There are some problems in China’s agricultural water resources, such as low per capita consumption and uneven spatial and temporal distribution. It is urgent to speed up the reform of water rights trading mode. Based on the market orientation and the experience of the United States and Australia, this paper studies the effectiveness of China’s agricultural water rights trade. Firstly, the characteristics of “quasi-market” should be clarified. Secondly, under the market mechanism, this paper analyzes the mechanism of the impact of economic incentives of trading subjects, reasonable delimitation of trading prices and multiple participation of institutions and departments. Furthermore, the factors that affect the efficiency are deeply analyzed. At last, the paper provides some suggestions on the construction of a trading mechanism with Chinese characteristics from the aspects of right confirmation registration, pricing mechanism and supervision regulations, to provide decision support for agricultural water rights management system.

Few would doubt the need, in today's world, to promote behaviours that actively conserve environmental resources. At a general level, this often involves encouraging behaviours that involve a short-term cost for the individual in order to avoid a long-term negative outcome for the community. Examples of such behaviour are, taking the trouble to turn off lights to save electricity and fixing leaking taps to conserve water. It is these latter kinds of behaviours, namely those associated with the efficient use of water resources, which are the focus of this paper.Faced with the high economic and practical costs of attempting to supply unlimited amounts of water for the Melbourne metropolitan area, the Board of Works has sought, by a number of means, to persuade its consumers to use water more efficiently. One aspect of its strategy was to promote water conservation within the educational curriculum by designing various educational materials and programs for different school levels. These and other promotional materials were made available to schools in the Melbourne metropolitan area in 1988. Prior to the distribution of this material, the data reported in this paper were gathered as the first stage of a longitudinal evaluation of the Board's education strategy.The assumption underlying the Board of Works' educational program was that behaviour change is preceded by changes in knowledge. For example, it was assumed that a person, knowing something about the water cycle, and the system by which water is fed into our taps, would believe that it is important not to waste water. The result would be active water conservation in daily life. Some basis for this assumption has been provided by the report on domestic water use in Perth, Western Australia (Metropolitan Water Authority, 1985), where knowledge and attitudes were found to be predictors of actual water consumption. Such an assumption is based in a general way on a cognitive or information processing model of behaviour change, in which changes in behaviour are seen as proceeding from changes in relevant information or knowledge. This cognitive model is the basis for many social education programs both in schools and in the community. For example, the Quit Campaign and the AIDS campaign have both used strategies that aimed to inform the public about particular health-related behaviours.

Abstract We present the first analysis of water use in the Australian economy to account for inter-state trade, exports and consumption patterns, across all economic sectors and incorporating a temporal analysis. This is achieved by using the environmentally extended input-output technique, combining state-level input-output and water accounts from the Australian Bureau of Statistics. Results show that the three big eastern economies (New South Wales, Victoria, Queensland) rely mostly on water used within their jurisdictions. Approximately one-third of water consumption is for exported commodities, with the biggest export flows of virtual water being associated with agricultural production. Comparing results across the years (2000–2011), the water consumption associated with the provision of goods and services has decreased by 32% for exports, and by 38% for domestic markets. To date in Australia, the focus for improved trans-boundary water management (within Australia) has been on improved mechanisms for sharing physical allocation of water; these results provide the trans-boundary economic dependencies related to water availability. Recent innovations in the compilation of economic input-output models create an opportunity to progress this analysis, exploring in detail the economy–water interlinkages. It is our intention that the paper shows the value of analysing water flows using the multi-regional input-output techniques.

Highly frequented big events play an increasing role in modern, leisure-oriented society. If you wish to host world exhibitions, trade fairs, sports events or other fairs you not only have to aim for sufficient visitors to match your economic expectations. As well as extensive use of service industries, the provision of a sufficient and reliable water supply, a wastewater disposal and sanitary equipment is crucial. In this article advice to prepare for big events and performance indicators for the consumption of venues will be given. Furthermore predictions on water consumption, ways to reduce the consumption and contractual aspects will be touched on.

Abstract The main topics presented in this paper are following:1 Essence and the tools of the economic mechanism of management of water resources; 2 Taxes on water consumption; 3 Tariffs for services of water supply and sewerage; 4 administrative penalties for infringements of use and protection of water resources; 5 The grants for the rational use and protection of water. In the Dniester Basin have been concentrated the majority of water resources, of urban, industrial and agricultural centers. Thus, this basin holds over 90% of water consumption, most of which are captured from surface sources and used by industrial enterprises from the left bank of Dniester, especially by Thermoelectric Plant (TEP) from Dnestrovsk. On the right bank of Dniester it is noted communal enterprises, agricultural and food industry, and in most of the localities water is captured from groundwater sources. Actual amount of water tax is very low, which conditioned the increased of water consumption and irrational use of these limited resources

Current progress of water accounting was reviewed systematically in the paper. The result of water accounting is outstanding in some countries abroad, like Australia, South Africa, and European Union (EU) countries. In China, the exploratory research appeared in the 1990s. The study showed that theoretical framework of water resource accounting is basically formed, and research on physical accounting of water resources is abundant. However, some aspects, such as estimate of value, compilation of water economy accounts, and coupling between water resources accounting and national economic accounting system need improvement, which can provide methodological support for the water accounting system and valuable reference for integrated environmental economic accounting system (SEEA).

Abstract. Within the article, the sources of water pollution of Ukraine as a result of the intensification of agricultural activities in Ukraine are systematized and substantiated, adjusting measures on water use to prevent the deterioration of water quality, negative consequences of irrational use of water resources by the agricultural sector are considered. It is argued that deterioration factors of the hydrosphere state as a result of the agricultural sector can be significantly reduced by using the following actions: combination of crop production with animal production, which eliminates the problem of waste, promotes more efficient use of the fodder use; circulating water supply system, in which the used water after cleaning is not discharged into the environment, but is used repeatedly; local seeds for crops production and local breeds in animal husbandry; bans or restrictions on the use of the plants’ protection products insanitary zones of the water supply sources; limiting the maximum rates of the pesticides consumption, frequency and timing of their application in organic production; drip irrigation; collecting rainwater for irrigation from built in own reservoirs; cultivation of agricultural crops that are suitable for the climate; practicing a mulching system to preserve moisture in the soil; actual functioning of water protection zones along rivers and water objects, reduction of water losses during transportation to water consumers, creation of artificial reserves of underground water due to filtration losses near bulk reservoirs and main channels, which should increase the productivity of water intakes, etc. It is determined that for the introduction of rational waterconsumption and water use in long term, the improvement of the environment quality is possible by greening the needs in order to eliminate the deformed value system. The pace, structure and culture of the consumption should be formed in accordance with ecological restrictions, reducing the load on the ecosystem, balanced consumption, finding a balance between the economic well-being of the current generation and the availability of quality water resources for future generations

Economic growth is the main goal of the global economy. However, increasing economic growth often results in increased CO2 emissions and encourages environmental degradation. This study analyzes the impact of industrialization, consumption of fossil energy, economic growth, and population activities on CO2 emissions in upland water catchment areas. Data analysis using panel data regression, in a span of 20 years. The results of the study show that economic factors, namely industrialization and consumption of fossil energy, are the main determinants of increasing CO2 emissions. Meanwhile, social aspects such as education, waste generation, and population have no effect on CO2 emissions.

