Early Warning Systems on Food and Agriculture

Presentation by Stéphane Jost, Master in Human Development & Food Security Università Roma 3 - 18 May 2017

slide-2

SLIDE 2

Early Warning Systems on Food and Agriculture

Early Warning Systems activities: Three main steps

1) Data collection 2) Data analysis 3) Dissemination of information

slide-3

SLIDE 3

Early Warning Systems on Food and Agriculture : Data collection Cropped areas cropping conditions Consumption Meteorological conditions Trade, markets Prices Governmental agricultural policies Transports and storage Pests, diseases

slide-4

SLIDE 4

Early Warning Systems on Food and Agriculture : Data collection

Main sources of information come from

national services (agrométéorology, hydrology, plant protection, statistics, ...).

slide-5

SLIDE 5

Early Warning Systems on Food and Agriculture : Data collection

Crop and Food Supply Assessment Missions can also be organised

slide-6

SLIDE 6

Early Warning Systems on Food and Agriculture : Data collection

Crop Production and Food Supply Assessment (FAO) Vulnerability and Food Needs Assessment (WFP/FAO) Macroeconomic Context Affecting Food Supply, Demand (FAO)

Three main components of FAO/WFP Crop and Food Supply Assessment Missions

Early Warning Systems on Food and Agriculture : Data analysis

Cereal production in Burkina Faso

a) WinDisp

CCD dekadal image Crop zones for Sorghum Maps of roads, railways, cities,… For example :

WinDisp is a map and image display module used for the analysis and integration of satellite images, digital map and associated tabular data.
