The significant technique used extensively for determining whether plans, strategies and proposals are likely to have a good or negative effect on health and health equity is the health impact assessment (HIA). It facilitates cooperation with individuals or organizations that guarantee ownership of the action and contribute perspectives. In reality, though, HIA is frequently conducted after decisions have already been made, and many of its predicted effects are only marginally resolved. Effective community participation can enhance health outcomes and have good implications on other community objectives including education, housing, and employment. HIA uses knowledge and the following five steps of screening, scoping, evaluation, suggestions and reporting, review, and reflection to identify potential impacts, their sort and scale, and the populations that could potentially be impacted. This chapter focuses on to facilitate cooperation with interested parties who guarantee ownership of the action and offer insights.
