It is important to state from the outset that the implementation of good practices is going to be very difficult, because of constraints in the operating environment. In this particular emergency, international agencies will know less about what happened and how best to respond. One overriding lesson is that agencies will have to find ways of dealing with this uncertainty and its implications for aid programming, accountability and delivery. They will also have to work to explain these issues and their implications to various stakeholders, including the media and donors. This report benefited greatly from ideas and inputs from members of operational agencies who provided vital inputs. For finding the time to contribute to this learning process in the midst of an incredibly challenging crisis context, thanks are due.
