Type: Thesis


Vijayawada is a very fast developing city afterthe declaration as capital. The city grown is in high rate such that at presentit’s lacking green spaces, and rapid growth in urbanization is making city vulnerable in context of occupying natural environment. In this scenario theratio of growth between build up and greenery is done. This analysis is donefor the year 1994, 2000, 2012, and 2016 for Vijayawada city by using Landsatand Resourcesat data. The gain and loss analysis showed the greenery hasincreased 10% till 2012 and then due to drought it has come down to 13% in2016. The build has a steady growth from the year 1994 to 2016 and hasincreased from 9% to 14%. This analysis shows the greenery is affected due tothe urbanization of the city. The next objective that is performed is predictingthe city for the year 2030 and 2050. For this analysis CA Markov is used withmulti-layer perceptron for the prediction. This model can give the details ofland use land cover change for the predicted years. From the analysis the buildhas increased to 47% which is drastic change from the year 2016 and greeneryhas come down to 19%. And for the year 2050 the build has showed further growthof 2% and greenery has stayed same. Due to the rapid urbanization it isimportant to place the green spaces so suitability analysis is performed. Thetechnique that is used is AHP and the factors used are slope, elevation, anddistance from water bodies, distance from urban and population density. Theweights are given to these factors by the experts from municipality of thecity. After analyzing the AHP and calculating the area using the factors thegreen area in the city has shown up in various classes. The total green area isdivided in to more suitable, moderate suitable, suitable, less suitable and notsuitable areas. 11% of land is more suitable in Vijayawada city as per presentanalysis. Concluding, greenery is very important due to various reasons as itreduces the noise, air pollutions and decreases toxicity in the environment soconverting barren lands to green spaces conservation planning is the keyconcern in the analysis, which can be further analyzed for suitable greenspaces in implementing cities.