Full textAbstract:
Introduction. Landfill leachates contain highly concentrated organic products of waste degradation and mineral salts. Concentrations of organic matter demonstrate high COD values up to 5,000 mg/l, concentrations of ammonium ions reach 2,500 mg/l, while the total salt content may reach 15,000 mg/l. Two to three reverse osmosis treatment stages may be needed to produce the water that meets effective regulations governing the composition of water discharged into the environment. Also, high salt content and COD values dramatically reduce the membrane capacity. The co-authors explored the use of nanofiltration membranes at the first stage of the leachate treatment in an effort to reduce membrane operation costs.
Materials and methods. The experiments, conducted within the framework of this research undertaking, allowed to identify a change in the concentrations of contaminants, dissolved in the leachates of reverse osmosis and nanofiltration membranes, as well as the reduced capacity of membranes at each stage of treatment. The co-authors have studied the alternative methods that may ensure maximal reduction of the concentrate consumption in the process of leachate treatment. Principal dependencies, derived as a result of the research, enabled the co-authors to identify the concentrate consumption rates depending on the extent of treatment focused on ammonium ions. The co-authors describe the methodology employed to identify the area of membranes at each treatment stage depending on the leachate composition.
Results. Calculations of operating costs are provided for three compositions of leachates, typical for the Moscow region, depending on the treatment methodology and further recovery of membrane concentrates.
Conclusions. Nanofiltration membranes can be used at the first stage of the landfill leachate treatment in the case of high COD and salt content. The application of nanofiltration membranes allows to reduce the concentrate consumption rate and cut operating costs. A new technology is developed to split the concentrate into two flows: the flow that has a high organic matter content, and the flow that has a high content of mineral salts, sodium and ammonium chlorides in order to facilitate the recovery of the concentrate.

Reducing consumption of free sugars, such as those found in high concentrations in manufactured products such as sugar-sweetened beverages (SSBs) and 100% fruit juices, is a global public health priority. This study aimed to measure prevalence of widely available pre-packaged non-alcoholic water-based beverages (carbonated sodas, sports drinks, energy drinks, artificially-sweetened sodas, fruit juices (any type), and bottled water) and to comprehensively examine behavioral, environmental, current health, and demographic correlates of consumption. A cross-sectional, nationally-representative population survey of 3430 Australian adults (18+ years) was conducted using computer-assisted telephone (mobile and landline) interviewing. Past week prevalence of pre-packaged drinks containing free sugar was 47.3%; daily prevalence was 13.6%. Of all the pre-packaged drinks assessed, consumption of fruit juices (any type) was the most prevalent (38.8%), followed by bottled water (37.4%), soda (28.9%), artificially-sweetened soda (18.1%), sports drinks (8.1%), and energy drinks (4.2%). Higher soda consumption was associated with males, younger age, socio-economic disadvantage, frequent takeaway food consumption, availability of soda in the home, obesity, and a diagnosis of heart disease or depression. A diagnosis of Type 2 Diabetes was associated with increased likelihood of consuming artificially-sweetened sodas and decreased likelihood of consuming sugar-sweetened soda. SSB consumption is prevalent in Australia, especially among young adults and males, foreshadowing continued population weight gain and high burdens of chronic disease. To reduce consumption, Australia must take a comprehensive approach, incorporating policy reform, effective community education, and active promotion of water.

Full textAbstract:
Large increases in water demand with very little recharge have strained Libya’s groundwater resources, resulting in serious declines in water levels and quality, especially along the Mediterranean coast where most of the agricultural, domestic and industrial activities are concentrated. To meet these increases, Libya turned to desalination as a supplementary water resource as early as 1964. Both thermal and membrane desalination technologies have been used. This study shows that the problem of water scarcity is likely to increase further in the future. This study has three aims: first, to estimate the historical relationship between population growth and the various uses of water; second, to forecast water consumption according to the various uses; third, to estimate the elasticities of water demand and examine the effect of price, income, population and temperature on water demand in Libya in the short and long-run. To achieve these aims, an econometric model of Libyan water demand is constructed and estimated for the period 1975-2005, using the Box-Jenkins approach to forecast water demand and the Engle-Granger two-step approach to estimate the short and long-run elasticities of water demand. As a result this study provides considerable information for policy makers concerning current and future Libyan water demand. By examining the relationships between population growth and the future consumption of water in Libya, it is possible to reach the following conclusions. • Population growth in Libya will be very high. • Population elasticities for water demand are elastic for agricultural, domestic and industrial purposes. Water demand for all purposes is extremely elastic. • Most of the population and agricultural lands are concentrated in the northern part of the country. • The Libyan economy depends heavily on underground water. • In Libya, as a whole, water demand will increase. Available water in 2020 will be less than half of water demands, implying an increase in the water scarcity problem over time. • The short and long-run price elasticties are negative, suggesting that there is an inverse relationship between water demands and price. Also, these elasticities indicate that water use is generally inelastic with respect to price. • The income elasticities are all positive in the short and long-run. This result accords with demand theory, implying that water is a normal good. • The estimation results suggest that, in the long-run, water demand for agricultural, domestic and industrial use is highly elastic for population and inelastic for price and income. • The short-run elasticities are less than the long-run elasticities, as economic theory suggests. Also, all elasticities in the short-run are less than one. This implies that water demand is inelastic in the short-run.

