Environmental and community health examines how our physical, built, and social surroundings shape population well-being and disease patterns. This text connects exposure science with community-level interventions to reduce risks and promote resilience. It covers air and soil quality, housing, occupational hazards, and the social determinants that mediate exposure effects. Community engagement, participatory assessment methods, and policy levers are presented as tools for sustainable change. Chapters include practical frameworks for needs assessment, risk communication, and program evaluation. Useful for public-health students, municipal planners, and community practitioners focused on upstream prevention.
