Abstract  The Yamuna River, spanning 1,376 kilometres from its source at Yamunotri to its confluence with the Ganga, faces a severe pollution crisis, particularly in its 22-kilometre Delhi stretch, which accounts for 79% of the river’s total pollution despite representing only 2% of its catchment area. Despite substantial budgetary allocations totalling ₹9,178 crores under the […]

Introduction The Yamuna’s pollution is largely contributed to by untreated sewage. It has been largely reported that the Najafgarh and the Shahdara drain contribute significantly to the pollution of the river along its Delhi stretch. The Najafgarh drain, which runs across the southwest part of the city, ultimately meets the river at Wazirabad. The Najafgarh […]

According to a recent life‑cycle assessment of Delhi’s solid waste management system, the city collects around 11,352 tonnes per day of domestic and commercial garbage, which in the absence of adequate segregation and […]

Abstract Over the past decade, efforts to rejuvenate the Yamuna river have been marked by ambitious plans, significant public expenditure, and highly visible interventions along the floodplains. This paper argues that the persistent gaps in the efforts stem from a fragmented and largely cosmetic approach. Drawing on the data from the forestry interventions and the […]

Introduction The history of artificial intelligence is longer than the history of most modern democracies. Yet it was introduced to the public much later in the twentieth century. In 1950, the term Artificial Intelligence (AI) was discussed by an English mathematician and computer science pioneer, Alan Turing, in his paper on computer machinery and intelligence […]

Abstract  India’s rapid renewable energy (RE) transition, including the focus on solar and wind energy, is widely celebrated as a pathway toward low-carbon growth and energy security. The wind sector in India holds enormous untapped potential for energy transition. As government policies now focus on this growth potential, some challenges and constraints need to be […]

Background  The Yamuna River is deeply entrenched in historical & cultural significance but yet it stands as a stark contrast to its once life-giving form. Flowing through the heart of Delhi, the river has been overwhelmed by decades of unchecked urbanisation, untreated sewage, and now stands as a reminder of the ecological consequences of urbanization […]
