Paljud meist peavad puhast vett enesestm\u00f5istetavaks, kuid tegemist on v\u00e4\u00e4rtusliku ressursiga, millest v\u00f5ib m\u00f5nikord puudus olla. Me vajame vett joomiseks, h\u00fcgieeni tagamiseks, p\u00f5llukultuuride kasvatamiseks, loomade pidamiseks ning enda ja keskkonna tervise hoidmiseks. Kahjuks kasutatakse m\u00f5ningaid veevarusid liiga kiiresti \u00e4ra, samas kui teisi reostatakse. ESA on otsustanud kasutada oma satelliittehnoloogiat ja projekti nimega TIGER, et aidata!<\/p>\n<\/div>\n

\u00dcks suurimaid v\u00e4ljakutseid, millega inimesed silmitsi seisavad, on vajadus magevee (mitte ookeanide soolase vee) j\u00e4rele p\u00f5llumajanduses. Tegelikult kulub 70% meie kasutatavast mageveest toidu kasvatamiseks. Kuna inimeste arv Maal kasvab, on toita \u00fcha rohkem inimesi, mist\u00f5ttu on v\u00e4ga oluline, et me selle probleemiga tegeleksime. Kui me seda ei tee, j\u00e4\u00e4vad inimesed n\u00e4lga. See on eriti suur probleem Aafrika riikides, kus valitsevad k\u00f5rged temperatuurid, kliimamuutused ja kiiresti kasvav rahvastik.<\/p>\n<\/p>\n

Vaata, kuidas muutus veetase Theewaterskloofi tammis aasta jooksul. Autori\u00f5igus: sisaldab muudetud Copernicus Sentinel andmeid (2017\u201318), mida on t\u00f6\u00f6tlenud ESA, CC BY-SA 3.0 IGO.<\/p>\n

Maad \u00fcmbritsevad ESA satelliidid suudavad vaadata alla meie planeedile ja j\u00e4lgida veevarusid, saastetasemeid, \u00fcleujutusi, aurustumist ja isegi mulla niiskust. ESA TIGER-projekt teeb koost\u00f6\u00f6d Aafrika partnerite ja teiste partneritega \u00fcle kogu maailma, et edastada seda olulist teavet veekasutuse \u00fcle otsuseid tegevatele inimestele.<\/p>\n

N\u00e4iteks on L\u00f5una-Aafrika Vabariigi L\u00e4\u00e4ne-Kapimaa provintsis valitsenud veepuudus. Theewaterskloofi tamm on piirkonna, sealhulgas Kaplinna elanike, p\u00f5llumajandusettev\u00f5tete ja loomade jaoks suurim veeallikas. Veepuuduse t\u00f5ttu on p\u00f5llumajandustootjad kasvanud 36% v\u00e4hem teravilja kui tavaliselt, mis t\u00e4hendab, et inimestel on v\u00e4hem toitu. N\u00fc\u00fcd j\u00e4lgivad ESA satelliidid TIGER-projekti raames olukorda ja aitavad inimestel veevarustust hoolikalt hallata, kasutades olemasolevat vett v\u00f5imalikult t\u00f5husalt.<\/p>\n<\/p>\n

Vaadake, kuidas ESA satelliidid aitavad v\u00e4\u00e4rtuslikke veevarusid hallata. Autori\u00f5igus: EO4SD-Water konsortsium.<\/p>\n

Kas sul on alati v\u00e4rsket ja puhast vett, kui seda vajad? Kui jah, siis kuidas sinu arvates oleks elu, kui seda poleks?<\/p>\n

Huvitav fakt:<\/b> TIGER kasutab ESA k\u00f5rgtehnoloogilisi satelliite Sentinel-1 ja Sentinel-2 Aafrika riikide veetaseme j\u00e4lgimiseks.<\/p>","protected":false},"excerpt":{"rendered":"
