…theory modelling results I: Smallness drives individuals to have stronger links. Desert systems also tend to lack critical mass; this drives individuals to favor fewer but stronger links II: Uncertainty of resources drives individuals to have weaker, but more numerous links to others III: Where cooperative objectives drive networks, links are stronger but fewer IV: If one individual contains greater resources, than it can form a hub

…generalised implications Need to promote networks that favour a diverse range of weak ties over a more selective range of stronger ties, This needs to be supported by a culture which allows for the effective and efficient activation of the ties in times of need. Many arid Australia networks already have such characteristics. Where they do not, they could be encouraged by actions to reduce the transactions costs associated with networking, and cultural and formal institutions that explicitly foster flexibility and cooperation.
