Bangladesh 31 Mar 2015 08:27
Bangladesh is a country of rivers and waterways on which large swaths of its population live. River bank erosion and flooding are common and continuous process due to global warming and rising sea levels. This continuous natural hazard is destroying homes and livelihoods and turning millions of Bangladeshis into homeless climate refugees.
The factors controlling river and stream formation are complex and interrelated. These factors include the amount and rate of water supply from rain and upstream activity, sediment deposited into the stream systems, catchment geology, and the type and extent of vegetation in the catchment. As these factors change over time, river systems respond by altering their shape and course. Unpredictable weather patterns also make flooding a common problem as the course of the rivers shift.
As a result of riverbank erosion and flooding, millions of people are losing their homes and fertile land every year. Most people who lose their homes or land become climate refugees, often pouring into the country’s overpopulated cities penniless and looking for new opportunities. However, due to overpopulation, migrating climate refugees often arrive in the cities only to find themselves scrounging for food, work and accommodation. Thus, Bangladesh’s most vulnerable citizens are losing their battle against nature and are only made poorer and more desperate.
