Synopsis Urban induced climate change has become the key global issue in the recent years. Urban land use and cover changes are the main driving force of such changes. This is a complex and difficult task, mainly due to the scarcity of observations and tedious computational requirements. The recognition in the 1990s that air pollution is a key global key issue as well as the lack of data available to investigate fundamental processes occurring in the troposphere led the scientific community to call for a worldwide effort to address pressing issues. The book is an outcome of the research programme addressing above issues taking empirical evidence from the metropolitan cities of India. The book adopts a perspective to consider the critical problems and policy strategies for cities in the 21 century. The study attempts to evaluate a number of qualitative and quantitative techniques for integrated assessment together with the changing role of urban geometry of the cities in the third millennium. Combining an academic understanding with an empirical approach to the problems together with policy perspective in the Indian metropolitan cities, its is useful for students, researchers, and teachers coming from urban studies, town planning, atmospheric sciences, environmental studies, geography, technology and policy science.
