Full textAbstract:
Doctor Legum - LLDWater is at the very core of sustainable development, critical for a thriving people, planet and prosperity. Water is regarded as a public good which is fundamental for health and life. Water is so important that it was debated as being a basic human right on many international platforms. Water access has plagued many parts of the world for a long period of time. In recent years, there have been increasingly urgent warnings of a global water crisis, as the human species consistently uses more water than is sustainably available. The international community tried to work towards overcoming these water-related issues by establishing the then Millennium Development Goals (hereafter referred to as MDGs), with MDG7.C focusing on access to safe drinking water. Even though MDG7.C was achieved in part, issues still remained regarding water access and quality. Sustainable Development Goal 6 (hereafter referred to as SDG 6) was then introduced and the scope of SDG6 is much wider than its predecessor, since the water access and scarcity problems are still prevalent today. The 2030 Agenda for Sustainable Development includes a dedicated goal on water and sanitation that sets out to ensure availability and sustainable management of water and sanitation for all. SDG6 expands the MDG focus on drinking water to now cover the entire water cycle, including the management of water, wastewater and ecosystem resources, with water at the very core of sustainable development. The goal has, in essence, extended to include a much broader spectrum of issues that need to be solved which, in essence, unravels even more challenges along the way. As a result, it is imperative to determine whether SDG6 can allow for actual sustainable development in terms of freshwater resources. Thus, this thesis will discuss the advent of the Sustainable Development Goals (hereafter referred to as SDGs), in particular SDG6, as well as analyse how SDG6 impacts on International Environmental Law, with particular emphasis on International Freshwater Law. The main aim of this research is to determine whether the creation and implementation of SDG6 can result in overall freshwater sustainability and whether this can result in the furtherance of sustainable development.

Full textAbstract:
Water is an essential resource for sustainable development, however it is not often taken into account. In order to find effective and lasting solutions to the problems related to water resources, it is required a new form of governance and management paradigm. This new paradigm is included into the concept of Integrated Water Resources Management (IWRM), which has been defined by Global Water Partnership GWP , as "a process which promotes the coordinated management and development of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of ecosystems".

Full textAbstract:
Sustainable, robust, and resilient water resources planning and management (WRPM) has emerged as a major concern, not only for decision makers and water utilities but also for academic researchers. A water resources system is very complex since its enormous number and diverse components are connected and interrelated. To establish effective management and planning for the water resources system, decision makers and planners can disaggregate large water resources systems into multiple scales based on geographical boundaries and the management and planning goals.
Arizona’s water resources system can be divided into basin, state, planning area, and local planning area scales. Each scale requires a different approach and models depending on the WRPM goals. This dissertation takes a comprehensive view of sustainable, robust, and resilient WRPM for multi-scale Arizona water resources systems (state, planning area, and local planning area scales).
This dissertation is composed of three studies with four journal articles that address sustainable, robust, and resilient WRPM. First, for the state and planning area scale, a large food-energy-water system model is developed for Arizona using a system dynamic modeling approach. Using the model, effectiveness of potential alternatives including graywater reuse, rainwater harvesting, demand reduction, and groundwater importation that promise sustainable water use are evaluated.
Second, at the regional planning area scale, impacts of various strategies on the robustness and resilience of regional water supply system (RWSS) during major component failure for a region in southwest Tucson, AZ are assessed. The strategies include (1) restricting water demand, (2) constructing pipelines as alternative water supply pathways, (3) building water tanks as backup water storages, and (4) maintaining the Central wellfield as a backup source.
Finally, the impact of network topology within water distribution system (WDS)/water distribution network (WDN) on (1) the accuracy of the first-order second-moment (FOSM) approximation when it is employed as a nodal pressure head uncertainty estimation method and (2) WDN robustness and resiliency. To that end, a quantitative WDS classification scheme that classify a WDS based on its function and network topology are developed. Using the classification scheme, network topology within WDS is identified and used for the analyses.

Full textAbstract:
Water supply service delivery has been recognised as a complex challenge facing communities in developing countries. Its particularly serious in sub-Saharan Africa where a significant proportion of the population still lack basic access to safe drinking water supply. Over the years, many externally supported community-managed water facilities have failed to deliver sustainably. This results not only in a loss of financial investment but also constitutes a real threat to people’s health and well-being. Therefore, this study aimed to explore options for innovative water service delivery approach that can support vibrant water supply provision as well as provide a guidance framework for sustainable water service delivery in Nigeria. Due to the socio-technical complexity of the research, the mixed method approach was found to be the most suitable research method after extensive considerations and reviews of other several available research methodologies. The study found that the hand-dug wells (HDW) have enormous potential in sustainable water service delivery to households within the proposed framework arrangement. This research successfully presented a unique model, based on the concept of HDW self-supply, using rope pump technology in conjunction with a community-based water resource management concept. The proposed approach led to the production of a set of Guidance Frameworks that will aid planning and implementation of a proposed solution. This was validated with key stakeholders and it applicability was rated highly relevant in the water sector. The approach did not only address the question of technical and financial sustainability but also make a case for environmental sustainability. Hence, ensuring that meeting present domestic water needs will not jeopardise the ability of future generations to meet their own needs. Further research was recommended to ensure wider applicability of the model.

Full textAbstract:
Water management is a global challenge. Important facts of current concern in the water sector are: water scarcity threatened by the increasing consumption, safe drinking water supply resources threatened by climate changes and pollutants discharged from anthropogenic activities; and the accelerated urbanisation demanding adequate water supply together with the increasing wastewater generated by the growing urban population. These issues are becoming an imperative need that could be effectively addressed through adaptive water management strategies for the sustainable development of the societies worldwide. Metropolitan areas exemplify the rapid increase of urban population within a relative small area, which consequently results in the overexploitation of water supplies. Together with this overexploitation, human health could be threatened due to the water-health nexus in terms of water quality and quantity. The specific case study of this research: the Metropolitan Area of Merida (MAM) in Yucatan, Mexico has been analysed in order to exemplify the use of a decision maker’s tool to improve public health through the identification of major water pollutants and correlate them with waterborne diseases documented in epidemiologic statistics. The focus of this research was on two indicator contaminants: Faecal coliforms as microbial indicator of water quality, representing the non-conservative pollutants, and nitrate as chemical indicator of water quality, an example of a conservative pollutant that may persists in the groundwater for decades. Seven engineering interventions have been tested to identify most suitable management strategies through the following steps: 1. Quantify pollutants in the aquifer with the Sustainable Integrated Water Management Model (SIWMM), using a system dynamics approach; 2. Outcomes of the model served to quantify a) Public health risks posed from faecal coliforms through Quantitative Microbial Risk Assessment (QMRA), and b) Economic savings associated with pollutants reduction, 3. Develop cost benefit analysis of selected interventions, and 4. Identify the most suitable intervention in order to assist decision makers to cope with a sustainable supply of safe water and an integrated water management. The model framework developed in this thesis identifies the installation of soil absorption systems into septic tanks at household level, and installation of treatment plants for livestock wastewater as the most cost-benefit interventions of substantial positive impacts on groundwater quality and public health and, in addition, economic benefits.

NoThis paper reflects on what is meant by interdisciplinary engagement in the context of two integrated urban water management research programmes in the UK and New Zealand. Different extents of interdisciplinary engagement in research teams are conceptualised on a continuum that ranges from rhetorical intentions to joint research. We discuss how interdisciplinary working in research programmes is shaped through the processes of bidding, research management and production of outputs. The paper concludes that if higher levels of interdisciplinarity are desired, they need to be specifically funded and planned for. In particular, funders may need to provide flexibility in relation to interdisciplinary outputs, which may be hard to specify at the start of a research programme.

