Bangladesh was the country most badly affected. Read this newspaper report. Bangladesh stretches across the world’s largest delta, where two of Asia’s great rivers meet. The people of Bangladesh live with the risk of flooding. Summer is always wet, because it is the monsoon season; in 2004 it was very wet. After almost non-stop rains in July and August, more than half of Bangladesh was already flooded. Then on 13 September 350 mm of rain fell in 24 hours in Dhaka, the worst rains for 50 years. Not only were monsoon rains heavy in Bangladesh, but the rivers were full of floodwater. This came from the very heavy monsoon rains in northern India and Nepal. Every year Bangladeshis become more worried about trees being cut down in the hills and mountains of India and Nepal. Deforestation increases run off into rivers. (i) As a result of the floods in 2004, at least 760 were killed and more than 35 million Bangladeshis were affected. River floods washed away countless homes, roads and stores of vital subsistence crops, especially rice. It was estimated that 8.5 million homes were destroyed. The government put the cost of repairs to roads, agriculture and industry at US$6bn. In the countryside where 75% of Bangladeshis live, the monsoon is normally welcomed. Houses are built on raised ground, sometimes on stilts. The river floods leave a new layer of rich silt which fertilises the padi (wet rice) fields. The many rivers and lakes are important sources of fish, which adds protein to the diet of rice farmers. But in 2004 flood waters were more than four metres above normal flood levels, surrounding homes, wiping out the rice crop and threatening diarrhoea, dysentery and other diseases spread by dirty water. What is the evidence that flooding in 2004 in Bangladesh was much worse than normal? .................................................................................................................................. .................................................................................................................................. ..............................................................................................................................[2] (ii) Where do people in Bangladesh live so as to avoid the normal monsoon floods? ..............................................................................................................................[1] © UCLES 2006 5014/01/O/N/06 www.xtremepapers.net For Examiner’s Use For Examiner’s Use 23 (d) Floods have both advantages and disadvantages for farmers in Bangladesh.
