An examination of the challenges of quality water provision in Madibeng local municipality, North West province

Like most municipalities in South Africa, Madibeng local municipality (MLM) is faced with the dual problem of access to water and provision of quality water services. Despite the constitutional responsibility bestowed on municipalities to ensure that residents have consistent access to affordable, reliable and quality water, communities in larger portions of the MLM still have no access to quality water services. This article aimed to explore challenges of quality water service provision in MLM. Focusing on the Letlhabile area within the MLM, the article applied a mixed-method research approach whereby a non-probability sampling design was used to draw a sample of 70 respondents, comprising residents and responsible municipal officials. As part of the study findings, several challenges hindering provision of water services in MLM were confirmed. These included faltering district-local relations between MLM and Bojanala Platinum District Municipality, acute scarcity of technical skills such as water treatment technicians and as paucity of competent municipal leadership. In its conclusion, this article proposes possible solutions to the water-related problems prevalent in the municipality.

Ekofeminist Tartışmalar Bağlamında Su Tüketimi ve Cinsiyet Kimliği Arasındaki İlişki Üzerine Bir İnceleme

Water is a natural resource that interrelated with gender identity. Women need more water because of gender-based roles, they are more open to water-related problems, and gender-based differences in sustainable use of water are some of these dimensions. In this study, the dimensions of the relationship between gender identity and water consumption were examined. The study area is Bahcelievler district, which has the highest population and water consumption amount in Balikesir city for 2018. 10 women and 10 men, who work or reside in Bahcelievler neighborhood, were interviewed based on a semi-structured interview form. Interview texts were analyzed by discourse analysis. The study concluded that women are positioned as “consumers” in water consumption because of their gender-based roles. But their consumption related to maintain the reproduction of the family and their water savings are through which these. In this regard, the findings of the study point to the relationship between the secondaryization of women and nature and gender-based differences in sensitivity to nature.

Effective Management of Storm water in Ibeju–Lekki Local Government Area of Lagos State, Nigeria

In recent years, many cities and rural areas are facing frequent waterlogging, run-off pollution, huge loss of resourceful rainwater, damaged ecosystem and many more rain water related problems. In regional perspective, how to construct a sustainable storm water management measures have been presented as an important issue in many cities and urban agglomeration in Nigeria. Ibeju Lekki area is usually faced with the problem of rain water leading to incessant flooding. This study therefore assesses storm water management in Ibeju-Lekki Area, Lagos state. The research employs a random sampling technique in selecting 204 (0.07  ) respondents for questionnaire administration. Descriptive and inferential statistical tools were employed in the analysis of the data. Pearson product moment correlation was used to test the relationship between the gradient analysis and vulnerability to runoff of Ibeju-Lekki. Also, the slope analysis of the study area was carried out using slope calculation. Findings revealed that natural green space, public parks and gardens and drainage system were the most available storm water management infrastructure in the area. The result of correlation analysis with r = 0.971 shows a strong positive correlation between gradient and vulnerability to runoff. The study concluded that physical planning policies such as thorough monitoring of building plan before approval and institution of effective development control agencies among others should be put in place to ensure proper management of storm water in Ibeju-Lekki local government area of Lagos state

Health Risks and Potential Sources of Contamination of Groundwater Used by Public Schools in Vhuronga 1, Limpopo Province, South Africa.

Public schools in most rural areas of South Africa depend on untreated groundwater due to unreliable water supply by the municipalities. This has the potential to cause water-related health problems to school children. Temperature, pH, and electrical conductivity (EC) were measured in situ. Chemical (fluoride, chloride, sulphate, phosphate, nitrate, magnesium, calcium, sodium, and potassium) and microbial (Escherichia coliform (E. coli), Salmonella typhimurium, and Shigella flexneri) water quality parameters were analysed in groundwater samples from 10 public schools in Vhuronga 1 to determine suitability for use. Quantitative microbial risk assessment was carried out to determine risks of infection and illness due to consumption of groundwater. Correlation analysis was used to identify potential sources of contamination. All physical and most chemical water quality parameters were within guidelines for domestic water use. A high proportion of schools had high levels of microbial organisms. Risks of infection per day were relatively low for all schools. The annual risks of infection due to E. coli and Shigella flexneri for most schools was high, with maximum values of 89.11 and 83.75%, respectively. Maximum risks of illness per year were 31.19, 30.37, and 29.31% for E. coli, Salmonella typhimurium, and Shigella flexneri, respectively. Correlation analysis indicated potential contamination of groundwater by agricultural activities, domestic waste, and faecal contamination from pit latrines. Preventive and mitigation measures to minimise such risks, including locating boreholes at safe distances from pit latrines, prevention/minimisation of pollution of groundwater from agricultural activities, and point-of-use treatment of groundwater by the schools are therefore essential.

