A geography of residents' worry about the disruptive effects of contaminated sites

While the links between contaminated sites and adverse effects on human health and well‐being are being increasingly recognised, some argue that the magnitude of the health problem is inadequately addressed because it is largely invisible. Health geographies literature has sought to highlight this invisibility by focusing on the link between contaminated sites and health. This study adds to health geographies by presenting unique insights into the geography of residents' worry about the disruptive effect of environmental contamination on health and well‐being. It analyses a sample of residents (n = 485) living near 13 contaminated sites across Australia. Ordinal logistic regression analysis of closed‐format survey questions was combined with coding of open‐ended survey questions to reveal the geography of residents' worry about contamination from nearby sites. First, the study explores some of the main relationships between residents, their environs, and contaminants from nearby source sites, which determines their levels of worry: residents' demographics, residents' proximity to sites, contaminant boundaries and borders, and type of contaminant. Second, the study investigates how worry affects residents' health and well‐being, ranging from effects on their personal functioning through to their sense of ontological security, which depends in part upon their perceptions of contaminants' impacts. Despite having identified a range of diverse and negative effects of worry about contamination on residents, we found that worry for contamination can also prompt coping strategies and problem‐solving, reinforcing the need for more research on this subject.     

The Unofficial Commonwealth Relations Conferences, 1933–59: Precursors of the Tri-sector Commonwealth

One of the unique features of the Commonwealth as an international association is the width and depth of its non-political manifestations. At recent Commonwealth conferences political and official consultations have been held in parallel with large civil society, business and youth forums and, in some cases, inter-faith dialogues. Growing collaboration between the political, civil society and business elements gives rise to the notion of the ‘tri-sector Commonwealth’. The concept of an ‘association of peoples’ as well as one of nations, does, however, have a long pedigree. Between 1933 and 1959 a series of Unofficial Commonwealth Relations Conferences, organised by Chatham House and its overseas affiliates, were held at roughly five-yearly intervals to analyse the implications of the most recent Imperial Conferences. Politicians and civil servants joined with lawyers, academics, editors, military men, agriculturalists and trade unionists. In contrast to the political Commonwealth, women had a part in the unofficial conferences. And among more than 400 participants at Toronto 1933, Lapstone 1938, London 1945, Bigwin 1949, Lahore 1954 and Palmerston North 1959 were fifty-five academic historians and other writers of history, who included most of the leading authorities on the Commonwealth of the 1930s and 1940s.     

Palestinian Water: Resources,Use, Conservation,Climate Change,and Land Use

This article addresses the future of freshwater resources in the Palestinian West Bank through a discussion of contemporary issues that each plays a vital role in determining the long‐term sustainability of freshwater reserves, such as water resource availability, trans‐boundary water issues, water reuse and conservation, changes in land use, and the potential impact of climate change on long‐term water management. Climate change and changing land use patterns are already altering this region's water resources. Future predictions regarding the long‐term effects of these changes are complex and therefore inherently uncertain. However, the consensus among most studies on this subject indicates that currently water‐poor regions such as the Middle East will experience even greater water stress in the future. Nearly all of the freshwater consumed in the West Bank is obtained from local groundwater supplies that are suffering overdraft as well as decreasing water quality. Climate change will exacerbate water stress by increasing overall temperatures, decreasing and fluctuating precipitation, and reducing overall aquifer replenishment. Expanding urbanization will continue to strain freshwater supplies by negatively impacting the quality and quantity of available freshwater. Water management in the West Bank is further complicated by total Israeli control over water resources, which often causes water delivery to Palestinians in this region to be marginalized. This article finds that Palestinian and Israeli water managers must plan for future water crises, which will likely be a result of the combined effects of increasing urbanization and climate change coupled with exponential population growth.     

Iron precipitation in a natural CO2 reservoir: Jurassic Navajo Sandstone in the northern San Rafael Swell,UT, USA

Diagenetic iron (oxyhydr)oxide minerals are common precipitates expected in CO₂ reservoirs, and these minerals record fluid flow for application to carbon capture and sequestration (CSS). Multiple mineralogy and spectroscopy analyses on a pore to meter scale characterize a well‐exposed, lithologically controlled, iron (oxyhydr)oxides reaction front in the Jurassic Navajo Sandstone. Dolomite is the most prevalent cement (up to 23 area%), followed by only several percent or less of iron (oxyhydr)oxides, kaolinite, illite, and gypsum cements. Bulk geochemistry based on diagenetic mineralogies in the reaction front is compared with the water chemistry from nearby modern spring effluent emanating from the Navajo Sandstone to conclude that similar fluids (i.e., CO₂‐charged, saline waters containing hydrocarbons) are responsible for the precipitation. A second comparison of bulk geochemistry and diagenetic mineralogies of the reaction front with data from other abundant Navajo Sandstone concretions in the Spencer Flat region (in south central Utah) shows that reservoir fluids likely vary spatially and temporally in the porous and permeable Navajo Sandstone. CO₂ injection into porous and permeable, quartz arenite, saline aquifers will likely result in minor clay and abundant dolomite precipitation that will significantly decrease porosity.
