St\u00f8rstedelen af verdens befolkning bor i n\u00e6rheden af floder. De er afh\u00e6ngige af floderne til drikkevand, vask, fiskeri og vanding af afgr\u00f8der.<\/p>\n<\/div>\n

I fjerntliggende skove eller \u00f8rkener kan floder v\u00e6re den nemmeste m\u00e5de at rejse p\u00e5. Der kan opf\u00f8res d\u00e6mninger for at forhindre oversv\u00f8mmelser, for at vande n\u00e6rliggende marker eller for at producere elektricitet.<\/p>\n

Hvis floderne ikke holdes under kontrol, kan t\u00f8rke eller oversv\u00f8mmelser f\u00f8re til katastrofer. Hvert \u00e5r lider millioner af mennesker under vandmangel eller oversv\u00f8mmelser af deres hjem og marker.<\/p>\n

Selv i Europa udg\u00f8r oversv\u00f8mmelser fra store floder en trussel mod menneskeliv og for\u00e5rsager enorme skader p\u00e5 byer og landbrugsjord. I 2002 for\u00e5rsagede de v\u00e6rste oversv\u00f8mmelser i Europa i mange \u00e5r skader for mere end 7 milliarder euro.<\/p>\n

Meteosat-vejrsatellitter giver tidlig varsling om kraftige regnbyger, s\u00e5 der kan tr\u00e6ffes foranstaltninger til beskyttelse mod oversv\u00f8mmelser. ESA\u2019s rumfart\u00f8jer Envisat og ERS-2 hj\u00e6lper redningstjenesterne ved at tage billeder af oversv\u00f8mmede omr\u00e5der, b\u00e5de dag og nat.<\/p>\n

Satellitter viser ogs\u00e5, hvor det er bedst at grave br\u00f8nde, hvor meget vand der er i jorden, og om vandstanden i floderne stiger eller falder. Dette er meget v\u00e6rdifuldt i fattige lande, hvor s\u00e5danne oplysninger er sv\u00e6re at f\u00e5 fat i.<\/p>\n

Siden 2002 har ESA\u2019s TIGER-program hjulpet mange afrikanske lande med at overv\u00e5ge deres floder og v\u00e5domr\u00e5der og udnytte deres vandressourcer bedst muligt.<\/p>","protected":false},"excerpt":{"rendered":"
