Tomorrow’s formula for food production
• what we produce and consume
• how we produce and
• where we produce
– all under changing climatic conditions.

Agricultural & tree biodiversity is an important part of the solution
• Provides diverse nutrient content and dietary diversity through many available species and varieties within a species.
• Provides more crop options to buffer against extreme climactic events.
• Allows farmers to limit the spread of pests & diseases.
• Sustains soil health, food & habitat for important pollinators and natural pest predators.
• Provides variability to adapt to different edaphic conditions.
• Source of genetic material vital for future generations.

• Controlling for # socio-economic factors including GNI, trade, infrastructure,..
• size of bullet = GNI per capita
• Low diet diversity in Ethiopia is also well reported on at individual and household level (e.g. Headey 2014, Hirvonen et al. 2014)

In marginal areas, tailored solutions are required
• 18.4% of farmers varieties are superior to the best improved variety for maturity
• 31.4% of farmers’ varieties are superior than the best improved variety
• A yield advantage of 61% obtained from the best landrace over the best improved variety (Robe) and 23.9% of the farmers’ varieties were showing a yield advantage

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
New business model needed: more consumers, producer and location specific; more co-creation
