Delhi

Delhi, a metropolitan region in northern India with about 46 million residents, is grappling with significant public health and environmental concerns. Currently, the city is experiencing a rapid spread of H3N2 influenza, affecting millions. Additionally, post-monsoon pollution levels have surged in the Yamuna River, marked by increased faecal coliform and BOD metrics, despite efforts to beautify ghats for Chhath festivities. To combat severe air pollution, Delhi's government is trialing cloud seeding to induce artificial rain, a strategy proposed since their election this year. The city also faces an annual spike in pollution following Diwali celebrations, with the air quality falling into the 'severe' category post-festival. These issues highlight ongoing challenges in managing health and environmental sustainability in one of the world's most populous metropolitan areas.
