Outline
• What is the problem? • Integrated information resources • Web & GIS Tools • Achievements • Some technical challenges
Stem rust Puccinia graminis f. sp. tritici
What are the problems ?
Farmers saved worldwide over US$1 billion annually for more than four decades.
Global Cereal Rust Monitoring System
• Surveillance: Where, what, how much, change in time and space • Monitoring : Pathotyping, genotyping and phenotyping • Stability of resistance: What cultivars are attacked/not attacked • Population biology: Mechanisms and Evolution of (meta)
Populations of Puccinia
• Farming community: Avoid severe epidemics (operational decisions) • Breeding community: Strategies for breeding of resistant cultivars • Scientific community: What’s new, system analysis • Political: Food security, Strategic and tactical decisions
Food security in developing countries
Durable Rust Resistance in Wheat
Durable Rust Resistance In Wheat Led by Cornell University $40.000.000 Phase II: 2011-2015
Host Pathogen Dbase (survey, virulence, pathotypes, Trap Nursery,
Barberry, DNA diagnostics)
User Management
Quality control/ management/publish
Data Export / Exchange
On-line Data Entry
External Applications e.g., RustMapper
Outputs: Maps, tables and graphics e.g. Survey mapper and Virulence mapper
NB: Generic - Applicable to all rusts & other diseases
Smartphone / tablet survey tool
Data Management: Wheat Rust Toolbox
SQL Databases: Host-Pathogen etc.

• Landscape-scale models for disease spread • Stochastic models: allow for uncertainty and
variability • Coupling meteorological with epidemiological
models to predict: – Risk – where might the pathogen arrive? – Hazard – likely rates of spread if the pathogen arrives? – Control – ‘what if’ scenarios
Epidemiological toolbox

Achievements Integrated Information Resources - and ICT framework well established
Global data collected in dedicated structured databases, use of standard
methods, network of expert labs, quality control, “on-the-fly” dissemination on several information platforms.
Consequently, more robust conclusions, stimulate data contribution and collaboration between partners and users
35 Countries participate in surveillance - 25% of global wheat area
8 members of the Ug99 race group identified – we know what they are, where they are and where they (most likely) are heading!
BGRI: Introduction of Stem Rust resistant cultivars in risk areas on the track
Europe: New exotic rusts are spread by the wind from Asia to Europe. The Global Rust Reference Center and its network of partners are prepared to analyse it in a global context
Some technical challenges Info group (databases and web tools) joined with the GIS group Web based & dynamic GIS applications. Enable the analysis and integration of diverse and “big” data
Wheat Rust Toolbox Google maps / KML files has limitations . Search for AU GIS
server solution Exchange of data and integration between ICT platforms /
SmartPhone & Tablets Integration with Apache server at AU IT for the operation of
R-statistical components (e.g. Statistics and Phylogenetics) Keep up with new technologies Do not develop huge, nonflexible IT systems
Thank you for your attention!
