“Life is cruel here” Stories from forced migrants in Chittagong, Bangladesh, has now been published. The story is based on experiences of migrants told to the DECCMA Bangladesh research team as they were undertaking surveys of migrants in receiving areas.
Delta
What does a 1.5â°C 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 1.5â°C, 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 1.5â°C, 2â°C or 3â°C.
Following the historic Paris Agreement, 1.5 â°C has become a hot topic. The Paris Agreement commits developed and developing countries to global temperature increase to 2â°C, with the aspiration to limit to 1.5â°C. These numbers are widely believed to be critical thresholds beyond which significant changes in the natural environment would be experienced (known as planetary boundaries).

The issue of 1.5â°C 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 1.5â°C increase informs the âambition mechanismâ, 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 1.5â°C, we have used our customised integrated assessment model âthe Delta Dynamic Integrated Emulator Model â 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 0.7â°C. 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 1.5â°C. 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 1.5â°C increase and a 2â°C increase are indistinguishable largely due to the year on year variability that is already characteristic of deltas.
If the temperature increase reaches 3â°C, some of consequences more than double. The area flooded under 3â°C is more than 2.5 times that under 1.5â°C 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 â 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.
FAOâs 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.
show more
Lead of the migration work in Ghana, Dr Mumuni Abu, was invited to share DECCMAâs 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.

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’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.

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 âResearch on Disaster Prevention / Mitigation measures against Flood and Storm Surges in Bangladeshâ (SATREPS).
show more
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:
- Evolution of flood management policy and planning
- Evaluating resilience against flood disaster
- Learning from experience of NGOs in disaster management
- Review of measures for river flood management in Bangladesh
- 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.

Migration and adaptation: a case study from the Khulna-Jessore region
by Nazia Bushra, Research Assistant, Refugee and Migratory Movement Research Unit (RMMRU)
Khulna stands on the banks of the Rupsha and the Bhairab rivers, located in southwest Bangladesh, and it is the geographical mid-point between the ports of Jessore and Mongla. It is also the second largest seaport of the country.
In the coming years, the Khulna-Jessore regions are going to become increasingly vulnerable to the effects of climate change. Khulna is already prone to salinity intrusion and cyclones. Less fresh water now flows in the adjacent rivers and saltwater intrudes here from the Bay of Bengal. Also, the local shrimp aquaculture is affected by viruses and other harmful factors related to high salinity and the increase in water temperature.
show more
In the case of Jessore, the increased salinity, floods, and storms are all major drivers of human migration from this locale. In order to obtain accurate data on the magnitude of migration and adaptation status of these two regions, we conducted a household survey of the 8 mouzas of these two cities. During the household listing survey, we found that people are suffering here from livelihood crises and related economic challenges. A large portion of household members that we interviewed were educated, which might explain their tendency to migrate to other regions and abroad. However, some of them are adapting to the present situation by adopting new technologies. They cultivate saline-resistant rice varieties (e.g. IRRI-11, 23, 54) and vegetables (e.g. water-melon, pumpkin etc.) but most cultivation takes place only during the rainy season; in dry season they usually buy vegetables and crops from neighbouring areas.
In Khulna, some of the most challenging environmental situations are found in Amurkata and Paikgachha. The communication system, mobile networks and food accessibility are all hampered by logistical issues. Environmental problems such as salinity of drinking water, low diversity of crop varieties, waterlogging, and cyclone-induced tidal surges are pervasive in this area. Local NGOâs such as ASA, BRAC, JJS, NOBOJUG etc. are trying to provide fresh water to these areas and the government is also constructing some cyclone shelters. Because of the prevalence of cyclones, most of the houses are made up of mud and conventional golpata, and electricity is relatively scarce among these types of dwellings.
In Jessore, Bahadurpur village has two areas named Mathpara and Hotatpara which received many migrants from neighbouring areas during times of flood and other natural disasters. These displaced persons are economically vulnerable as they try to adapt to life here. They face unemployment, job insecurity and the lack of other basic facilities, such as a scarcity of clean water. The unhygienic sanitation conditions, combined with the other difficulties, have led to a high incidence of diseases.

The challenges of living with climate change in Noakhali and Laxmipur Districts
by Aysha Akter Akhi
It is a nice opportunity to work with RMMRU on the DECCMA project. For the purpose of completing this work, I got a chance to visit the Noakhali-Laxmipur region of Bangladesh. This visit enabled me to talk with the people of this remote area. I visited 7 Mouzas in Noakhali and Laxmipur district. The people of these areas are mostly affected by the consequences of climate change. Cyclone, flood, river erosion, scarcity of rain, heavy rainfalls are frequent in these areas. Among 7 Mouzas, I found that the Char Elahi Mouza of Companigonj of Noakhali district is the most vulnerable.
I went to Char Lengta of Char Elahi which is very close to the Meghna River. People who live on the bank of the river are at serious risk. Because of environmental factors like river erosion, many people have lost their houses, lands, and other belongings. They live in bamboo or tin-metaljhupri houses.

