Full textAbstract:
Coal mine drainage waters are low in pH with varying amounts of iron and manganese and are generally brackish. The Austar Coal Mine in NSW, Australia, sought alternatives to their current lime dosing as the pre-treatment before the downstream reverse osmosis plant. Undesirable operating aspects of the current system include manganese and gypsum scaling/fouling, the need for anti-scalants and reduced water recovery. Thirteen processes for acid mine drainage were initially considered. The preferred process of caustic and ozone for Mn(II) oxidation was pilot tested at up to 0.74 kL/hr at the mine site. Under proper conditions and no aeration, about 81 per cent of the Fe could be removed (initially at 156 mg/L) as green rust. Supplemental aeration followed first-order kinetics and allowed 99.9 per cent Fe(II) oxidation and removal but only with a hydraulic residence time of about 47 minutes. The addition of supplemental Cu catalyst improved Fe removal. Ozone applied after caustic was effective in stoichiometrically oxidising recalcitrant Mn(II) and any remaining Fe(II). Control of the ozonation was achieved using the oxidation reduction potential during oxidation of the Mn(II) species. The use of caustic, followed by ozone, proved economically comparable to the current lime pre-treatment.

Full textAbstract:
This paper reviews the interactions between water and nitrogen from physiological, agronomic, economic, breeding and modelling perspectives. Our primary focus is wheat; we consider forage crops, sorghum and legumes where relevant aspects of water–nitrogen interactions have been advanced. From a physiological perspective, we ask: How does nitrogen deficit influence the water economy of the crop? How does water deficit influence the nitrogen economy of the crop? How do combined water and nitrogen deficit affect crop growth and yield? We emphasise synergies, and the nitrogen-driven trade-off between the efficiency in the use of water and nitrogen. The concept of nitrogen–water co-limitation is discussed briefly. From agronomic and economic perspectives, the need to match supply of nitrogen and water is recognised, but this remains a challenge in dryland systems with uncertain rainfall. Under-fertilisation commonly causes gaps between actual and water-limited potential yield. We discuss risk aversion and the role of seasonal rainfall forecasts to manage risk. From a breeding perspective, we ask how selection for yield has changed crop traits relating to water and nitrogen. Changes in nitrogen traits are more common and profound than changes in water-related traits. Comparison of shifts in the wheat phenotype in Australia, UK, Argentina and Italy suggests that improving yield per unit nitrogen uptake is straightforward; it requires selection for yield and allowing grain protein concentration to drift unchecked. A more interesting proposition is to increase nitrogen uptake to match yield gains and conserve protein in grain. Increased stomatal conductance is a conspicuous response to selection for yield which partially conflicts with the perception that reduced conductance at high vapour pressure deficit is required to increase water- use efficiency; but high stomatal conductance at high vapour pressure deficit may be adaptive for thermal stress. From a modelling perspective, water and nitrogen are linked in multiple ways. In crops where water limits growth, reduced biomass reduces nitrogen demand. Reciprocally, nitrogen limitation during crop expansion reduces leaf area index and increases the soil evaporation : transpiration ratio. Water–nitrogen interactions are also captured in the water-driven uptake of nitrogen by mass flow and diffusion and in the water-driven processes of nitrogen in soil (e.g. mineralisation). The paper concludes with suggestions for future research on water-nitrogen interactions.

Full textAbstract:
Growing population, depleting fossil fuels, economic expansions, and energy intensive life style demand are resulting in higher energy prices. We use energy as of heat and electricity, which can directly be obtained from sun using thermal collectors and solar cells. Solar thermal systems are gaining attention for water and space heating applications due to green aspects of solar energy. A solar thermal collector is a vital part of solar thermal energy system to absorb radiant energy from the sun. In this study, a solar water heating (SWH) system has been designed and simulated in the TRNSYS ® software using thermal and chemical properties of heat transfer fluids using REFPROP for dwellings located on ±31° latitudes (+31 Lahore in Pakistan and -31° Perth in Australia). We present an efficiency parametric optimization-based model for water and space heating. Simulation results for four types of solar thermal collectors are presented, and performance is analyzed on the basis of output temperature ( T out ), solar fraction ( f ), and collector efficiency ( η ). This study evaluates the comparative performance of evacuated tube collector (ETC), flat-plate collector (FPC), compound parabolic concentrator (CPC), and thermosiphon-driven systems. Our findings conclude the evacuated glass tube collector achieves the highest solar fraction, i.e., 50% of demand coverage during August in Pakistan and February in Australia, with an overall average of 43% annually.

