Abstract:

water footprint and virtual water emerge as new concepts of international water resource studies in recent years and they also become prevailing topics in the study of international water resource at present. These concepts liberate the studies from the limitation of real water viewpoint and introduce the perspective of virtual water, which makes a vital contribution to the study of sustainable use of water resource. This paper introduces the internationally leading water resource footprint model and calculation method of virtual water into the water resource system of Jinan for the first time, giving a quantified measurement of the amount of virtual water contained in the main agricultural products and industrial products of Jinan. According to the calculation and analysis based on water footprint model of Jinan, it is concluded that Jinan is a net exporter of virtual water with an import dependence factor of 0, which directly endangers the water resource security of Jinan. Therefore, it is suggested to make adjustments on virtual water trade structures and strategies to upgrade industrial structures and increase the export volume of industrial products which contained less water, so as to use the water resource in a sustainable and effective way; with limited water resource, Jinan must seek innovations on water resource management concepts in addition to saving water and making better use of water resource, to alter consumption modes and implement the strategy of virtual water by introducing “outer source”, aiming to relieve water resource shortage through virtual water trade with no efforts spared.

Abstract:

The evaluation of sustainable water resources’ utilization capacity in the Huangshui Basin is essential for effective management and development in the water-scarce regions of northwest China. This research provides valuable insights into the basin’s potential capacity for sustainable water resource use by developing a comprehensive evaluation index that addresses the following three critical aspects: climate factors, water resource systems, and socio-economic conditions. The evaluation is conducted using a dual method, as follows: the fuzzy comprehensive evaluation model and the ELECTRE III evaluation method. The results indicate that the Huangshui Basin’s water resources, as a whole, exhibit a medium sustainable utilization capacity. Climatic factors and socio-economic characteristics are the main factors affecting the sustainable utilization of water resources in the Huangshui Basin. Remarkably, both methods yield consistent results, indicating that the overall sustainable utilization capacity of the Huangshui Basin’s water resources is medium. Climatic factors and socio-economic characteristics are identified as the primary aspects influencing the sustainable utilization of water resources in the basin. Based on these findings, recommendations such as enhancing the introduction of external water resources, improving water resources’ management, and implementing comprehensive remediation efforts can help to elevate the level of sustainable water use. This research not only contributes to a deeper understanding of the basin’s water resources’ dynamics, but also serves as an important reference for informed decision making regarding sustainable utilization in the Huangshui Basin.

Abstract:

Uncontrolled and excessive use of groundwater leads to economic, social, and environmental impacts. This study investigated factors influencing the low willingness to utilize piped water. The research was conducted in Duren Sawit Village, East Jakarta. The study focused on the sources of household clean water and the factors affecting the low utilization of piped water. A qualitative research approach was employed through in-depth interviews with key informants selected using purposive sampling, and the problem was analyzed using a fishbone diagram. The study found 81% of households use groundwater, only 9% use piped water, and 10% use both sources. The findings reveal that 25% of the households using piped water still rely entirely on groundwater. The low utilization of piped water was influenced by several factors, including socio-economic conditions, environmental behavior, groundwater quality, performance of PAM Jaya, and groundwater regulations for household usage. Based on the analysis, strategies for accelerating piped water utilization were proposed, including socialization and education on groundwater conservation, quality of groundwater, improvement of PAM Jaya performance, and changes in regulations regarding groundwater use for household. Environmental behavior is identified as the primary factor influencing the high use of groundwater. Several strategies involving stakeholders are necessary to promote the use of piped water among households. Keywords: Environmental behaviour, Ground water, Ground water regulation, Piped water, Socio economic.