As a result, Indonesia including Bengkulu experiences regular natural disasters. Stable isotopes ( δ 18 O and δ 2 H ) have been used as natural tracers in solving water resources and water-related problems. The aim of this research is to investigate the variations of stable isotopes in Bengkulu City from three locations, namely Serut and Hitam Rivers and the Universitas Bengkulu (UNIB) lake, and to understand the hydrological processes in Bengkulu City. In this research, samples of surface water from Serut and Hitam Rivers and UNIB Lake in Bengkulu City were collected over five months between December 2018 and April 2019. Stable isotope compositions of these water samples were examined to understand the local hydrological processes. The result shows that the water samples are generally situated at the right side of Local Meteoric Water Line (LMWL) in δ 18 O and δ 2 H plot, indicating that water samples are more enriched in 18 O and 2 H as compared with the rainwater due to fractionation processes. The surface water samples define a local evaporation line with a slope of 6.536 while the LMWL has a slope of 7.848. This result indicates a significant evaporation effect on water bodies. Moreover, the slope of the regression line in all water samples was lower than the LMWL, in order of Serut River (7.696) > Hitam River (6.851) > UNIB Lake (6.436), indicating that UNIB Lake experienced more significant evaporation than river waters, resulting in enrichment in heavy isotopes. Serut River, one of largest river in Bengkulu City, which also plays an important role in flooding in Bengkulu City, has a regression equation similar to the regression line of rainwater (LMWL). It may be indicated that surface water from Serut River is strongly influenced by rainwater. Consequently, high amount of rainfall can affect the water level of Serut River, and can be associated with flooding. Therefore, long-term monitoring of stable isotopes is very important in the future to provide the pattern of changes in isotopic variation, particularly during flood and drought events as climate-disaster mitigation effort.

Special Issue “Public Policy Analysis of Integrated Water Resource Management”

Public policy analysis is interested in how policies emerge and develop in order to address societal problems. Issues related to water, such as the contamination of surface waters, floods, or plastic pollution in oceans are often highly complex, concern different jurisdictions, and require the collaboration of public and private actors. This complexity is addressed through integrated water management principles. However, these principles give room to open questions such as: what are the main challenges of policy analysis (research and practice) in terms of multi-level actor involvement (politics), cross-sectoral solutions (policies), and new institutional arrangements (polity)? To answer these questions, the seven papers of this Special Issue combine approaches borrowed from policy analysis with principles of Integrated Water Resources Management (IWRM). Each article tackles a complex, water-related problem and collectively, the papers present empirical evidence from case studies located around the world. We learn from all these analyses that adopting a policy perspective helps disentangling the procedural components of IWRM (the involvement of actors, the definition of the appropriate management area, the attribution of competences, etc.) from more substantial ones (like the development of a management plan and the implementation of measures). Addressing cross-sectoral and multi-level challenges is a difficult task, and policy analysis can help shedding light on both, the legitimacy of processes, and the effectiveness of their outputs and outcomes.

Analysis of Rainfall Runoff Pollution and Pollution Load Estimation for Urban Communities in a Highly Urbanized Region

The Taihu Lake plain is a highly urbanized region in China with many water-related environmental problems. Although point-source pollution has been effectively controlled by government legislation, urban surface runoff pollution is still a major issue. Different types of urban communities were selected for rainfall runoff experiments. According to the monitoring data of rainfall events, multiple methods were used to analyze the characteristics of surface runoff pollution and estimate the pollution load for different types of communities. The results indicated that surface runoff from urban communities reduced the river water quality. Certain degrees of the 'first flush' effect occurred in different types of urban communities. The surface runoff pollution in the commercial residential community was weaker than that in commercial and private residential communities; however, the first flush occurred more frequently in the commercial residential community. Holding back 30% of the surface runoff could effectively improve the runoff water quality in commercial and private residential communities as well as the commercial residential community with restaurants. In the commercial residential community, 25% of surface runoff should be held to improve runoff water quality effectively. The loads of pollutants, especially nitrogen and phosphorus, in urban communities in the Taihu Lake basin were higher than those in other regions in China. This research can assist with the reduction of surface runoff pollution in highly urbanized communities.

