“…Bangladesh is chosen because this country, including its fisheries sector, is considered a hot spot of societal vulnerability to climate change (IPCC 2007;Yu et al 2010;Maplecroft 2011). The marine fisheries sector in Bangladesh supports livelihoods of over half a million fishers and their household members (DoF 2012).…”

Globally, fisheries support livelihoods of over half a billion people who are exposed to multiple climatic stresses and shocks that affect their capacity to subsist. Yet, only limited research exists on the vulnerability of fisherybased livelihood systems to climate change. We assess the vulnerability of fishery-based livelihoods to the impacts of climate variability and change in two coastal fishing communities in Bangladesh. We use a composite index approach to calculate livelihood vulnerability and qualitative methods to understand how exposure, sensitivity, and adaptive capacity measured by sub-indices produce vulnerability. Our results suggest that exposure to floods and cyclones, sensitivity (such as dependence on small-scale marine fisheries for livelihoods), and lack of adaptive capacity in terms of physical, natural, and financial capital and diverse livelihood strategies construe livelihood vulnerability in different ways depending on the context. The most exposed community is not necessarily the most sensitive or least able to adapt because livelihood vulnerability is a result of combined but unequal influences of biophysical and socio-economic characteristics of communities and households. But within a fishing community, where households are similarly exposed, higher sensitivity and lower adaptive capacity combine to create higher vulnerability. Initiatives to reduce livelihood vulnerability should be correspondingly multifaceted.

“…Even today, food shortages are a persistent problem in Bangladesh (Douglas 2009;Wassmann, Jagadish, and Sumfleth 2009). In this region, large amounts of productive land could be lost to sea-level rise, with 40-percent area losses projected in southern Bangladesh for a 65 cm rise by the 2080s (Yu et al 2010). Tropical cyclones already lead to substantial damage to agricultural production, particularly in the Bay of Bengal region, yet very few assessments of the effects of climate change on agriculture in the region include estimates of the likely effects of increased tropical cyclone intensity.…”

“…Yu et al (2010) conducted a comprehensive assessment of future crop performance and consequences of production losses for Bangladesh. Taking into account the impact of changes in temperature and precipitation, the uncertain benefits of CO2 fertilization, mean changes in floods and inundation, and rising sea levels, the authors estimate that climate change will cause a reduction of about 2-6.5 percent in annual rice production from 2005-50, depending on the scenario (World Bank 2010; Yu et al 2010). …”

“…In Bangladesh, yield reductions in rice and wheat due to coastal flooding vary from 0% when floods partly submerge the plants for a few days to 100% when floods submerge most of the plant for a period longer than 15 days no matter the stage of plant development (Yu et al 2010). Moreover, in the southern region of Bangladesh, large amounts of productive land could be affected by sealevel rise, with 40% area losses projected for a 65 cm rise by the 2080s (Yu et al 2010).…”

“…Moreover, in the southern region of Bangladesh, large amounts of productive land could be affected by sealevel rise, with 40% area losses projected for a 65 cm rise by the 2080s (Yu et al 2010). In combination with changes in temperature of about 2°C and slightly increasing precipitation in 2050 compared to preindustrial levels and the benefits of CO2 fertilization, mean changes in floods and inundation as well as rising sea levels might cause an approximately 80-million-ton cumulative reduction in rice production in 2005-2050, or about 3.9% annually (World Bank 2010a; Yu et al 2010). Another study in Bangladesh found that a projected 27 cm sea-level rise by 2050, combined with storm surges, could inundate an area 88% larger than the area inundated by current storm surges (World Bank 2010a).…”
