Hypotheses
• Human-induced climate change is a totally newchallenge to the human kind– It requires changes in the way of thinking and
acting
• How to develop an effective strategy to respondto CC in an adaptive way?– Key words: reflection, learning
– Stakeholders: actors, owners, customers…• what role for researchers, engineers, policy makers,
consumers…?
• Structural coupling and science/policy interfaces

How we understand climate change?
• Complex
• Unintended consequences
• Multiple stakeholding
• Multiple scales
• Highly contested(Collins et al 2011 Env Pol Gov)
‘Do we have a shared
conceptual understanding of what
global warming is?’ (Brooks, 2005)

CC situations as wicked issues(Australian Public Service Commissioner, 2007)
Tame problem Wicked issueStable, well defined problem
clear when a solution is reached,
targeted actions can be designed
No definitive formulatio
actions relying on perceived evidence are
late and ineffective
Solutions can be objectively
evaluated as right or wrong
depending on targeted achievements
Contextualized “better” or “worse”
solutions (actions) emerging from
process quality assessment
solutions can be tried and
abandoned
Every action is “one-shot operation”:
Can be classified and approached
with tools already tested elsewhere
Every problem is unique and symptom of
other problems in specific contexts
The choice of explanation modalities
determines the nature of the problem’s
and the response pathways7Combining modelling and social learning for CC adaptation – PP Roggero

Systems view of CC in agriculture
• Complexity emerging from multiple perspectives:
– variety of time and space scales, cropping systems,
environmental socio-economic contexts
– variety of actors, responsibilities,systems’ perspectives
• Sharing the nature of the issue is crucial for
concerted actions towards sustainability– Quantitative tools essential, but not sufficient to address the
challenge of adaptive responding to CC
• Research results to provide tools for learning

Adapting WITH change
• A concerted action for a desirable performance
– …changeing with players under the same sheet music
– As in a jazz orchestra, the band continuously adapts to
soloists…
Ison, 2010, Systems practice: how to act in a climate change world, Springer
15
Adapting WITH CC
• In agriculture, the performance emerges from the
interaction of three components:– The biophysical system’s dynamics (eg climate, soil, crops)
– The social system’s dynamics (eg farmers practice)
– The structural coupling of the two that co-evolve and influence
each other
Ison, 2010, Systems practice: how to act in a climate change world, Springer
interface (norms, institutions,
technologies, measures…)

Framing research on CC
Business as usual Strategic changeSet targeted states to be achieved
through best practices under
“command and control” regulation
Contextualize actions and tools
towards improved performance
under changing contexts and
address self-organized systems
Delegate targeted projects to
experts to design effective
solutions through rules and
incentives
Invest on co-learning spaces,
remove barriers, promote volunteer
habits and response-ABILITIES
Farmers as users of scientific
knowledge produced by
researchers
Farmers and researchers as co-
producers of “hybrid knowledge” (Nguyen et al 2013)

Dairy sheep farmers’ perceptions of climate impacts
• Indicator of winter temperature: daily milk production– Winter less cool now than in the past (less frost)
• Uncertainty of autumn pasture availability– date of the first rainfall after summer– difficulties in seed bed preparation for the annual forage crop
cultivation in rainy autumn (mainly with high stocking rate)
• Uncertainty of complementary forage resources availability from annual forage crops– spring rainfall is critical to hay production to address autumn
pasture uncertainty

Farmers’ response to
climate variability
The majority of farmers have already responded to perceived CC
46
Actions already taken Actions farmers think to take
• Change/diversify crops
• Improve irrigation systems
• Improve animal health: veterinary
services, hygiene in stables
• Change/improve the animal diet
• Follow daily weather forecast to
support actions on the spot
• Do nothing (8%)
• Improve infrastructure (farm
structure, stables, barns, sheds)
• Adopt new technologies (i.e. air
conditioning systems for animals)
• Improve water use efficiency at
farm scale
• Interact with technical advisors,
researchers, neighbors
• Participate to social networks to
enhance adaptive capacity

ms - Reduce water consumption
- Use conservation tillage- Improve new grazing areas- Improve forage self-supply- Change forage system: more
grassland less arable crops- Strengthen integrated agro-
forestry-pastoral system - Recognize the role of
graziers as landscape managers
- Support maintainamce of permanent grasslands
- Support to farms’ structureimprovement
- Improve advisory services- Link complementary districts to
exploit forage resources: encourage pro-active farmers, participatory approaches
- Investment in co-research with farmers on CC adaptation practices

DiscussionType 1 scenario: Individual adaptation
(each farmer for himself)1.1. “Proactive”Self-establishment of adaptation practices:Increase farm size, invest on hi-tech (e.g. dairy cattle farms)
RisksEnvironmental pollution
Costs of water and energy are perceived as additional pressures
1.2. “Passive”Increased uncertainty (e.g. because of no anticipated adaptive responses)
Few investment in technologies and improved farming practices ( eg sheep)
RisksAbandonment of large grazing districts

DiscussionType 2 scenario: collective adaptation
(all SH for all farmers)2.1: “Bottom-up”Collective adaptive responses, Hi-tech farms (e.g. dairy cattle) will continue to develop (e.g. increase farm size, diversify crops, investment in technologies…);
Low-tech farms (e.g. some dairy sheep) can be also sustained and improved.
Opportunities: more investments in research on specific farm-level adaptation practices e.g. bio-fuels, waste water treatment, irrigation mgt...
2.2. “Top-down “ a. Effective policy measures: Hi-tech farms will growLow-tech farms sustained, no changes
b. Inadequate policy measures : Hi-tech farms rely on endogenous adaptive capacity Low-tech farms risk to disappear.
Assumptions:No long-term adaptation developed, no multi-stakeholder participation to the design of RDP measures

Conclusions and Implications
• Adaptation scenarios depend on different ways and attitudes in looking into the future – Perceptions of CC and impacts
– Investments on endogenous adaptive capacity (lay knowledge, skills, experiences, etc.) and exogenous driving forces (science, incentives, resources, etc.)
• Combining modelling with social learning was effective in generating credible scenario analysis (Nguyen et al 2013)
