2. Ecological restoration and planning for Alang (1996-1997) – Sponsored by Gujarat Maritime Board

The study was undertaken to evolve an alternative development plan that is ecologically sound and devise methods for proper regulation of activities of the Alang-Sosiya shipbreaking yard. A comprehensive investigation of ecological features of the coastal area, littoral zone, and offshore region was carried out with the help of specific task forces. Some of the more critical issues such as heavy metal pollution, oil and hydrocarbon, and the occurrence of pathogens were also undertaken. After understanding the local ecosystem dynamics, a practical strategy for the prevention of pollution, the upgradation of landscape, conservation of biological diversity, and betterment of the human population concerned with this industry were recommended. The study also identified areas for fresh intervention for ecologically sustainable development of the region.

6. Socio-Economic Study of the Fishing Communities around Pipeline Marine Project location at Bhogat (2011) – Sponsored by Crain Energy Pty Ltd

The present study involved the development of a socio-economic profile of the fisherman communities in the area and a social-baseline survey of the fishing villages within a 5 Km radius of Bhogat village. Based on the results the short-term and long-term community development interventions that will be relevant to the community had to be designed. The study highlighted the status of fishermen in two fishing villages. The fishing villages lacked the basic amenities and sustained fishing. The fish catch patterns at Navadra show the lowest production in 1998- 99 and peak up in the year 2000-01 and then decline gradually. The reasons for the decline could be due to natural phenomena like poor primary productivity in coastal regions and anthropogenic factors like over-exploitation.

7. Marine Environmental Monitoring Plan during Dredging Operations at Bhogat (2011) – Sponsored by Leighton, UK

The present study was done close to dredging activity to see the impact of dredging on the surroundings and suggest remedial measures.

Thirteen sampling stations were selected for this study. The scrutiny of the results from the periodical observations of the present study revealed that the coastal waters of Porbandar and Veraval are affected due to the impact of industrial and fishing activities. In contrast, the coast of Mahuva, Gopnath, and Hathab are distressed by the river-borne high concentration of total suspended solids. Interestingly, the corals were observed for the first time at Dwarka, Veraval, Diu, and Mahuva intertidal regions.
