Professor Robert Nicholls made a presentation on “Deltas in the Anthropocene” in the SourceToSink series. The presentation highlighted key findings from the ESPA Delta and DECCMA projects and outlined what the future of deltas might look like.
Fieldtrip to the Indian Bengal delta
by Sumana Banerjee
On March 7th 2020, three DECCMA colleagues-Katharine Vincent, Tuhin Ghosh and Sumana Banerjee-embarked on a visit to the Indian Sundarban Delta. This activity was undertaken as a scoping visit for a potential small project which aims to look into the gender-responsive adaptation in the delta.
The team tested some key findings on adaptation which emerged from the household surveys undertaken in DECCMA and learnt about people’s development aspirations, and how they can be made resilient in the context of a changing climate.
Focus groups (held separately with women and men) in two villages of two different islands and key informant interviews with the local governance and practitioners helped in adding richness and depth to explain the quantitative data obtained through DECCMA’s household survey. They also exposed some gaps which would have otherwise been filled in with external (false) assumptions.
As well as giving the research team the opportunity to validate research findings, they also helped in shaping ways of working forward in the project. The team took the opportunity to learn from people how they would like to receive messages relating to climate adaptation based on findings from DECCMA.
Needless to say, like any other good fieldtrip, this was an enriching experience and the team looks forward to get back to the field again to share the findings and design messages to appropriately deliver to the knowledge users to enable gender-sensitive adaptation.
DECCMA remembers Dr Amrita Patel, 1965-2020
It is with great sadness that we announce that Dr Amrita Patel, from DECCMA consortium member Sansristi, passed away in January 2020. Amrita was part of the Mahanadi delta team and played a key role in Work Package One on stakeholder engagement and governance. She was also a valued member of our gender team. Her colleagues offered the above tribute.
New book from DECCMA sister project ESPA Deltas
A new open access book “Integrated Assessment for the Bangladesh Delta Plan 2100: Analysis of selected interventions“, edited by Munsur Rahman, Robert Nicholls, Susan Hanson, Mashfiqus Salehin and Shamsul Alam has just been published.
The book reports analysis undertaken as part of the ESPA Deltas project. Many of the project’s findings are integrated into the Delta Dynamic Integrated Emulator Model (ΔDIEM), which is designed to analyse the present and future of the delta in a policy relevant way in order to benefit the ecosystems, livelihoods and people of the Ganges-Brahmaputra-Meghna delta.
A pilot application of ΔDIEM was trialed based on selected proposals in the BDP 2100, in partnership with the Bangladesh Planning Commission, to assess selected development options being considered as part of the BDP 2100. The new polders in the south central district appear most beneficial both in terms of enhancing incomes and removing people from poverty. However, trade-offs with neighbouring regions due to displaced flooding need to be evaluated and suitable compensatory measures undertaken. The results also show that good maintenance of the existing polder embankments across the region is likely to maintain agriculture and associated livelihoods over the next few decades.

Reflections on research ethics in DECCMA
by Sumana Banerjee, DECCMA India coordinator
During the past 4.75 years, DECCMA created plenty of opportunities for interaction with communities. When interacting with communities, the question of ethics comes into the minds of researchers and funders.
When researchers from universities in the UK visited delta communities in India, they had detailed participant information sheets, consent forms, and debriefing notes as a part of their universities’ ethical requirements to conduct interviews with communities. Most Indian universities do not have such processes in place. For us in Jadavpur University, the only ethical consideration form available is used by the Department of Pharmacy for clinical trials. This does not mean that we did not follow any ethical processes while interacting with communities. We had designed simplified forms to cover all bases for ethics, such as anonymity of participants, non-disclosure of their personal details, freedom to withdraw from the interview at any point, contact persons in case they have queries or requests after the interviews etc. and we also resorted to recording verbal consent at times. Now the difference in institutional processes put me in a reflective mood.
Having detailed paperwork as proof of following the guidelines and getting signed consent from participants is indeed a great process. However, based on our experience of working with delta communities in India (West Bengal and Odisha), we faced some practical challenges while executing this process, two of which are outlined below along with the solutions we used:
Challenge – Mentioning contact details of researchers and their supervisors based in the UK is mandatory but this will have no real meaning for the communities as they won’t obviously email (!) nor have the resources to converse with them if they have questions.
Solution – Include contact details of the organisation closest to the participants who are involved in this research, alongside the mandatory mention of the UK researchers and supervisors.
Challenge – The research team explains every detail about the purpose of their visit but there are instances when the respondent feels nervous to sign a paper since the fear of “losing something” lurks in their minds. Also, by handing a pen to an illiterate person to sign we end up reinforcing hierarchies.
Solution – It is important to make it clear that no harm would be brought upon them by consenting to participate by sharing how the researcher does not collect their personal details (government ID numbers etc.) and how the researcher is also bound to maintain the anonymity of the respondents. Handing out a stamp pad along with a pen is often a better idea and gives the respondent the comfort of choosing the appropriate tool without them having to explicitly announce if they are literate or illiterate.
Ethics is not limited to these processes alone. It is the duty of any person who interacts with communities for their work, to keep in mind the basics of moral human behaviour. Focus on vulnerable communities at times leads to teams being extractive and manipulative in their interactions. Staging a scene for a photograph interrupting the daily schedule of a respondent, or coaxing them to say what one wants to hear to support already formed ideas are unethical. Research teams should avoid such practices at any cost and if the team is responsible for any other actor who resorts to such practices, it should immediately be discouraged. These actions not only hamper the trust built with the community, but also reduce the possibilities of fruitful interactions in the future.
As research teams and most importantly as human beings, it is our responsibility to try and reduce the vulnerabilities of communities we work with and not reinforce differences. To conclude my reflections, I share the following quote where the poet sums it up beautifully –
“By plucking her petals you do not gather the beauty of the flower.”
― Rabindranath Tagore, Stray Birds
ASSAR launches MOOC on Research for Impact
DECCMA’s sister project in the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), Adaptation at Scale in Semi-Arid Regions (ASSAR) has launched a Massive Open Online Course (MOOC) on Research for Impact. The MOOC, available on Coursera, is convened by the University of Cape Town and Oxfam GB and comprises three main learning objectives:
Understand the key interwoven elements of Research for Impact in the context of development and adaptation research.
Identify the suite of activities involved in Research for Impact.
Appraise opportunities in your research plan through an Research for Impact lens and identify challenges applying a Research for Impact approach.
The 15 hour course with flexible deadlines is free to take (with a fee payable if you require a certificate) and includes experiences from the other CARIAA projects, including DECCMA.
CARIAA releases a series of “novel insights” into climate change, migration, and gender and social equity
Marking the end of the Collaborative Adaptation Initiative in Africa and Asia (CARIAA), IDRC has released a series of “novel insights”. These briefs capitalise on thematic learnings across the four CARIAA consortia that have been investigating adaptation in different hotspots – DECCMA in deltas, ASSAR and PRISE in semi-arid regions and economies, and HiAWARE in glacier-fed river basins. The novel insights synthesise findings on migration, gender and social equity, effective adaptation, the impact of a 1.5C increase in global temperature on the different hotspots, and research for impact.
DECCMA issues new infographic on gendered migration patterns and effects in the Indian Bengal delta
The DECCMA India team has just released a new infographic “Gendered migration patterns and effects in the Indian Bengal delta“. The infographic is based on household surveys in migrant-sending areas and migrant surveys in migrant-receiving areas and summarises where men and women migrate to, why, and with what effect.
