We investigate the impacts of access to piped water on drinking water quality, sanitation, hygiene and health outcomes in marginalized rural households of north-western Bangladesh, using a quasi-experimental setup. A government organization – the Barindra Multipurpose Development Authority (BMDA) – established a piped water network to connect rural households with the deep ground water resources and improve their access to potable water. Using propensity score matching, the study compares a treatment and a control group of households to identify gains in water-sanitation, hygiene and health outcomes. In terms of water safety, we find no improvement in the quality of drinking water, measured by E. coli count per 100 ml of water at the point of use (i.e. the pots and jars used to store it). Food utensils tested positive for E. coli in both the control and treatment group, thus showing no improvement through the BMDA intervention. Hygiene behavior such as handwashing with soap after defecation or before feeding children also does not improve. Finally, we do not find evidence of health benefits, such as decreased diarrhea incidence of under-five children or improved nutritional outcomes such as stunting, underweight and wasting. Although access to BMDA piped water in the premises is subject to a fee, it seems this incentive mechanism is not strong enough to improve water behavior or its outcomes: treated households are as poor as the non-treated in terms of maintaining hygiene and water quality, possibly because of lack of information.

The increasing costs of energy and water, fossil fuel depletion, and food shortages caused by climate change challenge long-term sustainability of food, energy, and water (FEW) systems. In working toward sustainable development, a fundamental question for deciding on whether and how to invest in FEW systems is “how sustainable FEW systems are?”. In order to measure sustainability across the FEW systems, an integrated sustainability index (SI) is developed. The SI is comprised of three components; food, energy, and water. These components each consist of different sub-components (e.g. transportation fuel for energy component) that make up integrated FEW systems. The sustainability of an FEW system can be calculated using the integrated FEW SI, but a more thought provoking question is to understand how each sub-component affects overall sustainability of the system. This cannot be achieved without formulating the interconnections associated with FEW components. This study formulates interconnections associated with FEW components. In an effort to increase the degree to which the results would generalize to FEW systems with different scales, the calculations of the study are performed for a sustainable FEW system that can consistently yield food for a family of four (two adults and two children) and supply its own water and energy needs from sustainable sources. Also, the sustainability is measured for two systems located in two different climates; one is relatively cloudy and humid and the other is sunny and arid. The results show that the highest sustainability improvement in both climates is associated with irrigation sub-component. Not only a sustainable water supply for irrigation sub-component improves the sustainability of water component, it also improves food sustainability and consequently energy sustainability. This finding can be explained by the fact that the irrigation sub-component is a resource supplier for grain sub-component, and that is a resource supplier for transportation fuel sub-component.

To explore the perceptions of food access by African American women in Flint, MI.Using womanist theory, in which African American women's experiential knowledge centered the analysis, 8 focus groups were conducted during fall/spring, 2014–2015. Seventeen mothers aged 21–50 years with children aged <18 years and 13 women aged >60 years comprised the groups.The high cost of water, poor availability of healthy foods in inner-city stores, and limited transportation were barriers to accessing healthy food. Conversely, receiving food from food giveaways, friends, and family, as well as access to transportation facilitated food access. These women also reported discriminatory experiences and diet-related health concerns. Participants were keenly aware of available free community resources and gender, racial, and income barriers to accessing them.Understanding these barriers and facilitators provides information to aid local food policy assistance decisions and inform community-based interventions, especially given the lead contamination of water and the purported importance of a healthy diet to sequester lead.

Civil conflict began in Ethiopia in November 2020 and has reportedly caused major disrup tions in access to health services, food, and related critical services, in addition to the direct impacts of the conflict on health and well-being. However, the population-level impacts of the conflict have not yet been systematically quantified. We analyze high frequency phone surveys conducted by the World Bank, which included measures of access to basic ser vices, to estimate the impact of the first phase of the war (November 2020 to May 2021) on households in Tigray. After controlling for sample selection, a difference-in-differences approach is used to estimate causal effects of the conflict on population access to health services, food, and water and sanitation. Inverse probability weighting is used to adjust for sample attrition. The conflict has increased the share of respondents who report that they were unable to access needed health services by 35 percentage points (95% CI: 14–55 pp) and medicine by 8 pp (95% CI:2–15 pp). It has also increased the share of households unable to purchase staple foods by 26 pp (95% CI:7–45 pp). The share of households unable to access water did not increase, although the percentage able to purchase soap declined by 17 pp (95% CI: 1–32 pp). We document significant heterogeneity across popula tion groups, with disproportionate effects on the poor, on rural populations, on households with undernourished children, and those living in communities without health facilities. These significant disruptions in access to basic services likely underestimate the true bur den of conflict in the affected population, given that the conflict has continued beyond the survey period, and that worse-affected households may have higher rates of non-response. Documented spatial and household-level heterogeneity in the impact of the conflict may help guide rapid post-conflict responses.