Full textAbstract:
Water sensitive urban design (WSUD), as a typical green stormwater infrastructure (GSI), contains various facilities to decrease the urbanization impacts and enhance the values of amenity, ecosystem, and livability in Australia. Although WSUD has developed over 30 years, existing studies for WSUD performances have sometimes ignored its economic and social benefits, and there is still a lack of an integrated framework to optimize the GSI combinations based on various criteria in a site. This paper aims to utilize “score-rank-select” strategy to comprehensively assess WSUD combination scenarios from functional, economic, social, and environmental aspects, by taking the University of Melbourne (Parkville campus) as a case study. In detail, multi-criteria decision analysis (MCDA) was used for weight determination and scenario comparison. The results showed that scenario 4 with 52% green WSUD facilities had the highest assessment score (0.771) among the five scenarios, while the final score (0.758) of scenario 5 was lower than scenario 4 although its green facility proportion reached 69%. The trade-off relation between the proportion of grey and green WSUD facilities was further demonstrated. Additionally, this paper strongly recommends that the MCDA-based comprehensive assessment framework described here can be generally promoted for the water sector to solve the decision-making problems. The use of such a framework can further promote sustainable development by helping water managers to make informed and inclusive decisions involving a variety of factors.

Full textAbstract:
Planning for a low-carbon future in Australia will need to address simultaneously three aspects of sustainable development: centralisation/regional development, mobility and communication. After reviewing existing roadmaps for low-carbon growth by 2050, the article identifies the importance for Australia of an integrated and mutually reinforcing set of measures, based on a bold approach to urban and regional planning. Taking account of national geography, the approach is based on the decentralisation of energy production, use and storage, and on new uses of communication, transport and the location of food, water and mineral resources. Revitalised regional centres could be connected, through new energy and transport solutions, by a national transport arc and electrified highways. The use of infrastructure funding to support low-carbon regional development would avoid the ‘tragedy of the commons’, transcending incremental, cumulative approaches based on compensation and incentives for household, business and sectoral abatement efforts. It would generate long-term environmentally sustainable development.

Full textAbstract:
Access to water is a critical aspect of livestock production, although the relationship between livestock weight gain and water quality remains poorly understood. Previous work has shown that water quality of poorly managed farm dams can be improved by fencing and constructing hardened watering points to limit stock access to the dam, and revegetation to filter contaminant inflow. Here we use cattle weight gain data from three North American studies to develop a cost-benefit analysis for the renovation of farm dams to improve water quality and, in turn, promote cattle weight gain on farms in south-eastern Australia. Our analysis indicated a strong likelihood of positive results and suggested there may be substantial net economic benefit from renovating dams in poor condition to improve water quality. The average per-farm Benefit-Cost Ratios based on deterministic assumptions was 1.5 for New South Wales (NSW) and 3.0 for Victoria in areas where rainfall exceeds 600mm annually. Our analyses suggested that cattle on farms in NSW and Victoria would need to experience additional weight gain from switching to clean water of at least 6.5% and 1.8% per annum respectively, to break even in present value terms. Monte Carlo simulation based on conservative assumptions indicated that the probability of per-farm benefits exceeding costs was greater than 70%. We recommend localised experiments to assess the impact of improved water quality on livestock weight gain in Australian conditions to confirm these expectations empirically.

Full textAbstract:
Droughts can cause significant damage to agriculture and water resources leading to severe economic losses. One of the most important aspects of drought management is to develop useful tools to forecast drought events, which could be helpful in mitigation strategies. The recent global trends in drought events reveal that climate change would be a dominant factor in influencing such events. The present study aims to understand this effect for the New South Wales (NSW) region of Australia, which has suffered from several droughts in recent decades. The understanding of the drought is usually carried out using a drought index, therefore the Standard Precipitation Evaporation Index (SPEI) was chosen as it uses both rainfall and temperature parameters in its calculation and has proven to better reflect drought. The drought index was calculated at various time scales (1, 3, 6, and 12 months) using a Climate Research Unit (CRU) dataset. The study focused on predicting the temporal aspect of the drought index using 13 different variables, of which eight were climatic drivers and sea surface temperature indices, and the remainder were various meteorological variables. The models used for forecasting were an artificial neural network (ANN) and support vector regression (SVR). The model was trained from 1901–2010 and tested for nine years (2011–2018), using three different performance metric scores (coefficient of determination (R2), root mean square error (RMSE), and mean absolute error (MAE). The results indicate that ANN was better than SVR in predicting temporal drought trends, with the highest R2 value of 0.86 for the former compared to 0.75 for the latter. The study also reveals that sea surface temperatures and the climatic index (Pacific Decadal Oscillation) do not have a significant effect on the temporal drought aspect. The present work can be considered as a first step, wherein we only study the temporal trends, towards the use of climatological variables and drought incidences for the NSW region.