Thesis (PhD)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Concerns about the sufficiency of freshwater supplies and the impact of water shortages have placed sustainable water management on the global agenda. This is particularly relevant in South Africa, a country with precipitation rates well below the global average and water resources that have become highly polluted. The scarcity of water for consumption use and of unpolluted water bodies as recreational and environmental good highlights the need for an economic analysis of these issues. This dissertation investigates some economic aspects of water management in the South African context in two distinctive parts. Part One (Chapters 2 to 5) aims to provide an understanding of urban water demand and analyses water pricing as demand management tool. Part Two (Chapters 6 and 7) analyses the values people attach to water resources for recreational and environmental purposes. Quantitative methodological approaches are predominantly used to inform an economic perspective on water demand management. The extent of water scarcity is discussed in Chapter Two. South Africa is approaching physical water scarcity, but many poor households do not yet have access to water and basic sanitation facilities, i.e. there is also economic water scarcity. Given this background, Chapter Three focuses on water demand management as part of an integrated water management approach. The role of water prices is discussed, in particular the Increasing Block Tariff (IBT) structure which is predominantly used in South Africa. Chapter Four estimates the price elasticity of demand for water using household water consumption records obtained from the City of Cape Town (CCT). A distinctive feature of this case study is a survey undertaken to collect household information on demographic and water-use characteristics, as water databases are severely lacking in South Africa. The results show water demand to be mostly price inelastic, which concurs with findings from international empirical literature. Furthermore, higher-income households are found to be more sensitive to price changes, thus some reduction in water consumption can be achieved by increasing marginal prices at the upper end of the IBT structure. Chapter Five analyses the IBT structure as a redistributive tool. Particular attention is given to the Free Basic Water policy of South Africa, which allows each household to receive six kilolitres of water free per month. Empirical modelling indicates that the IBT structure in its current form holds limited benefits for the poor, given the state of service delivery in South Africa: the lack of access to the water network prevents the poorest households from being the recipients of the cross-subsidisation occurring in an IBT structure. Part Two studies urban water resources as recreational and environmental goods. The literature review of environmental valuation techniques in Chapter Six places particular emphasis on the Contingent Valuation Method. This method is applied in Chapter Seven, where the value of improving the environmental quality of a freshwater urban lake is analysed in a middle- to low-income urban area. Another survey was undertaken specifically for this purpose of gauging the willingness to pay for improved recreational facilities and water quality of Zeekoevlei. The results show that low-income households do attach value to urban environmental goods, a result which adds to our knowledge of willingness to pay for environmental goods in developing countries.
AFRIKAANSE OPSOMMING: Besorgdheid oor die toereikenheid van varswaterbronne en die impak van watertekorte het volhoubare waterbestuur op die wêreldagenda geplaas. Dit is veral relevant vir Suid- Afrika, 'n land met neerslagkoerse ver onder die wêreld gemiddelde en waterbronne wat hoogs besoedeld geword het. Die skaarsheid van water vir verbruik en van onbesoedelde waterbronne as ontspannings- en omgewingsproduk, beklemtoon die noodsaaklikheid vir 'n ekonomiese analise van hierdie kwessies. Hierdie proefskrif ondersoek sekere ekonomiese aspekte van waterbestuur in die Suid-Afrikaanse konteks, in twee dele. Deel Een (Hoofstukke Twee tot Vyf) beoog om insig te verskaf oor die stedelike vraag na water en analiseer die prys van water as 'n vraagbestuursmaatstaf. Deel Twee (Hoofstukke Ses en Sewe) ontleed die waarde wat mense heg aan waterbronne vir ontspannings- en omgewingsdoeleindes. Kwantitatiewe metodologiese benaderinge word hoofsaaklik gebruik om 'n ekonomiese perspektief op watervraag bestuur toe te lig. Die omvang van waterskaarsheid in Suid-Afrika word in Hoofstuk Twee bespreek. Hierdie hoofstuk dui aan dat Suid-Afrika besig is om fisiese waterskaarste te bereik, maar die land het ook baie arm huishoudings wat nog nie toegang tot water en basiese sanitasiefasiliteite het nie, dw.s. wat daar is ook ekonomiese waterskaarsheid. Gegewe hierdie agtergrond, fokus Hoofstuk Drie op watervraagbestuur, as deel van 'n geïntegreerde waterbestuursbenadering. Die rol van waterpryse word bespreek, veral die Stygende-Blok-Tarief (SBT) struktuur wat grotendeels in Suid-Afrika gebruik word. Hoofstuk Vier bepaal die pryselastisiteit van vraag vir water met behulp van huishoudelike waterverbruiksdata, verkry vanaf die Stad Kaapstad. 'n Kenmerkende eienskap van hierdie gevallestudie is die ingesamelde huishoudelike inligting oor demografiese en waterverbruik-eienskappe, aangesien daar ‘n groot tekort aan water-databasisse in Suid- Afrika is. Die uitslae toon dat watervraag meestal prysonelasties is, wat ooreenstem met bevindinge van ander empiriese literatuur. Verder word gevind dat hoё-inkomste huishoudings meer sensitief is vir prysveranderinge. Dus sal 'n afname in waterverbruik bewerkstellig kan word deur marginale pryse aan die hoёr kant van die SBT struktuur te verhoog. Hoofstuk Vyf ondersoek die SBT struktuur as 'n effektiewe herverdelingsmaatstaf. Spesifieke aandag word aan die Gratis Basiese Water-beleid van Suid-Afrika geskenk, wat voorsiening maak dat elke huishouding ses kiloliter water per maand verniet ontvang. Die bevindinge van empiriese modellering is dat die SBT struktuur, soos dit tans in Suid-Afrika toegepas word, beperkte voordele vir die armes inhou, gegewe die huidige stand van watervoorsiening in Suid-Afrika. As gevolg van die agterstand met betrekking tot toegang tot water, ontvang die heel armes nie die voordele van kruissubsidiёring wat plaasvind onder 'n SBT struktuur nie. Deel Twee bestudeer stedelike waterbronne as ontspannings- en omgewingsprodukte. Hoofstuk Ses verskaf 'n literatuur oorsig oor omgewingswaardasie tegnieke, met 'n spesieke fokus op die Kontingente Waardasie-metode. Hierdie metode word in Hoofstuk Sewe toegepas, waar die waarde van verbeteringe in die omgewingskwaliteit van 'n varswatermeer in 'n middel- tot lae-komste stedelike gebied ondersoek word. Nog 'n opname is gedoen met die doel om die bereidwilligheid om te betaal vir verbeterde ontspanningsfasiliteite en die waterkwaliteit van Zeekoevlei te meet. Die bevindinge toon dat lae-inkomste huishoudings wel waarde heg aan stedelike omgewingsprodukte.