Abstract:

I norra Storstockholm produceras och distribueras dricksvatten av kommunalförbundet Norrvatten. Under värmeböljan sommaren år 2018 ökade dricksvattenförbrukningen bland medlemskommunerna till en sådan hög nivå att Norrvattens tillgängliga kapacitet för dricksvattenproduktion riskerade att inte räcka till. En bidragande orsak till detta, antogs vara att en stor del av den ökade vattenförbrukningen gick till bevattning och fyllande av pooler. Det är ett behov som Norrvattens verksamhet inte är dimensionerad för att hantera. I takt med dagens växande befolkning i Norrvattens medlemskommuner och en hotande global uppvärmning, förväntas risken för kapacitetsbrist tillta. Således var syftet med detta arbete att studera hur behov av vatten för bevattning och fyllande av pooler kan tillgodoses på ett långsiktigt hållbart sätt bland Norrvattens medlemskommuner utifrån de tre hållbarhetsdimensionerna. Med hjälp av litteraturstudier, intervjuer och beräkningsmodeller identifierades alternativa lösningar och effektiviseringsmöjligheter gällande tillgodoseendet av vattenbehov för bevattning och poolfyllning. Dessutom genomfördes en stickprovsundersökning med syftet att studera socioekonomiska faktorer, vid eventuell implementering av de identifierade alternativa lösningarna och effektiviseringsmöjligheterna i Norrvattens medlemskommuner. Därefter applicerades en kvantitativ analys på det erhållna dataunderlaget med väldefinierade statistiska metoder för konfidensintervall och hypotesprövningar på signifikansnivån 5 %. Resultatet visade flertalet alternativa lösningar och effektiviseringsmöjligheter var passande att implementera för att tillgodose behov av vatten för bevattning och fyllande av pooler bland Norrvattens medlemskommuner. Det berodde på en stor välvilja gentemot såväl miljön som Norrvattens verksamhet. Mer konkret identifierades en utbredd vilja att förändra konsumtionsbeteenden gällande vattenanvändning för bevattning och fyllande av pooler. Som en följd fanns också en villighet att betala mindre summor för alternativa lösningar och effektiviseringsmöjligheter för att tillgodose sådana vattenbehov. Dock påvisades även en utbredd motvillighet till kraftiga ökningar i priser och kostnader för knippade med vattentjänster, varpå mer kostsamma alternativa lösningar uteslöts som långsiktigt hållbara utifrån socioekonomiska hållbarhetsperspektiv. Därmed rekommenderades Norrvatten att fortsätta planera för utbyggnation av sin produktionskapacitet, eftersom de identifierade alternativa lösningarna och effektiviseringsmöjligheterna inte ansågs tillräckliga för att nollställa behov av dricksvatten producerat av Norrvatten för bevattning och fyllande av pooler. Samtidigt drogs slutsatsen att behovet av utbyggd kapacitet skulle kunna reduceras vid implementering av de identifierade lösningarna och effektiviseringsmöjligheterna. Dock kunde inte det reducerade behovet beskrivas i kvantitativa termer med den applicerade arbetsmetodiken. Således rekommenderades Norrvatten att i framtiden arbeten genomföra en kartläggning av detta, i syfte att erhålla värdefullt beslutsunderlag kring storlek på utbyggd produktionskapacitet.<br>In the northern part of Greater Stockholm, drinking water is produced and distributed by the municipal association Norrvatten. During the height of the summer 2018, drinking water consumption among the member municipalities increased to such an extent that the available production capacity was nearly insufficient. This was assumed to be due to major increases in drinking water consumption for garden irrigation and filling of pools, which are water needs that the production capacity is not dimensioned to handle. Furthermore, the risk of production capacity shortage is assumed to increase in the near future due to population growth and global warming. The purpose of this thesis was to examine possible approaches to supply the need for water for garden irrigation and filling of pools among the member municipalities of Norrvatten in a long-term sustainable manner with regard to the three sustainable dimensions. Based on literature studies, interviews and theoretical models, alternative solutions and efficiency opportunities of supplying water needs for garden irrigation and filling of pools was identified. A sample survey was also conducted with the aim of studying socio-economic factors regarding a potential implementation of the identified alternative solutions and efficiency opportunities among the member municipalities. Subsequently, quantitative analysis was applied to the obtained data with well-defined statistical methods for confidence intervals and hypothesis tests at the significancelevel of 5 %. The result illustrated implementable alternative solutions and efficiency opportunities of supplyingwater needs for garden irrigation and filling of pools. It was due to a large benevolence towards the environment and Norrvatten’s operations. More specifically, a widespread willingness to change consumption behaviours regarding water utilization for garden irrigation and filling of pools was identified. As a consequence, there was also a great willingness to pay smaller sums for alternative solutions and efficiency opportunities of supplying such water needs. However, a widespread reluctance to larger costs associated with water services was also identified, whereby costly alternative solutions were excluded as long-term sustainable from a socio-economic perspective. Due to this, Norrvatten was recommended to continue planning for an expansion of its production capacity, with regard to the conclusion that the identified alternative solutions and efficiency opportunities were not considered sufficient to completely reduce the need for drinking water produced by Norrvatten for garden irrigation and filling of pools. Nevertheless, it was also concluded that the need for expanded capacity could be reduced when implementing the identified solutions and efficiency opportunities. However, the reduced need could not be described in quantitative terms with the chosen methodology. Because of that reason, Norrvatten was recommended to examine this further in future projects considering that it would provide a valuable basis for operation decisions regarding expanded production capacity.

