Horizontal drilling and hydraulic fracture stimulation have enabled the economic development of unconventional resource plays. An average horizontal well in the Barnett Shale requires 3 to 4 million gallons of fresh water, 90% of which is used for hydraulic fracture stimulation. While the water consumption of Barnett Shale operations is less than 1% of total Region C consumption, extended drought conditions and competing demands for water resources are placing pressure on operators to reduce terminal water consumption. Strategies which reduce water requirements associated hydraulic fracture stimulation without compromising the efficiency and cost of energy production are essential in developing a comprehensive policy on energy-water management. Recycling and reuse technologies were evaluated on the basis of performance, cost, and capacity to treat reclaimed flowback water and oilfield brine. Recycling flowback fluids for future hydraulic fracture applications is the most practical repurposing of oilfield waste. The low TDS content of flowback derived from water-based fracs permits multiple treatment options. Mobile thermal distillation technology has emerged as the prevailing technique for recycling flowback water, yielding maximum water savings and reduced operating costs. The estimated cost of recycling flowback water by thermal distillation is $3.35/bbl. Compared to the current cost of disposal, recycling provides an opportunity to minimize waste and reduce the fresh water requirements of hydraulic fracture stimulation at an incremental cost. The stewardship role of the Texas Legislature is to protect the water resources of the state and to facilitate the Regional Water Planning Process, ensuring future water needs are met. The support and participation of the Legislature and other planning entities is critical in advancing the energy-water nexus. As operators pursue innovative water management practices to reduce terminal water consumption in the oilfield, the Barnett Shale positions itself as a model for sustainable water use in the development of unconventional shale resources. The cost of recycling and reuse technology limits the participation of small and mid-size operators who possess the greatest market share of the Barnett Shale. Funding for research and implementation of water-conscious strategies such as shared recycling facilities, CO2 capture and storage, and pipeline infrastructure would create multi-user opportunities to promote conservation and reduce net consumption of fresh water supplies. Through the integration of technology and policy, terminal water consumption in the Barnett Shale can be greatly diminished. / text

The concept of resource nexus is an acknowledgement of the interconnections between the uses of natural resources. This research will further the work done on the resource nexus by examining the multiple effects of measures taken in the Indian textile industry to lower the costs incurred due to the implementation of Zero Liquid Discharge (ZLD). ZLD combines a variety of technologies to cease the discharge of untreated water from production processes to the surrounding area. The paper will, based on surveys answered by an IKEA supplier and four of IKEA’s sub-suppliers of textile in India, present a multiple case study of possible multiple effects of projects undertaken to lower the increased cost of manufacturing with ZLD. Building on the multiple case study, and marrying it with the knowledge of the multiple benefits of energy efficiency improvements, the Value Added Water (VAW) tool, and the rebound effect, this paper constructs and offers a Multiple Effects Framework (MEF) for measures taken in factories as a response to the increased cost of manufacturing with ZLD. The framework handles both quantifiable and non-quantifiable multiple effects of measures taken, such as changes in resource use (water, energy, chemicals, materials), productivity and work environment. The MEF aggregates a more comprehensive picture of the overall effects of measures taken to adapt to the increased costs associated with ZLD in the textile supply chain, and can to a certain extent be applied to other factories facing a future mandate for ZLD. When changed accordingly, the framework can also be applied to other situations and industries as a decision-making and evaluation tool. In order to deepen the understanding of customer expectations and future trends, interviews were made with IKEA co-workers and a consultant involved with the factories investigated. Lessons learnt by IKEA and the consultant regarding ZLD implementation and the resource nexus are presented for internalization by factories, customers and authorities.

