Satellite based methane Alert and Response System

A new satellite-based Methane Alert and Response systemhas been launched at the 27th Conference of Parties (COP27)to help governments detect methane emissions and tackle them.

Methane Alert and Response System (MARS):

• MARS is a part of global efforts to slow climate change by tackling global warming gas.
• It will use state-of-the-art satellite data to identify significant emission events, notify relevant stakeholders, and support and track mitigation progress.
• MARS will integrate data from the rapidly expanding system of methane-detecting satellites to include lower-emitting area sources and more frequent detection.
• Data on coal, waste, livestock, and rice will be added gradually to MARS to support the Global Methane Pledge
  • India has not signed up for the Global Methane Pledge.
    
    

Components of the Methane Alert and Response System:

• MARS will use data from global mapping satellites to identify very large methane plumes and methane hot spots and data from high-resolution satellites to then attribute the emissions to a specific source.
• UNEP(United Nations Environment Programme) will then notify governments and companies about the emissions, either directly or through partners, so that the responsible entity can take appropriate action.
• If requested, MARS partners will provide technical or advisory services such as help in assessing mitigation opportunities.
• UNEP will continue to monitor the event location and make the data and analysis available to the public between 45 and 75 days after the detection.

Steps taken to Curb Methane Emissions:

• COP 26 Pledges: At COP26 in Glasgow, over 100 countries signed an agreement to cut methane emissions by 30% by 2030.
• The US President has announced the Global Methane Pledge, which is a US-EU-led effort to cut methane emissions by a third by the end of this decade.
• MethaneSAT: Controlling methane emissions will require further scrutiny of its sources. To this end, satellites that will track methane leakage such as MethaneSAThave been planned to launch.
• The International Energy Forum (IEF) launched the IEF Methane Initiative in June 2021 to develop a methane emissions measurement methodology.

India's methane emissions and mitigation initiative

• Global Methane Initiative (GMI) website, India ranks fourth, and its methane emissions are nearly one-third that of China.
  

  SPECIES IN NEWS
  Manta rays	Context:Scientists have found a huge group of manta rays off the coast of Ecuador. The group has more than 22,000 manta rays, more than 10 times the population estimates in other regions.  About Manta rays (Mobula birostris) are the largest rays in the world. Shape: large, flat, diamond-shaped bodies, which are characterised by triangular pectoral fins. Manta rays have two horn-shaped fins protruding from the front of their heads, which has also given them the nickname "devil fish". Habitat: The sea creatures are found in in tropical, subtropical, and temperate ocean waters across the globe. Conservation Status: In 2019, the manta rays again entered the endangered list of the International Union for Conservation of Nature (IUCN).
  Indian Elephant (Elephas maximus indicus)	Context: Tamil Nadu’s Forest Department has introduced an elephant death audit framework to put in place a more detailed and transparent process for recording and monitoring elephant deaths in the State. Species:There are three subspecies of Asian elephants – the Indian, Sumatran, and Sri Lankan. Protection Status: ‘Endangered’ as per the IUCN Red List. Threats:Habitat loss, Degradation, and Fragmentation
