Carbon Sink / Carbon Sequestration

Carbon Sink / Carbon Sequestration क्या है?

A carbon sink is any natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.

Carbon Sinks & Sequestration: Mechanisms & Relevance

This mind map outlines the key aspects of carbon sinks and sequestration, differentiating between natural and artificial methods, their role in climate mitigation, and India's strategic initiatives.

Evolution of International & Indian Carbon Sink Policies

This timeline traces key international agreements and India's significant commitments related to carbon sinks and climate action, highlighting the increasing global focus on sequestration.

ऐतिहासिक पृष्ठभूमि

The concept gained prominence with increasing awareness of anthropogenic CO2 emissions and their role in global warming, especially since the late 20th century. International efforts like the Kyoto Protocol (1997) and Paris Agreement (2015) emphasized the importance of carbon sinks.

मुख्य प्रावधान

8 points
  • 1.

    Natural Carbon Sinks: Oceans (absorb a significant portion of atmospheric CO2, e.g., Southern Ocean absorbs approximately 40% of human-emitted CO2) and Forests and Soils (plants absorb CO2 during photosynthesis, storing carbon in biomass and soil organic matter).

  • 2.

    Artificial Carbon Sinks / Carbon Capture and Storage (CCS): Technologies designed to capture CO2 from industrial sources and store it underground in geological formations.

  • 3.

    Role in Climate Regulation: Carbon sinks help mitigate climate change by removing CO2 from the atmosphere, thus reducing the greenhouse effect.

  • 4.

    Saturation Risk: Natural sinks can become saturated or even turn into sources if environmental conditions change (e.g., deforestation, ocean warming).

  • 5.

    Blue Carbon: Carbon stored in coastal and marine ecosystems like mangroves, salt marshes, and seagrass beds, which are highly efficient carbon sinks.

  • 6.

    Carbon Cycle: Sinks are integral to the global carbon cyclethe biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

  • 7.

    Afforestation and reforestation are key strategies to enhance terrestrial carbon sinks.

  • 8.

    The efficiency of carbon sinks can be influenced by factors like ocean stratification and ocean currents.
