Seaweed production in India
- Out of the global seaweed production of ~ 32 million tons fresh weight valued around 12 billion US dollars. China produces ~57 %, Indonesia ~28% followed by South Korea.
- India is having a mere share of ~0.01-0.02%.
- Despite several advantages, commercial seaweeds cultivation has not been taken place in the country at an appropriate scale, as being practised in South-East Asian countries.
- By an estimate, if cultivation is done in ≈10 million hectares or 5% of the EEZ area of India, it can provide employment to ~ 50 million people.
- Seaweed cultivation also enhances ocean productivity, abates algal blooms and sequesters millions of tons CO2.
