. Thus, both are
interrelated.Each project has two dimensions:
(a) the intended objectives – they are also called
stated goals/benefits; and (b) the unintended consequences. They are also called
externalities or social costs which are unplanned, unwanted, and unanticipated.
Environmental management or planning is the study of the unintended
consequences of a project. Its purpose is to identify, examine, assess,and
evaluate the likely and probable impacts of a proposed project on environment
and, thereby, to work out the remedial action plans to minimize the
incidence of adverse impacts. It is not
anti-development nor is it against the projects. Its goal is development
without damage or least damage.
Stresses on environment
Environmentalists have identified four types
of different stresses or pressures that are
being continuously inflicted on environment. They are:
i) Atrophic Stress Refers to the
release of various kinds of wastes into the river and other water bodies and
their consequent drying.
ii) Exploitative Stress Refers to the
exploitation of natural resources endowment for production and consumption
purposes through agriculture, industry, extraction, fishing etc. It is
important to note that the rate of exploitation has a relevance to the nature’s
capacity to reproduce.
iii) Disruptive Stress Refers to the
physical alterations in nature resulting from such activities like forest
clearance, highways, railways, factory buildings and so on. These physical
changes disturb the environmental and ecological balance.
iv) Chemical and Industrial Stress results
mainly from the developments in “science and technology” and their applied
fields like industry, warfare and agriculture. This comprises mainly the
pollutants and effluents of all types, radiation etc. Strategies to face these
threats to natural environment through pollution, destruction and over-use can
be: (a) preventive or (b) regulatory. It is in this context that the
environmental appraisal of projects is gaining significance with a hope of
achieving sustainable development in harmony with environment.
