Pakistan: Devastating flood, one year later.

Devastating floods, driven by unprecedented monsoon rains, began late in July 2010, leaving one-fifth of Pakistan submerged. The rains in the Khyber Pakhtunkhwa, Sindh, Punjab and Balochistan regions of Pakistan directly affected 20 million people mostly by destruction of property, livelihood and infrastructure. It left 2,000 people dead and 11 million homeless. In this post, we revisit some of those affected as the monsoon season approaches the region again.
