This book discusses disaster psychiatry and the impact of climate change in South Asia. South Asia consists of eight LMICs. As a region, it is one of the most disaster-prone areas of the world. Besides the increased frequency, disasters affect a large number of people in this area, as it is densely populated. Impact of the disasters is also considerably higher considering the scarcity of resources in the area. Recent studies identified that LMICs are more affected by climate change than high-income countries. However, little we know about the mental health impact of frequent disasters like cyclones, river erosions, droughts, floods, tsunamis, and the long-term effects of climate change in South Asian countries. Mental health consequences of the disasters are not contained within the immediate post-disaster period, rather it continues long-term. Ironically, despite the population affected being usually large, the information about the sequelae is really scant. In addition, the support systems and resources for the survivors are not as robust as in the developed world. It appears that the enormity of the concerns is not appreciated by the authorities in these countries, primarily because of a lack of information and inadequate or ineffective professional suggestions. While the challenges continue, many survivors with mental health problems secondary to disasters are not recognized, treated, or rehabilitated appropriately. There is an urgent need to emphasize these aspects, especially in the South Asia region, considering its enhanced vulnerabilities.