Full textAbstract:
Balancing water demand and supply in South Africa involves high levels of uncertainty. The Department of Water and Sanitation (DWS) is responsible for making decisions to either increase water supply or decrease water demand so as to ensure that sufficient water is available, when and where it is needed. However, no retrospective analyses of such decisions have been found. One way to assess such decisions is to evaluate the associated costs and benefits thereof. Therefore the primary aim of this study is to evaluate the costs and benefits of selected water supply options, and of the decision-making associated with those options. In order to achieve this purpose, four case studies were analysed within a mixed-methods research paradigm, which used both quantitative and qualitative methods, including unit reference value (URV) analysis, inter- and intra-case analysis and content analysis to examine the success of the decisions made. The four case studies were conducted on the Inyaka, Nandoni, Berg and De Hoop dams and their catchments. Firstly, estimated and actual project costs were compared using unit reference analysis and inter-case analyses. Secondly, the reduction of mean annual runoff (MAR) caused by invasive alien plants (IAPs) and the cost of clearing them in the dam catchments were evaluated using inter-case analyses. Information thus gathered was used together with data from DWS documentation and the results of interviews with ten key specialists, to analyse the decision-making process that led to the decision to build De Hoop Dam (the most recent case study). The rational decision-making model (RDMM) was used as a framework within which to analyse and evaluate this decision-making process. This study has also demonstrated how the RDMM can be used to assess decision-making associated with water supply development. The results of this study show that there is considerable variation of estimated costs (at the time that the decision to build the dam was taken) in relation to the actual costs of building the dams and that Ministers were not put in a position to understand the full long-term costs or the opportunity costs of the proposed dams. Furthermore, the most recent IAP data (2008) shows that the impact on water security by IAPs could not offset the water security resulting from building each of the four dams. However, if IAP management is not continued in these catchments, the projected reduction of MAR by IAPs will compromise water security within 45 years. Given the almost exponential spread and densification of IAPs, together with their long-term impact on MAR and increased costs of controlling them, it is clear that IAP management should have been factored into water supply decision-making from the outset. In the analysis of the decision to build the De Hoop Dam, the results show that while the decision-making process that culminated in the decision to build the dam did not follow the steps of the RDMM, DWS appears to have followed a somewhat similar approach. It was found that while there was a need for the provision of additional water in the Olifants catchment, this need was overstated and the resulting overestimation caused the scale and size of the dam to be larger than it could and probably should have been. Additionally, it appears that DWS‘s decision to build the De Hoop Dam themselves, rather than having it built by the private sector, may have been less than optimal. It is recommended that, in future decision-making, DWS needs to incorporate multiple alternative options into the same solution, and to ensure that decision-makers are put into a position to make informed decisions, including adequate consideration of externalities. Furthermore, DWS needs to employ decision-making models such as the RDMM to facilitate retrospective analyses to improve their institutional knowledge. Keywords: water resources management, dams, invasive alien plants, decision-making, unit reference values, rational decision-making model.

Cada vez mais as atividades econômicas e recreativas demandam recursos naturais para o seu desenvolvimento. No entanto, são inevitáveis os impactos negativos causados sobre o meio ambiente e a discussão da sustentabilidade, como condição básica e indispensável para assegurar a continuidade desses processos. Esta pesquisa teve como objetivo analisar as informações de hóspedes sobre práticas ambientais relacionadas à gestão, conservação e ao uso da água em meios de hospedagem, em conformidade com a NBR 15401. Para tal, foram aplicados 166 questionários a hóspedes de três Meios de Hospedagem (MHs) do Roteiro Turístico Termas e Longevidade, em duas semanas com eventos na região. Os dados indicam que 38% dos sujeitos realizam o controle do consumo de água nos MHs em que se hospedam; 32% afirmam que a sua maior preocupação está relacionada ao desperdício e à contaminação da água; 15,1% indicam que os MHs em que se hospedam apresentam medidas de racionalização de uso de água, porém, de maneira isolada e não na forma de programas ambientais. As principais medidas, destacadas pelos hóspedes, implantadas nos MHs, são as torneiras com fechamento automático ou com restritores de vazão, reuso de toalhas de banho e troca de roupas de cama em dias alternados. Os dados também revelam que os MHs, eventualmente, apresentam informações aos hóspedes sobre a racionalização e a minimização no consumo de água e outros recursos naturais. Os resultados da pesquisa sinalizam medidas adotadas por hóspedes e MHs relacionadas à gestão da sustentabilidade, em especial a gestão dos recursos hídricos. Como continuidade, sugerem-se novos estudos sobre a gestão ambiental nesses empreendimentos, sobretudo em relação à participação dos hóspedes, colaboradores e gestores, identificando suas informações e atitudes em prol da minimização do consumo de água e do processo de construção do turismo sustentável.Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2016-11-28T15:56:14Z No. of bitstreams: 1 Dissertacao Cleomar Antonio Zocholini.pdf: 2204441 bytes, checksum: dbbd9933f095ccc0ac89c4e353c9e3b0 (MD5)

Recreational and economic activities require natural resources for theirs development, more and more. Nevertheless, negative impacts on environment and the sustainability discussion as a basic and indispensable condition are unavoidable, to ensure the continuity of these processes. This research aims to analyze the guest information about related environmental practices to the management, conservation and at the water use in lodging means, according to NBR 15401. In that case, 166 questionnaires were applied to guests of three MHs of the Longevity and Thermal Baths Tourist Route in two weeks with events in the region. The data indicate that 38% of the interviewees accomplish the water consumption control in the MHs where they are guests; 32% say that theirs biggest concern is related to waste and water contamination; 15,1% indicate that the MHs where they are guests introduce water use rationalization measures, but from isolated manner and not in the environmental programs shape. The detached main measures by guests implanted in the MHs are automatic stopcock or flow restrictors, bath towels reuse and bedclothes replace in alternated days. Occasionally, the data also reveal that the MHs introduce information to the guests about water consumption minimization and rationalization and others natural resources. The research results signalize adopted measures by guests and MHs related to sustainability management, specially the hydric resources management. As continuity, they suggest new studies about environmental management in those enterprises, especially in relation to the managers, collaborators and guests’ participation, identifying theirs information and attitudes in favor of the water consumption minimization and of the sustainable tourism construction process.

Full textAbstract:
Recent studies in water management policy point to insufficient recognition of water as a scarce commodity and the failure of pricing policies to account for the full economic costs of its production and supply. These costs include opportunity costs related to alternative uses of water; user costs associated with managing a scarce resource; and costs of externalities such as ground water depletion, pollution of waterways, and greenhouse gas emissions. Existing cost recovery based pricing policies may lead to inefficiencies such as excess consumption, under-investment in water infrastructure, and unnecessary subsidisation. Water scarcity can be managed in several ways. We can increase supply by investment in additional harvesting capabilities or new technologies such as desalination; we can constrain consumption so that existing supplies last longer; or we can use water in more efficient ways. As a short term measure, most countries adopt water restrictions when supplies are at critical levels. In the future, as urban population growth continues, harvesting of storm water and reuse of grey water may become part of a sustainable water management strategy. Water trading can be used to move water to where the marginal benefits are highest. Considerable water savings are possible through the use of more efficient industrial and domestic appliances. There is evidence in some countries that higher water tariffs have reduced consumption and promoted awareness of conservation. If we accept that water is an economic good, then we need to understand the costs related to its production, the patterns of its use, and the benefits received by different users. This thesis is an examination of theoretical and applied aspects of urban water pricing based on analysis of cost, demand, and welfare. We present theoretical models of cost that include economies of scale as a parameter, and a model of water demand by households with heterogeneous preferences. We determine marginal cost at the efficient level of output based on a partial equilibrium of supply and demand. We also show that when water is produced with increasing returns to scale, the efficient price will be insufficient to recover all costs, and therefore a form of second best pricing is required. We contrast conventional notions about water suppliers being cost minimisers with an alternative frontier model of cost efficiency. Two case studies examine the provision of water services under different forms of ownership. The first case study examines the provision of water to domestic households in the state of Victoria, Australia. The second case study examines the supply of water to the residents of Manila, one of the world’s largest cities that privatised its water service in 1997 under a form of concession agreement. A third case study derives an efficient cost frontier for a sample of water utilities from Asia and Australia and proposes a form of best practice pricing. The thesis concludes with a summary of the main results and policy conclusions, and ideas for future research.http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1289196

