Assessment of Methane Variability from Natural Wetlands of Uttar Pradesh, India-Implications for Tropical Countries

Tropical wetlands are one of the most dynamic natural sources of atmospheric methane (CH sub( 4)) but the CH sub( 4) emission data is still scanty to quantify and elaborate the process of CH sub( 4) emissions from natural freshwater tropical wetlands. In view of this, the present study attempts to estimate the CH sub( 4) emissions from two natural tropical wetlands of Uttar Pradesh, India to further augment the CH sub( 4) emission database for tropical countries for improved understanding of CH sub( 4) cycling in tropical wetlands. This study elucidates the importance of temporal, site specific and zone-wise dependence of CH sub( 4) emission in a wetland. Significantly higher CH sub( 4) flux in the summer season than monsoon and winter season at both the locations (p
