Environment, Climate Change, One Health and Migration
The Department for Environment, Climate Change, One Health and Migration works to prevent disease and promote health by addressing key areas of environmental health including climate change, clean energy; air quality; water, sanitation and hygiene (WASH); and chemicals and radiation. Health threats are addressed through a One Health approach that crosses the human, animal, and environmental sectors.

Healthy urban environments

Rapid urbanization around the globe has led to an ever more critical role for cities to play in protecting and enhancing their citizens' health. Health is an asset and cornerstone for sustainable urban development. Urban health is influenced by a range of personal, social, economic and environmental determinants including housing, transport, urban planning, lead paint, green spaces, air pollution and climate change.

WHO is responding by building the capacity of the health sector to effectively engage in urban health, working across sectors to support cities to produce contextual, meaningful and actionable information on the health, economic and climate impacts of urban environments. WHO offers tools and resources to enable cities to make the case for investments in interventions which effectively address environmental risks to health. WHO also works to build networks of urban health practitioners to exchange best practices, and advocate for scaling up the implementation of health-enhancing urban policies.

When health is prioritized as a catalyst and goal of development strategies, cities have a unique opportunity to address several determinants of health under one administrative jurisdiction, producing multiple benefits for health, the environment and sustainable economic development.
