Integrated coastal zone management in South America: A look at three contrasting systems
Author
Abstract
The management of coastal systems where overlapping economic interests compete for the same
resources make the use of integrated approaches indispensable. The Integrated Coastal Zone Management
(ICZM) focuses mainly on three major goals: (1) overcoming the conflicts associated with the
sectorial management, (2) preserving the productivity and biological diversity of coastal systems, and (3)
promoting and equitable and sustainable allocation of coastal resources. The DPSIR (Drivers-Pressures-
State-Impact-Responses) framework is a common tool that allows the description of environmental
problems by defining the relationships between anthropogenic activities and the environment. In this
context, the use of numerical models as integrative tools in ICZM has grown significantly over the years.
This work focused on three estuarine systems in South America: Santos estuary (Brazil, 24 S) and
Bahía Blanca estuary (Argentina, 39 S) in the Atlantic coast and Aysén fjord (Chile, 45 S) in the Pacific
coast. These estuaries differ significantly in their physical, chemical and biological conditions, as well as
on their socio-economic settings and human-related problems. Numerical models have been used to
study the relation between the pressures derived from human activities and their impact on the state of
each system.
The results presents a contribute to increase the scientific knowledge needed to support the implementation
of local legislations and policies, to assess different scenarios of coastal activities and sources
use, to support management decisions and, ultimately, to promote sustainable of coastal resources.
