6. Aims and introduction Introduction
Research questions
Is agrobiodiversity randomly distributed at the local scale ?
Do some farmers contribute significantly to the global
agrobiodiversity ?
Is seed circulation at random among farmers ?

8. Team and disciplinary scope Disciplinary scope
Disciplinary scope : an interdisciplinary challenge !
Social and Human Sciences : anthropologists, geographers, ethnobiologists
Plant Sciences : ecologists, geneticists, agronomists
Our differences:
• Vocabulary
• Research questions
• Fieldwork methods
Our common interests :
• Agrobiodiversity
• Seed circulation
• Network analysis

Conclusions
1 Crop diversity is not distributed
at random
2 Some farmers contribute
significantly to the global
diversity

10. Major outcomes New insights
New insights (2/2) : seed circulation
Conclusions
1 Crop circulation is not at random
2 Actor status and biocultural properties of plants impact network
characteristics

11. Major outcomes Key achievements only possible through the synthesis approach
Key achievements : “meta-knowledge”
Acquisistion
Creation of a collective thesaurus to characterize seed circulation
