1:10 PM Vulnerabilities Due to Climate on Water Supply
Jenny Adam, Sonia Hall, Civil and Environmental Engineering WSU
We will examine the long-term water supply and demand forecast for the Columbia River Basin as a whole, with an emphasis on eastern Washington. The vulnerability of meeting future water needs to climate change will be examined and compared across watersheds.
1:35 PM Netting for Hail and Sunburn Prevention

3:30 PM Closing and Pesticide Credits
Christopher Adams an Assistant Professor of Tree Fruit Entomology at the Mid-Columbia Agricultural Research & Extension Center in Hood River. His lab is focused on pests of pear and cherry including our current invasive species, spotted wind drosophila (Drosophila suzukii) and the brown marmorated stink bug (Halyomorpha halys). Other projects include the understanding the ecology and control of the leafhoppers that vector the phytoplasma responsible for cherry X-disease, and the landscape ecology and biocontrol of pear psylla.
Kirti Rajagopalan is part of the Land, Air, Water Resources, and Environmental Engineering emphasis area of the Department of Biological Systems Engineering at Washington State University. Her modeling group develops and utilizes a variety to modeling approaches to better understand and manage water and agricultural resources. The group focuses on trans-disciplinary efforts to problem solving and works closely with colleagues from a broad range of disciplines including engineering, economics, entomology, physiology, statistics, and agronomy.
Rob Curtis is a Research Entomologist for WSU at the Tree Fruit Research Center in Wenatchee.
Rebecca Schmidt-Jeffris, Research Entomologist USDA ARS. Her lab focuses on biological control of arthropod pests of tree fruit, including apples, pears, and cherries.
Tianna DuPont is a Tree Fruit Extension Specialist. Her work focuses on helping growers understand and apply research based solutions for tree fruit pests and pathogens.
Ken Johnson is a Professor of Plant Pathology with Oregon State University. His recent work has focused on control of fire blight in pear and apple and area for which he is world known, as well as epidemiology of blackberry rust, rapid detection of bacterial pathogens on seeds and flowers, and utilization of systemic acquired resistance for enhancement of plant health.
Jennifer Adam is the Berry Distinguished Professor in the Department of Civil & Environmental Engineering at Washington State University. She received her graduate degrees in Civil Engineering at the University of Washington, and her undergraduate degree at the University of Colorado.
