A risk analysis which includes the affected people in defining problems and needs, deciding solutions to them, implementing agreed activities to achieve those solutions and/or evaluating the results. The benefits of the technique are the growth of capacity, the creation of disaster risk management attitudes and behavior, and a greater insight into the communities enabling better results. In addition participatory analysis may be more cost effective in the long term, than externally-driven initiatives, partly because they are more likely to be sustainable and because the process allows ideas to be tested and refined before adoption. The limitations of the technique are a poor fit within rigid timetables; impact will be limited at best if only some parts of the community are involved and where participation involves real social change it leads to the possibility of confrontation and conflict with those who traditionally hold power and influence.
