Because of concerns about the environmental impact of the cyclones and associated floods, the Joint UNEP-OCHA Environment Unit, in close collaboration with OCHA’s Field Coordination Support Section (FCSS), provided an environmental expert as an associate member to the UNDAC team. This expert, from the United Nations Environment Programme (UNEP), was tasked to undertake a Rapid Environmental Assessment (REA) to identify any urgent and life threatening secondary environmental impacts and risks.
