\u00dchel USA p\u00f5llumajandustootjate r\u00fchmal on probleem: juba aastaid on nad kasutanud suuri veekoguseid p\u00f5llukultuuride kasvatamiseks hiiglaslikel p\u00f5ldudel, kuid n\u00fc\u00fcd on nende veevarud otsa saamas. Abi v\u00f5ib tulla ESA spin-off-tehnoloogiast, mis aitaks veevarusid s\u00e4\u00e4sta, tagades samal ajal, et p\u00f5llukultuurid ei j\u00e4\u00e4ks janusse!<\/p>\n<\/div>\n

Kava autor on endine ESA t\u00f6\u00f6taja Javier Marti. Ta m\u00e4rkas, et m\u00f5ningaid p\u00f5lde kastetakse liiga palju, mis on v\u00e4ga raiskav. Kas oleks v\u00f5imalik satelliitide abil kindlaks teha, millised p\u00f5llud t\u00f5epoolest vett vajavad? Javier arvab, et on!<\/p>\n

V\u00f5tmet\u00e4htsusega on Maa \u00fcmber tiirlevad satelliidid, mida tavaliselt kasutatakse inimeste abistamiseks navigeerimiss\u00fcsteemide abil teed leidmisel. Anal\u00fc\u00fcsides peegeldunud satelliitnavigatsioonisignaale avastas Javier, et on v\u00f5imalik m\u00f5\u00f5ta, kui palju vett on allpool asuval pinnasel: mullas, lumes, m\u00e4rgaladel ja isegi veehoidlate veetaset. Need signaalid v\u00f5imaldavad kindlaks teha, millised p\u00f5llud vajavad niisutamist ja millised on niisugused, nagu nad on.<\/p>\n

J\u00e4rgmise paari kuu jooksul hakkavad mitmed p\u00f5llumajandustootjad neid andmeid kasutama, et reguleerida oma p\u00f5ldude kastmist. Loodetakse, et see t\u00f5husam meetod aitab neil s\u00e4\u00e4sta 30% tavap\u00e4rasest veekulust. Lisaboonusena v\u00f5ivad p\u00f5llukultuurid kasvada isegi paremini, kuna saavad just \u00f5ige koguse vett!<\/p>\n

Kui Javieri idee toimib, v\u00f5iks seda kasutada kogu maailmas vee s\u00e4\u00e4stmiseks \u2013 ja seda t\u00e4nu satelliitidele, mis juba tiirlevad Maa orbiidil.<\/p>\n
