2. Management of plant health and crop diversity –
a case study
Objective
• Specifying how a group
of seed producers
articulate crop diversity
and plant health
management
Methods
• Interdisciplinary
combination of field
trials, and qualitative
inquiry: interviews and
participant observation

3. Main result
Plant health is managed in
situ and conceived in amidst
the interactions between the
local environment, the
plants and the farming
practices.

• In situ management

diversityoffieldcornintheU.S.
Objective
• How do U.S. field corn
growers perceive,
monitor, and manage
crop genetic diversity
on their farms?
Methods
• Conducted a series of
in-person interviews
with Midwestern corn
growers about how
they monitor and
manage on-farm
genetic diversity on
their farms.

11. Monitoringon-farmgenetic
diversityoffieldcornintheU.S.
Main result
• Majority of farmers
interviewed rely on
seed dealers to make
variety decisions and
responses varied
drastically as to their
understanding of what
pedigree information
they have access to.

12. Monitoringon-farmgenetic
diversityoffieldcornintheU.S.
• If farmers do not have
access to the genetic
background details of
their seed and rely on
seed dealers’ variety
recommendations, who
is monitoring and
managing on-farm
diversity in U.S. fields?

a source of social
innovation for in-situ
management of
biodiversity?
Methodology
• Online survey

allies
• In-depth semi-directed
interviews with
identified stakeholders

15. MappingeuropeanCSAs’

Main result
• CSAs’ consumer
participation in seeds
production and
conservation is rare
• The initiatives on

are mostly initiated and

dissemination on landrace
varieties
• What impact of the institutional
environment on
• What impact on the network
dynamics and participation in a
context of growth
Methods
• IAD2 framework (Ostrom,
2005, 2009)
• Network structure
• Knowledge systems
• Governance and Rules-in-
use of the member groups
• Network formalization of
knowledge exchanges
between the groups
• Giuliani (2007) on innovative
wine clusters

27. Theroleofknowledgegovernance

Main result
• A polycentric and open
network covering
discontinuous territories
• A diversity of rules and
models of collective action
• With differentiated positions
of the groups within the
network
• The groups with the stronger
“knowledge base” are more central
• Size of the collection
• Type of activity
• Level of investment in
network seed activities

28. Theroleofknowledgegovernance
withpeasantseednetworks.
• Beyond seed exchanges: recreating
a shared knowledge base
• Different trade-offs between
distributed and locally centralized
models depending of the human
and financial (facilitator + €€€ )
• Against institutional
monocropping:
• Maintaining a diversity of models of
collective action
• A dynamic of mutual learning and
hybridization of rules

30. FromCosmopolitanmaizetoIdentitarianmaize
Objective
To analyze forms of
organization related to maize
landraces management.
To trace the construction of
new connections, narrations,
imaginaries on maize culture.
To identify motivations, values
and limitations related to
maize landraces management.
Methods
France – Italy Comparative
analysis based on:
• Semi-structured interviews
with 47 farmers
• 29 in Aquitaine
• 18 in Veneto
• Observant participation.
• Historical research.

31. FromCosmopolitanmaizetoIdentitarianmaize
• Aquitaine:
• maize landraces from Latin
America and from different
European countries
• genetic mixing
• animal feeding
• interest in having their “own
seeds”.
• Veneto:
• local maize form Veneto
landraces
• conservation "in purity”
• use for human food
• interest in typicity and
commercial valorization.
Varieties of maize landraces
Main reasons for growing maize landraces

32. FromCosmopolitanmaizetoIdentitarianmaize
• Different and often
opposite management
strategies between the two
maize collectives. These
different paths shaped
farmers’ approaches to
maize conservation and
breeding, as well as their
attachment to maize.
