Evaluating system-level strategies for successful variety delivery and regional pest/disease management
Impact network analysis (INA) is one of 11 valuable tools in the CGIAR RTB Toolbox, a set of effective, low-cost methodologies designed to strengthen seed systems for roots, tubers and banana crops.
INA helps project leaders and policymakers evaluate and design system-level strategies for successful delivery of improved crop varieties and regional pest and disease management.
This event will feature an introduction to INA including several examples of its successful use around the world and how users may use this tool with software in R.
