Supporting policymaking and evidence-gathering for health impact assessment

Health impact assessment (HIA) is a valuable tool for helping to develop policy and assist decision-makers by drawing on the needs and opinions of all stakeholders connected to a project, policy, or programme.

WHO works with partners and Member States to encourage use of health impact assessment around the world. This emphasis is guided by several strategic directions aimed at addressing the underlying social and economic determinants of health through policies and programmes that enhance health equity and integrate pro-poor, gender-responsive and human rights-based approaches. HIA is also supported with the goal of promoting a healthier environment, intensifying primary prevention and influencing public policies in all sectors to address the root causes of environmental threats to health.

WHO provides guidance on policymaking and evidence-gathering for HIA within the context of sustainable development. The Organization contributes to negotiations on new strategic environmental assessment protocols and collaborates with partners on pilot projects using the HIA approach.  Sharing knowledge, resources and skills, creating networks of colleagues and experiencing new ways of working are among the benefits of such collaborations.
