Role of networks on

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 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

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.


Exploring the role of networks on strategic decisions making of pastoralist in central australia

  • 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


Develop a proposal

Develop a proposal

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

  • Collaborative

    • CSIRO, ANU, Uni Melb

  • Applied

    • involving stakeholders – Desert Knowledge CRC
