Our model can be used for understanding the conditions of sustainability for indigenous communities relying on subsistence agriculture and hunting, and for scenario analyses to examine the implications of external interventions.
Using this model, we then demonstrate how a number of external interventions in the structure and/or organization of market interactions (occurring before trade, after trade, or during negotiations themselves) can profoundly alter the nature of these dispositions.
The number of external interventions, whilst necessary, do not unfailingly support pastoral interests or respond to pastoral concerns.
Both perspectives implicitly contain a critique of external interventions by predominant actors and powerful stakeholders as well as a repudiation of capitalist and communist concepts of modernization.
The challenge this poses is how to elicit correct information from the community members, while at the same time avoid raising their expectation of external interventions, as this may affect their design of community actions.
Furthermore, visualization of the causal relationships among variables on a graph could help understand and interpret complex biological systems, while their quantification allows prediction of outcomes of external interventions applied to such a causal network.
