1. RESPONSIBILITY OF PUBLIC HEALTH SECTOR ON RISK ASSESSMENT OF CLIMATE CHANGE
Prof. Tord Kjellstrom

This presentation is in the morning of the last day (Friday) of the ICOH conference and 45 minutes has been assigned and it is the last keynote address followed by sub-plenaries and the closing ceremony.
Before that, on the first day (Monday) of the conference the sub-committee on Thermal Hazards have a symposium on heat, work and health where I will present a paper on “Comparing different indexes to quantify occupational heat exposure”. The Thermal Hazards sub-committee has its business meeting in the evening of the first conference day.
Dr Zayed from Canada has a symposium on Tuesday titled “Impact of climate change on occupational health and safety” (I don’t know the time yet) with a paper by Kjellstrom on “The ‘Hothaps’ program for climate change impact assessment and prevention”.
I also have a poster accepted on “Occupational health and productivity loss due to climate change”. Poster session on Thursday.
Hopefully this contributions will create justified interest in this part of climate change and health analysis.

2. The climate change and health panorama
Climate change has created new interest in climate conditions and health --- not just change is important, but the current conditions
Mitigation reduces extent of ongoing climate change
Adaptation reduces impacts on human society and health from climate change we can’t avoid
Elderly and children are usually listed as vulnerable groups for climate change, but working age people are also vulnerable, and their health and well-being affects family health and community health ….. the links are important
Health Impact and Risk Assessments are an essential component of effective prevention

13. Other examples related to environmental change and social issues, including mental stress
1. Increased suicides among farmers due to drought and agricultural production failures
2. Reduced ice coverage in Arctic areas affecting traditional working life (fishing, hunting) and creating injury and mental health risks
3. Lack of work, loss of income, in forestry when ground is too soft (not ice hard) for machinery use
4. Longer distances to walk and other difficulties in daily household tasks, because climate change has reduced accessibility of certain basic needs
5. Impact of heat on pregnant women and newborn children
6. Increasing heat reducing childrens’ interest in play and physical activities outdoors ….. potentially increasing obesity risks

14. Public Health Sector focus
Health Services (“sick services”)
Preventive health programs – needs other sectors
Disease and Injury focus (ICD codes):
Early childhood diseases, maternity issues, infectious diseases, vector-borne diseases, injuries, respiratory – heart – kidney etc diseases, cancer, special occupational diseases, other …..
Environmental factors:
Risk Assessment and Environmental Health Impact Assessment

15. Climate change and health in DPSEEA framework

16. Role of Risk Assessment in Prevention
Identify climate factors that can affect health
Current climate situation; Urban Heat Island; analysis linked to cause effect pathways and timing
Potential future climate situation
Population size and change in the future
Population activities change in the future (e.g. work, active transport, play)
Calculate likely impacts for different groups – health equity, environmental justice
Identify short-term and long-term prevention approaches and promote the best ones
Cooperate with technical expertise to find environmentally friendly cooling and protection systems

17. Moving forward in Thailand ……..
Create links between different sectors: raising awareness
Focus on different age groups and consider indirect effects on health and well-being for the family and community: broad Health Impact and Risk Assessment
Establish policies and actions for future homes and workplaces …. building design to reduce air conditioning need, urban design (trees for shading, water feature for cooling, etc)
Test different approaches in the Thailand context and make epidemiological assessments of prevention and adaptation methods
Role of health sector: ….. To discuss …..

18. Discussion points: Role of health sector: ???
HAZARDS OF CONCERN: make list for different parts of Thailand
Risk Assessment; cooperate with other sectors
warning systems,
emergency preparedness,
Specific technical cooling/protection systems
health service rapid response teams,
expertise and advocacy for future development plans,
links to other public health issues (such as obesity prevention)
