In summary
• ICT generate more and more data
• Data are going social
• Big Data is about “repurposing” in many different ways
• Dumb force of big n obviates precision, long waits and big

4. Farmers test and report back by mobile phone
2. Each farmer gets a different combination of varieties
3. Environmental data (GPS, sensors) to assess adaptation
1. A broad set of varieties is evaluated
6. Detect demand for new varieties and traits
5. Farmers receive tailored variety recommendations and can order seeds
