• Many more died later due to illnesses and diseases

More than 6,000 died in Typhoon Haiyan in the Philippines in 2013

Linking CCA and DRR

• Government agencies dealing with CCA and DRR are separate

• But they starting to collaborate

• This will have to be speeded up

• Coordination mechanisms are needed between institutions

• Mainstream CCA and DRR in land use planning

• Involve local government units and communities
