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!

WASH 2016 Conference – Pathways to universal and sustained water, sanitation and hygiene – abstracts now open
WASH 2016 Conference – Pathways to universal and sustained water, sanitation and hygiene, May 16-20, 2016, Brisbane, Australia.
- WASH conference 2016 – abstracts now open
The future of action on WASH (water, sanitation and hygiene) looks positive – with the post-2015 Sustainable Development Goals global agenda maintaining attention on the need for water, sanitation and hygiene for everyone, all the time. But the path to achieving this global agenda requires new ways of thinking.
How can all WASH actors – governments, private sectors and civil society – work together to ensure WASH, whether at community-scales or larger institutional-scales, to achieve not only sustained access for everyone, but also health, well-being, environmental and economic outcomes for societies?
This and many more questions will be explored at the WASH 2016 conference in Brisbane, Australia 16-20 May, 2016.
Abstracts (oral, poster and training program) are now accepted for the two-day conference and the three-day training program.
Abstracts are welcome in the following categories:
- Improving WASH service levels and service sustainability
- Moving WASH beyond the household
- Integrating hygiene to ensure health outcomes
- WASH and water security

The latest results from the Global Sanitation Fund (GSF) show that national programmes stretching from Cambodia to Senegal have enabled close to 10 million people in more than 36,500 communities to end open defecation.
These results are published in the GSF’s latest Progress Report, highlighting cumulative results from the start of the fund up to the middle of 2015. Nationally-led programmes supported by the GSF have helped:
- 8.21 million people access improved toilets
- 9.92 million people in 36,524 communities live in open defecation free environments
- 13.46 million people access handwashing facilities
Currently, 2.4 billion people, close to 35 percent of the global population, lack access to decent sanitation. Of those, close to a billion defecate in the open. Diarrheal disease, largely caused by poor sanitation and hygiene, is a leading cause of malnutrition, stunting and child mortality, claiming nearly 600,000 lives of children under 5 every year. Inadequate facilities also affect education and economic productivity and impact the dignity and personal safety of women and girls.
Established by WSSCC, the GSF funds behaviour change activities to help large numbers of poor people in the hardest-to-reach areas attain safe sanitation and adopt good hygiene practices. These activities are community-led, support national efforts, and bring together a diverse group of stakeholders in order to address, at a large scale, the severe deficiencies in access to sanitation and hygiene.
The GSF is a pooled financing mechanism with the potential to further accelerate access to sanitation for hundreds of millions of people over the next 15 years. Between 2014 and mid-2015, the GSF reported a 95 percent increase in people with improved toilets across target regions in 13 countries. During this same period, the GSF has also supported a more than 40 percent increase in the number of people living in open defecation free environments in those same areas. The United Nations system has identified global funds as an important tool to enable member countries to achieve their national development targets, including those for sanitation and hygiene. Read more
Results reported by the GSF have been achieved due to the work of more than 200 partners, including executing agencies and sub-grantees composed of representatives from governments, international organizations, academic institutions, the United Nations and civil society. One of the strongest success factors in the GSF approach is that it allows flexibility for countries to develop their programmes within the context of their own institutional framework and according to their own specific sanitation and hygiene needs, sector capacity and stakeholders. This implementation methodology is used to reach large numbers of households in a relatively short period of time and is vital for scaling up safe sanitation and hygiene practices.
The Governments of Australia, Finland, the Netherlands, Norway, Sweden, Switzerland and the United Kingdom have contributed to the GSF since its establishment in 2008. More than $109 million has been committed for 13 country programmes, which aim to help more than 36 million people end open defecation.

South Africa’s Equitable Share Formula is a mechanism for transfer of funds from central to local government, to support basic services including water and sanitation. This Finance Brief outlines how the system works, and reports on its use for water and sanitation. There are a number of problems with implementation of the Equitable Share in South Africa; however, we consider that the mechanism per se is good, and can be a useful model for other countries.

