Mariculture in India essential as seaweeds available in abundance

About 37 percent of our land is agricultural land, out of which 11 percent is used for crops. As the world’s population increases to 9.7 billion in 30 years, the land accessible for yields will diminish. Along these lines, there is a quick need to attempt and improve the productivity of food production.

As per experts, agri yield must see a 50 percent increase from now and 2050. The question, how to do this is what has been troubling scientists across the globe. Plants use sunlight for food production and producing energy for their metabolism. This is referred to as photosynthesis.

However, the effectiveness of photosynthesis is somewhat low, pretty much 5% in most land crops. The most productive land crop with 8% is sugarcane, which isn't too edible if we take out the sugar from it. The One such endeavor is through the task RIPE (Realizing Increased Photosynthetic Efficiency), attempted researchers at the University of Illinois at Urbana-Champaign in the US, bolstered by the Bill and Melinda Gates Foundation.

Genetic Engineering

One method for accomplishing it has been appeared in the model plant tobacco where the researchers could "engineer photosynthesis" by expanding the outflow of three qualities associated with preparing light. This expands the tobacco yield by 20%. The group is attempting to do the equivalent hereditary Genetic Engineering in different plants.

One such plant is cassava (likewise called custard, sago or sabudana) whose roots are starch rich, and eaten by over a large portion of a billion people in Latin America and parts of Africa; it is also eaten as staple nourishment in parts of Andhra, Kerala and the uneven regions of Assam Genetic Engineering of this plant was done, similarly as in tobacco, and seems to work. Another way that some different researchers are attempting is to decrease what is called photorespiration in plants.

Here the vitality and oxygen created in the 'light response' of photosynthesis is depleted by the plant to make "inefficient" items in the 'dull response', and not simply sugars and other nourishment material, especially when the plant's leaves close so as to diminish water misfortune by dissipation. If we can discover approaches to diminish this photorespiration, food yields can go up.

A considerable lot of these examination endeavors include the presentation of outer genes and gene products into food crops, and these are contradicted by some people who don't need Genetic Engineering and genetically adjusted plants. This is inquisitive where science discovers ways to manage qualities in order to improve yields while humanism restricts it dependent on stresses over wellbeing, just as monopolistic control of nourishment material through selective licenses and different variables. A by means of media arrangement should be discovered, falling flat which nourishment generation may not expand all to bolster the regularly developing populace of the world.  

Incorporate sea weed in our eating routine

It is in this setting we have to open our brains and extend our thoughts regarding our sustenance propensities. The most productive utilization of photosynthesis is really not via land plants but rather by small scale and full scale green growth, for example, sea weed. These are the heroes, adding to about half of all photosynthesis on the planet. Furthermore, a considerable lot of them, remarkably those with dull green, red and darker shading, are edible. They are low-calorie and nutrient dense food items and eaten by individuals in many areas of South East Asia – Philippines, Malaysia, Vietnam, Indonesia, China, Korea and Japan, and furthermore in some in Coastal Atlantic region.

Seaweed research

Around 844 seaweed species are accounted for from India, a nation with a coast line of 7,500 km. Peninsular India, Gujarat, Odisha and West Bengal along with Andhra Pradesh, Maharashtra and Goa together have a coast line of 5,200 km, while Andaman and Nicobar together have a coast line of 2,500 km. Consequently, while we have 63% of our land for crop agriculture, we ought not overlook this tremendous coastal zones, a lot of which breeds sea weed. Research in the region of eatable sea weed in India has been continuing for more than 40 years.

The Central Salt and Marine Chemicals Research Institute (CSMCRI) at Bhavnagar, Gujarat has done spearheading work in the subject. Prof. CRK Reddy, who was at CSMCRI for a considerable length of time and right now at the Institute for Chemical Technology, Mumbai, has been an advocate of sea weed to be used as food. He calls attention to that among the sea weed found in bounty, Ulva, Pyropia, Porphyra and Kappaphycus are edible and that it will be a great idea to develop them in expansive scale, as is done in nations like Japan.

Also, out of 306 sea weeds in the Gulf of Mannar, 252 are edible. Therefore, it is essential for India to embark Mariculture as much as Agriculture, given its 7,500 km-long seaside line. Further, it doesn't require pesticides, manures and water for water system, which is an additional preferred standpoint.
