Remote sensing activities
VITO?
» Is a non-profit organization established by the Flemish Government to:
» Stimulate a positive, innovative climate to strenghten SME’s
» Put Flanders on the “European & global” map (including it’s
international commitments)
» Bridge scientific & operational communities
» Modes of operation:
» Through 5-year framework contracts with the Flemish Gov:
» At least 50% income from contract research (relevance!)
» Publish SCI papers
» Create spin-offs (+ patents)
» Energy, industrial materials, environmental modelling, remote
sensing, …
» 600+employees

EUMETCast - concept
» What is EUMETCast?
» A multi-service dissemination system based on standard Digital
Video Broadcast (DVB-S) technology, using commercial
telecommunication satellites to multicast files (data and products) to
a wide user community
» Off-the shelf, standard, low cost, commercially available reception
equipment (comparable to household satellite TV)
» Operated by EUMETSAT
» Fast (12-14Mbps in EU)
& reliable

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)
