Archipelago (17,500 islands, land area 38% or 2 km2,
sea area 62% or 3.1 km2)
Coastal line 81,000 km
Sixty five percent of the population living in coastal area

VULNERABILITY
• Located in the ring of fire
• Large forest area threatened by deforestation and forest
fire
• Extreme weather
– drought and flood
– cyclone


• Sea level rise

– coral bleaching
– sinking islands

• Fragile ecosystem
– land slide
– peat (gambut)
– biodiversity

LOSS OF BIODIVERSITY

BIODIVERSITY HOT SPOT
Climate change has already
affected biodiversity, and is most
likely to continue to affect
biodiversity on a greater scale.

There is a danger that certain
measures to mitigate climate
change such as increasing forest
plantations and biofuel production
may contribute to more
biodiversity degradation

Pathways from Driving Forces to
Potential Health Impacts


Corvalan et al., 2003

Direct Effects of Climate Change
on Vector-borne Disease
• Climate change has the potential to

– Increase range or abundance of animal
reservoirs and/or arthropod vectors
• (e.g., Malaria, Schistosomiasis, Lyme)

– Enhance transmission

• (e.g., West Nile virus and other arboviruses)

– Increase importation of vectors or pathogens
• (e.g., Dengue, Chikungunya, West Nile virus)

– Increase animal disease risk and potential
human risk
• (e.g., Trypanosomiasis)


Greer et al., 2008

Vector Survival
• Direct effects of temperature on mortality
rates*
• Temperature effects on development: at low
temperatures, lifecycle lengthens and
mortality outstrips fecundity*
* Non-linear

(quadratic)
relationships
with temperature

Summary of Climate Change
Effects

• Climate change has the potential to

– Increase range or abundance of animal reservoirs
and/or arthropod vectors
• Lyme, Malaria, Schistosomiasis

– Prolong transmission cycle

• Malaria, West Nile virus, and other arboviruses

– Increase importation of vectors or animal
reservoirs
• Dengue, Chikungunya, West Nile virus

– Increase animal disease risk and potential human
risk
• African trypanosomiasis

Case Study I: Malaria


Case Study I: Malaria (cont.)
• 40% world population at risk
• 500 million severely ill
• Climate sensitive disease1

Estimated incidence of clinical malaria episodes (WHO)

– No transmission where mosquitoes
cannot survive
– Anopheles: optimal adult
development 28-32ºC
– P falciparum transmission: 16-33ºC

• Highland malaria2
– Areas on the edges of endemic
regions

• Global warming  El Niño3
– Outbreaks
