This report is an output from the DFID funded project Groundwater resilience to climate change and abstraction in the Indo-Gangetic basin.
Groundwater resilience to climate change and abstraction in the Indo-Gangetic basin is a two-year (2012–14) research project strengthening the evidence-base linking groundwater resources, climate variability and abstraction in the Indo-Gangetic basin. This project has been funded by UK aid from the UK Government, and led by the British Geological Survey, however the views expressed do not necessarily reflect the UK Government’s official policies. The project has two main aims:
- To develop a strategic overview assessment of the occurrence and status of groundwater resources in the Indo-Gangetic basin and develop a map of groundwater typologies spanning the groundwater system
- To strengthen the evidence-base linking groundwater resources, climate and abstraction through a series of four targeted case studies in the basin
The project team involves researchers from the British Geological Survey, IIT Kharagpur, ISET-Nepal, ISET International, Meta-Meta, National Institute of Hydrology (Roorkee), Overseas Development Institute, University College London, University of Dhaka and Bangladesh Water Development Board.

This report is the product of a study by University College London (UCL) in collaboration with the British Geological Survey (BGS), Bangladesh Water Development Board (BWDB), Dhaka University (DU, Bangladesh), Indian Institute of Technology (IIT Kharagpur, India), and Bangladesh University of Engineering and Technology (BUET, Bangladesh). The report describes the findings of a Case Study on Deep groundwater in the Bengal Mega-Delta: new evidence of aquifer hydraulics and the influence of intensive abstraction, a component of the BGS research programme ‘Groundwater resources in the Indo-Gangetic Basin: resilience to climate change and pumping’. The Case Study focusses on the security of deep groundwater in the coastal region of the Bengal Aquifer System (BAS) of the Ganges-Brahmaputra-Meghna (GBM) delta. Regionally, deep groundwater in BAS has acquired strategic importance as a secure water resource for tens of millions of inhabitants of Bangladesh and West Bengal. Population increase, irrigation demand and climate change will combine to increase the stress on the resource in the future. It is hoped that the outcomes of this Case Study will enable a more robust evaluation of the response of deep groundwater in the GBM delta region to increasing development and to climate change.
