The rapid growth of urban area and extraordinary population growth are the most dramatic phenomenon associated with urbanization. This rapid and haphazard growth of urban sprawl and increasing population pressure results in the various adverse effects on urban environment. In India major metropolitan cities are already saturated due to large scale immigration of population. Urban centres and Metropolitan cities are growing haphazardly in all directions without proper planning. Pune is the eighth largest city in India in terms of both population and GDP driven by rapid urbanization. Pune's population will grow up from 5.5 million to 7.7 million by 2030 and it will create severe strain on core urban infrastructure. Pune city lies between 18° 25′ to 18° 37′ North latitude and 73° 44′ to 73° 57′ East longitude. The study area covers 243.84 km 2 composed of 144 general electoral wards. According to 2011 which comes under 14 administrative wards of Pune Municipal Corporation with population with 3.12 million Pune city in India is growing at a very fast rate. In the present study population changes with utility services are considered for sustainable urban environment. In Pune Municipal Corporation each ward's population it is found that uneven distribution of various utility services which leads various problems in management and planning of Pune Municipal Corporation. For present study e-Suvidha centres and 24 hours open medical stores are considered. In PMC 88 e-Suvidha centres and 124 medical stores which are day and night are available.

The Air Quality Index (AQI) is a significant tool of risk communication and reporting system. The main aim of the paper is to comparatively analysis the air quality index of both the Delhi and Chennai. The objective of the study is to compute the AQI of both the cities and to compare it. For both the cities data for the computation of the AQI are taken from the secondary source from Central Pollution Control Board (CPCB) and Tamil Nadu Control Pollution Board (TNP). It is found that in both the city main source of pollution are from both anthropogenic and natural genesis. The pollutants which make the reading of AQI severe is emitted from the transportation sector such as emission from the vehicles, road side dust particles followed by the pollutants from the industries and construction site. In Delhi sandstorms from the desert regions during the summer season and bursting of firecrackers in diwali are responsible for shooting the AQI during March and November month respectively. During monsoon season the AQI value become less in Delhi. In Chennai the AQI value does not very much, throughout the year it remains constant with slight degradation during Diwali and Pongal celebration.
