School health and nutrition environments: A multicountry survey in five countries of sub-Saharan Africa region-Burkina Faso, Ethiopia, South Africa, Sudan, and Tanzania.

Schools are increasingly regarded as a key setting for promoting the health, well-being, and development of children and adolescents. In this multicountry cross-sectional survey, we describe the health, nutrition, and food environments of public primary schools in five urban settings in Africa region: Ouagadougou, Burkina Faso; Addis Ababa, Ethiopia; Durban; South Africa, Khartoum, Sudan; and, Dar es Salaam, Tanzania. We evaluated the school health and nutrition (SHN) environments in three main areas: (1) the availability of health-related policies, guidelines, and school curricula, (2) the provision of health, nutrition, and water, sanitation, and hygiene (WASH)services in schools, and (3) the school food environments and eating habits of adolescents. We used stratified random sampling to recruit 79 schools from five countries. Trained fieldworkers collected standardized questionnaire data from 79 school administrators, 765 food vendors, and 4999 in-school adolescents aged 10-15 years. In our study, 24 out of 79 school administrators were aware of their school's health-related policies and guidelines while 30 schools had a specific SHN curriculum. In general, health, nutrition, and WASH services were inadequate. Possibly due to a lack of school kitchens, 14.4% of students bought snacks and unhealthy foods from food vendors. Our study indicates that schools' food and nutrition environments are insufficient to improve adolescent health and nutrition in the African region, including limited coverage of SHN policies, suboptimal facilities and nutrition services, and unregulated food environments. Schools in sub-Saharan Africa need to improve their health and nutrition environments.

Consideration of water policies in the urban development plans of Delhi: A collaborative planning perspective

AbstractThis paper discusses collaborative planning principles as a means to improve water supply systems in the case of Delhi, India, through primary and secondary data analysis. The theory of collaborative planning is a well‐established concept applied to obtain effective policies in planning through the collaboration of actors in a shared space. We use this framework to discuss strengths, weaknesses, and scope for collaboration in the current urban development plan formulation process of the city. Some of the principles of collaborative planning we use include communication, collective decision‐making processes, and network power in a shared institutional environment. Our findings indicate a lack of consideration of water policies in the urban development plans. This underlines a major gap in the current process of plan formulation and provides evidence that the absence of collaboration between institutions in both sectors contributes to poor water supply for the population in Delhi. At the same time, it emphasizes the importance of collaborative practices between urban development and water institutions for better planning of water service provision in Indian cities.

Transformations in the sanitation sector in the State of Rio de Janeiro: neoliberalism and regulatory changes

This article analyzes the reconfiguration of water supply services provided to municipalities across the State of Rio de Janeiro. It seeks to examines how advancements in the neoliberalization of Brazil's basic sanitation sector have contributed to a fragmentation in the provision of services and to the emergence of uneven geographies on a regional scale. This will be conducted through the lens of policy experimentation, particularly after the approval of Law 14.026/2020. The study is based on an approach concerning the commodification of public services within the context of neoliberalism, marked by a complex reformulation of regulatory mechanisms. The methodology combines an analysis of secondary data, documentary research, and thematic mapping. The results reveal that the management of sanitation services is increasingly guided by market logic, with the experimentation of controversial regulatory mechanisms that have exacerbated fragmentation and deepened territorial inequality.

The governance of the water-energy nexus: Co-produced narratives to take stock and address energy dependencies of the urban water cycle in Atlantic Europe

