43 Symposium--Climate, Management and Topography Impacts On Vegetation, Soil Carbon Sequestration and Soil Erosion: A Tribute to Dr. Jerry Ritchie

Oral Session
A03 Agroclimatology & Agronomic Modeling

Dr. Jerry Ritchie made important contributions to the quantification of erosion processes through measurement of radioactive compounds in the landscape. This work was extended to measurement of carbon sequestration and analysis of erosion effects on topography. His work also involved use of remote sensing to evaluate vegetation cover change and desertification in rangeland landscapes. This research has contributed greatly to our understanding of vegetation cover changes, soil movement and carbon sequestration in the landscape as affected by topography, soil cover, climate and management. The ability to quantify soil carbon sequestration at landscape scales and control and quantify erosion is of paramount importance to maintaining food security and developing carbon management strategies. We invite authors to present papers on these topics and contribute to the symposium.
