1Values and Variables identifying the critical
variables in linked social-ecological systems.

2This presentation.
- Demonstrates numerical taxonomy as an approach to
identifying critical variables that define
difference between people in the values that
underpin decision-making in landscape management - Ecological sampling
- Conceptual models
- Focus on numerical taxonomy to locate statistical
tensions as insight into interactive processes
3Landscape managementcritical issues
- Resilience
- emerges at the complex interface between social
and biophysical systems - Complex assemblage
- of relationships, values and practice
- Symbolic relationships
- with place and between people drive rational and
material decisions - We need to identify these relationships and
values - to manage for adaptive and resilient
agricultural landscapes
4Numerical Taxonomy
- Meta-theoretical shift
- from inferential analysis
- Robust and statistically evaluated
- Process based portrayal
- of structure
- Characterisation
- of sets of cases variables
- Emphasis on
- diversity not reduction
- Non-normal distribution of data
Byrne 2002, Belbin et al 2002.
5Ecological sampling
- Sampling across social catchments to capture
- Broad representation that accurately reflects
diversity in the population base - Population statistics
- Land-use
- Geographical range
- Representation that reflects the decision-making
community - Captured
- critical

6Scale people and the landscape
- Continuum
- The abstract environmental space of
representation across a range - Captures the diversity of interacting processes
- Sets the boundaries for the context
- Community
- Reflects the context within a specific landscape
- the pattern of variables that represent a
particular landscape context - Describes the content of a landscape context
Austin, 1991
7The decision-making community
- Conflict
- Cognitive
- People have different definitions and judgements
of a situation - Values
- Goals and outcomes are in dispute
- Interest
- Relative cost and benefits of a situation
- Relationship
- The winners and losers in the exercise of power
- Three forms
- Status Quo
- Subjugated
- Subject
- Two interactions
- Captured
- Critical
Duane 1997, Guattari 2000, Winter, Winter 2000
8Defining the community
- Communities of place
- Are tied to a physical space through geography
- Communities of identity
- Tied to each other through social characteristics
but may transcend place - Communities of interest
- Commonalities in how they relate to a particular
ecosystem or resource as beneficiaries of the
place or contributors to its condition.
Duane 1997
9Linked dimensions
- Sense of place
- natural environments can be viewed both as
ecological systems subject to the laws of natural
processes and as socially constructed places - Social Capital
- Social structure, process and organisation
providing resources (environmental, cultural,
ethical, economic and spiritual) for individuals
to realise their interests - Discourses of the Environment
- embedded in language.that. rests on
assumptions, judgements and contentions

14Numerical Taxonomy the process
- Cluster analysis
- Affinities between cases and variables to define
groups - Social assemblages
- Attribute clusters
- Ordination
- a compact summary of the data reduce dimensions
- Co-ordinates of cases with variables in abstract
dimensional space - Network analysis
- relationships between participants and values
- Principal Axis Correlation
- linear correlation between variable ordination
- MonteCarlo Permutation tests
- significance of association between variables
ordination. - ANOSIM
- Statistical difference between clusters
- Kruskal Wallis
- variables most significantly associated with the
cluster analysis

23Content Process
- Sense of Place three sets of values
- Social, symbolic and economic
- symbolic values underpin social and economic
values - Social Capital micro, meso and macro scales
- Meso scale social capital facilitates bridging
social capital - Environmental Discourse ideals, ideology
practice - local, scientific and indigenous knowledge
- interacts with notions of truth and the exercise
of power to form the prevailing constraining
discourse
24Process System
- Complex Adaptive Systems
- Adaptive capacity
- Ability to self-organise
- Defined by emergent characteristics
- Emergent Characteristics of three interacting
social dimensions - Communities of Place, Identity and Interest
- Local, Scientific and Indigenous knowledge
- Social, Ecological and Economic landscape values.
