ABSTRACT

Children and young people are often positioned as the next generation of leaders in whom the public imagines or expects to overcome the legacies of climate and environmental inaction. Increasingly analyses of progress in environmental education independently identify the need for researchers and teachers to ‘listen to children’s voices’. In this paper we argue that climate change education presents a significant platform not only for youth voices, but also for a genuine activation of children’s political agency in schools, universities, and the public domain. In so doing, we draw upon the government funded project Climate Change?+?Me, which has involved working with 135 children and young people from across Northern NSW, Australia as co-researchers investigating young people’s voices in climate change. We conclude that climate change education can open up an entirely new field of educational experience and inquiry when it is inclusive of and led by young people.  相似文献

ABSTRACT

Contemporary social science research on the creative industries demonstrates inequities in accessing good work in this field. Nonetheless, youth still increasingly are seeking to create careers in these fields. However, economic indicators that register growing employment in the creative industries may not fully register the participation of youth. The Young People Making a Living in the Creative Industries research project sought to document the multiple income streams that youth draw on while attempting to make a living in creative fields, mapping the areas of challenge and success in the entry years to creative work. Respondents in the research project articulated an informed knowingness and resistance to the norms of unpaid work in the creative industries and forwarded gender and race as structural categories that impact the experience of entry-level creative work. Respondents also articulated forming communities of care to respond to these challenges, including collectives, support groups, and other forms of networks, while highlighting the challenge of balancing community-based and economic motivations for creative industries work. The study highlights the role of community youth arts programmes on creative industries career incubation for youth, and the need to hear from youth themselves to better map youth participation in the creative industries.  相似文献

Abstract

This article presents a novel geospatial approach to reconstructing and analyzing environmental change over extensive spatial and temporal scales, even in systems such as rivers and streams that are comparatively difficult to digitize. We used a drawing tablet and stylus to digitize features found on historical Army Corps maps across the spatially extensive landscape of the Lower Wabash River’s riparian zone, in Indiana and Illinois, USA. The methodology allows for an efficient reconstruction of sinuous and irregular environmental features, such as sloughs, and demonstrates the utility of digitizing historical maps to understand the evolution of surface water quantity and location across a landscape. We then compared these historical data to contemporary environmental datasets for the same study area to understand what changes have occurred over a 100?year period. This reveals that the hydroscape of the Lower Wabash River has been significantly altered by past human activity, notably through the reduction of swamps, wetlands, and sandbars, and the increase in drainage ditches and overall stream area. Notably, many of these historical alterations are not captured within current environmental datasets.  相似文献

ABSTRACT

This paper establishes a multi theory framework to help explain factors and conditions promoting a political priority for policy change. The framework’s analytical utility is illustrated through its application to a case study of waste management in Australia. A lack of political momentum to prioritise regulatory interventions has contributed to uncoordinated responses by the Australian federal and state governments resulting in unsustainable approaches to waste management. Lessons are derived from the analysis that provide insights into the potential for establishing political priority for policy change from uncoordinated voluntary schemes to more coordinated regulatory approaches.  相似文献

The notion of path dependence has not yet been well explored as a tool for analysing landscape change. Within geography it is primarily economic geographers who have, up until now, shown a keen interest in this concept which stresses the role of social agency and institutions in understanding the development trajectories of regions. Further, the notion of path dependence usefully captures the idea of contingency in historical sequences. This article presents such a perspective on landscape change analysis, discussing two dominant types of sequences in path‐dependent systems. Self‐reinforcing sequences characterize the formation and long‐term reproduction of a given institutional pattern, while reactive sequences describe chains of temporally ordered and causally connected events. From a landscape point of view, by the former we can describe the fixity of practices, by the latter the particular development of (or changes in) landscapes. Within such a framework of path dependence analysis, examples from south‐eastern Latvia, the historical region of Latgale, are used to account for the institution of partible inheritance and to explain its impact on landscapes. The landscape biographies of two villages are studied in order to understand the particular key breaking points and the (series of) reactions that follow from these events. The challenge of using the tool of path dependence analysis lies in its openness for various interpretations, suggesting the need for supplementary theory.  相似文献

Abstract

The Australian Mesozoic fish fauna is considered to be depauperate in comparison with fish faunas in the Northern Hemisphere. However, due to its geographical location as a potential radiation center in the Southern Hemisphere, Australia’s Mesozoic fish fauna is important for understanding fish radiations. Most of the modern fish groups originated during the Mesozoic, but the first records of a modern fish fauna (freshwater and marine) in Australia does not occur until the lower Paleogene. Here, we review all known fossil fish-bearing localities from the Mesozoic of Australia, to improve the understanding of the record. The apparent low Australian Mesozoic fish diversity is likely due to its understudied status of the constituent fossils rather than to a depauperate record. In addition, we review recent work with the aim of placing the Australian Mesozoic fish fauna in a global context. We review the taxonomy of Australian fossil fishes and conclude that the assignments of many actinopterygians need major revision within a modern phylogenetic context. The vast majority of chondrichthyans are yet to be formally described; to the contrary all of the known lungfish specimens have been described. This study considers the microscopic and fragmented remains of Mesozoic fish already found in Australia, allowing a more complete view of the diversity of the fishes that once inhabited this continent.

