CHAPTER 1 • Principles and Benefits of Integrated Coastal Zone Management (ICZM)

3. Based on (a) the relationships defined in N° 1; (b) the demographic conditions specified in N° 2; (c) the sequence of meteorologiclhydrologic events selected in the scenario; and (d) changes, if any, in factor prices and technology specified in the scenario, estimate the extent of various problems and the damages associated therewith for the "trend" management strategy, and the associated benefits and costs
(where costs represent the incremental costs in addition to existing costs at time To).
This yields the net benefits for the "without ICZM".
4. Define an ICZM strategy, which involves - as noted above - some combination of
physical (structural) measures and non-structural (charges, land use regulations)
measures, and the capital, OMR, and administrative costs associated therewith.
5. For the same scenario as selected in N° 2, estimate the benefits from applying the
ICZM strategy defined in N° 4, remembering that explicit consideration must be
given to the extent to which the coastal occupants actually behave as "assumed" in
response to the various incentives imposed.
6. Calculate the net benefits associated with the ICZM strategy defined in N° 4.
7. Compare the net benefits estimated in N° 6 with the net benefits estimated in N° 3.
The result represents the net benefits from ICZM.
The method for estimating benefits from ICZM can be illustrated by applying the
method to a prototype or actual coastal system. The prototype system has characteristics analogous to real coastal systems. Data on costs, various relationships involved
in the performance of natural systems, values of unit discharges, and so on, are based
on data from the "real world". The prototype contains a variety of typical uses of coastal
resources and the competitions between and among those uses. It may be useful in order
to test a range of general relationships and/or in cases where the actual coastal systems under review are particularly complicated or for which data is severely limited.

Conclusions
Coastal zones are under increasing pressure from the scale of the multiple resource
demands that are impinging on them. Multiple usage of the goods and services provided by coastal systems reflects a variety of stakeholder interests and perceptions. A
number of these uses and interests and perceptions conflict with each other and are
themselves changing over time. The management process deployed in order to maintain an acceptable mix of outputs from the coastal zone into the future must therefore
be both a dynamic and an adaptable process. Past and current market and government
intervention failures will need to be corrected if pollution and resources loss trends
are not be exacerbated. An integrated approach to coastal zone planning and management (ICZM) is necessary in order to produce (effectively and efficiently), and/or enhance the mix of goods and services that society wants, and to ensure an equitable
distribution of the benefits of ICZM.
Integration in ICZM includes its integration across broad policy objectives and plans,
with different sectoral plans and management, with different levels of government and
with the public and private sectors. ICZM itself must encompass all the elements of
management from planning and design through financing and implementation. It also
requires an interdisciplinary analytical and operational approach. Because of the dy-
