SuSanA announces new project database as a one-stop shop for information on sanitation projects

A sanitation project database is now available on the website of the Sustainable Sanitation Alliance (SuSanA). It aims to make  information about sanitation projects of all organizations available in one central location.

The project database currently contains 220 projects. 80% of these have the Bill & Melinda Gates Foundation as their funding source, due to the fact that the database development was part of a BMGF grant to Stockholm Environment Institute.

Survey on sanitation in flood-prone areas – George Washington University

Dear WASH colleagues,

I am a masters student at the George Washington University (in the U.S.). As part of my thesis, I am collaborating on research that aims to better understand the options for sanitation in flood-prone areas. The aims of the study are to identify best practices, barriers, and technical methods for the implementation of sanitation in flood-prone areas. If you have had experience working on sanitation in flood-prone areas, I would greatly appreciate you sharing your experiences.  If you are willing, I invite you to participate in the following brief online survey: Survey on Sanitation in Flood Prone Areas

In addition to the online surveys, I will be conducting in-depth qualitative interviews with individuals who work on sanitation in flood-prone areas in Cambodia.  If you have implemented a sanitation project in a flood-prone area in Cambodia, and you’re interested in being part of the study, please let me know and I will forward you the informed consent form to enroll you in the study. The interview should take less than 30 minutes and can be conducted over skype, Google hangout, or over the phone, at your convenience.

Finally, if you believe that you know of someone who would be suited for this study, please feel free to forward me his or her contact information.  I appreciate your time and assistance, and please let me know if you have any questions or comments. I look forward to hearing from you!

Sincerely,
Jason Lopez, MPH Candidate – Global Environmental Health

The disgust box: a novel approach to illustrate water contamination with feces

Below are links to 5 Aug 2015 studies on digust, handwashing and maternal mortality, handwashing and NTDs, water quality awareness and breastfeeding and household characteristics and diarrhea.

The disgust box: a novel approach to illustrate water contamination with feces. Health & Science Bulletin, June 2015.

Link: http://goo.gl/3xDeen

Inadequate drinking water, sanitation and hand hygiene are responsible for approximately 800,000 deaths per year in low and middle-income countries. We evaluated the benefits of a behaviour change communication method to motivate water treatment practices in urban low income communities in Dhaka. We used a device called the ‘Disgust Box’ to provide a vivid demonstration of how piped water is contaminated with faeces to motivate people to chlorinate water. Most of the respondents were able to recall the demonstration at both four-month and one year qualitative assessments. At four months, the majority of participants stated that they still felt disgusted by the demonstration and mentioned it as a motivator for water chlorination. However, after one year, despite being able to recall the demonstration, disgust was no longer mentioned as a motivator to chlorinate water. The Disgust Box has the potential to be an effective communication method to motivate water treatment but additional research is necessary to establish a more sustainable approach to reinforce behaviour change.

Using Observational Data to Estimate the Effect of Hand Washing and Clean Delivery Kit Use by Birth Attendants on Maternal Deaths after Home Deliveries in Rural Bangladesh, India and Nepal. PLoS One, Aug 2015. Authors: Nadine Seward, et al.

Our evidence suggests that hand washing in delivery is critical for maternal survival among home deliveries in rural South Asia, although the exact magnitude of this effect is uncertain due to inherent biases associated with observational data from low resource settings. Our findings indicating kit use does not improve maternal survival, suggests that the soap is not being used in all instances that kit use is being reported.

BU is an important conditions in the district of Lalo with 917 new cases detected from 2006 to 2012. More than 49 % of the household surveyed used unimproved water sources for their daily needs. Only 8.7 % of the investigated household had improved sanitation facilities at home and 9.7 % had improved hygiene behavior. The type of housing as an indicator of the socioeconomic status, the permanent availability of soap and improved hygiene practices were identified as the main factors positively associated with improved sanitation status.

Aug 10 – Weekly Update of Selected WASH Studies

Effectiveness of emergency water treatment practices in refugee camps in South Sudan. WHO Bulletin, Aug 2015. Authors: Syed Imran Ali, Syed Saad Ali & Jean-Francois Fesselet.
Link: http://goo.gl/BtnQVh

Current guidelines for free residual chlorine in emergency water supplies are not based on field evidence and offer inadequate protection after distribution in refugee camps in South Sudan. We recommend that the free residual chlorine guideline be increased to 1.0 mg/L in all situations, irrespective of disease outbreak, pH, or turbidity conditions. This is a tentative recommendation because the degree to which these findings can be generalized to other camps in different settings is unknown.

Nutrition in Ethiopia: An emerging success story? Author: Headey, Derek D.
Link: https://goo.gl/tmMCqX

Research does not always provide the results that we expect. At the recent conference on improving nutrition in Ethiopia, Together for Nutrition 2015, we learnt about the rapid progress in Ethiopia in child nutritional outcomes that are linked to improved birth size and, hence, improved maternal health. However, most of the improvement in maternal health seems related to better sanitation, rather than to diet, care, or health factors.

Diet and specific microbial exposure trigger features of environmental enteropathy in a novel murine model. Nature Communications, Aug 2015. Authors: Eric M. Brown, et al.
Link: http://goo.gl/Sgx6XP

Here we demonstrate that early-life consumption of a moderately malnourished diet, in combination with iterative oral exposure to commensal Bacteroidales species and Escherichia coli, remodels the murine small intestine to resemble features of EE observed in humans. We further report the profound changes that malnutrition imparts on the small intestinal microbiota, metabolite and intraepithelial lymphocyte composition, along with the susceptibility to enteric infection. Our findings provide evidence indicating that both diet and microbes combine to contribute to the aetiology of EE, and describe a novel murine model that can be used to elucidate the mechanisms behind this understudied disease.

