"Models in Geography" aim at presenting the important models and theories in human geography at one place in a concise and cogent manner. These include System Analysis, Malthusian, Marxian and Demographic Transitional Models, Central Place Theory of Christaller and Losch, von Thunen Model of Agricultural Land Use, Weber??s Theory of Industrial Location, Rostow??s Stages of Growth, Heartland and Rimland Theories, and Laws of International Boundaries and Frontiers. Besides, the Limits to Growth and Laws of Migration have also been examined. A full chapter has been devoted to types and patterns of rural settlements, primate city, rank-size rule and models of urban land. Documented with the latest data, maps and diagrams, one chapter has been written on climatic change. It is hoped that the book will be of immense help to the students and teachers alike. This will also be useful for those preparing for various competitive examinations.
