Use of High Resolution temporal satellite imageries and Geographical Information System (GIS) provide us present and past status of extensions and Landuse change in oukskirts of urban centres. The present paper is an attempt to analyze the temporal urban growth and landuse change of Aligarh city using Survey of India Topographical Map surveyed in 1971 and IKONOS satellite data of various time periods from 2004, 2009 and 2014. The result shows that in 1971 the urban built-up land of the city based on SOI Topographical Map was 2224.6555 hectare, based on interpretation of IKONOS satellite imagery of 2004, 2009 and 2014 , the urban built-up area of the city is 4724.7614 hectare in 2004, 5872.6774 hectare in 2009 and 7059.8875 hectare in 2014 respectively. This has increased to 2500.1059 hectare in a period of 33 years from 1971 to 2004 and in the period from 2004-2009 and 2009-2014 it has increased by 1148 hectare and 1187.211 hectare respectively. Agricultural land, Orchard/Plantations and water bodies to built-up (urban) has been calculated in GIS and it has been observed that there is a tremendous increase in the built-up urban area. The loss of prime arable land, orchard/plantation and water bodies has been converted in to built-up urban land. The digital database created for urban growth and landuse change of Aligarh city, Uttar Pradesh, India using multi-date data in Arc-GIS software would be very useful for urban development authorities, planners, decision makers for better landuse planning and management for proposed landuse programmes.

During past four decades, in post economic reforms period, Delhi and its surrounding regions has attracted a large number of populations which led to the rapid transformation of its LULC pattern. Therefore, this study is aimed to analyze the LULC changes during 1990-2018 as well as the growth and pattern of built-up surfaces in relation to the population growth and migration in the suburbs of Delhi metropolitan city which is also known as the National Capital Region (NCR). The Landsat 5 (TM) and Landsat 8 (OLI/TIRS) data has been used for the LU/LC classification of Delhi NCR. The K means clustering technique was applied on the Landsat data for the LULC classification and then the change detection technique was used to quantify the LULC change. The result shows that the considerable changes in LULC have occurred with continuous increase in built-up area and open/fallow land and decrease in agriculture land and vegetation over the study time period. Built-up area increased by about 326 percent and open/fallow land by 44 percent while the agricultural land and vegetation cover have decreased by 12 percent and 34 percent of the total area of study respectively during the study period. Built-up area has mostly increased at the expense of agricultural land and vegetation cover while vegetation cover has been transformed into Built-up area, Ridge and Agriculture. The statistical analysis shows that the association between built-up expansion and the population and migrants varies from weak to high but the coefficient of determination was always positive.
Monitoring land use change and its drivers in Delhi, India using multi-temporal satellite data
Modeling Earth Systems and Environment, 2016
Urbanization is the primary driver of Land Use/ Land Cover (LULC) changes throughout the world. It is arguably the most dramatic and prevalent form of irreversible land transformation. In a fast growing city like Delhi, land use changes are tremendous. Therefore, it is imperative to analyze the driving forces of such change. Along with Delhi, the South West District of Delhi has been chosen for a comparative study of LULC change from 1977 to 2014. Landsat and Indian Remote Sensing (IRS) satellite scenes were used to perform both supervised and unsupervised classification and an overall accuracy of over 90 % was achieved for all the years. In Delhi, net percent change from 1977 to 2014 was found to be ?30.61 % for built-up area,-22.75 % for cultivated area,-5.31 % for dense forest,-2.76 % for wasteland and ?2.41 % for road/rail network. No major net percent change was seen in open forest, scrubs/degraded forest, plantations and river/ waterbody. The LULC results provide evidence of relationship between built-up area, agricultural land and wasteland over the past four decades. The effect of economic reforms of 1991 has manifested itself as a change in LULC. Overall it illustrates a characteristic picture of LULC change and its dynamics.
MONITORING URBAN EXPANSION AND LAND USE/LAND COVER CHANGES OF AGARTALA CITY, TRIPURA, INDIA
Indian Journal of Regional Science, 2020
In developing countries like India the growth of urban area generally depends on the importance of the economic, administrative and the institutional functions of the area. With the increase of small and medium or big industries in and around the area, market places, business centres, establishment of different offices, institutions, the importance of the area grows fast and primarily to avail the opportunity of various income generation avenues, people start to migrate from rural to the urban areas. The economic prosperity, better infrastructural facilities, relatively good governance and continuous rural to urban migration ultimately generate rapid urban growth along with urban sprawls, uneven population density, irregular growth of urban morphology as well as environmental degradation, etc. In modern urban research, Remote Sensing and Geographical Information System are used to monitor the growth and changing scenario of an urban area. Using sequential time-series satellite data land use/cover changes can easily be generated, which are essential for the assessment of urban growth. The present research deals with the pace of assessment of urbanisation, urban growth and land use/land cover dynamics of Agartala City through an integrated approach of Remote Sensing and Geographical Information System. Landsat Satellite imageries of two different time periods, i.e., Landsat Thematic Mapper (TM) and Enhance Thematic Mapper (ETM) have been acquired and quantified the land use/land cover changes in Agartala City during 1991 to 2015. The changing scenario of land use/cover of the city points out that Agartala has been gradually changing. The images of the study area have been categorised into five different classes, viz. built-up area, water body, open space, vegetation cover, and agricultural land. Spatially, vegetative cover and open space, a good part of low-lying marshy land and water bodies have been converted into built-up area in Agartala City. The study reveals that the city is expanding towards north-south direction due to the presence of the airport in the north and National Highway-8 along the periphery of the city in the south. The study also highlights the importance of digital change detection techniques to identify the nature and locational changes in the Agartala City area. It shall contribute to forecast possible future changes in growth patterns of the city as well as the development of sustainable urban land use planning decisions.

