2. History
• The evolution of HIA can be viewed as a little different from EIA
• EIA has been strongly focused on major project assessment
in many jurisdictions
• In recent decades it has expanded to encompass other
strategic assessment processes such as strategic
environmental assessment (SEA)

3. History
• HIA can be seen as originating from three separate areas of
activity
• Environmental health
• Social view of health
• Health equity
• Each bring with them their own disciplinary beliefs, values,
support base and baggage
• The role of health risk assessment

Consensus Paper
on HIA
5. International Perspectives
• There are currently several approaches to legislating and
institutionalising HIA’s use:
• Requiring health be considered as party of EIAs or broader
impact assessment (many countries’ EIA legislation; IFC Performance Standards; Equator
Principles; EIA legislation in other regions)
• Requiring stand-alone HIAs on a type/category of proposals
(Thai National Health Act; Lao PDR; Tasmania, Australia)
• Giving health authorities the right to conduct HIAs where
they deem it necessary or appropriate (Victoria, Australia)
• Legislating the right for communities to request HIAs be
conducted or to be involved in them (Thai Constitution)
• Regulations or policies that support HIA’s use but do not
require it (many local governments and authorities in Europe; New South Wales, Australia; New
Zealand)
6. International Perspectives
• Capacity has been a critical factor in determining the extent to
which these legislative mechanisms have been actually
implemented
• The broader Health in All Policies agenda has helped to promote
HIA’s use
7. Opportunities and Threats
• The opportunities and threats to HIA and its use are often the
same
• Better integration of health and HIA into other assessment
processes
• At the moment health is often limited to health risk
assessment that are conducted as stand-alone assessments
within larger assessment processes
• There’s scope for better integrated assessment of health
benefits
8. Where to next?
• We’ve actually come a long way as a field in relatively short time
• In 1995 Birley and Peralta wrote that:
“At present HIA is a blunt tool with the rudiments of an accepted
methodology”
• This is no longer the case. There is greater consensus about the
procedural elements of HIA (e.g. screening, scoping, etc) and
when it is most useful. There is also better evidence about its
effectiveness.
Briley M, Peralta G (1995) Health Impact Assessment of Development Projects in
Environmental and Social Impact Assessment (Eds Vanclay F and Bronstein D), Wiley:
Chichester, p 153-170.
9. Where to next?
• Potential activity:
• Industry-specific HIA guidance, eg mining, wind power, etc
(some already exists)
• Better professional development for advanced practice
• Improved methods for economic appraisal of health impacts
