Understanding Social Complexity Within the Wildland–Urban Interface: A New Species of Human Habitation?

The lack of knowledge regarding social diversity in the Wildland Urban Interface (WUI) or an in-depth understanding of the ways people living there interact to address common problems is concerning, perhaps even dangerous, given that community action is necessary for successful wildland fire preparedness and natural resource management activities. In this article, we lay out the knowledge and preliminary case study evidence needed to begin systematically documenting the differing levels and types of adaptive capacity WUI communities have for addressing collective problems such as wildland fire hazard. In order to achieve this end, we draw from two theoretical perspectives encompassing humans' interactions with their environment, including (1) Kenneth Wilkinson's interactional approach to community, (2) and certain elements of place literature. We also present case study research on wildfire protection planning in two drastically different California communities to illustrate how social diversity influences adaptive capacity to deal with hazards such as wildland fire. These perspectives promote an image of the WUI not as a monolithic entity but a complex mosaic of communities with different needs and existing capacities for wildland fire and natural resource management.     

Wildland–Urban Interface Fires and Socioeconomic Conditions: A Case Study of a Northwestern Patagonia City

In many regions of the world, fires are primarily of anthropogenic origin. In northwestern Patagonia, the number of fires is not correlated with meteorological variables, but is concentrated in urban areas. This study was conducted in the wildland–urban interface (WUI) area of San Carlos de Bariloche (Patagonia, Argentina), within the Nahuel Huapi National Park. WUI fires are particularly problematic because, besides people and goods, they represent a danger to protected areas. We studied the relationship between fire records and socioeconomic indicators within the WUI of San Carlos de Bariloche. We conducted a Multiple Correspondence Factorial Analysis and an Ascendant Hierarchical Classification of the city neighborhoods. The results show that the neighborhoods in Bariloche can be divided into three classes: High Socioeconomic Fire Risk neighborhoods, including neighborhoods with the highest fire rates, where people have low instruction level, high levels of unsatisfied basic needs and high unemployment levels; Low Socioeconomic Fire Risk neighborhoods, that groups neighborhoods which present the opposite characterization, and Moderate Socioeconomic Fire Risk neighborhoods, which are more heterogeneous. Once neighborhoods were classified, a Socioeconomic Fire Risk map was generated, supplementing the existing WUI Fire Danger map. Our results emphasize the relevance of socioeconomic variables to fire policies.     

Creating Defensible Space in the Wildland–Urban Interface: The Influence of Values on Perceptions and Behavior

We examined the effect that value orientation to forests and wildland fire management has on an individual’s decision to create defensible space around his or her residence in the wildland–urban interface. Using data from a mail-back questionnaire, respondents in north central Minnesota were clustered by basic value–laden beliefs toward forest and wildland fire management and compared across a number of perceptions and behaviors related to creating defensible space around residences. Value orientation groups differed in attitudes, subjective norms, and perceived behavior control toward creating defensible space. In addition, relative effects of these perceptions on intention to create defensible space differed across groups. Implications lie in (a) understanding differences in motivations and reasons for support of strategies for managing fires near the wildland–urban interface, (b) developing information designed to address the perspectives of different groups related to creating defensible space, and (c) contributing to an improved integration of land management and public concerns and interests.     

Exploring the ‘Issue-Attention Cycle’: Does Length of Time Since Wildfire Predict Social Acceptability of Prescribed Burning?

Environmental Management - Social acceptability of environmental management actions, such as prescribed burning used to reduce wildfire risk, is critical to achieving positive outcomes. However,...     

Does mode matter? A comparison of telephone,mail, and in-person treatments in contingent valuation surveys

The choice of survey mode in contingent valuation research has long been debated in the literature. However, there is limited evidence as to how mode impacts behavior. Using an identical survey administered with telephone, mail, and in-person interviews, this is the first research to examine mode effects using all three commonly employed modes in contingent valuation research. Results show that there is some evidence of social desirability bias in the telephone survey. In addition, the role of income in the decision-making process is an important consideration.     

