Environmental economics and the Murray-Darling river system
No full textMuch concern about the negative environmental consequences of agricultural development in Australia, including salinisation, waterlogging and algal blooms, has focused on the problems of the Murray–Darling Basin. The aim of this article is to provide an overview of the environmental problems of the Murray–Darling Basin from an economic perspective, and a selective survey of the relevant economic literature, including theoretical analysis, modelling and contributions to the development of water policy. In attempting to understand the complex problems of the Murray–Darling Basin, an eclectic approach drawing on externality, sustainability and property rights perspectives seems most appropriate.Environmental Economics and Policy, Resource /Energy Economics and Policy,
Markets - Water Markets: Australia’s Murray-Darling Basin and the US Southwest
No full textWorldwide supplies of fresh water are increasingly scarce relative to demand. This problem is likely to be exacerbated with climate change. In this paper, we examine water markets in both Australia’s Murray Darling Basin and the western US and their prospects for addressing water scarcity. The two regions share a number of important similarities including: climate variability that requires investment in reservoirs to make water available in low-rainfall periods; the need for internal and cross-border (state) water management; an historical major allocation of water to irrigators; increasing competition among different uses (agricultural, environmental and recreational in situ uses, urban demand); and the potential for water trading to more smoothly and quickly allocate water across these competing uses. A comparison of the two regions provides important insights about how economic factors can encourage more efficient water allocation, market structure and government regulation.

Interview with Jonathan Darling, author of Systems of Suffering: Dispersal and the Denial of Asylum (2022)
No full textThis conversation between Jonathan Darling and Sarah M. Hughes focuses on Darling’s recently published book Systems of Suffering: Dispersal and the Denial of Asylum (2022). Based on research conducted over the course of six years, Systems of Suffering examines the emergence, development, and implications of the dispersal system in the UK. This market-based system of asylum governance is a process that distributes asylum seekers to predominantly urban areas and, Darling argues, represents a form of “distributed violence that is cumulative and incapacitating, and governs through the exhaustion of its critics and subjects” (p. 3). As the conversation unfolds, Darling talks about the implications of the rapidly shifting legal and policy landscape in the UK for the asylum dispersal and the challenges but, he suggests, political urgency of continuing to research it

Water Markets: Australia's Murray-Darling Basin and the US Southwest
No full textFresh water supplies increasingly are under stress in many parts of the world due to rising populations, higher per capita incomes and corresponding consumption, greater environmental concerns, and the effects of climate change. Water rights and markets are part of the institutional menus for responding to these problems. We examine water markets in both Australia’s MDB and the western US and their prospects for addressing water scarcity. The two regions share a number of important similarities including: climate variability that requires investment in reservoirs to make water available in low-rainfall periods; the need for internal and cross-border (state) water management; an historical major allocation of water to irrigators; increasing competition among different uses (agricultural, environmental and recreational in situ uses, urban demand); and the potential for water trading to more smoothly and quickly allocate water across these competing uses. A comparison of the two regions provides important insights about how economic factors can encourage more efficient water allocation, market structure and government regulation. We show that rights are more clearly defined and trading more common in Australia than appears to be the case in the western U.S. Longer periods of scarcity and hence, higher water values may explain this difference.
Benjamin Russel Hanby - Author of Darling Nelly Gray
No full text“Benjamin Russel Hanby - Author of ‘Darling Nelly Gray’,” was first published in April, 1905 as an article in the “Quarterly,” the publication of the Ohio State Archaeological and Historical Society. Author Charles Burleigh Galbreath was an Ohio educator and librarian who twice served as the State Librarian (1896-1911 and 1915-18) and was the secretary and librarian of the Ohio Archaeological and Historical Society (today known as the Ohio History Connection) from 1920 until his death in 1934. Burleigh published numerous articles, pamphlets, and books on Ohio history. This book contains correspondence not published in any other account of Benjamin Hanby’s life.https://digitalcommons.otterbein.edu/archives_hanby/1004/thumbnail.jp
Identifying OH Imposters in the ALFALFA Neutral Hydrogen Survey
No full textOH megamasers (OHMs) are rare, luminous molecular masers that are typically observed in (ultra) luminous infrared galaxies ([U]LIRGs) and serve as markers of major galaxy mergers. In blind emission line surveys such as the Arecibo Legacy Fast Arecibo L-Band Feed Array (ALFALFA) survey for neutral hydrogen (HI) in the local universe, OHMs at z~0.2 can mimic z~0.05 HI lines. We present the results of optical spectroscopy of ambiguous HI detections in the ALFALFA 40% data release (Haynes et. al 2011) detected by WISE but with uncertain optical counterparts. The optical redshifts, obtained from observations at the Apache Point Observatory 3.5m telescope, identified 127 HI optical counterparts and discovered five new OHMs. Fifty-six candidates remain ambiguous. The new OHMs are the first detected in a blind spectral line survey.
The number of OHMs in ALFALFA matches predictions based on the OH luminosity function (Darling & Giovanelli 2002). Additionally, the OHMs found in a blind survey do not seem to differ from those found in previous targeted surveys. This provides validation of the methods used in previous IR-selected OHM surveys and indicates there is no previously unknown OHM-producing population at z~0.2. We also provide a method for future surveys to separate OH and HI lines without expensive spectral observations. This method utilizes infrared colors and magnitudes, such as WISE (Wide Field Infrared Survey Explorer) mid-IR data. Since the fraction of OHMs found in flux-limited HI surveys is expected to increase with the redshift of the survey (Briggs 1998), this analysis can be applied to future flux-limited high-redshift hydrogen surveys
