Summary

Spanning biophysics, biochemistry, land use change, and measurement and modeling, this book addresses the quantitative, spatial, and temporal dynamics of global savannas. It describes the global savanna biome in terms of their broad ecological properties, temporal dynamics, disturbance levels, and human dimensions. The text examines carbon, water, energy, and trace gas fluxes for major global savanna regions. It looks at quantitative surface properties of savannas that can be retrieved using remote sensing and numerical approaches used to explore savanna dynamics. The authors also explore how savanna modeling and measurement approaches might be unified.
