This special issue of the Water Policy journal looks at the challenges of water management in 12 towns from four corners of the Himalayan region. These include, from west to east, Murree and Havelian in Pakistan; Kathmandu, Bharatpur, Tansen, and Damauli in Nepal; Mussoorie, Devprayag, Singtam, Kalimpong, and Darjeeling in India; and Sylhet in Bangladesh. All these cities face challenges of changing water budgets, increasing demand for water, and water scarcity, which is discussed in the papers. They also map future challenges that these towns will face in a ‘business as usual’ scenario. These cases draw from primary research and fill an important knowledge gap about the status of water resources and water supply in Himalayan towns. Authored by a multi-disciplinary team consisting of physical and social scientists, anthropologists, geographers, and planners, the papers highlight the concerns around unplanned and haphazard development in the region, which is leading to problems of inequity in water supply and unequal developmental outcomes. They also identify areas for future research and action on urban issues in the region.
