Health Impact Assessment (HIA)

Human health and dams

Resource/Evaluation type


Subject area




The intended development objectives of dams, including poverty reduction, are invariably accompanied by a range of unintended impacts on the natural environment and on human communities. These communities may be affected in quite different ways and, as well as beneficiaries, there are potential losers. It is this observation of health benefit inequity that forms a central theme in the present submission. Informed action can protect vulnerable groups against increased health risks and ensure a more equitable distribution of benefits, including health benefits.
