Hi Leigh,
WWF and EWB do work in the area, but not in disaster management. It is more of an aspirational statement. The way INGOs, and NGOs work, once a disaster hits, it is all hands on deck and everyone pitches in whatever way they can.
UNICEF, WHO, Save the children, World Vision etc are some of the lead agencies in Cambodia’s Humanitarian Response Forum. If it helps.
Cheers,
Sai