Recordings from webinar with BMGF grantees: “What constitutes success for CLTS? – Measuring community outcomes and behavior change”
In July a webinar took place with the title “What constitutes success for CLTS? – Measuring community outcomes and behavior change”. The recordings of this webinar are now available as sound files (podcasts) and as videos. In the webinar, experts working with funding from the Bill and Melinda Gates Foundation’s “Building Demand for Sanitation” Programme shared their insights on this topic.
The webinar had a chat show format where, following a panel interview, the audience had the chance to interact with the panelists. The sound-only mp3 files should be useful for people without access to Youtube or for those who would like to listen to the webinar recordings on their mobile phones while commuting or travelling for example.
- Introduction by Pippa Scott (Euforic Services): Link to recording on YouTube
- Chat show with panelists: Ada Oko Williams (WaterAid), Darren Saywell (Plan), Hans-Joachim Mosler (EAWAG), Jonny Crocker (UNC); moderator: Jane Bewan (WSP): Link
- Feedback from breakout rooms: Link
- Closing panel: Link
- Links to all audio files and additional readings are available on the SuSanA discussion forum on page 2 of the discussion thread
- Playlist to all the webinar videos on Youtube (all playlists of SuSanA are available here)
- Information about the BDS portfolio of the BMGF is available here in a recent portfolio update and overview report (June 2015)
The webinar had an innovative format. It was run in a “chat show” format – with a set of interview questions to the panel and without powerpoint presentations. It also included four “break-out rooms” where participants could speak to each other in smaller groups, therefore allowing for more interactions.
Some general conclusions from the webinar:
1. ODF (open defecation free) may be better suited for motivating communities than measuring success and is not a good metric for comparing communities due to its binary nature;
2. Low overall success rates suggest we are missing an opportunity to better target CLTS to specific communities and consider alternate sanitation strategies where CLTS is not appropriate;
3. We need better data and understanding of how to successfully change long-term social norms.
The webinar was organized under the Knowledge Management initiative of the Building Demand for Sanitation (BDS) program of the Bill & Melinda Gates Foundation. It was organized by Euforic Services, the SuSanA secretariat and the Stockholm Environment Institute. It was aiming to address these questions: “It is startling that there seems to be no consensus about what constitutes success for CLTS programmes. Is 30% an acceptable success rate? How can these rates be optimized? and; what should be our response to communities that do not become defecation free?”

Small Doable Actions: A Feasible Approach to Behavior Change Learning Brief, 2015. WASHplus.
A small doable action is a behavior that, when practiced consistently and correctly, will lead to personal and public health improvement. It is considered feasible by the householder, from HIS/HER point of view, considering the current practice, the available resources, and the particular social context. Although the behavior may not be an “ideal practice,” more households likely will adopt it because it is considered feasible within the local context.
Over-Reporting in Handwashing Self-Reports: Potential Explanatory Factors and Alternative Measurements.PLoS One, Aug 2015. Authors: Nadja Contzen , Sandra De Pasquale, Hans-Joachim Mosler
Handwashing interventions are a priority in development and emergency aid programs. Evaluation of these interventions is essential to assess the effectiveness of programs; however, measuring handwashing is quite difficult. Although observations are considered valid, they are time-consuming and cost-ineffective; self-reports are highly efficient but considered invalid because desirable behaviour tends to be over-reported. Socially desirable responding has been claimed to be the main cause of inflated self-reports, but its underlying factors and mechanisms are understudied. The present study investigated socially desirable responding and additional potential explanatory factors for over-reported handwashing to identify indications for measures which mitigate over-reporting.
Does building more toilets stop the spread of disease? Impact evidence from India, Aug 2015.
A 3ie-funded impact evaluation research team used a cluster-randomised controlled trial to evaluate the government’s Total Sanitation Campaign in Odisha, India to see if latrine coverage did indeed reduce exposure to disease. The intervention mobilised households in villages characterised by high levels of open defecation to build and use latrines. The study was conducted between May 2010 and December 2013, involving more than 50,000 individuals in 100 villages. The study results show that the assumption that more latrines will reduce exposure to faecal pathogens, and therefore disease, does not necessarily hold true. During the study period, latrine coverage in the intervention villages increased from 9 per cent of households to 63 per cent, compared to an increase from 8 per cent to 12 per cent in the control villages. The increase in latrine coverage did not prevent diarrhoea or reduce soil-transmitted helminth infection in the intervention villages. The seven-day prevalence of reported diarrhoea in children younger than 5 years was 8.8 percent in the intervention group and 9.1 percent in the control group.
Can disgust and shame lead to cleaner water and more handwashing? Impact evidence from Bangladesh, Aug 2015.
3ie supported a research team to conduct a randomised impact evaluation between 2011 and 2014. The team tested whether behaviour change messages provoking disgust and shame amongst people within each compound are more effective than public health-related messages promoting safe water and handwashing. This brief distills the main findings and the lessons learned. The impact evaluation showed that the intervention did not change behaviours. The messages aimed at creating disgust and shame did not increase demand for water treatment or improve handwashing behaviour compared to the standard health messages. Use of the chlorine dispenser was low. This study pointed up a number of implementation factors that may have affected the impact of the messages and use of the dispensers.

