Health impacts due to climate change,

noticeable through:

(3)

Water

Too much

Both extremes can have

health effects

(4)

Flooding

• Diarrhoeal diseases

• Vector-borne diseases

• Rodent borne diseases

(5)

More intense tropical storms:

Injuries and death

(6)

Rain-more frequent and heavy

(7)

Too little water...

Drought

Diarrhoea

Skin - scabies

Eye - trachoma

For dengue -

higher temperature

means:

MORE

rain

Increase breeding sites for

mosquitoes

LESS

Can also increase breeding

sites for dengue mosquitoes

EARLY WARNING EARLY ACTION

For health effects?

EARLY DETECTION EARLY ACTION

• Flooding

• Drought

• Heatwaves

• Air quality

(21)

Baseline resilience also important

Water and sanitation

Access to water, sanitation

Knowledge about hygiene

• Vector borne disease

Vector control

Knowledge, behaviour

(22)

From the how-to guide:

1. Collect background info - in contact with

correct partners. Monitor!

2. Integrate CC into NS - awareness, health or

disaster programmes

Consider priority areas, impacts

(23)

Timeframe

Forecast

Action?

Years

Increased risk of rainfall due

to CC

Months

Forecast of strongly above

average rainfall for coming

season

Weeks

High ground saturation

Forecast of continued rainfall.

High risk of floods

Action?

Years

Increased risk of rainfall

due to CC

Map risk-areas. Planning

Improve watsan coverage

Months

Forecast of strongly above

average rainfall for coming

season

Recruit/train more volunteers

Stockpiling

Weeks

High ground saturation

Forecast of continued

rainfall. High risk of floods

Refresher training for

volunteers. Preposition

Days

High water levels

Summary

• Same problems - changing patterns

• Combine detection, surveillance and baseline

with the use of climate information to enhance early

action
