Developments in flood maps for flood risk management in Scotland

ABSTRACT

Sustainable flood risk management in Scotland is underpinned by the Flood Risk Management (Scotland) Act 2009. Effective delivery of actions to reduce the adverse impact of flooding are dependent on a collaborative approach by Responsible Authorities and a common understanding of flood hazard and risk. Over the last few decades, flood hazard maps have established a prominent role as essential tools in supporting effective flood risk management. They have developed as a result of improved national datasets and advances in computer processing. Improvements in modelling confidence and in the spatial representation of hazard and risk-inform confident actions set out in Flood Risk Management Strategies that coordinate actions supporting adaptation to future hazard conditions. The continued development of the accurate spatial representation of flood hazard and risk is an essential component of enhancing resilience in the face of future climate change.     

The Changing Face of Neolithic and Bronze Age Ireland: A Big Data Approach to the Settlement and Burial Records

This paper synthesizes and discusses the spatial and temporal patterns of archaeological sites in Ireland, spanning the Neolithic period and the Bronze Age transition (4300–1900 cal BC), in order to explore the timing and implications of the main changes that occurred in the archaeological record of that period. Large amounts of new data are sourced from unpublished developer-led excavations and combined with national archives, published excavations and online databases. Bayesian radiocarbon models and context- and sample-sensitive summed radiocarbon probabilities are used to examine the dataset. The study captures the scale and timing of the initial expansion of Early Neolithic settlement and the ensuing attenuation of all such activity—an apparent boom-and-bust cycle. The Late Neolithic and Chalcolithic periods are characterised by a resurgence and diversification of activity. Contextualisation and spatial analysis of radiocarbon data reveals finer-scale patterning than is usually possible with summed-probability approaches: the boom-and-bust models of prehistoric populations may, in fact, be a misinterpretation of more subtle demographic changes occurring at the same time as cultural change and attendant differences in the archaeological record.

The Pied Piper of the ghetto: Lyndon Johnson, environmental justice, and the politics of rat control

When Congress rejected President Lyndon Johnson’s Rat Extermination and Control Bill in the summer of 1967, in a mood of growing conservatism, it inadvertently sparked a heated political controversy that brought the desperate conditions of life in inner-city America into sharp focus. This article focuses on the issue of rat infestation to explore the conditions of “urban blight” that disproportionately afflicted ghetto communities in the United States during the 1960s and that represented a form of environmental inequality linked to racial marginalization and poverty. It is suggested that a growing awareness of environmental aspects of inequality increasingly fueled ghetto discontent, feeding the outbreak of riots during the “long, hot summers,” and spurring liberals to think of new ways to understand the problems of inner-city poverty.
