The book explains in detail the concept of health and wellbeing. Health geography has its crux in spatial distribution of various geographical phenomenons influencing multiple aspects of human health. The book thus discusses the aetiology of human health. It also elaborates on human development processes and their impact on environment and human health. The book tries to put forth the spatial epidemiology of communicable and non communicable diseases in India and the world, based on authentic published sources of national and international organizations. The book devotes one full chapter on types of mental health and their prevalence in the world based on authentic sources of information. The last chapter of the book talks about Global Health Organizations and agencies. It also discusses Healthcare system in India, its merits and drawbacks. The geographical variations generate complexity in understanding cause and effect relationship between environment and human health. The book thus is organized in a simplified way and tries structure the complex aspects for the readers. I hope readers get benefitted from the book and get encouraged working on one of the most dynamic and extremely relevant theme of Geography of Health.
