Desert in Bengal Delta‑Changes in Landscape, Changes in Livelihood: Can Diffusion and Adoption of Sustainable Adaptation Make a Difference?
Abstract
This study is aimed to assess the impacts of various climate induced events and the sustainability of adoption of coping and adaptive measures against these impacts. The study was conducted through participatory rural appraisal (PRA) and focus group discussion (FGD) in three sites of Kalapara Upazila (Sub-district), located along the Bay of Bengal in Southwest Bangladesh. Finding suggests that although flooding, cyclones, storm surges, and seasonal droughts have different attributes, they have commonality in bringing severe salinity in soil, sub-soil water, and surface water bodies that severely affects the livelihood security of natural resource-dependent coastal population. Indigenous knowledge and diffusion of vernacular technologies have helped a large majority of people to adopt various coping and adaptation strategies against the salinity problem for long. However, in a changing nature of salinity (i.e. a discrete isolated event has been turning to a perpetual event), which is resulting from climate change induced sea level rise (CC-SLR), most of their adopted coping and adaptation measures have failed to address their livelihood security on a sustained basis. To bolster their efforts toward adoption of adaptation strategies for sustainable livelihood, a range of avenues for interventions are identified.
