• The country has a large population of 125million. It is one of the most densely populated countries in the world
• Experiences floods/tropical storms every year • The Ganges, Meghna and Brahmaputra all had their peak flows at the same time • Sea level increasing 7mm per year, decreasing gradient of the river, which in turns slows the river, increasing flooding |

Impacts
|
• Flood waters used to:
• Replenish ground water reserves • Provide nutrient rich sediment for vegetable production in the dry season • Provide a resource for aqua-culture. Fish supply 75% of dietary protein and over 10% of annual export earnings • Impacts of the flood are more catastrophic than the flood itself – spreads disease • Building costs and maintenance costs – too high for Bangladesh to afford |