Full textAbstract:
The world experiences large-scale ecosystems degradation in an every part of the planet - in rich as well as in and poor parts. Unstable economic conditions together with weak law enforcements make low income countries face more severe forms of natural destruction. This draws the attention on the need to design economic policies that are environmentally sound and while at the same time ensuring the well-being of their inhabitants in economic, social and natural settings. A number of countries in Central and Eastern Europe and Central Asia have experienced a unique historical period of transition from communist regimes to free democratic societies. This has been followed by numerous effects on their financial situations as economic hardships caused by the collapse of economies injected by the assistance from the Soviet and committees of socialist countries mutually aiding each other, opening up of opportunities as private ownership and market liberations. Not all countries succeeded in liberalizing their economic structures and reforming economic and political environments. Simultaneously, the natural environment underwent various effects, both positive and negative, after the Iron Curtain fell and exposed destructing effects of command and control economy. Mongolia has experienced all the hard aspects of the transition and started to climb up on the income ladder from the low income to the lower middle-income list of the World Bank, but also seen many negative price aspects of development. Water resources have been severely degraded in recent years due to anthropogenic impact. However, there are reforms taking place in water sector institutions that have recently attracted wide attention nationwide.This thesis will give detailed picture on current state of water resources in the country and the system that coordinates them. The Environmental Kuznets Curve (EKC) is used as an approach to highlight the relationship between water resource quality and income per capita in Mongolia. This is followed by a detailed discussion on water institutions development and the coordinating mechanisms badly needed among sectors involved. The research suggests that collaborative actions are important if sustainable water management is to be reached. More generally, I recommend further research issues on the generated topic as my thesis is one of the first discussions coupling the EKC and institutional theory aspects together.

Full textAbstract:
Khartoum State in Sudan is subject to the erratic and intense rainfall during the short rainy season and dryness and heat throughout the rest of the year. High intensity rainstorms with a short duration have become more frequent in the area during the last two decades resulting in cities inundation and flash floods in the rural parts. On the other hand, the dry season means hot weather in the urban parts and water shortage in the rural part. Rural areas are dependent on the runoff water brought about by the seasonal streams as a source of water. For this study, Khartoum City Center and Seleit area were taken to investigate the application of water harvesting in the urban and rural areas, respectively. Accordingly, the hydrological characteristics and the specification of the potential water harvesting sites and systems were examined.
For Khartoum City Center, characteristics of the drainage system were examined using ArcGIS platform. It is found that the drainage system covers 42% of the area with total capacity of 24000 m3. Daily rainfall data for urban meteorological station were used to calculate the probability and the return period of the rainfall, as well as the potential runoff. Rainfall probability of occurrence was calculated applying Gumbel distribution method for extreme events that were arranged according to the Peak-over-Threshold method. The potential runoff that could be generated from a certain rainfall was calculated using the Natural Resources Conservation Services method provided by the United States Department of Agriculture (US-NRCS). Accordingly, the curve number was calculated depending on the land use/land cover and the hydrological soil group. Consequently, the weighted curve number is found to be 94%, indicating dominant imperviousness. 13.1 mm rainfall depth produces runoff volume equal to the drainage system capacity with return period of one year; whereas more than four folds the drainage system capacity is produced by 30 mm rainfall depth that is considered the threshold for raising flood hazard. Six potential sites for roof rainwater harvesting were selected. Accordingly, it is found that, the application of roof water harvesting in 18% and 72% of the commercial and business district buildings can accommodate the runoff resulting from the 13.1 and 30 mm rainfall depth, respectively. Hence, impounding rainstorm water would help managing the urban runoff water, and consequently, the stored water could be used for making more green areas that will enhance the urban environment.
Three watersheds of ephemeral streams (wadi), namely Wadi El Kangar, Wadi El Seleit, and Wadi El Kabbashi make up Seleit area. Distinct maps were prepared in ArcMap for the calculation of the potential runoff and the specification of the appropriate water harvesting sites and systems. The Wadis watersheds areas are found to be 540, 344 and 42 km2 for Wadi El Kangar, Wadi El Seleit and Wadi El Kabbashi, respectively. Daily rainfall data of rural meteorological station were classified into three groups representing the soil dry (AMCI), moderate (AMCII), and wet (AMCIII) moisture conditions; the respective CNI, CNII, and CNIII values were calculated accordingly. The weighted CN values indicate high runoff potential within the three soil moisture conditions. Accordingly, the rainfall thresholds for runoff generation for AMCI, AMCII and AMCIII conditions are found to be respectively 18.3 mm, 9.1 mm and 4.4 mm for Wadi El Kabbashi and 22 mm, 11 mm and 5 mm for both Wadi El Seleit and Wadi El Kangar. El Kangar dam subwatershed was used for calibrating the potential runoff calculated by the NRCS method. Since the Wadis are ungauged, Google Earth and GIS platforms were used to calculate geometrically the volume of the dam reservoir water for three years. This volume was compared to the annual runoff calculated by the NRCS method. Consideration to different factors was made to locate the potential water harvesting sites. Accordingly, water harvesting systems for fodder and crop plantation; sand storage surface or subsurface dams; or groundwater recharge, were specified. The socio-economic study revealed that the financial capacity, if any, of the villagers is very limited. Thus, the financial source for the construction of the suggested potential water harvesting or the rehabilitation of the existing ones is questionable. Hence, other potential financial sources are needed to help executing water harvesting projects in the region, e.g. Khartoum State Government.
Applying water harvesting in Seleit area is found to be promising. Improving the livelihood of the villagers by applying runoff water harvesting could assure better water accessibility, better income generation from farms production, and allocation of time for other activities, e.g. education. This would be reflected in reduced migration to nearby cities and stabilized market supply of agricultural and animal products. Therefore, the development of the rural part is of great benefit to the development of Khartoum State, as long as the interdependency and mutual benefit between the rural and urban areas, represented by the local food and labor market, remain exist.

Full textAbstract:
Miami-Dade County implemented a series of water conservation programs, which included rebate/exchange incentives to encourage the use of high efficiency aerators (AR), showerheads (SH), toilets (HET) and clothes washers (HEW), to respond to the environmental sustainability issue in urban areas. This study first used panel data analysis of water consumption to evaluate the performance and actual water savings of individual programs. Integrated water demand model has also been developed for incorporating property’s physical characteristics into the water consumption profiles. Life cycle assessment (with emphasis on end-use stage in water system) of water intense appliances was conducted to determine the environmental impacts brought by each practice.
Approximately 6 to 10 % of water has been saved in the first and second year of implementation of high efficiency appliances, and with continuing savings in the third and fourth years. Water savings (gallons per household per day) for water efficiency appliances were observed at 28 (11.1%) for SH, 34.7 (13.3%) for HET, and 39.7 (14.5%) for HEW. Furthermore, the estimated contributions of high efficiency appliances for reducing water demand in the integrated water demand model were between 5 and 19% (highest in the AR program). Results indicated that adoption of more than one type of water efficiency appliance could significantly reduce residential water demand.
For the sustainable water management strategies, the appropriate water conservation rate was projected to be 1 to 2 million gallons per day (MGD) through 2030. With 2 MGD of water savings, the estimated per capita water use (GPCD) could be reduced from approximately 140 to 122 GPCD. Additional efforts are needed to reduce the water demand to US EPA’s “Water Sense” conservation levels of 70 GPCD by 2030. Life cycle assessment results showed that environmental impacts (water and energy demands and greenhouse gas emissions) from end-use and demand phases are most significant within the water system, particularly due to water heating (73% for clothes washer and 93% for showerhead). Estimations of optimal lifespan for appliances (8 to 21 years) implied that earlier replacement with efficiency models is encouraged in order to minimize the environmental impacts brought by current practice.

Full textAbstract:
A strategic management of water is integral for any society aiming at moving towards sustainability. This thesis aims to provide a common understanding of how water management should be considered within sustainability constraints, using ‘backcasting’ from basic sustainability principles as a compass. With a common language, a constructive dialogue is then possible to unify all stakeholders to move together towards sustainability. To answer the research question “How can an interaction with water stakeholders be strategically developed to progress toward the service of water in a sustainable society”, a methodology based on Sustainability Life Cycle Assessment, the Template for Sustainable Product Development and Multi-Stakeholder Platforms has been utilised within one domestic and one industrial water user case study in Blekinge, Southern Sweden. In this locality, water is regarded as abundant in volume. Yet it was revealed that what is consumed by society is not water as such; but the purity of water. Within this context, opportunities to move towards sustainability have arisen and the case study organizations were able to utilise improvements in reporting and operations. Economic activity such as new infrastructure, pollutant trading schemes and product accreditation are amongst the many concepts identified as potential steps towards the service of water in a sustainable society.

