Assessing equity: a way to improve sanitation service delivery in South African informal settlements

Assessing equity: a way to improve sanitation service delivery in South African informal settlements. Journal of Water, Sanitation and Hygiene for Development, September 2018.

This paper discusses the need to incorporate equity assessment into the planning and monitoring of sanitation service delivery to South African informal settlements. Equity assessment criteria were drawn from literature and a study of sanitation service delivery to informal settlements in three South African municipalities (Cape Town, Johannesburg and eThekwini) over the period 2012–2015. wash

Three key dimensions of equity – resource allocation, access and stakeholder perceptions – were identified. These had eight associated criteria: (1) funds allocated for basic sanitation, (2) number of staff allocated to informal settlements, (3) disparities in access, (4) proportion of functioning sanitation facilities, (5) menstrual hygiene management (MHM) inclusion, (6) access to information, (7) meets users’ notions of dignity, and (8) integration of the perspectives of key stakeholders.

Key findings of the study indicate that the current focus on reducing service backlogs largely ignores equity and there is a need to better address this through the incorporation of: equity assessments, improving access to information, and the inclusion of marginalised communities in the planning of sanitation services.

Mapping the evidence on WASH promotion in communities, schools and health facilities – 3ie Impact

Mapping the evidence on WASH promotion in communities, schools and health facilities. 3ie Impact, August 2018.  three

Highlights

  • The number of rigorous studies on WASH promotion in households, schools and communities has increased substantially.
  • Very few rigorous studies exist on WASH promotion in medical facilities.
  • Many new studies evaluate previously under-researched approaches, such as community-led total sanitation, and measure important sector outcomes, including school attendance and reducing open defecation.
  • More studies are needed to measure programme effects on the sustained use of technologies and slippage back to open defecation.
  • A critical need exists for studies on promotional approaches for vulnerable populations, especially people living with disabilities, for whom no studies are available. New, high-quality systematic reviews are available, including ones on the effectiveness of hygiene and sanitation behavioural approaches and menstrual hygiene management.
  • Synthesis gaps remain for high-quality reviews on WASH interventions in schools and on decentralised delivery

Child Height in India: Facts and Interpretations from the NFHS-4, 2015–16. Diane Coffey; Dean Spears, Aug 6. Factor (2)—the extent of open defecation—can be estimated using data from the NFHS-4. Coffey and Spears (2018) find that between the NFHS-3 and the NFHS-4, open defecation in India went down by 16.4 percentage points, from 55.3% to 38.9%. Combined with the Gertler et al (2015) effect estimate, this change in average exposure to open defecation would predict an increase in average height-for-age of 0.077 of a height-for-age standard deviation, due to improved sanitation.

Acceptability and Feasibility of Sharing a Soapy Water System for Handwashing in a Low-Income Urban Community in Dhaka, Bangladesh: A Qualitative Study. AJTMH, Aug 2018.
Soapy water was an acceptable hand cleaning agent, with the bottle as a feasible dispenser. It was simple in design, cost-effective, replicable, popular with intervention recipient, and neighboring nonrecipients, and commonly shared among nonrelated households. The need to share expenses and product preparation served as a barrier.

Recent research on sanitation,shared latrines, handwashing and other WASH issues

Below are links to an interesting report from the Rockefeller Foundation and other recently published journal articles and blogs:

Sanitation in the Context of Planetary Health: Opportunities and Challenges. Rockefeller Foundation, July 2018. Poor sanitation is a factor in an estimated 80% of all environment-related deaths. Poor sanitation costs countries between 0.5 and 7.2% of their annual GDP. The World Health Organization estimated total global economic losses to be US$260 billion annually in 2012. Investment in sanitation returns an estimated US$5-16 for every US$1 spen

Children Are Exposed to Fecal Contamination via Multiple Interconnected Pathways: A Network Model for Exposure Assessment. Risk Analysis, July 2018. This article describes a dynamic, multipathway exposure assessment model for children under five years of age in crowded, highly contaminated urban environments. Models of varying environmental concentrations of fecal microbes, child behaviors, and a comprehensive set of exposure factors were combined to simulate microbe transfer in a network structure from environmental sources to human ingestion.

Shared latrines in Maputo, Mozambique: exploring emotional well-being and psychosocial stress. BMC International Health and Human Rights, July 25.  Our data suggest that “improved”, shared facilities can reduce stress when proper maintenance and management systems are in place. Private, shared sanitation only had limited impact on users’ perceptions of safety, particularly at night, suggesting that safety concerns extend beyond the physical latrine structure. Our research demonstrates that factors including latrine location and neighborhood violence are important determinants of safety perceptions and corresponding psychosocial stress.

Water, sanitation, and hygiene practices mediate the association between women’s empowerment and child length‐for‐age z‐scores in Nepal. Maternal & Child Nutrition, 26 July 2018. Empowered women had better WASH practices than nonempowered women, which translated into higher child LAZ. Child DD was not a mediating factor in the association between women’s empowerment and child LAZ. More research is needed to explore other pathways by which women’s empowerment may affect child nutrition outcomes.

OPEN ACCESS JOURNAL ARTICLES

The global risks of increasing reliance on bottled water. Nature Sustainability, July 16.
The rapid growth of bottled water use in low- and middle-income countries, and its normalization as a daily source of drinking water, does not provide a pathway to universal access. Generous and sustained investment in centralized and community utilities remains the most viable means for achieving safe water access for all.

Intrinsic and Instrumental Perspectives to Sanitation. SSM – Population Health, 18 July.
But what is often overlooked is the fact that a given public health intervention might be the end in itself. In other words, a given intervention might be worth investing in even if there are zero returns from investing in it. This intrinsic value, however, is often overlooked. In this commentary, we look specifically at sanitation, and why the development community should motivate sanitation interventions using an intrinsic value perspective.

Socio-environmental drivers of sustainable adoption of household water treatment in developing countries. NPJ, July 23.
The objective of this study is to analyze the interactions between such socio-environmental characteristics, rather than a single characteristic, in order to explain the adoption of HWT. Five socio-environmental characteristics and behavior determinants were analyzed using Qualitative Comparative Analysis (QCA) from 41 case studies in Africa, Asia, and South America. Results show that there is no single characteristic that alone explains the adoption of HWT.
