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.

The final workshop of this extension project took place last week at the Planning Commission in Dhaka. Chaired by Professor Shamsul Alam, Senior Secretary in the General Economic Division of the Planning Commission, the workshop provided the opportunity for researchers to present their evaluations of the effect of three interventions proposed under the Delta Plan 2100.

Research team members Professor Robert Nicholls and Dr Alex Chapman (University of Southampton) and Professors Md. Munsur Rahman, Mashfiqus Salehin and Anisul Haque (Institute of Water and Flood Management, Bangladesh University of Engineering and Technology) outlined the implications of three structural interventions under the Delta Plan 2100: ‘Green belt’ along the  coastal vulnerable area and sea walls along a selection of polders (sea-facing and a cluster in the south central part of the coast).

Professor Alam expressed his appreciation for the analysis and stated that it will allow more confidence about its application. DECCMA has furthered the evolving relationship with the Planning Commission. Professor Alam expressed his interest in DECCMA’s integrated assessment model to assess the impacts of cyclones on the coast, sediment management and water-logging.

Mainstreaming climate change into district plans and budgets in Ghana

by Prosper Adiku

DECCMA used a dissemination and validation workshop to also build capacity on mainstreaming climate change. The workshop was attended by district officials, traditional leaders and community representatives from nine districts in the Volta delta of Ghana.

Winfred Nelson of the National Development Planning Commission (NDPC) and the DECCMA governance team presented on how to factor climate change into issues into planning and budgeting processes during the preparation of the short-term (2-year) Medium Term Development Plans at the district and municipal assembly levels.

The ethos of the workshop was participatory, with the community participants and district officers sharing their perception of climate change impacts, before discussion turned to potential personal and collective responses at adaptation and mitigation.

With regards to mainstreaming, officials indicated that although climate change issues are not treated separately in planning and budgeting processes, the challenge arises with the integration process due to the low levels of awareness of climate change and perceived.  Mr Nelson highlighted the opportunities to secure extra-budgetary adaptation funding if climate change is effectively mainstreamed.

DECCMA Special Session on Science-Policy Dialogue at the 4th Gobeshona Conference

by Mashrekur Rahman

The venue for this year’s Gobeshona Annual Conference for Research on Climate Change in Bangladesh was the Independent University of Bangladesh (IUB). The fourth day of the conference was centered on science-policy dialogues. A special session on the fourth day at the conference was hosted by DECCMA (DEltas, vulnerability & Climate Change: Migration & Adaptation) Project, IWFM (Institute of Water and Flood Management), BUET (Bangladesh University of Engineering and Technology).

Professor Dr. Munsur Rahman presented his keynote presentation titled “Integrated Assessment in Deltas”, focusing on the Ecosystem Services for Poverty Alleviation (ESPA) Deltas and DECCMA projects – two major international collaborative research projects which have attempted to link science and policy by providing policy makers with the scientific data, tools and expertise. Dr. Munsur briefly laid out the various aims, components and outputs of the two projects and discussed how the projects have been instrumental in the formulation of the Bangladesh Delta Plan 2100 (BDP 2100).

Thereafter, a panel discussion was held; the panelists were Mr. Saiful Alam – ex- Technical Director of WARPO, Malik Fida A Khan – Deputy Executive Director, Operation of CEGIS (Center for Environmental and Geographic Information Services), Dr.

Md. Taibur Rahman – Project Manager, UNDP, Dr. Sultan Ahmed – Additional Secretary, Department of Environment (DoE). The panel session was chaired by Professor Dr. Shamsul Alam–Member (Senior Secretary), General Economics Division (GED), Bangladesh Planning Commission, Government of Bangladesh.

