This is a pioneering and unique initiative of the government of Tamil Nadu with objectives to integrate bio-diversity conservation and sustainable utilization of resources in the Gulf of Mannar Biosphere Reserve area through meaningful co-ordination and support from various stake holders and to secure local community support for conservation through awareness, capacity building and providing alternative livelihoods. The Gulf of Mannar is no doubt a biologically rich area. Today the threats to its richness are increasing at faster rates which need to be controlled through an integrated management approach with support from all the stakeholders. In order to understand the richness and the problem profile of the area the Trust has bought out a detailed bibliography on scientific information on the Gulf of Mannar through active involvement of the centre for marine and coastal studies, Madurai Kamaraj University recently. The research work done by various individuals and institutions in the area has now been well documented. Based on the outcome of this documentation the Trust is now organizing a National Research Monitoring and Moderation workshop on 15th - 16th Dec. ‘06 at Madurai where distinguished scientists, experts other stakeholders will gather to deliberate on various issues on Research and Monitoring in the Gulf of Mannar region and jointly develop programmes and activities for field action by next year. The Trust has also compiled some research papers as a publication for use in this workshop wherein the future perspective of research, monitoring and management of this area are covered. The Trust Director and his team deserve appreciation for this effort. I wish the workshop all success. (Vishwanath Shegaonkar) i C.K.

Coastal and marine ecosystem are extremely diverse and complex as well as highly sensitive to disturbances and threats which are continuously on increase due to growing populations and their need clubbed with fast growing economies. The Gulf of Mannar Region in South east coast of Tamil Nadu is equally under threat as many other parts of the Country. A new initiative for integrated conservation of this area with full involvement of local communities is being made in a collaborative project of GEF, UNDP, GoI and GoTN. In order to minimize and control the threats it is necessary to understand about the richness of the resources and the profiles of the threats so that the management interventions can be developed and implemented for enhanced conservation and sustainable use of the resources. As a first step Gulf of Mannar Biosphere Reserve Trust has bought out a detailed bibliography on the scientific information on the Gulf of Mannar which is of much use to the scientists, researchers, managers and the other agencies involved in the Gulf of Mannar area. I am glad to learn that the Trust is organizing a two day workshop at Madurai in order to deliberate on various issues related to priority areas and options for research and monitoring activities in the area and releasing a publication on compilation of some research papers focusing on the future perspective of biological, ecological and environmental research and monitoring activities in this area. I hope that scientists, experts and other stake holders will utilize this opportunity and provide inputs towards developing workable, short term and long term programmes on research and monitoring aspects in the Gulf of Mannar Region. I wish to extend my greeting to all the participants and wish the workshop all success. (C.K.

Sincere and committed action on part of all the stakeholders and local communities is necessary to control and curb the threats and to use the resources judiciously so that the glamour, beauty and richness of the area is maintained on a sustainable basis. Gulf of Mannar Biosphere Reserve Trust has made sincere beginning under the GEF-UNDP Project to secure coordination, cooperation the support of all stake holders towards achieving conservation and sustainable utilization
