GIS and Marine Resource Management

We have discussed what Geographic Information System (GIS) are and how they can used in Land Resource Management, in transportation and Natural Resource Management. Today we will be discussing about GIS application in Marine Ecosystem Management.

Application of Geoinformatics in marine resources:

The increase in population and fast dwindling land resources lead to tapping and exploitation of ocean resources. Exploitation of ocean resources may cause ecological imbalance. In addition to this, oceans play an important role in climatic changes, influencing monsoon that decides the economic development of many economies. Remote sensing technology is extremely useful to study and manage the ocean resources. RS and GIS applications area has extensively used this technology for the following purposes:

  • Ocean colour, wind and temperature: methodology development
  • Ship tracking and navigation studies
  • Coastal environmental studies
  • Development of irrigated fisheries forecast model
  • Surface sediment dynamics

GIS provides the resource managers with a means to integrate scientific data with prevailing cultural values and traditions. GIS allows interpretation of many terrestrial and marine datasets, fisheries catch data, seabird standings, marine political boundaries, as well land cover classification from watersheds, roads, satellite imagery, streams and political boundaries. The marine GIS have all the aspects for making it a fertile domain area for research. Further remotely sensed SST, wind and other parameters can be used to model to predict fish abundance, their habitat and related aspects.

Marine Fisheries Management and planning:

  • The objective is to encourage GIS tools to foster the sustainable use of natural resources.
  • It aims at aquatic resource managers, decision managers and fisheries biologists in developing countries that have little or no knowledge about GIS.
  • Oil and chemical spills can have widespread impacts and long term consequences to wildlife, coastal and marine habitats and human health. A GIS can assist oil and chemical pollution.
  • A GIS can provide uniform spill response.
