The National Capital Territory of Delhi (NCT) is both a city, and a union territory of India. Almost 17 million people live there, and the urban area which extends beyond the NCT is home to over 26 million people. Delhi is home to an estimated 23,000 US$ millionaires, but half of the population live in slum areas with inadequate provision of basic services. Reading that reminds me of the challenges facing Cape Town. I love the idea of 'sister cities'. At city level - politics becomes less abstract given the obvious contrasts, and real world implementation challenges. Delhi is sister city to New York, London, Moscow, Ulaanbataar, Chicago, Kuala Lumpur, Tokyo, Seoul and Fukuoka. The bigger things get, the more abstract they get. When it comes down to conversation, and listening, we can start to taste the common ingredients.