A study on water's green economy for development in agriculture

The concept of a green economy has gained currency in recent years as a paradigm for promoting economic growth and increased well-being while protecting the environment and contributing to poverty alleviation. There is no common definition of green economy, but the term clearly emphasizes the economic dimension of sustainability. Not only do the environmental (stewardship) and economic (growth) dimensions coexist in the green economy, but they are also complementary and mutually reinforcing strategies to achieve development. Water scarcity, pollution, and other water related environmental and ecological problems have been increasing rapidly in many areas of the world. Water demand management or making better use of the water we have as opposed to augmenting supply is increasingly proposed as a way of mitigating water scarcity problems. Although the achievements of irrigation in ensuring food security and improving rural welfare have been impressive, past experience also indicates problems and failures of irrigated agriculture. In addition to large water use and low efficiency, environmental concerns are usually considered the most significant problem of the irrigation sector. Environmental problems include excessive water depletion, water quality reduction, water logging and salinization. In some basins (water resources), excessive diversion of river water for irrigation (and other uses) has brought environmental and ecological disasters to downstream areas, and groundwater pumping at unsustainable rates has contributed to the lowering of groundwater tables and to salt water intrusion in some coastal areas. Many water quality problems have also been created or aggravated by changes in stream flows associated with agriculture’s consumptive uses. Moving water away from agriculture to uses with higher economic value is one of the main measures widely seen as desirable. This apparent misallocation is often attributed to the failure of government to allocate water rationally. This paper focuses on achieving a sustainable balance between irrigation management and sustainable development and water investments.

Effect of barium and strontium ions on the morphology and polymorphism of CaCO3

Industrial internal water treatment programs provide a robust solution for many water related problems such as scale inhibition, corrosion control, microbial growth etc. in heat transfer equipment. In order to design a good program it is essential to study the individual effect of each constituent in the program and how it affect the parameters for which it is added. Ethylenediaminetetraacetic acid (EDTA) is one such constituent widely used in internal treatment for scale inhibition. Calcium carbonate (CaCO3) is one of the major constituents in scale. Polymorphism and morphology of the crystallites have significant effect on the nature of scale. In this work, we report the effect of EDTA on the morphology and polymorphic composition of CaCO3 in the presence of barium and strontium ions and their effect on the scale inhibition.

IMPACT OF CLIMATIC PARAMETERS ON CROP WATER REQUIREMENTS IN DIFFERENT AGRO ECOLOGICAL ZONES OF PAKISTAN

The problem of climate change has become very strongly during last two decades on global scale in view of the projected consequences on the environment of unguarded states. Gradually rising temperature and its effects on the crops here and rainfall are obvious in many areas around the world. Climate change related to natural and anthropogenic processes in Pakistan is the major source of study in this report. The impacts of these climate changes appear to be additional component of the large number of existing water related problems in every station of Pakistan. The objective of this report is to analyze the global warming effect on CWR. For this purpose, we made seven scenarios So, S1, S2, S3, S4, S5 and S6. From So-S3 crop water requirement increases in all regions but from S4-S6 crop water requirement remains same. For this purpose we selected different cities from agro ecological stations to check the effect of climate change on CWR. Faisalabad, Gupis, Jacobabad, Kalat, Karachi, Multan, Nawabshah, Peshawar and Zhob are the regions selected for this research. Different scenarios have been made such that, in So scenario temperature remains same but from S1, S2 and S3 scenarios temperature is increases 1, 2 and 3 degree centigrade respectively. While, in S4, S5 and S6 scenarios precipitation increases or decreases according to the climatic changes of that area (So, S1, S2, S3, ) and then we increase or decrease the precipitation rate by 5%, 10% and 15% (S4, S5, S6) in accordance with the zone. From result it is concluded that the crop water requirement in arid and in semi-arid is increasing annually on the other hand the total value of effective rainfall in Pakistan is decreasing.