Nadolny, Andrew John. "Rethinking trade: developing and applying an explanation to the Australian water technology and management industry." 2004. http://repository.unimelb.edu.au/10187/7092.
Full textAbstract:
This thesis seeks to explain how trade develops, applying the ideas to the Australian water management and technology industry. Disparate explanations and gross generalisations at the macro-level of national economies have hindered the development of a unified theory of trade. While understanding trade at the macro-level is foundational, analysis at the level of the firm is necessary for a comprehensive understanding. Four main strands of explanation have been identified from the literature: competitive advantage and corporate strategy, innovation creation and acquisition, markets and networks, and state and institutional influence. The strands combined form a framework that can explain how and why trade occurs for firms in a particular industry. Innovation leads to competitive advantage which extends a firm’s spatial influence in the market. Networks interconnect the firm with its external environment. The state’s role is to facilitate various processes such as amplifying competitive advantage.The framework is applied to firms representing the Australian water technology and management industry. This industry is diverse, encompassing small and large firms, and specialist manufacturers and producer services. The diversity is ideal for testing a comprehensive explanation. In addition, the water industry - as a subsector of the environmental goods and services sector – is a potentially valuable export activity.
The empirical work demonstrates that rethinking trade involves insights from the various explanatory strands. Creating competitive advantage and innovation involves processes internal and external to the firm. In the water industry, competitive advantage is a multifaceted concept and can be created by firms possessing a specialist product or service, or having a cultural affinity with clients. Corporate strategies such as inter-firm alliances and intra-firm multinational linkages also reinforce competitiveness. While the size of firms has some influence on competitiveness, size and age do not determine propensity to export. The use of innovation proxies by manufacturing firms increases propensity to export. A weak correlation is revealed between R & D proportion and export proportion; however, there is no evidence of a correlation between the proportion of patents and export proportion. Innovation expressed as appropriate technology, or embedded in specialist services, provides a more convincing explanation of export activity. Localised linkages between related and supporting industries are not a prerequisite for creating competitive advantage or innovative activity. Network theory explains how competitiveness transmits across space. Networks link the internal environment of the firm with external determinants, and explain how actual export contacts are made. Once networks and trust are established, spatial separation is not detrimental to sustaining relationships between key actors.
The quantitative evidence does not reveal significant relationships between innovation, competitive advantage and trade. Qualitative factors explain these relationships more satisfactorily. Cultural affinity, appropriate technology and networks help firms create competitive advantage, leading to trade. The state has a strong indirect influence in facilitating trade and should be an important part of a theory.
Thus an explanation of trade must shift networks to central importance and de-emphasise the role of localisation economies. The concept of innovation also needs to extend beyond an interpretation confined to technological change. The limitation of these interpretations is that they only apply to one industry in a particular place. However, the framework is flexible enough to be adapted to other industries, with certain strands being emphasised and de-emphasised accordingly. The empirical findings also have practical implications for the development of trade and industry policy; for example, flexible industry assistance that facilitates the creation of international networks by small and medium-size firms

Full textAbstract:
Residential energy and water consumption depend on dwelling structure and the behaviour of residents. Aspects of residential behaviour can be derived from census data. Dwelling information is harder to obtain. Using both aerial and street-level views from Google mapping products, exterior dwelling characteristics were captured in each of 40 postal areas in and around Melbourne, Australia. This approach saved the time and cost of travelling to the widely spread suburbs and provided data not otherwise available. The census and dwelling data were compared with resource usage statistics in linear regression models. It was found that energy and water use are highly correlated, with socio-economic variables better explaining water consumption and dwelling structure factors better explaining energy consumption. Nevertheless, the proportions of households that include a couple with children and have a swimming pool provided useful models of variations in both energy and water use. Applications to planning through spatially explicit scenario testing were developed in ArcGIS ModelBuilder.

The use of pesticides is more intense and somehow erratic as it aims to face climate change consequences like drought and water scarcity. The rural population is getting to be more vulnerable to have these neurodegenerative diseases. However, intense food production and economic models mean also the use of heavy metals in many stages as well during the production and the consumption processes and practices. Evidence from experimental studies shows that such heavy metals may also be a factor for the occurrence of Parkinson's and Alzheimer's diseases. At least, the environmental lifestyle and, likely, genetic factors, individually and collectively, play a significant role in the etiology of the diseases.

The growing world population demands more production of proteins for healthy growth and prevention of protein-energy malnutrition. The animal proteins are not sufficient to meet the requirement of daily proteins intake. Furthermore, due to limited resources of animal number, land, water, environmental impact, the demand for vegetable proteins and sustainability have been increasing tremendously. This chapter will outline the demand scenarios of vegetable proteins, nutritional aspects, and technological challenges in product development and consumer acceptance. It will summarize the potential of vegetable proteins related to health and existing diseases. The consumption of vegetable proteins, development of product, economic, sustainability, and food safety aspects will be summarized.

Full textAbstract:
The growing population and rising standards of living lead to an increase of the consumption of many goods. Reducing municipal waste which is created in that process can result in a wide range of environmental, economic, and social benefits, such as reducing pollution in water and soil, greenhouse gas emissions and loss of valuable materials. The concept to solve this problem of municipal waste due to increased consumption can be found, among others, in circular economy (CE). Circular economy can be defined as “an economic system that is based on business models which replace the ‘end-of-life’ concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes to accomplish sustainable development” (Kirchherr, Reike, & Hekkert, 2017). A current trend in developed countries is closing the loop, moving from the concept of “end-of-pipe” waste management towards more holistic resource management (Wilson, 2007). Implementing the circular economy approach through waste management systems can pose multiple challenges while providing incentives to improve waste management infrastructure. However, this requires investments and may be perceived by many people as cost, not investment in future generations and their standard of living. The aim of this chapter is to initiate discussion on the positive aspects and barriers of circular economy development in the Polish waste management sector. In the case study described in the text, the roles of citizens, public institutions as well as enterprises are shown in selective waste collection processes as an important element of circular economy. In Poland, awareness of waste segregation and the importance of using recycled materials is not well-developed compared to many other EU countries, although this situation is beginning to gradually improve.