Water and energy (WE) are key resources to support human well-being and are highly interconnected. Intensifying demands of both resources and increasing resource scarcity are exacerbating their interconnectedness and calling for the adoption of an integrated approach called “WE nexus”. This paper explores the barriers and opportunities to govern the WE nexus in the Urban Water Cycle (UWC), particularly, the energy dependencies of the water supply and sanitation services in Atlantic Europe, through the assessment of four contrasting and representative regions: Canary Islands (ES), Western Andalusia (ES), Alentejo (PT) and Brittany (FR). We applied a “Quantitative Story Telling (QST)” method to assess the discourses from 49 stakeholders from across the four regions on WE nexus challenges and opportunities in the UWC, and the evidence that exists on them. The result is a pluralistic narrative incorporating the views of different stakeholders on what are the issues at stake and why, what needs to be done and how, and sustained by available data. The resulting narrative explores the formal aspects underpinning WE nexus governance in the UWC, but also informal rules linked to political economy. Our results revealed that WE nexus challenges are context-specific, however, there are important commonalities across regions and phases of the UWC value chain, suggesting that these are relevant at the Atlantic Europe scale. QST is not instrumental in directly inducing policy change or decision-making, but might be a valuable means for knowledge mobilization to question and enrich the quality of dominant discourses, and thus paving the road for action towards sustainability.

Abiotic Factors and The Growth of Cyanobacteria in Surface Water Reservoirs in The State of Pernambuco

Objective: Analyze the relationship between physical-chemical and climatic abiotic factors in relation to the occurrence of cyanobacteria genera in surface water reservoirs used for public supply in the state of Pernambuco. Literature Review: Information is presented on cyanobacteria and the consequences of the release of untreated effluents on the eutrophication of surface waters with effects on the growth of cyanobacteria and consequences for aquatic organisms and humans and the climate in regions of Pernambuco where water reservoirs are located. Method: Quali-quantitative descriptive and exploratory approach to the analysis of abiotic variables (pH, C.E., Turbidity, Color, Calcium, Magnesium, Chlorides, Sulfate, Nitrogen, Phosphate, Alkalinity, Hardness, Iron, Manganese, Aluminum and rainfall) and biotic (Cyanobacteria density), collected from the Pernambuco Sanitation Company – COMPESA. The samples were from eutrophic freshwater reservoirs in Pernambuco collected between 2010 and 2020. Results and Discussion: The most frequent genus of cyanobacteria was Raphidiopsis/Cylindrospermopsis, found abundantly in all reservoirs, where the increase in color, turbidity and pH were positively correlated with the presence of Microcystis and Raphidiopsis/Cylindrospermopsis, and negatively with the increase in toughness. A positive correlation was also observed between hardness and the increase in Planktothrix density. Research Implications: Generate guidelines for drinking water supply services, presenting tools for understanding abiotic conditions that influence the growth of cyanobacteria, in order to outline control or mitigation strategies in ETAs. Originality/Value: Generate useful information in the evaluation of abiotic parameters and cyanobacteria density, observed over a long period (10 years), showing positive/negative correlations in surface waters used for human consumption.

Self-help and spontaneous heroism in urban service delivery in Ghana’s informal neighbourhoods: a case study of Moshie Zongo

ABSTRACT The delivery of urban services and facilities is the primary responsibility of both local and central governments to facilitate the day-to-day activities of urban dwellers. However, the financial incapacity, coupled with general institutional constraints, hinders the efficient and adequate provision of all relevant infrastructure facilities needed by urban dwellers, particularly, in informal neighbourhoods. In response, self-help initiatives and spontaneous activities of some actors have emerged to bridge the gap and at best, complement the government’s development efforts. Utilising a mixed-method approach, the study relied on both quantitative and qualitative data from 374 randomly selected households as well as key informants from relevant institutions to explore the dynamism of self-help initiatives. The study specifically relies on the delivery of waste management and water supply services to evaluate and understand self-help initiatives in Moshie Zongo, an informal community in Kumasi City. From the analysis, the tricycle waste collectors (Aboboya) through the self-help initiative collect about 80%−90% of the solid waste generated in the area which is also preferred by about 80% of the community dwellers. Moreover, about 60% of the sources of water are owned by private individuals. Again, the Wastes Department of KMA, through Build Operate and Transfer (BOT) and Renovate, Operate, and Transfer (ROT) has helped to provide and renovate new and existing toilet facilities to ensure the provision and management of liquid waste in informal settlements. The study proposes effective and efficient monitoring, coordination, and regulation to enhance this initiative in the delivery of urban infrastructure and services.

