DELHI

Delhi is the seventh most populous metropolis in the world with a population of 15.3 million (2005 figure). Delhi's metropolitan area, informally known as the National Capital Region (NCR), comprises of the NCT and the neighbouring satellite towns of Faridabad and Gurgaon in Haryana, and Noida and Ghaziabad in Uttar Pradesh making it the sixth most populous agglomeration in the world, with an estimated population of 19.7 million[1].

Delhi has the most vibrant history among prominent cities or towns of India. Delhi was the capital of several empires in ancient India and has over 60,000 recognized monuments[2] built over several millennia. Delhi derives its historic importance from its position in northern India between the Aravalli Hills to the southwest and the Yamuna river on whose western banks it stands. This enabled it to dominate the old trade routes from northwest India to the plains of the Ganges. As a result, it has always been an important cultural and intellectual centre. Due to a high migration rate, Delhi registers as one of the fastest growing cities in Asia. As a consequence, it faces key issues like environmental degradation, air and water pollution, traffic congestion and acute power and water shortages.