An internet-delivered handwashing intervention to modify influenza-like illness and respiratory infection transmission (PRIMIT): a primary care randomised trial. The Lancet, Aug 2015. Authors: Paul Little, Beth Stuart, et al.
Link: http://goo.gl/hHLnLI

Handwashing to prevent transmission of respiratory tract infections (RTIs) has been widely advocated, especially during the H1N1 pandemic. However, the role of handwashing is debated, and no good randomised evidence exists among adults in non-deprived settings. We aimed to assess whether an internet-delivered intervention to modify handwashing would reduce the number of RTIs among adults and their household members.

Associations between school- and household-level water, sanitation and hygiene conditions and soil-transmitted helminth infection among Kenyan school children. Parasit Vectors. 2015 Aug. Authors: Freeman MC, Chard AN, et al.
Link: http://goo.gl/HkdIyS

Results suggest mixed impacts of household and school WASH on prevalence and intensity of infection. WASH risk factors differed across individual worm species, which is expected given the different mechanisms of infection. No trend of the relative importance of school versus household-level WASH emerged, though some factors, like water supply were more strongly related to lower infection, which suggests it is important in supporting other school practices, such as hand-washing and keeping school toilets clean.

Modelling Optimal Control of Cholera in Communities Linked by Migration. Comput Math MethodsMed. 2015. Authors: Njagarah JB, Nyabadza F
Link: http://goo.gl/VU6I5G

A mathematical model for the dynamics of cholera transmission with permissible controls between two connected communities is developed and analysed. The dynamics of the disease in the adjacent communities are assumed to be similar, with the main differences only reflected in the transmission and disease related parameters. This assumption is based on the fact that adjacent communities often have different living conditions and movement is inclined toward the community with better living conditions. Our results indicate that implementation of controls such as proper hygiene, sanitation, and vaccination across both affected communities is likely to annihilate the infection within half the time it would take through self-limitation. In addition, although an infection may still break out in the presence of controls, it may be up to 8 times less devastating when compared with the case when no controls are in place.

WASHplus Weekly: Focus on Animal Waste Management

Issue 201 | August 7, 2015 | Focus on Animal Waste Management

This issue focuses on the management of animal waste and includes recent studies and resources on the environmental and health impacts of waste from domestic animals such as cattle, pigs, and chickens. Specifically, reviews of animal waste management by the International Livestock Research Institute, and diarrheal infections associated with animal husbandry are included, as well as aWHO fact sheet on Taeniasis/Cysticercosis, and country studies from Bangladesh, Egypt, Ghana, and more.

WASTE MANAGEMENT

Global Assessment of Manure Management Policies and Practices, 2014. E Teenstra. Link
The study assessed livestock manure policies in 34 countries in Asia, Africa, and Latin America, then looked in depth at manure management practices in Bangladesh, Vietnam, Ethiopia, Malawi, Argentina and Costa Rica. The authors found wide variations in practice, with particular challenges in the handling of liquid manure; they also found government policies and lack of coordination often hindered the implementation of improved practices.

Manure Management Practices in Urban and Peri-urban areas of Tanzania pose a Public Health Threat, n.d. University of Copenhagen. Link
Livestock are increasingly kept in urban and peri-urban areas as a consequence of the growing urban demand for fresh meat and livestock products. Manure is a valuable byproduct of livestock production, but if it is not treated according to good manure handling practices, it may cause a public health treat due to the presence of pathogenic bacteria in the dung. A recent international research project working with cattle farmers in urban areas of Tanzania has documented that good manure handling practices are not always followed, and that this lead to direct human contact and environmental contamination with cattle manure.

A One Health Perspective for Integrated Human and Animal Sanitation and Nutrient Recycling, 2015. H Nguyen-Viet. | Order from CABI | Free View/Download
This chapter discusses a conceptual framework for integrated health and environmental assessment that combines health status, and the physical, socioeconomic and cultural environments in order to improve human health and minimize environmental impact. This concept’s application in the management of human and animal excreta in Vietnam is then described.

Review of Evidence on Antimicrobial Resistance and Animal Agriculture in Developing Countries, 2015. D Grace, International Livestock Research Institute. Link
This short paper identifies key evidence gaps in our knowledge of livestock- and fisheries-linked antimicrobial resistance in the developing world, and to document on-going or planned research initiatives on this topic by key stakeholders. The antimicrobial resistant (AMR) infections in animals that are of most potential risk to human health are likely to be zoonotic pathogens transmitted through food, especially Salmonella and Campylobacter. In addition, livestock associated methicillin resistant Staphylococcus aureus (LA MRSA) and extended spectrum beta lactamase E. coli (ESBL E. coli) are emerging problems throughout the world.

REPORTS/ARTICLES

Finance Brief 1: Domestic Public Finance for WASH: What, Why, How? 2015. G Norman. Link
This report defines domestic public finance as funds derived from domestic taxes, raised at the national or local level. Domestic public finance is only part of the solution to service delivery in poor communities; user finance and donor finance are also part of the mix. Likewise, domestic public finance forms part of a wider governance puzzle: improving WASH services requires not just more government investment, but also diverse other elements including (for example) clear institutional mandates.
