This paper aims at specifying the contribution of OR to environmental
planning. To this purpose a framework for classifying relevant literat
ure is proposed, according to which the literature has been reviewed a
nd discussed with respect to both thematic and methodological aspects.
It is shown that during the last few years, OR has extended its scope
to include notably environmental applications. Several OR methods and
tools are employed either to identify the type and intensity of envir
onmental problems, or to assist environmental planners to effectively
cope with these problems. It is illustrated that OR's relationship wit
h environmental planning is dynamic and interactive in the sense that
from the complexity of the issues examined stems the need to develop a
nd/or adapt specific methodological tools and thus contributes to the
development of both scientific fields. (C) 1997 Elsevier Science B.V.
