The DEC itself raised GBP 41million and member agencies raised GBP 30 million, an appeal only surpassed by amounts raised for the 2004 tsunami and 2010 Haiti earthquake.
Monsoon rains that began in late July 2010 were the most severe in Pakistan's history. The flash flooding in the mountains of the north-west eventually spread to the south, through the Indus and other river systems, to engulf an area the size of the UK. Aid provided emergency shelter for 290,000 people, clean water for 510,000, and safe toilets for 160,000.
Figures for the Pakistan appeal were released as the DEC published a report by the ThinkAhead international development consultancy, which assessed the DEC's response to the floods.
The report found that DEC agencies initially struggled to meet the most urgent needs of the worst affected survivors as they began returning in vast numbers from temporary camps to their ruined villages within weeks of being displaced.
"All disasters are a tragedy for those caught up in them, but the Pakistan floods were exceptional because of the vast number of people affected," said the DEC chief executive, Brendan Gormley. "The response to our appeal was extremely generous and the UK public can be proud that the massive aid effort they helped fund has already provided support to 1.8 million people."
The report urged agencies to carefully pick local NGO partners, given the negative image of local NGOs in some areas and to engage with "women more strategically and use them as agents of positive change". One way of doing this, the report said, is to hire more women in aid teams and to set up separate committees for women and girls.
A report in 'The Guardian' said agencies were also urged to assemble and pass on information that would help deal with future emergencies.
The evaluation of the response to last year's floods comes amid a UN warning of people at risk from floods expected in the coming months. The UN said last week that up to 5 million people in Pakistan are at risk, partly due to poor reconstruction and the inadequate rehabilitation of survivors from last year's disaster.
However, as Pakistan braces itself for its annual monsoon season which runs from late June to early September the UN says authorities and aid organisations have learned lessons and are better prepared, even for the worst case scenario.
The UN last year appealed to the world for almost $2bn, the biggest appeal launched by the body for any humanitarian emergency. Yet 30% of the appeal remains unfunded almost one year on.
