Health Impact Assessment (HIA) has been defined as: "A combination of procedures, methods and tools by which a policy, programme or project may be judged as to its potential effects on the health of a population, and the distribution of those effects within the population" (IMPACT, 2004a). HIA aims to influence public policy in such a way that would enhance the identified positive health impacts and also to mitigate negative impacts. Although community participation has become widely incorporated into the HIA process, there is paucity of research and information regarding the actual value of engaging with local community members in terms of their contributions to the evidence base of HIA (Parry and Wright, 2003). Therefore, in order to evaluate the utility of local knowledge as a source of evidence in HIA, several methods were employed in this study, namely Structured Literature Review (SLR) of twenty completed HIA reports and the completion of questionnaires by 52 HIA practitioners. Other facets of the methodology were semi-structured interview with 11 HIA practitioners, and a fieldwork that entailed the conduct of two health impact assessments. The major findings from this research indicate that 69.2% of the questionnaire respondents had engaged with local residents as part of their evidence base for HIA predictions. 98.4% of these respondents rated their perceived usefulness of local knowledge to be either useful or very useful. Additionally 61.9% of those who had engaged with local residents encountered some differences between local knowledge and expert opinion. All of these put local knowledge in the position of the second most widely used out of 10 different sources of evidence investigated through this study. The implications of these and several other discoveries are examined in various sections of this thesis
