Jeziora stanowi\u0105 cenne \u017ar\u00f3d\u0142o wody i po\u017cywienia, zw\u0142aszcza w krajach ubogich. S\u0105 one jednak podatne na zniszczenia spowodowane nadmiern\u0105 eksploatacj\u0105, zanieczyszczeniem i zmianami klimatu. Zmiany wielko\u015bci i linii brzegowej jezior mo\u017cna \u0142atwo zaobserwowa\u0107 z kosmosu.<\/p>\n<\/div>\n

Informacje te s\u0105 niezwykle cenne w odleg\u0142ych regionach i krajach ubogich. Pokazuj\u0105 one, w jaki spos\u00f3b rolnictwo i warunki pogodowe wp\u0142ywaj\u0105 na poziom wody. Stanowi\u0105 one r\u00f3wnie\u017c ostrze\u017cenie przed powodziami dla os\u00f3b mieszkaj\u0105cych w pobli\u017cu.<\/p>\n

Satelity dostarczaj\u0105 r\u00f3wnie\u017c wa\u017cnych informacji na temat stanu jezior, w tym temperatury wody, jej barwy i stopnia zanieczyszczenia.<\/p>\n

Jednym z najbardziej dramatycznych przyk\u0142ad\u00f3w jest Morze Aralskie w Kazachstanie. Niegdy\u015b czwarte co do wielko\u015bci jezioro na \u015bwiecie, w ci\u0105gu ostatnich 45 lat skurczy\u0142o si\u0119 do rozmiar\u00f3w mniejszych ni\u017c po\u0142owa pierwotnej powierzchni.
Zdj\u0119cia z satelit\u00f3w, takich jak Envisat nale\u017c\u0105cy do ESA, pokazuj\u0105, jak dzia\u0142alno\u015b\u0107 cz\u0142owieka sprawi\u0142a, \u017ce rzeki wp\u0142ywaj\u0105ce do Morza Aralskiego zamieni\u0142y si\u0119 w stru\u017cki. W rezultacie jezioro faktycznie podzieli\u0142o si\u0119 na dwie cz\u0119\u015bci. Wok\u00f3\u0142 jego brzeg\u00f3w rozci\u0105ga si\u0119 obecnie pustynia o powierzchni 40 000 kilometr\u00f3w kwadratowych, pokryta bia\u0142\u0105, s\u0142on\u0105 gleb\u0105.<\/p>\n

Urz\u0105dzenia radarowe znajduj\u0105ce si\u0119 w przestrzeni kosmicznej mog\u0105 r\u00f3wnie\u017c mierzy\u0107 zmiany poziomu w\u00f3d jezior oraz rzek, kt\u00f3re je zasilaj\u0105. W wi\u0119kszo\u015bci obszaru Morza Aralskiego poziom wody obni\u017cy\u0142 si\u0119 o 14 metr\u00f3w od lat 60. XX wieku. Jednak dzia\u0142ania maj\u0105ce na celu podniesienie poziomu wody i zmniejszenie zasolenia w p\u00f3\u0142nocnej cz\u0119\u015bci jeziora przynios\u0142y w ostatnich latach pewne sukcesy.<\/p>","protected":false},"excerpt":{"rendered":"
