1USA is an MEDCIn the Americas TROPICAL REVOLVING STORMS are called hurricanesBangladesh is an LEDC …In Asia the TROPICAL REVOLVING STORMS are called cyclonesAre the impacts of storms different on MEDCs and LEDCs?
2The 6 metre storm surge in 1991 cyclone was catastrophic The 6 metre storm surge in 1991 cyclone was catastrophic * 240 km/hr wind speed * low pressure * especially high tide.* Due to the low elevation in many parts of Bangladesh, the storm surge was able to travel very far inland and cause much greater damage.
3In 1970, 300,000 people died in a cyclone 1988 cyclone Death toll over 2,000cyclone 1991 an estimated 140,000 deaths.Floods and cyclones continue to plague the country.Chittagong
4the April 1991 cyclone in the Chittagong area: Casualty figures in several of the villages near the coast were c. 70% of the population.In a belt at away from the coast the casualty rate 30-35%.
5The casualty rates for the different population categories were as follows: Children: 50%, Women: 25%. Elderly: 15% and Men: 10%
61991 cyclone left as many as 10 million homeless The storm caused an estimated 1.5 billion dollars in damage
7These people told us that if a big cyclone hit here, every one of them would be dead. Their homes were too flimsy to protect them.
8Farm crops destroyedFishing boats sunk and prawn stocks damaged.Aquaculture for prawns is a booming business. They are raised in artificial pools to which chemical feed and fungicide is added!
10Cyclone MitigationSatellites spot the cyclone developing –Weather forecasters broadcast warnings.
11Broadcasts are heard by someone in the village … most people don’t have radios. Saleha Begum holding a radio. Radios are used to warn people of flooding. It is one of the elements of the disaster preparedness programme (Oxfam)

Rescue kitThere are many steps that people can take that will leave them prepared for when a cyclone hits. Everyone should develop a family plan, create a disaster kit, have a place to go, and secure your home.
13Try to get the warning out to people in remoter villages.
14In 1992, the OISCA Mangrove Planting Project started In 1992, the OISCA Mangrove Planting Project started. It was a difficult task - a path of trials and errorsThe mangrove trees break the force of the winds and the waves and so protect inland areas. They also trap soil and help to build the land out to sea giving protection.
15A cyclone wall serves as a protection from a storm surge, as well as a quick evacuation route in a cyclone. There is a need for community and government contribution towards the costs.
16Cyclone Shelters Ever since the 1991 cyclone catastrophe, numerous cyclone shelters have been built to provide a safe have for local people..
17These buildings are built at a height of 7 meters above ground and are made to withstand a potential storm surge.
19After the 1991 cyclone agencies constructed some of cyclone Shelters After the 1991 cyclone agencies constructed some of cyclone Shelters. The total quantity of cyclone shelter in the coastal area is now more than 1800, which are less than the need. Each can accommodate 1000 people.In normal weatherr they can be used as school rooms. They can also help to educate Muslim women. Disaster Preparedness Education is important.
20The local cyclone shelter The local cyclone shelter. The only thing likely to be left standing in a big cyclone. Oxfam helps build them. The only problem is, 15,000 villagers live here and the shelter only takes 400.