Full textAbstract:
Soil security identifies global challenges and a series of dimensions that are necessary requirements to meet those global challenges using sustainable land management. The soil security concept is applied to two contrasting soil landscape systems with varying climate, landform and soil types. Previous methodologies for assessing land and soil capability are combined within the soil security conceptual approach. The land and soil capability methodologies are used to assess how the soil condition changes in response to the stresses and forcing associated with land management and land and soil degradation processes. It is the soil capability that defines how the soil condition changes between the reference state of the soil condition, or the genoform, and the soil condition under land use, or the phenoform. The conclusion is that soil capability, which is one of the dimensions used to apply the soil security concept, is a complex dimension and has several aspects or further facets to be considered to achieve sustainable land management. It is apparent that in assessing soil capability, the following facets are relevant. I: The capacity of the soil to provide ecosystem services to meet the global challenges outlined for Soil Security. II: The stability of the soil condition to land degradation processes resulting from the effects of land management practices and the environmental stresses on the soil. III: The capacity to recover following degradation. Facets II and III can be considered the resilience. An important conclusion is that the soil capability cannot be assessed without taking into account features of the landscape including climate and landform. Two examples from south eastern Australia of the application of these facets of soil capability to on-ground situations are presented. The Cowra Trough Red Soils in the Australian wheat belt are a set of soils, primarily contributing to meeting the global challenge of food security. The major degradation processes threatening the stability of these soils are water erosion and soil acidification. The Kosciusko National Park in the Snowy Mountains region is primarily contributing to meeting the challenges of water security for the irrigation industry in the Murray Darling Basins and energy security through the production of hydroelectricity. The set of soil landscapes also contributes to biodiversity protection and human health and well-being. The major degradation processes threatening the stability of these soils and their capacity to meet the global challenges are water and wind erosion. A major limitation is the poor capacity of these soils to recover once degraded. Identifying the main ecosystem services provided by the two examples, together with the major risks of land degradation can clarify extension, economic and policy aspects of sustainable land management for the two sets of soil landscapes. For the Cowra Trough Red Soils, management of water erosion and soil acidification are essential for maintaining the contribution of the area to food security. For the Kosciusko National Park, the control of water and wind erosion are essential to maintain the contribution of the area to water and energy security.

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.

The aim of the study was to characterize the main trends in the development of citizen science (CS), which has been attracting growing interest from society since the beginning of the 21st century, which is associated with the development of digital technologies, and the ability to connect to the Internet. According to the Oxford Dictionary, “Citizenship Science is the collection and analysis of data related to the natural world by members of the general public, usually as part of a collaborative project with professional scientists “. This movement has had significant activity in the countries of Western Europe, the USA, Australia, and in the last decade in China. An analysis of completed projects shows that citizen science has the greatest impact on research in the field of biology, ecology, and solutions to environmental problems and is mainly used for collecting and classifying data. The accuracy of the data obtained by CS representatives depends on the proper organization of research and requires constant monitoring and cooperation with professional scientists. Citizens’ motivation to participate in research can also influence the results of CS projects. Three general aspects are highlighted as motivation for participation in CS: a) raising the individual scientific and educational level and the desire to increase public awareness; b) filling gaps in government monitoring and identifying local problems; c) harnessing scientific knowledge to inform policymakers and decision-makers and ensuring consistency of actions at different scales. An important area of research in citizen science is monitoring the quality of water in water bodies, as evidenced by more than 800 works published during 2010-2020. In periodicals indexed by the Web of Science. It is relevant to involve representatives of citizen science in solving the tasks facing SDG 6 “Clean water and adequate sanitation”, one of the 17 global goals that were adopted at the UN Summit on Sustainable Development (2015) for the period 2015-2030. The participation of citizen science can be significant in the context of SDG 6.3.2 “Identifying the proportion of water bodies with good water quality”, as these studies relate to the monitoring of water bodies at the community level. The FreshWater Watch program, launched in 2012, is based on the continuous monitoring of freshwater bodies. The program has both a global and a local level. Global level – citizen scientists in different countries participating in the program work according to the same methods and register a common set of parameters that are loaded into the same database. Local level – working with local groups and scientists who have scientific questions about their specific water bodies. Thus, using global approaches, it is possible to answer local questions about water quality and the state of ecosystems. In Ukraine, the situation with citizen science is fundamentally different from that described above. There is no citizen science in the same form as in the countries of Western Europe, North America, Australia, and East Asia in Ukraine. This is connected both with the general economic situation of the country and, accordingly, the constant reduction of scientific institutions, a decrease in the interest of citizens in science and with moral and ethical aspects (from the skepticism of professional Ukrainian scientists regarding the activities of representatives of citizen science to the unwillingness of broad strata of citizens to spend their time on work in CS projects). But on Facebook (FB) there are groups of biological, hydrological, and geological orientations in Ukraine, which have their own sites in FB and carry out certain work. Ukraine’s integration into the structure of the European Union will contribute to the emergence of new opportunities for further development of civil society, including participation in citizen science projects.

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.

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 Methodical approaches to calculating the economic efficiency of natural resources use are considered. The characteristics of water services regulation in Ukraine are given. Economic indicators of regional development in the Vistula River basin are investigated. The dynamic analysis of revenues for special water use and expenditures for water resources in the Vistula River basin is carried out. Revenues to the state and local budgets were investigated in terms of rent payments, environmental tax, rent and special use of fish and other aquatic bioresources. To calculate the economic efficiency, the state expenditures under the budget program “Operation of the state water management complex and water resources management” in the Vistula River basin area were used. The obtained indicator was improved by taking into account the environmental component. Expenditures in the context of capital and current investments from the state and local budgets for environmental programs in the field of water resources protection were analyzed. The indicator of reduced costs for water resources in 2020 is formed. It is proposed to assess economic efficiency through the indicator of the level of coverage of the reduced costs of water resources.

