Blue Economy in Bangladesh: Next Resources Exist

Blue economy is the basis of a sustainable development of the ocean-based country like Bangladesh. Sustainable development is the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Blue economy is the use of sea and its resources for sustainable economic development and the concept is new in Bangladesh and South Asia. Long-term prosperity can be achieved using sea area by a country befitting the wellbeing of all citizens and the mankind conserving the environment. This review focused on the importance of blue economy in Bangladesh along with some meaningful recommendations for successful execution of Blue economy concept.


Ocean's Contribution
Ocean cover most of the planet hydrosphere [4]. Oceans are covering approximately 71% of Earth's surface and 90% of the Earth's biosphere [5]. The ocean contains 97% of Earth's water, but less than 5% of the World Ocean has been explored [5]. Ocean is the major constituent of Earth's hydrosphere as it is integral to life, forms part of the carbon cycle, and influences climate and weather patterns. Oceans are suitable habitat of 230,000 known species and many unknown species (in total possibly over two million) [6]. Primitive life first evolved in the oceans. Ocean act as a natural or artificial reservoir that amasses and stores some carbon-containing chemical [7]. Oceans absorb carbon dioxide (CO 2 ) [8], release oxygen (O 2 ) [9], recycle nutrients and regulate global climate and temperature [10]. Moreover, Oceans provide food and livelihoods of the global population and are the vital way of transport for 80% of global trade [3]. Tourism industries are established along the marine and coastal environment. The seabed currently provides 32% of the global supply of hydrocarbons and renewable "blue energy" production from wind, wave, tidal, thermal and biomass sources. Ultimately it offers 31 million direct full-time jobs in 2010, around 1% of the global work force and about 1.

Established and Emerging Sector Based on Ocean
The scenery of traditional maritime industries will be faced substantial change in the upcoming decades due to global economic growth and increasing demand. For example, in the shipping sector, container traffic looks set to continue to grow very fast, with volumes likely to triple by 2035 [12]. Although the main driver of overall production will be aquaculture, but fisheries production worldwide is projected to expand by around a fifth over the next ten years [13]. The established and emerging ocean-based industries are include: capture fisheries, marine aquaculture, seafood processing, deepand ultra-deep water oil and gas, shipping offshore wind energy, ports ocean renewable energy, shipbuilding and repair, marine and seabed mining, offshore oil and gas (shallow water), maritime safety and surveillance, marine manufacturing and construction marine biotechnology, maritime and coastal tourism, high-tech marine products and services, marine business services and education and dredging [11].

Scope of Blue Economy
Blue Economy deliver chances for sustainable, clean, reasonable blue growth in both traditional and emerging sectors; fishing, marine biotechnology, minerals, marine, renewable energy, marine manufacturing, shipping, port & maritime logistics, marine tourism & leisure, marine construction, marine commerce, marine ICT, education and research (Sources: Compiled from Morrissey (2010), EIU (2015a), Govt. of Ireland (2012) and Marine Institute).

Blue Economy for Bangladesh
Ideas, principles and norms of Blue Economy can play significant role in the context of poverty eradication, food and nutrition security, mitigation and adaptation of climate change and generation of sustainable and inclusive livelihoods [14]. To obtain these balanced approaches between conservation, development and utilization of marine and coastal eco-systems is needed. To meet the next generation demand it is high time to explore the ocean resources. For this extensive and integrated research can play an important role (Figure 2).

Opportunities of Blue Economy in Bangladesh
Bangladesh is blessed with the Bay of Bengal, the largest Bay in the world. It has massive potentials for the Blue Economy as the coastal states have every right to explore and use resources in their maritime boundaries [15]. Blue Economy provides wide range of services. It offers chances for the clean and sustainable advancement of the marine resources. Some resources are appearing as an emerging sector to develop. All the existing and emerging sectors need to modify for attaining the sustainable growth of the country. Strong relationship was found between poverty eradication and better protection and restoration of habitat, marine fishery resources and biodiversity.

c)
Establishment of a university for further Research Work "BSMR Maritime University".
d) The government are trying to establish a deep-sea port [16].

Conclusion and Recommendations
From the above discussion it can be concluded that, Bangladesh has immense potential to utilize the Blue Economy concept for the betterment of its economy [17]. To attain the expected goal different stakeholders should work together. Some recommendations can be drawn for the successful implement of Blue Economy concept.

a.
Political stability and strong commitments from politicians b. Enough
