Kappaphycus alvarezii

A report released on March 16, 2023, has revealed that the Gulf of Mannar Marine National Park, situated in Ramanathapuram, Tamil Nadu, is currently experiencing a concerning coral breach due to the invasive seaweed species Kappaphycus alvarezii.

  • 20 years ago, the intentional introduction of Kappaphycus alvarezii for commercial cultivation took place in Ramanathapuram, Tamil Nadu.
  • Currently, 750 farmers in 18 villages of Ramanathapuram engage in seaweed farming, primarily Kappaphycus.
  • Kappaphycus grows rapidly and seeks out live corals to thrive on, unlike native seaweeds that typically grow on dead corals.
  • The International Union for Conservation of Nature has listed Kappaphycus as one of the world's 100 most invasive species.
  • The Indian government has allocated INR 600 crore to increase seaweed production to 11.85 million tonnes by 2025, which could exacerbate the invasive seaweed problem in the Gulf of Mannar.
  • The government's plan to set up a seaweed park in Tamil Nadu could lead to further spread of Kappaphycus.

Megha-Tropiques-1 (MT1)

On March 7, 2023, the Indian Space Research Organisation (ISRO) conducted a successful controlled re-entry of its decommissioned satellite, Megha-Tropiques-1 (MT1).

Megha-Tropiques-1 (MT1) satellite, launched jointly by ISRO and the French space agency, CNES, on October 12, 2011, was designed for tropical weather and climate studies.

  • Exceeding Mission Life: Despite exceeding its three-year mission life, MT1 continued to provide valuable data services for over a decade, supporting regional and global climate models until 2021.
  • Space Debris Mitigation: In line with the Inter-Agency Space Debris Coordination Committee (UN/IADC) space debris mitigation guidelines, ISRO identified an uninhabited area in the Pacific Ocean between 5°S to 14°S latitude and 119°W to 100°W longitude as the targeted re-entry zone for MT1.
  • Significance:The successful controlled re-entry of MT1 has made a significant contribution to the mitigation of space debris risks, as well as to ensuring the safe operations of future space missions.