Australia is experiencing the most dramatic and comprehensive reform of its water industry, placing it at the leading edge of water management internationally. A key feature of the reforms is the explicit linking of economic and environmental objectives: in that the reforms seek to improve environmental management of the nation’s river systems by increasing efficiency of water use via water markets. However, there is growing evidence to evince that water markets are failing to achieve environmental objectives. This paper uses the insights of economic sociology to analyse this failure, and argues that economic efficiency does not and will not guarantee environmental effectiveness because newly constructed water markets are embedded in existing social processes/industry structures and are permeated by existing power relations. For real environmental benefits to accrue, existing water markets must be seriously restructured. This paper explores the elements of such a restructure and suggests that it is unlikely to succeed without strong state action and coordinated policymaking, institutional reform, adjustment packages, significant community involvement, and the participation of the rural sector. Finally, it proposes that social capital could play a pivotal role in the restructuring of the Australian water industry.

Sugarloaf Reservoir, one of Melbourne's newer storages, draws an increasing proportion of its water from the unprotected and polluted lower Yarra requiring all supply to be comprehensively treated before being supplied to consumers. Because of this special situation, compared to harvesting from protected catchments, a recreational use study of the reservoir and its small natural catchment was initiated. The first phase of this study was undertaken by Dr J Forsyth of the Microbiological Diagnostic Unit, University of Melbourne which recommended that, from the public health point of view, the present nominal recreational use (passive) at Sugarloaf Reservoir could be extended to include shore based fishing, establishment of a catchment nature trail, sailing, rowing, youth club and model yacht sailing. A Phase 2 study reported on the financial, managerial aspects, etc, not addressed by Dr Forsyth, while the “implementation stage” is being currently considered in a third phase. A report on this last phase is to be submitted to the Board and Minister for Water Resources for consideration for the summer of 1988.

Full textAbstract:
This paper describes recent experience with integrated resource planning (IRP) and the application of least cost planning (LCP) for the evaluation of demand management strategies in urban water. Two Australian case studies, Sydney and Northern New South Wales (NSW) are used in illustration. LCP can determine the most cost effective means of providing water services or alternatively the cheapest forms of water conservation. LCP contrasts to a traditional approach of evaluation which looks only at means of increasing supply. Detailed investigation of water usage, known as end-use analysis, is required for LCP. End-use analysis allows both rigorous demand forecasting, and the development and evaluation of conservation strategies. Strategies include education campaigns, increasing water use efficiency and promoting wastewater reuse or rainwater tanks. The optimal mix of conservation strategies and conventional capacity expansion is identified based on levelised unit cost. IRP uses LCP in the iterative process, evaluating and assessing options, investing in selected options, measuring the results, and then re-evaluating options. Key to this process is the design of cost effective demand management programs. IRP however includes a range of parameters beyond least economic cost in the planning process and program designs, including uncertainty, benefit partitioning and implementation considerations.

Full textAbstract:
The water industry in the state of Victoria, Australia underwent significant structural and pricing reforms in the 1990s. Now, attention is focussed on introducing independent economic regulation, and on the sustainable management of water resources. Experience in Victoria, Australia, provides an interesting opportunity to consider the challenges of reconciling independent economic regulation of profit focused businesses while meeting goals for sustainability in the most efficient way. We conclude that effective integration of sustainability and economic regulation requires consideration of the incentives in economic regulation; investment in defining and collecting data and information to support decisions; greater utilisation of market based instruments; wider and extended use of existing evaluation tools and more explicit linking of these tools to decisions about allocation of resources. However we consider that priority should be given to institutional arrangements; we consider that reform will be required to align arrangements with objectives and thus facilitate efficient and consistent decision-making.

Modernization of the management system of water use of Ukraine depends on an adequate analysis of the real situation, calibration of the influence of factors and risks, and especially a multi-faceted, comprehensive understanding of the interrelationships and interdependence of various components of the economy, ecology, law, economic activity, administration, which are united tangentially to the water sphere.
Only such an approach is capable of forming a vision of the necessary components of an effective water use policy and preparation of viable action algorithms.
In Ukraine, the processes of implementation of international and European standards in the field of ecology, monitoring procedures are ongoing, an agreed national model of water use is being formed, taking into account both ecological and economic principles; constructions of optimal management in the water sphere are being developed. The above aspects focus on achieving a balance between water needs and water conservation and protection.
Key words: water policy, water use sectors, vulnerability, modernization.