Spatiotemporal Coupling Analysis of Urbanization and Ecosystem Services in Southeastern Fujian

Revealing the spatiotemporal coupling relationship between urbanization and ecosystem services can help to clarify regional development differences, optimize the implementation path of urbanization, and improve the quality of ecosystem services. Taking southeastern Fujian, a region with a good ecological foundation and strong urbanization potential, as a case study, the levels of multidimensional urbanization systems and typical ecosystem services of this region in the years 2000, 2010, and 2020 were quantified using the index comprehensive evaluation method and the InVEST model. The Pearson correlation coefficient and the coupling coordination degree model were used to analyze the spatiotemporal coupling relationship between urbanization and ecosystem services, and suggestions for improving regional coordinated development were proposed. The results showed that： ① The comprehensive urbanization level in southeastern Fujian increased continuously, with an average annual growth rate of 7.3%, of which social urbanization was the fastest, followed by economic urbanization and population urbanization, and spatial urbanization was relatively backward. Ecosystem services tended to decline, especially food and water provision services, which decreased by 61.9% and 46.9%, respectively. The spatial distribution showed a mismatch pattern of "high urbanization level and weak ecosystem services" in the southeast coastal area and "low urbanization level and strong ecosystem services" in the northwest inland area. ② The correlation between urbanization and ecosystem services was mainly negative. The negative effect of economic and social urbanization on ecosystem services was weaker than that of population and spatial urbanization, with a clear weakening tendency. As population and spatial urbanization slowed down sharply and economic and social urbanization accelerated, the driving force of urbanization development gradually shifted from "quantitative increase" to "qualitative improvement." Thus, the decline of ecosystem services was alleviated. ③ Comprehensive urbanization and various ecosystem services experienced three stages of "imbalance-transition-reconciliation," with an average increase of 60.5% to 120.6% in the coupling coordination degree. However, highly coordinated regions remained scarce, indicating that there is still significant room for improvement. The relative relationship between urbanization and ecosystem services evolved from urbanization lag to ecosystem services lag. The fluctuation problem of backward coupling coordination level caused by excessive urbanization had initially appeared in the southeastern coastal area. Therefore, in future construction, southeastern Fujian should improve economic quality and social benefits； strengthen the overall management, protection, and restoration of ecological space； and enhance the order and stability of the coordinated development of urbanization and ecosystem services.

Impact of fire exclusion and aspect on soil carbon fractions in Afromontane grasslands, Cathedral Peak, South Africa

AbstractDespite the importance of South Africa's Afromontane grasslands for ecosystem services (water supply and biodiversity), soil organic carbon (SOC) research remains limited. These grasslands evolved with fire, and fire exclusion leads to native plant afforestation. This study investigated SOC fractions and origin to understand the impact of fire‐exclusion‐driven afforestation and aspect on SOC storage in Afromontane grasslands. This study in Cathedral Peak Research Catchments, initiated in the 1940s, compared an afforested fire‐excluded site (AF) to a periodically burnt (accidental fires, 2–5 years interval) grassland (PB) within the same catchment (Catchment‐IX). Additionally, it compared a south‐facing periodically burnt grassland (Catchment‐IX) to a north‐facing biennially burnt grassland (Catchment‐VI). Soil samples collected at soil‐depth increments (0–5, 5–10, 10–15, 15–20, 20–30, 30–60 and 60–100 cm) revealed that, within Catchment IX, PB had more topsoil SOC stocks and microbial activity than AF but similar active carbon (C) concentrations. As expected, δ13C values revealed that SOC in PB originates from C4 grasses, whilst it mostly originates from C3 plants in AF. The south‐facing slope (Catchment‐IX) had more SOC stocks, microbial activity and active C compared to the north‐facing slope (Catchment‐VI). Fire‐exclusion‐driven afforestation changed SOC input from roots to litter, thus reducing SOC storage. Cooler south‐facing slopes are better C reservoirs. Afromontane grasslands show greater potential for C sequestration than afforested systems.