Full textAbstract:
One of the signature historical phenomena of the past 500 years has been the global expansion of European societies and their trans-Atlantic offshoots. The mercantile networks, commercial systems, and empires of conquest and colonization that formed the political and economic framework of that expansion involved the discovery and extraction of new mineral and agricultural resources, the establishment of new infrastructures of transport and communication, and the forcible relocation of millions of people. Another key component was the Columbian Exchange, the multiple transfers of people, animals, plants, and microbes that began even before Columbus, gathered pace after 1492, and were further fuelled as European settlement advanced into Africa, Australasia, and the Indian and Pacific Oceans. Donkeys evolved in the Old World and were confined there until the Columbian Exchange was underway. This chapter explores the introduction of the donkey and the mule to the Americas and, more briefly, to southern Africa and Australia. In keeping with my emphasis on seeking archaeological evidence with which to illuminate the donkey’s story, I omit other aspects of its expansion, such as the trade in animals to French plantations on the Indian Ocean islands of Réunion and Mauritius or, on a much greater scale, India to meet the demands of the British Raj. These examples nevertheless reinforce the argument that mules and donkeys were instrumental in creating and maintaining the structures of economic and political power that Europeans and Euro- Americans wielded in many parts of the globe. From Brazil to the United States, Mexico to Bolivia, Australia to South Africa, they helped directly in processing precious metals and were pivotal in moving gold and silver from mines to centres of consumption. At the same time, they aided the colonization of vast new interiors devoid of navigable rivers, maintained communications over terrain too rugged for wheeled vehicles to pose serious competition, and powered new forms of farming. Their contributions to agriculture and transport were well received by many of the societies that Europeans conquered and their mestizo descendants. However, they also provided opportunities for other Native communities to maintain a degree of independence and identity at and beyond the margins of the European-dominated world.

Full textAbstract:
The purpose of this paper is to evaluate the diagnosis of urban solid waste (USW) in the State of Mexico, through the framework of sustainability. Urban areas represent a focus of attention for local administrations since they represent spaces of economic importance in the Gross Domestic Product. At the same time, these areas favor the concentration of population and air, water and soil pollution in these areas. The analysis included documentary review and diagnosis of urban solid waste (USW) in the State of Mexico, for which it is necessary to investigate different aspects of utmost importance, as well as some background information that involves not only the state, since in order to compare it is necessary to know the management of USW in Mexico at a national level first and then focus on the State of Mexico. As we know, MSW has increased over time due to the demographic and industrial growth of the country, the change in consumption habits of the population, the increase in welfare levels, and the tendency to abandon rural areas to concentrate in urban centers. This has substantially modified the quantity and composition of MSW.

Ukraine has felt the impact of strong force, which has affected the level of happiness in the country. The circumstances were military actions which was provoked by the aggression of the Russian Federation. A whole generation of people knew about the war only from historical sources and had no previous experience of survival. During the war, basic physiological needs became a priority for the civilian population of Ukraine: security, water, food, heat, sleep, medicine. All other needs of a higher order have ceased, or become to be inconsiderable. The war did not make people happy, but it changed their behavior, which was due to the need to make important current and future decisions. Current decisions focused on survival, while long-term decisions focused on choosing one of the alternative life options, taking into account its expected quality and subjective prediction of personal happiness and happiness of their children. All this has led to a number of transformations in the socio-economic sphere, such as: falling incomes and rising household expenditures; change in the structure of consumption; shortage of certain foods and medicines; the impact of inflation; intensification of migration processes; demographic disparities and family separation; reduction of human resources; reduction of life expectancy and deterioration of health of Ukrainians; limited transport and logistics within the country; termination of a significant part of enterprises and small businesses; heavy load on social infrastructure facilities; increasing the number of individuals and families in difficult life circumstances, etc. According to the Phoenix Effect, life is expected to recover very quickly after the war.

Full textAbstract:
The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the industrial and urban consumers, there is a perennial shortage of power in the agriculture sector. Consequently, there is an emergent need to produce more power in order to fulfil the needs of this sector effectively. One way of accomplishing this is setting up captive, preferably rural based, small power generation plants. In these power plants, instead of water-head, diesel oil or coal, we can use agri-residue to produce electricity. One such power plant (1–2 MW capacity) can satisfy the power need of 25 to 40 nearby villages. The agriwaste like rice straw, sugarcane-trash, coir-pith, peanut shells, wheat stalks & straw, cottonseed, stalks and husk, soyabean stalks, maize stalks & cobs, sorghum. Bagasse, wallnut shells, sunflower seeds, shells, hulls and kernels and coconut husk, wastewood and saw dust can be fruitfully utilized in power generation. This stuff is otherwise a waste and liability and consumes a lot of effort on its disposal; in addition to being a fire and health hazard. Agriwaste stuff which at present is available in abundance and prospects of its utilization in producing energy are enormous. This material can be procured at reasonably low rates from the farmers who will thus be benefited economically, apart from being relieved of the responsibility of its disposal. Agri-residue has traditionally been a major source of heat energy in rural areas in India. It is a valuable fuel even in the sub-urban areas. Inspite of rapid increase in the supply of, access lo and use of fossil fuels, agri-residue is likely to continue to play an important role, in the foreseeable future. Therefore, developing and promoting techno-economically-viable technologies to utilize agri-residue efficiently should be a persuit of high priority. Though there is no authentic data available with regard to the exact quantity of agricultural and agro-industrial residues, its rough estimate has been put at about 350 mt per annum. It is also estimated that the total cattle refuse generated is nearly 250 mt per year. Further, nearly 20% of the total land is under forest cover, which produces approximately 50 mt of fuel wood and with associated forest waste of about 5 mt.(1). Taking into account the utilization of even a portion (say 30%) of this agri-residue & agro-industrial waste as well as energy plantation on one million hectare (mha) of wastelands for power generation through bioenergy technologies, a potential of some 18000 MW of power has been estimated. From the foregoing, it is clear that there is an enormous untapped potential for energy generation from agri-residue. What is required is an immediate and urgent intensification of dedicated efforts in this field, with a view to bringing down the unit energy cost and improving efficiency and reliability of agri-waste production, conversion and utilisation, leading to subsequent saving of fossil fuels for other pressing applications. The new initiatives in national energy policy are most urgently needed to accelerate the social and economic development of the rural areas. It demands a substantial increase in production and consumption of energy for productive purposes. Such initiatives are vital for promoting the goals of sustainability. cleaner production and reduction of long-term risks of environmental pollution and consequent adverse climatic changes in future. A much needed significant social, economic and industrial development has yet to take place in large parts of rural India; be it North, West, East or South. It can be well appreciated that a conscious management of agri-residue, which is otherwise a serious liability of the farmer, through its economic conversion into electric power can offer a reasonably viable solution to our developmental needs. This vision will have to be converted into a reality within a decade or so through dedicated and planned R&D work in this area. There is a shimmering promise that the whole process of harvesting, collection, transport and economic processing and utilisation of agri-waste can be made technically and economically more viable in future. Thus, the foregoing paras amply highlight the value of agri-residue as a prospective source of electric power, particularly for supplementing the main grid during the lean supply periods or peak load hours and also for serving the remote areas in the form of stand-alone units giving a boost to decentralised power supply. This approach and option seems to be positive in view of its potential contribution to our economic and social development. No doubt, this initiative needs to be backed and perused rigorously for removing regional imbalances as well as strengthening National economy. This paper reviews the current situation with regards to generation of agriwaste and its prospects of economic conversion into electrical power, technologies presently available for this purpose, and the problems faced in such efforts. It emphasizes the need for an integrated approach to devise ways and means for generating electrical power from agriwaste; keeping in mind the requirements of cleaner production and environmental protection so that the initiative leads to a total solution.