Full textAbstract:
Indigenous peoples in North America have a long history of understanding their societies as having an intimate relationship with their physical environments. Their cultures, traditions, and identities are based on the ecosystems and sacred places that shape their world. Their respect for their ancestors and 'Mother Earth' speaks of unique value and knowledge systems different than the value and knowledge systems of the dominant United States settler society. The value and knowledge systems of each indigenous and non-indigenous community are different but collide when water resources are endangered. One of the challenges that face indigenous people regarding the management of water relates to their opposition to the commodification of water for availability to select individuals. External researchers seeking to work with indigenous peoples on water research or management must learn how to design research or water management projects that respect indigenous cultural contexts, histories of interactions with settler governments and researchers, and the current socio-economic and political situations in which indigenous peoples are embedded. They should pay particular attention to the process of collaborating on water resource topics and management with and among indigenous communities while integratingWestern and indigenous sciences in ways that are beneficial to both knowledge systems. The objectives of this paper are to (1) to provide an overview of the context of current indigenous water management issues, especially for the U.S. federally recognized tribes in the Southwestern United States; (2) to synthesize approaches to engage indigenous persons, communities, and governments on water resources topics and management; and (3) to compare the successes of engaging Southwestern tribes in five examples to highlight some significant activities for collaborating with tribes on water resources research and management. In discussing the engagement approaches of these five selected cases, we considered the four "simple rules" of tribal research, which are to ask about ethics, do more listening, follow tribal research protocols, and give back to the community. For the five select cases of collaboration involving Southwestern tribes, the success of external researchers with the tribes involved comprehensive engagement of diverse tribal audience from grassroots level to central tribal government, tribal oversight, on-going dialogue, transparency of data, and reporting back. There is a strong recognition of the importance of engaging tribal participants in water management discussions particularly with pressing impacts of drought, climate change, and mining and defining water rights.

Full textAbstract:
The exponential growth of the world population led by the geographic expansion of urban areas in developing countries has put massive pressure on natural resources especially land and water. Water supply and water scarcity remain one of the major challenges facing the industrializing world. The United Nations forecast further increase in population which, in the absence of management and policies, will inevitably put more resources at risk. Changing climatic conditions causing more frequent and intense rainfall will also affect water management systems in the vulnerable urban areas of developing countries. The goal of this study was twofold; first analyze the patterns of water consumption in the rapidly growing city of Lagos, Nigeria and use them in a System Dynamics (SD) model to make projections about future demand. The second part used remote sensing to quantify the contribution of extensive land use/cover change to urban flooding. Land use/cover dynamics over the past decade was analyzed using satellite imagery provided by Landsat Thematic Mapping (TM). Unsupervised classification was performed with false color composite using the Iterative Self-Organizing Data Analysis (ISODATA) technique in a Geographic Information Systems (GIS). The study area was divided into four different land use types during image classification: bare land, built-up area, water bodies, and vegetation. For water demand, two different scenarios of population growth including 5.5% and 2.75 % annual increase were considered. The results showed that water demand dropped by 67% of its current value when losses in distribution were reduced by 20% and population annual growth rate kept at 2.75% over the study period. Bare land and water bodies lost 1.31% and 1.61% of their current area respectively while built-up area grew by 1.11%. These changes in land use/cover changes led to a 64% increase in average surface runoff, mostly attributable to increasing surface imperviousness and the absence of an adequate urban drainage system. This paper intends to assist the authorities of the city of Lagos who adopted a master plan in 2010 as a road map to reduce to city’s vulnerability to flooding and close the gap between water demand and water supply by 2050.

Full textAbstract:
Cape Town is experiencing its worst drought in recorded history. Notwithstanding that the Western Cape has always been a water scarce region, it is this current drought that has brought home the area’s inherent vulnerability and highlighted the governance issues. The world wherein South Africa’s water governance was created is very different to the world we find ourselves in today. It is a world of uncertainty and unpredictability not contemplated in water governance comprised of legislation, policy, guidelines and practice. The current water governance constructs a conventional approach based upon predictability and certainty and is no longer appropriate to meet today’s new challenges. Consistent with this conventional approach, Cape Town’s municipal water supply is almost completely dependent upon surface water which makes it even more vulnerable to drought than if its supply was comprised of a variety of water supply options. With surface water sources fully exploited and storage opportunities within the urban edge limited alternative water supply options must be more seriously considered and the water governance reformed to accommodate its use. Water governance is the focus of reform because it is the framework for infrastructure planning and therefore controls the resultant system, infrastructure and management. This thesis interrogates the current water governance as the starting point before firstly discussing the proposed incremental approach towards a decentralised, hybrid system for water infrastructure and secondly, identifying specific areas where intervention is necessary for implementation.

Full textAbstract:
Denna fältstudie kommer att undersöka betydelsen av regnvattenanvändning som vattenförsörjnings alternativ. Hur kan hållbara innovativa lösningar tas fram för att lösa vattenförsörjningen på Sri Lanka? Efter lidandet av mer än 30 års inbördeskrig och efter de omfattande skadorna från tsunamin 2004, står nu Sri Lanka inför många utmaningar rörande landets återuppbyggnad. Tillgången till vatten är den viktigaste grundläggande förutsättningen för ett fungerande samhälle. I landets torra zon är det långa perioder av torka då vattenkällor sinar och inget naturligt vatten finns att tillgå. Detta trots att det under monsunen kommer tillräckligt med regn för att täcka vattenbehovet om det skulle samlas på ett optimalt sätt. Avrinningskoefficienten är här mer än 60% outnyttjat regnvatten. I ett flertal lyckade projekt har man samlat regnvatten i RWH system för senare användning. Människor i dessa områden saknar kranvatten eftersom detta område ej är täckt av vattenförsörjningsnätet. Detta gör att dessa människor har en positiv inställning till att ha RWH system..I den våta zonen, och då speciellt i Colombos stadsmiljö som denna studie handlar om, är situationen annorlunda. Här har de flesta invånare kranvatten. Det kommunala kranvattnet är högt subventionerat av regeringen vilket gör att kostnaden är låg för användarna samt ökar vattenkonsumtionen. Invånarna känner inget ansvar för vattenresurserna eftersom den gemena uppfattningen är att det är en evig källa. Majoriteten av hushållen ser inget skäl till att installera RWH på grund av den låga lönsamheten. Trots att det finns ett förordnande att det ska ingå ett RWH system, så följs inte detta. Saknande av uppföljningsplikt anges som orsak av vatten styrelsen. Kostnaden för att behandla och leverera vatten till invånarna är väldigt hög och är mycket energi krävande. Det finns ett behov av enorma investeringar för att rusta upp och bygga ut både vattenverken och vattennätet för att klara av att möta det växande invånarantalet i Colombo området. Ett annat problem är att 40% av hushållen i Colombo saknar avloppsanslutning. De leder sitt avloppsvatten direkt eller efter en septi-tank ut i jorden eller havet.Om medvetenheten kring dessa frågor ökar, samt att förhållandet mellan kranvattnets kostnad och RWH justeras med ändringar i subventionerna, kunde en hållbar lösning på vattensituationen med såväl ekonomiska som miljövinster ske.Resultatet av denna studie är att RWH får ses som ett komplement när det gäller vattenförsörjningen för hushållens del. Fokus bör istället ligga på industrier, sjukhus, skolor, kommunala byggnader och andra byggnader med stora vattenbehov och med de största möjligheterna att uppnå optimalt resultat.Studien visar också på en hållbar lösning på avloppshanteringen. Den visar DWWT och dess fördelar.The field study will investigate the importance of Rain Water Harvesting (RWH) as a water supply option. How can sustainable innovative solutions be developed to solve the water problem of Sri Lanka? Suffering from more than 30 years of civil war and damages after being struck by the tsunami 2004, Sri Lanka faces many challenges to recover and rebuilt the country. The access to water is the most important need for a civilization´s existence. In the dry zones of the island people suffer from long drought periods with dried up wells and no natural sources for water. However the rainfall during the monsoon, even in these areas, is more than enough to provide the water needs if properly collected, thus the run-off coefficient is more than 60%. Several projects with rain water harvesting in so called RWH systems have been implemented with success. Because these areas are not covered by the water supply net and therefore have no tap water, the people are very positive to having the RWH system. In the wet zones and especially in the urban environment of Colombo the situation is different. Here most of the people have treated pipe-borne tap water. The metered tap water is highly subsidized by the government which makes the cost low for the users and increases the water consumption. The citizens do not feel a responsibility to be careful with resources since the common opinion is that water is a never ending source. The majority of the households find no reasons for installing a RWH system because it´s low economic profits. Even if there is a legislation that demands all new buildings should have a RWH system not many households have installed these systems. However the cost to deliver and treat this water is very expensive for the government and demands a lot of energy. Huge investments need to be done in both the treatment plants and the pipe-line net to meet the growing population in Colombo area. Another problem is that 40% of the households today in Colombo have no sewage connection but lead their wastewater directly or after a septic tank into the ground or the sea. If the awareness regarding these concerns could be improved and the conditions between tap water costs and RWH be adjusted with changes in the subsidized system, a sustainable solution to the water situation in Colombo with both economic and environmental benefits could be found. The result from the case study is a recommendation about installing RWH as a complimentary source of water for the households. And investments in RWH systems should be focused to industries, hospitals, schools, municipal buildings and other public buildings with a high water demand and with the best possibilities for optimal results. Further the case study treats a sustainable solution to the sewage situation. It shows the Decentralized waste water treatment plant (DWWT) and its advantages.

