Individual actions :
-
impact study prior to implementation of any new development ;
-
impact assessment of various discharges upon the quality of water which
could lead to ecosystems modification, even though the marine environment
can "absorb" waste far better than its land counterpart through dilution,
dispersion and degradation ;
-
assessment of impacts of new constructions near the edge of the sea on the
shoreline's evolution ;
-
managing pollution ; limitation of discharges, purification stations ....
-
managing coastal erosion : provision of defense structures.
-
Finally, the development of protected areas is necessary. One must define
"control zones" and monitor their integrity, in order to safeguard a part of
the natural patrimony, so that it can be conserved for future generations,
and also to preserve the equilibria that are necessary, e.g. in fish spawning
grounds.
5 Conclusion
The coastal zone is subject to such pressures, not counting anthropication, as
erosion, sea-level rise, hazards, but thus also to exploitation and increased
migration. While any management scheme must provide for relief of pollution,
natural and otherwise, it must face the reality of sea-level rise and of retreat of
the shoreline.
Subsidence and anthropogenic activities such as oil-, gas-, sand extraction, and
barrage construction, contribute to beach retreat, further aggravated by offshore
airport-runway or artificial islands construction, coral reef exploitation, mining
and tourism depredations.
Multiple-use of coastal zones has been practiced in many geographical areas, and
usually flourished harmoniously. But contemporary competitiveness differs
greatly from ancestral arrangements. Management systems often fail to harness
the resource potential offered by natural systems.