Full textAbstract:
Agricultural lands of the Russian Federation are intensively subjected to degradation and desertification as a result of irrational economic activity, which, against the background of unfavorable climatic factors, led to the destruction of natural ecosystems, degradation of the soil cover and ultimately to the creation of the unfavorable ecological environment. About 65 % of 130 million hectares of arable land, are exposed to water and wind erosion. Only by water erosion, 10 % of arable land lost 30–60 % of fertility and almost 25 % lost 10–30 %. As a result of deflation 25million hectares of agricultural land in the European part of the Russian Federation are degraded to varying degrees. The concept of the anti-degradation arrangement proposes to use environmental-economic geoinformational monitoring. Within the framework of this approach, the development of cartographic and mathematical models in three time environments is proposed: pre-agricultural, modern degraded, and certainly improved condition. The ecological and economic analysis makes it possible to synthesize information flows and analyze the most important degradation processes. The most important tool for implementing ther adaptive-landscape anti-degradation arrangement of agricultural landscapes is precision farming, which consists of several subsystems: decision-making, monitoring, agronomic techniques, specialized equipment, etc. Computer technologies and telecommunications allow to speed up and optimize production by combining technology and people, which helps reduce costs. Precision agriculture is impossible without using modern advances in collecting, processing and storage of various, often heterogeneous, agricultural information.

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

Understanding human behavior is a complicated and complex endeavor. Academicians and practitioners need to understand the underlying beliefs and motivations to identify current trends and to effectively develop means of communication and education that encourage change in attitudes and behavior. Sociological research can provide information about how and why people make decisions; this information impacts the research and extension community, helping them formulate programs and present information in a way that increases adoption rates. Life cycle assessment can document how plant production impacts the environment. Production of ornamental plants (greenhouse, container, and field produced flowers trees and shrubs) accounted for 4.4% of the total annual on-farm income and 8.8% of the crop income produced in the United States in 2017, representing a substantial portion of farmgate receipts. Greenhouse and nursery growing operations can use this information to increase production and water application efficiency and decrease input costs. Information related to the environmental impacts of plant production, derived from life cycle assessment, can also inform consumer purchase decisions. Information from water footprint analysis quantifies the relative abundance and availability of water on a regional basis, helping growers understand water dynamics in their operation and informing consumer plant purchases based on water availability and conservation preference. Economics can motivate growers to adopt new practices based on whether they are saving or making money, and consumers modify product selection based on preference for how products are produced. Specialty crop producers, including nursery and greenhouse container operations, rely heavily on high quality water from surface and groundwater resources for crop production; but irrigation return flow from these operations can contribute to impairment of water resources. This review focuses on multiple facets of the socioeconomics of water use, reuse, and irrigation return flow management in nursery and greenhouse operations, focusing on grower and consumer perceptions of water; barriers to adoption of technology and innovations by growers; economic considerations for implementing new technologies; and understanding environmental constraints through life cycle assessment and water footprint analyses. Specialty crop producers can either voluntarily adapt practices gradually to benefit both economic and environmental sustainability or they may eventually be forced to change due to external factors (e.g., regulations). Producers need to have the most current information available to inform their decisions regarding water management.

Full textAbstract:
Pasture cropping is a farming system in which annual crops are sown into established perennial pastures. It may provide environmental benefits such as increased groundcover and reduced deep drainage, while allowing traditional crop production in the Mediterranean-style climate of south-western Australia. In this research, we investigated deep drainage and the temporal patterns of water use by a subtropical perennial grass, annual crops, and a pasture-cropping system over a 4-year period. Both the pasture and pasture-cropped treatments reduced deep drainage significantly, by ~50 mm compared with the crop treatment. Competition between the pasture and crop components altered patterns of average daily water use, the pasture-cropped treatment having the highest water use for July, August and September. Consequently, water-use efficiency for grain production was lower in the pasture-cropped plots. This was offset by pasture production, so that over a full 12-month period, water-use efficiency for biomass production was generally greater for the pasture-cropped plots than for either the pasture or crop monocultures. Pasture cropping may be a viable way of generating sustainable economic returns from both crop and pasture production on sandy soils of south-western Australia.

The article is dedicated to the economic and legal aspects of environmental protection when using artificial water bodies. It was proved that to improve the efficiency of administrative responsibility for environmental crimes, the size of compensations and penalties should exceed the cost of actions of environmental protection. This will encourage the entities using artificial water bodies to provide advantages to the measures of environmental protection when using artificial water bodies formed within the limits of private land lots. It was offered to distinguish the legally valid and illegal damage to the environment. It was determined that the payment of compensation for the damage to the environment on the base of the special permission of the authorities was not considered a civil and legal liability. The payment of such compensation shall be considered a term for the legal use of the artificial water body by the methods that can be the reason for the damage to the environment.

The transport system in Russia and the transport support issues of national security differ completely from the Occident and other developed countries due to geostrategic and natural climatic conditions of our country. The integrated transport system, where in a sufficiently coherent manner used are the roads and railways, domestic water and air ways, pipeline transport, is more developed in the European area of the country. However, there is no assessment of economic feasibility for the integrated transport lines system. Firstly, assessment criteria for the transport support efficiency in favor of environmental security; secondly, mathematical economic models of various transport types integrated use in favor of environmental security; thirdly, economic feasibility methods for transport integrated use in favor of environmental security, that unavoidably leads to unreasonable transport operations using the existing rail and water ways at little distances, and increases their base cost by several times versus the transport by road. High dynamics of transport support for economic, demographic and environmental security within a market economy require the development of approach for the transport integrated use in favor of Russia national security. This article describes some practical recommendations for transport systems control bodies regarding the efficiency improvement of their use in favor of environmental security.

