INTRODUCTION
1.1 GENERAL Urbanization is one of the most powerful and visible anthropogenic forces on Earth. Since the second half of the twentieth century, the world has experienced its fastest rate of urbanization, particularly in developing countries. Urbanization refers to the increase in population, density, or extent of cities over time. Dramatic urban expansion was found with similar degree of cropland decrease. Urban expansion caused evident environmental impacts on local runoff and water quality. This study allows to make informed decisions on environmental and resource management issues. Geographic Information Systems (GIS) is an powerful and cost-effective tools for assessing the spatial and temporal dynamics of LULC. Rapid urbanization has greatly accelerated economic and social development, and global cities are engines of economic growth and centers of innovation for the global economy, but urbanization has also created numerous environmental problems ranging from the local to the global scale, including increased air and water pollution and decreased water supply, local climate alteration and increased energy demands, insufficient housing and sanitation facilities and traffic congestion, and a major reduction in natural vegetation production and carbon storage. Thus, the identification and assessment of environmental impacts as a result of modern urbanization have become a top priority and many recent studies have been conducted with the goal of better understanding the impacts and issues related to urbanization.
1.2 OBJECTIVE OF THE PROJECT
The specific research objectives of this project are as follows:
To assess the demographic profile of Erode;
To assess the land use/land cover of Erode during 1990-2010;
To explore the characteristics of LULC changes and characterize the underlying driving forces in Erode City by making use of remotely sensed data and socio-economic information.
