Professor Shukra Raj Paudel's research lab focuses on sustainable water resource management, with a strong emphasis on wastewater treatment, reuse, and the environmental impacts of aquaculture and urbanization in South Asia. The lab investigates innovative solutions such as biogas recovery from wastewater through anaerobic digestion and the reduction of greenhouse gas emissions, particularly nitrous oxide, from aquaculture systems. It also explores institutional and infrastructural challenges in achieving sustainable sanitation and hygiene (WASH) services, especially in rapidly urbanizing regions like Nepal’s Kathmandu Valley. The lab’s work bridges environmental engineering, climate resilience, and policy development to support the achievement of Sustainable Development Goals (SDGs).

Access to water, sanitation, and hygiene (WASH) has been a challenge to south Asia’s rapidly growing and climate change-sensitive region. Nepal, a water-abundant country, faces obstacles to fulfilling the highly prioritized WASH Sustainable Development Goal 6 (SDG 6). This review offers details about Nepal’s WASH status from 2000 to 2020 with regard to the challenges Nepal had in delivering reliable WASH services to the people, as well as opportunities for a sustainable way forward, and provides
ABSTRACT Rapid urbanization has caused a worldwide increase in the discharge of wastewater effluent. Although Nepal has a noteworthy history of wastewater management, progress in this field has been hindered by persistent issues. These problems encompass insufficient sewer coverage, deficient treatment and sludge disposal facilities, inadequate treatment infrastructure, lack of coherent institutional frameworks, and a lack of comprehensive planning. This review provides a glimpse into Nepal's cu
Despite having densely populated and highly water-stressed regions, wastewater treatment is limited in South Asia and its reuse for agriculture is mostly restricted to untreated or partially treated wastewater. Adequately treated wastewater or reclaimed water (RW) reuse for irrigation is mostly absent. Thus, this review examines the current status and challenges hampering RW reuse for irrigation in South Asia. In accordance with currently published literature, only India reuses RW for irrigation