Integration means different things to different people and as a consequence appears to only partially deliver on promised outcomes. For effective integrated water cycle management these outcomes should include improved water use efficiency, less waste, environmental sustainability, and provide secure and reliable supply to meet social and economic needs. The objective of integration is the management and combination of all these outcomes as part of a whole, so as to provide better outcomes than would be expected by managing the parts independently. Integration is also a consequence of the Water Reforms embarked on by the NSW State Government in 1995. The key goals of the reforms are clean and healthy rivers and groundwaters, and the establishment of more secure water entitlements for users. They are also essential for meeting the Council of Australian Government (COAG) water management strategies. The policies and guidelines that formed the NSW Water Reforms were the basis of the Water Management Act 2000 (NSW) (WMA) which is the legislative framework for water management in NSW. The NSW Department of Land and Water Conservation has developed an approach to integrated water cycle management for rural centres in NSW based on a catchment and policy context. This approach includes consideration of catchment wide needs and issues, environmental sustainability, government policy and community objectives in the development of an integrated water cycle plan. The approach provides for a transparent assessment of priorities and how to deal with them, and while specific to urban centres, could easily be expanded for use in the management of the whole of the catchment water cycle. Integration of the water cycle is expected to offer benefits to the local environment, community and economy. For instance, any unused proportion of an urban centre's water entitlement, or an offset against this entitlement created through returned flows (such as via good quality sewage effluent discharge to a river), can provide a surplus which is available to be traded on an annual basis. Further, improved demand management within an urban centre can be expected to result in a reduction in abstraction against the licence entitlement. This may result in the increased availability of in-stream water for environmental or other purposes and is expected to increase the economic value of returned water. Improved water use efficiencies are also expected to result in reduced capital works (and their associated costs) as the efficiency of service delivery and resource use improves. In this paper an example of the application of this process is provided and the outcomes discussed.

Full textAbstract:
Rainwater harvesting (RWH) systems can be used to produce drinking water in rural communities, particularly in developing countries that lack a clean drinking water supply. Most previous research has focused on the application of RWH systems for individual urban households. This paper develops a yield-after-spillage water balance model (WBM) which can calculate the reliability, annual drinking water production (ADWP) and benefit–cost ratio (BCR) of a community-scale RWH system for rural drinking water supply. We consider multiple scenarios regarding community aspects, including 150–1000 users, 70–4800 kL rainwater storage, 20–50 L/capita/day (LCD) drinking water usage levels, local rainfall regimes and economic parameters of Australia (developed country) and Vietnam (developing country). The WBM analysis shows a strong correlation between water demand and water supply with 90% system reliability, which allows both Australian and Vietnamese systems to achieve the similar capability of ADWP and economic values of the produced drinking water. However, the cost of the Vietnamese system is higher due to the requirement of larger rainwater storage due to larger household size and lower rainfall in the dry season, which reduces the BCR compared to the Australian systems. It is found that the RWH systems can be feasibly implemented at the water price of 0.01 AUD/L for all the Vietnamese scenarios and for some Australian scenarios with drinking water demand over 6 kL/day.

Full textAbstract:
Demand for water in Australia is increasing along with growing pressure to maximise the efficiency of irrigation water use and seek additional and alternative irrigation supplies. The scarcity of water supplies coupled with the need for urban communities to dispose of large quantities of treated recycled water from sewage treatment plants has led to increasing interest from urban and rural communities in the reticulation of this water for irrigating adjacent crop-production areas. Proposals to use recycled water inevitably lead to a complex range of issues that need to be addressed, including: costs and benefits of supplying an additional source of water to current or new cropping systems; optimum irrigation design and management, particularly where there are multiple sources of irrigation water; management of overflow from on-farm water storages; and environmental implications with regard to salinity, runoff, drainage, nitrate leaching, and environmental flows. Simulation models can capture many of the key factors and processes influencing irrigated crop production systems, and can play a useful role in exploring these issues. In this paper, we have described an approach that couples agricultural production system and economic models in a way that enables analysis of the likely benefits and risks of investing in recycled water, although the analysis is equally relevant to any assessment of the value of an additional source of irrigation water, particularly saline water. The approach has been illustrated with a case study of a mixed-crop farm in the Darling Downs region of Queensland, Australia, in which the farm-scale crop production, economic, and environmental implications of investing in recycled water were considered.