Who Gets Water? Governance Failures & Persistent Drinking Water and Sanitation Issues

he sustainable provision of potable water and sanitation services presents a multitude of fundamental challenges concerning access and allocation. These challenges extend beyond water resources themselves, encompassing the allocation of rights, responsibilities, and associated risks. Disparities in water supply and sanitation services are stark, both geographically and socioeconomically. A thorough analysis requires examining the international governance instruments that guide access, the property rights frameworks that dictate allocation, and the scales at which these rights and frameworks operate. Additionally, the responsibilities vested in various authorities and stakeholders must be scrutinized. Water insecurity, particularly with respect to drinking water and sanitation, is not solely attributable to natural phenomena. This paper presents a literature review (2008-2023) encompassing research from the Earth Systems Governance community and beyond, focusing on water supply services and sanitation. Access and allocation were interpreted broadly, encompassing issues of inclusive development, justice, sustainability, and additional themes identified through the review process. The findings suggest a significant role for governments in facilitating access and allocation, with failures in these areas leading to long-term consequences. This will necessitate a holistic approach that considers water access and allocation alongside interconnected issues like sanitation, development, climate change, energy, and food security, all within a multi-level governance framework.

Unpacking water governance dynamics and its implications for household water security in post-disaster resettlement communities in the Philippines

Water security is important globally for sustaining households, communities, and the environment. However, most studies have focused on water availability and accessibility, whereas research examining the role of power and politics in shaping water insecurity remains marginal. This study contributes to this research gap by unpacking the overlapping drivers and politics in water governance dynamics that co-produce the water insecurity of Typhoon Haiyan disaster-displaced households in resettlement villages in the Philippines. Using political ecology and water governance perspectives, we ask, What does household water insecurity look like in post-disaster resettlement villages in the Philippines? What are its drivers and how do politics and governance dynamics impact the provision of water services to these villages? Our findings suggest five overlapping drivers: the haphazard relocation of internally displaced persons to areas without access to basic facilities like water; the institutional disharmony and late involvement of water institutions in the resettlement processes; the influence of governance regime in the rapid but substandard housing development, including water distribution systems; the micropolitics in water district management affecting water projects; and the impact of maladaptive resettlement outcomes on households’ capacity to afford water. Ultimately, this study demonstrates how various drivers, including power relations and contestations in water governance, lead to household water insecurity outcomes. It ends by providing brief policy recommendations to improve institutional arrangements for the better governance of water services to resettlement communities.

Assessing energy efficiency of water services and its drivers: A case study from water companies in England and Wales

Understanding how energy efficient the water services are and what drives inefficiency can greatly assist water utilities in delivering sustainable services. This study employs a neural network (NN) approach to measure the energy efficiency of water services in relation to the volume of drinking water supplied and the number of connected properties. Unlike other non-parametric approaches, NN allows capturing the complex relationships and dependencies between various factors influencing energy efficiency of water companies. An empirical application for English and Welsh water utilities embracing water only companies (WoCs) and water and sewerage companies (WaSCs) over 2008–2020 was conducted. The average energy efficiency score was found to be 0.411, indicating that water utilities could potentially save 0.54 kWh per cubic meter of drinking water supplied. Notably, WaSCs exhibited better energy performance compared to WoCs, with energy efficiency scores of 0.559 and 0.239, respectively. Nevertheless, based on the volume of water delivered, WaSCs could save 0.65 kWh/m3 whereas WoCs potential energy savings are 0.24 kWh/m3. Energy efficiency remained relatively stable across the years, with average values of 0.440, 0.388 and 0.454 for the periods 2008–2010, 2011–2015, and 2016–2020, respectively. The analysis conducted using decision tree methods highlighted the relevance of water treatment quality and the source of raw water as key variables influencing the energy efficiency of water utilities. These findings can be valuable for policymakers, enabling them to gain a deeper understanding of the driving factors behind energy efficiency in water service provision.

