干旱区生态环境知识资源中心

Social actors in arid regions must develop strategies to respond to available resources which are scarce variable patchy and unpredictable relative to other regions We explore our observations of relationships amongst people and organisations in Australian deserts using a stylised network model of the structure of social networks in arid systems Results suggest that temporal resource variability drives increased network density but with fewer strong ties sparse populations drive a relatively higher proportion of strong ties and that networks develop a hub configuration as resource endowments become more patchy spatially These ideas highlight some issues that warrant improved understanding by actors seeking to enhance livelihoods and local resilience in these extreme environments Crown Copyright (C) 2010 Published by Elsevier Ltd All rights reserved
