Individuals with diverse abilities have often been marginalized socially, politically, and economically. As a physical manifestation of social inequities, many community systems do not readily engage or accommodate people with disabilities. Community engagement theories prioritize the audiences, or voices, that are often marginalized, so it is critically vital for professionals, scholars, and community leaders to be sensitive to the emotive and cognitive challenges of diverse audiences. Creating ecosystems that are representative and inclusive of many voices can improve the quality of life for marginalized groups. Each community is a unique cultural and natural variety with the potential to engage the skills and experiences of every community member. Engagement is the process by which vested stakeholders, such as residents of a rural village, interact with professionals and other stakeholders to develop a unified voice regarding the short-term problems and long-term goals facing the community. Engaged stakeholders work in cooperation with planners and funders on project design, implementation, and evaluation. The purpose of this chapter is to help its audience understand the why and the how of community engagement and empowerment. Specifically, this chapter will help people understand (1) several different definitions and concepts of community engagement and empowerment and what is at their core; (2) the many tangible benefits of engaging the community, particularly the effect these strategies have on ensuring that everyone benefits from and has a stake in the environmental sector; and (3) a process for the practice of community engagement.