Estimation of willingness to pay for improved water supply service: Case of Algerian households

ABSTRACT The purpose of this article is to evaluate the water company in Algeria (ADE) subscribers’ Willingness To Pay (WTP) for a better service offer. This study assessed the WTP for improved drinking water in the department of Souk-Ahras (Algeria), using contingent valuation survey data of 5,342 households, with a response rate of 10.86% (greater than 10% of each municipality's total number of subscribers). Then, Probit and Tobit models were applied to analyze the determinants of WTP. The results show that the majority of respondents (62.84%) testified that they were not satisfied with the quality of the service provided in terms of quantity and quality of the water distributed. This research revealed that the WTP for an improved water supply service was approximately 16.18 Algerian dinar (DZD)/m3 (approximately 0.11 US$/m3) instead of the current tariff (6.3 DZD/m3–0.04 US$ /m3). With this new water tariff, the average water charge for a household is around 1.37% of the average monthly income.

Water and Sanitation Practices and performance of Bomet Water and Sanitation Company in Bomet County, Kenya

Water and sanitation provision practices are established with the intention to enhance performance, provision on clean water and enhanced sanitation services. However, globally, not all Water & Sanitation Companies are able to achieve their core mandate of provision of adequate clean water and sanitation services. All Water and Sanitation Companies adopt water and sanitation practices however the extent to which they affect performance of water and sanitation companies is has attracted divergent views while other scholar found a negative affect others found a positive effect and hence a dilemma exist as to what is the exact effect of water and sanitation practices on the performance of water and sanitation companies. At Bomet Water and Sanitation Company in Bomet County, very few studies exist that have been conducted on the subject matter and yet its performance is not optimal and the hence the reason as to why this study was conducted at the Water and Sanitation Company. The purpose of this study was to determine the effect of water and sanitation practices on performance of Bomet Water and Sanitation Company in Bomet County, Kenya. Specific objectives of the study were to establish how resources influences performance of Bomet Water and Sanitation Company, to find out the extent to which stakeholder engagement effects performance of Bomet Water and Sanitation Company, to determine the effects of governance on the performance of Bomet Water and Sanitation Company and to examine the influence of information communication technology on the performance of Bomet Water and Sanitation Company. Theories adopted were; Resource Based View Theory, Stakeholder Theory, Stewardship Theory, Systems Theory and Balance scorecard Theory. The study adopted a descriptive research design and targeted 170 respondents drawn from commercial, technical and administration department. The sample size was 34 staffs selected using stratified random sampling technique. A pilot study was conducted to test the effectiveness and reliability of the research tool. The study used both primary and secondary data sources. Data was analyzed using quantitative approach which involved the use of descriptive statistics that entailed percentages, frequency, mean and standard deviation. Inferential statistic adopted was regression analysis was used to establish existing relationships between water and sanitation provision practices and performance of Bomet Water and Sanitation Company. Results were as follows; resources had a positive and significant effect on performance of BOMWASCO of (β=-0.229, p < 0.05). Stakeholder engagement had a positive and significant effect on performance of BOMWASCO (β=0.231, p < 0.05). Governance had a positive and significant effect on performance of BOMWASCO (β=0.451, p < 0.05). ICT had a positive and significant effect on performance of BOMWASCO (β=0.343, p < 0.05). The study concluded that resources, stakeholder engagement, governance and ICT have a positive and significant effect on performance of BOMWASCO. The study recommended that physical resources should used sufficiently and correctly to enhance equitable water supply all residents. The community should continue to be engaged in all water supply and solid waste collection practices in the County. BOMWASCO board structure should effectively represent diverse stakeholder interests. Current software solutions should continue being used in a manner that effectively meets organizational needs and requirements. The study recommends further studies should be conducted on Water and sanitation practices and performance of other water and sanitation companies in Kenya.