Isolation and identification of microorganisms from water samples in rivers state university of science and technology tanks

Safe drinking water is vital for the survival of humans and other living organisms that depend on it, but when pathogens are present, it limits the use of the water. The microorganisms present in Rivers State University of Science and Technology hostels water tanks were isolated and identified; and the effects of the microbes were determined. Six (6) water samples gotten from different tanks were analysed for their microbiological quality for a period of three (3) weeks. Fungal colonies were isolated using the wet mount technique on commercially prepared Potato dextrose agar (PDA), the multiple tube fermentation technique with MacConkey broth and Nutrient agar were used as media for the isolation and identification of the bacterial colonies. From the analysis, the bacterial count was higher than the fungal count. This indicates faecal contamination ranging between 5 x 100 to 2.6 x 101 coliform (MPN) per 100ml. Also, the total heterotrophic bacterial count ranged from 4.05 x 106 to 1.14 x 107 with the fungal count being the lowest by having 7.0 x 104 to 1.8 x 105. The microorganisms isolated from the water tank samples were Aspergillus species, Penicillium species, Rhizopus species, Mucor species, Escherichia species, Enterobacter species, Bacillus species, Pseudomonas species and Klebsiella species. Klebsiella species which are high across all samples have been known to cause destructive pneumonia. The occurrence of these pathogenic bacteria in drinking water may increase the risks of water-related diseases and health problems to the susceptible residents

Assessment of wheat\u2019s water footprint and virtual water trade: a case study for Turkey

BackgroundMany countries are experiencing significant water scarcity and related problems due to limited availability, uneven distribution of water resources and high demand. Therefore, increasing water use efficiency and better management of existing resources have become substantially important. The agricultural sector is responsible for around 80% of global freshwater withdrawal. Wheat is one of the most important crops having large volumes of virtual water (VW) which is defined as the hidden water embedded in the products.MethodsWater footprint (WF) is an indicator showing the total volume of freshwater consumption of a product or process. Blue water concept is defined as the amount of exploited surface and groundwater resources. Green water represents the total volume of rainwater allocated by the product. WF methodology brings a new approach to inter-regional water use and management by quantifying the amount of direct and indirect water use and tracing the hidden links between production, consumption and trade. The main objective of this study is to analyze Turkey’s national blue and green WF of wheat production, consumption and virtual water trade between 2008 and 2019. Detailed province-based quantification of wheat’s water exploitation is provided using spatial interpolation method.ResultsTotal consumptive WF of wheat production and consumption of Turkey is calculated as 39.3 and 48.1 Gm3/year, respectively. The average blue and green VW contents of wheat production through Turkey are assessed to be 1161 and 748 m3/ton, respectively. The water footprint parameters of each province are calculated and discussed using climatic and agricultural data. VW transfer of Turkey’s international wheat trade is also analyzed. Total national water saving is calculated as 7.8 Gm3/year which is mostly imported from Russia. Global VW deficit due to international wheat trade is calculated to be 1.76 Gm3/year.ConclusionDespite its high contribution to global wheat production, increasing population and strong wheat-based diet, quantitative, comparative and up-to-date analyses of the blue and green WF and the VW transfer of wheat production in Turkey are not available. This study contributes to the national and international water management and planning studies to increase the water allocation efficiency of agricultural products.

The Water Status in China and an Adaptive Governance Frame for Water Management.

China is increasingly facing water-related problems, such as water scarcity, pollution, and overexploitation of groundwater. This paper discusses the water status in China and claims that governance is the cause of water-related problems. The structure of the current water management is analyzed to conclude that the control-command is a static approach which is less capable of dealing with the uncertainty in the water resources system. An adaptive governance frame is introduced, which highlights the learning process and participation. The learning process avoids making the same mistake twice and the participation ensures the diversity of information, which are both necessary for water resources management.

