countries, with its people crammed into a delta of rivers that empties into the Bay of Bengal.

• Full name: People's Republic of Bangladesh • Population: 164.4 million (UN, 2010) • Capital and largest city: Dhaka • Area: 143,998 sq km (55,598 sq miles) • Major language: Bengali • Major religions: Islam, Hinduism • Life expectancy: 69 years (men), 70 years (women) (UN)

Why?

Causes of floodingHuman Physical (Natural)

Increasing population means deforestation in the foothills of the Himalayas.

80% of the land area is a floodplain

Deforestation has led to soil erosion which means the river channels get silted up and carry less water.

Bangladesh is very low lying and has a monsoon climate.

Weight of population is creating subsidence which makes the land more prone to flooding.

Two major rivers bring lots of water into Bangladesh. The Ganges and Brahmaputra.

Bangladesh is an LEDC and has little money to spend on flood protection as much gets spent of foreign debt.

In spring melting snow water from the Himalayas increases water levels.

What impact did the flooding have