Abstract:

This thesis examines the concept of sustainability and the implications of large-scale hydroelectric development for the sustainability of communities in the Canadian portion of the Columbia River Basin. A literature review of sustainability provides a background for discussion and a working definition of sustainability is proposed for consideration throughout the study. An overview of the Canadian experience with hydro development and its ecological, social and economic impacts provides a context within which to consider issues related to sustainability. The Columbia River Basin is the setting of a case study of sustainability and hydro development in British Columbia. The Kootenay region has been affected by extensive hydro projects since the early 1900s on the Kootenay River and most significantly by large dams built on the Columbia system as a result of the Columbia River Treaty. Communities in the Kootenays have borne a large share of the impacts of these dams. The resulting degradation of fisheries, wildlife and forests has jeopardized the integrity of the region’s resource base and its capability to enhance the quality of life of those living within the Columbia River drainage basin. Future hydroelectric planning should address the sustainability of the ecological, social and economic systems affected by this land use change and ensure that local communities are included in project decision-making. Increased awareness of the consequences of large-scale hydro projects during planning stages may enable sustainable development to occur.

Abstract:

Climate change has further exacerbated long-standing water use conflicts in the Lake Velence catchment area in Hungary. The lake is the ecological, social and economic central element of the area, with water scarcity as water levels having fallen to record lows in recent years due to severe summer droughts. As a result of infrastructure developments in the 20th century and the significant waves of immigrants in recent decades, the lake and its surroundings have been heavily modified, transformed into an artificial waterbody, while land and water use has significantly altered. Besides these negative effects on water resources and the lake’s water level, settlements in the catchment area have become the top solar energy producers per housing in Hungary in recent years. The aim of this research is to identify and develop a possible inter-basin water recharge solution that meets societal needs based on the suggested development ideas formulated in questionnaire responses. A sustainable alternative of these solutions is pumping from a nearby catchment, that was evaluated in detail. Based on ecological considerations, a multi-criteria analysis summarizing nearly 100 water quality and quantity parameters was developed to ensure that water supply meets qualitative requirements. To ensure economically sustainable operating costs, the nearby solar capacities were used for pumps operation and energy storage. For energy demand and carbon emissions reduction, the uphill pumping was complemented with a downhill turbine hydropower recovery system. Several scenarios of the pumped water recharge system were considered and hydrodynamically optimized in Matlab. The return on investment of the inter-basin pumped water replenishment systems were evaluated as well as the carbon emissions to assure additional economic benefits and low carbon-footprint. A bottom-up methodology with large scale stakeholder involvement that assesses social needs and applies well-balanced the three pillars of sustainable development, can achieve a Pareto effective displacement even during the development of a water replacement system at the catchment level and beyond, on an inter-basin level. With a comprehensive methodology developed for pumped water recharge from an external catchment using existing renewable energy sources, the deteriorating social atmosphere and ecological conditions caused by climate and land use changes may be improved. In the meantime, even economic benefits can be increased, all with a low energy demand and carbon footprint, in a sustainable way.

Abstract:

The paper outlines the process of data collection and processing undertaken to develop a digital twin of the central region of Bratislava city, focused on evaluating its capacity for generating solar and wind energy on an urban scale. Data sources included airborne laser scanning, provided as 3D point clouds, older existing polygonal 3D models, and other available map documents, which were processed to generate a comprehensive polygonal model with semantic information across different layers as buildings, vegetation, water bodies, paved and unpaved terrain. The outcoming digital twin was then used to calculate solar energy potential of the city using Ladybug tools (incident radiation) and weather data from a reference year. The results were compared to the calculations using the model r.sun (total irradiation) with satellite weather data within the GrassGIS software. The newly created digital twin of the city was published as physical model with digitally projected information layers at an exhibition and it will be also published online to be used as inputs to discussions on sustainable energy strategies for smart city development. The model will be further utilized in analysis of wind energy potential using OpenFoam and in statistical models predicting urban heat island formation and popularity of public spaces evaluated by their inhabitants.

