Greenfield airports play a significant role in accelerating the urbanization of a country, although at the same time the development of greenfield airports has some adverse environmental impacts such as use of agricultural land, deforestation, cutting of hills, diversion of rivers and erosion of the sea shores, etc. All these adverse environmental impact have significant ramifications on the environment.
An increase in air-traffic demand in existing airports, increase in level of urbanization and growth of small towns into bigger cities has led to increased pollution and as a result necessitated the need for the development of greenfield airports. The impact of the greenfield airports and urbanization has significant impact on economic growth. The Government of India has decided that during the next 20 years the number of airports will be increased from existing 133 to 500 airports and among them 367 airports will be greenfield airports. Searching sites for a greenfield airport involve a number of activities, such as the identification of the site, obstruction clearance within 30 nautical miles, etc. High rising building, hills, HT lines, forest, industrial chimneys, railway tracks, roads/highways etc., should not create an obstruction for landing and takeoff. Besides, factors such as the wind rose diagram, rainfall, temperature, wind speed, the elevation above mean sea level of the proposed site are also analyzed. In addition to the above constraints the site should have adequate traffic potential and be economically viable.
