Kwindawo yezolimo ebanzi neyahlukeneyo yase-Australia, apho imbalela kunye nezikhukula zinokulawula impumelelo yezityalo kunye nendlela yokuphila, izixhobo zokulinganisa imvula zibonakala zizixhobo ezibalulekileyo kubalimi. Njengoko utshintsho lwemozulu luqhubeka luchaphazela iipatheni zemozulu, ezi zixhobo zilula kodwa ezisebenzayo ziya zisiba zibaluleke ngakumbi ekwenzeni izigqibo ezinolwazi kwezolimo.
Ukubaluleka Kokulinganisa Imvula Ngendlela Echanekileyo
Iigeyiji zemvula zisetyenziswa kulo lonke ilizwe ukubonelela ngemilinganiselo echanekileyo yemvula. Olu lwazi lubalulekileyo lunika abalimi amandla okuphucula iindlela zokunkcenkceshela, ukuhlela ukutyala nokuvuna, kwaye ekugqibeleni kuphucule isivuno sezityalo. Ngokutsho kophando lwakutshanje olwenziwe yi-Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES), ukulinganisa imvula ngokufanelekileyo kusetyenziswa iigeyiji zemvula kunokunyusa imveliso yezityalo ukuya kuthi ga kwi-20%, nto leyo echaphazela kakhulu inzuzo yefama.
UGqr. Emily Jans, ingcali yezolimo kwiYunivesithi yaseMelbourne, ugxininisa impembelelo yetekhnoloji kwimisebenzi yezolimo yendabuko. “Ukuqonda iipateni zemvula kubalulekile kubalimi. Ngolwazi oluchanekileyo, banokuqikelela iimfuno zamanzi, banciphise inkunkuma, kwaye bakhethe amaxesha afanelekileyo emisebenzi yasentsimini,” ucacisile. “Iigeyiji zemvula zidlala indima ebalulekileyo ekulawuleni imozulu eyahlukeneyo yase-Australia—ukusuka kwiindawo ezishushu zaseQueensland ukuya kwiindawo ezomileyo zaseNtshona Ostreliya.”
Ukuphucula Ulawulo Lwembalela
Njengoko iOstreliya ijongene neemeko zembalela eziya zisiba mandundu, indima yezixhobo zokulinganisa imvula iye yacaca ngakumbi. Abalimi baxhomekeke kule datha ukwenza izigqibo ezibalulekileyo malunga nokugcinwa kwamanzi, ukukhetha izityalo, kunye nolawulo lwemfuyo. ISebe leMicimbi ePhambili laseNew South Wales libika ukuba ulwazi lwemvula olufike ngexesha luvumela abalimi ukuba baphendule ngokukhawuleza kwiimeko ezomileyo, baqinisekise ukuba bandisa izixhobo zabo kwaye bagcina uzinzo.
Kwimimandla echaphazeleke kakhulu yimbalela, efana neMurray-Darling Basin, abalimi badibanisa iinkqubo zokulinganisa imvula eziphambili kunye nezinzwa zokufuma komhlaba kunye netekhnoloji yokuqikelela imozulu. Le ndlela ibanzi ivumela ulimo olusabelayo noluguquguqukayo olunokumelana noxinzelelo lotshintsho lwemozulu.
Ukuxhasa ukusabela kwiZikhukula
Ngokwahlukileyo koko, iigeyiji zemvula zibaluleke ngokulinganayo kulawulo lwezikhukula kwiindawo zaseOstreliya ezifumana imvula enkulu engaguqukiyo. Idatha echanekileyo yemvula inceda abasemagunyeni ukuba bakhuphe izilumkiso zesikhukula ngexesha elifanelekileyo kwaye bancede abalimi ekwenzeni izicwangciso ezifanelekileyo zongxamiseko zokukhusela izityalo kunye nemfuyo. I-Bureau of Meteorology igxininise indlela iinkqubo zesilumkiso sangaphambi kwexesha ezilinganiswe ngedatha echanekileyo yegeyiji yemvula ezinokusindisa ubomi kwaye zinciphise ilahleko kwezoqoqosho ngexesha leziganeko zemozulu embi.
Imizamo yoLuntu kunye neSayensi yabemi
Ngaphandle kokusetyenziswa kwezikhungo, amanyathelo okubeka esweni imvula asekelwe kuluntu afumene ukuthandwa kulo lonke elasemaphandleni lase-Australia. Iinethiwekhi ezikhokelwa ngokuzithandela zikhuthaza uluntu lwezolimo ukuba luseke iigeyiji zalo zemvula, nto leyo ekhuthaza inkcubeko yentsebenziswano kunye noxanduva olwabelwana ngalo. Kuvele amaqonga afana neRainfall Australia, avumela abalimi ukuba banikele ngedatha yabo, nto leyo ephucula umgangatho kunye nokugubungela ulwazi lwemvula olufumaneka kubo bonke abalimi kummandla othile.
Isiphelo
Njengoko iziphumo zotshintsho lwemozulu ziqhubeka nokuba yimingeni kwezolimo zase-Australia, ukubaluleka kweegeyiji zemvula akunakugxininiswa kakhulu. Ezi zixhobo zibonelela ngedatha ebalulekileyo exhasa ulawulo lwembalela, impendulo yezikhukula, kunye nemveliso yezolimo iyonke. Ngokuqhubeka notyalo-mali kubuchwepheshe bezolimo kunye nokubandakanyeka koluntu, iigeyiji zemvula ziya kuhlala zisisiseko seendlela zolimo ezizinzileyo kulo lonke elase-Australia, zinceda ukukhusela ikamva lezolimo lelizwe ngokuchasene nemozulu engaqinisekanga.
Njengoko abalimi besamkela ezi zixhobo zibalulekileyo, abagcini nje ngokuphucula ukuqina kwabo kodwa bakha nenkqubo yokutya ekhuselekileyo kubo bonke abemi base-Australia. Kule meko itshintsha rhoqo, iigeyiji zemvula azizo nje izixhobo zokulinganisa; ziyindlela yokuphila kubalimi abajongana neepatheni zemozulu ezinzima zelizwekazi elidume ngokugqithisileyo.