Area prioritising criteria during phased conversion from intermittent to continuous water supply: The case study of Lusaka Water Supply and Sanitation Company, Zambia

ABSTRACT Conversion from intermittent to continuous water supply is a recommended approach for improving water supply service to communities. The conversion process is complex and requires huge financial and human resources investments. Because such resources are always limited and cannot be adequately provided at once, phased conversion is encouraged. However, there are challenges with this approach in terms of which areas should be prioritized during the conversion process so that the water supply situation for the unconverted areas is not aggravated. This article uses a questionnaire and semi-structured interviews to identify the criteria for prioritising areas to be converted during phased conversion to continuous water supply from a water utility perspective. The Lusaka Water Supply and Sanitation Company is used as a case study. Results show that the financial sustainability of the utility company is the major criterion for selecting an area to be prioritized. In countries like Zambia where tariff structures are such that industries subsidise domestic water consumption and the affluent subsidise water consumed by the poor, prioritising financial sustainability entails giving priority to areas where high revenues are expected. This is synonymous with giving priority to the affluent or the middle-class areas with high densities of water consumers.

A multi-criteria model for measuring the sustainability orientation of Italian water utilities

This article investigates the influence of socioeconomic context and stakeholder pressure on water utilities' sustainability performance and disclosure. The Urban Water Cycle Services (UWCS) framework has been adapted to the Italian context and integrated with a social equity variable, which enhances the framework's ability to account for the distinctive characteristics and mission of water utilities in measuring sustainability performance. The sample comprises 17 Italian utilities providing water services that released a sustainability report in 2021. The results show that the socioeconomic context and stakeholder pressure influence how water utilities align with economic, environmental, and social sustainability goals. Listed multi-utility companies are strongly influenced by private shareholders, pushing them towards financial sustainability, while small public water utilities are more sensitive to the needs of their disadvantaged users, especially in low-income contexts. The findings of the study have interesting theoretical, managerial and policy implications.

Threshold Effects between Ecosystem Services and Natural and Social Drivers in Karst Landscapes

It has been shown that there are thresholds of influence on the response of ecosystem services to their drivers, and the range of drivers that provide high levels of ecosystem services can be delineated through thresholds. However, due to the spatial heterogeneity of landscapes in karst regions, the results of ecosystem service threshold studies in non-karst regions may not be applicable to karst regions. This study explores the threshold effects between ecosystem services in karst landscapes and their natural and social drivers. It is shown that there are nonlinear constraints between them, and different critical thresholds exist for different kinds of ecosystem services. The main thresholds for water supply services include the slope (43.64°) and relief amplitude (331.60 m); for water purification services, they include relief amplitude (147.05 m) and distance to urban land (DTUL) (32.30 km); for soil conservation services, they include the normalized difference vegetation index (NDVI) (0.80) and nighttime light intensity (43.58 nW∙cm−2∙sr−1); the main thresholds for biodiversity maintenance services include population density (1481.06 person∙km−2) and distance to urban land (DTUL) (32.80 km). This enables regional ecological conservation planning based on different threshold ranges corresponding to different ecosystem services to meet the different needs of different decision makers.

Association Between Demographic Characteristics of Users’ and Overall Satisfaction with Water Supply Service

Water constitutes an indispensable resource for various aspects of daily life, encompassing essential needs such as drinking, cooking, sanitation, and irrigation. Beyond household applications, diverse livelihood activities, including livestock management, gardening, crop cultivation, food processing, aquaculture, and fisheries, also rely on water. The assessment of customer satisfaction holds paramount significance in driving performance enhancements for service providers, even within government-owned entities offering critical services like water supply. This research aims to scrutinize the interplay between overall satisfaction with water services and its determinants, including satisfaction with water quality, and various parameters such as water supply hours, tap pressure, supplied water quantity, management responsiveness and communication, and water tariff. Anticipatedly, water supply hours, quantity, and quality are expected to exert a crucial influence on user satisfaction. Although users express a satisfaction level above neutral, it falls short of reaching a fully satisfactory level. Key contributors to user satisfaction involve aspects such as water supply hours, pressure, quantity, and quality, while complaints about water supply yield slightly lower satisfaction. Satisfaction with water service hours, quantity, and quality emerges as a driving force for overall satisfaction. The analysis reveals no significant association between overall satisfaction and demographic variables such as occupation, gender, age, education, and the main income source. However, a noteworthy association exists between satisfaction with water pressure and the water collection method, and a robust link is observed between satisfaction with water quality and respondents' water treatment practices. The provision for complaints is significantly associated with satisfaction regarding management responsiveness and communication. Multiple regression analysis underscores a positive relationship between overall satisfaction with water services and satisfaction with water quality and supply hours, indicating that higher satisfaction with these factors enhances overall satisfaction with water services.

