Food security monitoring in Africa
» Main constraints in Africa
» Less information on Agriculture, subsistence agriculture, highly fragmented
» Vulnerable to climate events (drought, floods, ...) with potentially high human impact
» Limited capacity locally
» VITO works together with
» FAO, WFP, local ministries
» Partnership in Europe through GMFS (Global monitoring for Food Security project)
» To
» To strengthen capacity
» To assess the agricultural season (anomalies, yield, area)