Full textAbstract:
Selecting the appropriate level of filtration for a gas turbine helps to minimize overall unit costs and maximize net revenue. When selecting a filter type and configuration, one must consider the initial costs, operational costs, and ongoing maintenance costs for both the filter and corresponding impacts on unit performance. Calculations are complex, and a fully functional framework is needed to properly account for all aspects of the life cycle and provide an opportunity to optimize filter selection and water wash scenarios for specific plant operating conditions. Decisions can generally be based on several different criteria. For instance, one may wish to minimize maintenance costs, maximize revenue, minimize fuel consumption, etc. For criteria that can be expressed in monetary terms, Life Cycle Cost Analysis (LCCA) is a means to simultaneously consider all criteria and reduce them to a single parameter for optimization using present value arithmetic. To be practically applied, the analysis must include all the significant inputs that would have an impact on the relative comparison between alternatives, while excluding minor inputs that would unduly add to complexity. This paper provides an integrated, quantitative, and transparent approach to life cycle cost analysis for gas turbine inlet filtration. Most prior art tends to focus either on how to perform the life cycle cost analysis (with simplified assumptions on the impact of filtration on performance), or on a specific technical aspect of filtration such as filter efficiency and performance, the impact of dust on compressor blading and fouling, or the impact of fouling on overall gas turbine performance. Many of these studies provide useful insight into specific aspects of gas turbine degradation due to fouling, but make simplifying assumptions that can lead to inaccuracies in application. By heavily leveraging prior work, this paper provides the reader with an overview of all aspects of the functionality required to perform such a life cycle analysis for gas turbine filtration. This work also serves as a technical summary of the underlying physics models that lead to the development of EPRI’s Air Filter Life-Cycle Optimizer (AFLCO) software. The software tool provides a method to account for the influence of gas turbine type, operating conditions, load profile, filtration choices, and wash type and frequency on overall life-cycle costs. The AFLCO tool is focused on guiding the user to make optimum filter selections and water wash scheduling, accounting for all the significant parameters that affect the economic outcome. Revenue and cost quantities are considered simultaneously to determine the net present value of gross revenue minus filtration and water wash costs over a multiple year analysis period. The user defines the scenarios and the software displays the net present value (NPV) and present value difference between the scenarios. The preferred configuration from an LCCA perspective is that which yields the highest present value for net revenue. The user can iterate on multiple scenarios to seek further increases in NPV. The paper provides relevant example case studies to illustrate how LCCA evaluations of inlet air filters and water wash frequency can be applied to optimize gas turbine economic performance. The intent of the paper is to provide the user with a summary of prior work that can be integrated to provide a more holistic, complete life cycle cost analysis and describes the framework used within the AFLCO software. The underlying technical analysis in this paper can be applied to any life cycle cost analysis.

Abstract Polygeneration improves energy efficiency and reduces both energy consumption and pollutant emissions compared to conventional generation technologies. A polygeneration system is a variation of a cogeneration system, in which more than two outputs, i.e., heat, power, cooling, water, energy or fuels, are accounted for. In particular, polygeneration systems integrating solar energy and water desalination represent promising technologies for energy production and water supply. They are therefore interesting options for coastal regions with a high solar potential, such as those located in southern Peru and northern Chile. Notice that most of the Peruvian and Chilean mining industry operations intensive in electricity and water consumption are located in these particular regions. Accordingly, this work focus on the design and integration of a polygeneration system producing industrial heating, cooling, electrical power and water for an industrial plant. In particular, the design procedure followed in this work involves integer linear programming modeling (MILP). The technical and economic feasibility of integrating renewable energy technologies, thermal energy storage, power and thermal exchange, absorption chillers, cogeneration heat engines and desalination technologies is particularly assessed. The polygeneration system integration carried out seeks to minimize the system total annual cost subject to CO2 emissions restrictions. Particular economic aspects accounted for include investment, maintenance and operating costs.

Abstract In order for a sustainable product to be successful in the market, designers must create products that are not only sustainable in reality, but are also sustainable as perceived by the customer — and reality vs. perception of sustainability can be quite different. This paper details a design method to identify perceived sustainable features (PerSFs) by collecting online reviews, manually annotating them using crowd-sourced work, and processing the annotated review fragments with a Natural Language machine learning algorithm. We analyze all three pillars of sustainability — social, environmental, and economic — for positive and negative perceptions of product features of a French press coffee carafe. For social aspects, the results show that positive PerSFs are associated with intangible features, such as giving the product as a gift, while negative PerSFs are associated with tangible features perceived as unsafe, like sharp corners. For environmental aspects, positive PerSFs are associated with reliable materials like metal while negative PerSFs are associated with the use of plastic. For economic aspects, PerSFs mainly serve as a price constraint for designers to satisfy other customer perceptions. We also show that some crucial sustainability concerns related to environmental aspects, like energy and water consumption, did not have a significant impact on customer sentiment, thus demonstrating the anticipated gap in sustainability perceptions and the realities of sustainable design, as noted in previous literature. From these results, online reviews can enable designers to extract PerSFs for further design study and to create products that resonate with customers’ sustainable values.

Full textAbstract:
Abstract Gas developments are required to facilitate energy transition from carbon intensive energy to a sustainable balance of green and blue energy. The next decade will focus on exploiting gas fields globally to support this. A significant number of these fields are located in deepwater and /or are long distances from existing gas processing / LNG plants. Transporting large volumes of gas from remote gas fields over longer distances and in deeper waters remains technologically and economically challenging. Conventional and near-term development options include subsea compression, floating vessels with topside compression and pipeline tie-back to shore, or floating liquefied natural gas vessels. This paper and study are supported by The Oil & Gas Technology Centre (OGTC) and UK Oil and Gas Authority. It examines development options for a 200 km long 1700 m water depth tie back using integrated production modeling linked to power demands, along with installed steel tonnages. The Scope 1 and 2 emissions per unit of gas produced are analysed via a life cycle assessment using ISO 14044 as guidance for a long-distance gas tieback to the point of sale (inclusive of processing to sales specification). The major power intensive equipment used to develop these fields will be presented showing their proportion of the power consumption compared with the total; these include compression either onshore, offshore or subsea as well as the efficiency of the power generation devices in these environments. The paper will highlight the economics of each option and how varying the carbon price changes the commercial position of each option. The paper will show that by understanding what drives emissions, and how emissions relate to the amount of gas produced, that concept selection can drive upwards of 50% reduction in life cycle carbon emissions whilst improving project economic performance. This paper examines multiple innovative technologies, providing technology readiness of new concepts based on the benchmarked study focusing both economic and carbon emission aspects. Finally, the paper will show that better economic outcomes with the decarbonisation of gas gathering systems is technically possible and can be deployed subsea to help meet the energy transition and allow the development of remote and deeper gas fields.

