Climate Change in Bangladesh:
Bangladesh is home to one the world’s largest delta systems. Two-thirds of the country is less than five metres above sea level. It is vulnerable to short-term climate shocks such as cyclones. Severe cyclones occur on average once every three years, creating storm surges sometimes in excess of ten metres high. In 2006, Cyclone Sidr caused £900 million of damage (2.7% of Gross Domestic Product (GDP) in 2007).
Bangladesh is also at risk from long-term climate change, particularly sea level rise. The country is already highly susceptible to flooding. It is not uncommon for over a quarter of the country to be submerged during the monsoon season. Global temperatures are rising, extreme floods are becoming more common.
The effects are significant and widespread. Homes and infrastructure such as roads are damaged, people displaced and agricultural and industrial production reduced (notably rice and livestock). The majority of the country’s 50 million extreme poor are particularly vulnerable, since many live on marginal land such as river islands or along the coast.
