Should we start to rethink urban agriculture and food supply?


The sea is called the lungs of the earth. The land under the sea is a world full of diversity and abundance of life. Professor Gunter Pauli, an Australian citizen, gave a first idea of ​​the enormous economic potential. In 2010, at the invitation of the United Nations, the idea of ​​formulating a sustainable economic framework that respects the environment was expressed in his speech.

Blue economies are the water resources of the oceans, the resources of the oceans, and the economies that surround the oceans. Blue Economy means that the color of the sea is blue. This is why the sea-centric economy is called the blue economy. The main components of the blue economy are mineral resources, water resources, transport services, energy resources, tourism industry, etc. The planned use and sustainable development of these resources will bring enormous potential to the maritime economy. Like other countries in the world, Bangladesh will be able to use its marine resources for its economic development.

Bangladesh has already established absolute sovereignty and sovereignty over 1,17,173 km² of waters of the International Court of Justice (ICJ) on March 14, 2012 over the Bay of Bengal dispute with Bangladesh and Myanmar through conquest history of the sea. The mineral resources of the Bay of Bengal in the south of our country are not found in any other sea or bay in the world and it is said that whoever controls the Bay of Bengal will control all of South Asia . This is why the superpowers are trying to occupy the Bay of Bengal.

The blue economy is becoming more and more popular around the world today. By 2050, the world’s population will be around 950 million. We have to look at marine resources because we are forced to provide food for this huge population. The developed nations of the world are already exploiting marine resources and increasing their economic growth. Ninety percent of Indonesia’s national economy depends on the sea, and the government has already taken steps to ensure that, if implemented successfully, the value of resources extracted from the sea would be 10 times over budget. Australia currently derives $ 44 billion from its marine resources. Now the question is, what are the future prospects of the blue economy in the dark bay of Bangladesh’s maritime resources, how will Bangladesh be able to create jobs through the blue economy and what will be the future economy of Bangladesh ??

There is a ravine-like area in the Bay of Bengal in Bangladesh which is about 6 km long and is known as a fish sanctuary. There are 450 species of fish, 337 species of snails and oysters, 6 species of turtle, 36 species of shrimp, 10 species of dolphin and 5 species of lobster in the Bay of Bengal. These include the economic demand for snails, snails, crustaceans, crabs, octopus and sharks, and are widely regarded as food in many countries. There are also sea grasses, lianas, shrubs. Medicinal weeds of the Bay of Bengal are processed to make medicines for various diseases and among these weeds, Espirulin is the most valuable which is consumed as food in China, Japan and various European countries. It is possible to make different types of sauces, bitumen, etc. from marine fish with food, fish oil, which will create jobs and bring in huge amounts of foreign exchange. There is also a high demand for tuna in the Bay of Bengal.

According to the Bangladesh Atomic Energy Commission, the total mineral reserves of beach sand are 4.4 million tonnes. Of this total, the actual stock is 16 lakh 44,000 tons. Out of 16 types of minerals in the Bay of Bengal, there is a possibility of mining 1 million tons of mineral sand in 13 places. Molybdenum, manganese, crust, copper, lead, zinc, sulphide are found in the deep seabed, and clay raw materials from the cement industry have been found 30-60 km deep at the bottom from the sea. Monazite is a very valuable substance in mineral sands and is used in atomic bombs and nuclear reactors. At the bottom of the Bay of Bengal are ores called edible manganese, deposits of phosphorus, polymetallic sulphide. These ores refine rare metals, including cobalt and lead, and can be used in shipbuilding and chemical factories. There are also gems, pearls, gold, silver, corals and other precious stones.

Precious metals like uranium and thorium have been found in the deep and shallow seas of the Bay of Bengal. It is expected that 1 to 5 metric tonnes of salt will be exported if advanced technology is used in the production of good commercial salt along the coast. Black gold is found in Maheshkhali, Teknaf, Nijhum Island, Kuakata in Cox’s Bazar, which affects our economy.

It is dark in the gas field of the Bay of Bengal. There are 200 trillion cubic feet of gas reserves in 23 blocks of the Bay of Bengal from which rupee crores can be earned.

There is a potential tourism industry around the Bay of Bengal. Various industries will be formed around this industry and there will be huge jobs. Millions of tourists will flock to enjoy the natural beauty of the Bay of Bengal.

There is a possibility of increasing international trade through the Bay of Bengal. Bangladesh already builds ships to international standards and exports them abroad and currently Bangladesh is in 3rd position in ship exports. The shipbreaking industry is also gaining popularity around the world.

Businesses can grow locally and internationally with resources extracted from the sea. The demand for local products in the markets of Cox’s Bazar and Kuakata is high among tourists. The demand for this specialty has increased dramatically following recent corporate scandals.

The blue economy is not only the expansion of the ocean economy, but also the opening of new environmentally friendly horizons by mitigating the risks of climate change. In addition, the role of the sea in reducing poverty, increasing capital flows, developing investment-friendly and environmentally friendly infrastructure, reducing unemployment, creating jobs, he elimination of regional and gender disparities and sustainable development is immense. About 80 percent of the world’s food, livelihoods and trade is carried by sea.

It is possible to implement the blue economy by properly using the resources of the Bay of Bengal in Bangladesh. The Bay of Bengal is considered to be Bangladesh’s “jewel mine”. The Bay of Bengal, in the heart of Southeast Asia, is of great commercial importance because it is easy to communicate with different countries. The government of Bangladesh has already established an “Oceanographic Research Institute” in Cox’s Bazar district to advance the blue economy. Once again, the maritime economy has been a priority in the Bangladesh Delta Plan-2100 master plan. The Blue Economy Cell was formed in 2014. Therefore, with the proper use of the resources at the bottom of the Bay of Bengal, the wheel of Bangladesh’s economy will turn and the future looks bright.
