Part 1: Rangeland management considerations under future climate change
Julian Reyes will describe the current state of process-based modeling in rangeland ecosystems including a discussion on what models are, why they’re useful, and how they can be improved for decision-makers. Specifically, Julian will detail the Regional Hydro-ecological Simulation System (RHESSYs) model and what improvements he has made to simulate grasses. As part of Julian’s dissertation, he will also explain how this can be used to inform rangeland management.
- Understand how models are being developed and applied to study environmental change in rangelands
- Be familiar with RHESSYs model data inputs and general approach to simulating grassland ecosystems
- Learn about projected climate change impacts to Northwest US rangeland systems
Part 2: Climate change, irrigation efficiency and water availability for agriculture
As climate changes, droughts are projected to become more severe and more frequent. Farmers are expected to adjust their management practices (e.g. investment on more-efficient irrigation systems) to reduce the negative consequences of droughts. In this webinar, Keyvan Malek will introduce a modeling platform to simulate farmers’ responses to climate change and investigate how different scenarios of climate change, crop type and initial irrigation system affect investment decisions.
- Understand the range of possible management responses to drought in Northwest agricultural systems
- Become familiar with how crop models are developed
- Learn about how crop and climate impacts models can help producers plan for investment decisions
Julian Reyes is a PhD Candidate in Civil and Environmental Engineering at WSU in Pullman. His research looks at the impacts of climate and management in rangeland ecosystems using eco-hydrologic modeling. He earned his B.S. in Civil Engineering in 2010 from WSU. During his graduate studies, Julian left the Palouse for one year to conduct research in Bonn, Germany on a Fulbright Grant. Later, he completed a science policy fellowship at the U.S. Global Change Research Program in Washington, DC through an NSF IGERT program linking nitrogen science and policy. Julian is currently a Fellow with the USDA Climate Hubs Program, and is based in New Mexico.
Keyvan Malek is a Postdoctoral Research Associate at Washington State University. He recently completed his PhD in WSU’s Department of Biological Systems Engineering. Before coming to Pullman, Keyvan studied Irrigation and Drainage Engineering in Iran and worked for several private water engineering companies. His research interests include the development of modeling tools, simulation of irrigation processes, climate change impact assessment, and economic analysis of farmers’ adaptation strategies.
