Lacurile reprezint\u0103 surse valoroase de ap\u0103 \u0219i hran\u0103, \u00een special \u00een \u021b\u0103rile s\u0103race. Cu toate acestea, ele sunt u\u0219or afectate de exploatarea excesiv\u0103, poluare \u0219i schimb\u0103rile climatice. Modific\u0103rile dimensiunilor \u0219i ale \u021b\u0103rmurilor lacurilor pot fi observate cu u\u0219urin\u021b\u0103 din spa\u021biu.<\/p>\n<\/div>\n

Aceste informa\u021bii sunt extrem de valoroase \u00een regiunile izolate \u0219i \u00een \u021b\u0103rile s\u0103race. Ele arat\u0103 cum sunt influen\u021bate nivelurile apei de activit\u0103\u021bile agricole \u0219i de condi\u021biile meteorologice. De asemenea, ele avertizeaz\u0103 popula\u021bia din zonele \u00eenvecinate cu privire la riscul de inunda\u021bii.<\/p>\n

Sateli\u021bii furnizeaz\u0103, de asemenea, informa\u021bii importante despre starea lacurilor, inclusiv temperatura apei, culoarea acesteia \u0219i gradul de poluare.<\/p>\n

Unul dintre cele mai frapante exemple este Marea Aral din Kazahstan. Odat\u0103 cel de-al patrulea lac ca m\u0103rime din lume, acesta s-a mic\u0219orat la mai pu\u021bin de jum\u0103tate din dimensiunea ini\u021bial\u0103 \u00een ultimii 45 de ani.
Imaginile captate de sateli\u021bi precum Envisat al ESA arat\u0103 cum activitatea uman\u0103 a redus la un firicel de ap\u0103 debitul r\u00e2urilor care se vars\u0103 \u00een Marea Aral. Drept urmare, lacul s-a \u00eemp\u0103r\u021bit efectiv \u00een dou\u0103. \u00cen prezent, \u00een jurul marginii sale s-a format un de\u0219ert de 40.000 de kilometri p\u0103tra\u021bi, acoperit de sol alb \u0219i s\u0103rat.<\/p>\n

Instrumentele radar din spa\u021biu pot m\u0103sura, de asemenea, varia\u021biile nivelului lacurilor \u0219i al r\u00e2urilor care le alimenteaz\u0103. \u00cen cea mai mare parte a M\u0103rii Aral, nivelul apei a sc\u0103zut cu 14 metri \u00eencep\u00e2nd cu anii 1960. Cu toate acestea, eforturile de a ridica nivelul apei \u0219i de a reduce salinitatea \u00een partea de nord a lacului au \u00eenregistrat un anumit succes \u00een ultimii ani.<\/p>","protected":false},"excerpt":{"rendered":"