Full textAbstract:
Understanding the economic value of irrigation water is essential for supporting policies relating to the irrigation sector, irrigation water allocation decisions, water pricing and to compare the variable impacts of water reform within and across sectors of the economy. In this paper, we apply the residual method as a complement to other methods for determining the value of the water used over a wide range of irrigated crops in different seasons and regions of Australia’s Murray–Darling Basin. Using Monte Carlo simulation and probability theory, we estimated the combined impacts of biophysical and economic factors on the economic productivity of irrigation water use by individual activities. The estimated residual values vary across regions and in response to water availability as we would expect and warrant consideration of these factors in making any future water policy and investment decisions in different regions. As anticipated perennial (fruits and nuts, grapes) and high capital annual activities (cotton) represent the highest value water uses. Water trading from low to high value activities results in economic losses that are much lower than the proportional decline in water availability during periods of drought.

The use of Indigenous languages has been declining over the period of non-Aboriginal settlement in Australia as a result of repressive policies, both explicit and implicit. The National Policy on Languages (Lo Bianco, 1987) was the high point of language policy in Australia, given its national scope and status and its attempt to encompass all aspects of language use. Indigenous languages received significant recognition as an important social and cultural resource in this policy, but subsequent national policy developments moved via a focus on economic utility to an almost exclusive emphasis on English, exacerbated by a focus on national literacy standards. This is exemplified in the Northern Territory’s treatment of Indigenous bilingual education programs. Over recent years there have been hopeful signs in various states of policy developments supportive of Indigenous languages and in 2009 the Commonwealth Government introduced a new National Indigenous Languages Policy and a plan for a national curriculum in languages. Support for Indigenous languages remains fragmentary, however, and very much subservient to the dominant rhetoric about the need for English skills, while at the same time ignoring research that shows the importance of Indigenous and minority languages for social well-being and for developing English language skills.

This paper explores some of the factors that may contribute to the sustainable use of water on irrigated dairy farms in Victoria, Australia. The paper begins with a discussion of the principles of sustainable water use as they would apply to dairy farms in the Gippsland region of Victoria. A series of indicators are used to link aspects of sustainable water use at a regional scale, and the observable trends are discussed. Of particular interest is the way that local river systems contribute to the dairy industry in this region and the aspects of dairying and other significant regional factors that may be impacting on the sustainability of river systems in this area. The indicators are structured and analysed using the Pressure-State-Response (PSR) framework developed by the OECD, most commonly used in State of the Environment reporting. The trends highlighted by the indicator set are discussed in terms of the implications that current patterns of water use may have for possible shifts towards more sustainable water use on individual dairy farms in Gippsland.

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

The management of water resources across Australia is undergoing fundamental reform in line with the priorities identified by the Council of Australian Governments (COAG) in 1994. This includes reforms to the specification of property rights, the way the resource is shared between the environment, irrigators and other users, charges for water use and the operational management of the river systems. In New South Wales (NSW), a series of water sharing plans (WSPs) is being developed for each water source in the State including regulated rivers, unregulated rivers and groundwater aquifers. These plans, which are the mechanisms by which COAG reforms are being implemented, are being developed by community-based water management committees (WMCs). The role of the WMCs is to develop a plan that achieves a balance between environmental, economic and social outcomes. NSW Agriculture has assisted a number of WMCs by quantifying the economic impact of proposed WSP options on the irrigation community. This paper outlines the approach taken by NSW Agriculture to quantifying economic impacts on irrigators in regulated catchments and provides results of case studies in the Lachlan River Catchment which is heavily developed for irrigation.

Cotton is one of the most important irrigated crops in subtropical Australia. In recent years, cotton production has been severely affected by the worst drought in recorded history, with the 2007–08 growing season recording the lowest average cotton yield in 30 years. The use of a crop simulation model to simulate the long-term temporal distribution of cotton yields under different levels of irrigation and the marginal value for each unit of water applied is important in determining the economic feasibility of current irrigation practices. The objectives of this study were to: (i) evaluate the CROPGRO-Cotton simulation model for studying crop growth under deficit irrigation scenarios across ten locations in New South Wales (NSW) and Queensland (Qld); (ii) evaluate agronomic and economic responses to water inputs across the ten locations; and (iii) determine the economically optimal irrigation level. The CROPGRO-Cotton simulation model was evaluated using 2 years of experimental data collected at Kingsthorpe, Qld The model was further evaluated using data from nine locations between northern NSW and southern Qld. Long-term simulations were based on the prevalent furrow-irrigation practice of refilling the soil profile when the plant-available soil water content is <50%. The model closely estimated lint yield for all locations evaluated. Our results showed that the amounts of water needed to maximise profit and maximise yield are different, which has economic and environmental implications. Irrigation needed to maximise profits varied with both agronomic and economic factors, which can be quite variable with season and location. Therefore, better tools and information that consider the agronomic and economic implications of irrigation decisions need to be developed and made available to growers.

