Product Design Supporting Improved Water, Sanitation, and Energy Services Delivery in Low-Income Settings. Sustainability, November 2019. Several approaches have been proposed in the literature supporting product design applied in low-income settings. These approaches have typically focused on individual- and household-level beneficiaries, with an emphasis on participatory, human-centered co-design methods. In this paper, we present a design approach that is, in contrast, focused on supporting providers of improved water, sanitation, and energy services.

IDS SANITATION RESEARCH

Who is being left behind in Swachh Bharat Mission? How do we include them? Immersive research report by WaterAid India with Institute of Development Studies, gives insight into who is missed in sanitation programming in areas of India and how to include them. podcast

‘More or less: A rapid review of ‘water for toilets’ in rural India’, examines both technical and behavioural aspects surrounding water collection, management and consumption related to toilet use in rural India. It provides recommendations for steps forward.

Retrofitting of toilets is a complex and challenging stream of work and is included as one of the main components of Open Defecation Free-Sustainability (ODF-S) plans under Swachh Bharat Mission- Gramin (SBM-G). This rapid topic review ‘Retrofitting: The Next Step for the Swachh Bharat Mission?’ aims to provide recent evidence and insights into the scale and nature of the challenges of retrofitting.

PEER RESEARCH PROPOSALS

School-based, blacklight handwashing program can improve handwashing quality and knowledge among pre-school aged children. Evaluation and Program Planning, February 2020. Authors: Deirdre Dingman, Jingwei Wub, Heather M.Murphy – Puzzles and structured handwashing observations can be used as handwashing evaluation tools. Use of a black light technology as an educational tool can help to improve handwashing quality among pre-school aged children.

Impact of the “BALatrine” Intervention on Soil-Transmitted Helminth Infections in Central Java, Indonesia: A Pilot Study. Trop. Med. Infect. Dis., Dec 2019. We tested a low-cost, locally designed and constructed all-weather latrine (the “BALatrine”), together with community education promoting appropriate hygiene-related behaviour, to determine whether this integrated intervention effectively controlled soil-transmitted helminth (STH) infections.

Relationship of sanitation, water boiling, and mosquito nets to health biomarkers in a rural subsistence population. Am Jnl Human Biology, Dec 2019. This suggests that relatively low cost and low maintenance public health interventions may wish to focus on latrine use, as there is unmet need and potential health benefits for those who use latrines. Additionally, while the cost is higher, public health organizations aimed at improving sanitation may be able to use minimally invasive field‐collected biomarkers as a diagnostic to objectively test the efficacy of interventions with greater specificity than anthropometric measurements.

Citywide Inclusive Sanitation through Scheduled Desludging Services: Emerging Experience from India. Front. Environ. Sci., 27 November 2019. This paper first reviews the need for regular desludging of septic tanks. It then outlines the emerging experience of design and implementation of scheduled desludging for inclusive, equitable, and sustainable sanitation to achieve social and environmental benefits in two Indian cities. In these cities, a performance-linked annuity payment framework is used to engage a private desludging enterprise. Payment is met through a sanitation tax and transfer from the general property taxes.

Infant Food Hygiene and Childcare Practices in Context: Findings from an Urban Informal Settlement in Kenya. The American Society of Tropical Medicine and Hygiene, November 18, 2019. Authors: Jane Awiti, Odhiambo Mumma, Oliver Cumming, Sheillah Simiyu, Alexandra Czerniewska, Rose Evalyne Aseyo, Damaris Nelima Muganda, Emily Davis, Kelly K. Baker and Robert Dreibelbis – Our findings demonstrate that behaviors associated with food contamination, such as hand feeding and storing food for extended periods, are determined largely by the larger social and economic realities of primary caretakers. Data also show how caregiving within an informal settlement is highly dynamic and involves multiple individuals and locations throughout the day.

Implications of recent WASH and nutrition studies for WASH policy and practice – WHO/UNICEF position paper

Implications of recent WASH and nutrition studies for WASH policy and practice – WHO/UNICEF position paper, November 2019. Children wash their hands outside school in Samabogo, Mali.

The WHO/UNICEF position paper summarizes the studies, contextualizes the findings within the wider body of evidence and distills the implications for future investments. The paper is accompanied by a recorded interview with the heads of WASH for WHO and UNICEF and the lead author of a consensus statement from leading researchers.

An excerpt – What are the implications for WASH programming?

The findings of WASH Benefits and SHINE are not a reason to do less on WASH. Conversely, the historical significance of WASH in disease control, the strong conceptual basis for WASH (Box 2) and the need for WASH to reduce the potential for outbreaks in addition to breaking endemic transmission all indicate that the WASH sector collectively needs to do more and better to reach the ambitious targets of the SDGs.

The findings also highlight blind spots in typical WASH programming – particularly the role of animal waste and fecal contamination of food during irrigation and food preparation that are often overlooked in WASH programme design.

Many have called for transformative WASH In response to the studies but with some ambiguity around what is meant. While the consensus is that this implies interventions that lead to a comprehensively clean environment (Box 1), the path to this result is not universally agreed.
