Book excerpt: This book discusses population growth and the resultant problems, and highlights the need for immediate action to develop a set of planned satellite towns around Indian megacities to reduce their population densities and activity concentrations. It addresses problems like unplanned spatial expansion, over-concentration of populations, unmanageable situations in industrial growth, and poor traffic management, concluding that only megacities and their satellites, when planned properly, can together mitigate the urgent problem of urban concentration in and around the megacities. Identifying the general problems, the book develops a quantitative and spatially fitting regional allocation model of population and economic activities. It also offers a policy-based planned program of development for the selected megacities in India along with their satellites and fringe areas to ensure a healthy, balanced and prospective urban scenario for India in the coming decades.