Abstract:

This paper presents an in-depth analysis of a residential solar thermal system designed for domestic hot water (DHW) production in a single-family dwelling located in Mangalia, Romania. Positioned at a latitude of 43.894� and a longitude of 28.422�, Mangalia benefits from an annual global irradiation of 1403 kWh/m?, providing favorable conditions for solar energy utilization. The study evaluates the system's performance over the course of a year, focusing on energy consumption, solar fraction, and environmental benefits. The solar thermal system in Mangalia achieves a performance ratio of 2.02, indicating that each unit of auxiliary energy input generates over two units of useful thermal energy. Notably, 64.3% of the household's total energy demand is met through solar energy, significantly reducing the reliance on conventional energy sources. Further analysis reveals that the system produces a total annual thermal output of 2661 kWh, with energy savings reaching 2801 kWh per year. These savings correspond to a reduction of approximately 1502 kilograms in CO2 emissions, underscoring the environmental advantages of solar thermal technology in this region. By integrating detailed operational data, this paper highlights the system's efficiency in harnessing solar energy, particularly in the context of Mangalia's climatic conditions. The findings emphasize the potential for optimizing system design to maximize energy efficiency and reduce environmental impact. The paper concludes with recommendations for enhancing the adoption of solar thermal systems in residential settings across similar geographical locations, contributing to the global transition toward sustainable energy solutions.

Abstract:

Objectives: 1) develop a thorough understanding of the sorption mechanisms of Pi and Po onto the Al/O- WTR; 2) determine the breakthrough range of the composite Al/O-WTR during P capturing from agro- wastewaters; and 3) critically evaluate the performance of the composite Al/O-WTR as a fertilizer using selected plants grown in lysimeters and test-field studies. Instead of lysimeters we used pots (Israel) and one- liter cone-tainers (USA). We conducted one field study but in spite of major pretreatments the soils still exhibited high enough P from previous experiments so no differences between control and P additions were noticeable. Due to time constrains the field study was discontinued. Background: Phosphorous, a non-renewable resource, has been applied extensively in fields to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Our proposal impetus is the need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings. Major Conclusions & Achievements: An innovative approach was developed for P removal from soil leachate, dairy wastewater (Israel), and swine effluents (USA) using Al-based water treatment residuals (Al- WTR) to create an organic-Al-WTR composite (Al/O-WTR), potentially capable of serving as a P fertilizer source. The Al-WTR removed 95% inorganic-P, 80% to 99.9% organic P, and over 60% dissolved organic carbon from the agro-industrial waste streams. Organic C accumulation on particles surfaces possibly enhanced weak P bonding and facilitated P desorption. Analysis by scanning electron microscope (SEM- EDS), indicated that P was sparsely sorbed on both calcic and Al (hydr)oxide surfaces. Sorption of P onto WW-Al/O-WTR was reversible due to weak Ca-P and Al-P bonds induced by the slight alkaline nature and in the presence of organic moieties. Synchrotron-based microfocused X-ray fluorescence (micro-XRF) spectrometry, bulk P K-edge X-ray absorption near edge structure spectroscopy (XANES), and P K-edge micro-XANES spectroscopy indicated that adsorption was the primary P retention mechanism in the Al- WTR materials. However, distinct apatite- or octocalciumphosphatelike P grains were also observed. Synchrotron micro-XRF mapping further suggested that exposure of the aggregate exteriors to wastewater caused P to diffuse into the porous Al-WTR aggregates. Organic P species were not explicitly identified via P K-edge XANES despite high organic matter content, suggesting that organic P may have been predominantly associated with mineral surfaces. In screen houses experiments (Israel) we showed that the highest additions of Al/O-WTR (5 and 7 g kg⁻¹) produced the highest lettuce (Lactuca sativa L. var. longifolial) yield. Lettuce yield and P concentration were similar across treatments, indicating that Al/O- WTR can provide sufficient P to perform similarly to common fertilizers. A greenhouse study (USA) was utilized to compare increasing rates of swine wastewater derived Al/O-WTR and inorganic P fertilizer (both applied at 33.6, 67.3, and 134.5 kg P₂O₅ ha⁻¹) to supply plant-available P to spring wheat (TriticumaestivumL.) in either sandy loam or sandy clay loam soil. Spring wheat straw and grain P uptake were comparable across all treatments in the sandy loam, while Al/O-WTR application to the sandy clay loam reduced straw and grain P uptake. The Al/O-WTR did not affect soil organic P concentrations, but did increase phosphatase activity in both soils; this suggests that Al/O-WTR application stimulated microorganisms and enhance the extent to which microbial communities can mineralize Al/O-WTR-bound organic P. Implications: Overall, results suggest that creating a new P fertilizer from Al-WTR and agro-industrial waste sources may be a feasible alternative to mining inorganic P fertilizer sources, while protecting the environment from unnecessary waste disposal.

