Floods and Health
50% of flood victims die within the year after the flood
Flood
Increased
exposure to
pathogens,
reduced
drinking
water quality
Direct casualties
Increase in
mosquito
vectors and
associated
diseases
Increase in
effects of
mold in
housing,
other
secondary
effects

Health inequities
10. Vision: co-manage water and public health
• Engage: learn the same language
• Trade-off investments in water /
health
• Equity of benefits
12. WATER
How are humans exposed?
Swimming
Drinking
Cooking
Defecating
Working
Floods
Washing
Inhaling (vapor)
Eating
Bathing
Industry
Pathogens
Open defecation
Domestic effluent
Water-related disease
Agriculture

Scoping + Pilot
- Knowledge review
- Engage stakeholders / partners
- Outline framework
- What is available?
- Gather existing methods / tools
- Start pilots in impacted areas
Pilot + Building
- Work with stakeholders
- (pilot) projects
- Apply tools, integrate
- Evaluate impact
