Ecosystem management
Ecosystem management
is a very important in the world. New let us move from the general consed ration of control theory to specific examples to show that peoples attitudes
toward the environment are really changing. Two examples from California should
suffice to illustrate trends. First, the matter of deciding where future atomic
power plants should be placed. In terms of environmental costs the least expensive
site would be along the coast where large volumes of seawater are available for
cooling purposes. Inland location with freshwater cooling ponds would be the
next post , while installation of wet cooling towers would increase costs. The most
expensive option would be dry cooling towers, which, however, would spare water
for other uses. Ten ago decisions would have been made only on economic and
engineering fronds with the likelihood that many power plants would be located
along the coast. Now, with the public and environmentalists deeply involved in
the discussions and decision making, it seems likely that very few power plants
will be built on the coast because the natural scenic and recreational values
are being given greater value, as evidenced by recent state wide ote in favor
of the coastal protection ‘’proposition 20’’. The combination of setting aside large areas as natural reserves and the increasing cost of energy can act
as powerful negative feedback that could be a beneficial factor in slowing
urban type growth to a manageable rate.
A remarkable little book entitled the California tomorrow
plan, edited by Heller and first published in 1971, is evidence of a
reorientation of values and priorities on an even larger scale. This report,
prepared by a citizens’ group, assisted by various professional groups, proposes that a state commission be set up by the legislature to design a land
– use plan for public debate and eventual adotion. Such a plan would regulate
the kind and intensity of development and would identify and preserve the life
support function of the natural environment as well as preserve the quality of
life in the cities. A unique feature of the plan is the proposed setting aside
of large reserve where decisions on use would be postponed for sometime in the
future, thus providing flexibility for future contingencies. Widespread resistance
to planning at the present time is based on the very real fear of loss of
individual freedoms as a result of increasingly dictatorial and bureaucratic control.
As shown in which is reproduced from Heller book, this need not be the case. Regional
control of environmental matters would seem to be a good compromise between
central control which would not be responsive to local needs, and purely local
control (as is now the case) which is inadequate to cope with the scale of the
problems. In other words, what seems to be needed is expanded control of vital environmental matters in order to reduce central control of personal matters. Freedoms
is not the absence of constraints, but is measured in terms of a variety of
options available to the individual. Reservation of a wide variety of
environments in functional balance provides the basis for choices. This, then, must be the aim of ‘’ecosystem
management’’ a new venture foe mankind. There has been a great surge of inters
in research on comprehensive planning accompanied by growth in student enrollment
in university schools of environmental design, environmental engineering,
natural resources, urban planning, schools and departments of social and
political and political science, and the like. Foundations, ‘’think tanks,’’ and
consultant groups are all responding to the need. Perhaps soon schools,
institutes, and centers of ecosystems man engagement ill be formed to coordinate
all of these special interest applied groups.