The Sustainable Sanitation Alliance (SuSanA), in partnership with End Water Poverty, is holding a 2 week thematic discussion on exploring whether the new SDG indicators on sanitation will address the gaps left by the MDGs and what the SDGs can do differently to ensure those most in need have their human right to water and sanitation realised.
Running for two weeks from Tuesday 1 September to Monday 14 September on the SuSanA online discussion forum, the discussion will look at a number of key issues relating to sanitation in the SDGs and within the post-2015 development agenda. Join us to post your questions, debate with lead experts in the field, and provide your insights and knowledge on the following issues:
- Theme I – SDG indicators: The MDGs did not succeed in ensuring everyone has access to safe sanitation – will the new SDG indicators on sanitation increase progress to ensure that everyone has their right to water and sanitation realised?
- Theme 2 – Prioritising those most in need: How do we ensure that the SDGs prioritise, and monitor progress, for those most in need of safe sanitation? How do we ensure that they realise the human right to water and sanitation?
- Theme 3 – Civil society’s role in monitoring: How can civil society contribute to the monitoring of the goals and targets? What will our role need to be to ensure improvements for all?
- Theme 4 – Safe versus basic sanitation: What is the difference between ‘basic’ and ‘safe’ sanitation? Why is this important? How do we ensure that we reach those most in need?
Leading the discussions, experts from the sector participating include amongst others:
- Ramisetty Murali, Convenor: Freshwater Action Network- South Asia (FANSA)
- Louisa Gosling, Programme Manager for Principles: WaterAid
- Graham Alabaster, Programme Manager: United Nations Human Settlements Programme (UN-HABITAT)
- Rose Osinde Alabaster, Operations Desk Officer: WaterLex
- Eddy Perez: Center for Global Safe Water, Sanitation and Hygiene at Emory University (Former Lead Sanitation Specialist, Water and Sanitation Program, World Bank)
- Tim Brewer, Policy Analyst: WaterAid
- Martin Gambrill: Lead Water and Sanitation Specialist, Water and Sanitation Program, World Bank
- Hanna Woodburn: Global Public Private Partnership for Handwashing
On the SuSanA Forum, regular summaries of the discussion will be posted. A summary report of each topic, along with an overview synthesis of all issues from the discussion, will be available in late September on the End Water Poverty and SuSanA Forum Websites.

WHO strengthens focus on water, sanitation and hygiene to accelerate elimination of neglected tropical diseases
August 27, 2015 – WHO strengthens focus on water, sanitation and hygiene to accelerate elimination of neglected tropical diseases | Source: World Health Organization
27 August 2015 –– The World Health Organization (WHO) today unveiled a global plan to better integrate water, sanitation and hygiene (WASH) services with four other public health interventions to accelerate progress in eliminating and eradicating neglected tropical diseases (NTDs) by 2020.
“Millions suffer from devastating WASH-related neglected tropical diseases – such as soil-transmitted helminthiasis, guinea-worm disease, trachoma and schistosomiasis – all of which affect mainly children” said Dr Maria Neira, WHO Director for Public Health, Environmental and Social Determinants of Health. “Solutions exist, such as access to safe water, managing human excreta, improving hygiene, and enhancing targeted environmental management. Such improvements not only lead to improved health, but also reduce poverty.”

- WASH and NTD global strategy 2015-2020
- Read 10 facts about tackling NTDs with WASH
- Public health, environmental and social determinants of health
Targeted water and sanitation interventions are expected to bolster ongoing efforts in tackling 16 out of the 17 NTDs, which affect more than 1 billion of the world’s poorest and most vulnerable populations.
A recent report showed that in 2015 more than 660 million people did not have access to improved water sources. The WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation report also showed that almost 2.5 billion people lacked access to improved sanitation. Open defecation and lack of hygiene are also an important risk factors for the transmission of many NTDs. Over half a million lives are lost each year as a result of NTDs.
“Joint planning, resourcing and delivery of WASH interventions are key to eliminating neglected tropical diseases and in achieving many public health and human development goals” said Dr Dirk Engels, Director of the Department of Control of Neglected Tropical Diseases. “The benefits are enormous – from alleviation of suffering through improved outcomes to healthier, wealthier and happier families, communities and nations.”

