The Dynamic Duo - Modeling Coupled Earth and Human Systems: CSDMS 2017 Annual Meeting

Robert Nicholls, Attila Lazar, and Frances Dunn attended the annual meeting of CSDMS (Community Surface Dynamics Modeling Systems) in Boulder, Colorado, USA, at foot of the Rocky Mountains, 25-27 May 2017. This is a model-based community of scientists that have met annually since 2002 with the goal of advancing modelling by sharing, standardising, and coupling (see CDSMS website where a large number of open source models are available for download). The three day conference comprised presentations, poster sessions, workshops, and participatory sessions, which cover the range of subjects relevant to surface dynamics modeling. This year's theme was particularly relevant to the DECCMA project as the conference focused on coupling physical environment and human systems within models. Establishing the link between human and physical modellers has been an ongoing effort of CSDMS. The ‘Human dimension’ (formally known as the ‘Anthropocene’) research focus group was established a few years ago, but this conference brought social scientists and human system modellers together in large numbers.

What do we know about adaptation in the Volta, Mahanadi and Ganges-Brahmaputra-Meghna deltas?

Deltas are viewed as climate change hotspots. Hotspots are where high exposure to climate-related hazards coincides with large numbers of vulnerable people-globally 500 million reside in deltas.

Conference setting

Gender and Climate Change addressed for the first time at the XV National Conference on Women’s Studies, India

Gender and women’s rights are being increasingly addressed worldwide through movements and media, which are inspired by the realm of women’s studies. While this change is a welcome one, it also has to be kept in mind that the challenges and disparities still remain and a long way has to be traversed. At this juxtaposition of phenomenon, the Indian Association for Women’s Studies (IAWS) organised the XV National Conference on Women’s Studies at the University of Madras, Chennai from 22 – 25 January 2017 with a theme “Women in a Changing World: Restructured inequalities, counter currents and Sites of Resistance”.

Land disappearing beneath your feet - environmental migration in the Sundarbans

Like all deltas, the islands in the Sundarbans are constantly being remoulded by environmental forces. Formation and reformation of islands results from the balance (or otherwise) between inflows of water and sediment load. When rainfall or snowmelt in the highlands is high, the greater erosive force of the river reduces the size of the islands; but when water in the river is reduced it encourages sedimentation and the growth of the islands. Sea level rise also plays a role in the dynamic environment.

Left-behind women, left-behind wives - The gendered impact of migration in the Mahanadi delta

Bina lives in a remote village situated on a spit of land at the crossing of the rivers Brahamani, Hansua and Kharasrota. Her husband is working in Delhi while she is looking after their two children, one boy and one girl. They live in a mud house, on the edge of the Brahamani. It is their third house, the first was lost in the river 15 years ago and the second house had to be evacuated three years ago for the same reason.

Motivations and challenges of integrating local peoples views into a deterministic model

From predicting traffic to budgeting monthly expenses, mental models inform everyday decisions by relating possible conditions (e.g. number of cars) to expected outputs (e.g. delay length). As with computational models, mental models are continuously updated as new information comes to light. Consequently, no two perceptions of the world are the same, shaped by individual experiences of interpersonal relationships, culture and the environment around us.

DECCMA report and take home messages from the TransRe conference

The TransRe conference (Connecting the Dots: Migration. Environment. Resilience, 29 – 30 September 2016, Bonn, Germany) was organised to mark the half-way point in the TransRe project: Building resilience through translocality. Climate change, migration and social resilience of rural communities in Thailand. Over 60 participants from various countries engaged in highly stimulating debates. A really interesting range of research on the links between climate change migration and resilience were presented from multiple perspectives. The range of presentations included talks on meta-theoretical considerations, empirical evidence, governance and policies, methodological approaches and linkages between migration and changes in socio-ecological systems. In the conference opening speech, Koko Warner, from the UN Climate Change secretariat (UNFCCC), highlighted the need to expand the discussion on migration, adaptation, environmental change, and social resilience beyond the confines of academia given the wider relevance of these topics.

5th DECCMA consotium meeting in Ffort Raichak near Kolkata, India

Before travelling to India for the 5th DECCMA consortium meeting I was constantly checking the weather forecast for Kolkata. Being one of the DECCMA northern team members and never having been in India before the idea of 35oC and heavy rain made me feel a bit uncomfortable. However on our way from the airport to our 70 km away conference venue Ffort Raichak nobody was thinking about rain (there was none) nor temperature. All that counted was hoping that the “mariokart – style” bus driver would deliver us at the hotel in one piece (which he did).

