<P> Disaster risk reduction (DRR) is a systematic approach to identifying, assessing and reducing the risks of disaster . It aims to reduce socio - economic vulnerabilities to disaster as well as dealing with the environmental and other hazards that trigger them . Here it has been strongly influenced by the mass of research on vulnerability that has appeared in print since the mid-1970s . It is the responsibility of development and relief agencies alike . It should be an integral part of the way such organizations do their work, not an add - on or one - off action . DRR is very wide - ranging: Its scope is much broader and deeper than conventional emergency management . There is potential for DRR initiatives in just about every sector of development and humanitarian work . </P> <P> The most commonly cited definition of DRR is one used by UN agencies such as UNISDR, also known as the UN Office for Disaster Risk Reduction, and UNDP: "The conceptual framework of elements considered with the possibilities to minimize vulnerabilities and disaster risks throughout a society, to avoid (prevention) or to limit (mitigation and preparedness) the adverse impacts of hazards, within the broad context of sustainable development ." </P>
