Along with their tributaries, these rivers drain about 1.75 million sq km of land, with an average runoff of 1,200 cu km. The GBM system also supports over 620 million people. Thus, the need for cooperation on trans-boundary waters is crucial to the future well-being of these millions. That is precisely the motivation for the Ecosystems for Life: A Bangladesh- India Initiative (Dialogue for Sustainable Management of Trans-boundary Water Regimes in South Asia) project. IUCN wishes to promote a better understanding of trans-boundary ecosystems between Bangladesh and India, by involving civil society in both counries and by providing a platform to discuss issues common and germane to the region. The overall goal is an improved, integrated management of trans-boundary water regimes in South Asia. The Ecosystems for Life is guided by a Project Advisory Committee (PAC) of eminent persons from Bangladesh and India. This four-and-a-half year initiative is supported by the Minister for European Affairs and International Cooperation, the Netherlands. Ecosystems for Life will develop, through dialogue and research, longer-term relationships between various stakeholder groups within and between the countries. It will develop a common understanding to generate policy options on how to develop and manage natural resources sustainably such that livelihoods and water and food security improve. Inter-disciplinary research that relevant issues are holistically grasped. studies will be conducted by bringing together experts from various fields from both countries so The initiative centres around five broad thematic areas: • food security, water productivity and poverty; • impacts of climate change; • inland navigation; • environmental security; and • biodiversity conservation.

The initiative, thus, has taken a big step; now, the agenda for meaningful IUCN hopes these publications will be useful to academics, researchers and practitioners in the GBM region.

Even as their overlapping geographies force them to share a climate, with its associated vulnerabilities, their use of common resources like Iwater means that actions in one country can profoundly impact the other. As the impacts of climate change begin to set in, the commonalities in the former will lend greater urgency to the relationship in the latter. As both countries begin to face ever increasing temperatures and ever more erratic this spirit, the International Union for the Conservation of Nature (IUCN) has begun an international precipitation, they will be forced to find greater common cause in their shared water resources.

It was selected due to its incredible importance in terms of supplying water and livelihoods to both countries, while occupying a significant area of India and the entirety of Bangladesh.

Though Nepal and Bhutan are also part of the GBM region, these countries fall outside the scope of study and will be mentioned only when directly relevant. Our purpose is to arrive at a situation analysis of the impacts of climate change in the GBM basin, including the social, environmental and economic implications, especially for India. Additionally, we identify research knowledge gaps, to serve as a guide for future research in climate change and cooperation between India and Bangladesh. The knowledge gaps, described throughout, are taken to that extent, this element of the paper could be considered a sort of meta-study, synthesizing the directly and almost exclusively from the information in prior case studies and literature reviews; knowledge gaps identified by prior efforts.
