Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 5
Abstract
Urban Greens are technically new term considering the literature related to urban areas. The definitions of urban areas are not uniform all over the world, it varies country to country. In general urban areas are locations characterized by non-agricultural human population density and large human-built features in comparison to the areas surrounding it. Urban greens are related to vegetation greenness of a particular urban area which strikes the micro climate of that area. The purpose of this paper is to make an inventory of the extent and nature of the urban greens in Patna Municipal Corporation. Time series data analysis of Normalized Difference Vegetation Index (NDVI) is widely and commonly used for the study of spatiotemporal analysis of vegetation cover and effective greenness. The present study of the urban greens under Patna Municipal Corporation has also used the NDVI based method for the assessment of its rapid decline in last quarter century (1989 -2014). Six base years (1989, 1993, 1999, 2005, 2009, and 2014) were taken for the assessment and the results show that in last twenty one years the area under urban greens has shrunk to the one third of what it was in 1993, while the Built-up area has more than tripled in the last quarter century.
