Abstract Climate change presents a major threat to water and sanitation services. There is an urgent need understand improve resilience, particularly in rural communities small towns low- middle-income countries that already struggle provide universal access services face increasing threats from climate change. To date, there lack of simple framework assess the resilience which hinders development strategies An interdisciplinary team engineers environmental social scientists were brought...
This article considers the degree to which achieving equity in Global North–South research partnerships is possible under current UK funding models. While there has been significant discussion with respect decolonisation of research, it will be argued that some distance between language articulated currently by bodies, and realities working as a project partner South. The draws on prior ongoing experiences multidisciplinary team researchers brought together UK-funded project. In interests...
Abstract Climate change poses a threat to water security where both current and future generations are concerned, with its accompanying impacts set be greater in low‐ middle‐income countries (LMICs). As result, questions pertaining climate adaption LMICs receiving increased attention from academics policymakers alike. It is broadly accepted that top‐down approaches developing resilience challenges have been shown limited concerted efforts need made engage local communities advancing adaptive...
Understanding the resilience of water supplies to climate change is becoming an urgent priority ensure health targets are met. Addressing systemic issues and building community-managed supplies, which serve millions people in rural LMIC settings, will be critical improve access safe drinking water. The How Tough WASH (HTIW) framework assess was applied Ethiopia Nepal effectiveness this field conditions. these measured along six domains—the environment, infrastructure, management,...
Abstract BACKGROUND This study evaluates the capacity of hydroxyapatite ceramics to remove fluoride from drinking water. Porous ceramic beads approximately 5 mm in diameter were fabricated using soluble potato starch as well insoluble rice starch, wheat corn and cellulose pore‐forming agents. RESULTS Calcination particles, followed by mixing with starches water, compaction, sintering at 1200 °C resulted formation macroporous maximum adsorption capacities ranging 7 12 mg g −1 , depending on...
This study examines how Northwest Syria’s arable and irrigated areas are changing, with a particular emphasis on processes that have affected cultivation water availability since 2011. A substantial decline in cultivated is revealed by the analysis of 502 samples from various stakeholders, including farmers, well owners, well-digging companies, agricultural pharmacies, service offices. District-specific variations show decrease 15.3% 8.5% total land areas, respectively. Particularly known...
The study investigates the impact of Syrian crisis and recent drought on potable water situation in Northwest Syria, comparing various aspects availability quality before after 2011. 380 key-informants were surveyed, including water-well owners, well-digging companies, water-trucking suppliers, agricultural pharmacies, service offices within local councils. surveys covered all nine districts northwestern Syria across Aleppo Idleb governorates. survey findings reveal significant shifts...
Fluoride uptake by porous hydroxyapatite ceramics is investigated through batch adsorption studies to determine the effect of varying size grains and pore size. It found that made from fine (d50=100 μm) have higher fluoride smaller pores compared with coarse (d50=240 (18.2 mg/g versus 12.4 mg/g, respectively). Fewer processing steps are required for hydroxyapatite. This ceramic has high selectivity relative anions commonly in groundwater natural organic matter (NOM) can be regenerated up...
Batch kinetic tests and continuous-flow column experiments were conducted to study fluoride adsorption on porous hydroxyapatite ceramics. showed that uptake occurred faster for smaller adsorbent particles, which is expected ceramics with internal sorption sites. Columns different flow rates had breakthrough curves. Fluoride loading the (q) at point of exhaustion (Ceff = 0.85 C0) increased decrease in rate, while mass 0.15 stayed nearly constant. Flow interruption points led a temporary...
On-site sanitation systems (OSS), such as pit latrines, are an important source of methane (CH4), with emissions increasing when they wet, and this occurs anaerobic conditions dominate. This paper presents the development a model, which uses seasonal changes in groundwater to account for fluctuating inundation and, therefore, associated CH4 from varying degrees anerobic examined. Given that observed timeseries table depth at high enough spatial temporal resolutions often difficult obtain...
Climate change threatens the health and well-being of populations. We conducted a risk assessment two climate-related variables (i.e., temperature rainfall) associated water, sanitation hygiene (WASH)-related exposures vulnerabilities for people living in Mopani District, Limpopo province, South Africa. Primary secondary data were applied qualitative quantitative to generate classifications low, medium, or high) components hazard/threat, human exposure, vulnerability. Climate-related threats...
This study evaluated the experience of implementing water safety plans (WSPs) in Vietnam. WSPs were introduced Vietnam by World Health Organization (WHO) collaboration with Ministry Construction 2006 and have been a mandatory requirement for municipal supplies since 2012. Using mixed-methods approach, we collected data on perceived benefits challenges WSP implementation from 23 provincial companies between August November 2021. Potential public health improved quality key motivation; 87%...
Climate change threatens the safety of water supplies globally, but small in rapidly growing and urbanizing towns low- middle-income countries are especially at risk. Despite efforts Government Ethiopia, research shows that small-town utilities Ethiopia poorly equipped to prioritize developing maintaining climate-resilient services. We applied How tough is WASH framework for climate resilient ten town Eastern identify their strengths weaknesses preparing change. found reports weak...
ABSTRACT Water supply schemes (WSSs) in Nepal are managed by water user committees with basic knowledge of climate change. The Government has committed and prioritized improving the quality services implementing climate-resilient safety plans (CR-WSPs) 10 WSSs as pilot projects. In this study, how tough is sanitation hygiene (HTIW) framework was adopted to assess effectiveness these CR-WSPs, which include four groundwater six protected springs-based WSSs. Employing HTIW framework, study key...
Building a resilient water, sanitation, and hygiene (WASH) system is more important than ever since climate change threatens WASH, particularly in low- middle-income countries. The Government of Ethiopia stresses climate-resilient WASH through its One National Program, albeit it may be challenging to ascertain the resilience due absence an easy-to-use monitoring tool. “How tough WASH” framework recently developed monitor community-managed rural water supply change. We investigated whether...
