H046:
Ecohydrology and Biogeochemical Processes in Savannas and Woodlands





Session ID#: 24284

Session Description:
Savannas are comprised of trees and grasses and are globally important ecosystems that sustain the livelihoods of a large proportion of the world’s human population. However, due to overgrazing, fire suppression, elevated atmospheric CO2, and climate change, savannas have experienced the proliferation of woody plants during the past century and have a tendency to convert to woodlands. Given the geographic extent of savannas, this conversion has important implications for biogeochemistry and eco-hydrology at local, regional, and global scales. The variety of feedbacks and connections existing between the major components of biogeochemical cycles and key aspects of hydrologic processes are expected to be altered by the conversion of savannas to woodlands, but these remain poorly understood. A comprehensive assessment of the joint impact of woody encroachment on biogeochemistry and eco-hydrology is essential for empirical and modeling researches aiming at understanding the dynamics and services of savanna ecosystems.
