  1. LEDC CASE STUDYFlooding in Bangladesh

  2. Effects of the floods • Flood waters swept away and caused severe damage to railways, roads and bridges. This cut communications and made rescue operations difficult. • Water supplies were contaminated by dirty water and sewage and fresh water became scare. • Farmland was flooded and over 50% of crops in flooded areas were lost. • Many were killed. Deaths were not only due to being swept away by the flood waters but also secondary effects of flooding, such as disease spread in contaminated waters and the lack of food resulting in starvation in some cases.

  3. Effects of flooding cont. • Many people lost their homes and belongings. • There were great financial loses, such loss of income by shops and businesses which were unable to sell good or services and the costs incurred due to damaged infrastructure (roads, buildings etc.) • As an LEDC the results of flooding in Bangladesh were particular devastating not only due to its dense population but the lack of resources available to cope with such a disaster. Flood defence is a problem and the government cannot afford costly schemes.

  4. Responses to flooding Short Term Relief • Farmers provided with free seed from the government. Foreign aid is given (including money from the UK government) • Water Purification tablets were brought by money raised by the WHO (World Health Organisation) • Food aid was given (including foreign and national aid)

  5. Responses to flooding Long Term Flood Protection Measures • Flood protection shelters built (able to provide shelter in times of flood but have on other occasions been swept away by floods) • Flood embankments built along the river. Not always successful. Upstream dams proposed. These would hold back peak flow, but the costs of construction are very high. Reduce deforestation in headwater areas. • Making provision for emergency flood warning systems to give warnings and organise sufficient rescue and relief services (provision of emergency medical and food supplies).

  6. Reducing the risk of flooding • Bangladesh is an LEDC - it therefore does not have money to implement large schemes. • It is always going to be threatened with flooding, so the focus is on reducing the impact. • The Flood Action Plan is funded by the World Bank. It funds projects to monitor flood levels, and construct flood banks/artificial levees. • More sustainable ways of reducing the flooding include building coastal flood shelters on stilts and early warning systems.