Mr. Saiful Alam discussed Water Resources Planning Organization (WARPO)’s past involvement and contributions in the two before mentioned projects and the technical know-how provided for BDP 2100. He also briefly discussed the modelling aspects of WARPO and the two projects.  Mr. Malik Fida A Khan appreciated the value of the projects in integrating science and policy in Bangladesh and then emphasized on the importance of mainstreaming of tools such as the Delta Dynamic Integrated Emulator Model to ensure maximum science-policy linkage. Professor Shamsul Alam particularly pointed out glaring data gaps on climate change issues in Bangladesh and mentioned that the ESPA Deltas and the DECCMA projects have contributed a lot in somewhat abridging those gaps. Dr. Taibur discussed about the nexus between the scientific community and policy makers. He accentuated the importance of not adopting a consultant based approach for long term delta planning and encouraged the policy makers, politicians and leaders to be more accepting of a science-backed approach in planning, ensuring sustainable development. Dr. Sultan highlighted on how coastal vulnerabilities of Bangladesh have been exacerbated by degrading ecosystem services. He then discussed several approaches to bridging gaps between the scientific community and policy makers.

After speeches from the panelists, the floor was opened to the audience for a lively discussion session. At the end of discussions, Professor Dr. Munsur thanked everyone and subsequently Professor Shamsul Alam drew an official end to the session.

“Climate change is triggering a migrant crisis in Vietnam” now published on The Conversation

by Alex Chapman, University of Southampton

DECCMA and ESPA Deltas researcher Dr Alex Chapman’s piece “Climate change is triggering a migrant crisis in Vietnam” has just been published on The Conversation UK. The article outlines how net out-migration of one million people from the delta – over double the national average – relates to a reduction in agricultural productivity and the effects of repeated exposure to cyclones that cause erosion of land and infrastructure.

Crucially, the article highlights that the creation of embankments, intended by the government to support in situ adaptation, actually often have the opposite effect. This is because in protecting the land, the embankments prevent “normal” flooding that replenishes soil nutrients and supports fishery-based livelihoods. Dr Chapman concludes by highlighting the importance of ensuring economic growth and adaptation supports all groups of the population to reduce a potential migrant crisis.


What does a 1.5⁰C increase in global temperature mean for deltas?

by Robert Nicholls

Deltas are a climate change hotspot, where the effects of climate change coincide with large numbers of people. Sea level rise is a major threat to deltas, bringing risks of flooding and erosion. As the world tries to limit the global temperature increase to 1.5⁰C, the DEltas, vulnerability and Climate Change: Migration and Adaptation (DECCMA) project has been looking at how deltas will be affected by increases in temperature of 1.5⁰C, 2⁰C or 3⁰C.

Following the historic Paris Agreement, 1.5 ⁰C has become a hot topic.  The Paris Agreement commits developed and developing countries to global temperature increase to 2⁰C, with the aspiration to limit to 1.5⁰C.  These numbers are widely believed to be critical thresholds beyond which significant changes in the natural environment would be experienced (known as planetary boundaries).

show more

The issue of 1.5⁰C has recently been high on the political agenda again, as the 23rd Conference of the Parties to the UNFCCC met in Bonn to discuss a framework for reporting climate action to monitor the commitments made under the agreement.  Knowing the implications of a 1.5⁰C increase informs the “ambition mechanism”, whereby stocktakes of progress are due to be taken every 5 years, with a view to then revising and updating mitigation and adaptation commitments.  Improvements in science play a key input to ensuring that these commitments remain ambitious and on target to limit the damaging effects of climate change.

Deltas are home to 500 million people worldwide, as well as being natural environments that generate livelihoods, income and essential ecosystem services.  DECCMA has been investigating the effects of climate change in four study sites across three deltas across Africa and Asia: the Ganges-Brahmaputra-Meghna (GBM) megadelta in Bangladesh and the Indian Bengal component in India; and the smaller deltas of Mahanadi in India and Volta in Ghana.

Given the interest in 1.5⁰C, we have used our customised integrated assessment model –the Delta Dynamic Integrated Emulator Model – to look at the likely changes in flooding (in terms of depth of flood and area affected) and the impacts on population in the GBM in Bangladesh under three different scales of temperature increase: 1.5°C, 2.0°C and 3.0°C.

If we continue with relatively high rates of greenhouse gas emissions, models show that a 1.5°C increase could occur from 2011 to 2033.  Rates of temperature increase have already been significant and rapid.  Observed changes in temperature over the 20th century showed an increase in 0.7⁰C.  In comparison, in the readjustment period since the last ice age global temperatures have only increased by between 4-7c over 5000 years.