Full textAbstract:
Pervious pavements in car parks and driveways reduce peak discharge and the volume of runoff flowing in to urban drains and improve the water quality by trapping the sediments in the infiltrated water. This reduces the risk of pollutants such as suspended solids and particle bound chemicals such as phosphorous, nitrogen, heavy metals and oils and hydrocarbons entering receiving waters. The key objectives of the study are to establish relationships between rainfall and pervious pavement runoff and quantify improvements to infiltrated stormwater quality through the pervious pavement. The field experimental results were used to calibrate the PCSWMMPP model and to develop water flow and quality improvement transfer functions of the MUSIC model for concrete block and turf cell pavements. The research reported herein has demonstrated that pervious pavements can be introduced as a sustainable stormwater management initiative and as a key Water Sensitive Urban Design feature to deliver numerous benefits to the environment. The outcomes from the study will be useful in designing environmentally friendly car parks, pedestrian paths, light traffic drive ways, sporting grounds and public areas in the future. Land developers and local government authorities will be major beneficiaries of the study which has increased the understanding of the use of pervious pavements and explored a number of issues that previously inhibited the wider use of pervious pavements in practice.

Full textAbstract:
Delivering improved water services in small towns in low-income countries encompasses particular challenges. Often considered too large to be effectively community managed , small towns may also be too small, with too limited economies, to benefit from utility style professionalism and economies of scale. The most recent paradigm, that financially sustainable water services will be best achieved through the Demand Responsive Approach , has been complemented in Ghana, the focus of this study, through the development of a variety of management models, community, local government, national utility and private providers, to deliver DRA. Taking advantage of this unusual situation, in having a wide range of different functioning models in one country at the same time, this research has sought to investigate these management models with respect to effectiveness, equity, financial sustainability and efficiency of services delivery. However, the context in which all of these models operate relates to consumers effective demand, key to delivering a demand responsive approach. A second objective, necessary to validate any results relating to management models, has therefore been to investigate households actual demand for improved and alternative sources of water. Data for the research was gathered from examples of the four management models in use in Ghana, from eight small towns spread across the length and breadth of the country. The methodology incorporated key-informant interviews, user observations, household surveys and an analysis of relevant documents of operators and policy makers. The fieldwork was undertaken in two separate periods, designed to ensure that any effects of dry and wet season variations, which influence water supply delivery as well as demand, were adequately captured. The research found that none of the management models in use in small towns in Ghana could be considered to be significantly more effective than any other; overall, households demonstrated a limited demand for water supply with even this demand distributed among a number of sources, both formal, improved and alternative, traditional sources; this demand was not so much a function of affordability, rather a clear choice as to where to use limited resources mobile phone access absorbing three times the amount spent on water. Whilst certain management characteristics were found to make a difference, leadership in particular, no one model was able to influence the overarching water source effect, that is the cost of formal supply (surface water costing approximately three times more than ground water), relative to access to alternative, free supplies in the context of limited overall demand for water.

Full textAbstract:
The Lake Urmia positioned in a closed basin in north-west Iran, positioned at altitude 1250 m above the sea level, and has been rapidly drying since 1990. The lake water level has declined to 1271.58 m in 2008 from the last highest record 1277.80 m in 1994. The lake water volume has fluctuated during the observation period and shows a drop from of 32 to 14.5 million cubic meters, while the lake salinity has increased from 205 to 338 g/l due to the evaporation and water inflow reduction. In the Lake Urmia basin, there has been an increase in public awareness of the possible environmental threat and the unpleasant socio-economical consequences on the region’s inhabitants. The main aim of this study is to assess the current water use pattern in the Urmia Lake basin system with emphasis on the agricultural sub-system, and to propose adaptive measures and sustainable water management scenarios. The study shows that the main cause for these changes are the diversion of rivers and streams for agricultural irrigation; agriculture is a sector with one of the highest water demands, and frequent drought in early 2000s exacerbated the situation. In addition, a growing population and the increased development of agricultural land has led to an increase in unsustainable practices which have an unpredictable impact on the Lake Urmia ecosystem. This study investigates sustainable water use strategies for Lake Urmia basin, and considers economic and environmental factors, including the loss of valuable ecosystems that highlights social and ethical issues for the current and coming generations.

Full textAbstract:
Climate change, caused by anthropogenic greenhouse gas emissions, is one of the most important issues of our time. It is often overlooked that up to 5% of a cities electrical energy consumption is required to pump water in the water distribution system. This thesis describes how pump scheduling can contribute to a more sustainable energy management of water distribution systems. The analysis is enabled though a new convex formulation of the pump scheduling problem, which provides theoretical optimality bounds, a requirement for the comparison of different energy management strategies. The problem formulation is then expanded to include variable speed pumps. The first energy management method investigated is the provision of demand response to the grid by adapting pump operating schedules. Demand response from water distribution systems is shown to provide reserve energy at lower cost and with less than half of the greenhouse gas emissions 240gCO2e/kWh of the competing technologies. Installing variable speed pumps in a network is shown to increase the possible applications of demand response and increase the revenue potential. Next, the trade-offs between cost and emission reduction are analysed in a range of energy supply scenarios in the UK, in the current grid as well as possible future scenarios. It is found that greenhouse gas emission cost must rise significantly, above £100 t/CO2, before affecting scheduling decisions. Furthermore, it is shown that the pump utilisation rate, the share of time the pump operates, is key to profit from possible changes in the energy supply. Finally, the operating schedule of pumps powered in part by an on-site wind turbine is optimised. This analysis calculates the cost of uncertainty in the wind power forecast in renewable energy generation. A stochastic optimisation method is presented that reduces the cost of uncertainty.

Full textAbstract:
This study examines the barriers to sustainable water resources management in water vulnerable, yet a mining booming area. The case study is conducted in Omnogovi province of Mongolia in Nov-Dec 2016. This study presents how the Omnogovi province manages its water with increased mining and examines what hinders the province from practicing sustainable water resources management and examines the involvement of residents in the water resources management of Omnogovi province. Qualitative approaches such as semi-structured interviews, participatory observation and literature review were used in this study. This study demonstrates that the water resources management of Omnogovi province is unsustainable in this time period, yet the implementation of IWRM approach has improved the water resources management of the province. The barriers to sustainable water resources management in Omnogovi province are inefficient governance and poor enforcement of law, today. Despite it, data-scarcity and transboundary water issues might become barriers to practice efficient water resources management in the province. The involvement of residents in water resources management of Omnogovi province is deficient, yet the implementation of participatory approach and establishment of RBC might improve the participatory governance. The study shows IWRM can improve the water resources management of a developing country, yet it can be time-consuming, costly and challenging to implement in a country, which is still in socio-economic and political transition.

