Natural disasters The extremely severe tropical cyclone, named Cyclone Sidr, was the major natural disaster in this decade. Sidr formed in the central Bay of Bengal, and quickly turned into a Category-5 equivalent tropical cyclone on the Saffir-Simpson Scale. The storm eventually made landfall in Bangladesh on 15 November 2007, causing large-scale evacuations. At least 3,447 deaths have been blamed on the storm,. Save the Children estimated the number of deaths associated with the cyclone to be between 3,100 and 10,000, while the Red Crescent Society reported on 18 November that the number of deaths could be up to 15,000. International groups pledged US$95 million to repair the damage, which was estimated at $1.7 billion (2007 USD). Besides there have been multiple flood events throughout the decade. In late summer 2002, heavy monsoon rains led to massive flooding in eastern India, Nepal, and Bangladesh, killing over 500 people and leaving millions homeless. There were estimated 3.5 million victims of flooding in 30 out of 64 districts. In 2004, monsoon flood intensified from April to July leading to the destruction of the rice crop in the northern region just before it was harvested. Water persisted in these regions for 3 to 4 weeks whilst gradually draining southwards, severely flooding most of Central Bangladesh. The high water level and widest extent of the flood was reached on 24 July affecting 39 out of 64 districts and 36 million people. In 2007 a series of floods impacted South Asia including Bangladesh. During this flood an estimated 7.5 million people had fled their homes, more than 50,000 people had diarrhoea or other waterborne diseases and more than 400,000 people took temporary shelters.
