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

In summary

• Many caveats apply

• Big Data is on the Peak of Inflated Expectations

• There is a Plateau of Productivity ahead!

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
