India is emerging as a key player in the seaweed industry, leveraging this marine crop not only as a source of organic fertilizers but also as a strategic tool in combating climate change. This development is part of India's broader engagement with the 'blue economy,' which emphasizes sustainable use of ocean resources for economic growth and environmental health. In the wider East Asian region, experts highlight the importance of prioritizing eco-friendly aquaculture practices, such as cultivating bivalves and seaweed, to ensure sustainable growth of vital 'blue food' systems. These systems offer significant nutritional and ecological benefits amid ongoing climate challenges. Additionally, China's initiatives like “Seed to Table” demonstrate how food systems can integrate cultural preservation, farmer empowerment, and biodiversity conservation. The region's rich coastal ties position East Asia to lead the global shift toward sustainable aquatic food production, which is crucial for regional food security and climate adaptation. Meanwhile, Indian scientists are advancing efforts in gene editing to climate-proof plants, further supporting resilience against climate impacts.
