The ongoing urbanization and population increase in Agra have exacerbated the expansion of slum areas, resulting in considerable difficulties in garbage management. The deficient waste disposal systems in these regions result in various environmental dangers, endangering human health. This study examines waste management practices in the slum regions of Agra, emphasizing their effects on health and the environment. The research identifies significant difficulties, including inadequate infrastructure, insufficient public knowledge, and incorrect garbage disposal, through field surveys, interviews with local residents, and trash disposal analysis. The resultant effects, encompassing water contamination, air pollution, and disease proliferation, are examined in detail. A parallel to the Mahakumbh celebration in Prayagraj—where millions gather—underscores the necessity of extensive waste management systems in densely populated regions. During the Mahakumbh, significant efforts are undertaken to manage waste efficiently and reduce its environmental impact, serving as an example for cities such as Agra. This report advocates for enhanced policy and infrastructure development to mitigate environmental and health concerns in Agra's slum regions by prioritizing community engagement, improved waste segregation practices, and sustainable waste management solutions. The waste management practices of the Mahakumbh provide significant insights into how collaborative initiatives at both community and policy levels might alleviate comparable issues in urban slums.
