The trade off between ecology and economy has become an important issue in
the evaluation of planned interventions in the Dutch coast. The complexity
of the issue is reflected by the long and difficult national debates that t
hese interventions cause. Both public policy makers and private stakeholder
s seem to be in need of instruments to support the lengthy decision making
process. The aim of this article is to discuss what type of instrument is n
eeded to facilitate the decision making process by addressing the following
research questions: (1) Can the way in which stakeholders are dealing with
nature in practice, be explained by their basic views on nature? (2) Can t
rends in public policies be explained by these views on nature? The answers
to these two questions are obtained by conducting a survey among public an
d private parties involved in a case study of a planned intervention and a
historical review of policies in the field of nature conservation and coast
al zone management. The findings are translated into a description of neces
sary decision support instruments. In order to explain how stakeholders wis
h to deal with nature in land use plans, a framework of attitudes towards n
ature, basic views of Conservation, Development and Coevolution, views on n
ature in the region and design strategies is used. Both the case study and
the historical review reveal that the views of Conservation, Development an
d Coevolution coexist within Dutch society, but a strong tendency towards t
he Coevolution view can be discerned. According to the Coevolution view, bo
th society and nature are allowed to change and to inflict change upon each
other as long as sustainability prospects are enhanced both for society an
d nature. Though the Coevolution View is very attractive intellectually, it
is still in its infancy and the envisaged policies remain quite vulnerable
due to a lack of adequate instruments to internalize the value of nature i
n economic transactions. Though theoretical concepts, such as socio-economi
c valuation, are available to facilitate the trade off between ecology and
economy, these still lack practical applicability. Even if appropriate deci
sion supportive instruments are developed, society is likely to bounce back
to a Conservation approach in its actual decision making, as long as there
are no institutional and legal arrangements to ensure their use. (C) 1999
