Global Climate Change and Inland Open Water Fisheries in India: Impact and Adaptations
India has crossed the fisheries production of 10 million tonnes in 2015 and presently on its way to achieve the second blue revolution. Among all the major factors impeding sustainability of fisheries, factor of climate change is the recent addition. Climate change trends along major river basins of India have revealed a warming trend (0.2–0.5 °C), declining rainfall (257–580 mm) and shifting seasonality of rainfall occurrence. Rising sea levels (1.06–1.75 mm/year), receding Himalayan glaciers and frequent occurrence of extreme weather events are also a matter as per IPCC AR5. The present article discusses the contributions made by ICAR-CIFRI since 2004 on climate change vulnerability assessment framework, changes in breeding phenology of fishes, models on fish reproduction and diversity, thermal tolerance of fishes, carbon sequestration potential of wetlands and indigenous climate smart fisheries adaptation strategies. In addition, understanding the response and adaptation capacity of fishing and fishers to the physical and biological changes have also been discussed in the chapter.