Full textAbstract:
'Water stress' is a term used when the pressures of urbanisation and the uncertainty of climate change on hydrological limits and capacities can no longer be overcome by traditional supply-oriented engineering responses because of their economic and environmental costs. It can be argued that the key alternative water policy responses are occurring with the changing role of development and Catchment Management Planning (CMPg) to a more 'catchment consciousness' water management model. In England and Wales the emergence of 'water stress' in the 1990s has coincided with the national launch of CMPg and renewed interest in development and water issues. Thus the research question sought to investigate how the National Rivers Authority (NRA) as a statutory environmental agency sought to improve and integrate river management by extending its influence to development planning through Catchment Management Planning (CMP) between 1991 and 1996. The particular areas of outcome focused on were water quality improvement, water resource management and flood protection, major NRA functions. The research findings demonstrated that there were different types of development response linked to water issues, scale of implementation and potential contribution to city form. The most important factor in the type of response was the water issue, with the flooding relationship being most advanced and water resources the least. The CMPg process assisted by supporting the promotion of water policies in DPs and creating a new context (involving stakeholder involvement and consensus building) in which to implement these policies. CMPg was found to be having the greatest impact in areas where no previous consensus over particular water issues had existed, and thus had begun to act as a new arena for debate on the problems and solutions required.

Full textAbstract:
La Mancha Plain lies in the core of Spain and partially stretches over the Guadiana River Upper Basin (UGB), is one of the most arid regions of the Iberian Peninsula, indeed “La Mancha” in Arabic means “the dry”, and also houses a vast Aquifer that has supported the related numerous marshlands and hydro-ecosystems in harmony with the human development till the 1970s, when the “Agrarian Green Revolution” commenced. Land reclamation over River and lagoon beds joined to the irrigation implementation of more than 150.000 Ha have badly bled the water resources to the maximum usable limit, lowering the phreatic table down to 60 meters, provoking a serious ecological damage for the 25.000 Ha of wetlands highly dependent on shallow phreatic levels. Recently, Nature granted the wettest period ever registered in the area (2009-2012) which caused an incredible natural replenishment of that Aquifer deficit. However, even though several costly plans and policies have been undertaken, it is still pending to effectively control the extractions, to manage the Aquifer within a portion allowing a certain continuous upwelling to enliven the Guadiana River real spring, and also, to adjust the essential agriculture sector to the environmental conditions and carrying capacity of the system.

Full textAbstract:
The provision of water, wastewater and stormwater infrastructure is an essential ingredient of cities. However, questions are being raised about the type and form of urban infrastructure, for economic and environmental reasons. Traditionally these techologies have offered linear solutions, drawing increasing volumes of water into cities and discharging waste at ever increasing levels, causing escalating stress on the
environment. In addition the costs of water infrastructure provision and replacement, both in the developing and developed world, is becoming prohibitive. In response, a new paradigm has been called for and new solutions are emerging that have been labelled as Integrated Urban Water Management (IUWM). This concept can be considered to consist of both technical and philosophical dimensions, and represents a new form of professional praxis. However, the adoption of these techniques and concepts is constrained by the inertia of the existing urban water systems. It is therefore argued that the introduction of any change must occur across a number of dimensions of the technoeconomic system of the city. These dimensions-artefacts and technical systems (i.e. the technology and knowledge systems), professional praxis and socio-political context (i.e. institutions, culture and politics) and biophysical realities and world views (i.e. the environment and underlying values) - provide a framework for analysis of the change process - both how it is occurring and how it needs to occur. This framework is used to illustrate the link between environment values and the process of technological innovation, and points to the need for the emerging values and innovations to be institutionalised into the professional praxis and socio-political context of society. Specifically, it is argued that a new form of transdisciplinary professional praxis is emerging and needs to be cultivated. A broad review of the literature, an evaluation of selected emerging technologies and three case studies are used to illustrate and argue this position. These examples show the potential economic, social and environmental benefits of IUWM and provide some insight into the potential which this approach has to influence the form and structure of the city and at the same time highlighting the institutional arrangements required to manage urban water systems.

Full textAbstract:
This thesis investigates water use within the Australian and New Zealand gold mining sectors. Process and non-process water audit strategies were conducted to study site water use efficiencies and explore how different water management techniques influence extraction rates, water through-put and re-use cycles. Water audit findings were verified by simulating the data in WaterMiner, a coal mine based software modeling program. This provided the basis for recommendations towards water management planning at four case study mine sites (Kalgoorlie, Jundee, Tanami and Waihi) and an indication that WaterMiner water flow alternatives result in an average of 17.5% increased water efficiency.
At the Kalgoorlie Consolidated Gold Mine the incorporation of simulated flows into its current water management could reduce extraction from three of its main water sources by 1,479 ML/year, equating to a reduction in water abstraction of 31.2%. At Newmont's Jundee Gold Mine implementing suggested alternate flows in the operation could reduce its annual water usage by the lowest margin of all the case study sites, resulting in water savings of 8% or 175 ML/year. For Newmont's Tanami Granites Gold Mine and the Waihi Gold Mine in NZ indicative water savings were 329 ML/year or 17.2% of site water demand, and 1,031 ML/year or 14.6%, respectively.
The ultrasonic techniques and methodologies described in this thesis present replicable water auditing processes for water managers in other mine sites to consider. The water auditing results and approaches developed and verified by the WaterMiner program, provide a sound basis for water use efficiencies and management planning in the gold mining industry.

Full textAbstract:
Impacts of climate change on the already severely strained freshwater resources of approximately 1000 inhabited islands in the Pacific Ocean are of great concern. The Western Pacific region is one of the world’s most vulnerable when it comes to risk of disaster particularly for the several of the low-lying coral islands. Impacts have already been felt regarding the security of water resources that would directly impact agriculture, forestry, tourism and other industry-related sectors. The ironic and tragic aspect of the environmental crisis of greenhouse emissions is the fact that those parts of the world least responsible for creating the water security issues are the first to suffer its consequences. Pacific Island Nations are responsible for only 0.03 percent of the world’s carbon dioxide emissions, and the average island resident produces only one-quarter of the emissions of the average person worldwide.
Utilizing the historical data, the evidence of change in water quality and access on Guam has been examined. All indicators except for the precipitation support the hypotheses that climate change trends are impacting Guam’s water security. This will eventually weaken Guam’s resilience. As a result of this research and its recommendations, a sustainable freshwater resources management plan, for a water-secured Guam can be produced. Adaptive management provided here is based on a process that can measure the resilience of Guam to the issue of water security.

Full textAbstract:
This thesis puts forward the benefits of a transdisciplinary approach to environmental management, using urban New Zealand use and value of freshwater as a case in point. In New Zealand, the deficiencies of urban water management have become more evident over the last decades spurring a long process of water reform. Changing precipitation patterns are increasing the risk of flooding events and water shortages; there are regional and seasonal stresses on freshwater resources; and people's attitudes and expectations are poorly understood. Existing pricing structures are obscuring signals of both water shortages and wasteful practices. This research examined and mapped people's awareness, perceptions, attitudes and preferences in Auckland City and Christchurch City; two communities with different cultural, ecological and political systems of water management. A system-based contingent valuation method was developed to establish the level of acceptance for including ecosystem services as a part of the water infrastructure equation in the two communities. By eliciting a willingness to pay for water related ecosystem goods and services, values were coupled with price and consumption. It was found that the old mindset seeing water as a free gift from nature prevails in some communities even in the presence of higher environmental awareness, encouraging unsustainable consumption and potentially creating political inertia about water management reforms. It was found that there was a positive willingness to pay for ecosystem services in both cities, and that motivational factors were stronger predictors than socioeconomic variables for accepting the proposed pricing structure in Christchurch. The systems approach developed in this thesis identified cultural-ecological city identity constructs as having a strong potential for building community expectations for ecologically sustainable water management. It is recommended that local water authorities are established consisting of tangata whenua, stakeholders and experts from social, economic and ecological fields, and to be charged with developing local visions for water management and restoration programmes for water related ecosystems. It is recommended that pricing should include terms for full-cost recovery, resource rent, scarcity and investment in natural capital.

