The health effects of climate change
Climate change
produce local health impacts
and increase inequalities
Climate change begins with…
the most vulnerable groups:
Children under 5;
Pregnant women;
Elderly people;
Marginalized rural, urban
and indigenous populations;
Displazed persons
The most vulnerable to environmental changes are
the least responsible for their cause
Climate change: children are the worst affected
88% of the burden of disease attributable to
climate change affects children under 5
climate change begins with…
the most vulnerable regions:
With high transmission of climate
sensitive diseases;
Low food production;
Water scarcity;
Island and coastal cities
Mountain communities
Climate change begins with…
the most important
public health problems:
Communicable diseases;
Food security;
Disaster risks
Water quality and access
Disease vectors
Many of the major killers are climate sensitive
- Each year:
- Undernutrition kills 3.5 million
- Diarrhoea kills 2.2 million
- Malaria kills over 900 thousand
Each of these is highly sensitive to temperature
and precipitation
Basic concepts
The Climate Change challenge
An agenda for action
Global Workplan for addressing the implications of climate change for health
and health systems
Workplan Aims:
• Support health systems in all countries, in order to enhance capacity for assessing
and monitoring health vulnerability, risks and impacts due to climate change;
• Identify strategies and actions to protect human health, particularly of the most
vulnerable groups; and
• Share knowledge and good practices.

Addressing the
implications of

for health Partnerships
Raising
awareness
Workplan Objectives:
1. Raising awareness of the effects of climate change on health, in order to prompt
action for public health measures.
2. Engage in partnerships with other United Nations organizations and sectors other
than the health sector at national, regional and international levels, in order to ensure
that health protection and health promotion are central to climate change adaptation
and mitigation policies
3. Promote and support the generation of scientific evidence
4. Strengthen health systems to cope with the health threats posed by climate
change, including emergencies related to extreme weather events and sea-level rise
Actions from the local to the global setting
