Climate change has emerged as the most pressing global challenge of the 21st century and it has a dramatic effect on natural ecosystems and environment. Intelligent mitigation strategies to minimise climate change impacts can result in advanced, novel technologies; healthier aquatic ecosystems and higher food security and well-being for humans. The book includes 45 Chapters by expert authors, covering (i) Hydrometeorology and hydrology, (ii) Natural hazards and disaster risk management, (iii) Aquaculture, (iv) Changing biodiversity scenarios, (v) Capture fisheries, (vi) Food and nutritional insecurity, (vii) Climate change and socio-economic scenarios, and allied areas. It is hoped that this volume will further our understanding and research achievements in the field of climate change and its consequences and facilitate the synthesis of information on how climate-related changes will influence oceans, marine and inland ecosystems, hydrological cycles, fisheries and aquaculture and coastal communities and will be immensely useful to planners, scientists, conservationists, environmentalists, academicians, students and all those who are directly or indirectly involved in the study of impact of climate change and mitigation measures
