DECCMA Bangladesh PI leads seminar on how sediment load affects the nature of the Ganges-Brahmaputra-Meghna delta

by Institute of Water and Flood Management

DECCMA PI Professor Munsur Rahman led a seminar on ‘Recent sediment flux and its implications for river and delta management in the Ganges-Brahmaputra-Meghna system’ on 3rd April at the Institute of Water and Flood Management (IWFM) at the Bangladesh University of Engineering and Technology.

Sediment flux is the mechanism that creates the nature of a delta, and thus is essential for river and delta management. The physical sustainability of the river and delta environment is very  sensitive to the volume of water and sediment that arrives from rivers upstream. In most of the planning documents in Bangladesh, the total sediment flux is assumed to be a constant value of around 1 billion tones per year. Recent models shows that, under climate change, there is likely to be an increase in sediment flux. However, this contradicts historical time series data, that shows a decreasing trend of sedimentation.

Studies on the total sediment load in the Ganges and the Brahmaputra show that the quantity transferred along the bed of the river is decreasing more rapidly than the sediment that is suspended within the water. A reduction in sediment within the system reduces the scope for  offsetting future sea level rise, and thus has implications for subsidence and loss of land.

Recognising the importance of sediment quantity and flows in thus essential to manage the delta. The seminar concluded by emphasising the need for discussion and negotiation on sediment flux and water sharing to reduce the effect of dams upstream within Bangladesh and neighbouring countries. Along with the faculty members of IWFM guests from relevant organisations were also present, including Bangladesh Water Development Board, the Directorate of Bangladesh Haor and Wetland Division, Local Government Engineering Department, Centre for Environmental and Geographic Information Systems and the Bangladesh Export Processing Zones Authority.

DECCMA and HI-AWARE jointly convene stakeholder workshop with WARPO to disseminate Bangladesh research findings

by Saiful Alam

A joint stakeholder workshop was arranged by DECCMA and HI-AWARE to present Bangladesh research findings. The meeting took place at the Water Resources Planning Organisation (WARPO) in Dhaka on 17th January 2018. Attendees included the Ministry of Water Resources, Ministry of Forest and the Environment, Ministry of Finance, Ministry of Planning, Housing Authority, Local Government Division, and UNDP.

DECCMA Bangladesh Principal Investigator, Professor Munsur Rahman, and Co-Principal Investigator, Professor Mashfiqus Salehin, made a joint keynote presentation on ‘Adaptation and Migration in GBM Delta, Bangladesh’. HI-AWARE Bangladesh Principal Investigator, Md. Abu Syed, made a keynote presentation on ‘Climate resilience and adaptation in Teesta sub-Basin of Brahmaputra Basin’.

Stakeholders provided inputs to highlight their particular areas of interest in DECCMA findings. Among the key themes were an understanding of the reasons for migration, quantifying negative and positive impacts, and projections for the future-to add to those already outlined in the Delta Plan 2100. There was also interest in modelling the impact of climate change on the economy, as is being undertaken within DECCMA, led by the Bc3 Basque Centre for Climate Change, and supporting the use of models at local (upazila) level.

“An environment for wellbeing: Pathways out of poverty”-learning from the Ecosystem Services for Poverty Alleviation programme

Ecosystem Services for Poverty Alleviation (ESPA) is a global interdisciplinary research programme that began in 2009 with the aim of giving decision-makers and natural resource users the evidence they need to address the challenges of sustainable ecosystem management and poverty reduction. The programme was developed by the UK government in response to the findings of the 2005 Millennium Ecosystem Assessment that substantial gains in human well-being in recent decades have been achieved at the expense of high and often irreversible levels of ecosystem degradation.

