Institutional and policy analysis of river basin management: the Murray Darling River Basin, Austrialia
Full text linkThe authors describe and analyze management in the Murray-Darling basin of Australia, long regarded as a model for integrated river basin management. This interior basin of over 1 million km2 in semi-arid southeastern Australia is defined by the catchment areas of the Murray and Darling Rivers and their tributaries. Water management issues include allocation, quality, and dryland salinity. Because of Australia's federal governmental structure, institutional development has been more a matter of integrating state and local endeavors than decentralization of national authority. The Australian national government has little constitutional power over water resources. The five states in the basin make policy regarding water rights, discharge permits, fees, and the construction and operation of physical structures. River management began on the Murray River in the 1920s under the terms of a tri-state agreement. As the scope of management widened to the entire basin, more states were added and the national government supported the creation of new arrangements for integrated water resource management, with some provision for stakeholder participation. The dynamics of state-national authority over water policy, and the emergence in recent years of numerous local-level catchment organization, contribute to some uncertainty about the future course of basin management in this internationally renowned site.Water and Industry,Water Conservation,Water Resources Law,Environmental Economics&Policies,Water Supply and Systems,Town Water Supply and Sanitation,Drought Management,Water and Industry,Water Conservation,Water Supply and Sanitation Governance and Institutions
Jeremiah in Tara:British Israel and the Irish past
No full textMedieval and early modern historiography had encouraged the integration of biblical and Gaelic chronologies, and throughout the eighteenth and nineteenth centuries Irish antiquarians, poets and romantic nationalists began to think of themselves as ‘Milesians’, the displaced descendants of a wandering Phoenician tribe. This chapter focuses on the British Israelites, a loose Protestant sect united by their belief that the Anglo-Saxon race was descended from the Lost Tribes of Israel and that biblical prophecies on the future of ‘Israel’ referred to the British Empire. The British Israelites argued that the ancient Irish king, Ollamh Fodhla, was actually the Hebrew prophet Jeremiah. This myth-history was deployed in support of the British-Israel claim that the Anglo-Saxons were the true heirs to the biblical Kingdom of David. Yet despite their fascination with the mysteries of pre-Christian Ireland, most British Israelites were arch-imperialists, staunch anti-Catholics and opponents of Irish Home Rule. The chapter explores shifting notions of British and Irish racial identity in relation to scriptural genealogy, and argues that Old Testament narratives were co-opted to serve conflicting political and religious agendas
Markets - Water Markets: Australia’s Murray-Darling Basin and the US Southwest
Full text linkWorldwide 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.

Abstract
Land management practices such as irrigation, crop rotation and crop type affect soil properties. The objective of this study is to determine the effect of common land management practices in western Kentucky including non-irrigated, irrigated, and pasture ground on selected soil properties. Undisturbed and disturbed soil samples were collected from two fields in each of the three locations, from the depth of 1-3 inches and 3-6 inches. The fields in Princeton, KY were double crop soybeans in a no-till operation. In Simpson County, the fields were planted in corn, on a no-till operation and the field in Ohio County, KY was a non-irrigated pasture for grazing purposes. Soil samples in Princeton, KY were taken on September 8th and in Simpson County, KY, samples were collected on September 16th, 2017 due to flooding issues. In addition, soil samples in Ohio County, KY were taken on September 9th, 2017. All samples were analyzed for soil water holding capacity, soil water at field capacity, soil organic matter, bulk density, porosity and soil acidity level. Data from this study will be described in detail on the poster. The results will show if irrigation practices can improve soil conditions in a corn-soybean crop rotation.

Water Markets: Australia's Murray-Darling Basin and the US Southwest
Full text linkFresh 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.
Coherent two photon excitation within an extended cloud of Rubidium 85 for the purposes of atomic interferometry and cooling
No full textCold atom samples, at temperatures of the order 100 µK, are useful for a wide reaching array of new and exciting technological and scientific endeavours. Atoms are conventionally cooled by Doppler cooling, which relies on the continuous absorption and re-emission of photons in a closed optical cycle. This requirement is difficult to achieve when there are many allowed decay paths for the excited atom, making Doppler cooling only feasible for a handful atoms with simple energy level structures. More exotic energy level structures, such as those found in molecules, are notoriously difficult to cool. Coherent cooling schemes in comparison, offer advantages such as insensitivity to frequency detuning or a higher number of photon momenta which can be imparted for each spontaneous emission event making them promising candidates for the optical cooling of particles with more general energy level structures. In order to demonstrate these schemes, we have explored the coherent manipulation of an atomic cloud of Rubidium cooled using a two photon Raman resonance. Despite the long spontaneous decay times of such systems, we find a significant decay in the fidelity of the coherent manipulations, which we have characterised using the techniques of Raman spectroscopy, Rabi oscillations, Ramsey interferometry and spin echo. We have found the minimum time constant for the decay in the decoherence to be 2.1fi0:2 ms, which is a result of non-radiative and partially non-stochastic dephasing mechanisms. Due to a high level of decoherence during the spin-echo experiments further investigation is required to determine the exact ratio of stochastic to non-stochastic dephasing
