An HIA is a combination of procedures, methods, and tools to assess the potential health impacts of a project on nearby populations, and to recommend mitigation measures. HIA addresses both negative and positive aspects of health. HIA will also try to identify benefits to health that may be enhanced. It may be necessary to include assessment of health impacts in the environmental and social assessment process, depending on their potential significance. HIA is applicable across industrial sectors (such as agribusiness, infrastructure, extractive industries) and project settings (such as urban, rural, greenfield, brownfield).
