ABSTRACT
Climate change is one of the biggest environmental threats facing the world, potentially impacting food production and security, sustained water supply, biodiversity and natural ecosystems, human health and settlements. Food fish production, as is the case in all other primary production sectors, is expected to be influenced and or impacted to varying degree by climate change in different parts of the world. Most models on Global climate change indicate that the mountain snow packs are likely to decline in the west, which would bring adverse impact on fish populations, hydropower, water recreation and water availability for agricultural, industrial and residential use. All aquatic ecosystems, including that of freshwater are influenced by climate change. The North-Eastern (NE) region is expected to be highly prone to the consequences to climate change because of its geo-ecological fragility, strategic location vis-à-vis the Eastern Himalayas and international borders, its trans-boundary river basins and its inherent socio-economic instabilities.
