Fourth National Symposium
On Marine Environment
20th October 2018 at Lotus Hall - BMICH

2. “The ocean is the life
support system for the
planet earth”

3. Significance of the Study
40% of the world oceans
are heavily affected by
human activities, including
Pollution,
depleted fisheries and loss
of coastal habitats

4. This paper
discusses,
What is Blue Economy
Threats to Blue Economy
Ocean Based and Ocean Related
Activities
New industries in Blue Economy
Coastal Management and the way
forward.

5. “The blue economy refers to a sustainable ocean based
economic model that is largely dependent on coastal
and marine ecosystem and resources”

6. Ocean-based
Activities undertaken in the ocean such as
1. Fisheries and marine culture,
2. Offshore oil and gas,
3. Mining,
4. Ocean energy,
5. Desalination,
6. Shipping/marine transportation,
7. Marine tourism and construction
Marineculture Projects

7. Ocean-related
Which uses products from the ocean
1. Seafood processing,
2. Marine biotechnology,
3. Chemicals,
4. Salt and other products
Services for ocean and ocean based activities
1. Shipbuilding and repair,
2. Ports,
3. Tourist resorts,
4. Communication,
5. Marine insurance and law, and
6. Marine technical services

8. Are we heading to
a sustainable
BLUE ECONOMY
???????

9. Threats to Blue Economy
1. Offshore oil and gas
Exploration.
2. Commercial and
Recreational Fishing.
3. Marineculture Projects.
4. Shipping.
5. Coastal Tourism.
6. Telecommunications.
7. Waste Disposal; Plastics,
Chemicals, Oil

10. Human-made Pollution
Oil Spills ; Dumping of Toxic Waste; Dumping of Plastics

11. Dumping of Untreated Sewer

12. Huge Dead Zone in
Bay of Bengal
60,000 Sq Kms
1. Little or no oxygen
2. Do not Support
Microbial Process
3. Remove vast amount of
Nitrogen from Sea

13. Noise Pollution
Fish will have to wear
ear protection

14. Illegal
Unreported
Unregulated
Fishing
1. Fishing without License
2. Fishing over Quota
3. Fishing – not reported

15. Destructive Fishing
Methods
1. Chemicals or explosive
devices,
2. Bottom trawling,
3. Unauthorized types of nets
to catch the fish

16. There is no doubt
that the Blue
Economy is the way
forward for the
humankind in the
next decades to
come

17. Blue Ocean Economy: Way Forward
1. Use of Marine Living Resources
2. Building Resilience of Marine Resources to the impact of Climate
Change
3. Marine Bio-diversity
4. Developing Technologies to set up Enterprises using Blue Eco System
wealth
5. Public Private Partnership

18. Pollution Prevention
Now: Ships depend
heavily on oil as a
fuel
Future: Solar
Powered Ships &
Wind Power

19. New Industries in Blue
Economy
1. Renewable Energy.
2. Seabed Mining.
3. Remediation/restoration.
4. Blue Biotechnology.
5. Blue Technology.

20. Ocean Resource management in the Coming
Decade
Prevention and reducing all kinds of marine pollution
Sustainably manage marine and coastal ecosystems
Minimize and address the impact of ocean acidification
Effectively regulate harvesting and overfishing
Ban selling of IUU fishing
Increases scientific knowledge and develop research capacity

21. Thank you
We need man power;
Scientists, Researchers,
and Entrepreneurs with
Blue Economic mind-set