Full textAbstract:
This thesis reports the results of a three year cross disciplinary investigation of the water resources of a small headwater catchment and their role existing and future in the livelihoods of the local community. In addition the potential for micro-catchment management to improve the water resources and water based livelihoods of the catchment community was also examined. Physical examination of the shallow aquifer revealed higher than expected levels of groundwater recharge, matched by high levels of naturally occurring discharge. A groundwater modelling study suggested that this discharge was caused by both deep and shallow rooted vegetation, rather than by drainage losses, and that the catchment aquifer was largely isolated from any larger regional groundwater system. Research into the historical development of the catchment community revealed an ongoing process of agricultural intensification, driven by increasing population and expectations. One manifestation of this intensification is a rapid development of groundwater resources for small scale irrigation. The study suggested that the increased development of and reliance on water points exploiting shallow groundwater resources could lead to increased risk in dry periods associated with generally low groundwater levels. The work highlighted the crucial importance of correct siting and design of water points if widespread failure is to be avoided. However, it also suggested that irrigated agriculture could be sustainably increased at least ten-fold by using suitably sited high yielding water points. Finally, a prototype decision support system was developed using Bayesian Belief Networks, and this was used to integrate the physical and human aspects of the study within a single framework. This framework was then used to examine the likely affects on livelihoods of adopting a micro-catchment management approach to managing groundwater resources.

Full textAbstract:
Reliability of water supply in the urban setting has become essential for communities to function and thrive. It is needed for more than mere human consumption and well-being. Although modern cities have water treatment and distribution systems, pressures from urbanization, population growth and the anticipated pressures of climate change are affecting the quality of water supply and the reliability of treatment and distribution systems. There is therefore an urgent need to take appropriate measures to improve the resilience of water supply systems before the impacts are irreversible.
Improving the resilience of water supply systems can be a challenge. In the United States, there is increased awareness of aging, overtaxed and under designed water infrastructure. To date, resilience planning has been principally focused on improving preparedness and the restoration of critical services in communities following extreme events, such as hurricanes, earthquakes or terrorism, and less so on the slow-moving consequences of climate change, perceived as a less urgent threat. All these issues – increased pressure of urbanization and population growth, deteriorating infrastructure, together with the consequences the impacts of climate change may have on water systems and the apathetic view of the need for action – are what make the development of a solution difficult.
This research proposes Integrated Urban Water Management as a new water management paradigm as one that can withstand contemporary issues as well as future climate threats, while increasing water supply resilience for communities. This research (1) focuses on analyzing the urban water cycle for potential vulnerabilities, (2) seeks to understand the benefits and challenges of integrating water infrastructure, (3) tests the level of sustainability in an IUWM system, (4) identifies critical thresholds ‘slow-moving’ climate change on water supply infrastructure, (5) performs a system-wide water and salt balance and (6) tests the system for resilience to salt water intrusion.
Since coastal communities are subject to higher population densities, demands on resources, and exposed to greater threats than inland communities, this project utilizes a coastal community with integrated water infrastructure as a basis to better understand the benefits as well as the potential challenges of the proposed future paradigm (IUWM).
The results of this research show that IUWM offers many options for sustainable practices as well as adaptability, a key aspect of resilience. The conclusions drawn from the scoping study, case study and modeling of water and salt flows within the urban water cycle offer relevant and transferable lessons for water management in coastal cities while they approach uncertain and alternative climate futures.

Full textAbstract:
Densication and intensied precipitation patterns due to climate change, has increased the need for sustainable stormwater management. Sustainable stormwater management can be implemented as blue-green infrastructure (BGI), which integrates green features for natural inltration and detention such as green roofs and rain gardens. Through the use of BGI, added values can be provided as ecosystem services. Authorities and organizations in Sweden imply the need for valuation of ecosystem services for future integration in decision-making. This thesis include monetary estimations of ecosystem services within the use of a cost-benet analysis (CBA), for two alternatives of stormwater management in Masthuggskajen, Gothenburg. The applied valuation methods are methods commonly used in economic analysis. The ecosystem services identied and monetarily estimated as benets within this project were ood protection, water treatment, air quality regulation, noise regulation and added recreational value. The result of the CBA indicated that the most protable alternative was considered to be the implementation of BGI rather than underground solutions. The ecosystem services contributing the most to the result was added recreational value, noise regulation and ood protection. A sensitivity analysis was concluded by altering the value of costs and benets. Further analysis of the uncertainty in monetary estimates is of importance in order to integrate ecosystem services in decision-making. The diculty in covering the full extent of benets generated by BGI indicates the need of complementary tools in decision-making. However, this study highlights the importance of inclusion of ecosystem services in decision-making.

Full textAbstract:
This research study explored the appropriate sustainable governance management systems for South African socio-economic conditions. This was achieved by investigating the current governance and management of water boards in performing their business and water services provisioning at municipal level. Municipalities are the third sphere of government in South Africa and are found at local levels of governance. They are businesses that provide running water as legislated by the Constitution of the Republic of South Africa, 1996. Water boards are public institutions established in terms of the Water Services Act, 108 of 1997 (WSA) and listed as Schedule 3 part B: National Government Business Enterprise in terms of the Public Finance Management Act 29 of 1999. They are accountable to the national government through the Department of Water Affairs. Their responsibility is to support municipalities where water-provisioning challenges are eminent. They report annually to national parliament on their performance within a specific financial year. Water boards are currently able to perform their operations in selected jurisdictions as contracted by municipalities. They are struggling in managing and governing their water business while striving to achieve improvements in water service coverage, operating efficiency and service delivery. The aim of the research study was to investigate areas affecting the sustainability of governance management systems for water boards in relation to the improvement of service delivery in South Africa. The analysis of age and gender factors and the conditions affecting governance are explored. The research used the qualitative and quantitative methods to analyse the research questions. Prior to the commencement of the study, the researcher performed an intensive desktop study involving the use of dated and recently published material related to governance and management of the water institutions in developed and developing countries. During the desktop study, national and international accredited journals were prioritised to obtain related and relevant similar information to the water governance and management of water institutions. In addition, a case study was undertaken in Ficksburg in which water boards provided an intervention in resolving the water crisis, since the provision of water is a basic service at local government. This area experienced both water shortage and a poor quality of water. With regard to qualitative methodology, participatory forums were used to delineate the research context and premise. The study population consisted of individuals who were in the business of water boards with special reference to water management and board of directors for a population of 1 000. Of the 500 questionnaires sent out, 419 were returned. The data were analysed using the statistical software package, Statistical Package for Social Sciences (SPSS). The results and recommendations are presented based on the identified objectives of the study. The study’s findings provide information for transformation and improvement in the performance of water boards in South Africa when striving for sustainability in management and governance. The findings reveal the need for improvements in the involvement of females in the business of the water boards. The findings confirm the outcomes of previous studies regarding the slow implementation of affirmative action and transformation processes as required by legislation. Furthermore, the results reveal that the factors and conditions affecting sustainability of the water boards need to be prioritised to improve the management and governance aspects of water boards. These include the appropriate selection of members of the boards of directors, water boards' committees that are guided by legislation in their operations and the maintenance of proper financial management (collection of revenue, implementation of appropriate financial strategies and striving for positive clean audit). Water boards are encouraged to strengthen their intergovernmental relations in order to make their mandate known across all spheres of government. Service delivery should be approached “from source to tap and tap to source” to promote high-quality provision of water. The water boards should be accountable to the municipalities for the provision of delegated operations. The Department of Water Affairs exercises an oversight role to ensure the sustainable provision of the services. However, the study concludes that without a strong management and a sustainable governance approach, water boards will not be able to carry out its water developmental mandate. The practical framework that was developed in this study provides management and governance tools for sustained provisioning of water to advance transformational and developmental needs and the application of legislations. The results in the study have a direct impact on the codes of practice and regulations on employment equity in implementing the Employment Equity Act of 1998, Intergovernmental Relations Act of 2005, Companies Act of 2008, National Water Act of 1998, and Water Services Act of 1997. Therefore, the practical implementation of this framework will enhance water as a transformational and developmental feature in addressing the social, environmental and economic services.

Full textAbstract:
This dissertation works to create a clearer understanding of sustainability in water policy. Current water policy in four US cities was compared to a matrix of recommended sustainability themes that have been presented in the literature to determine the extent of which these themes have been implemented into water policy. To best analyze policy for sustainability it is necessary to look at the policy of cities that are considered sustainable. This was determined by a city’s inclusion in “Most Sustainable US Cities” lists. The two cities that best represented sustainability were Austin, TX and San Francisco, CA. The research also included cities that are not considered leaders in sustainability but are similar in demographics, population, and state; these two cities are Fort Worth, TX and San Jose, CA. Finally, the same matrix was applied to the state policy to establish how state policy influences city sustainability.
The results of this study add to the current knowledge in this field as it contributes a current analysis of sustainable water policy. The final findings compile the themes into a sustainability pyramid framework of common, uncommon, and rare sustainability. It appears that the ‘sustainable’ cities have included more uncommon and rare themes than the traditional cities, while common themes are implemented across the board. Common themes are those that are traditionally associated with sustainability – themes like conservation, reuse, and reducing pollutant impact on water sources. In order increase sustainability, cities should apply more of the themes from the top of the pyramid.

