Imaginez que tous les habitants de Glasgow, Turin ou Lyon ont \u00e9t\u00e9 contraints de fuir leurs foyers. Voil\u00e0 l'ampleur de la crise humanitaire qui s\u00e9vit dans la r\u00e9gion du Darfour au Soudan en Afrique.<\/p>\n<\/div>\n

Environ 1,5 millions de personnes ont \u00e9t\u00e9 d\u00e9plac\u00e9es de leurs villages dans une zone de la taille de la France. Le territoire \u00e0 couvrir est tellement vaste que les images satellites sont d'une importance vitale pour les humanitaires en mission sur le terrain.<\/p>\n

Un groupe soutenu par l'ESA, appel\u00e9 Respond, utilise ces images pour la production de cartes \u00e0 jour des camps diss\u00e9min\u00e9s sur ce territoire et du paysage environnant.<\/p>\n

En moins de 12 heures, ces images sont directement envoy\u00e9es aux travailleurs des organisations humanitaires, comme la Croix Rouge, les Nations Unies, l'agence f\u00e9d\u00e9rale allemande de secours aux catastrophes.<\/p>\n

L'\u00e9quipe Respond utilise 10 capteurs de 9 satellites. Ils re\u00e7oivent entre autres des donn\u00e9es d'un instrument radar et d'un syst\u00e8me de cam\u00e9ra embarqu\u00e9s sur le satellite Envisat de l'ESA.<\/p>\n

Le radar \u00e0 bord d'Envisat, qui peut voir \u00e0 travers les nuages, de jour comme de nuit, a \u00e9t\u00e9 particuli\u00e8rement pr\u00e9cieux pendant la saison des pluies au Soudan.<\/p>\n

En plus des photos satellites, comme celles de SPOT-5, le radar a permis de voir des zones inond\u00e9es et des routes encore praticables.<\/p>\n

Par ailleurs, les satellites de la constellation d'observation des catastrophes construits par les Britanniques pr\u00e9parent des cartes de la v\u00e9g\u00e9tation locale. Ces cartes sont essentielles parce que la survie de la population du Darfour d\u00e9pend aussi de la disponibilit\u00e9 de bois pour la cuisson des repas.<\/p>","protected":false},"excerpt":{"rendered":"