Whether it be washing hands with soap, driving sanitation demand, or purifying water, almost every area of public health requires behaviour change. The field of behaviour change is transforming.
There is a growing evidence base to suggest that traditional health education messages are insufficient to achieve sustained change and that more might be achieved by being more creative, for example by learning from product marketing, psychology and behavioural economics.
The ‘Creativity in Behaviour Change Symposium‘ will bring together behaviour change practitioners from academia, government and the private sector with the ambition of sparking an ongoing network of collaborators.
In addition to creative case studies and provocative discussions the event will feature interactive activities throughout the day, a ‘behaviour change cinema’ which will screen materials from creative projects from around the globe and there will be a ‘soap box’ where anyone can share their big ideas for the future of behaviour change.
For those who are not in the UK, all the sessions will also be filmed and available on our website at ehg.lshtm.ac.uk

To help us understand the WASH innovation ecosystem, we use two main conceptual frameworks. The first is an idealized model of the system dynamics of innovation, identifying the different stages and activities typically involved in innovation (recognition of need, generation of new ideas, creation of plausible inventions and solutions, development and implementation of potential innovations, and diffusion of innovations). The second, which we refer to as the Rs framework, seeks to uncover the detailed factors influencing how this system operates using the following headings: resources, roles, relationships, rules, routines, and results.

How can mobile channels can support sanitation service delivery while building new engagement models with customers in underserved settings? A new report  by the GSMA Mobile for Development Utilities Programme reviews opportunities and case studies.
The report begins with an overview of global sanitation access in 2015 and the different approaches currently being used to improve access. This is followed by a review of the potential uses of mobile channels in the sanitation value chain including examples of current applications.
The report concludes with recommendations for future work: a better understanding of the role and impact of mobile in the sanitation sector; a collaborative approach to mobile technology integration; grant support for developing and piloting innovative solutions; and rigorous monitoring and evaluation of the impact of these innovations in the service delivery.
An annex provides three short case studies on sanitation organisations currently using mobile tools in their service delivery model:
- SOIL, Haiti – mobile customer relationship management (CRM) platforms and mobile customer payments
- X-Runner, Peru – mobile CRM platforms and mobile for logistic solutions
- IDE Cambodia – mobile CRM and supply chain management (SCM) platforms for local entrepreneurs

Now available on WSUP-website for free download: masters-level professional training module “Water and Sanitation for Urban Low-Income Communities”
WSUP/WEDC have developed a teaching resource on urban WASH that is now available online for free, It aims at helping the urban WASH sector to professionalize. We hope it will be for academics and practitioners to use or adapt if they feel it can be of value to them.
In short: this is a masters-level professional training module called “Water and Sanitation for Urban Low-Income Communities”. It was primarily designed to give engineering masters students in low-income countries an overview of things they need to know in order to apply their technical skills in low-income communities, and that’s how WSUP and WEDC are currently using it, in partnership with universities in Africa and Asia. But of course it may be adaptable to other teaching contexts.
It’s designed for classroom delivery, over about 45 hours of contact time. It’s made up of 16 thematic units, and within each unit the materials essentially comprise a Powerpoint presentation plus Lecturer Notes outlining the unit’s aims and content, and providing guidance on how to deliver the class. Some units are flexible in content, to enable adaptation to local contexts.
It can be delivered as an off-the shelf package; or you might want to cut-and-paste parts of it into your own materials; or you might simply use it as guidance in developing other materials.
It’s absolutely free to download, but we do ask that you fill in a brief Use Request Form explaining who you are and how you might use it: evidently, it’s useful for us to be able to communicate this to the funder of the work (DFID).
For information, we expect to have a French-language version available within the next few months.
The module was developed by (alphabetical order): Louise Medland, Guy Norman, Brian Reed, Pippa Scott, Regine Skarubowiz, and Ian Smout; inputs also came from Richard Franceys and Valentina Zuin.