Analysis of Current and Future WaterYejube is one of the rapidly developing towns in Ethiopia. Difficulties of acceptable water supplies and reduction of non-revenue water remains one of the main challenges facing Demand Scenario in Yejube Town, Ethiopia

Yejube is one of the rapidly developing towns in Ethiopia. Difficulties of acceptable water supplies and reduction of non-revenue water remains one of the main challenges facing Yejube water supply system. This study is concentration on the analysis of water demand scenario and future water demand forecasting of for Yejube town. A mixed cross-sectional research method was implemented to analyzed the past and future water demand of the town. The outcome of this study found that the municipal average daily water consumption per capita was 14.3l/c/day and 16l/c/day respectively in 2017 and 2018. The water supply coverage of the town is low when we compare the regional and international standards. Water production and demand are unbalanced, due to continuous interruption of the water supply system inhabitants are facing water related problems. And also, 20.38% and 24% of the water production lost in the distribution system before reaching to the end customers. The population of the town in 2040 expected to reach 24807 with an average daily per capita water consumption of 36.7l/day. Generally, delivery of hygienic Water Supply is one of the key influencing factors that significantly subsidize to the socioeconomic renovation of a country by enlightening the health thereby increasing life standard and economic productivity of the society. Therefore, accurate forecast of future water demand plays a crucial role in optimizing the need for potable water resources and effective water allocation among competing users.

An Engineering Perspective of Water Sharing Issues in Pakistan

Water sharing within the states/provinces of a country and cross-border is unavoidable. Conflicts between the sharing entities might turn more severe due to additional dependency on water, growing population, and reduced availability as a result of climate change at many locations. Pakistan, being an agricultural country, is severely water stressed and heading toward a worsening situation in the near future. Pakistan is heading toward water scarcity as water availability in the Indus basin is becoming critical. Being a downstream riparian of India and Afghanistan in the Indus basin, water availability depends on the releases of water from both countries. The Indus Water Treaty is governing the water distribution rights between India and Pakistan. However, there exists no proper agreement between Pakistan and Afghanistan and the construction of new dams on the Kabul River is another threat to water availability to Pakistan. Correct implementation of the Indus Water Treaty with India is required, together with an effective agreement with Afghanistan about the water sharing. In addition to water shortage, poor management of water resources, inequitable sharing of water, lack of a systematic approach, old-fashioned irrigation practices, and growing agricultural products with large water footprints are all exacerbating the problem. The water shortage is now increasingly countered by the use of groundwater. This sudden high extraction of groundwater is causing depletion of the groundwater table and groundwater quality issues. This water shortage is exacerbating the provincial conflicts over water, such as those between Punjab and Sindh provinces. At one end, a uniform nationwide water allocation policy is required. At the same time, modern irrigation techniques and low-water-footprint agricultural products should be promoted. A fair water-pricing mechanism of surface water and groundwater could be an effective measure, whereas a strict policy on groundwater usage is equally important. Political will and determination to address the water issues are required. The solutions must be based on transparency and equity, by using engineering approaches, combined with comprehensive social support. To develop a comprehensive water strategy, a dedicated technopolitical institute to strengthen the capabilities of nationwide expertise and address the issues on a regular basis is required to overcome the complex and multidimensional water-related problems of the country.

Evolutionary algorithms (EAs) have become competitive solvers of a wide variety of water-resources optimization problems. Genetic programming (GP) has become a leading EA since its inception in 1985. This paper reviews the state-of-the-art of GP and its applications in water-resources systems analysis. A comprehensive knowledge about GP's theory and modeling approach is essential for its successful application in water-resources systems analysis. This review presents variants of GP that have been proven useful in various applications to water resources problems. Several examples of applications of GP in water-resources systems analysis are herein presented. This review reveals GP's capability and superiority compared to other conventional methods, which makes it suitable for solving a wide variety of water-related problems including rainfall-runoff modeling, streamflow sediment prediction, flood prediction and routing, evaporation and evapotranspiration forecasting, reservoir operation, groundwater modeling, water quality modeling, water demand forecasting, and water distribution systems.

Sustainable product design through water themes: a case study of concepts of the Japan Design Foundation

Toward the lack of academic studies from designers' viewpoint on issues of natural resources water, this preliminary paper in a series of chronological studies reviews the concepts based on the water theme from the design competition by Japan Design Foundation. The designers' perceptions of the water theme are studied from social, cultural, and environmental perspectives. According to the results, designers showed strong skills in solving water-related problems, such as conservation and protection. They also offered innovative solutions and unique ideas based on such strategies as the innovative use of natural water resources and material selection. An original design concept system was identified - a hybrid of equipment - that explored on a large-scale the sustainable resources of the sea. The main findings of this research led to a proposed concept mapping of the water theme, and its practicality was illustrated through a case study entitled Mobile Greenhouse Farm System.

