C08.24 Land Degradation and Desertification
Session: Land Degradation and Desertification in the context of Global Environmental Change: Management, Vulnerability, and Policy
Chair(s): Guðrún Gísladóttir & Paul F. Hudson
Abstract:
Managing land degradation and desertification is a pressing issue in the context of global environmental change. Developing effective policy and management strategies requires knowledge of a comprehensive range of physical and social processes and how they may be modified and adjust to anticipated global environmental change scenarios, including different manifestations of climatic change or sea level rise. The goal of this session is to bring together researchers interested in the management of specific types of landscape environments to cope with different forms of global environmental change along the lines of several interrelated questions: How is management being approached and what are the lessons learned? What types of physical modifications (engineering and earth works) are undergoing to cope with land degradation and/or desertification? What are the obstacles to effective policy for managing land degradation and desertification? We welcome a comprehensive range of topics including academic and applied scientists from universities and government agencies who work at the interface of land degradation and desertification, including land use management, agricultural policy and food security, soil erosion, change, flooding, risk analysis, and river and coastal zone management. The presentations will be further organized into appropriate themes depending on the range of topics represented within submitted abstracts. Publication of papers will be sought in an appropriate peer reviewed academic journal. Please contact Paul Hudson (pfh@austin.utexas.edu) or Guðrún Gísladóttir (ggisla@hi.is) with questions.

Session: Land Degradation and Geomorphology: Monitoring, Assessment, and Theory Development
Chair(s): Paul F. Hudson & Guðrún Gísladóttir
Abstract:
Geomorphology and land degradation science have a long and distinguished history of integrated scientific inquiry. Geomorphology, as a distinct scientific discipline, provides academic and applied scholars of land degradation with theoretical frameworks and methodological tools for understanding the origin, magnitude, and controls on land degradation and desertification. Geomorphologists increasingly play important roles in landscape restoration strategies, including conceptual and applied roles. This session seeks presentations that address the study of land degradation from all sectors of geomorphology, including hillslope (runoff and soil erosion), fluvial, coastal, and aeolian processes. We welcome contributions based on field, experimental, as well as theoretical modeling. Presentations will be further organized into appropriate themes depending on the range of topics within submitted abstracts. Publication of papers will be sought in an appropriate peer reviewed academic journal. Please contact Paul Hudson (pfh@austin.utexas.edu) or Guðrún Gísladóttir (ggisla@hi.is) with questions.

Session: Forest fire effects on soil-vegetation dynamics, erosion and land degradation
Chair(s): Lea Wittenberg & Paul F. Hudson
Abstract:
Fire is a vital control on the development of vegetation and soil characteristics, and influences processes of land degradation and desertification. This session seeks presentations that address the effects of fire on soil-vegetation dynamics, including hydrology, the development of physical and chemical soil quality, as well as soil erosion. We welcome contributions based on field studies, experimental results, as well as theoretical modeling. Presentations will be further organized into appropriate themes depending on the range of topics within submitted abstracts. Please contact Paul Hudson (pfh@austin.utexas.edu) or Guðrún Gísladóttir (ggisla@hi.is) with questions.
