    Deltas, vulnerability and climate change ; migration and adaptation (DECCMA) CARIAA consortium final technical report 2018
    (CARIAA, 2018-12) Nicholls, Robert J.; Kebede, Abiy; Hutton, Craig W.; Dunn, Frances E.; Vincent, Katharine; Rahman, Munsur; Salehin, Mashfiqus; Rahman, Anisur; Ghosh, Tuhin; Banerjee, Sumana; Codjoe, Samuel N.A.; Appeaning-Addo, Kwasi; Owusu, Gertrude; DECCMA Consortium
    This report summarises the main outcomes and learning from management and delivery of the nearly 5-year “DEltas, vulnerability and Climate Change; Migration and Adaptation” (DECCMA) project within the “Collaborative Adaptation Research Initiative in Africa and Asia” (CARIAA) programme. DECCMA considered climate change and deltas with a strong focus on adaptation and migration within deltas, including migration as an adaptation. It was committed to being gender-sensitive in research approach, data collection, and analysis. Globally deltas and their environs house 500 million (or 7 percent of global population) people on one percent of the land area, with a concentration of populated deltas at mid and low latitudes. Deltas are highly dynamic biophysically. This includes a high vulnerability to sea-level rise and climate change, and also subsidence (deltas sink), exacerbating global changes in sea level. Deltas are also socially dynamic, with changing land use, economies and strong trends of migration that have potential to be modified under future environmental and climate change.

    Climate change, migration and adaptation in deltas Key findings from the DECCMA projet
    (Deltas, vulnerability & Climate Change: Migration & Adaptation (DECCMA), 2019) Ayamga, Jennifer; Das, Shouvik; Banerjee, Sumana; Nicholls, Robert; Hutton, Craig; Vincent, Katharine; Rahman, Munsur; Salehin, Mashfiqus; Rahman, Anisur; Ghosh, Tuhin; Codjoe, Samuel N.A.; Appeaning-Addo, Kwasi; Owusu, Gertrude; DECCMA Consortium
    Deltas are home to 500 million people worldwide and known as a climate hange “hotspot” – a place where high exposure to climate stresses coincides with high levels of vulnerability. DECCMA has been undertaking research on climate and environmental change, migration and adaptation in three delta ystems: the transboundary Ganges-Brahmaputra-Meghna megadelta (comprising the Indian Bengal delta, as well as the bulk in Bangladesh), the Mahanadi delta in India, and the Volta in Ghana.

    A framework for the design and evaluation of adaptation pathways in large river deltas
    (DECCMA, 2016-03) Chapman, Alex; Tompkins, Emma L.; Vincent, Katharine; Day, Sophie
    The pathways approach to adaptation has been applied to delta regions previously, but to a limited extent, Haasnoot et al. (2012), for instance, explore a theoretical delta case. Perhaps the most pertinent example is Kwakkel et al. (2015), who systematically evaluate adaptation pathways in the Rhine Delta. They highlight the strong decision-support potential of systematic multi-objective evaluation of flexible pathways (i.e. pathways which can be switched between as the system evolves through time). Yet their policy set might be regarded as restricted when compared with the scope of the DECCMA project; they do not model household decision-making or diverse livelihoods, and consider primarily hard, hydraulic adaptation interventions. Most importantly they do not consider migration and relocation choices, which are now becoming pertinent in delta regions. The systematic evaluation of cross-sectoral adaptation pathways at the large-system scale seems largely unexplored, and worthy of consideration for methodological learning, and because of its potential role in enabling climate-resilient development.

    Barriers and enablers of climate change adaptation in semi-arid Ghana
    (ASSART, 2016-03) Adaptation at Scale in Semi-Arid Regions
    This briefing note summarises the key findings from the Regional Diagnostic Study (RDS) recently conducted in Ghana, as part of the ASSAR project. The RDS aimed to: - Develop a systematic understanding of existing knowledge of climate change trends, impacts, vulnerabilities, and adaptation strategies. - Identify the key barriers and enablers of effective adaptation in semi-arid regions. - Identify gaps in research, policy and practice related to climate change adaptation. - Provide a foundation for developing an integrated regional research program (RRP) on climate change vulnerability and adaptation.

    Migration in the Ganga-Brahmaputara-Meghna Delta : a review of the literature
    (DECCMA Working Paper, 2015-08) Bhuiyan, Mohammad Rashed Alam; Siddiqui, Tasneem
    This paper aims to examine the findings from previous studies and household surveys on migration in Bangladesh with an emphasis on the Ganga-Brahmaputara-Meghna (GBM) basin areas.

    Systematic review of research on climate change adaptation policy and practice in Africa and South Asia deltas
    (Springer, 2014-10) Lwasa, Shuaib
    This paper synthesizes selected literature on adaptation policy and practice in river deltas located in Africa and South Asia. A systematic review methodology was used to scan online knowledge portals for published papers and also unpublished government documents. The review characterizes the state of adaptation policy in African and South Asian deltas, and identifies future research priorities targeting climate change adaptation in large delta regions. Policy strengths and gaps are assessed in the context of adaptation plans, revealing adaptation policy gaps regarding knowledge advancement, scaling up actions, and the move from incremental adaptation to transformational adaptation.