Abstract:

In the global search for the right alternative energy sources for a more sustainable future, hydrogen production has stood out as a strong contender. Hydrogen gas (H2) is well-known as one of the cleanest and most sustainable energy sources, one that mainly yields only water vapor as a byproduct. Additionally, H2 generates triple the amount of energy compared to hydrocarbon fuels. H2 can be synthesized from several technologies, but currently only 1% of H2 production is generated from biomass. Biological H2 production generated from anaerobic digestion is a fraction of the 1%. This study aims to enhance biological H2 production from anaerobic digesters by increasing H2 forming microbial abundance using batch experiments. Carbon substrate availability and conversion in the anaerobic processes were achieved by chemical oxygen demand and volatile fatty acids analysis. The capability of the matrix to neutralize acids in the reactors was assessed using alkalinity assay, and ammonium toxicity was monitored by ammonium measurements. H2 content was also investigated throughout the study. The study's results demonstrate two critical outcomes, (i) food waste as substrate yielded the highest H2 gas fraction in biogas compared to other substrates fed (primary sludge, waste activated sludge and mixed sludge with or without food waste), and (ii) under normal operating condition of anaerobic digesters, increasing hydrogen forming bacterial populations, including Clostridium spp., Lactococcus spp. and Lactobacillus spp. did not prolong biological H2 recovery due to H2 being taken up by other bacteria for methane (CH4) formation. Our experiment was operated under the most optimal condition for CH4 formation as suggested by wastewater operational manuals. Therefore, CH4-forming bacteria possessed more advantages than other microbial populations, including H2-forming groups, and rapidly utilized H2 prior to methane synthesis. This study demonstrates H2 energy renewed from food waste anaerobic digestion systems delivers opportunities to maximize California’s cap-and-trade program through zero carbon fuel production and utilization.

Abstract:

This report investigated the interplay between water quality, sanitation, hygiene and gender by examining distinct variables of water quality and their varying impacts on gender like reported water-related illnesses of males and females, and the consequences of water quality, sanitation, and hygiene on menstrual hygiene practices, particularly focusing on a low- and middle-income country- LMICs. This report presents the key findings, outlining a framework and guidance for examining gender-specific impacts stemming from poor water quality and WASH practices through a piloted case study in Abeokuta City, Nigeria, to serve as a preliminary guide for conducting comprehensive, site-specific assessments. The piloted Differential Impacts Assessment, DIA framework is a 5-step approach, guiding the evaluation of gendered impacts from method design to the field activities, which include water sampling and laboratory analysis, public survey, and health data collection, to the data and gender analysis. The focus on low- and middle-income countries underscores the importance of DIA in such regions for better health and socioeconomic outcomes, promoting inclusive development. The study results reveal unsettling, largely unseen gender disparities in exposure to health-related risks associated with non-utility water sources and highlight pronounced differences in water source preferences and utilization, the burden of water sourcing and collection, and health- and hygiene-related practices. Specifically, this preliminary assessment indicates an alarming inadequacy in accessing WASH services within the pilot study area, raising considerable doubts about achieving SDG 6 by 2030. While this finding is worrying, this report also discusses the lack of a standardized protocol for monitoring water-related impacts utilizing sex-disaggregated data, shedding light on the unseen global-scale gendered impacts. The report warns about the water safety of non-utility water sources. Without point-of-use treatment and water safety protocols, the water sources are unsuitable for potable uses, potentially posing compounded health risks associated with microbial contaminations and high calcium content, particularly affecting boys. Girls are likely the most affected by the repercussions of water collection, including time constraints, health implications, and safety concerns. Men and boys face a higher risk related to poor hygiene, while women may be more susceptible to health effects stemming from toilet cleaning responsibilities and shared sanitation facilities. Despite the preference for disposable sanitary pads among most women and girls, women maintain better menstrual hygiene practices than girls. This age-specific disparity highlights potential substantial health risks for girls in the near and distant future. Enhancing women's economic status could improve access to superior healthcare services and significantly elevate household well-being. The report calls for targeted actions, including urgent planning and implementation of robust water safety protocols for non-utility self-supply systems and mainstreaming gender concerns and needs as the “6th” accelerator for SDG 6. The piloted methodology is scalable and serves as an introductory guide that can be further refined to explore and track site-specific differential health and socioeconomic effects of inadequate water quality, especially in locales similar to the study area. The report targets policymakers and donor organizations advocating for sustainable water resource development, public health, human rights, and those promoting gender equality globally

