Abstract Access to safely managed drinking water (SMDW) remains a global challenge, and affects 2.2 billion people 1,2 . Solar-driven atmospheric harvesting (AWH) devices with continuous cycling may accelerate progress by enabling decentralized extraction of from air 3–6 , but low specific yields (SY) daytime relative humidity (RH) have raised questions about their performance (in litres output per day) 7–11 However, our knowledge, no analysis has mapped the potential AWH 12 despite...
Assessments of disease burden are important to inform national, regional, and global strategies guide investment. We aimed estimate the drinking water, sanitation, hygiene (WASH)-attributable for diarrhoea, acute respiratory infections, undernutrition, soil-transmitted helminthiasis, using WASH service levels used monitor UN Sustainable Development Goals (SDGs) as counterfactual minimum risk-exposure levels.
Safe drinking water access is a human right, but data on safely managed services (SMDWS) lacking for more than half of the global population. We estimate SMDWS use in 135 low- and middle-income countries (LMICs) at subnational levels with geospatial modeling approach, combining existing household survey available datasets. that only one three people used LMICs 2020 identified fecal contamination as primary limiting factor affecting almost population LMICs. Our results are relevant raising...
Objective To determine how data on water source quality affect assessments of progress towards the 2015 Millennium Development Goal (MDG) target access to safe drinking-water.Methods Data from five countries whether drinking-water sources complied with World Health Organization guidelines contamination thermotolerant coliform bacteria, arsenic, fluoride and nitrates in 2004 2005 were obtained Rapid Assessment Drinking-Water Quality project.These used adjust estimates proportion population at...
While water and sanitation are now recognized as a human right by the United Nations, monitoring inequality in safe access poses challenges. This study uses survey data to calculate household socio-economic-status (SES) indices seven countries where national drinking-water quality surveys available. These used assess inequalities indicated type of improved source, use water, combination these. In Bangladesh, arsenic exposure through is not significantly related SES (p = 0.06) among...
The World Health Organization (WHO) and United Nations Children’s Fund (UNICEF), through the Joint Monitoring Programme (JMP), are responsible for global monitoring of Sustainable Development Goal (SDG) targets drinking water, sanitation hygiene (WASH). SDGs represent a fundamental shift in household WASH with new focus on service levels incorporation hygiene. This article reflects process establishing SDG baselines methods used to generate national, regional estimates indicators. JMP 2017...
Background Water, sanitation and hygiene (WASH) are essential for a healthy dignified life. International targets to reduce inadequate WASH coverage were set under the Millennium Development Goals (MDGs, 1990–2015) now Sustainable (SDGs, 2016–2030). The MDGs called halving proportion of population without access adequate water sanitation, whereas SDGs call universal access, require progressive reduction inequalities, include in addition sanitation. Estimating complete provides baseline...
Background: The 2030 Sustainable Development Goals (SDGs) set an ambitious new benchmark for safely managed drinking water services (SMDWs), but many countries lack national data on the availability and quality of water. Objectives: We quantified microbiological water, monitored SMDWs, examined risk factors Escherichia coli (E. coli) contamination in 27 low-and middle-income (LMICs). Methods: A module household surveys was implemented Multiple Indicator Cluster Surveys. Teams used portable...
Microbial drinking-water quality testing plays an essential role in measures to protect public health. However, such remains a significant challenge where resources are limited. With wide variety of tests available, researchers and practitioners have expressed difficulties selecting the most appropriate test(s) for particular budget, application setting. To assist selection process we identified characteristics associated with low medium resource settings specified basic information that is...
Packaged drinking water (PW) sold in bottles and plastic bags/sachets is widely consumed low- middle-income countries (LMICs), many urban users sub-Saharan Africa (SSA) rely on packaged sachet (PSW) as their primary source of for consumption. However, few rigorous studies have investigated PSW quality SSA, none compared to stored household consumption (HWC). A clearer understanding the context alternative sources needed inform policy regulation. As elsewhere Sierra Leone, but government...
The technique of plasmonic ELISA is successfully applied to detect the HIV protein gp120 at ultralow concentration 10 × 10<sup>−17</sup> g mL<sup>−1</sup>.
Disposable diaper use is widespread in many low- and middle-income countries whilst waste collection services are scarce. Despite the potential environmental public health impacts of disposable consumption by households lacking services, an international system for monitoring such lacking. This study therefore aims to develop evaluate a method estimating based on secondary data, specifically nationally representative household expenditure surveys. reported via surveys Nigeria (from 2018–19),...
Packaged water consumption is growing in low- and middle-income countries, but the magnitude of this phenomenon its environmental consequences remain unclear. This study aims to quantify both volumes packaged consumed relative household requirements associated plastic waste generated for three West African case countries. Data from expenditure surveys Ghana, Nigeria Liberia were used estimate thereby households with without solid disposal facilities. In respectively, 11.3 (95% confidence...
Microbial water quality monitoring is crucial for managing resources and protecting public health. However, institutional testing activities in sub-Saharan Africa are currently limited. Because the economics of poorly understood, extent to which cost may be a barrier different settings unclear. This study used data from 18 African institutions (piped suppliers health surveillance agencies six countries) estimates supply type coverage 15 countries assess annual financial requirements...
Background The Sustainable Development Goals (SDGs) require household survey programmes such as the UNICEF-supported Multiple Indicator Cluster Surveys (MICS) to enhance data collection cover new indicators. This study aims evaluated methods for assessing water quality, availability, emptying of sanitation facilities, menstrual hygiene management and acceptability quality testing in households which are key monitoring SDG targets 6.1 6.2 on drinking Water, Sanitation Hygiene (WASH) emerging...
