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.

ObjectiveTo determine the magnitude of relationships of early life factors with child development in low/middle-income countries (LMICs).DesignMeta-analyses of standardised mean differences (SMDs) estimated from published and unpublished data.Data sourcesWe searched Medline, bibliographies of key articles and reviews, and grey literature to identify studies from LMICs that collected data on early life exposures and child development. The most recent search was done on 4 November 2014. We then invited the first authors of the publications and investigators of unpublished studies to participate in the study.Eligibility criteria for selecting studiesStudies that assessed at least one domain of child development in at least 100 children under 7 years of age and collected at least one early life factor of interest were included in the study.AnalysesLinear regression models were used to assess SMDs in child development by parental and child factors within each study. We then produced pooled estimates across studies using random effects meta-analyses.ResultsWe retrieved data from 21 studies including 20 882 children across 13 LMICs, to assess the associations of exposure to 14 major risk factors with child development. Children of mothers with secondary schooling had 0.14 SD (95% CI 0.05 to 0.25) higher cognitive scores compared with children whose mothers had primary education. Preterm birth was associated with 0.14 SD (–0.24 to –0.05) and 0.23 SD (–0.42 to –0.03) reductions in cognitive and motor scores, respectively. Maternal short stature, anaemia in infancy and lack of access to clean water and sanitation had significant negative associations with cognitive and motor development with effects ranging from −0.18 to −0.10 SDs.ConclusionsDifferential parental, environmental and nutritional factors contribute to disparities in child development across LMICs. Targeting these factors from prepregnancy through childhood may improve health and development of children.

Safe water and sanitation, which give rise to appropriate hygiene, are fundamental determinants of individual and social health and well-being. Thereby, assessing and widening access to sustainable, durable water and sanitation infrastructure remains a global health issue. Rural areas are already at a disadvantage. Poor access to water, sanitation, and hygiene (WASH) can have a major negative effect on students in rural schools. Thus, the paper aims to assess the current condition and the challenge to access WASH in rural Kazakh schools. The study was conducted in three rural schools in Central Kazakhstan. Data were gathered through a survey among pupils, observations of the WASH infrastructure and maintenance, and a face-to-face interview with school administrators. The mean survey response rate was 65% across schools. Results indicated there was no alternative drinking-water source in schools, and 15% of students said they had access to water only occasionally. Half of the students reported that the water was unsafe to drink because of a poor odor, taste, or color. The toilet in school 3 was locked with a key, and a quarter of the students reported there was no access to a key. Moreover, not having gender-separated toilet facilities was a challenge because of the traditional gender norms. Despite the effective regulations and measures of handwashing taken during COVID-19, 27.7% of the students answered that soap was not offered daily in classrooms. Additionally, warm water was only provided in school 2. About 75% of students did not have access to drying materials continuously. The study shows that having the schools’ infrastructure is not enough when characteristics, such as availability, accessibility, maintenance, operation, quality of services, education, and practices, are ignored. Cooperation between local education authorities, school administration, and parents should be encouraged to the achievement of the sustainable development goals (SDGs) by 2030.

Abstract The recognition of the human right to water and sanitation (HRtWS) by the United Nations General Assembly and Human Rights Council in 2010 constituted a significant political measure whose direct consequences are still being assessed. Previous to this date, the HRtWS and its link to a healthy life and adequate standard of living had been recognised in diverse legal and judicial spheres worldwide, in some cases under the pressure of the initiatives of strong social movements. However, while the HRtWS is recognised by the UN State Members, it constitutes a concept in construction that has not been approached and interpreted in consensual ways by all concerned stakeholders. The present article presents a formal definition of this right with a base in human rights regulation. It attempts to dialogue with the different existing perspectives regarding the impact of its international recognition as a human right. It then elucidates the progressive development of the HRtWS in law and jurisprudence. Finally, it considers the urgency and challenge of monitoring the HRtWS and discusses important implications for public policies. Resumo O reconhecimento do direito humano à água e ao saneamento (HRtWS) pela Assembleia Geral das Nações Unidas e pelo Conselho de Direitos Humanos, em 2010, constitui uma medida política significativa cujas consequências diretas ainda estão sendo avaliadas. Anterior a esta data, a relação entre HRtWS com uma vida saudável e um padrão de vida adequado já havia sido reconhecida em diversas esferas legais e jurídicas em todo o mundo, em alguns casos devido à pressão das iniciativas de movimentos sociais fortes. No entanto, mesmo que o HRtWS tenha sido reconhecido pelos Estados Membros das Nações Unidas, ele constitui um conceito em construção que não tem sido abordado e interpretado de maneira consensual por todos os atores interessados. O presente artigo apresenta uma definição formal desse direito com base no regulamento de direitos humanos. Tenta dialogar com as diferentes perspectivas existentes sobre o impacto do seu reconhecimento internacional como um direito humano. Em seguida, esclarece o desenvolvimento progressivo dos HRtWS na lei e na jurisprudência. Por último, considera a urgência e o desafio de monitorar os HRtWS e discute implicações importantes para políticas públicas.

