Scientific data for 
CS-MAP in Cambodia
Training workshop on mapping climate-risks 
and adaptation plans using CS-MAP approach
Phnom Penh, Cambodia | 19-20 December 2022
Current gaps in risk management
Current gaps (World Bank evaluation, 
2019):
• Cambodia needs better data and 
comprehensive vulnerability maps
• Cambodia lacks sufficient capacity to 
properly prepare at the community level 
• There could be better cooperation among 
government
agencies at all levels and with 
nongovernmental partners 
• Scaling up good practices and making 
them sustainable has been a challenge

Flood risk
Number of communes affected (1996-2022)
River Flood:  water overflows river-bed levels and runs slowly on small 
areas or vast regions over a long period of time
Flash Flood: violent water overflows in a watershed
Data source: Cambodia Disaster Damage & Loss Information System Affected: Under flooded for a period of time but can self-restore 
Damaged: Under flooded for a period of time and have yield loss after 
www.cgiar.org flood.

Drought risk
Number of communes affected (1996-2022)
Drought: without rain or with rain deficit during a long period of time. 
In Cambodia, drought causes damage to paddy fields and farming 
crops, and also deficit water use for humans.
Affected: water shortage for a period of time but crop/fish can self-restore 
Damaged: Under water shortage and cause yield loss after drought.