In this study, the metropolitan area of Delhi considered utilizing Landsat images from 1991 and 2011 in order to recognize changes to land cover. The changes in temporal land cover have an effect on the climate and its urban landscape. A change detection analyses the nature, extent of urban sprawl due to changes in land cover, land use/land cover (LULC) and twenty years of overtime change detection. This work explores the significant growth of the city at the expense of unbuilt land in its region. In the study area, there was a substantial land exchange between numerous LULC groups, not just because of the development of the city area. The accuracy assessment of the supervised classification showed good accuracy for 1991 and 2011 respectively, which was 96.31 and 97.35 percent. The twenty-year growth rate in the Delhi area was 11%. The study showed a dramatic shift in urban areas and agricultural land in Delhi and it contributed to 54116.2 hectares declining to 37243.17 hectares in 1991 and 2011 respectively.
Influence of Urbanization on the Land Use Change: A Case Study of Srinagar City
Urbanization has caused many impacts on natural resources associated with the reduction and conversion of green space. The land use/land cover pattern of a region is an outcome of natural and socio-economic factors and their utilization by man in time and space and has become a central component in current strategies for managing natural resources and monitoring environmental changes. Land Transformation is a process where changes in land use are observed at different time periods and is one of the important fields of human induced environmental transformation, with an extensive history dating back to antiquity. At present time, remote sensing and GIS are gaining importance as a vital tool for the analysis and integration of spatio-temporal data. The present study focuses on the land use land cover changes in Srinagar City for about 31 years (1979-2010) by the comparison of two satellite images of different dates and other similar information of the intervening years for quantifying the magnitude of land use/land cover change.
Land use/land cover (LU/LC) changes were determined in an urban area, Tirupati, from 1976 to 2003 by using Geographical Information Systems (GISs) and remote sensing technology. These studies were employed by using the Survey of India topographic map 57 O/6 and the remote sensing data of LISS III and PAN of IRS ID of 2003. The study area was classified into eight categories on the basis of field study, geographical conditions, and remote sensing data. The comparison of LU/LC in 1976 and 2003 derived from toposheet and satellite imagery interpretation indicates that there is a significant increase in built-up area, open forest, plantation, and other lands. It is also noted that substantial amount of agriculture land, water spread area, and dense forest area vanished during the period of study which may be due to rapid urbanization of the study area. No mining activities were found in the study area in 1976, but a small addition of mining land was found in 2003.
Monitoring Urban Landscape Dynamics Over Delhi (India) Using Remote Sensing (1998–2011) Inputs
Urbanization is increasingly becoming a widespread phenomenon at all scales of development around the globe. Be it developing or developed nations, all are witnessing urbanization at very high pace. In order to study its impacts, various methodologies and techniques are being implemented to measure growth of urban extents over spatial and temporal domains. But urbanization being a very dynamic phenomenon has been facing ambiguities regarding methods to study its dynamism. This paper aims at quantifying urban expansion in Delhi, the capital city of India. The process has been studied using urban land cover pattern derived from Landsat TM/ETM satellite data for two decades (1998–2011). These maps show that built-up increased by 417 ha in first time period (1998–2003) and 6,633 ha during next period (2003–2011) of study. For quantification of metrics for urban expansion, the Urban Landscape Analysis Tool (ULAT) was employed. Land cover mapping was done with accuracy of 92.67 %, 93.3 % ...

Cities are hubs of economic activity, innovation, and employment. People from rural areas migrate to cities in search of more diverse income opportunities. The increasing demand for space in cities puts pressure on urban land, resulting in urban built-up expansion. The immediate impact of urban expansion can be seen on the peri-urban outskirts, where land resources are being altered and converted from one use to another due to increased demand for urban land uses, particularly residential uses. As a result, this study examines urban expansion and changes in land use land cover in one of the fastest-growing urban centres in Western Uttar Pradesh, India. A GIS-based analysis approach was used for this. From 1980 to 2018, various satellite and analogue maps were used to map land use and land cover at various times. In ArcGIS software, a change detection technique incorporating a simple image differencing method was used for land use land cover change analysis. The findings indicate a significant increase in built-up classes over the last four decades. A significant amount of agricultural land was lost as a result of the expansion. There is a dissimilar pattern of landuse changes, with the change being most noticeable on the city's northern and eastern outskirts, which is a source of concern for city planners.
