Risk assessments related to use of water and safety of fresh produce originate from both water and food microbiology studies. Although the set-up and methodology of risk assessment in these 2 disciplines may differ, analysis of the current literature reveals some common outcomes. Most of these studies from the water perspective focus on enteric virus risks, largely because of their anticipated high concentrations in untreated wastewater and their resistance to common wastewater treatments. Risk assessment studies from the food perspective, instead, focus mainly on bacterial pathogens such as Salmonella and pathogenic Escherichia coli. Few site-specific data points were available for most of these microbial risk assessments, meaning that many assumptions were necessary, which are repeated in many studies. Specific parameters lacking hard data included rates of pathogen transfer from irrigation water to crops, pathogen penetration, and survival in or on food crops. Data on these factors have been investigated over the last decade and this should improve the reliability of future microbial risk estimates. However, the sheer number of different foodstuffs and pathogens, combined with water sources and irrigation practices, means that developing risk models that can span the breadth of fresh produce safety will be a considerable challenge. The new approach using microbial risk assessment is objective and evidence-based and leads to more flexibility and enables more tailored risk management practices and guidelines. Drawbacks are, however, capacity and knowledge to perform the microbial risk assessment and the need for data and preferably data of the specific region.

Contamination of shallow tube well drinking water by naturally occurring arsenic is a severe societal and human health challenge in Bangladesh. Multiple technological interventions seeking to ameliorate the problem face hurdles in securing social acceptance, i.e. the willingness of users to receive and use a technology. While most papers focus on expert understanding of social acceptability, this paper analyzes how users themselves understand the factors shaping the social acceptability of safe drinking water options in rural Bangladesh. We then deploy such understanding to comparatively assess which factors users see as most important in securing social acceptance for three safe drinking water options in rural Bangladesh: the arsenic removal household (Sono) filter; the deep tube well; and an improved dug well. We draw on focus groups and semi-structured interviews with technology users in six villages across three districts to analyze how users assess the social acceptability of specific arsenic-safe technologies. Our findings highlight that factors such as availability, affordability and compatibility with existing water use practices, as understood by users, are key to securing users’ acceptance of a specific arsenic-safe option. In concluding, we point to a future research agenda to analyze user-oriented social acceptability of arsenic-safe technologies in developing country contexts.

Locally managed handpumps provide water services to around 200 million people in rural Africa. Handpump failures often result in extended service disruption leading to high but avoidable financial, health, and development costs. Using unique observational data from monitoring handpump usage in rural Kenya, we evaluate how dramatic improvements in maintenance services influence payment preferences across institutional, operational, and geographic factors. Public goods theory is applied to examine new institutional forms of handpump management. Results reveal steps to enhance rural water supply sustainability by pooling maintenance and financial risks at scale supported by advances in monitoring and payment technologies.

Community-based financing of rural water supply operation and maintenance is a well-established policy principle in sub-Saharan Africa. Yet evidence from over 90,000 waterpoints in five sub-Saharan African countries suggests a majority of communities fail to establish and sustain a revenue collection system. As a result, insufficient finances to repair waterpoints can lead to lengthy downtimes or abandonment, threatening the health and welfare of millions of water users forced to revert to unsafe or distant alternatives. Applying a social-ecological systems framework to community waterpoints in rural Kenya, we empirically assess the prevalence and determinants of financial contributions among water users. The analysis draws on multi-decadal data covering 229 years' worth of water committee financial records consisting of more than 53,000 household payments. Results reveal that non-payment and late payment are prevalent, and payment behaviours are predicted by groundwater quality, waterpoint location, productive water use, and rainfall season. The findings reflect the socio-ecological nature of waterpoint sustainability in rural sub-Saharan Africa and confirm that households are not always willing and able to pay for an improved water supply. This situation is symptomatic of a fundamental operation and maintenance financing challenge that must be addressed if the Sustainable Development Goal of universal access to safe water is to be achieved.

