6. Intersectoral basis of mortality
(WHO 2009)
Sectors assessed for adaptation support
(World Bank 2009)
Agriculture, forest & fisheries
Infrastructure
Water supply
Health
Coastal zones
Extreme weather
Annual deaths linked to selected related risks
(WHO 2008, 2009)
3.5 million undernutrition
2 million indoor air pollution
2 million diarrhoea
900,000 malaria
30, ,000 extreme weather
Somewhat artificial separation as many of the sector impacts are inter related wrt health, but illustrates the current health impacts reported and estimated by WHO. References for all figures given in WHO, Protecting Health From Climate Change: Connecting Science, Policy and People, World Health Organization, Geneva; page ml
WHO estimates that climate change currently causes over 140,000 deaths/year – with highest impacts in Africa 6 6

7. Climate Change Health Impacts
Increased malnutrition & related disorders, including those relating to child growth and development (FOOD)
Diarrheal/water borne/water washed diseases (WATER)
Higher temperatures expand range of vector-borne diseases, such as malaria (OUTBREAKS)
Floods, storms, fires and droughts (DISASTERS)
Multiplier effect on existing health problems, small tipping points adversely affecting large numbers of people at risk (large scale vulnerability), extreme weather events, increased risk of new and unexpected outbreaks. 7

8. Hunger and Food Security
One out of four children in West Africa are underweight ~600,000 children under the age of five in the region die annually from causes related to malnutrition
UNICEF September 2011
Daily calorie intake in almost half of all SADC
countries has declined compared to the early nineties

If SCLP’s contribute, even in a small way to declining food security, the impacts may be large ie small incremental shifts tipping points 8

9. SLCP’s: Adverse Health Impacts
Exposure to IAP from solid biomass fuels associated with COPD (adults) and ALRI’s (children) plus several other adverse health effects
Acute lower respiratory infections (ALRI’s) are the single leading cause of death of children under 5 years old worldwide
Risk factors include nutritional status, crowding
Poverty Hunger Respiratory Disease
Young children especially susceptible to ALRI through IAP for a number of reasons including immaturity of lung linings and immune systems which are not fully developed. Also a gender bias. Also clearly inter related factors of hunger and poverty 9

10. South Africa: SLCP and IAP
Relatively well researched
Post 1994 policies aimed at reducing IAP
Relative risk for childhood mortality due to ALRI is 1.95 in homes burning polluting fuels
Introduction of cleaner energy (electricity) significantly
protective of respiratory health
Barnes, B. Mathee, A. Thomas E. and Bruce, N Household energy, indoor air pollution and child respiratory health in South Africa. Journal of Energy in South Africa. Vol 20 No 1.
Young children especially susceptible to ALRI through IAP for a number of reasons including immaturity of lung linings and immune systems which are not fully developed. Also a gender bias. Also clearly inter related factors of hunger and poverty 10

11. Key Gaps Few recognized studies and little regional research
International literature-extrapolated/derivative data
Health sector–more immediate priorities
Inadequate disease surveillance and poor public health data
SLCP’s –direct health benefits through IAP/outdoor air pollution particularly through improved cookstove tech positive impact incl gender and child health but also improved food security. Complex interrelated-but intuitively it is clear that even small improvements have potential to dramatically increase resilience and adaptive capacity.

12. Leadership commitments
‘2nd Interministerial Conference on Health and Environment in Africa
‘Joint Statement on Climate Change and Health’
Angola 2010
Resolution (AFR-RC61-10)
‘Framework for Public Health Adaptation to Climate Change in the African Region’
September 2011
Second Interministerial Conference on Health and Environment in Africa that took place in Angola in 2010, African ministers of health and of environment committed to adopt the Joint Statement of on Climate Change and Health in Africa

13. Responses
‘ ..while there is uncertainty  regarding the exact impact of climate change on health,  fortunately, there is much less uncertainty around the best responses. These include, .. greater and more resilient coverage of water and sanitation resources. They also include improvements to protect health both from extreme weather events, and any long-term degradation in the environmental determinants of health, such as air quality, the availability of fresh water, and food security. All of these interventions would both save lives now, and increase resilience to gradual climate change.’ 
Campbell-Lendrum D et al: Bulletin of the World Health Organization 2010;88:
In period of uncertainty, need to be careful to advocate actions and responses that will meet current and anticipated future needs. This statement from WHO advocates a pragmatic approach that is valid and responsible. No regret strategiesThey also include improvements in climate-risk management, to protect health both from extreme weather events, and any long-term degradation in the environmental determinants of health, such as air quality, the availability of fresh water, and food security. All of these interventions would both save lives now, and increase resilience to gradual climate change.
