Introduction
Teal Carbon is an emerging concept in climate science, referring to the carbon stored in non-tidal freshwater wetlands. This includes carbon sequestered in vegetation, microbial biomass, and dissolved and particulate organic matter. Recognizing the significance of teal carbon can play a vital role in mitigating climate change by enhancing our understanding of carbon sequestration in freshwater ecosystems.
India’s First Teal Carbon Study at Keoladeo National Park
- Location: Keoladeo National Park (KNP), Rajasthan, India.
- Significance: The study highlights the potential of teal carbon as a tool to mitigate climate change, especially if anthropogenic pollution in wetlands is controlled.
- Findings:
- Elevated methane emissions from wetlands can be reduced using a specialized type of biochar, a form of charcoal that enhances carbon sequestration.
- Managing pollution levels can optimize the carbon storage potential of freshwater wetlands.
About Teal Carbon
- Definition: Teal carbon refers to carbon stored in freshwater and wetland environments, encompassing:
- Carbon sequestered in vegetation.
- Microbial biomass.
- Dissolved and particulate organic matter.
- Color-Based Terminology:
- The term “teal” reflects a classification based on the function and location of organic carbon rather than its physical properties.
- Differentiates from other carbon types by the ecosystems they are associated with.
- Comparison with Other Carbons:
- Black Carbon: Produced by incomplete combustion of fossil fuels; contributes to global warming.
- Brown Carbon: Also results from incomplete combustion of organic matter.
Significance of Teal Carbon
- Climate Change Mitigation:
- Freshwater wetlands are efficient carbon sinks, absorbing significant amounts of COâ‚‚ from the atmosphere.
- Enhancing teal carbon sequestration can reduce greenhouse gas concentrations.
- Environmental Benefits:
- Groundwater Recharge: Wetlands contribute to increasing groundwater levels.
- Flood Mitigation: Act as natural buffers, absorbing excess floodwater.
- Heat Island Reduction: Presence of wetlands can lower surrounding temperatures, supporting sustainable urban adaptation.
- Biodiversity Conservation:
- Wetlands are rich in biodiversity, supporting various species of flora and fauna.
- Protecting these ecosystems ensures the survival of numerous species.
Types of Carbon
Understanding different carbon types is essential for comprehensive climate strategies.
Carbon Storage
- Purple Carbon:
- Description: Carbon captured directly from the air or industrial emissions.
- Methods: Utilizing technologies like Carbon Capture and Storage (CCS).
- Blue Carbon:
- Description: Carbon stored in oceanic plants and sediments.
- Ecosystems: Mangroves, seagrasses, and salt marshes.
- Teal Carbon:
- Description: Carbon stored in freshwater and wetland environments.
- Examples: Marshes, swamps, peatlands.
- Green Carbon:
- Description: Carbon stored in terrestrial plants.
- Ecosystems: Forests, grasslands.
Carbon Release
- Black Carbon:
- Source: Released through the burning of fossil fuels.
- Impact: Contributes to atmospheric warming and health issues.
- Grey Carbon:
- Source: Emitted from industrial processes not related to combustion.
- Examples: Cement production emissions.
- Brown Carbon:
- Source: Produced by incomplete combustion of organic matter.
- Examples: Biomass burning, wildfires.
- Red Carbon:
- Source: Released through biological particles on snow and ice reducing albedo.
- Impact: Leads to increased absorption of sunlight and accelerated melting of ice.
