Aquatic Pollution and Coastal Management

Unit 14 : Coastal zone management and information system

14.5.Management Methods and Information System
A good understanding between the changeable landform futures and related land use/land cover (i.e., soil-vegetation-water interrelationship) is very essential for maintaining the natural ecosystem of the coastal zone, as well as marine environments, especially when the natural set up is being largely threatened by various anthropogenic activities starting from

• Checking the upland fluvial discharge
• reclamation of coastal low lands wet lands
• destruction of mangrove forest, coral reefs etc and
• discharge of pollutants.

Such change detection studies require continuous monitoring of the coastal futures and the land cover/land use patterns as well as of ocean surface. In this respect utilization of the aero-space data not only provide a wealth of subject specific information to the users community in a coast effective manner (considering both time and economic aspects) but also quality is much more improved than the traditional means of approaches. It is now being an established fact that the remote sensing application is very suitable one time inventories and service as well as for continuous monitoring in time and space of natural resources and one that is able to provide accurate and regular updated information essential to successful GIS-based modeling for management and planning is user orientation.
