J\u00e4rved on v\u00e4\u00e4rtuslikud vee- ja toiduallikad, eriti vaestes riikides. Siiski kahjustuvad need kergesti \u00fclem\u00e4\u00e4rase kasutamise, reostuse ja kliimamuutuste t\u00f5ttu. J\u00e4rvede suuruse ja kaldajoone muutusi on kosmosest h\u00e4sti n\u00e4ha.<\/p>\n<\/div>\n

Selline teave on v\u00e4ga v\u00e4\u00e4rtuslik \u00e4\u00e4repoolsetes piirkondades ja vaestes riikides. See n\u00e4itab, kuidas p\u00f5llumajandus ja ilmastik m\u00f5jutavad veetaset. Samuti hoiatab see l\u00e4heduses elavaid inimesi \u00fcleujutuste eest.<\/p>\n

Satelliidid annavad ka olulist teavet j\u00e4rvede seisundi kohta, sealhulgas vee temperatuuri, v\u00e4rvi ja reostuse kohta.<\/p>\n

\u00dcks k\u00f5ige dramaatilisemaid n\u00e4iteid on Arali meri Kasahstanis. Kunagi oli see maailma suuruselt neljas j\u00e4rv, kuid viimase 45 aasta jooksul on selle pindala kahanenud alla poole algsest suurusest.
ESA satelliidi Envisat ja teiste satelliitide pildid n\u00e4itavad, kuidas inimtegevuse tagaj\u00e4rjel on Araali merre suubuvad j\u00f5ed kahanenud vaid n\u00f5rgaks nireks. Selle tulemusena on j\u00e4rv tegelikult kaheks jagunenud. N\u00fc\u00fcd \u00fcmbritseb j\u00e4rve \u00e4\u00e4res 40 000 ruutkilomeetrit valget, soolast mulda.<\/p>\n

Kosmoses asuvad radarid suudavad m\u00f5\u00f5ta ka j\u00e4rvede ja neid toitvate j\u00f5gede muutuvat veetaset. Suuremas osas Araali merest on veetase alates 1960. aastatest langenud 14 meetrit. Siiski on j\u00e4rve p\u00f5hjaosas veetaseme t\u00f5stmiseks ja soolsuse v\u00e4hendamiseks tehtud j\u00f5upingutused viimastel aastatel m\u00f5ningast edu toonud.<\/p>","protected":false},"excerpt":{"rendered":"
