Previous research has explored the contextual and programmatic factors that influence CLTS performance. Less is known about the community-level conditions that sustain latrine coverage and use. We hypothesized three categories of community conditions underlying CLTS sustainability: (i) engagement of community leaders, (ii) follow-up intensity, and (iii) support to poor households. We evaluated these among communities in Cambodia and Ghana, and applied fuzzy-set Qualitative Comparative Analysis (fsQCA) to identify combinations of conditions that influenced current latrine coverage and consistent latrine use. In Cambodia, latrine coverage was highest in communities with active commune-level leaders rather than traditional leaders, and with leaders who used casual approaches for promoting latrine construction. Latrine use in Cambodia was less consistent among communitie...

Community-Led Total Sanitation (CLTS) is the most widely deployed approach to generate demand for, and use of sanitation facilities. CLTS relies on behavioral change and community self-enforcement to end open defecation. Since its genesis in Bangladesh in 1999, CLTS has spread to approximately 60 countries, mostly in Asia and Africa, and is employed by the majority of development organizations operating in rural sanitation. This paper uses a qualitative approach to analyze the reasons and processes that drove the wide diffusion of CLTS. We show that CLTS was embraced because it was perceived as a fast and effective solution to the problem of open defecation, one which was in line with the decentralization and community participation paradigms, at a time when donors and governments were looking for strategies to meet the MDG for sanitation. CLTS spread under the leadership of influential donors, NGOs, persuasive practitioners, and academics. Face-to-face interactions among members of this network and local governments at conferences and workshops played a central role in the diffusion of the approach. The use of experiential learning during study tours and workshop field visits has been crucial to persuade government actors at different levels, NGOs, and donors to use the CLTS approach. Notably, robust scientific evidence played little role in the diffusion of CLTS. We conclude by making suggestions to strengthen the evidence base for rural sanitation policies.

The combination of a high faecal-related disease burden and inadequate infrastructure suggests that investment in expanding sanitation access in densely populated urban slums can yield important public health gains. No rigorous, controlled intervention studies have evaluated the health effects of decentralised (non-sewerage) sanitation in an informal urban setting, despite the role that such technologies will likely play in scaling up access. We have designed a controlled, before-and-after (CBA) trial to estimate the health impacts of an urban sanitation intervention in informal neighbourhoods of Maputo, Mozambique, including an assessment of whether exposures and health outcomes vary by localised population density. The intervention consists of private pour-flush latrines (to septic tank) shared by multiple households in compounds or household clusters. We ...

This study uses primary data collected from more than 200 resellers in Maputo, Mozambique, through in-person surveys, participant observation and focus group discussions. Despite the widely held assumption that all small-scale water providers are profit-maximizing entrepreneurs, this study suggests that this model does not characterize resale behavior in Maputo. Instead, three non-mutually exclusive motivations provide more persuasive explanations for why households resell utility water: (1) earning cash to meet daily subsistence needs; (2) obtaining a form of informal social insurance to deal with future needs; and (3) solidifying embeddedness in social relationships by satisfying the social norms of their communities. These findings suggest that programs and policie...

The paper aims at understanding the areas in which it was successful, and illustrate how - despite important shortcomings - the project has become to be considered exemplary. The paper first shows that the project is not as participatory as international donors believe. Moreover, it illustrates that project's sustainability is at risk because inter-governmental political competition between the state and municipal government and party politics prevented the inclusion of the Municipality- institution responsible for...

Piped water access in sub-Saharan Africa (SSA), however, is the lowest of all SDG regions and is declining: in 2017, only 56% of the urban population in SSA had access to piped water in their homes, down from 65% in 2000. Increasing water access via private connections is difficult for many of utility providers in SSA, and unconnected households may also choose not to connect to the water utility network because of low-quality utility service, high water charges and high connection fees. This paper focuses on understanding the impact of the pro-poor water reforms implemented between 2010 and 2019 in the Greater Maputo Area (GMA), Mozambique; specifically, it attempts to understand how households were able to obtain piped water access through a water connection campaign, a reduction of the connection fee, and the option of paying in instalments. We use data collected in 2010 and 2012 – before and after these ...

A non-governmental organization replaced existing poor-quality latrines with pour-flush toilets with septic tanks serving household clusters. We enrolled children aged 1–48 months at baseline and measured outcomes before and 12 and 24 months after the intervention, with concurrent measurement among children in a comparable control arm. Despite nearly exclusive use, we found no evidence that intervention affected the prevalence of any measured outcome after 12 or 24 months of exposure. Among children born into study sites after intervention, we observed a reduced prevalence of Trichuris and Shigella infection relative to the same age group at baseline (<2 years old). Protection from birth may be important to reduce exposure to and infectio...
