Climate induced challenges on the freshwater availability and climate extremes for the Ganges- Brahmaputra-Meghna rivers in Bangladesh at 1.5°C and 2°C global warming

Environmental Change Institute seminar with Prof A.K.M. Saiful Islam, Bangladesh University of Engineering and Technology (BUET).

The Paris Agreement has provided an opportunity to strengthen the global action on climate change. The Paris Agreement emphasizes for limiting global temperature at 2°C and even pursue for 1.5°C above pre-industrial conditions to avoid the potential adverse impact of climate change.
Many recent studies showed that holding global warming to 1.5°C versus 2°C can significantly reduce the potential loss due to climate change. People in South Asia, where people’s livelihoods are highly dependent on water resources, can be affected disproportionally under the warming world. The Ganges-Brahmaputra-Meghna (GBM) river system in South Asia plays a key role in the survival and development of more than 670 million people in South Asia.

In this talk, Professor Islam will show how freshwater availability and climate extremes (e.g. floods and droughts) of the GBM river systems in Bangladesh will likely be affected by global warming at different specific warming levels. An investigation of the change of flows in the GBM river systems using a semi-distributed hydrological model forced by the multi-model ensembles bias-corrected regional climate projections will be presented. This study will assist for the understanding of the potential implications of climate change and adaptation options for agricultural and water resources management of these three river basins in Bangladesh.
