What can you tell me about Chennai?
Hello! Chennai is formerly known as Madras and is the capital city of the Indian state of Tamil Nadu. Would you like to know about Chennai's Administration?
Ok, let's hear about that first.
Sure! Chennai is governed by the Greater Corporation which was established in 1688. As the capital of Tamil Nadu, Chennai houses both the state's executive and legislative headquarters in the Secretariat Buildings in the Fort St George campus.
That is pretty interesting, Can you elaborate on the Etymology?
Of course! You know, according to a few different sources, Madras was first derived from Madraspattinam- a fishing village north of Fort St George. It wasn't until 1996 that the government of Tamil Nadu officially changed the name from Madras to Chennai.
Oh wow, That is a big difference. Anything more?
Actually, yes! Even though there has been an official name change, the name Madras continues to occasionally be used for the city. In fact, universities still use old name in their own university titles such as the University of Madras, IIT Madras, and Madras Institute of Technology.
Pretty cool, moving on to the Environment. What can you tell me about it?
I can tell you that against the World Health Organization recommendations of 9 square meters of green coverage per capita in cities, Chennai actually has a percentage of 14.9 as of 2018!
Lucky Country! Anything more on that today?
I'm not so sure about what the percentage would be for 2019, but I can tell you that 65% of the rains received in Chennai are in the monsoon season. This means that Chennai is highly dependent on this season for their rain.
You have been a great book of knowledge today. Thanks!
You are very welcome!
