Decision Making and Uncertainty: Bayesian Analysis of Potential Flood Heights

This paper provides a case study of a method to estimate the value of additional information, before its acquisition, to aid decision making in the face of uncertainty. The approach employs conditional simulation in a Monte Carlo framework to conduct a Bayesian assessment of the value of information in an explicitly spatial setting. This paper demonstrates the procedure as applied by a hypothetical decision maker concerned with coastal flood control where flood damage is dependent on the spatial distribution of elevation. A set of known survey points provides the decision maker with limited knowledge of elevation. The method explored in the paper allows the decision maker to ascertain the potential value of additional survey information in terms of its ability to reduce uncertainty about flood damage.     

Land Classification: Providing an Explanation for the Decision Making Process

This paper considers the impact of technology on methods used to classify land potential. With developments in new technologies such as Expert Systems (ES) and Geographic Information Systems (GIS), McKeown (1987) proposes a new method by which to explain the decision making process for land classification to an end user. Consideration is given to McKeowns' concept and the literature reviewing both traditional land classification methods and ES and GIS systems.     

Assessing Representation at Different Scales of Decision Making: Rethinking Local is Better

The nature and quality of representation in public participation is crucial to reaching acceptable environmental decisions that can be implemented. Ten case studies of natural resource management groups involved in agriculture in south western Australia were conducted at four spatial scales—state, regional, land conservation district (shire or county), and subcatchment. Qualitative analysis identified the desirable qualities of representatives, and then compared perceptions of current practice at the four scales against these ideals. Desirable qualities were being an active participant, competency (skills and knowledge), credibility, adopting the group identity and commitment, communicating outside the group, having established social networks, and an ability to function in multiple roles. Analysis across scales suggests that for groups at broader spatial scales of organizing, such as the state level, representation was closer to achieving the desired qualities than at other scales. This finding is contrary to much of the current rhetoric in natural resource management, and environmental management more generally, that "local is better." The article concludes with some thoughts as to why this is the case, suggesting that the success or otherwise of representation, and the public participation in which representatives are involved, is influenced not only by the scale of decision making but also by how representatives are selected and what they are expected to achieve.     

From Mission to Maynggu Ganai: The Wellington Valley Convict Station and Mission Site

The Wellington Valley Convict Station and Mission site, now known as Maynggu Ganai Historic Site (meaning “people’s land” in local Wiradjuri language), contains the archaeological remains of the convict agricultural station that was established in 1823. The site, subsequently taken over by the Anglican Church Missionary Society as a mission to the Wiradjuri, operated from 1832 to 1844. Drawing upon archaeological survey, the extraordinary historical archive associated with this site, and an analysis of community consultative research, this article explores the role of this site in colonial cultural exchange, as well as the contemporary cultural meanings of this history and its physical remains for the community today.