MITIGATING DRINKING WATER CRISIS IN TAMIL NADU

India is the fifth largest country in terms of area in the world. It has 3.288 million sq. km. The first four largest countries are: Russia (17.075 m.sq.km); the USA (9.629 m.sq.km); China (9.597 m.sq.km); and Brazil (8.512 m.sq.km). Population wise, India ranks second in the world. As on 18.08.2019 India’s population is 1365.3 million and World population is 7676.6 million (indiastat.com). That is, India has 17.8% of the world population. As far as Tamil Nadu is concerned, its population in 2011 was 72.14 million and it increased to 81.20 million in 2019. As far as the world water resources is concerned, the 29% of land area has one lakh KM3 of fresh water, in which about 60% goes as evaporation annually. The remaining 40%, i.e. 40,000 KM3 goes as run-off by rivers and percolation to groundwater in the world. India’s share is 4% of world supply that is 4000 KM3. It is estimated in India, 51% of precipitation goes as evaporation and the remaining 49% is the annual water resources that is 1953 KM3. This is divided as 1521 KM3 (78%) as surface water and 432 KM3 (22%) as groundwater resource. From this quantum, the annual utilizable water is calculated as 1086 KM3 (690 KM3 as surface water and 396 KM3 as groundwater). However, the present quantity of water use is only 600 KM3 from both surface and groundwater resources. This is only 31% of annual water resources (for details see chart 1). If, available quantity is prudently used India can solve many water related problems.

Exploring the meanings that stakeholders of the Brandfort community ascribe to their experiences of a Dalcroze-inspired workshop

For some time now, urban settlements in the rural areas of South Africa have experienced considerable problems relating to municipal water and sanitation service delivery. In September 2013, as part of a larger investigation in the town of Brandfort in the Free State Province, a transdisciplinary research team, Cultural Dynamics of Water (CuDyWat), conducted a workshop using Dalcroze-inspired activities based on music and movement to generate insight into local water-related problems. The objective was to come to an understanding of the lived experiences of a random group of community members and to contemplate potential solutions to the conundrum. This article reports on a novel application of Dalcroze, with non-musician participants, for the betterment of a social group in crisis. It is argued that Dalcroze-inspired activities are useful to encourage people to express themselves and gain better insight into the problems they face. This approach also serves to strengthen relationships in highly diverse groups.

Mapping evapotranspiration variability over a complex oasis-desert ecosystem based on automated calibration of Landsat 7 ETM+ data in SEBAL

Fragmented ecosystems of the desiccated Aral Sea seek answers to the profound local hydrologically- and water-related problems. Particularly, in the Small Aral Sea Basin (SASB), these problems are associated with low precipitation, increased temperature, land use and evapotranspiration (ET) changes. Here, the utility of high-resolution satellite dataset is employed to model the growing season dynamic of near-surface fluxes controlled by the advective effects of desert and oasis ecosystems in the SASB. This study adapted and applied the sensible heat flux calibration mechanism of Surface Energy Balance Algorithm for Land (SEBAL) to 16 clear-sky Landsat 7 ETM+ dataset, following a guided automatic pixels search from surface temperature Ts and Normalized Difference Vegetation Index NDVI ( ). Results were comprehensively validated with flux components and actual ET (ETa) outputs of Eddy Covariance (EC) and Meteorological Station (KZL) observations located in the desert and oasis, respectively. Compared with the original SEBAL, a noteworthy enhancement of flux estimations was achieved as follows: – desert ecosystem ETa R2 = 0.94; oasis ecosystem ETa R2 = 0.98 (P < 0.05). The improvement uncovered the exact land use contributions to ETa variability, with average estimates ranging from 1.24 mm to 6.98 mm . Additionally, instantaneous ET to NDVI (ETins-NDVI) ratio indicated that desert and oasis consumptive water use vary significantly with time of the season. This study indicates the possibility of continuous daily ET monitoring with considerable implications for improving water resources decision support over complex data-scarce drylands.
