A systematic and bibliometric review on urban governance and circular economy pathways for municipal solid waste management in South Asia

Municipal solid waste (MSW) management in South Asia represents one of the most pressing urban governance challenges, shaped by rapid urbanization, institutional fragmentation, and weak integration of circular economy principles. This paper undertakes a decade-long systematic and bibliometric review (2015–2025) of 592 peer-reviewed studies retrieved from Scopus applying PRISMA guidelines. The bibliometric analysis demonstrates a steep rise in scholarly output, from fewer than 30 papers in 2015 to over 130 in 2024, with India and Bangladesh accounting for the majority of contributions, while smaller states such as Bhutan, Maldives, and Afghanistan remain underrepresented. Research is concentrated in engineering and environmental sciences, with keyword clusters shifting from traditional waste disposal and landfilling toward circular economy, recycling, and governance integration. Across the systematic evidence base, India, Bangladesh, and Pakistan generate over 80% of South Asia’s MSW yet recycle less than 25%, highlighting systemic deficiencies in policy coherence, financing, and informal sector recognition. This study contributes uniquely by benchmarking governance frameworks across eight South Asian countries, aligning technological and policy innovations with sustainability pathways, and advancing a regional roadmap for inclusive, circular, and resilient MSW governance.