Full textAbstract:
In the last decade, the service sector had a very rapid growth, due to the so-called “tertiarisation” of the economy. Accordingly, the energy consumption, mainly attributable to public and private buildings, is rapidly growing, thus making buildings energy saving one of the main issues of the energy policy at regional, national and international levels. To this aim, we developed an effective methodology to improve energy efficiency of the service sector buildings. This may represent a handy great opportunity to save natural and economic resources, especially where the buildings structure and the technical systems are old, the maintenance activities are not carefully carried out or a systematic energy management is not applied. Nevertheless, actions in this direction are often considered too expensive and complicated, if compared with residential energy optimization, because of the big extension, the variety of activities and the high number of occupants typical of the service sector buildings. The developed approach for energy audits aims to investigate the energy aspects of existing non-domestic buildings in a structured way, in order to clearly identify their energy saving potential and to improve their energy performances. The main goal of the study is defining a general methodology to analyze the current energy use and consumption considering a limited number of their peculiar elements such as dimensions, activities, users behavior, technical systems data and energy bills. Furthermore, these informations are completed by an appropriate energy measuring campaign. All the possible energy uses in service buildings are taken into account (i.e. lighting, ventilation, air conditioning, hot water production). The results obtained from the analysis allow to evaluate a global level of building energy efficiency, and to identify those single areas, specific systems or everyday activities where energy is wasted. These considerations also provide basis for programming cost-effective energy saving action plans. The effectiveness of the proposed methodology is demonstrated through a case study for an Administrative Center building in Rome, Italy. Results demonstrate the methodology reliability and the cost reduction potentialities.

Full textAbstract:
Abstract Artificial Intelligence (AI) has significant potential to optimize practices, processes, and energy consumption along with maximizing yield, quality, and uptime. This has substantial impact on putting organizations on the path to net-zero, as such optimizations can reduce greenhouse gas emissions by 20% with minimal capital investments. This comprehensive study presents proven industrial case studies that delivered economically strong strategies coupled with sustainability practice and providing strategic insights to identify, manage and/or attenuate the associated impacts. Environomics presented in this study is a novel framework which deals with unifying economic strategies with sustainability practices (through artificial intelligence) for optimal business performance in terms of finances but also environmental impact. This is achieved through a track, trace, and optimize approach for resources (particularly emissions, energy, water, waste, materials,, and safety) This was achieved through a combination of AI methods such as unsupervised machine learning, multi-variate optimization, and the implementation of similarity measures. A few of the inputs included well data (including production data, drilling data, completion data etc.), logistics/supply chain data (scheduling data, production inventory, mobilization data etc.), safety data (near-miss, observations, hazards, disciplines and insights etc.) with associated costs and emission data. Multiple industrial case studies are presented where sustainability metrics are identified through validated AI models to optimize productivity while reducing emissions and inventory. For instance, well profiling can be used to identify historical parameters that have maximized production potential while optimizing for aspects such as cost or emissions. Furthermore, we can identify the optimal completion parameters for a new well which satisfies carbon targets, use well profiles to build an optimized drilling schedule that meets budget or production criteria while still achieving production targets and optimizing drilling rig routes. Thus, the approach can quickly (within run time) solve interrelated environomic challenges in the reservoir studies space and the field development space. Further case studies indicate that the supply chain can have immense optimization impact on scope 3 aspects with results indicating 30-50% asset utilization improvement with respect to fleets (Vessel, Truck, Rigs). With respect to materials, a 10-20% reduction of material inventory levels all improved through AI. As the workforce are also part of the environment it has been observed that identifying unsafe behaviors within a large operation, also leads to enhanced sustainability behaviors. The models indicate potential of overall emission reduction ranging from 12-20%. This led to the comprehensive framework presented in this study to support sustainable practices that are also economically feasible and deployable. The real-time sustainability metrics generated has immense values in terms of decision-making processes and scenario generation in a fraction of the time that is required using traditional approaches. In addition to assessing the scope of impact, a novel multidisciplinary study and framework is presented to analyze environomic strategies to propose a market-oriented approach through the application of artificial intelligence. Furthermore, industrial, and academic case studies have been evaluated to identify, predict, and optimize the crucial parameters within such workflows that are effective in reducing resources utilized and associated emissions.

"Energy Sustainability Study of a Rural ICT Telecenter at the Bario Highland." In ASME 2007 Energy Sustainability Conference. ASMEDC, 2007. http://dx.doi.org/10.1115/es2007-36061.
Full textAbstract:
The eBario project has won the eAsia Award and the Mondialogo Engineering Award in 2004 and 2005 respectively for it’s successful implementation of an Information and Telecommunications Technology Center (ICT) and solar renewable energy-incentive rural community project at the Bario Highland of Sarawak, East Malaysia, Borneo (http://www.unimas.my/ebario/). Although solar photovoltaic (PV) energy has been opted for power generation at the ICT Telecenter for the past five years, there is still a need to investigate the cost-effectiveness of the current energy setup as well as to conduct sustainability study taking into account factors such as system efficiency, weather, costs of fuel, operating costs, as well as to explore the feasibility of implementing alternative energy resources for the rural ICT Telecenter. Recent theoretical study conducted has shown that renewable combined power systems are more sustainable in terms of supplying electricity to the ICT Telecenter, and in a more cost-effective way compared to a standalone PV system which is subject to the cloud and the recent dense haze problems. For that purpose, two combined power systems are being put into consideration namely PV-Hydro and PV-Hydro-Fuel Cell, where the total simulated annualized cost for these two system configurations are US$10,847 and US$76,010 respectively as far as the present location is concerned. The PVHydro-Fuel Cell produces electrical energy at the amount of 3,577 kWh/yr while the annual energy consumption is 3,203 kWhr/yr. On the other hand, PV-Hydro produces 3,789 kWhr/yr of electricity annually load which consumes energy at 3,209 kWhr/yr. Results thus obtained has shown that the PVHydro scheme is expected to have advantages over the existing PV standalone system. Firstly, it is more cost-effective. Secondly, it provides the best outcomes for the local indigenous community and the natural highland environments both for now and the future. Thirdly, it also able to relate the continuity of both economic and social aspects of the local society as a whole. As the combined PV-Hydro system had been chosen, plus for completeness purposes, the present paper also discussed the custom design and construction of a small waterwheel breast-shot hydro-generator, suited to the local location and existing water energy resources. Energy saving design calculations and Sankey diagram showing the energy flows for the new combined system are also given herein. Finally, the energy system performance equations and the performance curves introduced in this study provide a new simple method of evaluating renewable energy systems.
