  1. 1. Coping with heterogeneity. Typologies foragricultural research and developmentSantiago Lopez Ridaura (Pablo Tittonell)
  2. 2. What is a typology?The study, analysis or classification based ontypes or categoriesWhat are they used for in AgSci: Describe heterogeneity Simplify complexity Target technical innovations Develop organisational alternatives Aim policy measures Select collaborators for R&D projects

  5. 5. A structu-functional typology Farms in Camargue, South of France TYPE Brief descriptionSpecialized large size rice producer Farm size > 265 ha. Rice surface > 80%Specialized middle size rice producer Farm size < 265 ha. Rice surface > 80%Large size rice producer More than 60% of their surface under Rice, the rest in durum wheat, more than 276haMiddle size rice producer More than 60% of their surface under Rice, the rest in durum wheat, less than 276haPartially organic rice producer Same land use as middle sire rice producer but an average of 20% of LU in organicLivestock breeder Around 35% of rice, 35% of forages and 30% of other cropsOrganic livestock breeder Same land use as livestock breeder but with partial or total area in organicDiversified crop producer More than 50% of durum wheat and other crops, an average of 35% of riceOrganic diversified crop producer Same land use as diversified crop producer but with partial or total area in organic