Abstract:

arbon dioxide (CO₂) has a negative impact on the climate, but it also has several practical areas of use. Many industrial processes emit CO₂ in high concentrations, which could be captured to mitigate emissions while also creating valuable products. One example of such a process is biogas upgrading – a process separating renewable gases, where methane is taken care of for use as vehicle fuel or industrial energy carrier, while CO₂ is released into the atmosphere. The aim of this project has been to chart alternatives and technologies for taking care of green CO₂ from biogas upgrading, so-called carbon capture and utilization (CCU), and to investigate the conditions for applying these in a Swedish context. The work has been guided by the following research questions: * How large is the current and future potential for CCU from biogas production? * What are the possible areas of use for CO₂ from biogas production? * What factors influence the choice of areas of use for CO₂ from biogas production? * How large is the environmental benefit of CCU from biogas production? To answer these questions, calculations of potentials, a multi-criteria assessment and a life cycle assessment were carried out, based on the Swedish biogas production. A reference group comprising representatives for large Swedish companies within biogas production and biogas upgrading technology was used to enable coproduction and networking between the research group and the business sector. The production of CO₂ from biogas was estimated to 160,000 ton/year in 2020, with potential to increase to 540,000 – 840,000 ton/year in a few years and 790,000 – 1,230,000 ton/year in a longer perspective, as a consequence of an expected increase in the Swedish biogas production. A large share of the CO₂ is however produced at relatively small upgrading facilities, which could limit the feasibility for CCU due to high costs for investment and operation. Adding hydrogen to transform all the CO₂ into methane could potentially increase the methane production from biogas from 2 to 3 TWh/year in a short-term perspective and from 11 to 17 TWh/year in a long-term perspective, given sufficient access to hydrogen. Other ways of utilizing CO₂ from biogas include production of biomass or chemicals, concrete curing, pH control of process water and use as a refrigerant. The choice of CCU options can be influenced by environmental, technical, economic and policy-related aspects. From the biogas producers’ perspective, methanation is the option that is the most compatible with the existing production system and business model, while other solutions usually involve another actor taking care of the CO₂. Hydrogen is required for methanation as well as for production of chemicals. Another limiting factor are the high purity requirements on all CO₂ that is distributed and sold on the market. The geographical distribution of the production plants can also be a challenge. Several CCU options can improve the environmental performance of biogas by replacing fossil-based products. The potential climate impact is the lowest if the CO₂ is methanized with renewable hydrogen or mineralized in concrete, but other forms of environmental impact can also be reduced by applying these or other CCU options. For comparison, permanent storage of CO₂ in geological formations (carbon capture and storage, CCS) only reduces the climate impact, while it increases other forms of environmental impact. Furthermore, permanently storing biogenic CO₂ can make it difficult to reduce the use of fossil CO₂ and transition to a more sustainable society. The need for carbon in many essential processes and products suggests that biogenic CO₂ should be utilized and not stored.
