The variety of available technologies and the low investment power in sanitation services, especially in regions with low and emerging economies, makes the selection of an optimal wastewater treatment system design an even more complex task for decision-makers. Thus, this study aimed to develop a multi-criteria analysis-based tool to support decision-making on the optimal wastewater treatment technology for the needs and priorities of each region, the Most Appropriate Treatment Technology Index (MATTI). The methodology to apply the MATTI comprises five steps: select suitable technologies; determine the effluent quality parameters; define the most relevant variables for design; normalize and define the weighting criteria; and calculate the level of compliance (0–1, on an increasing scale of suitability). To validate the tool, two different scenarios and seven variables for the Brazilian context were simulated. Different sets of technologies scored above 0.75, and were classified as highly recommended, according to the weight criteria attributed to each scenario. MATTI not only contributed to improving the decision-making process, but also with a more global vision of the parameters to be considered in the selection of technologies to meet the needs and priorities.

The Africa Infrastructure Country Diagnostic (AICD) has produced continent-wide analysis of many aspects of Africa's infrastructure challenge. The main findings were synthesized in a flagship report titled Africa's Infrastructure: a time for transformation, published in November 2009. Meant for policy makers, that report necessarily focused on the high-level conclusions. It attracted widespread media coverage feeding directly into discussions at the 2009 African Union Commission Heads of State Summit on Infrastructure. Although the flagship report served a valuable role in highlighting the main findings of the project, it could not do full justice to the richness of the data collected and technical analysis undertaken. There was clearly a need to make this more detailed material available to a wider audience of infrastructure practitioners. Hence the idea of producing four technical monographs, such as this one, to provide detailed results on each of the major infrastructure sectors, information and communication technologies (ICT), power, transport, and water, as companions to the flagship report. These technical volumes are intended as reference books on each of the infrastructure sectors. They cover all aspects of the AICD project relevant to each sector, including sector performance, gaps in financing and efficiency, and estimates of the need for additional spending on investment, operations, and maintenance. Each volume also comes with a detailed data appendix, providing easy access to all the relevant infrastructure indicators at the country level, which is a resource in and of itself.

Traditionally, infrastructure has been considered an essential component of a country’s development. Therefore, European Union (EU) Member States (MS) invest heavily in this area. A lot of support for infrastructure development is also directed from the EU Structural Funds (SF). However, the results of previous studies do not fully reveal whether the development of infrastructure contributes to EU MS’ economic growth and what factors mediate this effect. Considering the limitations of previous studies, this article aims to examine whether the development of different types of infrastructure (transport, information and communication technologies (ICT), energy, and water and sanitation) contribute to economic growth and to assess whether government quality affects the growth outcomes of infrastructure. Empirical estimations are based on neoclassical specifications and cover 28 EU countries from 2000 to 2019. Estimates revealed that all types of infrastructure positively correlate with growth but not all correlations are significant. Only mobile cellular, which proxies ICT infrastructure, electricity production, which proxies energy infrastructure, and pipeline transport infrastructure significantly affect economic growth. Water and sanitation infrastructure development do not significantly contribute to EU MS’ economic growth. The institutional environment, i.e., less corruption, has a considerable positive effect on the growth outcomes of electricity production and pipeline transport infrastructure.

Urban sanitation in rapidly growing secondary cities remains a critical challenge, particularly in unsewered areas. This study evaluates the effectiveness of open-source data for modelling the sources and movement of faecal matter in such contexts, with a specific focus on Rajshahi, an unsewered secondary city in Bangladesh. By triangulating data from direct observations, key informant interviews (KIIs), and focus group discussions (FGDs), we assess the reliability of using open-source data to map faecal matter flow. The findings demonstrate an 80% alignment between the model’s simulated flow directions and actual field observations, highlighting the potential of using open-source data in urban sanitation management. Furthermore, the study reveals that 80% of buildings are connected to storm drains with many allowing faecal matter to overflow from septic tanks, thus posing a health risk. Despite efforts by the City Corporation to manage the drainage system through reactive measures like drain scraping and unblocking, blocked and overflowing drains remain prevalent, particularly during the rainy season. KIIs and (FGDs) highlight a lack of proactive maintenance and widespread unawareness of sanitation management systems. This integration of field-based insights with open-source data supports for a more proactive, data-driven approach to urban sanitation management in secondary cities, ultimately aiming to enhance public health and quality of life.

Core infrastructure, which covers transportation, information and communication (ICT), energy, water and sanitation systems, plays a significant role in economic growth. The development of core infrastructure – one of the European Union (EU) Cohesion Policy (CP) priorities – is heavily funded. However, it remains unclear whether these investments achieve the main aim, i.e. contribute to economic growth and convergence between EU countries and especially regions. A theoretical model addressing the identified issues is needed to assess the impact of infrastructure on economic growth and convergence comprehensively and as accurately as possible. To reach this aim, first, we have disclosed the definition of infrastructure and its structure. Also, we discussed different approaches to the relationship between infrastructure and economic growth. We developed a theoretical model for evaluating infrastructure impact on economic growth and convergence. Moreover, based on the neoclassical approach, we specified an econometric model that includes indicators of different types of infrastructure and assessed growth and convergence outcomes of infrastructure development. Even though we find that infrastructure positively affects growth and convergence, the estimated impact is not statistically significant except for some types of ICT and transport infrastructure.

