Exploring the Role of Networks on Strategic Decisions Making of Pastoralist in Central Australia

  • Agsitment – Report
  • Adoption - Proposal
  • Collaborators:
  • Nick Abel, Art Langston
  • Ryan McAllister, Ian Gordon
  • Yiheyis Maru, Paul Box
  • 2. Yiheyis Maru, Paul Box,
  • Pip Pattison and Pascal Perez

Role of Networks on …
  • Purpose
    • Influence of social networks on strategic decisions of pastoralists
      • Agistment of cattle
      • Adoption of innovation
1 role of networks on agistment
1. Role of networks on Agistment …
  • Approach
    • Empirical data collection
    • Social network analysis & multi-agent based modelling
  • Data Collection
    • 84 pastoral stations; 68 pastoralists
    • Interviewed 19 pastoralists
    • Discussed with five key informants
    • Collected individual attributes, relational data and pastoral records

Statistical Network Modelling
  • QAP (Quadratic Assignment Procedure) model in UCINET (Borgatti et. al. 2002)
  • Exponential Random Graph (or p*) models in Pnet (Pattison et. al. 2005)

Family ties

Agistment ties

Friendship ties

Results

TABLE 1. QAP-CORRELATION COEFFICIENTS

At α=0.05 ‘p<0.05’, both family and friendship ties are significantly correlated with agistment network.

TABLE 2. REGRESSION COEFFICIENTS

TABLE 3. MODEL FIT

  • The R-square is significant but small.

Preliminary finding

Social network especially friendship ties play a significant role in mediating agistment practice. However, a lot of other factors are needed to explain the variability in agistment ties.

Further work

Parametric social network modelling (P* approaches)

Dynamic multi-agent and network modelling

Agent-Based Modelling

Can a model of land attributes and individual behavior reproduce the global picture?

Build from the bottom up …

the landscape...

  • 1 km2 square of land
  • Receives rain
  • Grows forage
  • Gets grazed
  • Property = collection of paddocks
  • Owner moves stock
  • Owner sells
  • Owner agists in or out
  • Paddock = collection of landscape pieces
  • Gets stocked
slide9

At what point does a pastoralist agist?

Different kinds of relationships between pastoralists create different weights of connections, affecting likelihood of agisting (or other practice)

  • Agisting is function of
  • Land condition
  • Available alternatives
  • Ability to agist
  • “basic philosophy”
  • Level of trust
2 role of networks on adoption
2. Role of networks on Adoption …

Why

  • Pastoralism is and will continue to be a dominant land use in Australia
  • The success of pastoralism will significantly depend on adoption of innovative ideas, technologies and sustainable management practices by pastoralists.
slide11

Most studies are on:

  • attributes of innovations
  • characteristics of individual pastoralists .

Farm

households

Sustainable

practices

Networks?

Little on the role of pastoral networks on adoption

the role of network and adoption
The role of Network and Adoption…

Indications of social costs

  • Pastoralists that have ‘gone green’ do so facing the disapproval of their peers (Richard et al. 2003)
  • Similar observation in our study

General proposition

  • Networks among pastoralists may play a significant role in filtering and reinforcing shared decisions with regard to adoption of innovative ideas, technologies and practices for sustainability

Approach

  • Workshop
    • COSNet +CSS
  • Combine multi-agent and network modelling
    • to investigate the role of the interactionsof characteristics of new practices, and attributes of pastoralists and their networks

    • CSIRO, ANU, Uni Melb
  • Applied
