St\u00f6rsta delen av v\u00e4rldens befolkning bor n\u00e4ra floder. De \u00e4r beroende av floderna f\u00f6r att f\u00e5 dricksvatten, tv\u00e4tta sig, fiska och vattna sina gr\u00f6dor.<\/p>\n<\/div>\n

I avl\u00e4gsna skogar eller \u00f6knar kan floder vara det enklaste s\u00e4ttet att ta sig fram. Dammar kan byggas f\u00f6r att f\u00f6rhindra \u00f6versv\u00e4mningar, bevattna n\u00e4rliggande \u00e5krar eller producera el.<\/p>\n

Om floderna inte h\u00e5lls under kontroll kan torka eller \u00f6versv\u00e4mningar leda till katastrofer. Varje \u00e5r drabbas miljontals m\u00e4nniskor av vattenbrist eller \u00f6versv\u00e4mningar som \u00f6del\u00e4gger deras hem och \u00e5krar.<\/p>\n

\u00c4ven i Europa hotar \u00f6versv\u00e4mningar i stora floder m\u00e4nniskors liv och orsakar enorma skador p\u00e5 st\u00e4der och jordbruksmark. \u00c5r 2002 orsakade de v\u00e4rsta \u00f6versv\u00e4mningarna i Europa p\u00e5 m\u00e5nga \u00e5r skador f\u00f6r mer \u00e4n 7 miljarder euro.<\/p>\n

Meteosat-v\u00e4dersatelliterna ger tidiga varningar om kraftiga regnv\u00e4der s\u00e5 att \u00f6versv\u00e4mningsskydd kan f\u00f6rberedas. ESA:s rymdfarkoster Envisat och ERS-2 hj\u00e4lper r\u00e4ddningstj\u00e4nsten genom att ta bilder av \u00f6versv\u00e4mmade omr\u00e5den, b\u00e5de dag och natt.<\/p>\n

Satellitbilder visar ocks\u00e5 var det \u00e4r b\u00e4st att gr\u00e4va brunnar, hur mycket vatten som finns i marken och om flodernas vattenniv\u00e5 stiger eller sjunker. Detta \u00e4r mycket v\u00e4rdefullt i fattiga l\u00e4nder d\u00e4r s\u00e5dan information \u00e4r sv\u00e5r att f\u00e5 tag p\u00e5.<\/p>\n

Sedan 2002 har ESA:s TIGER-program hj\u00e4lpt m\u00e5nga afrikanska l\u00e4nder att \u00f6vervaka sina floder och v\u00e5tmarker och utnyttja sina vattenresurser p\u00e5 b\u00e4sta s\u00e4tt.<\/p>","protected":false},"excerpt":{"rendered":"