“The Lucky country”? A critical exploration of community gardens and city–community relations in Australian cities

Urban agriculture (UA) has the potential to expand beyond the grassroots level to meet the social, cultural, economic and food needs of urban dwellers. At its core, UA represents an alternative use of urban space that occurs with or without government support or approval. The experiences of community gardeners and their views of, and engagement in, community gardens as a form of UA, or local “alternative food networks”, is a focal point of this paper. Relying on Australian city case studies, this paper explores community gardens, using critical urban approaches concerning “rights to the city” and diverse economies. Findings from this study reveal how community gardeners understand and participate in diverse economies and extended local food networks. They also identify respondents’ views of local councils as barriers to the emergence of community gardens, and other forms of UA, as a local response to growing concerns over impacts of the global food chain on food security. In contrast to other Western cities, effective city–community relations for community garden growth have yet to emerge in Australian cities, as key policy areas for urban sustainability and social cohesion.     

How can public–private partnerships contribute to security and human rights policy and practice in the extractive industries? A case study of The Democratic Republic of Congo (DRC)

Across sub-Saharan Africa, the presence of foreign large-scale mining companies is increasing. This is in part a result of depleting resources in countries such as Canada, United States and Australia, and in part from a more favorable national mine investment climate in several mineral-rich African countries. Their increased presence raises important questions around the potential role and function of Corporate Social Responsibility (CSR) in the sector. In post-conflict and/or fragile states, CSR has further implications for conflict and risk mitigation strategies to ensure the protection of human rights. One CSR approach increasingly being considered is the public–private partnership, whereby companies, public donors, and development agencies leverage their relationships for mutual benefit. There is merit in exploring its function in post-conflict fragile states, where socio-economic needs are high and the capacity of the state to respond to a variety of mine governance challenges is limited. Two case studies from the Democratic Republic of Congo (DRC) are presented, and their policy implications, discussed.     

Does Human-Induced Habitat Modification Influence the Impact of Introduced Species? A Case Study on Cavity-Nesting by the Introduced Common Myna (Acridotheres tristis) and Two Australian Native Parrots

Introduced species pose a major threat to biodiversity across the globe. Understanding the impact of introduced species is critical for effective management. Many species around the world are reliant on tree cavities, and competition for these resources can be intense: threatening the survival of native species. Through the establishment of 225 nest boxes, we examined the relationship between tree density and the abundance and nesting success of three bird species in Canberra, Australia. The common myna (Acridotheres tristis) is an introduced species in Australia, and the crimson rosella (Platycercus elegans) and eastern rosella (Platycercus eximius) are native species. We then investigated the impact of common myna nest box occupation on crimson rosella and eastern rosella abundance. Tree density significantly influenced the abundance and cavity-nesting of all three species. Common myna abundance (birds per square kilometer) was greatest at low tree density sites (101.9 ± 22.4) and declined at medium (45.4 ± 10.1) and high (9.7 ± 3.6) tree density sites. The opposite pattern was observed for the crimson rosella, with greater abundance (birds per square kilometer) at high tree density sites (83.9 ± 9.3), declining over medium (61.6 ± 6.4) and low (31.4 ± 3.9) tree density sites. The eastern rosella was more abundant at medium tree density sites (48.6 ± 8.0 birds per square kilometer). Despite the strong influence of tree density, we found a significant negative relationship between common myna nest box occupancy and the abundance of the crimson rosella (F _1,13 = 7.548, P = 0.017) and eastern rosella (F _1,13 = 9.672, P < 0.001) at some sites. We also observed a slight increase in rosella nesting interruptions by the common myna at lower tree densities (high: 1.3 % ± 1.3, medium: 6.6 % ± 2.2, low: 12.7 % ± 6.2), although this increase was not statistically significant (F _2,40 = 2.435, P = 0.100). Our study provides the strongest evidence to date for the negative impact of the common myna on native bird abundance through cavity-nesting competition. However, due to the strong influence of habitat on species abundance and nesting, it is essential to investigate the impacts of introduced species in conjunction with habitat variation. We also suggest one component of introduced species management could include habitat restoration to reduce habitat suitability for introduced species.
