Introduction
Results
Deforestation and carbon emission
Background
India has committed to create an additional carbon sink of 2.5 to 3 billion tonnes of CO2 equivalent by 2030 in the Intended Nationally Determined Contribution (INDC) submitted to the Paris meet COP 21 (Conference Of Parties).
An IPCC Tier II analysis of different mangrove sites of India will give a better snapshot of role of mangrove cover as carbon sinks to combat climate change and to achieve national target of carbon sink increase.
Objectives:
A comparative assessment of mangrove extent and health study of mangrove sites of India is not done.
calculate Tier II estimation of carbon emission due to deforestation of above ground biomass alone for a time period of 2001 to 2016.
investigated the health of mangrove vegetation along with Land surface temperature
NDVI time series trend
Data and Methodology
Data  
NDVI (Normalized Difference Vegetation Index) and LST (Land Surface Temperature) derived from Landsat
Methodology
In this study, mangrove cover at sites of Sundarbans and Gujarat is analyzed using Landsat imagery employing supervised classification techniques. Vegetation index, Landsurface temperature are also extracted from the same.
Carbon emission value from deforestation at two mangrove site is assessed using carbon stock value from literature. A time serries analysis is done for two sites employing NDVI and LST value.
LST time series trend
Conclusion
Sundarbans along the east coast of India undergo comparatively higher deforestation owing to different natural and anthropogenic threats than the mangroves in Gujarat which shows very little deforestation.
A higher carbon emission profile is observed for Sundarbans site.
Gujarat site have comparatively poor mangrove vegetation health and show a degrading trend.
LandSurface temp of mangrove site of Gujarat is lower than that of Sundarban site
Sub-national level analyse for strategic knowledge base aid to policy making to adhere to INDC proposal and combat climate change.‘’
