The insidious impact of morbidity: billions of diarrhoeal disease and malaria episodes; hyper-endemic intestinal worm infections; chronic under- and malnutrition; chronic effect of exposure to arsenic or pesticides …
What is prevention?
What are the economic dimensions of managing determinants of health rather than managing disease?
Do emerging diseases take prevalence over long-time health crises to which we have become accustomed?

Managing hazards and risks along agricultural value chainsManaging hazards and risks along agricultural value chains
• Establish health-based targets for your outcome for vulnerable groups
• Identify hazards and assess risks at each critical point along the chain
• Design safeguards and risk mitigation measures along your chain that add up to achieve your health-based target

Wastewater use in agriculture: Wastewater use in agriculture: Situation and trendsSituation and trends
• Fresh water resources are rapidly becoming scarce. • Rapid urbanization is resulting in increasing outflows of domestic wastewater.• There is a growing market of urban workers looking for fast food with “green”
ingredients • Fertilizers are a costly input into the agricultural production system.
Result: Farmers in rural and peri-urban areas are turning to the use of wastewater, excreta and greywater in agriculture and aquaculture in increasing numbers.
Without effective risk assessment and management, such use incurs important health hazards. The associated water-borne disease risks affect farmers and their families, those who market the produce and consumers.

• Ten percent of the world’s population is thought to consume wastewater irrigated foods.
• Twenty million hectares in 50 countries are irrigated with raw or partially treated wastewater.
• The use of excreta (faeces, urine) is important worldwide, but the extent has not been quantified.
• The use of greywater is growing in both developed and less-developed countries – it is culturally more acceptable in some societies.