Industrial-Based GSM Water Leakage Detection, Monitoring and Controlling System: A case of North Rift Valley Water Agency in Kenya

The current system for detecting and monitoring water leaks in Kenyan industries is manual and costly. Despite emerging new technological trends, many industries lack automated systems to detect, monitor, and control water leakage due to the high cost of maintenance and installation. This study's objective was to develop an automatic, remote, and real-time detection, monitoring, and, control system for water leaks. The system is made up of two nodes, one at the source and one at the destination or tap. The two nodes are made up of an ESP microcontroller, which is used to control all the connected components. The use of the ESP 32 microcontroller was efficient due to its ability to provide WI-FI. Aside from the solenoid valve, which was used to turn the water flow on or off in the event of leaks, the system also includes the FY-201 water flow sensor, which was used to gauge the amount of water flowing through the pipe. Water leakage is detected when the volume of water passing through the two sensors differs in terms of volume, indicating that a water leakage has just occurred. Thing-Board, an IoT-based platform used to monitor and visualize data from various devices connected, was used for real-time monitoring, visualization, and control. The developed system was tested with different water service providers, and the results showed that the system responds positively to water leakage parameters with capability of monitoring water leakages in a real time.

Appraisal of groundwater quality and hydrochemistry in three regions of Ghana: Implications for drinking purposes

Groundwater is the most relied upon source of water for rural areas and small communities with no access to national water systems. The Community Water and Sanitation Agency (CWSA) in Ghana is an institution that facilitates the provision of water and sanitation services to small towns and communities, hence it has engineered several boreholes all over the country. However, some of these boreholes have quality challenges. Hence this study was carried out to assess the quality and hydrochemical controls of such boreholes in the Ashanti, Upper East and Central Regions of Ghana. A total of 45 boreholes were sampled across these areas and subjected to physicochemical, microbial, and heavy metal analysis. Analysis of the groundwater in the Ashanti Region indicates that its quality is negatively impacted by its iron, manganese, and arsenic content. Same was observed for the Central Region. While in the Upper East Region, total hardness, fluoride, nitrate, and arsenic are the parameters that impact the groundwater quality greatly. Water quality index was used to assess the suitability of the groundwater for domestic purposes and based on this index, 80 % of the water samples were classified as either having an excellent or good quality, while about 7 % were classified as unsuitable for domestic purposes, across all regions. The suitability of the groundwater for irrigational purposes was assessed using sodium adsorption ratio (SAR), percentage sodium (% Na), and Kelly's index (KI). Based on SAR and % Na, all the water samples were suitable for irrigation, while 9 % were unsuitable based on KI. This study provides a comprehensive information on some of the CWSA boreholes with quality challenges. This kind of information is critical and useful when considering what options and treatment technologies would be suitable to address the challenges that these boreholes have.

Impacts of the Covid-19 pandemic on the South African water sector

An analysis of the impacts of the Covid-19 pandemic on the South African water sector is presented. The study identified and focused on three main themes: water revenue collection, water service delivery, and water sector operations. The Covid-19 pandemic negatively impacted these aspects and exacerbated pre-existing problems in the water provision landscape of South Africa. Business continuity management was identified as a top priority for water sector institutions in South Africa to ensure the continued provision of critical water services. In-depth case study research is recommended to establish how water sector institutions in South Africa dealt with the Covid-19 pandemic and how this can inform their disaster preparedness and management going forward.
