Recarbonization of the Biosphere
Human activities are significantly modifying the natural global carbon (C) cycles, and concomitantly influence climate, ecosystems, and state and function of the Earth system. Ever increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands. However, land-based sinks require long-term management and a protection strategy because C stocks grow with a progressive improvement in ecosystem health.
Nobel laureates and renowned experts deliberate on the possibilities of managing the Earth-Human System for slowing-down atmospheric increases in carbon dioxide and for recarbonization of the biosphere The comparison of ecosystems and their role in the global carbon helps the reader in identifying challenges and opportunities to prioritize C sinks for managing recarbonization Includes interdisciplinary and transdisciplinary approaches for redistribution of C among biospheric C pools