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.
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.
Assessment of water, sanitation, and hygiene practices and associated factors in a Buruli ulcer endemic district in Benin (West Africa). BMC Public Health, Aug 2015.
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.
Country characteristics and acute diarrhea in children from developing nations: a multilevel study. BMC Public Health, Aug 2015. Authors: Ángela María Pinzón-Rondón, et al.
The household characteristics associated with diarrhea in this study were as follows. (1) Number of household members: This was associated with diarrhea on bivariate correlation but not on the multivariable model, probably due to other household conditions included in the present study that may be associated with overcrowding. (2) Type of residence: Bivariate correlation showed that children from rural areas were more likely to present with diarrhea, as described previously in the literature . This association disappeared on multivariable models, probably due to the introduction of household wealth in the multivariable models. (3) Nuclear families: Children from nuclear families had 5 % smaller odds of developing diarrhea than did children from non-nuclear families. This outcome is probably secondary to the described effect of social stability that a nuclear family structure has on child health .

It has been estimated that approximately 88 % of diarrhea-induced deaths in the world are attributable to inadequate water supplies, poor hygiene and unsanitary conditions .
Water Quality Awareness and Breastfeeding: Evidence of Health Behavior Change in Bangladesh, June 2015. Author: Pinar Keskin, et al.
Decades of nation-wide campaigns regarding water safety in Bangladesh have cautioned households about the dangers of water-borne diseases from surface water and, more recently, arsenic contamination from certain tubewells. In addition to switching to uncontaminated well water, mothers can also protect their young children by breastfeeding longer. We study whether mothers modify their behavior in response. We exploit geographic variation in exposure to arsenic and time variation in whether children were born before or after the most recent campaign. In addition, we exploit geographic variation in the cost of switching to an arsenic-free well, namely the distance to nearby uncontaminated wells. We find that mothers breastfeed their children longer in contaminated areas and that this change is driven by households that have less access to clean wells. We also find that very young children in contaminated areas are more likely to be exclusively breastfed. This behavior change is consistent with the separate spheres model of intra-household bargaining where men have authority over certain decisions (which well to use), but women are able to influence other decisions (how to feed their children). Consistent with this breastfeeding response, we find suggestive evidence of relatively lower mortality rates and incidence of diarrhea for infants in more contaminated areas.

Analysis of Behavioral Change Techniques in Community-Led Total Sanitation Programs. Health Promot Int, Mar 2015. R Sigler. Abstract
The aims of this study are to (i) show which behavior change frameworks and techniques are the most common in CLTS interventions; (ii) describe how activities are implemented in CLTS interventions by region and context; and (3) determine which activities program implementers considered the most valuable in achieving open defecation free (ODF) status and sustaining it. The results indicate that a wide range of activities are conducted across the different programs and often go beyond standard CLTS activities.
CLTS in Fragile and Insecure Contexts: Experience from Somalia and South Sudan, 2014. UNICEF. Link
CLTS has been very successful in Somalia and South Sudan: Somalia has gone from zero ODF (Open Defecation Free) villages to 144 (self declared) ODF villages in 2 years and South Sudan declared 103 communities, 200,000 people in ODF communities in 2 years. CLTS is ideally suited for situations where access for aid workers is constrained since much of the action is community initiated rather than aid agency delivered.

OPEN DEFECATION STUDIES
Are Burial or Disposal with Garbage Safe Forms of Child Faeces Disposal? An Expert Consultation. Waterlines, July 2015. R Bain. Link
The importance of safe handling and disposal of child feces given its potential role in disease transmission are increasingly recognized. Household surveys demonstrate that the burying of child feces (‘dig-and-bury’) is common in several countries, especially in sub-Saharan Africa and South-east Asia. Disposal with garbage is widely practiced in middle- and high-income countries and is becoming increasingly common in urban areas of low-income countries. The safety of these two approaches is difficult to assess given the limited evidence available.
Management of Child Feces: Current Disposal Practices, 2015. E Rand. Link
Safe disposal of children’s feces is as essential as that of adults’ feces. Sanitation estimates are based on the household’s primary sanitation facility, and may overlook the disposal practices of young children feces. In many cases, children may not be able to use an improved toilet or latrine because of their age and stage of physical development or the safety concerns of their caregivers, even if their household has access to one.
Sanitation, Disease, and Anemia: Evidence From Nepal, 2015. D Coffey. Link
This paper is the first to propose the hypothesis that poor sanitation, a public good with other well-documented health externalities, significantly contributes to hemoglobin deficiency via its role in creating a poor disease environment. Researchers show that within regions over time, cohorts of children exposed to worse community sanitation developed lower hemoglobin levels and displayed higher anemia incidence. The results contribute to the basic science of anemia’s causes and suggest the possibility of new policy tools for reducing anemia in the developing world.