This dissertation assesses the long-term technological and policy implications of adapting to water constraints and climate change impacts in the energy sector. Energy systems are increasingly vulnerable to climate change and water resource variability. Yet, the majority of long-term energy infrastructure plans ignore adaptation strategy. New analytical approaches are needed to address the spatial and temporal scales relevant to both climate change and water resources. The research in this dissertation overcomes these challenges with improved engineering-economic modeling. Specifically, the conventional systems-engineering energy technology planning framework is extended to incorporate: (1) robust capacity decisions in the electricity sector in light of impacts from hydro-climatic change and uncertain environmental performance of technology options; (2) an endogenous, spatially-distributed representation of water systems and feedbacks with energy demand; and (3) multi-objective decision-making. The computational modeling framework is applied to four regional case study analyses to quantify previously unaccounted for policy-relevant interactions between water, energy and climate systems. Application of the robust adaptation planning framework to the power system in British Columbia, Canada, reveals technology configurations offering long-term operational flexibility will be needed to ensure reliability under projected climate change impacts to provincial hydropower resources and electricity demand. The imposed flexibility requirements affect the suitability of technology options, and increases the cost of long-term electricity system operation. The case study analysis then focuses on the interaction between groundwater conservation and concurrent policy aimed at reducing electricity sector carbon emissions in the water-stressed country of Saudi Arabia. Application of the novel water-energy infrastructure planning framework reveals that transitioning away from non-renewable groundwater use by the year 2050 could increase national electricity demand by more than 40 % relative to 2010 conditions, and require investments similar to strategies aimed at transitioning away from fossil fuels in the electricity sector. The research in this dissertation demonstrates the crucial need for regional planners to account for adaptation to climate change and water resource constraints when developing long-term energy strategy. / Graduate

The economic development challenges facing second-tier city-regions in the United Kingdom reflect a critical dimension of policy debates concerning spatial rebalancing. The integration of multi-location firms at second-tier territorial contexts is an important aspect of rebalancing narratives, and this thesis examines what such integration may entail for the economic development of these places. Given the label of the “firm-territory nexus” by other economic geographers (Dicken and Malmberg, 2001), integration brings into focus a complex set of factors, processes and conditions. In order to grapple with and order such complexity, the conceptual framework of city-region absorptive capacity has been proposed and developed in this research. Four case studies across two second-tier UK cities, Edinburgh and Manchester, comprising interviews with elites and the collection of extensive documentary material, provides the empirical material for framework development. The research hinges on an analytical process that: first, deploys the functional form of “absorptive capacity” to provide language and broad parameters by which to approach the empirical object; and second, generates abstract categories from the empirical data to flesh out a contextually sensitive conceptual framework. Network position relative to London and labour appear as important integrating mechanisms across the case studies, though the conceptual framework demonstrates contingencies in terms of territorial and relational processes, shifting moments of structure and agency, and the overlapping institutional mosaics at play. By providing portraits of city economies in the middle ground of global economic networks, the need to articulate economic geographies of the “outside” and “inside” are also given emphasis.

Since the end of the Cold War, the concepts of development and security and the rise of the security-development nexus has proven to be important and is increasingly used in policy documents by institutions and states. This thesis aims to provide insight on how security and development concepts and their nexus have been used in governments’ foreign policies. Previous research has been focused on multilateral organizations and aid officials and how they have been influenced by the security-development nexus, but a comprehensive analysis on what drives financial and political support has been limited. Therefore, there is a gap that this thesis aims to fill. Methodologically, this thesis uses a text analysis of policy frameworks published by the government of Sweden regarding aid, development cooperation and humanitarian assistance of the years 2013/14 and 2015/16. An abductive reasoning was made with the help of the chosen analytical frameworks in this study. This study concludes that Swedish policy frameworks are using redefinitions of the concepts security and development which results in more broaden use of the concepts. This use of the concepts creates clear policy frameworks, but the policy frameworks do in some passages not elaborate what kind of security that reinforces what kind of development or what kind of definition of security or development that it is referring to.  This leaves the reader with a great room for interpretation that could eventuate in many different outcomes and versions. Furthermore, security and development are presented as concepts which are mutually reinforcing each other and used in four different narratives, or nexuses, when mapping out the security-development nexus.