Sea level rise of 5-14cm is associated with an increase in global temperature of 1.5⁰C.  This may not seem a lot, and it is particularly difficult to find a reference period because sea levels have varied significantly over the last 20,000 years, reflecting glacial periods and the readjustment of land masses.  But, as an indication, sea levels rose by less than 2mm over the 20th century, so the projected increase is over 20 times more than that.

Until 2040 the differences that are likely from a 1.5⁰C increase and a 2⁰C increase are indistinguishable largely due to the year on year variability that is already characteristic of deltas.

If the temperature increase reaches 3⁰C, some of consequences more than double.  The area flooded under 3⁰C is more than 2.5 times that under 1.5⁰C of such sea level rise, for example.  Those at greatest risk are in the central regions and northeast, where there are fewer polders to protect the land.

The good news is that there is still time to implement adaptation – if we act now.  Our team has investigated adaptation and found 93 documented examples in our study deltas spanning agriculture, water management and disaster risk reduction.  We are now in the process of developing an integrated assessment model that will give us insights into adaptation needs and options under various future scenarios.

DECCMA team participates in FAO Regional Meeting in Ghana

by Prosper Adiku

DECCMA was invited to make a presentation at the Food and Agriculture Organisation Regional Meeting held in Akosombo, Ghana from November 20-24, 2017; and hosted a field visit to the Volta delta.

FAO’s is committed to promoting rural agricultural development. Migration currently has a negative impact on agriculture by taking away economically-active adults, and so the intention is to make agriculture attractive.

Lead of the migration work in Ghana, Dr Mumuni Abu, was invited to share DECCMA’s findings on climate change and migration in the Volta delta, as well as to discuss how to leverage the opportunities presented by FAO in collaborating for further studies. He shared information on who migrants in the delta are, reasons for migrating, where the migrants go to, the duration of migration and the general perception of people about migration.

As part of the meeting programme, the DECCMA team hosted a visit to the Keta Municipality to learn about the interactions between climate change, migration and agriculture in the delta. The team interacted with officials of the District Assembly through presentations and discussions on climate change and agriculture-related issues in the Municipality and how these are impacting on the lives of the people. Officials from the planning department, Community development workers and the Information Services Department of the Assembly as well as DECCMA representatives were present during the interactions.

Gender and the Paris Agreement to the UNFCCC

By Katharine Vincent

Climate change does not affect men and women in the same way.  DECCMA recognises this and, through its research, aims to “deliver policy support to create the conditions for sustainable, gender-sensitive adaptation”.  How is DECCMA in line with the gender dimensions of climate change in international policy?

African Working Group on Gender and Climate Change side event at COP22 in Marrakech

The Paris Agreement is the latest legally-binding outcome under the United Nations Framework Convention on Climate Change (UNFCCC) – the global policy framework for addressing climate change.  The Paris Agreement has been in the spotlight again after the recent 23rd Meeting of the Conference of Parties (COP) to the UNFCCC, hosted by Fiji and held in Bonn.

show more

Despite the existing UNFCCC commitments to gender, the Paris Agreement is, outside of the Preamble, largely gender-blind.  A set of recent papers, commissioned by the African Working Group on Gender and Climate Change with the support of IDRC, show that the term “gender” features only three times throughout the whole Paris Agreement: once in the Preamble; once in Article 7 (adaptation-focused); and once in Article 1 (capacity building-focused).  Neither the articles on mitigation nor technology transfer mention gender.

By not explicitly referencing gender there is a risk that Parties do not apply a gender-responsive approach in implementing the Agreement, and thus existing gender inequalities are reinforced.   Women typically have less control over land, lower education levels, more restricted mobility (due to their home-based roles), and poorer levels of participation in decision-making compared to men.  However gender differences are context-specific and unpacking them is essential to develop gender-responsive adaptation.