This study provides the first evidence that poor sanitation is associated with a higher risk of Adverse Pregnancy Outcomes (APOs). While it is intuitive to expect that caste and poverty are associated with poor sanitation practice driving APOs, and additional confounders cannot be ruled out, results demonstrate that the association of poor sanitation practices (open defecation) with these outcomes is independent of poverty. Results support the need to assess the mechanisms, both biological and behavioral, by which limited access to improved sanitation leads to APOs.

Are burial or disposal with garbage safe forms of child faeces disposal? An expert consultation. Waterlines, July 2015.
The importance of safe handling and disposal of child faeces given its potential role in disease transmission are increasingly recognized. Household surveys demonstrate that the burying of child faeces (‘dig-and-bury’) is common in several countries, especially in sub-Saharan Africa and South-east Asia. Disposal with garbage is widely practised in middle- and high-income countries and is becoming increasingly common in urban areas of low-income countries.
The safety of these two approaches is difficult to assess given the limited evidence available and we therefore sought the opinion of experts in the field of sanitation to support advocacy around the topic. We report the findings of an anonymous expert (Delphi) consultation on the safety of these two child faeces disposal methods. There was almost unanimous agreement these should be considered neither safe nor improved.
A range of arguments was provided to support this position, including proximity of solid waste and burial sites to the home and children’s play areas and that neither practice would be acceptable for adults. The consultation also highlighted gaps in the current evidence base that should be addressed to gain a fuller insight into the risks involved in these two forms of sanitation with a view to providing both programmatic and normative guidance.
In particular further work is needed to assess the potential for exposure to faecal matter in solid waste in low- and middle-income countries and to elucidate the predominant practices of child faeces burial including proximity to the home or infant play areas as well as depth of burial.

The HandyPod: sanitation for floating communities in Cambodia | Source: WaterAid, July 2015 |
Building safe and sustainable sanitation systems is a huge challenge for many poor communities, but when homes are built over water a new dimension is added. James Wicken, WaterAid Country Representative for Cambodia, looks at a new solution to the problem faced by Cambodia’s floating villages.A challenging environment for sanitation
For Cambodia to reach the Government’s target of universal access to sanitation by 2025, people living in these types of areas need sustainable solutions. In Cambodia, an estimated 25-45% of the population lives in ‘challenging environments’ such as floating villages. It is often the poorest people who can’t afford to own land who live in such places, and these populations are expected to grow, especially in cities as poor people continue to migrate. Cambodia is not alone – these informal settlements are found in many countries, such as Myanmar, Malaysia, Nigeria and Indonesia.
Because of WaterAid’s focus on equity and inclusion, these populations came on to our radar in our first year of work in Cambodia. WaterAid is partnering with a social enterprise calledWetlands Work! to test one potential solution – called the HandyPod – on the Tonlé Sap lake.
When people living in the lake’s floating villages – who number well over 100,000 – need to go to the toilet, they take a boat to a secluded spot on the lake, go into the surrounding forest, or at night may squat off the side of their floating house. This same water around the houses is used to wash dishes and clothes. Young children swim in it.Introducing: the HandyPod
The HandyPod took Wetlands Work! years to design, test and redesign. Resembling a floating garden, or a child’s paddling pool with a garden in it, it contains a man-made wetland filled with water hyacinths.
In the system, a normal porcelain squat toilet on the back of a floating house connects to a drum where the anaerobic (oxygen-less) processes take place. From here, the waste passes through to the HandyPod floating nearby, where the roots of water hyacinths further break down the waste before it passes into the lake. Wetlands Work! regularly collects water samples in the area around the pods, to ensure the quality conforms to Cambodian standards.

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.
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.
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.
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.
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.
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
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.

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.

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.