A presente dissertação se propõe à qualificação do conjunto de contratos celebrados em financiamentos organizados sob a modalidade project finance como verdadeira coligação contratual, apresentando determinadas consequências jurídicas daí decorrentes, bem como sublinhando a correlação positiva entre tal compreensão e o estabelecimento de um panorama institucional adequado, que contribua para o desenvolvimento econômico. Ocupa posição nuclear no estudo o reconhecimento de que os negócios jurídicos concluídos no âmbito de tais programas de financiamento consistem, de fato, em instrumentos aptos a operacionalizar um arranjo de alocação de riscos que reflita a racionalidade econômico-financeira do projeto, garantindo, assim, sua viabilidade. Portanto, muito embora conservem sua autonomia estrutural e desempenhem, cada um deles, sua função econômico-social individual, contribuem, simultaneamente, para a realização de um fim concreto ulterior - operação econômica subjacente -, que coincide com o desenvolvimento e operação do empreendimento financiado. Pretende-se, igualmente, oferecer subsídios para que aqueles que sejam chamados a decidir sobre questões versando a temática abordada o façam de forma crítica e coerente, sem descuidar das motivações, econômicas e jurídicas, que subjazem ao project finance. / This thesis aims to qualify the nexus of contracts entered into in project financings as connected contracts, presenting certain legal effects which hence arise, as well as highlighting the positive correlation between such qualification and the establishment of an adequate institutional framework that contributes to economic development. It is fundamental to the study the acknowledgment that contracts entered into in such financings are, in fact, mechanisms that allow for the operationalization of a given risk allocation structure which, in turn, reflects the project\'s economic and financial rationale, therefore assuring its bankability. Accordingly, even though each contract conserves its structural autonomy and plays its own economic and social function, they all simultaneously contribute towards the achievement of a further concrete goal - an underlying economic transaction -, identified with the development and operation of the financed venture. Nonetheless, it intends to offer subsidies so that those called upon to decide issues related to the subject can fulfill their duties in an argumentative and coherent manner, without neglecting project finance\'s underlying economic and legal motivations.

Notions of connectivity and relationality increasingly pervade theories, discourses and practices of environmental governance. Recently, the concept of the 'resource nexus' has emerged as an important new framework that emphasises the interconnections, tensions and synergies between sectors that have traditionally been managed separately. Part of a broader trend towards integrated environmental governance, nexus thinking rests on the premise that the challenges facing water, energy, food and other resources are inexorably connected and contingent. Although presenting itself as a radically new framework, the nexus discourse in current form is techno-managerial in character, profoundly de-politicising, and reinforces neoliberal approaches to environmental governance. At the same time, the 'material turn' in social science research has re-engaged ideas of social, political and material relationality to understand the complexity and heterogeneity of the socio-natural condition in the twenty-first century. Although theoretically and ontologically diverse, the fields of political ecology, assemblage thinking and infrastructure studies all critically interrogate the politics of relationality. Mobilising an urban political ecology framework, and drawing on notions of emergence and distributed agency from assemblage thinking, this research examines the politics of the water-energy nexus through a critical analysis of the extraordinary emergence of seawater desalination as a significant new urban water supply for Southern California, USA, and Baja California, Mexico. Research was conducted in the San Diego-Tijuana metropolitan region, where a large desalting facility has recently been completed to supply San Diego with purified ocean water, and a larger 'binational' facility is planned in Mexico to supply both sides of the border. The research makes three broad contributions. First, to understand desalination as emerging from the historical coproduction and urbanisation of water and energy in the American West. Second, to examine the transitioning environmental politics concomitant with calls for greater understanding of interrelationality. And third, to interrogate the efficacy of technology in reconfiguring the co-constitution of water, energy and society.

Controversy in transboundary rivers usually arises due to a lack of inclusive agreement and cooperation between the basin countries. Originating from Ethiopia, the Blue Nile River contributes most of the Nile River water making it vital for water, energy, and food security at downstream Sudan and Egypt. In 2011, the Ethiopian government announced the construction of the Grand Ethiopian Renaissance Dam (GERD) along the Blue Nile 40 km away from the Sudanese borders. The dam will be the biggest in Africa and seventh-largest in the world producing 6,000 Megawatts of electricity with a reservoir volume of 74 billion cubic meters. Great concerns were raised on the impact of this megaproject for downstream countries due to the expected changes in water quantity and quality. Different studies were published regarding the potential impacts of this dam on the Eastern Nile countries. However, these studies have usually focused on one aspect of the impact (e.g. hydropower, agricultural projects, water use) despite the connection that exists between these sectors. This research aims to investigate the impact the GERD operation will have on Sudan in terms of WEF security and sustainability. The study uses the WEF security nexus framework that addresses the interconnectedness between these sectors instead of treating them in silos. A sustainability assessment is also carried out to analyze the impact of the dam operation on the environmental, social and economic areas in Sudan. The study first looked into the current state of Sudan’s WEF security nexus and highlighted the vulnerabilities that exist within these sectors. Then an analysis of the GERD operation was carried out and the results showed that water regulation and sediment reduction will reflect positively on Sudan as it will enable for expansion in agricultural projects, increase hydropower production, and provide flood control. Some negative impacts, however, are to be expected especially during the impounding phase from water level reduction and change in river characteristic which will greatly affect the environment and society downstream. The safety of the dam was found to be the biggest threat to Sudan’s security, as the case of dam failure will have catastrophic consequences for the country. The study concluded that an increase in cooperation between the Eastern Nile countries will decrease the downstream negative impacts of the GERD and increase its overall benefits ultimately leading to sustainability, peace, and welfare for these countries. Sudan also needs to take measures in accommodating the new flowing conditions including reoperation of the Sudanese dams and mitigation strategies for the potential negative impacts.