Within its household survey DECCMA has been investigating the different ways that men and women adapt to climate change in the Ganges-Brahmaputra-Meghna, Indian Bengal, Mahanadi and Volta deltas.  It is our intention to use this to support gender-responsive adaptation, as outlined in Article 7 of the Paris Agreement.  Gender-responsive adaptations are better targeted to the different needs of men and women, and thus more effective and efficient.  We are also gender-sensitive in our capacity building attempts, and thus consistent with Article 11 of the Paris Agreement.

For a detailed gender analysis of the Paris Agreement, see this background paper produced by the African Working Group on Gender and Climate Change (with support of IDRC), and an accompanying gender-responsive implementation framework.

Holiday Experience in a Delta

by Sumana Banerjee

A holiday in Egypt during September this year was my first experience of a delta outside of DECCMA. Like any holiday it was supposed to be a break from work but quite on the contrary, I found myself asking questions, spotting differences and similarities, and doing some online research based on our DECCMA themes. That is why I am writing about the things I learnt on a holiday on our DECCMA blog.

1 The Giza Pyramid Complex, Egypt


Significance of the pyramid shape

For most tourists Egypt is synonymous with The Great Pyramid of Giza and I was no exception. The first glimpse of the man-made marvel from the ancient world made my heart skip a beat. It was an enthralling experience to witness the 3000 year old exemplary creation of man. There are plenty of theories about the construction of pyramids and their mysteries. The one fact which will be relevant here is the shape of the pyramid which represents the physical body emerging from the earth and ascended towards the light of the sun. This shape was thus considered sacred by ancient Egyptians. The Papyrus which was first used in ancient Egypt has a cross-section resembling the triangular face of the pyramid and we were told at a Papyrus Institute that this was also very important and sacred for the ancient Egyptians.

I couldn’t help but draw a connection between the triangular face of the pyramid, the triangular cross-section of the papyrus, and the triangular shape of a delta. I wondered if the delta being a lifeline of the region could have any role to play in influencing the triangular faces of the pyramids.

The River Nile

The very first sight of the River Nile at Cairo brought back geography lessons and hours of meticulous map pointing learnt way back in school. I was seeing the world’s longest river and Cairo was the apex of the Nile delta. Our itinerary entailed a 3-night river cruise along the Nile and I was excited to experience it. From our river cruise, we availed an optional speedboat ride to a Nubian village (about 8kms from Aswan) and that gave us an opportunity to soak our feet in the cool waters of the Nile. Before this ride, I knew that cataracts are for aging eyes but during this speedboat ride, our guide showed us the first cataract of the Nile. Cataracts are a mass of rocky formations in the riverbed jutting well above the water. Around this cataract the otherwise calm water was breaking and speeding naturally.

3 Cataract of the River Nile


The journey from Cairo to Alexandria took us about three hours by car. I noticed a stretch where there were many Brick kilns on both sides of the road. This was similar to what we see in the Indian Bengal Delta (IBD). I am not sure if the areas under brickfields in Egypt have undergone similar land transformations like in IBD but I wondered if conversion of deltaic lands into brickfields is a globally lucrative trend.

Flooding of the Nile

Since time immemorial Nile floods have quenched the thirst of the adjacent flood plains and added silt which has played a major role to support the Egyptian civilization. While no flooding led to drought followed by famine, severe flooding proved hazardous. It was the moderate flooding that the Egyptians looked forward to and this was the important part of their agricultural cycle as after the inundation season they sowed the seeds. Like any natural hazard, floods back then too had an effect on the economy – nature of flooding would have an impact on the quality of the harvest which will determine the tax to be paid. These administrative decisions were taken based on the exemplary mechanisms which were in place to predict the floods and thereby the quality of the harvest.

While scientists today have the flood-prediction models, the ancient Egyptians had the Nilometer. We saw one such Nilometer at the Temple of Kom Ombo, Aswan. It looked like a well to us till we were explained the elaborate architecture it housed. Upon looking down, we saw a flight of steps going down along the interior wall of the cylindrical well (see image 6). The water in it is the water of the Nile as the well is connected to the River. Being situated within the temple complex it was accessible only by the priests and kings who were responsible for assessing the water level in the Nilometer, making predictions based on how many steps were inundated, before finally deciding the tax. Like our scientists today who use previous years’ data to fit into models, the ancient Egyptians too kept a record of the previous years’ flood level by keeping marks on the walls. Unfortunately, now these Nilometers have been rendered defunct after the construction of the Aswan High Dam.

