2010 Pakistan floods


The 2010 floods in Pakistan began in late July, resulting from heavy monsoon rains in the Khyber Pakhtunkhwa, Sindh, Punjab and, Balochistan regions of Pakistan, which affected the Indus River basin. Approximately one-fifth of Pakistan's total land area was affected by the floods, with the Khyber Pakhtunkhwa province facing the brunt of the damage and casualties. Nationwide, there were 1,985 deaths. According to Pakistani government data, the floods directly affected about 20 million people, mostly by destruction of property, livelihood and infrastructure.
UN Secretary-General Ban Ki-moon had initially asked for US$460 million for emergency relief, noting that the flood was the worst disaster he had ever seen. Only 20% of the relief funds requested had been received by 15 August 2010. The U.N. had been concerned that aid was not arriving fast enough, and the World Health Organization reported that ten million people were forced to drink unsafe water. The Pakistani economy was harmed by extensive damage to infrastructure and crops. Damage to structures was estimated to exceed US$4 billion, and wheat crop damages were estimated to be over US$500 million. Total economic impact may have been as much as US$43 billion.

Causes

The floods were driven by rain. The rainfall anomaly map published by NASA showed unusually intense monsoon rains attributed to La Niña. On 21 June, the Pakistan Meteorological Department cautioned that urban and flash flooding could occur from July to September in the north parts of the country. The same department recorded above-average rainfall in the months of July and August 2010 and monitored the flood wave progression. Discharge levels were comparable to those of the floods of 1988, 1995, and 1997. The monsoon rainfall of 2010 over the whole country was the highest since 1994 and the second highest during last 50 years.
A research by Utah State University analyzed conditional instability, moisture flux, and circulation features and the results support a persistent increase in conditional instability during the July premonsoon phase, accompanied by increased frequency of heavy rainfall events. The increased convective activity during the premonsoon phase agrees with the projected increase in the intensity of heavy rainfall events over northern Pakistan. Large-scale circulation analysis reveals an upper-level cyclonic anomaly over and to the west of Pakistan–a feature empirically associated with weak monsoon. The analysis also suggests that the anomalous circulation in 2010 is not sporadic but rather is part of a long-term trend that defies the typical linkage of strong monsoons with an anomalous anticyclone in the upper troposphere.
An article in the New Scientist attributed the cause of the exceptional rainfall to "freezing" of the jet stream, a phenomenon that reportedly also caused unprecedented heat waves and wildfires in Russia as well as the 2007 United Kingdom floods.
In response to previous Indus River floods in 1973 and 1976, Pakistan created the Federal Flood Commission in 1977. The FFC operates under Pakistan's Ministry of Water and Power. It is charged with executing flood control projects and protecting lives and property of Pakistanis from the impact of floods. Since its inception the FFC has received Rs 87.8 billion. FFC documents show that numerous projects were initiated, funded and completed, but reports indicate that little work has actually been done due to ineffective leadership and corruption.

Flooding and impact

Floods

Monsoon rains were forecast to continue into early August and were described as the worst in this area in the last 80 years. The Pakistan Meteorological Department reported that over of rain fell over a 24-hour period in Khyber Pakhtunkhwa and Punjab. A record-breaking rain fell in Peshawar during 24 hours; the previous record was of rain in April 2009. On 28 July, the same heavy rains contributed to the crash of Airblue Flight 202 in the Margalla Hills. On 30 July 500,000 or more people had been displaced from their homes. On 30 July, Manuel Bessler, head of the UN Office for the Coordination of Humanitarian Affairs, stated that 36 districts were involved, and 950,000 people were affected, although within a day, reports increased that number to as high as a million, and by mid-August they increased the number to nearly 20 million affected.
By mid-August, according to the governmental Federal Flood Commission, the floods had caused the deaths of at least 1,540 people, while 2,088 people had received injuries, 557,226 houses had been destroyed, and over 6 million people had been displaced. One month later, the tally had risen to 1,781 deaths, 2,966 people with injuries, and more than 1.89 million homes destroyed.
The Khyber Pakhtunkhwa provincial minister of information, Mian Iftikhar Hussain, said "the infrastructure of this province was already destroyed by terrorism. Whatever was left was finished off by these floods." He also called the floods "the worst calamity in our history." Four million Pakistanis were left with food shortages.
The Karakoram Highway, which connects Pakistan with China, was closed after a bridge was destroyed. The ongoing devastating floods in Pakistan will have a severe impact on an already vulnerable population, according to the International Committee of the Red Cross. In addition to all the other damage the floods caused, floodwater destroyed much of the health care infrastructure in the worst-affected areas, leaving inhabitants especially vulnerable to water-borne disease. In Sindh, the Indus River burst its banks near Sukkur on 8 August, submerging the village of Mor Khan Jatoi. Law and order disappeared, mainly in Sindh. Looters took advantage of the floods by ransacking abandoned homes using boats.
In early August, the heaviest flooding moved southward along the Indus River from severely affected northern regions toward western Punjab, where at least of cropland were destroyed, and toward the southern province of Sindh. The affected crops included cotton, sugarcane, rice, pulses, tobacco and animal fodder. Floodwaters and rain destroyed of cotton, acres each of rice and cane, 500,000 tonnes of wheat and of animal fodder. According to the Pakistan Cotton Ginners Association, the floods destroyed 2 million bales of cotton, which increased futures prices. 170,000 citizens of the historic Sindh town of Thatta fled advancing flood waters on 27 August.
By mid-September the floods generally had begun to recede, although in some areas, such as Sindh, new floods were reported; the majority of the displaced persons had not been able to return home.

Heavy rainfalls recorded during the wet spell of July 2010

Heavy rainfalls of more than were recorded during the four-day wet spell from 27 to 30 July 2010 in the provinces of Khyber Pakhtunkhwa and Punjab based on data from the Pakistan Meteorological Department.

The power infrastructure of Pakistan also took a severe blow from the floods, which damaged about 10,000 transmission lines and transformers, feeders and power houses in different flood-hit areas. Flood water inundated Jinnah Hydro power. The damage caused a power shortfall of 3.135 gigawatts.
Infectious diseases due to lack of clean drinking water and sanitation pose a serious new risk to flood victims. On 14 August, the first documented case of cholera emerged in the town of Mingora, striking fear into millions of stranded flood victims, who were already suffering from gastroenteritis and diarrhoea. Pakistan also faced a malaria outbreak.
The International Red Cross reported that unexploded ordnance, such as mines and artillery shells, had been flushed downstream by the floods from areas in Kashmir and Waziristan and scattered in low-lying areas, posing a future risk to returning inhabitants.
The United Nations estimated that 800,000 people were cut off by floods in Pakistan and were only reachable by air. It also stated that at least 40 more helicopters are needed to ferry lifesaving aid to increasingly desperate people. Many of those cut off are in the mountainous northwest, where roads and bridges have been swept away.
By order of President Asif Ali Zardari, there were no official celebrations of Pakistan's 63rd Independence Day on 14 August, due to the calamity.
