Climate change has been heralded as one of the greatest threats of our time by scientists and world leaders. The impacts of this have devastating consequences to people. One of its main impacts is increased flooding, which by 2060 will affect more than a billion of the world’s population. Its effects mean “flooding on major rivers is expected to become more likely, and coastal communities will be threatened by rising sea levels,” (Moore, 2016). In one study by the University of Nottingham, the existing climate, emissions and socioeconomic scenario predicted
that the current 100-year flood would occur at least twice as frequently across 40% of the globe and approximately 450 million flood-prone people and 430,000 km of flood-prone cropland would be exposed to a doubling of flood frequency by 2050. With these changing conditions come devastating losses to communities of some of the world’s
most poorest and vulnerable countries, including Bangladesh. Disruption to natural cycles of rainfall and snowpack on the Tibetan, Plateau which feed into Bangladesh’s major rivers, increases flooding, saltwater intrusion and storm surges on the coastal belt; whilst also creating excess rain during the monsoon season, and inducing a shortage of it during the winter drought.
