    Building resilience in African hotspots : learning from collaborative research
    (Springer, Cham, 2020-12-15) Czunyi, Sarah; Currie-Alder, Bruce
    Based on collaborative research conducted across 15 countries in Africa and South Asia, the chapter addresses three questions: 1) what is the difference between 1.5 and 2 degrees of global warming? Many parts of Africa, especially semi-arid lands, are warming faster than the global average with near-term consequences for agriculture, energy, and water; 2) how do gender, location and social difference shape who is vulnerable to climate change? Where someone lives also shapes their exposure, while the decision to migrate can diversify risk and alter household dynamics; 3) what is the effectiveness of adaptation from the lived experience of people and communities?

    Are large-scale collaborations worth it? : a longitudinal study of researchers’ perceptions over a 5 year program CARIAA-ASSAR
    (2021-09-01) Scodanibbio, Lucia; Kemp, Georgina Cundill
    The paper looks at experiences of participants in the large-scale, five-year collaborative research project, Adaptation at Scale in Semi-Arid Regions (ASSAR), midway and at the end of the project. It explores the benefits and limitations of transdisciplinary collaborations and the extent to which these can be outweighed through better programme design. The Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA) – ASSAR project supported the involvement of more than 250 researchers and practitioners. Figure 7 depicts the top five most cited challenges from each survey. The University of Cape Town was project lead, and housed the project management unit.

    Social vulnerability to environmental hazards in the Ganges-Brahmaputra-Meghna delta, India and Bangladesh
    (Elsevier Ltd., 2020-11-21) Das, Shouvik; Hazra, Sugata; Anisul, Haque; Rahman, Munsur; Nicholls, Robert J.; Ghosh, Amit; Ghosh, Tuhin; Salehin, Mashfiqus; de Campos, Ricardo Safra
    This detailed study provides the first analysis of social vulnerability across the entire coastal delta within Bangladesh and India. Three main conclusions emerge: 1) there is a cross-shore social vulnerability gradient throughout the delta with more vulnerable people living near the coast 2) non-agricultural development and economic expansion have reduced vulnerability significantly 3) shocks due to major cyclone landfall appear to have increased vulnerability in the impacted areas. Section 1 identifies the gaps in literature; Section 2 provides detailed administrative, demographic and socio-economic characteristics of the study area; Section 3 describes data and methods; Section 4-6 present results, discussion and conclusions.

    Using of landsat images for land use changes detection in the ecosystem : a case study of the Senegal river delta
    (2016) Toure, M. A.; Ndiaye, M. L.; Traore, V. B.; Faye, G.; Cisse, B.; Wade, C. T.
    The aim is to reconstruct the history of land use change in the Senegal River delta. Landsat images acquired in 1972, 1984 and 1988, 1999 and 2006, and 2014 are used to make the diachronic study. The Senegal River delta (study area) corresponds to the St. Louis, Louga, Podor, Dagana localities where the dynamic of land cover is very particular compared to national and most sub-region dynamics. The paper covers use of Landsat images to correct for land classifications, information differences, and accuracy of modelling. The study maps changes in order to locate types of changes, and measure their areal extent.

    Governance challenges in addressing climatic concerns in Coastal Asia and Africa
    (MDPI, 2019-04-10) Hossen, M. Anwar; Chowdhury, Arif; Hans, Asha; Tagoe, Cynthia Addoquaye; Allan, Andrew; Nelson, Winfred; Patel, Amrita; Mondal, M. Shahjahan; Salehin, Mashfiqus; Quaye, Ruth M.; Das, Shouvik
    Laws, policies and programs can fall short of addressing the needs of climate-affected people, especially in natural resource-dependent societies in Asia and Africa. This paper evaluates the effectiveness of existing policy documents affecting people living in one large delta (Ganges-Brahmaputra-Meghna in Bangladesh), two medium-sized deltas (Indian Bengal delta—part of the Ganges-Brahmaputra-Meghna and Mahanadi in India), and a small-sized delta (Volta in Ghana). National laws, policies and programs were assessed in the context of climate change adaptation through three lenses: human rights, natural resource management and disaster response.
