Resilience and Regime Shifts: Assessing Cascading Effects

Most accounts of thresholds between alternate regimes involve a single, dominant shift defined by one, often slowly changing variable in an ecosystem. This paper expands the focus to include similar dynamics in social and economic systems, in which multiple variables may act together in ways that produce interacting regime shifts in social-ecological systems. We use four different regions in the world, each of which contains multiple thresholds, to develop a proposed general model of threshold interactions in social-ecological systems. The model identifies patch-scale ecological thresholds, farm- or landscape-scale economic thresholds, and regional-scale sociocultural thresholds. Cascading thresholds, i.e., the tendency of the crossing of one threshold to induce the crossing of other thresholds, often lead to very resilient, although often less desirable, alternative states.

Resilience, adaptive capacity, and the lock-in trap of the Western Australian agricultural region

Using the Western Australian (WA) agricultural region as an example of a large-scale social-ecological system (SES), this paper applies a framework based on resilience theory to examine the regions resilience and capacity for change and renewal. Despite numerous policies directed at controlling natural resource degradation in this SES, sustainable natural resource management (NRM) has not been achieved. Disparities between the scale and complexity of the problem, the design of management policies, and regions history have all contributed to policy resistance. Historically, when considered as an integrated system, changes may be described by two iterations of the adaptive cycle. These cycles are also synchronous with the third and fourth Kondratiev long-wave economic cycles. The WA agricultural region has experienced sequential periods of growth and accumulation followed by reorganization and renewal, and currently is in the backloop (reorganization to exploitation phases) of the adaptive cycle. A regions adaptive capacity is achieved by substituting direct reliance on regional factors with institutional intervention and sophisticated technology, often generated at the global scale. This substitution alters the thresholds of the commodity system and gives the perception of an adaptive system. In contrast, however, if resource depletion, environmental pollution, and population decline, also effects of the commodity system, are included within the model then the region may be considered to be in a Lock-in pathological trap. We propose that the dynamics of land-use change between 1900-2003 were driven by macroeconomics at the global scale, mediated by institutions at the national and state scale. Also, the SES, which is composed of relatively fast-moving variables, is largely decoupled from the slow-moving ecological variables.

Natural resource management at four social scales: psychological type matters

Understanding organisation at different social scales is crucial to learning how social processes play a role in sustainable natural resource management. Research has neglected the potential role that individual personality plays in decision making in natural resource management. In the past two decades natural resource management across rural Australia has increasingly come under the direct influence of voluntary participatory groups, such as Catchment Management Authorities. The greater complexity of relationships among all stakeholders is a serious management challenge when attempting to align their differing aspirations and values at four social institutional scales—local, regional, state and national. This is an exploratory study on the psychological composition of groups of stakeholders at the four social scales in natural resource management in Australia. This article uses the theory of temperaments and the Myers-Briggs Type Indicator (MBTI®) to investigate the distribution of personality types. The distribution of personality types in decision-making roles in natural resource management was markedly different from the Australian Archive sample. Trends in personality were found across social scales with Stabilizer temperament more common at the local scale and Theorist temperament more common at the national scale. Greater similarity was found at the state and national scales. Two temperaments comprised between 76 and 90% of participants at the local and regional scales, the common temperament type was Stabilizer. The dissimilarity was Improviser (40%) at the local scale and Theorist (29%) at the regional scale. Implications for increasing participation and bridging the gap between community and government are discussed.

Understanding and Conceptualizing Risk in Large-Scale Social-Ecological Systems

Many of the most serious global impacts have emerged from the interaction of human activities in the scientific-technical-industrial system. Changing from largely disciplinary science to multi- and ultimately interdisciplinary science and management requires a new ontology and epistemology to be negotiated to help us understand complexity within the social context and how this relates to risk. This paradigmatic shift currently taking place in science is contributing to the development of new theory and practice. Systems thinking is often considered key to solving ill-defined complex environmental and social problems displaying uncertainty and increased risk. But it is unclear what this thinking is or would be and how it might be progressed in future. For the necessary change to occur I suggest an important step is to integrate the diversity of knowledge through developing a framework to share information across multiple ontologies and epistemologies to gain acceptance across the sciences.
