"More than 20 million people in Pakistan were affected by the worst floods in the country’s history in late July 2010 [...] The humanitarian response included efforts to inform people about the services available, and communicate with them about accessing these services. It also included efforts to provide platforms by which people could tell the aid workers about particular help they needed or register complaints about services. However, during the flood response, there was no consistent, broad research that could indicate which communication efforts were most effective. This study is an attempt to start providing this data, and thereby directly support the communication plans and efforts of humanitarian organizations. It assesses the impact of humanitarian information provided to flood-affected populations in Sindh and Punjab three months after the flood, and examines to what degree people received information about help available and how well that information enabled people to get that help and to help themselves."
