MeetingRecommendations of joint FAO/WHO Rift Valley fever outbreaks forecasting models brainstorming workshop
29 September – 1 October 2008
2008Also available in:
No results found.Rift Valley fever (RVF) is a viral zoonosis that was first identified in Kenya in 1931. This mosquitoborne disease primarily affects animals but also has the capacity to infect humans. The majority of animal infections result from infected mosquito bites, while most human infections are caused by direct or indirect contact with the blood or organs of infected animals. Such contact may occur during the care or slaughtering of infected animals or possibly from the ingestion of raw milk. Human infection can also result from the bites of infected mosquitoes. RVF outbreaks in East Africa are closely associated with periods of heavy rainfall that occur during the warm phase of the El Niño/Southern Oscillation (ENSO) phenomenon. These findings have enabled the successful development of forecasting models and early warning systems for RVF using satellite images and weather/climate forecasting data, enabling authorities to implement measures to avert impending epidemics. -

Forecasting threats to the food chain affecting food security in countries and regions
2020Also available in:
No results found.During the period April to June 2020, Food Chain Crisis (FCC) threats are expected to occur in Africa, the Americas, Asia and Europe where they can persist within a country, spread to neighbouring countries, remain latent, or re-emerge or amplify. The dynamics and likelihood of the occurrence of FCC threats depend on a number of risk factors or drivers. These include agro-ecological factors (intensive farming systems, deforestation, overgrazing, etc.), climate change and variability (droughts, extreme weather events, flooding, heavy rains, heat waves, the El Niño-Southern Oscillation – ENSO –), changes in vegetation cover, water temperature, human behaviour (cultural practices, conflicts and civil insecurity, trade, etc.) and natural disasters. In relation to food security, and according to the last “Crop prospects and food situation” report (April to June 2020), FAO estimates that, globally, 44 countries (34 in Africa, eight in Asia, and two in Americas) are in need of external assistance for food. Persisting conflicts continue to be the dominant factor driving high levels of severe food insecurity. Weather shocks have also adversely affected food availability and access. FCC threats can compound food insecurity in fragile countries stricken by weather shocks and conflicts. Main Food Chain Threats. Thirty two plant and forest pests and diseases, locusts and animal and aquatic diseases were monitored and forecasted by FAO experts for the period April to June 2020. A total of 279 forecasts were conducted in 131 countries. -

FCC threats can compound food insecurity in fragile countries stricken by weather shocks and conflicts. Main food chain threats: Twenty-six plant and forest pests and diseases, locusts and animal and aquatic diseases were monitored and forecasted by FAO experts for the period July to September 2020. A total of 243 forecasts were conducted in 123 countries.
