To identify interventions which reduce health risks of consumers where highly polluted irrigation water is used to irrigate vegetables in West Africa, scientists worked over 5 years with farmers, market traders and street food vendors in Ghana. The most promising low-cost interventions with high adoption potential were analyzed for their ability to reduce common levels of pathogens (counts of fecal coliforms and helminth eggs). The analysis showed the combination potential of various interventions, especially on-farm and during vegetable washing in line with the World Health Organization (WHO) guidelines. The tested market-based interventions were important to prevent new or additional contamination.

With increasing change of traditional diets, and the emergence of new supply and marketing chains, urban food consumers in low-income countries are faced with multiple food safety challenges, among which microbial contamination and pesticides are key concerns for fruits and vegetables sold on urban markets in West Africa. Although consumers have a genuine interest in healthy food, and are willing to pay premiums, their interpretation of food quality and risks deviates from scientific health risk assessments and does not translate into recommended risk mitigation behavior. To safeguard public health, alternative measures are needed to support consumers’ risk awareness and decision making. The review looked at common and less-common options to trigger and support behavioral change, including safety labeling (certification), corporate social responsibility models, incentive systems and social marketing of safe practices, to address potential food safety risks from farming in urban and peri-urban areas. Overall, it appears that regulatory measures for risk management, including certifications, will be – for now – less effective in the West African setup due to low educational levels in view of chemical and microbial risk, diverse and often informal food chains, poor safety supporting infrastructure and weak institutional capacities for compliance monitoring.

By affecting evapotranspiration and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e., both attenuating floods and maintaining flow during dry periods), these services are rarely factored into the planning and management of water resources. One reason for the failure to include them is lack of understanding. Very often the extent to which natural regulating functions really occur is unclear. Against this background, this report describes a simple, pragmatic approach for quantifying the flow regulating functions of natural ecosystems. The method has been applied at 14 locations in the Zambezi River Basin.

This study assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows. Results show that the annual average precipitation, actual evapotranspiration (ET) and net water yields of the whole basin were 1,192 mm, 416 mm and 615 mm, respectively. Precipitation, ET and water yields were found to be higher in the forested and mountainous upper areas of the UGB. On an annual average, present-day flows throughout UGB are about 2-8% lower than under naturalized conditions. Dry and wet season flows under climate change (CC) scenario A2 are lower than that under present climate conditions at upstream locations, but higher at downstream locations of UGB. Flows under CC scenario B2 are systematically higher and lower than that under CC scenario A2 during dry and wet seasons, respectively.

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members and 38 Partners to publish The United Nations World Water Development Report, (WWDR) series. The annual World Water Development Reports focus on strategic water issues. UN-Water Members and Partners, all experts in their respective fields, contribute the latest findings on a specific theme. The 2017 edition of the World Water Development Report focuses on 'Wastewater' and seeks to inform decision-makers, inside and outside the water community, about the importance of managing wastewater as an undervalued and sustainable source of water, energy, nutrients and other recoverable by-products, rather than something to be disposed of or a nuisance to be ignored. The report's title - Wastewater: The Untapped Resource - reflects the critical role that wastewater is poised to play in the context of a circular economy, whereby economic development is balanced with the protection of natural resources and environmental sustainability, and where a cleaner and more sustainable economy has a positive effect on the water quality. Improved wastewater management is not only critical to achieving the Sustainable Development Goal on clean water and sanitation (SDG 6), but also to other goals of the 2030 Agenda for Sustainable Development.

"Sanitation Safety Planning (SSP) is a step-by-step risk based approach to assist in the implementation of the 2006 WHO Guidelines for Safe Use of Wastewater, Excreta and Greywater in Agriculture and Aquaculture. The approach can be applied to all sanitary systems to ensure the system is managed to meet health objectives. SSP assists users to: systematically identify and manage health risk along the sanitation chain; guide investment based on actual risks, to promote health benefits and minimize adverse health impacts; provide assurance to authorities and the public on the safety of sanitation-related products and services. The SSP manual is targeted at a variety of users at different levels including; health authorities and regulators, local authorities, wastewater utility managers, sanitation enterprises and farmers, community based organizations, farmers associations and NGOs. SSP brings together actors from different sectors to identify health risks in the sanitation system and agree on improvements and regular monitoring and underscores the leadership role of the health sector."--Publisher's description.

Consumption of fruits and vegetables is important for maintaining good health and preventing chronic disease; Kenyans consume too little of these foods relative to dietary recommendations. Contaminated fruits and vegetables are an important conduit of foodborne disease (FBD), which represents a significant share of the global burden of disease, particularly in Africa. Improving the safety of fruits and vegetables and increasing their consumption are both important for improving population health. Concern about food safety is high among consumers who shop at supermarkets and specialty grocery stores in Nairobi, and prices for fruits and vegetables in these outlets far above those observed in open-air markets. This suggests significant potential for farmers to benefit economically from the production of safe, high-quality produce if credible certification systems can be developed. The FBD burden, as well as premium market opportunities for horticultural producers, are set to continue to increase in Kenya as a burgeoning middle class demands a more diversified and nutritious diet. Risk of FBD can be reduced at every stage, from farm to fork. Increasing awareness among farmers, processors, retailers, and consumers is thus a critical step toward safer food in Kenya The Kenyan government has laid out a comprehensive set of actions to improve food safety in the 2013 National Food Safety Policy, but these have yet to be implemented. Many of these interventions could be taken up by county governments. Success by KEPHIS in the enforcement of regulations in crops destined for export demonstrate the potential for public action to improve food safety in Kenya, and should be emulated in the domestic market.