Developmental Project, Relocation, and Resettlement

Continuing the discussion on floods, the construction of the Aswan High Dam was an effort to introduce controlled flooding alongside providing water for irrigation and generating hydroelectricity. The economic benefits of this developmental project have mainly been in agricultural and electrical production. The construction of the dam involved resettlement of about 50,000 Egyptians and relocation of ancient monuments as the reservoir, Lake Nasser, created by the dam has flooded the valley. The famous Abu Simbel temple was relocated to higher grounds and I did not understand that the temple was not built at its present place till the guide told me. Not only did I feel overawed seeing the gigantic facade of the temple, I felt awe at the acumen involved in making this relocation happen.

The relocation of the temple was a great feat achieved by archaeologists but it might have been easier than the relocation of the Nubians as the temple did not have a lifestyle and tradition entwined with its original land. Upon some research I learnt that the construction of the Aswan High Dam is not the first time that the Nubians were moving from their lands. During the construction and heightening of the Aswan Low Dam, these people moved to higher lands but after the construction of the High Dam their villages were submerged under Lake Nasser. The Egyptian government put in years of study to make this a successful planned resettlement by trying to replicate as many features of the Nubian villages and also by providing electricity, road network, and irrigational facilities.[1] However all don’t seem happy (as informed by our guide) with the resettlement as this new place hampers the traditional Nubian way of life in many ways. Some online research would also throw light on the gaps in the resettlement process. These lessons might be beneficial for other governments making efforts in planned resettlement.

Migration then and now

The mystery behind the construction of pyramids still remains and there are countless theories trying to answer who constructed those and how they managed to achieve such a height of architectural precision in ancient times. One of the theories which I learnt was that the farmers from the plains came up to the Giza Plateau, when the Nile’s annual flood inundated their agricultural lands, to work as labourers in the construction of the Pyramids. Skilled architects and artists supervised these labour groups. My DECCMA-laced mind made a note of this example of seasonal migration from more than 3000 years ago which had an environmental factor (at the source) prompting it and an economic opportunity in the destination.

We got a very brief glimpse of migration today as our guide informed us that tourism being an important industry (tourism took a hit after the revolution in 2011 but is slowly picking up since 2016), people migrate to Cairo and Alexandria to work in the hotels, with tourist companies, or even as freelancing guides.

Sobek & Dakshin Rai

The Nile is famous for the Nile Crocodiles and the ancient Egyptians worshipped crocodile as god Sobek. The crocodile, although feared, was venerated and given a place in the temple of Kom Ombo, beside which there is now a Crocodile Museum showcasing the relevance of crocodiles in ancient Egypt with its large collection of mummified crocodiles. The worship was to please Sobek and pray so that he would not harm anyone. I saw this as an extension of the people of the Indian Sundarbans (West Bengal, India) worshipping the Royal Bengal Tiger in the form of Dakshin Rai (Lord of the South). Dakshin Rai is greatly feared in the delta but also worshipped along with Bon Bibi (guardian spirit of the forest) to not harm the people who venture into the forest for crab and honey collection. Separated by thousands of miles and years, the similarity in the belief of the two deltaic civilizations fascinated me.

Had DECCMA not happened to me, I would not have enjoyed my holiday the way I did – taking down notes on my phone, doing some online reading, drawing parallels across deltas, and wondering about things which would not have occurred to me otherwise. On learning about the tomb raiders I had a thought with which I shall end this post. The Great Pyramid of Giza and most of the tombs in the Valley of Kings have been wiped clean of artefacts and treasures which were believed to be there as was the ancient Egyptian custom to help the deceased continue onto the next life. I would like to believe that the tomb raiders who took these objects were in need of the money or wanted luxury and concentrated only on their immediate present which made them overlook the fact that their act was depriving hundreds of generations from witnessing a magnificent past of Egypt. Let us not be the tomb raiders for our future generations. We can do our little bits to not exploit the environment to meet our immediate needs and luxuries so that we do not deprive the future generations from witnessing a clean, healthy, and beautiful Earth.