From 3200 to 2850 cal BP (1250–900 BCE), the Lapita people of the Bismarck Archipelago (Papua New Guinea) undertook voyages eastward that led to their colonization of the eastern outer Solomon Islands, Vanuatu, New Caledonia, Fiji, Tonga and Samoa. The earliest (Lapita) settlements in Fiji were along the Rove Peninsula in southwest Viti Levu Island. At the time of colonization, sea level was 1.5 m higher than today. The Rove Peninsula was then a smaller island off the coast of larger Viti Levu, with a broad, fringing reef along its windward coasts, which was probably the main attraction for Lapita colonizers. As elsewhere during Lapita times in the western tropical Pacific Islands, settlement choice for the initial colonizers of the Fiji Islands was at one level driven by site access, at another by the presence of broad, fringing coral reefs suitable for marine foraging. The earliest settlement along the Rove Peninsula was at Bourewa, occupied first in 3050 cal BP (1100 BCE), where people lived in houses on stilt platforms built along the axis of a subtidal sand barrier; on one side was a broad coral reef, on the other a partly-enclosed tidal inlet. There is no evidence that the Bourewa settlers practised horticulture or agriculture at this time, their subsistence being predominantly marine foraging. After some 300 years of following this subsistence strategy, the inhabitants of Bourewa responded to sea-level fall and the arrival of cultivars (of taro and yam) by including horticulture. As sea level fell further, a total of 550 mm during the Lapita era, the tidal inlet dried up and marine-food resources diminished to a point where the natural environment of the Rove Peninsula could no longer sustain its Lapita inhabitants. All Lapita sites in the area were abandoned about 2500 cal BP (550 BCE), at the same time as the Lapita culture, marked by the end of dentate-pottery manufacture, came to an end in Fiji.  相似文献

The demographic composition of electoral districts has an important influence on the identities of candidates because they affect the political opportunity structures of ethnic minorities and other marginalized groups. The 2018 municipal election in Toronto, Canada provides a unique opportunity to examine how changes to electoral districts impacted the participation of visible minority candidates. At the end of the initial nomination period, the right-wing populist provincial government of Doug Ford reduced the number of city council wards from 47 to 25, which also affected the boundaries of school board districts. Candidates and aspirants then had the opportunity to re-register in the new constituencies. This change constitutes a natural experiment that allows us to isolate the impact of district structure on the relationship between demographics and candidate ethnicity. Using logistic and Poisson regression modeling, we compare the proportion and number of Visible Minority and White candidates before and after consolidation. Contra expectations, we did not find any effect on minority candidates, but show some evidence that consolidation reduced opportunities for Whites. We trace this unexpected finding to the geographic patterns of ethnic settlement.  相似文献

This paper investigates spatial associations between environmental change and violence in Darfur. Long-term variations in the geographical distribution of water and vegetative resources can foster migration from areas with decreasing levels of resource availability to areas with increasing levels. Rising ethnic diversity and resource competition can, in turn, escalate the risk of violence in areas of high in-migration. This paper employs a multimethod approach to investigate this hypothesis. Qualitative evidence is used to demonstrate the plausibility of the argument for the case of Darfur. The quantitative analysis is based on information retrieved from satellite imagery on long-term vegetation change and the spatial distribution of attacks on villages in the early phase of the civil war (2003–2005). The findings indicate that violence has been more likely and intense in areas that experienced increasing availability of water and vegetative resources during the 20 years prior to the civil war.  相似文献

ABSTRACT

The reality of anthropogenic climate change has been established ‘beyond reasonable doubt’ by leading scientists worldwide. Applying a systematic literature review process, we analysed existing literature from 1993 to 2014 regarding climate change education for children and young people, with the aim of identifying key areas for further research. While a number of studies have indicated that young people’s understandings of climate change are generally limited, erroneous and highly influenced by mass media, other studies suggest that didactic approaches to climate change education have been largely ineffectual in affecting students’ attitudes and behaviour. The review identifies the need for participatory, interdisciplinary, creative, and affect-driven approaches to climate change education, which to date have been largely missing from the literature. In conclusion, we call for the development of new forms of climate change education that directly involve young people in responding to the scientific, social, ethical, and political complexities of climate change.  相似文献