Anaerobic digestion is an efficient and renewable energy technology that can produce biogas from a variety of biomasses such as animal manure, food waste, and plant residues. In developing countries, this technology is widely used for the production of biogas using local biomasses, but there is little information about the value of these biomasses for energy production. This study was carried out with the objective of estimating the biogas production potential of typical Vietnamese biomasses such as animal manure, slaughterhouse waste, and plant residues.
ENVIRONMENTAL HEALTH IMPACTS
Human Diarrhea Infections Associated with Domestic Animal Husbandry: A Systematic Review and Meta-Analysis. Trans R Soc Trop Med Hyg, Mar 2014. L Zambrano. Link
Domestic animal husbandry, a common practice globally, can lead to zoonotic transmission of enteric pathogens. However, this risk has received little attention to date. This systematic review and meta-analysis examines the evidence for an association between domestic exposure to food-producing animals and cases of human diarrhea and specific enteric infections. Results suggest that domestic poultry and livestock exposures are associated with diarrheal illness in humans. Failure to ascertain the microbial cause of disease may mask this effect. Exposure to domestic animals should be considered a risk factor for human diarrheal illness and additional studies may identify potential mitigation strategies to address this risk.

Status of Taenia solium cysticercosis and Predisposing Factors in Developing Countries Involved in Pig Farming. Int J One Health, Jan 2015. J Kungu. Link
Taenia solium cysticercosis is a disease of pig and human populations considered endemic in many developing countries in Latin America, Africa, and South East Asia, that has a serious impact on public health and agriculture. Poor pig production practices, poor hygiene, and sanitation habits have been important in the maintenance of the T. solium life-cycle. The major gaps identified in this review include current information on PC prevalence in pigs with few reports on the condition in humans in most developing countries.
Occurrence of Porcine Cysticercosis in Free-Ranging Pigs Delivered to Slaughter Points in Arapai, Soroti District, Uganda. Onderstepoort J Vet Res. 2015 Jun. Link
Poverty, hunger and the need for production of pigs with meagre or zero inputs have made most farmers release their pigs to range freely, thus creating a pig-human cycle that maintains Taenia solium, the pig tapeworm and cause of porcine cysticercosis, in the ecosystem. A preliminary study was designed to establish the prevalence of porcine cysticercosis by postmortem examination of the tongue and carcass of free-range pigs from February to April 2014 in Arapai subcounty, Soroti district, eastern Uganda. Out of 178 pigs examined, 32 were qualitatively positive for porcine cysticercosis, representing a prevalence of 18.0%. This high prevalence represents a marked risk to the communities in the study area of neurocysticercosis, a debilitating parasitic zoonosis. Proper human waste disposal by use of pit latrines, confinement of free-range pigs and treatment with albendazole and oxfendazole are recommended.

Cysticercosis mainly affects the health and livelihoods of subsistence farming communities in developing countries of Africa, Asia, and Latin America. It also reduces the market value of pigs and cattle, and makes especially pork unsafe to eat. Cysticercosis is acquired when proglottids or eggs are ingested. It is a natural infection of pigs and cattle but, in the case of T. solium, it can also affect humans, usually when they swallow T. solium egg-contaminated soil, water or food (mainly vegetables). Taeniasis and cysticercosis are common in areas where animal husbandry practices are such that pigs and cattle come into contact with human feces.

The primary sources of FIB in the tropics (humans and livestock) all contribute to the dissemination of FIB at the soil surface in cultivated lands and inhabited areas via open air defecation and latrines, manure application and livestock. The primary sources also directly contaminate adjacent aquatic ecosystems via direct waste and wastewater release. In humid, tropical zones rain events are often characterized by high intensities and depth. During these events, contaminated soils are washed off in overland flow that contains high suspended sediment loads.

Hepatitis E is a virus mediated liver disease caused by hepatitis E virus (HEV). There are an estimated 3 million cases of acute HEV infection every year, causing 70,000 hepatitis E-related deaths worldwide. HEV is transmitted via the fecal-oral route. Contaminated water and food are main source of infection. Pigs, deer and other animal species may serve as a reservoir for HEV. This review highlights the current understanding of HEV infection in humans and animals.
Pathogen-Specific Burdens of Community Diarrhoea in Developing Countries: A Multisite Birth Cohort Study (MAL-ED). The Lancet, July 2015. J Platts-Mills. Link
Most studies of the causes of diarrhoea in low-income and middle-income countries have looked at severe disease in people presenting for care, and there are few estimates of pathogen-specific diarrhea burdens in the community. There was substantial heterogeneity in pathogen-specifi c burdens of diarrhoea, with important determinants including age, geography, season, rotavirus vaccine usage, and symptoms. Findings suggest that although single-pathogen strategies have an important role in the reduction of the burden of severe diarrheal disease, the effect of such interventions on total diarrheal incidence at the community level might be limited.

