4th Global mass coral bleaching in Great Barrier Reef (GBR)

The US National Oceanic and Atmospheric Administration (NOAA) has said that the world is on the brink of a fourth global mass coral bleaching event which could see many tropical reefs killed by extreme ocean temperatures, including parts of Australia’s Great Barrier Reef.

  • Corals - Marine invertebrates or animals which do not possess a spine.
  • They are the largest living structures on the planet.
  • Each coral is called a polyp and thousands of such polyps live together to form a colony.
  • Corals share a symbiotic relationship with single-celled algae called zooxanthellae.
  • Coral Bleaching - When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white.
  • When a coral bleaches, it is not dead, they are under stress and are subject to mortality.

To address a defined need of coral reef managers around the world, NOAA established the Coral Reef Watch (CRW) program in 2000.

Bleaching in GBR

  • The Great Barrier Reef, the largest coral system in the world, is about 2,300km long and is made up of about 3,000 individual reefs.

The Great Barrier Reef is one of the natural wonders of the world and was inscribed on the World Heritage List in 1981 for its unique natural attributes and enormous scientific and environmental importance.

  • The current mass bleaching event occurred as a result of El Nino conditions in the Pacific Ocean and elevated ocean temperatures exacerbated by climate change.

El Niño is a natural climate cycle characterized by warmer-than-usual waters in the Pacific Ocean, typically increases average air and sea temperatures and can have a significant effect on rainfall, hurricanes and other severe weather.

  • Previous mass bleaching events - 1998, 2010 and 2014-2017.
  • The World Heritage Committee has threatened to put the reef on a list of in danger global heritage sites.
  • GBRMPA - The Great Barrier Reef Marine Park Authority (GBRMPA), which was established in 1975, oversees the efforts to preserve and protect the GBR.

The world’s most southerly coral reef, at Lord Howe Island off Australia’s New South Wales coast, is also being hit by coral bleaching.

Trade Secrets

The 22nd Law Commission headed by Justice Ritu Raj Awasthi has recommended a legislation to protect trade secrets with a provision to protect whistle-blowers.

  • Trade secrets – According to World Intellectual Property Organization, “Trade secrets are intellectual property (IP) rights on confidential information which may be sold or licensed”.
  • Unlike other forms of intellectual property, which are limited in duration, trade secrets can be protected indefinitely.
  • Criteria to qualify a trade secret – To qualify as a trade secret, the information must be:
    1. Commercially valuable,
    2. Be known only to a limited group of persons,
    3. Be subject to reasonable steps taken by the rightful holder of the information to keep it secret, including the use of confidentiality agreements for business partners and employees.
  • The unauthorized acquisition, of such secret information in a manner contrary to honest commercial practices by others is regarded as an unfair practice and a violation of the trade secret protection.
  • Regulation of trade secrets - Currently, India lacks a specific law for the protection of trade secrets.
  • Instead, they are safeguarded under the general laws governing contracts, common law, criminal law, and principles of breach of confidence and equity.
  • National Intellectual Property Rights Policy, 2016, and the Parliamentary Standing Committee Report have brought back focus on the need for introducing legislation to deal with trade secrets.

Law Commission of India is a non-statutory body and is constituted by a notification of the Government of India, Ministry of Law & Justice, Department of Legal Affairs to make recommendations to the Government in the form of Reports.
