AbstractVijayawada is a very fast developing city after the declaration as capital. The city grown is in high rate such that at present it’s lacking green spaces, and rapid growth in urbanization is making city vulnerable in context of occupying natural environment. In this scenario the ratio of growth between build up and greenery is done. This analysis is done for the year 1994, 2000, 2012, and 2016 for Vija ya wada city by using Landsat and Resources at data. The gain and loss analysis showed the greenery has increased 10% till 2012 and then due to drought it has come down to 13% in 2016. The build has a steady growth from the year 1994 to 2016 and has increased from 9% to 14%. This analysis shows the greenery is affected due to the urbanization of the city. The next objective that is performed is predicting the city for the year 2030 and 2050. For this analysis CA Markov is used with multi - layer perceptron for the prediction. This model can give the details of land use land cover change for the predicted years. From the analysis the build has increased to 47% which is drastic change from the year 2016 and greenery has come down to 19%. And for the year 2050 the build has showed further growth of 2% and greenery has stayed same. Due to the rapid urbanization it is important to place the green spaces so suitability analysis is performed. The technique that is used is AHP and the factors used are slope, elevation, and distance from water bodies, distance from urban and population density. The weights are given to these factors by the experts from municipality of the city. After analyzing the AHP and calculating the area using the factors the green area in the city has shown up in various classes. T he total green area is divided in to more suitable, moderate suitable, suitable, less suitable and not suitable areas. 11% of land is more suitable in Vijayawada city as per present analysis. Concluding, greenery is very important due to various reasons a s it reduces the noise, air pollutions and decreases toxicity in the environment so converting barren lands to green spaces conservation planning is the key concern in the analysis, which can be further analyzed for suitable green spaces in implementing ci ties.
