Climate change is a pervasive and growing global threat to biodiversity and ecosystems .Climate change impacts are extremely effect on plant productivity by reducing water use efficiency, increase salinity, high temperature stress and disturbing the soil health. Climate change also affects biodiversity by changing the behavior, morphology, and phenological by reducing species abundance, distribution and biodiversity loss. Climate change impact on human wellbeing is measured by the ecosystem services alteration caused by climate-related biodiversity change. The Ecosystem services have vital play an important role in the balance of the natural ecosystem and social-economic development, are suffering from degradation caused by human activities and climate change.
