Abstract
The change of land use plays a major role in the developmental activity of a developing country. Due to rapid growth of urbanisation and dramatic increasing population, the fertile agricultural land has been converted to built-up area with respect to the demand for housing requirement and to the need for basic infrastructure facilities. The quantum of open space and surface water bodies has also been encroached. There has been a rapid growth of population in Puducherry city from 3.48 million in 1991 to 5.44 million in 2011. Hence the conservation of natural resources becomes one of the major challenges especially in small and medium town. This study was conducted to assess the effect of change on land use in urban agglomeration area of Puducherry city for the duration period from 1997 to 2017. There has been an increase in population in Puducherry city mainly attributed to higher scale of migration from adjoining rural areas and medium town for better education, job opportunities and quality life. Hence, it has been strongly recommended for stringent Development Control Regulations to quantify the urban sprawl and manage the impact of urbanisation of land use/land cover in Puducherry city.
Highlights
Land use is derived from the human utility of land and can mainly be classified into residential, agricultural, commercial use, industrial, etc
Satellite data, topography sheets of the study area obtained from Survey of India (SOI), Revenue Village map, Comprehensive Development Plan report for Puducherry city and Indian Remote Sensing (IRS) LISS-III images will be utilised to understand the dynamic phenomenon such as urban sprawl/growth and for land use change detection/analysis
The urban sprawl has been replacing a large area of highly precious agricultural land and as a result the changing land use of Puducherry city as been shown in Figure 3 & Figure 4
Summary
Land use is derived from the human utility of land and can mainly be classified into residential, agricultural, commercial use, industrial, etc. Urban area covers a very small portion of the world land surface Their delineation has significantly changed the natural landscape, created enormous environmental and social impact at local, regional and global scale [2]. Due to cost effectiveness and temporal frequency, remote sensing is mostly employed for changes of land use detection analysis [14]. It has great potential for the acquisition of detailed and accurate surface information for managing and planning urban reforms [15]. Arc GIS is one of the best software tools to analyze the spatial data which can show attribute data with respect to land use analysis for rapid growth of cities
