Behaviour change intervention to improve shared toilet maintenance and cleanliness in urban slums of Dhaka: a cluster-randomised controlled trial. TMIH, August 2017. (ABSTRACT/ORDER) In one of few efforts to promote shared toilet cleanliness, intervention compounds were significantly more likely to have cleaner toilets after six months. Future research might explore how residents can self-finance toilet maintenance, or employ mass media to reduce per-capita costs of behaviour change.

Water works: how a simple technology in Dhaka is changing the way people get clean water. Water Blog, July 27. Amy Pickering of Tufts University discusses a novel treatment product that automatically dispenses small amounts of chlorine to create safe drinking water.

Identifying Potential Sources of Exposure Along the Child Feces Management Pathway: A Cross-Sectional Study Among Urban Slums in Odisha, India. AJTMH, July 24, 2017. While proper disposal of child feces in an improved latrine still represents a major challenge, control of the risks presented requires attention to the full range of exposures associated to the management of child feces, and not simply the place of disposal.

This paper aims to highlight the key vaginal bleeding experiences throughout a woman’s life course and the intersection of these bleeding experiences with their access to adequate water and sanitation facilities, information and education sources, and supplies.

Differences in Child Health across Rural, Urban, and Slum Areas: Evidence from India. Claus C Pörtner, June 2017. We estimate that slum conditions—which the survey does not adequately capture, such as overcrowding and open sewers—are associated with 20–37% of slum children’s stunting risk.

WASH articles from Environment & Urbanization

IIED’s Environment and Urbanization is a key journal for urban WASH studies. Below are links to the abstracts for the latest WASH-related articles.

ONLINE FIRST ARTICLES

Health and water quality benefits of alternative sewerage systems in Metro Manila, Philippines.
This paper presents results of a household survey on the current sanitation and sewerage conditions in Metro Manila. The survey included a choice, measured in terms of the marginal willingness to pay (MWTP), between two alternative domestic wastewater treatment systems: 1) a sewerage system connecting individual households to a treatment plant through sewer lines; and 2) a combined drainage–sewerage system in which wastewater effluent flows with rainwater through flood canals and is intercepted for treatment only at a certain point in the waterway. With the second, the health improvement effect may be limited, but the cost can be significantly lower. The finding in favour of the combined drainage–sewerage system lends some support to this new approach in municipal wastewater treatment, which some other increasingly congested metropolises in Asian countries are likewise adopting, as an alternative to the more costly individual household sewer connections.

Bathing without water, and other stories of everyday hygiene practices and risk perception in urban low-income areas: the case of Lilongwe, Malawi.
Hygiene plays a key role in tipping the balance towards reduction of diarrhoeal and other infectious diseases. Yet it has often been overlooked, positioned as a “supporting rider” of water supply and sanitation services, or narrowly understood as handwashing. By focusing on handwashing infrastructure as proposed for the monitoring of Sustainable Development Goal (SDG) 6, development actors might miss the opportunity of capturing hygiene practices that are socially embedded and can act as a catalyst for change and risk reduction. We develop this argument by presenting an in-depth examination of hygiene practices in a low-income neighbourhood of Lilongwe, Malawi. Despite the high poverty levels and the constant water shortages in the area, a number of water-intensive hygiene practices are consistently carried out, proving that hygiene is central to residents’ everyday lives. Development projects should start by identifying these practices and by reflecting on the extent that these already work or can be made to work for reducing health-related risks.

Beyond the networked city: situated practices of citizenship and grassroots agency in water infrastructure provision in the Chamazi settlement, Dar es Salaam.
This paper problematizes the liberal ideal of citizenship that, it is argued, limits active participation of poor communities in decision-making around basic urban infrastructure services and enjoyment of their citizenship rights. In place of liberal citizenship, the paper argues in favour of newly emerging forms of citizenship within participatory spheres that enhance access of the poor to urban services through direct participation aimed at socially equitable outcomes. Using the case of the Chamazi community water infrastructure initiative in Dar es Salaam, Tanzania, this paper demonstrates that community grassroots agency is capable of instigating institutional changes and brokering power in seeking social justice in infrastructure provision.
An assessment of the evolution of Kenya’s solid waste management policies and their implementation in Nairobi and Mombasa: analysis of policies and practices.
This paper provides a summary of the priorities and strategies stipulated by the major solid waste management (SWM) policies in Kenya. It also provides a brief assessment of their implementation in Nairobi and Mombasa, drawing on data from a 2016 community-based study. We found that SWM policies have evolved to specificity in terms of focus, functions and scope. There was a shift from criminalizing solid waste action or inaction to promoting good practices; from generic acts to specific ones; and from centralized mandates to more decentralized responsibilities. However, SWM remains a critical concern and a major challenge in Nairobi and Mombasa as a result of weak institutional structures and capacity, weak enforcement of regulatory frameworks, and the control of the sector by criminal cartels.

Assessment of Fecal Exposure Pathways in Low-Income Urban Neighborhoods in Accra, Ghana: Rationale, Design, Methods, and Key Findings of the SaniPath Study. AJTMH, July 17, 2017.
The study results highlight widespread and often high levels of fecal contamination in the public and private domains and food supply. The dominant fecal exposure pathway for young children in the household was through consumption of uncooked produce. The SaniPath Study provides critical information on exposure to fecal contamination in low-income, urban environments and ultimately can inform investments and policies to reduce these public health risks.

Women still carry most of the world’s water. The Conversation, July 16, 2017.
In this article, Bethany Caruso of Emory University discusses her research in India, Bolivia and Kenya on the water and sanitation challenges that women and girls confront and how these experiences influence their lives.

Decision-making on shared sanitation in the informal settlements of Kisumu, Kenya. International Journal of Environmental Health Research, July 13, 2017.
Using a grounded theory approach, landlords and tenants were interviewed to identify sanitation decisions, individuals involved in decision-making and factors influencing decision-making. The results indicate that the main sanitation decisions are on investment, emptying, repair and cleaning. Sanitation interventions in informal settlements should thus, target landlords and tenants, with investment efforts being directed at landlords and maintenance efforts at tenants.

ABSTRACT/ORDER

The effect of young children’s faeces disposal practices on child growth: Evidence from 34 countries. TMIH, July 16, 2017.
Improved child faeces disposal practices could achieve greater reductions in child undernutrition than improving toilet access alone. Additionally, the common classification of child faeces disposal as ‘safe’ regardless of the type of toilet used for disposal may underestimate the benefits of disposal in an improved toilet and overestimate the benefits of disposal in an unimproved toilet.

Open defecation explains differences in nutritional status between Bengali and tribal children in the Chittagong Hill Tracts of Bangladesh. Ethnicity & Health, July 1, 2017.
We describe differences in linear growth as measured by height-for-age z-score (HAZ) between children from Bengali and tribal populations in the Chittagong Hill Tracts of Bangladesh and examine factors associated with HAZ in both groups. Different responses among Bengali and tribal children to village-level open defecation are an explanatory factor for the difference in HAZ between Bengali and tribal populations. Open defecation may also act a proxy for unmeasured factors such as household environmental conditions and food hygiene.
