Is Community-Led Total Sanitation connected to the rebuilding of latrines? Quantitative evidence from Mozambique.

ABSTRACT: To reduce open defecation, many implementers use the intervention strategies of Community-Led Total Sanitation (CLTS). But CLTS focuses on latrine construction and does not include latrine maintenance and repair damage or collapse. Some households rebuild their latrine while others return to open defecation. The reasons why are unknown. Using data from a cross-sectional survey, this article shows how physical, personal, and social context factors and psychosocial factors from the RANAS model are associated with CLTS participation, and how these factors connect to latrine rebuilding. In 2015, heavy rains hit the north of Mozambique and many latrines collapsed. Subsequently, 640 household interviews were conducted in the affected region. Logistic regression and mediation analyses reveal that latrine rebuilding depends on education, soil conditions, social cohesion, and a feeling of being safe from diarrhea, the perception that many other community members own a latrine, and high confidence in personal ability to repair or rebuild a broken latrine. The effect of CLTS is mediated through social and psychosocial factors. CLTS already targets most of the relevant factors, but can still be improved by including activities that would focus on other factors not yet sufficiently addressed.

Project description:We conducted a study to evaluate the sustainability of community-led total sanitation (CLTS) outcomes in Ethiopia and Ghana. Plan International, with local actors, implemented four CLTS interventions from 2012 to 2014: health extension worker-facilitated CLTS and teacher-facilitated CLTS in Ethiopia, and NGO-facilitated CLTS with and without training for natural leaders in Ghana. We previously evaluated these interventions using survey data collected immediately after implementation ended, and concluded that in Ethiopia health extension workers were more effective facilitators than teachers, and that in Ghana training natural leaders improved CLTS outcomes. For this study, we resurveyed 3831 households one year after implementation ended, and analyzed latrine use and quality to assess post-intervention changes in sanitation outcomes, to determine if our original conclusions were robust. In one of four interventions evaluated (health extension worker-facilitated CLTS in Ethiopia), there was an 8 percentage point increase in open defecation in the year after implementation ended, challenging our prior conclusion on their effectiveness. For the other three interventions, the initial decreases in open defecation of 8-24 percentage points were sustained, with no significant changes occurring in the year after implementation. On average, latrines in Ethiopia were lower quality than those in Ghana. In the year following implementation, forty-five percent of households in Ethiopia repaired or rebuilt latrines that had become unusable, while only 6% did in Ghana possibly due to higher latrine quality. Across all four interventions and three survey rounds, most latrines remained unimproved. Regardless of the intervention, households in villages higher latrine use were more likely to have sustained latrine use, which together with the high latrine repair rates indicates a potential social norm. There are few studies that revisit villages after an initial evaluation to assess sustainability of sanitation outcomes. This study provides new evidence that CLTS outcomes can be sustained in the presence of training provided to local actors, and strengthens previous recommendations that CLTS is not appropriate in all settings and should be combined with efforts to address barriers households face to building higher quality latrines.

Project description:Every year, cholera affects 1.3-4.0 million people worldwide with a particularly high presence in Africa. Based on recent studies, effective targeting interventions in hotspots could eliminate up to 50% of cases in Sub-Saharan Africa. Those interventions include Water, Sanitation, and Hygiene (WASH) programs whose influence on cholera control, up to the present, has been poorly quantified. Among the few studies available, D'Mello-Guyett et al. underline how the distribution of hygiene kits is a promising form of intervention for cholera control and that the integration of a WASH intervention at the point of admission of suspected cases is new in cholera control efforts, particularly in outbreaks and complex emergencies. Considering the limited number of studies on Community-Led Total Sanitation (CLTS) and water coverages related to cholera control, the aim of our work is to determine whether these interventions in cholera hotspots (geographic areas vulnerable to disease transmission) have significant impact on cholera transmission. In this study, we consider data collected on 125 villages of the Madarounfa district (Niger) during the 2018 cholera outbreak. Using a hurdle model, our findings show that full access to improved sanitation significantly decreases the likelihood of cholera by 91% (P < 0.0001) compared to villages with no access to sanitation at all. Considering only the villages affected by cholera in the studied area, cholera cases decrease by a factor of 4.3 in those villages where there is partial access to at least quality water sources, while full access to improved water sources decreases the cholera cases by a factor of 6.3 when compared to villages without access to water (P < 0.001). In addition, villages without access to safe water and sanitation are 6.7 times (P < 0.0001) more likely to get cholera. Alternatively, villages with full sanitation and water coverage are 9.1 (P < 0.0001) less likely to get cholera. The findings of our study suggest that significant access to improved water and sanitation at the village level offer a strong barrier against cholera transmission. However, it requires full CLTS coverage of the village to observe a strong impact on cholera, as partial access only has a limited impact.

Project description:Based on the sustainable development goals, the United Nations plans to achieve equitable sanitation and hygiene for all and to end open defecation by 2030. In Ethiopia, 60% to 80% of health problems are due to communicable diseases attributable to unsafe water supply, unhygienic and unsanitary waste management, which are directly linked to the practice of open defecation. This study has aimed at assessing the implementation of community-led total sanitation and hygiene (CLTSH) and associated factors. A community-based cross-sectional study design involving 420 of the 7,225 households found in Diretiyara district was conducted in June 2014. Both quantitative and qualitative data were collected. Using Logistic Regressions, bivariate and multivariate analyses were computed. This study showed that 66% of the respondents have knowledge of CLTSH. Eighty-nine percent of the respondents have latrine, of which 78% were constructed after the introduction of CLTSH. Eleven percent of the respondents reported to have defected in the open field and 15% of them reported that they had been recently exposed to diarrhea diseases. The occurrence of diarrheal disease was significantly associated with the extent of latrine ownership [AOR = 2.48; 95% CI 1.00, 6.12]. Attitude and perception parameters were significantly associated with consistent latrine utilization. Respondents who agreed that "Open defecation is preferred due to the unpleasant smell and heat from the Latrine'' [COR = 0.58; 95% CI 0.34, 0.99] were 58% less likely to use the latrine consistently. In conclusion, CLTSH has increased the extent of latrine ownership and decreased practice of open defecation, and yet, intermittent latrine use and poor hygienic practice were reported. Although some fundamental misconceptions were reported, the majority of the respondents have accepted CLTSH approach as a means to ending open defecation in their village. Health extension workers and local authorities should give emphasis to achieving sustainable behavioral change on improved sanitation and good hygiene practices.
