Future Needs for Effective Model Applications James W. Jones

This symposium explores the users, model capabilities, data availability, and other key issues related to effective model applications in crop modeling. It discusses the applications, operators, and developers of models, as well as the data accessibility and availability. The symposium also highlights the importance of addressing policy, management, and scientific issues in crop modeling. It presents tools under development and opportunities for interdisciplinary research and integrated crop modules.

  2. USERS • Applications for what? • Who will operate the models? • Developers • Researchers • Advisors to: • Farmers • Policy makers • Industry • Farmers • Automatic Operation? Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  3. Model Capabilities • Actual Yield • Tillage • Pests & diseases • Spatial variability influences • Low inputs • Changes in soils • Environment effects, sustainability • Complex cropping systems (space, time) • Genetic X Environment interactions • Address policy, management, & scientific issues Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  4. Data Availability, Accessibility • New measurement methods (e.g., precision agriculture, remote sensing) • New capabilities for data access (e.g. Internet) • New types of data (e.g., genomics) • New technology for processing data (e.g., GIS, optimization techniques) • Balance model capabilities and input needs with data availability – need to continually reassess to match our knowledge with capabilities to apply it – where it is needed Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  5. Other Model, Data Issues • Intellectual Property Rights • Modularity for efficient development • Data standards for applications Nowlin Chair Crop Modeling Symposium November 10-11, 2000