We have previously shown that diarrheagenic Escherichia coli (DEC) and non-DEC are prevalent in food sources and irrigation water in South Africa. Recent data suggest that an increased relative abundance of faecal Enterobacteriaceae is associated with poorer health outcomes among children in developing countries. Thus, exposure to non-DEC from environmental sources may incur adverse effects, although the mechanisms underlying these effects remain obscure. To further elucidate this phenomenon, we assayed non-DEC strains from environmental sources in South Africa for phenotypes that may be associated with intestinal dysfunction (ID). DEC strains were also used. The strains had previously been isolated from Producer Distributor Bulk Milk (PDBM), irrigated lettuce, street vendor coleslaw and irrigation water.In-vitro assays identified; biofilm formation (n = 38), extracellular polymeric substance (EPS) formation (n = 38), cytotoxic activity (n = 10), disruption of tight junctions and induction of Interleukin 8 (IL-8) on polarized T-84 cells (n = 20). The number of strains tested for each assay differed, depending on prior molecular and phenotypic characterization that signalled potential pathogenicity in-vitro. Subsequently, all strains having data points for all analyses were used to compute Principal Component Analysis (PCA) plot curves to infer potential associations amongst test strains and a standard DEC pathogenic strain (042).Biofilm formation on glass coverslips after strains were grown in nutrient-rich media (LB and DMEM-F12 + 0.5% D-Mannose) at 37 °C varied based on pathotype (DEC and non-DEC) and source of isolation (food, irrigation water, clinical) suggesting that pathotype and source isolation influence persistence within a defined environmental niche. Additionally, DEC isolated from irrigated lettuce had a significantly higher (p ≤ 0.05) propensity for biofilm formation in both media compared to all strains including DEC standard controls. This suggested the propensity for irrigated lettuce as a potential source of persistent pathogenic strains. Furthermore, all strains were able to form EPS suggesting the ability to form mature biofilms under conditions relevant for food processing (20–25 °C). Of the (60%, 6 out of 10) strains that showed cytotoxic activity, most (83%, 5 out of 6 strains) were non-DEC isolated from food sources many of which are consumed with minimal processing.Mean percentage reduction in initial TEER (a measure of intestinal disruption), did not significantly differ (p = 0.05) in all test strains from that observed in the standard DEC. Additionally, IL-8 induction from strains isolated from PDBM (139 pg/mL), irrigation water (231.93 pg/mL) and irrigated lettuce (152.98 pg/mL) was significantly higher (p ≤ 0.05) than in the commensal strain aafa. PCA categorized strains based on sources of isolation showed potential for use in source tracking especially when comparing many strains from various environmental sources. We show that non-DEC strains along the food chain possess characteristics that may lead to ID. Further investigations using a larger collection of strains may provide a clearer link to these reported observations that could be associated with the high diarrheal disease burden within the country, especially among infants.

PURPOSE: The French Nutri-Bébé 2013 study aimed to assess the nutritional intake of infants and young children in comparison with the recommendations of the 2013 European Food Safety Authority (EFSA). METHODS: This cross-sectional study enrolled a random sample of families selected according to the Quota sampling method. A 3-day dietary record was conducted and supervised by two face-to-face interviews. All foods and beverages consumed were qualitatively and quantitatively reported in a diary, and their composition calculated using a food composition database. RESULTS: A total of 1035 non-breastfed children were included. Formula was abandoned early, amounting to approximately 50% of the total food intake at 7 months in 50% of infants and 22% at 1 year. A similar trend was observed for specific complementary foods. After 1 year, 50% of children consumed cow’s milk, which was semi-skimmed in 88% of cases. Drinking water intake was low. Protein intake reached 1.4 times the average requirements before 3 months, 2 times at 8–9 months, and > 4 times at 30–35 months. Fat intake was below the EFSA adequate intake (AI) in > 90% of children. Alpha-linolenic acid intake was equal to or greater than the AI in all infants < 3 months, 85% of children at 6 months, 34% at 12–17 months, and 8% >24 months. Regardless of age, docosahexaenoic acid (DHA) intake was less than the AI. CONCLUSION: Strong discrepancies are observed between the actual and recommended intake in young, non-breastfed children namely, a high-protein intake, and a low fat intake, especially DHA.

World hunger, according to the 2012 Global Hunger Index (GHI), has declined somewhat since 1990 but remains “serious.” The global average masks dramatic differences among regions and countries. Regionally, the highest GHI scores are in South Asia and Sub-Saharan Africa. South Asia reduced its GHI score significantly between 1990 and 1996—mainly by reducing the share of underweight children— but could not maintain this rapid progress. Though Sub-Saharan Africa made less progress than South Asia in the 1990s, it has caught up since the turn of the millennium, with its 2012 GHI score falling below that of South Asia. From the 1990 GHI to the 2012 GHI, 15 countries reduced their scores by 50 percent or more. In terms of absolute progress, between the 1990 GHI and the 2012 GHI, Angola, Bangladesh, Ethiopia, Malawi, Nicaragua, Niger, and Vietnam saw the largest improvements in their scores. Twenty countries still have levels of hunger that are “extremely alarming” or “alarming.” Most of the countries with alarming GHI scores are in Sub-Saharan Africa and South Asia (the 2012 GHI does not, however, reflect the recent crisis in the Horn of Africa, which intensified in 2011, or the uncertain food situation in the Sahel). Two of the three countries with extremely alarming 2012 GHI scores—Burundi and Eritrea—are in Sub-Saharan Africa; the third country with an extremely alarming score is Haiti. Its GHI score fell by about one quarter from 1990 to 2001, but most of this improvement was reversed in subsequent years. The devastating January 2010 earthquake, although not yet fully captured by the 2012 GHI because of insufficient availability of recent data, pushed Haiti back into the category of “extremely alarming.” In contrast to recent years, the Democratic Republic of Congo is not listed as “extremely alarming,” because insufficient data are available to calculate the country’s GHI score. Current and reliable data are urgently needed to appraise the situation in the country. | Non-PR | IFPRI2; GRP24 | COM; MTID; DGO; EPTD; PHND; WCAO
