Risk Perceptions of Wastewater Use for Urban Agriculture in Accra, Ghana.

ABSTRACT: Poor food hygiene is a significant risk to public health globally, but especially in low and middle-income countries where access to sanitation, and general hygiene remain poor. Food hygiene becomes even more pertinent when untreated, or poorly treated wastewater is used in agriculture. In such circumstances the WHO recommends the adoption of a multiple-barrier approach that prescribes health protective measures at different entry points along the food chain. This study sought to assess the knowledge and awareness of wastewater use for crop production, its related health risks, and adoption of health protective measures by farmers, market salespersons and consumers using questionnaires and focus group discussions. In the period from September 2012 to August 2013, 490 respondents were interviewed during two cropping seasons. The study found that awareness of the source of irrigation water was low among consumers and street food vendors, though higher among market vendors. In contrast, health risk awareness was generally high among salespersons and consumers, but low among farmers. The study found that consumers did not prioritize health indicators when buying produce from vendors but were motivated to buy produce, or prepared food based on taste, friendship, cost, convenience and freshness of produce. Similarly, farmers' awareness of health risk did not influence their adoption of safer farm practices. The study recommends the promotion of interventions that would result in more direct benefits to both producers and vendors, together with hygiene education and enforcement of food safety byelaws in order to influence behaviour change, and increase the uptake of the multiple-barrier approach.

Project description:BackgroundMental health disorders present significant health challenges in populations in sub Saharan Africa especially in deprived urban poor contexts. Some studies have suggested that in collectivistic societies such as most African societies people can draw on social capital to attenuate the effect of community stressors on their mental health. Global studies suggest the effect of social capital on mental disorders such as psychological distress is mixed, and emerging studies on the psychosocial characteristics of collectivistic societies suggest that mistrust and suspicion sometimes deprive people of the benefit of social capital. In this study, we argue that trust which is often measured as a component of social capital has a more direct effect on reducing community stressors in such deprived communities.MethodsData from the Urban Health and Poverty Survey (EDULINK Wave III) survey were used. The survey was conducted in 2013 in three urban poor communities in Accra: Agbogbloshie, James Town and Ussher Town. Psychological distress was measured with a symptomatic wellbeing scale. Participants' perceptions of their neighbours' willingness to trust, protect and assist others was used to measure community sense of trust. Participants' willingness to ask for and receive help from neighbours was used to measure personal sense of trust. Demographic factors were controlled for. The data were analyzed using descriptive and multivariate regressions.ResultsThe mean level of psychological distress among the residents was 25.5 (SD 5.5). Personal sense of trust was 8.2 (SD 2.0), and that of community sense of trust was 7.5 (SD 2.8). While community level trust was not significant, personal sense of trust significantly reduced psychological distress (B = -.2016728, t = -2.59, p < 0.010). The other factors associated with psychological distress in this model were perceived economic standing, education and locality of residence.ConclusionThis study presents evidence that more trusting individuals are significantly less likely to be psychologically distressed within deprived urban communities in Accra. Positive intra and inter individual level variables such as personal level trust and perceived relative economic standing significantly attenuated the effect of psychological distress in communities with high level neighbourhood disorder in Accra.

Project description:Exposure to fecal contamination in public areas, especially in dense, urban environments, may significantly contribute to enteric infection risk. This study examined associations between sanitation and fecal contamination in public environments in four low-income neighborhoods in Accra, Ghana. Soil (n = 72) and open drain (n = 90) samples were tested for E. coli, adenovirus, and norovirus. Sanitation facilities in surveyed households (n = 793) were categorized by onsite fecal sludge containment ("contained" vs. "uncontained") using previous Joint Monitoring Program infrastructure guidelines. Most sanitation facilities were shared by multiple households. Associations between spatial clustering of household sanitation coverage and fecal contamination were examined, controlling for neighborhood and population density (measured as enumeration areas in the 2010 census and spatially matched to sample locations). E. coli concentrations in drains within 50m of clusters of contained household sanitation were more than 3 log-units lower than those outside of clusters. Further, although results were not always statistically significant, E. coli concentrations in drains showed consistent trends with household sanitation coverage clusters: concentrations were lower in or near clusters of high coverage of household sanitation facilities-especially contained facilities-and vice versa. Virus detection in drains and E. coli concentrations in soil were not significantly associated with clustering of any type of household sanitation and did not exhibit consistent trends. Population density alone was not significantly associated with any of the fecal contamination outcomes by itself and was a significant, yet inconsistent, effect modifier of the association between sanitation clusters and E. coli concentrations. These findings suggest clustering of contained household sanitation, even when shared, may be associated with lower levels of fecal contamination within drains in the immediate public domain. Further research is needed to better quantify these relationships and examine impacts on health.