Poverty in Nigeria is at extremely high levels and represents one of the many economic hardships faced by the Nigeria population. One of the factors potentially contributing to present high poverty levels is poor environment quality which is prevalent in Nigeria and which may result in increased poverty levels as efforts are undertaken to address adverse environment quality. This paper explored the effect of environment quality on poverty reduction in Nigeria using data from the World Bank World Development indicators over the period of 1990 to 2015. The study employed Augmented Dickey Fuller unit root test, and Autoregressive Distributed Lag (ARDL) estimation in analyzing data and the findings of the study revealed that improved environment quality as measured by improved access to sanitation and access to electricity positively and significantly increase poverty level in Nigeria, possibly on account of the increased financial and social costs of gaining access to sanitation and electricity. It is recommended that policy makers ensure that policies aimed at improving environment quality in Nigeria take into account the adverse implications of improving environment quality for poverty so as to ensure that a balance is achieved between improved environment quality and reduced poverty so that a cleaner environment is achieved at lower financial and welfare cost to citizens.

Water scarcity, climate change, price volatility, agricultural output variability, and geo-political instability have determined new stressors and situations of risks that exert pressure on agro-ecological systems, farmers, people's food security, and generally affect the well-being of the population. In recent times, resilience is seen as providing a new approach on how to analyse the effects of shocks and stressors that threaten people's well-being. The question is whether there is a relationship between the inadequate access to basic services, as stressor of people's physical access to food and food availability on the market, and food security, as an outcome of people's well-being. Statistical data have been analysed with simple regression model. The case study of Romania is discussed, using twenty-two observations. The main findings show that access to essential services, such as water and sanitation, are important in explaining household's resilience capacity. Other stressors, such as rail lines density and road density, which determine the physical access to markets, have a less significant influence on food security. The relevance of the results lies in their capacity to emphasize the role of people's access to basic needs in strengthening the resilience of individuals, families and regions, and to ensure, as a consequence, food security.

Shared sanitation facilities are critical for universal access to sanitation. This exploratory study examines the role that free shared sanitation facilities play in equalizing sanitation access in peri-urban India, where, despite extensive state-led efforts towards universal access, household toilets remain infeasible for the country’s poorest citizens. We conducted one-on-one semi-structured interviews with 39 shared sanitation facility users in two peri-urban communities in Jharkhand, India. Participants were recruited after they used the sanitation facility. Data were analyzed using both deductive and inductive coding and thematic analysis. We found that clean and safe community sanitation facilities were used by people when at home, and were used both by those with and without a home toilet. We also found (consistent with previous work) that when people were outside of the home for work, school, and errands, they often needed but did not have access to usable toilets. These findings suggest why, and under what conditions, shared sanitation facilities are essential to realizing the human right to sanitation. Shared facilities are complements to, and not substitutes for, household facilities. Global sanitation targets, therefore, should be modified to reflect the role of well-maintained shared sanitation in meeting the goal of universal access.

This book suggests how that exploration should be undertaken, and how a monitoring system that has a solid conceptual basis and is both easy to operate and reasonable in cost can then be put into practice. Long the ideal of many scholars and observers of urban problems, such a system may now be close to realization. In this book, examples of Latin American cities are used as case studies. As argued in the first chapter, there are good reasons to concentrate on Latin America: it is the world region with the most rapid urban development and is the most urbanized region in the developing world. In contrast to residents of cities in poorer regions, Latin Americans have managed to democratize homeownership and to extend basic services to the majority of households. That means that improving the Quality of Life (QoL) in Latin American cities is no longer primarily a matter of bricks and mortar. But the challenges are as large as they are diverse. Chapter two introduces the reader to the hedonic price and the life satisfaction approaches and presents a comparative summary of the conclusions of the six case studies. This chapter, like the first, is essential for the policy maker or activist in urban affairs who wants to understand the possibilities of the new systems for monitoring the quality of urban life. Chapter three is a concise and self-contained introduction to the economic theory on which the hedonic pricing and life satisfaction approaches are based and which forms the backbone of this book. Chapters four-eight then summarize the most notable findings of the case studies, each emphasizing a different topic and focus.

Background Malaria remains a major public health challenge in sub-Saharan Africa, and its burden may be influenced by access to clean water, sanitation, and childhood vitamin A supplementation. Understanding how these indicators relate to malaria incidence can help inform targeted prevention strategies. Methods Country-level data from global health databases were analyzed using nonparametric statistical tests and machine learning models. The Kruskal–Wallis test and Dunn’s post hoc comparisons were used to assess differences in malaria incidence across categories of water and sanitation access. Cliff’s delta was used to measure effect sizes. Tree-based machine learning models and logistic regression were trained to evaluate the predictive strength of the three indicators. Results Significant differences in malaria incidence were found across water and sanitation access groups, with the lowest access groups consistently exhibiting the highest incidence. Cliff’s delta indicated large effect sizes, particularly between low and high access categories. Vitamin A supplementation showed statistically significant group differences, though effect sizes were generally small. Tree-based machine learning models showed moderate predictive performance and outperformed logistic regression in classification accuracy and recall. Conclusions Access to clean water and adequate sanitation are strongly associated with lower malaria incidence, underscoring their importance in malaria control efforts. While vitamin A supplementation shows weaker associations, it may still interact with broader health conditions. These findings highlight the essential role of basic infrastructure in reducing malaria burden and demonstrate the potential of predictive modeling to support future global health research.

Water and sanitation affordability has drawn researchers’ attention over the past years due to the recent economic crisis and the growing role of tariffs on funding services. This paper conducted a systematic review of previous research on water and/or sanitation affordability and a critical qualitative discussion on the methodologies adopted. The research framework relied on a hybrid approach that combines systematic quantitative and narrative analyses. The literature review protocol applied returned 79 relevant studies published by journals and recognized international organizations and four key topics, namely affordability indicators, threshold, data source, and practical use of the analysis were identified and critically discussed. This paper contributes to the literature by presenting and discussing the most important water affordability issues and enlightening the potential role of the analysis in public financial policies.
