Short Description

Among several promising strategies to arrest declining water tables, underground storing via aquifer storage and recovery (ASR) presents some intriguing possibilities to defuse irrigation tensions in many parts of Bangladesh. The study will attempt to systematically assess the potential of multiple ASR wells in augmenting GW recharge along with improved quality of water, sufficient for subsequent irrigation abstraction in the dry season. Specific objectives are: (1) enhance operational capabilities of ASR against chronic clogging; (2) reduce vulnerability of coastal aquifer via using multiple ASR wells in diluting saline concentration to a tolerable limit for crop production; and (3) training farmers, including women, to maintain ASR wells for resilient water management. Mineralogical and hydrogeochemical aspects of ASR will be examined in detail. The proposed study expects to improve the technical capability of Bangladesh Agricultural Development Corporation (in collaboration) as well as community women to spearhead ASR adoption and application.

Short Description

Aquifer Storage and Recovery (ASR) is a concept of artificial recharge and recently been promoted by Bangladesh Delta Plan 2100. India has many success stories of implementing ASR for increasing cropping intensity by (a) removal of waterlogging, and (b) supplying irrigation cum domestic water. However, no field-based application has yet been attempted in Bangladesh for agricultural purposes. With this aim to increase cropping intensity of Bangladesh, bore well aquifer type ASR is expected to be useful, innovative water management solution for farmers facing drought, water-logged and salinity situations. ASR gets their land free from water logging in peak monsoon and during post-monsoon period allows farmers to access best quality irrigation water at their farming land. ASR is an added benefit along with salinity solution for the coastal region. Thereby, first, the study will explore the opportunity of using ASR set-up in the saline prone coastal area namely, Dacope. Second, it will assess the possibility of using existing STW structures in both recharging and irrigation pumping for the North region (i.e., Nator, Rajshahi, and Tangail) to the current experimental set-up of ASR.

Short Description

Water security problems in mountainous areas are often systemic and rooted in an approach to water security by the local government that gives little consideration to spring-based water management system. Therefore, to avert impending crises of water much progress has been made, in particular, in India and Nepal through Spring-shed management (e.g., Dhara Vikas). In contrast, Bangladesh Government has never been officially exposed to such ideas although has already built several structural interventions addressing the need of using spring water for upland communities. There is a need in Bangladesh to tackle these projects using science and traditional knowledge leading to resource-based spring-shed management approach. Hence, the overall objective of the project is to generate and disseminate knowledge on water security in hard to reach mountainous areas with an environmental security framework. The specific objectives are: i. Developing an environmental security framework for diagnosing the community water security using four interrelated concepts that are availability, access, utility, and stability of water resources. ii. Develop conceptual basis of recharge process at local scale and find out best short term and long term measures for the sustainable water security in the study area based on site observations, hydrogeological parameter analysis and participatory social science research. iii. Knowledge and experience sharing of the local scale concept/learning with Sikkim, India and beyond explicitly accounting water security issues of upland community.

Study on abstraction-induced recharge as an adaptation response to climate variation for shallow aquifer in Bangladesh

Funding Agency

International Foundation for Science (IFS)

Duration

October 2018 - April 2021 (2.5 years)

Researcher from IWFM

Dr. Sara Nowreen

Short Description

The importance of groundwater is expected to heighten in future under the need to offset the substantial ill effects of climate change. The adaptive capacity is important because, while more frequent and intense variability of rainfall will rapidly enhance the risk of significant reduction in the volume of reliable surface water resources, aquifers are likely to be affected much more slowly by the projected climate change. On the other hand, population increase, irrigation demand and climate change in combination will continue to increase the stress on the groundwater resource in the future. Against this backdrop, a PhD study by Nowreen, 2017 proposes piloting abstraction-induced recharge concept (AI-R) as an adaptation option for some probable locations in Bangladesh to meet the un-met water challenges in future. The underlying and implicit assumption of the AI-R concept is that the underground store can be rapidly filled in during the wet season and used up during in the following dry season. But A-IR concept does not have the potential to be applied at the large basin scale in whole Bangladesh but probable locations are already identified at the farm scales by the PhD study of Nowreen, 2017. However, given the concerns over the mobilisation of natural occurring arsenic due to heavy abstraction through pumping, continuing use/increase of irrigation water should be carefully monitored and managed.  One of the most challenging aspects of reviving the A-IR is to maintain the required flows during the low-flow period. This is particularly true, because many stretches of the river already have an unacceptable level of low flows in the dry season.  Therefore, implementation of AI-R would require testing in pilot projects within limited areas. The aquifer condition, response to rainfall events etc. are at least needed to be observed on potential sites where piloting can be attempted.

Short Description

Achieving urban water security, particularly in mountainous regions of Hindu Kush Himalaya (HKH), is a major challenge for sustainable development. Water security problems here in HKH are often systemic but governed by diverse factors with complex interactions among each other. Hence, this study attempts to examine the complex linkages between water security and urban management at a local level of two countries, namely Nepal and Bangladesh learning from the experience of India. The systematic study will (1) identify underlying geographical, climatic, institutional and socio-economic vulnerabilities, (2) assess their impacts on urban mountain communities, and (3) document current and potential adaptation mechanisms to strengthen water security. Unlike indicators-based water security framework, this study will consider perception-based measures applying a mix of participatory research methods namely in-depth interviews and focus group discussions. To collate and analyse data tools like problem and solution tree, seasonal calendars and participatory GIS will be seamlessly integrated into the study. The major outcomes expected from the study include an issue brief that will help in developing framework guidelines for policymakers to engage with local water users for greater collective resource management. The study will also facilitate the sharing of knowledge by exchange visits and train young researchers on linking science with policy through participatory research.

International Foundation for Science (IFS)

Duration

October 2015 - December 2017 (~2.5 years)

Researcher from IWFM

Ms. Sara Nowreen

Short Description

The main objective of the study is to assess the in-stream flow requirement of main and regional rivers of the North-West of Bangladesh. For effective water management, this research project generated maps on current flow variability and trend. The desired level of natural flow of the rivers was evaluated through three methods of hydrological approaches viz., (i) Tennant or Mean Annual Flow method (ii) Flow Duration Curve method and (iii) Constant Yield method. Additionally, Nowreen S also applied the Range of Variability Approach to determine the ecological flow threshold with the help of IHA (Indicators of Hydrologic Alternation) software. It is expected to be a useful reference containing descriptions and evaluations of quantitative instream flow in the context of low land rivers, such as in Bangladesh. Findings of this study are expected to provide a guideline to the organizations involved in planning for water management (i.e., WARPO), river regulation and maintenance (e.g., BWDB), negotiation with upper riparian country (such as JRC) and supporting water sector activities (like IWM and CEGIS). The overall assessment of the dry season water availability will further help in predicting future availability for off-stream uses.
