Source-sink inventory of greenhouse gases from Indian mangroves: a review

Abstract

Present study inventorises quantitative evaluation of greenhouse gas (GHG) emissions from various mangrove ecosystems distributed along the Indian coast. Inconsistency in terms of methodological aspects of GHG flux estimations from Indian mangrove ecosystems along with the variation in space and time, has been tried to be pointed out in this present paper. Inventorization of existing resources available from mangrove ecosystems along the east and west coast of India, would be useful for estimating the future potential ecosystem capacities for fluxes of CO₂, CH₄ and N₂O. This review further confirms the potential role of Indian mangrove waters and sediments as perinial source for GHGs, whereas the canopy (vegetation) particularly acts as a CO₂ sink.
