Dozens of countries and international institutions on Monday pledged more than $9 billion to help Pakistan recover and rebuild from devastating summer floods that the United Nations chief called “a climate disaster of monumental scale.”

The flooding killed more than 1,700 people, destroyed more than 2 million homes, and covered as much as one-third of the country at one point, causing damage totaling more than $30 billion, U.N. and Pakistani officials say. Large swaths of the country remain underwater, with millions living near contaminated or stagnant waters, the U.N. says.

Wrapping up a day-long conference at the U.N. offices in Geneva, Pakistani Deputy Foreign Minister Hina Rabbani Khar said the final tally came in above a target for the international community to meet half of the estimated $16.3 billion needed to respond to the flooding. The rest is expected to come from the Pakistani government itself.

U.N. pledging conferences often draw promises of big sums from governments, international organizations and other donors, but those don’t always get fulfilled entirely. The Pakistani government has announced plans for independent, outside monitors to make sure that the funds go where they are needed.

The conference shaped up as a test case of how much wealthy nations would pitch in to help developing-world countries like Pakistan manage the impact of climatic swoons, and brace for other disasters.

Achim Steiner, the head of the U.N. Development Program, which helped organize the conference, said Pakistan’s government knows contributors will be looking for outcomes such as in the accountability, clarity, efficiency, transparency and effectiveness of the programs that will be funded.
