Knowledge, data and interests: Challenges in participation of diverse stakeholders in HIA

Stakeholder participation is considered an integral part of HIA. However, the challenges that participation implies in a multi-disciplinary and multi-ethnic society are less studied. This paper presents the manifestations of the multiplicity of sectors and population groups in HIA and discusses the challenges that such diversity imposes. Specifically, there is no common ground between participants, as their positions entail contradictory knowledge regarding the current situation, reliance on distinct data and conflicting interests. This entails usage of multiple professional and ethnic languages, disagreements regarding the definition of health and prioritizing health issues in HIA, and divergent perceptions of risk. These differences between participants are embedded culturally, socially, individually and, maybe most importantly, professionally. This complex picture of diverse stakeholder attributes is grounded in a case study of stakeholder participation in HIA, regarding zoning of a hazardous industry site in Israel. The implication is that participatory HIAs should address the multiplicity of stakeholders and types of knowledge, data and interests in a more comprehensive way. ► This paper analyses challenges in participation of diverse stakeholders in HIA. ► The multiplicity of disciplines and population groups raises fundamental challenges. ► Stakeholders possess distinct and often contradictory knowledge, data and interests. ► They speak different languages, and differ on approaches to health and risk perceptions. ► Substantial amendments to diverse participation are needed, in HIA and generally.
