People need information as much as water, food, medicine or shelter. Information can save lives, livelihoods and resources. It may be the only form of disaster preparedness that the most vulnerable can afford. The right kind of information leads to a deeper understanding of needs and ways to respond. The wrong information can lead to inappropriate, even dangerous interventions. Information bestows power. Lack of information can make people victims of disaster. Do aid organizations use information to accumulate power for themselves or to empower others? The report calls on agencies to focus less on gathering information for their own needs and more on exchanging information with the people they seek to support.
