Impact of climate change on the ecosystem of the central Himalayas, Nepal
Abstract
The threats of climate change are found in both developed and developing countries. Since the impacts of climate change are global, irreversible, and pervasive, it is gaining worldwide attention. High mountains are the first indicators of climate change. However, the idea of what causes climate change effects on multiple ecosystem services remains scattered. This article is meant for information regarding the impacts of climate change on the ecosystem of Nepal. The result shows that climate change causes tree line shifting, change in land cover, extinction of species due to loss of habitat, imbalance in carbon sequestration on the terrestrial ecosystem while eutrophication of water bodies and extinction of endemic fish species was reported from the aquatic ecosystem. Tropical area is considered to be more affected by climate change in terms of Natural disasters and Health impacts. Moreover, different types of ecological modeling can be simulated in the context of Nepal for the prediction and future analysis of the impacts of climate change in the Ecosystem. Therefore, the impact of climate change is crucial and challenging.