Campylobacteriosis is a zoonotic disease which has a worldwide public health impact. The disease is endemic in Egypt; however, the epidemiology in animals and humans has not been fully characterized. The objective of this study was to compare the risk of Campylobacter fecal carriage in children exposed to Campylobacter-infected vs. non-infected backyard poultry and to identify risk factors for a backyard being classified as infected. Backyard poultry may present a transmission route of C. jejuni to children. Backyards with poor cleaning and disinfection, wet litter and manure disposed of within the backyard had increased odds of being positive for C. jejuni.
Ghana – Drinking Water from Dug Wells in Rural Ghana — Salmonella Contamination, Environmental Factors, and Genotypes. Int. J. Environ. Res. Public Health, 12(4) 2015. D Dekker. Link
The study results provide an overview of the level of contamination in wells with Gram-negative rod-shaped bacteria and on the presence of unusual Salmonella serovars seen infrequently in patients but more often in reptiles and poultry. Studying animal reservoirs would provide useful information to identify the source of such contaminations.
India – Cryptosporidium and Giardia in Humans, Domestic Animals, and Village Water Sources in Rural India. Am Jnl Trop Med Hyg, June 2015. M Daniels. Link
Cryptosporidium parvum and Giardia lamblia are zoonotic enteric protozoa of significant health concern where sanitation, hygiene, and water supplies are inadequate. Animal loading estimates indicate the greatest contributors of environmental oocysts/cysts in the study region are cattle. Ponds were contaminated with both protozoa, as were tube wells. Future research should address the public health concern highlighted from these findings and investigate the role of domestic animals in diarrheal disease transmission in this and similar settings.
India – Human and Animal Fecal Contamination of Community Water Sources, Stored Drinking Water and Hands in Rural India Measured with Validated Microbial Source Tracking Assays. Am Jnl Trop Med Hyg, July 2015. A Schriewer. Link
This study confirms an often suggested contamination link from hands to stored water in the home in developing countries separately for mothers’ and children’s hands and both human and animal fecal contamination. In contrast to MST markers, FCs provided a poor metric to assess risks of exposure to fecal contamination of human origin in this rural setting.
Latin America – Cysticercosis Burden of Disease in Latín America, 2015. J Torres. Link
Cysticercosis is caused by infection with the larval form (or cysticercus) of the tapeworm Taenia solium. The most important clinical manifestations are caused by cysts in invading the central nervous system known as neurocysticercosis, which is associated with significant morbidity and disability in Latin America. Taeniasis and cysticercosis occur globally, with the highest rates in areas of Latin America, Asia, and sub-Saharan Africa associated with poor sanitation and free-ranging pigs with access to human feces.
Madagascar – Complex Epidemiology and Zoonotic Potential for Cryptosporidium suis in Rural Madagascar. Veterinary Parasitology, 207 2015. J Bofager. Link
In this study system. Interestingly, C. suis was the dominant species of Cryptosporidium in the region, infecting humans, cattle, pigs, and rodents. This report represents the fifth confirmed case of C. suis infection in humans, and the first case in Africa. Few rural human and livestock populations have been screened for Cryptosporidium using genus-specific genotyping methods. Consequently, C. suis may be more widespread in human and cattle populations than previously believed.
Nepal – Cryptosporidium Infection Among the School Children of Kathmandu Valley.Journal of Institute of Medicine, Apr, 2015. D Bhandari. Link
The detection of Cryptosporidium oocysts and observance of diarrheal symptoms, together with the pattern of age-specific occurrence, livestock presence at home, consumption of untreated drinking water and raw vegetables/fruits consumption habit among infected children suggest that in low-income Kathmandu communities, cryptosporidiosis coupled with poor sanitary practice is a public-health issue causing potentially serious consequences.
Zambia – Why Latrines Are Not Used: Communities’ Perceptions and Practices Regarding Latrines in a Taenia solium Endemic Rural Area in Eastern Zambia. PLoS Negl Trop Dis, Mar 2015. S Thys. Link
Taenia solium cysticercosis is a neglected parasitic zoonosis occurring in many developing countries. Socio-cultural determinants related to its control remain unclear. Studies in Africa have shown that the underuse of sanitary facilities and the widespread occurrence of free-roaming pigs are the major risk factors for porcine cysticercosis. The study objective was to assess the communities’ perceptions, practices and knowledge regarding latrines in a T. solium endemic rural area in Eastern Zambia inhabited by the Nsenga ethno-linguistic group, and to identify possible barriers to their construction and use.
