  1. Future Needs for Effective Model ApplicationsJames W. Jones • Users • Model Capabilities • Data Availability, Accessibility • Other Model, Data Issues Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  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

  6. Toward an ICASA Toolkit Made possible by Data standards Modular development of models, components Data sets Willingness of scientific community to share How to operationalize? Internet, CD Distributed system

  7. Components of ICASA Toolkit • DSSAT v3.5 • Model Development and Training Tools (FSE/FST) • Data Sets for Model Testing - GCTE cooperation • Farm System Simulator • Yield Forecast Tools • Weather Generator, Data Manager • Crop Management – GIS DSS Tailored Products • Regional Planning Tool; Options for Development (MGLP) Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  8. Tools Under Development • Modules for crop models • Application tools (e.g., optimization) • Parameter estimation tools • Data sets for model development, testing • Decision support packages • farm • research • policy Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  9. Examples of Tools Under Development • Windows Version of DSSAT, Multilingual • Modules for Pests, Tillage, Organic Matter,... • Pasture Model • Watershed Management Planning Model • Other Crops (Cowpea, Pigeonpea, Pasture, …) • Climate Prediction Application Tools • Data Base Management, ICASA Data Standards • Farm Models with Livestock, Crop Enterprises • ... Nowlin Chair Crop Modeling Symposium November 10-11, 2000

  10. Evaluate Model Performance Disciplinary Research Process Models Evaluate Model Performance Data Bases (Soil, Weather, Crop, Genetic, Socio-economic, environment,… Interdisciplinary Research Research Data Impact Assessment Models (Regional, National) Integrated Crop Modules, Models Watershed Management Models Farming System Models Precision Ag Models Decision Support Systems Models, Modules of Livestock, Water Quality, Forests, Economics, … Crop Modeling Opportunities Nowlin Chair Crop Modeling Symposium November 10-11, 2000
