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

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

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
