Role of Major Forest Biomes in Climate Change Mitigation: An Eco-Biological Perspective

The rapid alteration in the global climate due to anthropogenic activities has profound eco-biological impacts, which invariably affect the ability of natural communities to effectively perform ecosystem services. The eco-biological impacts could be viewed across various dimensions including loss of biodiversity as well as ecosystem goods and services, changes in phenology, prevalence of droughts and forest fires, disease outbreaks, reduced crop yields and increase in intensity and frequency of extreme weather events. Although, the natural ecosystems are innately endowed with the ability to maintain homeostasis by means of resistance and resilience, this ability to cope up is severely impacted by various other factors like deforestation, habitat fragmentation, land-use change and biological invasion, which exacerbate the effects of climate change. The eco-biological impacts of climate change are tied with socio-economic aspects by means of market values of the produce, poverty, undernourishment, livelihood security, etc. At this crucial juncture, forest biomes offer an immense ecosystem service towards climate change mitigation through carbon sequestration. Nevertheless, the three major forest biomes, viz. tropical, temperate and boreal, with their unique characteristics, vary in their response to climate change as well as mitigation potential and response. This review chapter aims to understand the varied climate change impacts and the crucial roles of major forest biomes in climate change mitigation and their various ecological services to formulate better forest management strategies.
