The leading metropolises of our country, one the capital and the other its financial hub, have been ranked among the bottom five in a study conducted by a Dutch company, Arcadis. The Sustainable Cities Index 2015 judged 50 major world cities based on social, economic and environmental factors. While European cities like Frankfurt and London were listed as most sustainable in the report, the congested and polluted Indian cities fared poorly on all fronts. The study considered aspects such as standard of living of citizens, income inequality, education, environmental pollution, energy efficiency, cost of living and ease of doing business in cities.

The low rating doesn’t really come as a surprise. It is a known fact that India’s fast growing urban territories are grappling with serious sustainability issues. According to the World Health Organization (WHO), of the 20 most polluted cities in the world, 13 are in India, and New Delhi is at the top of the list.

The alarming level of pollutants in the air are causing serious health issues in the city. Children, especially, suffer from breathing problems and reduced lung capacity. The number of vehicles in New Delhi has increased by 97 percent over the last decade leading to heavy congestion and increased travel time. But vehicles aren’t the primary cause of air pollution in the smog covered capital. Based on a study by IIT Kanpur, road dust like silt, soil or particles from broken and poorly maintained roads are the biggest contributors followed by industrial emissions.

The city is also struggling with contaminated water supply owing to large-scale pollution of water bodies. The Yamuna river is dying because of the sewage water, garbage and industrial effluents that are released into it on a daily basis.

New Delhi’s population is rising due to increased migration. This is straining its infrastructure and space. Close to 50 percent of the residents live in slums and illegal colonies without proper sanitation, water supply or waste management. The city’s waste is mainly tossed into open dumping grounds where the garbage is (in some places) set on fire. Not only is that harmful to the natural environment, it greatly increases the risk of widespread diseases.
