Introduction

´╗┐Flooding: Bangladesh 2004 Bangladesh is a LEDC (Less Economically Developed Country in central Asia, it boarders with India(Figure. 1), with the most northern regions of Bangladesh being part of the Himalayas mountain range, home to the world largest on land mountain, Mount Everest. This case study is going to look at the causes and effects of the floods which hit Bangladesh in summer 2004 (June ? August) along with that the social, economic and environmental impacts. Where in Bangladesh? Figure. 1 All regions of Bangladesh were flooded in some way, but the area?s most affected by the monsoon floods were Northern, Rajshanhi and central region, Dhaka.

With relief efforts still going on 3 months after the floods had gone, people still needed help to rehabilitate their lives in December. Over 100,000 people contracted diarrhoea; this again posed a threat to others as it would have contaminated the flood water even more, putting others at risk of catching the contagious infection. More than 800 people died in the Bangladesh floods by mid- September by drowning, disease, snake bites or houses collapsing. The preparation by the Bangladeshi government was poor as they could learned from past major floods (floods in 1998) on how to cope with the swells of water and changed their management strategies towards how they carry out relief work better. Also to secure waste facilities to reduce the risk of diseases and infection caught in contaminated waters to reduce the amount of deaths and to relive the strain on hospital workers. Along with that, the government need to invest money into flood prevention systems as it will save a lot of money in the long term. ...read more.
