Abstract

Fluxes of methane (CH₄) were measured in situ monthly for two years from a tropical shallow urban pond, receiving influx of agriculture run-off from the surrounding water shed and domestic sewage, located in Ujjain city, Madhya Pradesh. The Tropical Dry Deciduous Forest dominated by Tectona grandis (Teak plants) is located 20Km southwards from Indore. Results revealed that the shallow pond is a continuous source of (CH₄) with highest annual methane emission rates (mean 4308.15 Kg ha⁻¹ yr⁻¹). In contrast to Wetland, the natural site Tropical Dry Deciduous forest is found to be the strongest sink for methane showing annual methane consumption rates (mean-20.35,-24.55 Kg ha⁻¹ yr⁻¹). Several influencing factors like pH, temperature, inorganic nitrogen and organic carbon were studied concomitantly with CH₄ fluxes. CH₄ emissions were positively and significantly correlated with sediment organic matter in wetland and soil moisture in the forest. The study conclude that the shallow tropical water body is a source of CH₄ flux and also point out the importance of natural plant community as key player to act as sink for methane, the important green house gas.
