Hence, in the new development paradigm the
environmental dimension is an integral part. The
shifts in emphasis are evident when one compares
project documents of the 70s with those of the
present. In the 70s donor agencies barely mentioned
environment. In contrast, at present, agencies such
as the World Bank, Asian Development Bank and others
insist on a systematic appraisal of the
environmental aspects and Environmental Impact
Assessment (EIA) has become important. The task of
introducing explicit environmental considerations
into development planning is emerging slowly.
However, it must be conceded, that differences of
opinion continue regarding their role. In fact, one
can identify three strands of thought in the debate
on links between population, environment and
development:
1. Eco-Radical viewpoint, which holds that
developmental activities should be subordinate and
environmental issues, ought to be the primary
concern. The protest against mega projects such as
the Narmada is an example.
2.Another viewpoint holds that developmental concerns
are of paramount importance. It stresses the
significance of scientific and technological advances
and points to how Malthusian predictions were rendered
wrong due to man devising more effective techniques for
coping with situations.
3.
The third viewpoint emphasizes the need for blending of
economic objectives with environmental imperatives in
order to focus on sustainable development, with the
involvement of all the stakeholders in policy
formulation.
The
concept of ecological sustainability has to take into
account the three basic functions of environment for
man, viz., provision of (a) natural resources such as
food, raw materials etc.,
(b)
publicly shared resources such as atmosphere, ground
water, biodiversity etc., (c) receptacles for solid and
liquid wastes.
How
is the concept to be applied? The conventional method
was through the determination of the carrying capacity
of an area, i.e., the maximum population that a given
habitat can support indefinitely. However, as Rees and
Wackernagel (1994) remark, ‘ in a economy globally
integrated through trade, regions can no longer be
viewed as independent units’. Hence they argue, “ that
rather than asking how many people a given region can
support, the relevant question becomes: How much
land/water, wherever it may be located, is required to
produce the resource flows (consumption) currently
enjoyed by the region’s population?” The estimate of
this quantity represents the “ecological footprint” and
provides a physical measure of the demand on natural
capital. The concept of ecological footprint can be
applied at different scales of analysis, i.e., a city, a
region, a country or the earth. For example, an urban
area can survive only if there are reliable supplies of
food, water and raw materials. Equally important is a
surplus waste absorption for the tremendous wastes-
solid, liquid and gaseous- generated in a city. Thus,
the ecological footprint of a large city is much larger
than the area it physically occupies. The same is true
of densely populated areas. Sophisticated techniques of
analysis have been evolved in the field of environmental
economics to determine the ecological footprint of any
given area.
The
concept of the ecological footprint focuses attention on
the interrelationship between man and environment. It is
pertinent to conclude with a story from our scriptures.
When Vamana went to King Bali’s court he was asked what
boon he wanted. Vamana requested for an area equivalent
to three of his footprints. When King Bali agreed to his
request, Vamana grew in size. He occupied the entire
land surface with one footprint and the whole ocean
surface with the second. Since there was no space for
the third, the king asked Vamana to place his foot on
his head. With this move, the king was pushed into
oblivion (Pathala loka). This illustrates the danger
that mankind faces if cognizance is not taken of
ecological issues and efforts made to reduce the extent
and magnitude of ecological footprints.