Health is considered the most important factor for individual well-being and a country’s sustainable development. Among the influential factors of population health, sanitary infrastructure, particularly sanitary toilets and innocuous-sanitary toilets, have already attracted attention. In recent years, to improve the overall health status of rural residents, the Chinese government has promoted the “toilet revolution” in rural areas to update and modernize the facilities of toilets. Given that migrant workers contribute significantly to China’s economic growth, and that the migrant workers generally lived in rural areas before they moved to urban areas to find jobs, it is of great interest and importance to investigate the impacts of sanitary infrastructure in rural areas on the migrant workers. This study analyzes the spatial characteristic of rural sanitation facilities’ implementation and looks for possible correlation between the health status of migrant workers and the implementation of sanitation facilities in their hometowns. Micro-survey data of migrant workers’ health status from China Household Income Projects (CHIP) 2013 and macro-data of provincial economic factors are matched to provide a quality analysis. The analysis of the spatial distribution shows that there were significantly large gaps between the prevalence rates of sanitary toilets in provinces. Furthermore, the regression analysis indicates that the implementation of sanitary toilets and innocuous-sanitary toilets exhibits a positive effect on the overall health status of migrant workers, although the effects of the innocuous-sanitary toilets are greater. Moreover, the positive influences of both types of toilets on population health are higher in the provinces with relatively greater annual precipitation and higher average temperature.

Cholera is an acute infectious disease caused by two toxin-producing strains, namely Vibrio cholerae O1, and Vibrio cholerae O139. Its recorded history stretches as far back as 1817, in Bengal, India, yet it continues to be a public health threat to this present day. Although cholera epidemics are now a relatively rare phenomenon in developed countries, frequent epidemics continue to be experienced in sub-Saharan Africa. Africa accounted for 63.33% of the 223 370 cases of and 4 159 deaths from cholera that were reported globally in 2020. Furthermore, of the 342 900 cholera cases and 3 304 cholera deaths reported globally in 2022, 40.28% of the cases and 77.85% of the deaths were in Africa. Inadequate sanitation infrastructure as well as inadequate provision of quality, safe drinking water in South Africa still creates conducive conditions for the transmission of cholera. In addition, climate change is increasingly becoming a risk factor towards the spread of V. cholerae pathogens in inland regions. To make recommendations on how South Africa, and potentially the Southern African region as a whole, can minimise the resurgence of cholera, this review addressed the following questions: Does South Africa have adequate sanitation infrastructure to curb the spread of cholera? Is there enough intentional surveillance of environmental water sources for vibrios as a cholera outbreak predictive tool? What is the impact of climate change on the resurgence of cholera in South Africa? And, what needs to be done to curb the resurgence of cholera in South Africa?

This article explores how multiple health risks in municipalities with Roma settlements in Slovakia are related to the varieties of local governance and the authorities’ conduct towards the local Roma population. The first part of the paper describes the situation in Roma settlements from the perspective of unequal access to sewerage and water pipelines. Introduced here are data on identified contagious diseases that correlated multiple health risks with the lack of sanitation and/or water infrastructure. The second section of the paper put forth typologies of government approaches towards the Roma, which based on ethnographic fieldwork, allows us to identify factors of attitudinal, structural and policy-oriented nature. Research results point to a “triad” of key circumstances: these are the structural conditions in municipalities and the history of local inter-ethnic relations and attitude of authorities towards Roma. Finally, possible solutions and approaches regarding how to mitigate the multiple health risks are discussed. It is suggested that on the one hand, in many villages there is a profound institutional discrimination of Roma with respect to water and sanitation infrastructure; on the other hand, water services are increasingly becoming an expensive commodity that not everyone can afford. The article concludes with discussion on enabling conditions and ways to ensure access to basic infrastructure in rural Roma communities. The solution is not only a compliance with principles of non-discrimination and existing technical norms and standards but also in securing the accessible funding for construction of the sanitation infrastructure in a smart way, including innovations and operation of cheaper and environmentally responsible sanitation technologies.

The private sector remains hesitant to invest in water and sanitation infrastructure in Zimbabwe. For policymakers and investors, it is pertinent to understand the factors that determine the signing of water and sanitation public–private partnership (PPP) contracts, in order to leverage expertise and resources to achieve the Sustainable Development Goal targets. This study applied count econometrics on data collected for the 25 years from 1996 ending in 2021, with the aim of investigating the determinants of the number of PPP contracts signed in Zimbabwe. Poisson regression estimations identified positive macroeconomic prospects, financial market development, and strong institutional governance environment as important determinants for PPP contracting in Zimbabwe. The number of PPP contracts is further confirmed to be dependent on the availability of inward foreign direct investment flows. The influence of institutional governance quality on the number of water and sanitation PPP contracts was tested using a composite index constructed using the principal components analysis technique. It is advised that the government of Zimbabwe should strengthen their governance institutions and further develop their capital and bank credit markets, so as to attract investors to take up the water and sanitation infrastructure PPP contract opportunities available in the country.

Access to clean water is vital for public health; however, many urban households suffer from waterborne illnesses due to contamination. This study examines the economic cost of contaminated water to households in Khurda (Odisha) and Paschim Medinipur (West Bengal), focusing on diseases like diarrhea, vomiting, abdominal pain, and fever. Using a detailed questionnaire, data were gathered from 281 households. Findings show that 17% of households with piped water reported illness compared to 5.26% with non-piped water, with issues such as foul smell and red water also noted. The average household cost of illness is ₹47.69 (US$ 0.571), highlighting the need for improved water infrastructure and sanitation to address public health risks.