DECCMA team discusses the forthcoming Bangladesh Delta Plan with the country’s Planning Commission

by Saiful Alam

The Bangladesh Delta Plan 2100 (BDP) takes an adaptive management approach and the strategy is based on eight hotspots in the country, one of which is covered within the DECCMA study area. In a meeting with Professor Shamsul Alam, Member Secretary of the Global Economic Department in the Planning commission, the DECCMA Bangladesh team highlighted how project findings can inform the plan.

DECCMA Bangladesh PI Professor Munsur Rahman presents Professor Shamsul of the Planning Commission with the latest project publications

DECCMA’s research is helping to build deeper understanding of the cross sectoral adaptation that will be required in future. Dr Michele Leone, who oversees DECCMA for the International Development Research Centre, outlined the inventory of adaptations and findings of autonomous adaptations in the household survey would inform the implementation the Bangladesh Delta Plan.

DECCMA Bangladesh Deputy PI, Dr Mashfiqus Salehin, added that the focus of DECCMA on migration has created significant insights who migrates, where, and with what consequences, and that the findings will be integrated into a model that will project changes in the delta in the context of climate change.

Referring to the linkages between adaptation and economic growth, Professor Alam said that the  Bangladesh Delta Plan makes significant progress compared to earlier water sector plans, by forging linkages between adaptation and economic development and growth in the country.  Professor Alam reiterated that for improved adaptation we need improved knowledge through multi-disciplinary research and innovations, and welcomed a Ganges Brahmaputra Meghna Delta Brief from the team, which summarises research findings to date.

Should we unpack “community-based adaptation”?

by Natalie Suckall                           

Despite many examples of successful community-based adaptation, DECCMA’s extensive household survey  across four deltas found very little evidence of collective action. Rather than being activities in addition to those of the household, instead community-level effects are only observed when there is an aggregation of household-based activities. Does this mean that we need to better interrogate “community-based adaptation”?

Natalie Suckall presents at the Development Studies Association 2017 annual conference

Interest in this topic emerged at the recent Development Studies Association 2017 annual conference, held at the University of Bradford. Five DECCMA researchers led a panel on sustainable deltas. From varied presentations on observed adaptation, adaptation governance, migration and remittances, and migration and adaptation, a common theme emerged – that of scale. In particular, how does DECCMA understand events that take place at the community level, as opposed to the household or national level?

show more

One of the issues faced by DECCMA researchers was that no examples of collective action and very few examples of community based adaptation were found during our initial literature review of observable adaptation in the deltas.

Although some adaptation interventions were characterised as CBA, their impact was often felt at the household level where different households within the community were affected in different ways. For example, polders (land reclaimed from the sea) in Bangladesh are often described as a community adaptation as they aim to protect entire communities from flooding as well as providing land for farmers and fishers. Sometimes communities are involved in their construction.

Whilst communities may be involved in the construction of polders, this does not mean that the benefits are equally spread.  Within each polder there exist multiple competing interests between government, farmers, pond owners, and the landless.  Larger and better off households are more likely to be successful farmers and fishers, with profit and yield unlikely to be distributed to the landless poor. What this really means is that each household is affected by the polder in a different way – and thus to talk of it as a community-based adaptation hides these differences.

Our survey of 6000 households in the four study sites provided an opportunity to search for examples of collective action. We found that in all four locations less than a quarter of households were involved in a cooperative group.  The highest membership was in the Indian Mahandi at 25%, whilst it was 14% in Ghana, 8% in Bangladesh, and only 6% in the Indian Bengal delta.

In light of these findings, DECCMA’s integrated assessment model considers only national and household-level adaptations. Our survey evidence shows that community-based adaptation is far less important than household level, and is captured by aggregating household-level benefits. Since findings show that community-based adaptation can have variable effects, we should perhaps interrogate it before promoting as an appropriation adaptation to climate change.