Within South East Asia, certification and local market development may play an important role in incentivizing farmers to continue with nature-based solutions delivered by organic or traditional farming practices and avoid using environmentally detrimental production techniques. The purpose of this study is to use economic valuation in order to achieve an empirical understanding of local consumer preferences for different attributes of rice products. Application of the agrarian system approach reveals that rice cultivation systems observed in the Tonle Sape Lake of the Mekong River Basin in Cambodia (our study case) may target three ecosystem services that present the characteristics of public goods and may benefit consumer support. A choice experiment survey was administered among local consumers in the city of Phnom Penh in 2013. Econometric analysis indicates high rate of non-attendance for the price attribute. It also suggests that 17% of the respondents made their choices neglecting attributes describing ecosystem services. However, there are evidence of consumers' willingness to pay (WTP) for certified organic rice higher than the price-premium observed on the local market. Furthermore, there is additional WTP value for the preservation of ecosystem services. We discuss the implications of our findings on potential payment for ecosystem services in the specific case of rice.

Recycling of wastewater provides a substantial solution to the global issue of water scarcity and high water use in aquaculture. However, this sustainable way of wastewater use has not been given much attention and exploration. This study focused on the consumer preference for fish grown in treated wastewater as well as the effect of aeration on the growth performance and economic benefit of African catfish (Clarias gariepinus) grown in treated wastewater. Two hundred (200) respondents from two communities (Chirapatre and Gyinyase) near the wastewater treatment plant in Kumasi were interviewed to determine their willingness to accept and pay for African catfish grown in treated wastewater. For the growth trial, a total of 600 fish (of average initial weight 39.12g) were stocked in two maturation ponds with 4 h (3:00am–7:00am) of aeration daily. The trial lasted for 12 weeks and variables monitored included the survival, growth performance (weight gain, specific growth rate, and yield) and water quality. Fish cultured in non-aerated wastewater ponds (NWFPs) under similar conditions as in aerated wastewater-fed ponds (AWFPs) served as control. The results indicated most important considerations for consumers in their choice of fish to consume were in order of importance; food safety, freshness of fish, taste and packaging. The proximity of consumers to the treatment plant, the price of fish, religion, and age and whether or not they were fish consumers affected their willingness to pay for African catfish grown in the treated wastewater significantly. For the growth trial, dissolved oxygen concentrations in the aerated ponds were significantly higher than in the NWFPs and this led to more than a doubling of the growth rates in the African catfish grown in the AWFPs (189.10g 11.32) as compared to the NWFPs (90.70g 11.59). The pond aeration improved fish growth significantly (p < 0.0098). On economic benefit, the aerated system yielded profits of 618.83 (€103.13) as compared to a loss of 104.99 (€17.50), which was incurred in the non-aerated ponds. Education of the consumers on the process of wastewater treatment and establishment of food safety guidelines will therefore be recommended to increase consumer interest in consuming fish from the treated wastewater.

Tunisia, like most countries in the Middle East and North Africa (MENA) region, has limited renewable water resources and is classified as a water stress country. The effects of climate change are exacerbating the situation. The agricultural sector is the main consumer (80%) of blue water reserves. In this study, to better understand the factors that influence the food water footprint of Tunisian consumers, we used a multiple linear regression model (MLR) to analyze data from 4853 households. The innovation in this paper consists of integrating effects of socio-economic, demographic, and geographic trends on the food consumption water footprint into the assessment of water and food security. The model results showed that regional variations in food choices meant large differences in water footprints, as hypothesized. Residents of big cities are more likely to have a large water footprint. Significant variability in water footprints, due to different food consumption patterns and socio-demographic characteristics, was also noted. Food waste is also one of the determining factors of households with a high water footprint. This study provides a new perspective on the water footprint of food consumption using “household” level data. These dietary water footprint estimates can be used to assess potential water demand scenarios as food consumption patterns change. Analysis at the geographic and socio-demographic levels helps to inform policy makers by identifying realistic dietary changes.

Despite its significant adverse impacts on the environment, society, and economy, food waste is unavoidable around the world. The increase in population and income will worsen the situation and put more pressure on food security. This paper explores the problem and the factors that are influencing food waste in Malaysia. It also discusses a proposed alternative treatment of food waste and an analysis of its marketability. Accordingly, an experimental analysis and a questionnaire survey are used to achieve the stated objectives. The result shows that on average, the amount of food waste per capita/week is about 1.6 kg, with rice as the most commonly wasted food. Poor food management practices and gender are significant factors that affect food waste, and these are supported by the consumer behaviours theory. The proposed treated rice waste (termed as upcycled products) using a circular economy model was produced and well accepted by the public; the people's willingness to pay a certain amount of money to process their food waste indicates a high chance of food waste marketability.
