Indawo: eMelbourne, eOstreliya — Kwinkqubela phambili ebalulekileyo kwezolimo oluchanekileyo, abalimi baseOstreliya baya besebenzisa iindlela zokulinganisa imvula zeradar ukuphucula amaqhinga abo okulawula amanzi nokuphucula isivuno sezityalo phakathi kweemeko zemozulu ezitshintshayo.
Ngokwesiko, iigeyiji zemvula beziyeyona ndlela isetyenziswa kakhulu yokulinganisa imvula, kodwa uphuculo lwakutshanje kwitekhnoloji yeradar luvumela idatha yemvula echanekileyo nefike ngexesha. Iigeyiji zemvula ezintsha zeradar zisebenzisa iinkqubo zeradar zeDoppler ukufumanisa ukufuma kunye neepateni zemvula kwindawo ebanzi. Le teknoloji inokubonelela ngedatha yexesha langempela malunga nobungakanani bemvula kunye nokusasazwa kwayo, ivumela abalimi ukuba benze izigqibo ezinolwazi malunga nokunkcenkceshela, ukuchumisa, kunye nolawulo lwezinambuzane.
“Ngenxa yokuguquguquka kwemozulu kunye neendlela zemozulu eziguquguqukayo ngakumbi, ukukwazi ukufikelela kwidatha echanekileyo yemvula ngexesha langempela kubalulekile kwizolimo ezizinzileyo,” utshilo uGqr. Lisa Wang, ingcali yemozulu kunye nengcali yezobuchwepheshe bezolimo kwiYunivesithi yaseQueensland. “Iigeyiji zemvula yeradar zibonelela ngengqiqo epheleleyo enceda abalimi ukuba baphucule ukusetyenziswa kwamanzi, banciphise inkunkuma, kwaye baphucule impilo yezityalo.”
Ukuchaneka kwedatha okuphuculweyo kunye nokuqonda okucwangcisiweyo
Enye yeenzuzo ezibalulekileyo zeeradar rain gauges kuneendlela zemveli kukuba ziyakwazi ukunika ulwazi olucacileyo. Iirain gauges eziqhelekileyo zikhawulelwe kwiimilinganiselo zamanqaku kwaye zinokuphoswa lula ziinguqu ezibalulekileyo kumgama omncinci. Ngokwahlukileyo koko, iteknoloji yeradar inokubamba idatha yemvula kwiindawo ezinkulu kwaye ivelise iimaphu ezineenkcukacha zemvula, okuvumela abalimi ukuba bahlole ukuba ingakanani imvula enayo phi kwaye nini.
Umzekelo, abalimi baseMurray-Darling Basin, enye yezona ndawo zibalulekileyo kwezolimo e-Australia, baxele ngophuculo olukhulu kwimisebenzi yabo yokulawula amanzi ukususela oko badibanisa iigeyiji zemvula yeradar kwimisebenzi yabo. Besebenzisa obu buchwephesha, abalimi banokulungisa iishedyuli zokunkcenkceshela ngokusekelwe kulwazi lwamva nje lwemvula, nto leyo ekhokelela kwizicwangciso ezingcono zokonga amanzi kunye nokusebenza kakuhle kokusetyenziswa kwamanzi.
Isifundo Setyala: Ulawulo Lwezichumiso kunye Nesivuno Sezityalo
Ukusetyenziswa kweeradar radar rain gauges kukwabonakalise ukuba luncedo ekulawuleni ukusetyenziswa kwezichumiso. Abalimi ngoku bayakwazi ukujonga ixesha lokusetyenziswa kwezichumiso zabo ngokuchanekileyo ngokusekelwe kuqikelelo lwemvula, ukuqinisekisa ukuba izondlo zifunxwa ngempumelelo zizityalo endaweni yokukhukuliswa. Oku kuchanekileyo akupheleli nje ekukhuliseni isivuno sezityalo kodwa kunciphisa nempembelelo yokusingqongileyo yokukhukuliswa kwezichumiso kwiindlela zamanzi ezikufutshane.
UJohn Carter, umlimi werayisi waseNew South Wales, wabelane ngamava akhe: “Ukususela oko saqala ukusebenzisa ii-radar rain gauges, sibone umahluko obonakalayo kwisivuno sethu serayisi. Siyakwazi ukufaka izichumisi ngaphambi kokuba kubekho imvula, oko kuthetha ukuba izityalo zethu zifumana izondlo ezizidingayo xa zifuna. Yinto etshintsha indlela esilawula ngayo igalelo lethu.”
Imingeni kunye namathemba exesha elizayo
Nangona iingenelo zeeradar rain gauges ziqatshelwa ngokubanzi, kukho imingeni yokwamkelwa ngokubanzi, kuquka iindleko zezixhobo ezisetyenziswa kwangaphambili kunye nesidingo sokuba abalimi baziqhelanise netekhnoloji. Nangona kunjalo, iingcali zoshishino zilindele ukuba njengoko itekhnoloji ifikeleleka kwaye ifikeleleka lula, ukuhlanganiswa kwayo kulo lonke ezolimo zase-Australia kuya kuqhubeka nokukhula.
Urhulumente wase-Australia ukwaxhasa olu tshintsho, etyala imali kwiinkqubo zophando lwezolimo kunye nophuhliso ezikhuthaza ubuchwepheshe banamhlanje ukuphucula ukuqina kwezolimo kutshintsho lwemozulu. Ezi zicwangciso zijolise ekuqinisekiseni ukuba abalimi banokusebenzisa ubuchwepheshe bamva nje ukugcina imveliso ngelixa begcina izixhobo.
“Njengoko sijongene nemingeni ebangelwa kukutshintsha kwemozulu, kubalulekile ukuba sityale imali kwitekhnoloji exhasa ezolimo ezizinzileyo,” utshilo uMphathiswa wezoLimo, uSenator Murray Watt. “Iiradar rain gauges zimele icandelo eliphambili lephazili, zibonelela abalimi ngedatha abayidingayo ukuze benze izigqibo ezinolwazi kwaye bazivumelanise neemeko ezitshintshayo.”
Isiphelo
Ukuhlanganiswa kweeradar rain gauges kwezolimo zase-Australia kubonisa inyathelo elibalulekileyo eliya kwiindlela zolimo ezizinzileyo nezisebenzayo. Njengoko abalimi abaninzi beqala ukusebenzisa obu buchwepheshe butsha, bunamandla okuguqula ulawulo lwamanzi, buphucule isivuno sezityalo, kwaye buphucule ukuqina kwecandelo lezolimo kwimeko yemozulu engaqhelekanga. Ngophuhliso oluqhubekayo kunye nenkxaso evela kurhulumente nakuluntu lwezolimo, ikamva lokulima e-Australia libonakala liqhutywa yidatha kwaye lisebenza kakuhle kunangaphambili.