Water and electricity are fundamentally linked. Policy reforms in both industries, however, do not appear to acknowledge the links nor consider their wider implications. This is clearly unhelpful, particularly as policy makers attempt to develop effective responses to water and energy issues, underpinned by prevailing drought conditions and impending climate change. Against this backdrop, this research has comprehensively analysed the links between water and electricity – termed water-energy nexus – in the context of New South Wales. For this purpose, this research has developed an integrated methodological framework. The philosophical guidance for the development of this framework is provided by Integral Theory, and its analytical foundations rest on a suite of research methods including historical analysis, inputoutput analysis, analysis of price elasticities, and long-term scenario analysis. This research suggests that the historical and inextricable links between water and electricity, in the absence of integrated policies, has given rise to water-energy trade-offs. In the electricity industry, water-intensive coal-fired power stations that dominate base-load capacity in the National Electricity Market has resulted in intra- and inter-jurisdictional water sharing tradeoffs. Intermediate and peak demand technologies, suchas gas-fired, cogeneration and renewables, however, would significantly reduce the industry’s water consumption and carbon emissions. Drought and climate change adaptation responses in the water industry are likely to further increase electricity demand andpotentially contribute to climate change, due to policies that encourage investment in energy-intensive technologies, such as desalination, advanced wastewater treatment and rainwater tanks. Increasing electricity costs due to water shortages and the introduction of emissions trading will futher increase water and electricity prices for end users. Demand management strategies in both industries will assist in curbing price increases, however, their effectiveness is lessened by investment in water- and energy-intensive technologies in both industries. The analysis also demonstrates that strategies to reduce water and electricity consumption of ‘other’ production sectors in New South Wales is overwhelmingly dependent on how deeply a particular sector is embedded in the economy, in terms of its contribution to economic output, income generation and employment growth. Regulation, demand management programs, and water pricing policies, for example, that reduce the water and energy intensity of agriculture and key manufacturing sectors are likely to benefit the wider economy and the Environment. The future implications of the water-energy nexus are examined through long-term scenario analysis for New South Wales for 2031. The analysis demonstrates how policy decisions shape the domain for making philosophical choices by society - in terms of the balance between relying on alternative technologies and market arrangements, with differing implications for water and electricity use, and for instigating behavioural change. Based on these findings, this research puts forward a range of recommendations, essentially arguing for reorienting existing institutional arrangements, government measures and industry activities in a way that would encourage integration between the water and energy policies. Although the context of this research is New South Wales, the findings are equally relevant for other Australian states, which share the same national water and energy policy frameworks. Further, the concepts and frameworks developed in this research are also of value to other countries and regions that are faced with the task of designing appropriate policy responses to redress their water and energy challenges.

<p>Background: The business market today is characterized by tough competition amongst the competitors to capture consumers’ interest and money. One marketing tool companies can use to achieve this is the company’s image. The customer buys not only a product, but also the image that the company or the product is associated with. To reach the desired corporate image companies need to be aware of the signals they are sending out and how and what to communicate to the market. They need to look within themselves and their internal factors, since the signals are created within the company. </p><p>Purpose: To examine how different structures of organisations can influence a company’s internal image and thereby leave a contribution to the knowledge of a business’ internal image. </p><p>Research Method: Empirical studies have been accomplished through interviews with employees on different positions at Nexus. A case study approach was used to give a more complete depiction of the company. </p><p>Conclusion: A splinter within an organization can be seen through its image, which affects the external image. Uncertainty in the structure of the organization will also be exposed to the environment, which will lead to a splintered picture of the organization. Two important factors when creating an image are business culture and information/communication. These factors will together generate a united transmission of the company and its values.</p>