Migration, resettlement, river erosion and cyclones; WP 3 Fieldwork in Bangladesh – May 2016

Of all the countries in the world, Bangladesh is one of the most vulnerable to the adverse effects of climate change. The regular and severe environmental hazards that already batter the country – tropical cyclones, river erosion, flood, landslides and drought – are all projected to increase in intensity and frequency as a result of global environmental change. Fieldwork conducted in the Lakshmipur district, southeast of Dhaka, enabled Northern and Bangladesh WP 3 members to observe first-hand how the effects of cyclones such as Roanu (heavy rain, strong winds and storm surge) together with the impact of Meghna river erosion affect the daily lives and livelihoods of inhabitants of Lakhipur and Ramgoti. The WP3 team in the field consisted of Dr Anwara Begum (BIDS), Mr Rashed Bhuiyan and Mr Mahmudol Hasan Rocky (RMRRU), and Dr Ricardo Safra de Campos (University of Exeter), with logistical support provided by BUET.

An integrated shrimp fish gher in GBM Delta

Integrated Shrimp Aquaculture for Climate change Adaptation

Shrimp aquaculture started in GBM delta during 1980s and mainly within coastal polders. It expanded rapidly where salinity was suitable. However, there was much concern on environmental and social grounds due to mal-practice of shrimp culture and diseases. In course of time, shrimp culture practice and areas of shrimp culture changed and mix culture took hold at many places. Integrated or mix farming with less environmental and social conflicts appears to have great potential as an adaption option to climate change in the coastal zone. Recently, a field survey has been conducted to learn more about this adaption option and appears to hold great promises.

Drones over the delta: Monitoring coastal protection structures along the shoreline of Ghana’s Volta delta using an Unmanned Aerial Vehicle (UAV)

Coastal erosion in the Keta district of the Ghana’s Volta delta is causing increasing problems by destroying property and infrastructure and displacing people. With erosion rates of up to 8 metres per year, proactive efforts are required to manage these impacts. Within the Keta Sea Defence Project (KSDP) various erosion control measures have been employed. These include hard engineering, such as groynes and revetments, and soft engineering, such as beach nourishment.

Migration: A complex Phenomena which defies simplification

Climate change, poverty and the nexus of socio-environmental drivers that drive or influence migration has emerged as a challenging issue to a wide group of researchers, policy makers and practitioners. Recognised in Paris and the Sustainable Development Goals alike (SDG 10, which sets out a target for "facilitating orderly, safe, regular and responsible migration and mobility of people including through the implementation of planned and well-managed migration policies) the issue has made it in where it had not in the MDGs 15 years earlier. However, when we drill deeper into these phenomena it becomes clear that unlike say poverty, social injustice or the disease burden, migration describes a social phenomenon to which it is disputed as to whether it poses a threat or an opportunity to society, or as seems more likely, sits as some complex connective tissue between the two.

A Tale of 2 Cities………..

2015 saw an acceleration of DECCMA with extensive work on the development of Household Surveys across four study deltas in India, Bangladesh and Ghana, looking at the component role climatic change might play in migration and adaptation. This work has been substantially supported by the outcomes of a sister project to DECCMA in the form of ESPA Deltas. Both of these projects were represented at the AGU December 2015 in San Francisco at a specific session relating to Delta research, called Sustainable Deltas: Multidisciplinary Analyses of Complex Systems II, Global Environmental Change (Primary Convener Irina Overeem CSDMS/INSTAAR on behalf of Belmont Deltas), with cross-referencing between the talks demonstrating a continuity of learning and development. The following were presented:

Projecting Fish Production Under Climate Change: A Comparative Analysis Across Three Vulnerable Deltas

Plymouth Marine Laboratory (PML) will be conducting a comparative analysis on the importance of fisheries for food security in the three deltas/regions: Volta (Ghana), Mahanadi (India) and Ganges-Brahmaputra-Meghna (Bangladesh) and how climate change could potentially influence marine ecosystems productivity. Deltas communities are strongly dependent on coastal fisheries including shallow wetlands and other semi-enclosed bodies of water. In these three countries fishery is a very important sector and contributes between 4-5% of Gross Domestic Product (GDP). Despite its importance for the local economy there are marked differences amongst countries, for example, the average per capita consumption (per year) of fish products varies with Ghana consuming the highest amount (25kg) followed by Bangladesh (14kg) and India (8.2kg). Delta communities are ranked amongst the poorest in the world and as a consequence potential impacts of global and regional climate change on the marine ecosystem productivity could have dramatic impacts on their economy and food security.

American Association of Geographers Meeting, Chicago April 2015

DECCMA team members Dr Andres Payo Garcia and Dr. Craig Hutton (Southampton University) attended and presented on ESPA Deltas at the recent American Association of Geographers in the city of Chicago, USA. The meeting session was organised by Cologne University in Germany and Ohio State University who have been collaborating on a project called Band-AID ( ) which is of direct relevance to DECCMA and operates a small number of case studies within the DECCMA study site in Bangladesh. The intention of the Band-AID project is to build a robust Belmont Challenge identified Earth System Analysis & Prediction System (ESAPS) for Bangladesh, to adapt/mitigate the detrimental hazards including sea-level rise. We will establish an advanced observation system based on contemporary space geodetic sensors to quantify (1) causes of sea-level rise and land motion and their robust vertical datum link, and (2) human interactions that governs coastal vulnerability in Bangladesh.