The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the Olifants-Doorn Water Management (WMA) area. The general approach was to attempt to reconcile monitoring requirements with existing resources, while investigating the hypothesis that regional monitoring should focus on resource status monitoring. Groundwater science needs to focus on clarifying the sustainability options available to the stakeholders, and monitoring the chosen option. This can best be done by adopting an adaptive management approach to both the management of the groundwater resources, and the management of the monitoring programme.

Full textAbstract:
Global climate change, environmental degradation and demographic changes has emphasizedthe sustainable development of Mekong river basin. The research uses the theoreticalframework that sustainable development in the transboundary water resource management ismost likely to be achieved through the policy making based on the ‘regional approach’ andthe ‘alternative development strategy.’ The aim of this research is to investigate themanagement of Mekong river basin within the theoretical framework and to assess theprospect of sustainable development. The Mekong River Commission (MRC) and itsprograms, hydropower development in the upstream and the downstream and the geopoliticalsituation of the Mekong region are reviewed for the analysis. In result, although MRC hasstressed the principle of sustainable development, the limitations such as the damconstructions in the both upstream and downstream, donor influence, legal restrictions of the1995 Mekong Agreement and limited implementation of the participatory approach indevelopment programs remain as the constraints to achieve sustainable development. TheBuild-Own-Transfer type of privatized hydropower development in the downstream is achallenge to the environmental and social sustainability by accelerating the process of thedam building process. MRC’s the most prioritized strategy to introduce the ‘Integrated WaterResource Management’ implies the basin-wide management of water resource management,yet the complexity of respective national interests have to be added as a concern in thetransboundary context. The absence of China and Burma in MRC is a critical weakness toapply the regional-approach in the development policy. In the case of the upstreamhydropower development, the decision making has been done unilaterally without theaccountable and transparent process. As China considers the Mekong in the relation to theenergy production and oil transportation, the securitization of the Mekong will affectnegatively on the future participation of China in MRC. A positive trend can be derived fromChina’s ambition to become a regional power to replace the donors in MRC, and thisstrategic realism will strengthen the regional cooperation between China and other riparianstates though MRC.

Full textAbstract:
In my thesis essay I have researched the impact of water management on the outcome of peace negotiation and treaty in the case of Israel and Syria. My research question was “How should the water resources of the Golan Heights be addressed in a coming peace treaty between Israel and Syria for this treaty to be sustainable?”. I emanated from the theory advocated by researchers Ohlsson, Homer-Dixon and Gleick, arguing that the detailed incorporation of water management in negotiations as well as in a final peace treaty between countries is crucial for these to be sustainable. I used this theory in analysing the extended data related to the two countries’ water resources and water policies, as well as two previous rounds of negotiation. I came to the conclusion that for any future negotiation to lead to a sustainable peace agreement between the two countries, it is crucial for them to establish very detailed stipulations on the shared water resources. Both Israel and Syria are in great need of accessing and controlling water resources, however Israel is much more dependent than Syria on the waters of the Golan Heights. When an internationally recognized borderline between the countries in the future will be established, it will by default be situated on or closely connected to vital water resources. Therefore the water management, including use of and withdrawal from these resources needs to be clearly regulated, otherwise conflict might rise again between the two countries. If water management would be included in the peace treaty in as thoroughly manner as the theorists suggests, this would enable the treaty to become sustainable, as well as make feasible the resolution of related conflicting matters.

Full textAbstract:
Groundwater in the Alwahat region of Libya is a non-renewable resource, and is the only source of water for agricultural land in the region. The aim of this research is to explore the contemporary performance of the groundwater sector in Libya and to develop a strategy for providing a sustainable groundwater resource to achieve a social, economic and environmentally-sustainable water future. Perceptions about groundwater sustainability are elicited from 769 local stakeholders. This analysis is conducted using a triangulated mixed-methods design, to interpret the collected information. Conflicts of opinion among the stakeholders are exposed, highlighting controversies concerning their levels of satisfaction with water supplies, their awareness of water sustainability issues, their understanding of recent changes in groundwater quality and the environmental impact of water use, and future solutions to prevent water misuse. In addition to this, there is an examination of what officials report as the extensive misuse of water due to the installation of pumps, and some of the farmers abstracting drinking water from the network for irrigations well as digging deeper into the ground and sinking more wells, which abstracts excessive amounts of water and lowers the groundwater level. The known reasons of groundwater contamination discussed in this study include oil operations, increased salinity in water soil infiltration, and crop fertilization which is established by reliable sources; however no contemporary quantitative or qualitative monitoring data is available. The majority of the farmers, domestic users, and officials agree that the environment around Alwahat is adversely affected by oil company activities. Education, training, and guidance are encouraged by all the stakeholders as a solution to prevent water misuse. In effect, farmers resort to changing their crop types and the metering of wells to conserve water; but, the government officials disagree. The hydrologist’s solution is to stop the expansion of the farms. Penalties for excessive water were introduced, but increasing the price of water was not popular among domestic consumers. The findings make the following recommendations: (a) Stakeholders should adopt the principles of the Dublin statement, recognizing a holistic approach to sustainable water, linking local, social and economic issues with ecosystem protection; (b) The Libyan Government should develop a sustainable water strategy with long-term ambitions; (c) Further efforts from water legislators to clarify regulations and their implementation; (d) Long-term quantitative and qualitative monitoring of local groundwater resources, and the formulation and use of integrated models to support future water management. (e) A pricing structure to be implemented, using a water tariff system for domestic, agricultural, and industrial users.

Full textAbstract:
Stormwater provides a direct link between urban infrastructure and the urbanised natural environment. In particular, highway drainage presents a high risk of pollution when compared to other urban land use areas (Ellis et al., 2012); introducing heavy metals, suspended solids and hydrocarbons to urban waterways. This research investigated runoff from the R300 highway, located in the greater Cape Town area. The City of Cape Town Management of Urban Stormwater Impacts Policy requires the treatment and attenuation of stormwater from developments within the city, and proposes Sustainable Drainage Systems (SuDS) as a means to achieve this (CSRM, 2009b). SuDS are structural and process controls that attenuate surface drainage, improve runoff water quality, provide amenity and deliver ecosystem services. This study characterized the R300 runoff through a sampling program and modelling exercise in order to provide an indication of the ability of SuDS to manage highway runoff in South Africa. Sediment and runoff samples were collected from the road surface and an undeveloped parcel of land adjacent to the highway. The sampling results showed that heavy metals, suspended solids and phosphorus are present in significantly greater concentrations in road runoff compared to rainwater from the same area. The concentration of aluminium, copper, lead, zinc and phosphorus exceed the Department of Water and Sanitation's water quality guidelines for aquatic ecosystems in excess of 1000%. The concentration of heavy metals, phosphorus and fats, oils and greases was significantly greater in road sediment compared to sediment from the surrounding area. Barring copper, all contaminant concentrations in the road surface sediment are less than the maximum concentration required to protect ecosystem health. The R300 rainfall-runoff response was modelled in PCSWMM to evaluate the performance of SuDS such as infiltration trenches, bioretention areas and swales for managing highway runoff in terms of quantity and quality. The modelling exercise showed SuDS to be a viable means to attain the City of Cape Town's stormwater objectives, provided that SuDS are implemented in treatment trains along the entire road length.

This document includes three completed publications to represent Urban Agriculture as a ideal solution to meet the UN Sustainable Development Goals. The first publication (Weaver, 2017a) provided in Chapter Two examines the stormwater Best Management Practices (BMP) modelling parameters for the current EPA Stormwater Management Model (SWMM) as the first step to developing Urban Agriculture BMPs. The second publication (Weaver, 2015) provided in Chapter Three highlights how many high-rated scholars have identified agriculture as a critical driver for the planetary systems impacts we find with community development. The third publication (Weaver, 2017b) provided in Chapter Four breaks down a completely new definition for Urban Agriculture, as the foundational works disagree on meaning, resulting in an ambiguous definition. Together, these publications encourage engineers to model Sustainable Development options with green infrastructure (Weaver, 2017a), distinct from the Planetary Systems impacts of other contemporary options (Weaver, 2015), with a greater understanding of the social capital to engage stakeholders in meeting the UN Sustainable Development Goals (Weaver, 2017b).

