Bangladesh is a poor country in Asia. In 2004, floods built up until 60% of Bangladesh was covered in water with 40% of the capital city covered. Most of the country is flat and the River Ganges and Brahmaputra flow through it. The flooding occurs every year, however is leaves a fertile soil that is good for farming. Flooding is a problem when it gets severe.
900mm of rain fell in July. This is the heaviest rainfall for 50 years and it was due to the monsoon. This meant that the soils became saturated so this increased surface run off into rivers.
Melting snow from the Himalayas increased the amount of discharge both of the rivers had.
Deforestation in the Himalayas due to increased population in Nepal (fuel and farmland).
Additional surface run off carries silt with it and deposits this in the river. This means the river can carry less water so more likely to overflow.
Climate change is causing glaciers in the himalayas to melt and therefore increasing the amount of surface run off going into the rivers.
750 people killed - children vulnerable due to drowning and snake bites
Houses were flooded - 30 million were made homeless
44 schools and many hospitals destroyed
People lost businesses and their jobs
Dhaka underwater - roads and bridges under water too. - 10, 000km destroyed
Crops and livestock destroyed - food supply and cash crops destroyed
River polluted with rubbish and dead bodies.
Families damaged by losses of family members
People living on streets or in emergency camps set up by NGOs
1 million+ people suffered from malnutrition
People reliant on food aid
Contaminated water - Dhaka: 100,000 cases of cholera
Rebuilding and clean up estimated at $3 billion
Loss of income
Families climbed onto roofs - so did snakes
Evacuation couldn't happen in all areas due to blocked up roads and no control from the government. This means that people couldn't get out which lead to deaths.
International aid - Oxfam gave food, shelter, medical care and rescue teams and boats.
Long Term Responses
Aid from goverments and NGOs was used to help rebuilding of homes
Houses built on stilts
Children taught how to swim
Communities aware of what to do when flooding occurs
Schools and medical centres built
Better flood warning systems
River channels dredged so more discharge able to be held in the river
