INDIRECT SPECIFIC - The document does not mention environmental drivers of displacement, but can be applied to all displaced and returned persons. The strategy aims to collect data on the risks and vulnerabilities of populations by assessing needs, analysing them and integrating the results into humanitarian and development programming; provide people in emergency situations with the coordinated and integrated assistance they need to survive; ensure the socio-economic reintegration of IDPs and returnees; strengthen the resilience of vulnerable populations to cope with shocks by responding to early warning signals; and reduce the duration of post-crisis recovery.
