Abstract

The Hindu-Kush Himalaya region’s land cover is comprised of 54% rangeland, 25% agricultural land, 14% forest, 5% permanent snow and 1% water bodies. The Himalayans contain some of the largest water reservoirs, which are critical for HKH countries. Amidst these, wetlands have remained important to ecosystem services and the overall water cycle of the basins. Beside their cultural and provisioning amenities, wetlands are important carbon reservoirs, accounting for 20–30% of the global carbon pool. They act as a sink for atmospheric carbon, thus can influence GHG emissions, especially CH4, and, thus, should be managed properly. However, substantial data gaps remain in quantifying carbon sequestration and the potential of CH4 emission. Furthermore, studies on CH4 fluxes in high-altitude wetlands, particularly in remote areas, remain inconclusive. Hence, more research is required to understand the role of wetlands in term of GHG emissions and carbon sequestration.