This short film highlights some of ESPA’s findings on the role of ecosystem services in diversifying livelihood options for vulnerable people, the contribution of sustainably managed ecosystem services to national wealth (and related poverty reduction), and insights into how to better manage ecosystems to deliver sustainable, green and inclusive growth. It features insights from ESPA Deltas and ECOLIMITS, looking at the ecological limits of poverty alleviation focusing on smallholder coffee farmers in Ethiopia, and cocoa farmers in Ghana.

Dr. Bazlul Haque Khondker and Zubayer Hossen from SANEM presented DECCMA’s economic framework. This involved the use of stakeholder consultation to provide insights into the Input-Output table of Computable General Equilibrium model in explaining its linkages with livelihood, income and other economic parameters in the agriculture-dominated coastal environment.

Panelists Dr. Anwara Begum, BIDS and Mr. Saiful Alam, DECCMA, discussed the gender dimensions of adaptation and how the research findings on livelihoods and adaptation can influence climate-related policy and planning in Bangladesh. In an open discussion, the panelists answered a number of question from the audience related to the relevance to climate policy and the Sustainable Development Goals.

ESPA Deltas project publishes short film on creating a sustainable future for climate-vulnerable deltas

The Ecosystem Services for Poverty Alleviation Delta Project has just published a short film that highlights its findings in Bangladesh. The project was concerned with assessing health, livelihoods, ecosystems and poverty alleviation in populous deltas to provide knowledge and tools to enable policy-makers to evaluate the effects of policy decisions on people’s livelihoods.

A multidisciplinary and multi-national team of policy analysts, social and natural scientists and engineers collectively used a participatory approach to create a model to formally evaluate ecosystem services and poverty in the context of the wide range of changes that are occurring. In the film, DECCMA Principle Investigator Professor Robert Nicholls and researcher Dr Helen Adams talk about the environmental and social stresses facing delta populations, from salinity and subsidence to poverty and marginalisation.

ESPA Deltas holds final workshop with the Planning Commission in Bangladesh

by Saiful Alam

DECCMA builds on a project under the Ecosystem Services for Poverty Alleviation (ESPA) programme – ESPA Deltas. Following closure of ESPA Deltas in 2016 policy-makers in Bangladesh requested support in the use of tools developed within the project to assess the implications of government project proposals on ecosystem services and livelihoods in coastal Bangladesh. An additional year of funding was granted to ensure that the developed research could be translated into use to inform policy.

Bringing together research to inform disaster risk reduction in Bangladesh

by Saiful Alam, DECCMA Bangladesh RiU focal point, BUET

Ensuring university research feeds into policy and practice is key to reducing disaster risk reduction. DECCMA is building evidence on how climate change is affecting deltas, how people are adapting to these changes, and the role of migration.

In Bangladesh the Institute for Water and Flood Management (IWFM) at the Bangladesh University of Engineering and Technology is participating in a platform to bring together research and knowledge generated by universities to strengthen capacity for improved water management and disaster risk reduction. This sits under the project “Research on Disaster Prevention / Mitigation measures against Flood and Storm Surges in Bangladesh” (SATREPS).

As part of its efforts to disseminate research findings, IWFM organized a University Networking workshop in August 2017 to present five training modules developed under the SATREPS project with the aim of building capacity at the field level. The five modules discussed topics relating to flood management and disaster risk reduction:

  1. Evolution of flood management policy and planning
  2. Evaluating resilience against flood disaster
  3. Learning from experience of NGOs in disaster management
  4. Review of measures for river flood management in Bangladesh
  5. Flash flood risk management using information and communication technologies in Bangladesh

The workshop was attended by researchers from 19 universities in Bangladesh and further afield. DECCMA Bangladesh PI, Prof. Munsur Rahman, outlined findings from DECCMA. He also called for joint action-oriented research with emphasis on governance to reduce disaster risk among vulnerable delta populations.

Following from this successful workshop, another will be planned to further disseminate DECCMA research findings on vulnerability hotspots and adaptation. This will likely take place at Potuakahi University of Science and Technology, and further details will be available on the DECCMA website when a date has been finalised.
