Explanation #
Health Impact Assessment is a systematic process that aims to identify, predict,… #
It considers a wide range of factors, including physical, mental, and social well-being, and seeks to promote health equity and social justice.

The process typically involves several key steps, including:
1. Scoping #
Defining the boundaries of the assessment and identifying the key health issues to be considered.
2. Screening #
Identifying potential health impacts and determining which ones are most significant.
3. Assessment #
Evaluating the magnitude, distribution, and significance of the identified health impacts.
4. Recommendations #
Developing recommendations to mitigate negative health effects and enhance positive ones.
5. Reporting #
Documenting the findings and recommendations in a clear and accessible format for decision-makers and stakeholders.
Example #
An urban development project is proposed in a low #
income neighborhood. A Health Impact Assessment is conducted to assess the potential health effects of the project on the residents. The assessment identifies increased air pollution, decreased access to green spaces, and higher levels of noise as potential health risks. Based on these findings, the assessment recommends measures such as increased green spaces, improved public transportation, and noise reduction strategies to mitigate negative health impacts and promote community well-being.
