Remote Sensing and GIS-Based Monitoring of Land Use Change in Nagpur District: Insights and Implications Tauseef Ahmad Ansari, Dr.Wael Albawwab Assistant Professor1, College of Engineering, University of Buraimi, Oman.

However, accurately assessing changes in land use and land cover over short periods of time presents significant challenges. The city of Nagpur has experienced rapid development, characterized by large-scale infrastructure projects that have negatively impacted various hydrological parameters. This research paper investigates the spatial and temporal changes in land use within Nagpur District between 2002 and 2016. The findings indicate a notable increase in built-up areas and fallow lands, spanning approximately 10 to 47 km2 and 164 to 2063 km2, respectively. Conversely, there has been a reduction in crop lands, forest lands, and water bodies, ranging from 57 to 2372 km2, 112 km2, and 189 km2, respectively. Water bodies have also witnessed a decline ranging from 19 to 74 km2. These findings underscore the necessity for effective urban watershed management practices to safeguard the hydrological parameters in the region. Key Words: Land Use/ Land Cover, Remote Sensing and GIS, Urbanisation, Nagpur District.
Introduction: Land use and Land cover (LU/LC) are critical components that shape the dynamics of the environment. They refer to the classification and distribution of various land types and their associated characteristics. The process of urbanization, driven by factors such as population growth and economic development, has a profound impact on LU/LC patterns and, consequently, on hydrological parameters. LU/LC serves as an essential indicator of catchment area characteristics, influencing the hydrological response of a region. Changes in land use, especially in urban areas, can significantly alter the natural hydrological cycle. Urbanization typically involves the conversion of natural landscapes, such as agricultural fields, forests, and water bodies, into built-up areas, resulting in increased impervious surfaces and reduced infiltration capacities. This transformation leads to changes in surface runoff patterns, increased flood risks, altered streamflow regimes, and modifications in groundwater recharge rates. The scientific investigation of LU/LC changes and their hydrological implications is crucial for understanding the impacts of urbanization on water resources. Several studies have investigated the relationship between urbanization and LU/LC changes. For example, research conducted by Samant et al. (1998) focused on Mumbai and highlighted the significant influence of population pressure on land use changes within the city. Similarly, Praful et al. (2011) examined land use transformations in the semi-arid region of Madhya Pradesh state, shedding light on the implications of changing land cover on local hydrological conditions. Another study by Sundar Kumar et al. (2012) investigated the drastic alterations in LU/LC that occurred in Vijayawada city between 1973 and 2009, providing valuable insights into the spatial and temporal dynamics of land use changes and their hydrological consequences. Sreenivasulu G. et al. (2013) utilized RS and GIS techniques to study LU/LC changes in the Vempalli area of Kadapa district, Andhra Pradesh, India, contributing to a better understanding of land use patterns and their effects on local hydrological resources. In one of the study by Pramod M. et al. (2014), the authors employed RS and GIS to examine land use changes and drainage patterns in Andhra Pradesh, India, facilitating the identification of areas susceptible to hydrological risks and the development of appropriate management strategies. Furthermore, Surya and Sumant (2016) conducted a district-wise analysis of land use changes in the capital city of India, providing comprehensive insights into the urbanization-induced LU/LC modifications and their implications for hydrological processes. In recent years, a growing number of scientists have embraced the use of remote sensing and geographical information systems (GIS) technology for investigating land use and land cover changes. Researchers such as Praveen et al. (2013), Santosh et al. (2015), Hassan et al. (2016), Gogoi et al. (2019), Prabuddh et al. (2019), Prem et al. (2019), Biswajit et al. (2020), and Joseph et al. (2020) have contributed to this emerging field of study. The detection and analysis of land use and land cover changes are typically accomplished by comparing different time period images and utilizing diverse datasets that provide information on specific land use categories. These datasets may include information on built-up