Economic difficulties mean that attaining regular meals is difficult for many people here. Some have responded to these difficulties by becoming migrants. Many are living in the homes of friends and family places, while some have taken shelter in Mosques and Primary Schools. The usual occupations for many of these people are fishing and cultivation, but at present they have no land to cultivate and there has been a drastic reduction in fish populations in the river. Many are not provided with basic human rights, like food and shelter.
For these reasons, people in Char Elahi have a lot of complains against their local representative. They claim that not a single person is ready to hear them or even to talk with them, and that help is far away. When I went to talk with those people, they thought that perhaps I would do some help or provide financial aid to them. Alas! there was nothing I could to for them except listen to their sorrows and sufferings.  I observed their lives and their needs very closely. They fight with nature early and late with great courage.

The lives of littoral people in Rehania
by Tamanna Nazneen
Rehania is a coastal village in Bangladesh on Hatiya Island, Noakhali. Cyclone, coastal flood and water salinity are some of the common natural hazards in Rehania. Recently, a research survey led by DECCMA (Deltas, Vulnerability and Climate Change: Migration and Adaptation), under RMMRU (Refugee and Migratory Movements Research Unit), has been held in this area. For this reason, I had the great opportunity of going to Hatiya and observing the lifestyle of the people in the Rehania village.
Most of the people of Rehania are the victim of natural hazards like floods, river erosion and cyclones. They migrated here from other coastal areas of Noakhali, Lakshmipur, Bhola and Sandhwip (Chittagong). They lost everything from river erosion and cyclones. The Government re-housed them on the two sides of river dam and gave them a small amount of land per family but it was inadequate.

There is a lack of effective livelihoods. At first, people earned their livelihood by farming and fishing but the farming lands in the surrounding areas are also affected by flooding, more than three times per year. Flood water is very saline here and as a result the farming land has become saline. During the dry season, a white layer of salt is visible on the land so farming becomes difficult.  Farmers grow Aaush paddy (a variation of paddy which grows in the summer and is harvested during the monsoon), chilli and ground nut but in most cases crops are destroyed because of flood and water salinity.
Due to global warming, sea levels are rising and salinity of the sea is entering up stream through rivers and feeder canals resulting in most of the farmers changing their livelihood. In recent years, they earn their livelihood by fishing and doing other jobs through migration.  Seasonal migration is an important livelihood strategy to these families. More than 70% of their incomes are derived from outside the village. Most of the seasonal migrants work in brickfields in Chittagong under a contract and after a working season return home with their wages, of which a significant amount is spent buying fishing nets and boats (in share). They also send some remittances for their family. Fishing is their monsoon season job and during dry season they always migrate for other work (in brickfields).
In Rehania, many women are self-employed doing animal husbandry. They lease cattle and tend. In exchange, they get some money and can sell milk after giving a specific portion to the cattle owner. When we went to Rehania village for the survey and wanted to interview them, at first, they thought we were government workers who had come to them for reporting about their life conditions, so that they could get their desired governmental help for materials for building more sustainable houses and a sanitary latrine. They were eager to take effective training about cultivation methods of flood prone areas and also wanted a subsidy for agriculture, saline water tolerant crop seeds and fishing materials.
When they came to know about our research and its aim, they became tamed, but most of them spread their helping hand and cordially responded to our questionnaire. Though their life is afflicted with lots of pain, they never give up their smiles and hospitality. Whenever we went to any respondentâs house, they treated us with green coconuts, ground nuts, mangoes and whatever they had. We were amazed with their cordial behaviour and realised again the hospitable nature of the Bangladeshi people.
We were also amazed with the children of Rehania. They were very interesting and curiously stared at us with our tablets and questionnaire papers. They wanted to follow us around but we insisted that they did not and instead go to their school. Whenever it was possible we offered them chocolates, biscuits and juice to have with us. They also gave us red hibiscus flowers. This flower is available in every house and roadside.
Natural disasters are a part of their life. They always have to face it and struggle against it just like other littoral people. Naturally, they are brave and have adaptational capacities in such a hostile environment. They know how to keep their house safe from cyclones by planting banana and coconut trees around their houses. For a better livelihood they migrate to other places and try to send remittances. They are optimistic about their life. They just want some help from the government to make their livelihood more sustainable.  The days may be hard, but their hopes and aspirations are never tamed. The always-smiling face is the symbol of their life spirit.
