We identify and offer new explanations of change in water management infrastructure in the semi-arid urban hinterland of Anuradhapura, Sri Lanka between ca. 400 BC and AD 1800. Field stratigraphies and micromorphological analyses demonstrate that a complex water storage infrastructure was superimposed over time on intermittently occupied and cultivated naturally wetter areas, with some attempts in drier locations. Our chronological framework, based on optically stimulated luminescence (OSL) measurement, indicates that this infrastructure commenced sometime between 400 and 200 BC, continued after Anuradhapura reached its maximum extent, and largely went into disuse between AD 1100 and 1200. While the water management infrastructure was eventually abandoned, it was succeeded by small-scale subsistence cultivation as the primary activity on the landscape. Our findings have broader resonance with current debates on the timing of introduced ‘cultural packages’ together with their social and environmental impacts, production and symbolism in construction activities, persistent stresses and high magnitude disturbances in ‘collapse’, and the notion of post ‘collapse’ landscapes associated with the management of uncertain but essential resources in semi-arid environments.  相似文献

What can professional land managers gain by consulting with local communities? Scientific knowledge provides valuable insights into the causes of environmental change and the processes by which it occurs but often lacks a historical dimension. Recollections of local people can supplement both historical records and scientific understandings of cause and process to achieve a more comprehensive picture of change over time. However, the process of memory is tied to life experience and is highly selective. Any attempt to use oral accounts in constructing a picture of environmental change over time must also include an analysis of the process of memory itself. Drawing on oral histories with long term residents of the Tumut region of NSW, this paper explores the nature of local environmental knowledge and evaluates oral history as a source of information for understanding environmental history and the impact of changing patterns of land use.  相似文献

In this paper, we use the funeral space and its liminal nature as a milieu for exploring how a ‘modern’ health intervention, the mosquito bednet, is negotiated by its recipients in relation to its (non)-usage in such spaces. With a focus on sleeping arrangements at funerals and drawing on empirical data from participants living in rural southern Tanzania, we discuss how the bednet is linked to the notion of being unsympathetic to the death. Viewed as a symbol of modernity and a reflection of wealth and individual pride, the bednet becomes physically and symbolically inappropriate in the more sacred, ‘in-between’ site of the funeral. We also uncover how risk perceptions regarding malaria transmission are re-cast in funeral spaces, with socio-cultural practices and health-related behaviours being simultaneously ‘risky’ for individual mourners and reinforcing in terms of group social cohesion. As individual mourners' concerns about malaria risks are suspended, notions of pain and discomfort come to the fore as part of the mourning process and respect for the deceased.  相似文献

The author focuses her approach on the quite unknown actor’s figure, central in the theatrical activity of the jesuit colleges, at the end of the sixteenth and beginning of the seventeenth century. The author attempts to decipher the portrait of the christian actor, an antiactor invested by all the strenght of truth whose image is feigned by the comedian. But, more generally, the paper places the actor of Jesuit religious dramas, which were often written by the professors of the colleges, in the framework of those colleges, which constitutes the ultimate guarantee, since the actor is a student, and in no way a future actor, of the specificity of this theatre.  相似文献

The United Nations World Social Report (2020) reveals that more than two thirds of the world's population live in countries where urban inequalities have increased in the last three decades. While urban inequalities are traditionally characterized as an economic issue, scholars are increasingly applying methods from geospatial analysis to study them. In the context of these advancements, it remains unclear what underlying perspectives are guiding decisions to concentrate on certain aspects of urban inequalities, while potentially ignoring others. We address this gap by reviewing the literature centered on the geospatial analysis of urban inequalities and identify three predominant research lenses from accessibility, distribution, and policy and stakeholder perspectives. As a primary contribution of this article, we connect the perspectives with ideas drawn from complexity theory to develop an overarching socio-technical framework for how urban inequalities emerge over space and time. While traditional scientific frameworks seek to increase knowledge through causality, complexity science acknowledges the inherent challenges in defining, understanding and solving complex problems such as urban inequalities, which has profound implications for their representation, modeling and interpretation. We critically reflect on the framework through key relational themes and insights drawn from the literature and close with considerations for future research.  相似文献
