[Health Impact Assessment: opportunity for participative decision-making or persuasive tool for decisions already...

The Health Impact Assessment (HIA) has already been tested in dozens of nations, including Italy, and the reflection is now mature enough to allow a first evaluation of its effective capacity to offer an inclusive tool for prevention. The analysis focuses in particular on the HIA ability to address, through a participatory approach, one of its founding values: the democratic nature of decisions with an impact on public health. In most cases, the experiments carried out so far seem to be disappointing: the participation is often absent or performed in a rhetorical form. Sometimes the HIA has even been used in an instrumental way to justify decisions already taken, with the only result to further erode the credibility of experts and institutions. In this work, however, the author will try to show how, on the contrary, a greater involvement in the evaluation and decision-making processes could improve the effectiveness of HIA in terms of prevention, while at the same time promoting a relationship of trust between experts, institutions, and citizens on which to establish an ecologically and socially sustainable development.