Full textAbstract:
Physically decentralised water management systems may contribute to improving the sustainability of urban water management. Any shift toward decentralised systems needs to consider not just physical system design but also social values, knowledge frames, and organisations, and their interconnections to the physical technology. Four cases of recent Australian urban water management improvement projects were researched using qualitative methods. Three cases were of decentralised water management innovation. The other was of a centralised system, although decentralised options had been considered. These cases were studied to identify institutional barriers and enablers for the uptake of decentralised systems, and to better understand how emerging environmental engineering knowledge might be applied to overcome an implementation gap for decentralised urban water technologies. Analysis of each case focused on the institutional elements of urban water management, namely: the values, knowledge frames and organisational structures. These elements were identified through in-depth interviews, document review, and an on-line survey. The alignment of these elements was identified as being a significant contributor to the stability of centralised systems, or to change toward decentralised systems. A new organisational home for innovative knowledge was found to be common to each case where decentralised innovation occurred. ??Institutional entrepreneurs??, strong stakeholder engagement, and inter-organisational networks were all found to be linked to the creation of shared meaning and legitimacy for organisational and technological change. Existing planning frameworks focus on expert justification for change rather than institutional support for change. Institutional factors include shared understandings, values and organisational frameworks, and the alignment of each factor. Principles for, and examples of, appropriate organisational design for enabling and managing decentralised technological innovation for urban water management are proposed. This research contributes to the understanding of the institutional basis and dynamics of urban water management, particularly in relation to physical centralisation and decentralisation of urban water management technologies and, to a lesser extent, in relation to user involvement in urban water management. Understanding of factors that contribute to enabling and constraining decentralised technologies is extended to include institutional and organisational factors. New and practical pathways for change for the implementation of decentralised urban water systems are provided.

Full textAbstract:
This research deals with setting up a GIS and hydrological modeling based approach for sustainable water resources management in the West Bank of Palestine. This water sustainability approach took into consideration the water balance, the social, the economic, the demographic, the environmental, and the institutional components in order to enhance and promote the sustainable development in Palestine, both on the short and long runs. To evaluate the water balance component, a methodology was introduced to create the Water Sustainability Map (WSM). Since the groundwater is currently the only accessible water source by the Palestinians, the WSM is represented by the Aquifer Sustainable Yield (ASY) which is equivalent to the annual renewable recharge of the various aquifer formations in the West Bank. The ASY was determined by integrating the watershed boundaries derived from the Digital Elevation Model (DEM) with the available hydrological and meteorological data by using GIS. This GIS based approach was used to create the rainfall, evapo-transpiration, and runoff coverages by interpolating their values from the measured parameters. The total estimated ASY using this GIS approach was 679.7 MCM/Yr. which constituted the upper limit for the overall water use in all assumed future water demand scenarios. This approach fulfilled the demographic, social, and economic water sustainability components by proposing water demand scenarios for the period from 2005 to 2025 based on the gradual increase of population and their per capita water use, the available water infrastructure, and based on the value of water where priority was given to the household water use. This approach fulfilled the environmental dimension of water sustainability by studying the water quality and identifying the locations with high pollution indicators for various water use purposes and recommending ways to prevent the environmental degradation and groundwater pollution. This approach fulfilled the institutional dimension of water sustainability by reviewing the current institutions dealing with water management and distribution, recommending options to enhance their efficiency, and finally by proposing some options to save additional water in the West Bank.

Full textAbstract:
Water shortage is one of the greatest challenges that the world faces today. International and national water initiatives are increasing simultaneously with the number of implemented drinking-water projects. The provision of sustainable safe drinking-water supply is here conceptualized through the Sustainable Livelihood Approach with the view of helping poor people secure their essential basic needs, improve their quality of health and increase their livelihood opportunities. However, a lot of drinking-water projects do not end up with satisfactory outcomes. Widespread results have demonstrated low quality water resource management, worsened access to water supply, constructions shutting down and not the least, that consumers have not been able to take advantage of their new basic drinking-water systems. Projects have often failed in remote rural areas in developing countries where strong social norms, cultural values and power structures prevail. The research is based on identifying and analyzing to what extent past drinking-water projects have addressed public participation and been aware of social, cultural and structural surrounding factors. By using Gunilla Åkesson’s sociological framework the research also addresses the role and value of sociological aspects in drinking-water projects. It is found that past projects have often failed to include public participation and lacked situational awareness to a sufficient extent. The research show the importance for projects staff, managers and technicians to take into account social behaviors, cultural norms and societal structures in the local environment and to provide local people with health awareness and education. By taking this into consideration it would enable people to change their behavior and take advantage of the improved drinking-water systems provided for them. In conclusion, there is a need to address more sociological aspects in water resource management in order to promote sustainable safe drinking-water supplies in remote rural areas in developing countries. It can be argued that this is not only applicable in drinking-water projects but also in other areas of fields within grass root development work.

“All countries are vulnerable to climate change and instability in weather patterns but the poorest countries and the poorest people within them are most vulnerable, being the most exposed and having the least means to adapt” (IMF and World Bank Development Committee, 2006). African cities, as other cities around the world, are prone to flooding within in urban areas. The increased flooding from climate change, could have seriously destabilising effects for Africa (Commission for Africa, 2005). Climate records shows that most of Africa warmed by approximately 0.7°C during the twentieth century (IPCC Working Group II, 2001). Future changes in rainfall will depend greatly on the influence of global warming. In addition, a United Nations World Water Report states that in the beginning of the twenty-first century, the Earth with its diverse and abundant life forms (including over six billion humans), is facing a serious water crisis. Water needs to be conserved in any way possible. (United Nations World Water Report, n.d.). This study aims to explore the role in which floodingin urban landscapes can be addressed, but simultaneously stored for future use. It argues that the negative element of flooding can rather be used, i.e the water could be conserved and used in the build environment, rather than inhibiting social, economic and ecological factors. The pilot project in this stage can at the same time, serve as an urban generator. An innovative solution (urban water park) is analysed and tested and serves as a possible outcome to address flooding problems within an African city (Maputo, Mozambique). Afrika, 2005).Stede in Afrika, soos in ander in die wêreld, is onderhewe aan vloedrampe in stedelike areas. Die toenemende vloedegevalle, tesame met die impak van klimaatsverandering, kan uiterse destabilisering vir die Afrika kontinent inhou (Kommissie vir Afrika, 2005). ‘n Klimaatsrekord, bewys dat gedurende die twintigste eeu, ‘n groot deel van Afrika onderworpe was aan ‘n hittetoename van omtrent 0.7°C (IPPC Werksgroep II, 2011). Toekomstige veranderinge in reënval sal grootliks afhang van die invloed van aardsverwarming. Ter aanvoering van die argument word daar adisioneel toegevoeg dat die Verenigde Nasies se Wêreldswater Verslag die volgende aanlas: dat die aarde, met sy diverse en verskeidenheid van lewende wesens (wat oor die ses miljioen mense insluit), aan die begin van die een-en-twintigste eeu onderworpe sal wees aan ernstige watertekorte. Water moet dus in alle moontlike maniere gespaar word (Verenigde Nasies se Wêreldswater Verslag, geen datum). Die studie beoog om die rol van vloede in die verstedelike landskap te ondersoek en aan te spreek tot voordeel van die bouomgewing. Die ontwerp poog om die huidige negatiewe element van water eerder te bewaar en die gebruik daarvan te aan te moedig. Hierdeur word word die omswaai in sosiale, ekonomiese en ekologiese faktore inplekgestel. ‘n Projek sal dan terselfdertyd as verstedelike genereerder dien. ‘n Innoverende oplossing, ‘n stedelike water park, is geondersoek en getoets. Hierdie sal moontlik as die oplossing dien van die huidige vloedprobleme in hierdie Afrika stad (Maputo, Mosambiek).
