Jezera jsou cenn\u00fdm zdrojem vody a potravy, zejm\u00e9na v chud\u00fdch zem\u00edch. Jsou v\u0161ak n\u00e1chyln\u00e1 k po\u0161kozen\u00ed v d\u016fsledku nadm\u011brn\u00e9ho vyu\u017e\u00edv\u00e1n\u00ed, zne\u010di\u0161t\u011bn\u00ed a klimatick\u00fdch zm\u011bn. Zm\u011bny velikosti a pob\u0159e\u017e\u00ed jezer lze snadno pozorovat z vesm\u00edru.<\/p>\n<\/div>\n

Tyto informace jsou velmi cenn\u00e9 v odlehl\u00fdch oblastech a chud\u00fdch zem\u00edch. Ukazuj\u00ed, jak zem\u011bd\u011blstv\u00ed a po\u010das\u00ed ovliv\u0148uj\u00ed hladiny vody. Z\u00e1rove\u0148 varuj\u00ed obyvatele v okol\u00ed p\u0159ed povodn\u011bmi.<\/p>\n

Satelity tak\u00e9 poskytuj\u00ed d\u016fle\u017eit\u00e9 informace o stavu jezer, v\u010detn\u011b teploty vody, jej\u00ed barvy a zne\u010di\u0161t\u011bn\u00ed.<\/p>\n

Jedn\u00edm z nejv\u00fdrazn\u011bj\u0161\u00edch p\u0159\u00edklad\u016f je Aralsk\u00e9 jezero v Kazachst\u00e1nu. Kdysi \u010dtvrt\u00e9 nejv\u011bt\u0161\u00ed jezero na sv\u011bt\u011b se za posledn\u00edch 45 let zmen\u0161ilo na m\u00e9n\u011b ne\u017e polovinu sv\u00e9 p\u016fvodn\u00ed rozlohy.
Sn\u00edmky ze satelit\u016f, jako je nap\u0159\u00edklad Envisat agentury ESA, ukazuj\u00ed, jak lidsk\u00e1 \u010dinnost zredukovala toky \u0159ek \u00fast\u00edc\u00edch do Aralsk\u00e9ho jezera na pouh\u00e9 pram\u00ednky. V d\u016fsledku toho se jezero dokonce rozd\u011blilo na dv\u011b \u010d\u00e1sti. Kolem jeho b\u0159eh\u016f se nyn\u00ed rozprost\u00edr\u00e1 pou\u0161\u0165 o rozloze 40 000 \u010dtvere\u010dn\u00edch kilometr\u016f s b\u00edlou, slanou p\u016fdou.<\/p>\n

Radarov\u00e9 p\u0159\u00edstroje ve vesm\u00edru mohou tak\u00e9 m\u011b\u0159it zm\u011bny hladiny jezer a \u0159ek, kter\u00e9 do nich \u00fast\u00ed. Ve v\u011bt\u0161in\u011b oblasti Aralsk\u00e9ho mo\u0159e klesla hladina vody od 60. let o 14 metr\u016f. \u00dasil\u00ed o zv\u00fd\u0161en\u00ed hladiny vody a sn\u00ed\u017een\u00ed slanosti v severn\u00ed \u010d\u00e1sti jezera v\u0161ak v posledn\u00edch letech p\u0159ineslo ur\u010dit\u00e9 \u00fasp\u011bchy.<\/p>","protected":false},"excerpt":{"rendered":"