Sustainability of water use in agriculture is a line of research that has gained in importance worldwide. The present study reviewed 25 years of international research on sustainable water use in agriculture. A bibliometric analysis was developed to sample 2084 articles. Results indicate exponential growth in the number of articles published per year, with research in this field having acquired a global scale. Environmental Science and Agricultural and Biological Sciences are the main categories. Three journals—Agricultural Water Management, Water Resources Management and Nongye Gongcheng Xuebao Agricultural Engineering—published the most of the articles. China, the U.S., Australia, India and Germany produced the most research. The three institutions that published the most articles were all Chinese (Chinese Academy of Sciences, China Agricultural University and Northwest A&F University). The most cited authors were Ridoutt, Hoekstra and Zhang. The keywords most frequently used include: water-use, irrigation, water-management, water-supply, and sustainability. A network map shows three clusters that focus on the environmental, agronomic and management aspects. The findings of this study can assist researchers in this field by providing an overview of research on the sustainability of hydric resources.

Theoretical bases of modern water use, water resource potential, rational use, protection and reproduction of water resources of the region are considered. Changes in the ecological and economic system of water use in the Volyn region in market conditions are analyzed.
Anthropogenically altered natural areas, progressive pollution of human habitat, caused a deterioration in quality of life, negatively affected the demographic characteristics of the inhabitants of the planet. Water, as an important natural resource, is used in all aspects of human life and in the spheres of the national economy, has become an important factor determining the development of society as a whole.
The water management complex and especially its development must meet the socio-economic and environmental requirements of both society and the environment. The socio-economic aspect of these requirements is aimed at implementing measures and improving the territorial and sectoral structure and technologies of water use. Providing quality water to maintain the health of the population is the main goal of water use. International cooperation in the field of use and protection of water resources; taking into account environmental constraints and requirements in social and economic decisions should contribute to the stable development of regions. The Chernobyl catastrophe contaminated a large part of the territory of Volyn Polissya with radionuclides, which reduced the possibility of agricultural use of lands in the northern and north-western regions. Today it is becoming more and more important. acquires the need to develop the active use of environmental and economic tools to improve the process of water use. A number of proposals for solving an effective ecological and economic system of water use are presented
A distinction is made between losses caused to fixed assets that lead to deterioration or reduction in the amount of resources such as soil, water, fish, wildlife, buildings and structures, and losses resulting from reduced output or profits from reduced productivity of these resources. The first type of loss is simultaneous, the second - current (deduction from production). To determine the value of the simultaneous damage to natural resources, it is necessary to use their economic evaluation: land and water, forests, mineral deposits. Current losses (reduction of output, reduction of its quality or reduction of profits) can be determined by direct calculation.
Of particular importance are environmental losses of a social nature, which can only be partially measured by economic indicators: the cost of treatment, payment for sick leaves, loss of products due to illness and reduced productivity. Deterioration of health and reduced life expectancy are, of course, unacceptable and cannot be offset by any economic indicators. Damage to landscapes that worsen recreation conditions cannot be measured economically either.
Economical rational use of natural resources largely depends on the comprehensive restructuring of the entire system of production and consumption. Organize control over the level of environmental pollution; correct determination of the costs necessary to overcome the harmful effects of irrational water use. In order to reduce the negative effects of radioactive contamination, to implement a set of organizational agrochemical, agrotechnical and technological measures.
Given the great importance of water resources in the development of the national economy, not only Volyn region, but the state as a whole, the problem of balanced, scientifically sound, environmentally safe water use and dynamic development of the water complex of Ukraine is extremely important.
Key words: water bodies, water use, urbanization, pollution, purification, water supply.

ABSTRACT Background Understanding the relation between sustainability and nutrients is important in devising healthy and sustainable diets. However, there are no prevailing methodologies to assess sustainability at the nutrient level. Objectives The aim was to examine and demonstrate the potential of integrating input-output analysis with nutritional geometry to link environmental, economic, and health associations of dietary scenarios in Australia with macronutrients. Methods One-day dietary recalls of 9341 adult respondents (age ≥18 y) of the latest available cross-sectional National Nutrition and Physical Activity Survey–2011/12 of Australia were integrated with the input-output data obtained from the Australian Industrial Ecology Virtual Laboratory to calculate the environmental and economic impacts of dietary intakes in Australia. Australian adults’ dietary intakes were classified into 3 dietary scenarios: “vegan,” “pescatarian,” and “omnivorous.” Then, the relations between nutritional, economic, and environmental characteristics of the 3 dietary scenarios were demonstrated with the diets’ macronutrient composition in a multidimensional nutritional geometry representation to link the sustainability indicators with macronutrients. Results Nutrient density and economic and environmental indicators increased as the percentage of energy from proteins increased and decreased as the percentage of energy from fats increased for the 3 dietary scenarios, except for the nutrient density and water use of the “vegan” dietary scenario. Energy density increased as the percentage of energy from fats increased and decreased as the percentage of energy from proteins increased for “pescatarian” and “omnivorous” dietary scenarios. In the “vegan” dietary scenario, nutrient density and water use increased as the percentage of energy from proteins increased; however, these decreased as the percentage of energy from carbohydrates increased, instead of fats. Conclusions The study presents a new approach to analyzing the relations between sustainability indicators, foods, and macronutrients and establishes that proteins, irrespective of the source of protein, are driving dietary environmental and economic impacts.
