Highlighting the Need and Potential for Use of Interdisciplinary Science in Adaptive Environmental Management: The Case of Endangered Upland Swamps in the Blue Mountains,NSW, Australia

The Blue Mountains region of New South Wales, including the World Heritage listed Blue Mountains National Park, is arguably one of Australia's most highly valued and iconic wilderness areas. Common to this region are upland swamps (formally ‘temperate highland peat swamps on sandstone’), which play a vital hydrological role at the headwaters of the river catchments, as well as providing the habitat for an array of flora and fauna species. This paper involves an interdisciplinary examination into the need and potential for adaptive management in the Blue Mountains. It uses geomorphic (physical) knowledge of swamp condition and social data about the volunteers who rehabilitate them. Research involved using the River Styles river condition framework across 47 swamps and questionnaires and interviews with local rehabilitation volunteers. It is proposed that there is a need and a potential to combine geomorphic understanding with further engagement of community volunteers in order to enable an interdisciplinary approach to adaptive management. Such an approach could result in the effective environmental management of upland swamps in the Blue Mountains.     

Gendered Nations: Nostalgia,development and territory in Ecuador {1}

Drawing upon original substantive research, the paper argues for a consideration and analysis of the imagined geographies of gendered nations. Drawing upon Anne McClintock's work on temporality, the article proposes that a gendered spatiality underlies discourses of nationhood. Focusing particularly on national press and government reports over recent years in Ecuador, it is suggested that women appear in the national discourses around nostalgia, development and territory. While previous work has frequently noted the ambivalent position of women in the modern project of nationhood, the way in which this ambivalence is structured around place (and also significantly around 'race' and class) has not received as much attention. Geographers and feminists have not been as attuned as they might to the complex gendered imaginative geographies of the nation, and the multiple ways in which the nation constitutes gendered subjectivities.     

Social capital, environmental health and collective action: a Hamilton, Ontario case study

This article explores the relationships among environmental health, social capital and collective action in the industrial city of Hamilton, Ontario, Canada. Survey results from 512 households are used to document intra-urban variation in levels of social capital (defined as norms, networks and trust) and collective action in the context of environmental health issues, and specifically air quality. Despite real differences between areas in terms of socio-demographic characteristics, little variation in either social capital or collective action by area was observed. Further, while social networks and community involvement were significant predictors of collective action, indicators of norms and trust were not. Hence, the conception of social capital as a unitary construct that produces place-specific benefits is not reflected in the example explored here.     

Local Knowledge and Economic Realities Affecting Soil Erosion in the Rach Rat Catchment,Vietnam

Several parts of Binh Phuóc Province, southern Vietnam, suffer from degraded soils and vegetation as a result of both natural erosion of weak mud rocks and sandstones and intensive human activity, especially through land clearing for agriculture on unstable slopes, deforestation, and abandonment of poor farmland. The underlying cause of this land degradation has been the farming habits of migrants of varying ethnic groups who have settled in the area since 1980. The indigenous farming knowledge of these people and the role of that knowledge in soil erosion were examined by a series of household surveys. They enabled farming practices to be related to ground cover established from a 2002 Landsat 7 ETM (Enhanced Thematic Mapper), and erosion data from a series of erosion bridge measurements. A GIS (Geographical Information System) approach was piloted as a means of identifying areas vulnerable to erosion. This could then be combined with the understanding of farming practices to reveal the relative roles of farmer behaviour, crop cover, and slope and soil characteristics in the erosion process. Land use, local people's knowledge and economic realities are the main factors, as well as natural conditions, that drive this land degradation.     

Matching Geospatial Concepts with Geographic Educational Needs

In this paper, we assume that learning to comprehend the geospatial environment would be significantly facilitated by developing a multi‐level task ontology that identifies various levels and complexities of geospatial concepts. We suggest that, apart from four spatial ‘primitives’– identity, location, magnitude, and space‐time – all geospatial concepts involve ‘inheritance’ characteristics. The more complex and abstract the concept, the larger the inheritance links that need to be appreciated to enhance concept understanding. For example, many basic geospatial concepts – such as direction and distance – are first‐order derivatives from the ‘location’ primitive, whereas concepts such as spatial association, map projection or interpolation are high‐order concepts that require several layers of geospatial concepts in their derivation. Having offered a five‐level ontology for concept organisation, we suggest sets of tasks that could establish an understanding of concepts, thus directly making the environment more legible in a spatial sense. We develop this framework in the context of the teaching of geography in grades from kindergarten to the final years of high school (grade 12 in the United States system). Our conceptualisation is grounded in the US school system – in which geography is usually absent in the curriculum.
