Ngokumelene nokwasemuva kwemithombo yamanzi yomhlaba wonke eya ngokuya iqinile, izinzwa ezingase zibe khona emanzini, njengethuluzi elibalulekile lobuchwepheshe bezolimo, zidlala indima ebaluleke kakhulu emapulazini emhlabeni jikelele. Kusukela ezivinini eCalifornia, eU.SA kuya emapulazini ahlangene kwa-Israel, kusukela emasimini ekhofi e-Brazil kuya emasimini kakolo e-Australia, lo mshini okwazi ukukala ngokunembile ukushuba kwamanzi enhlabathini usiza abalimi ukuphatha ukuchelela ngokwesayensi kakhulu futhi bazuze ukusetshenziswa kahle kwemithombo yamanzi.
I-United States: Ukunisela ngokunemba kuthuthukisa ikhwalithi yewayini
Esifundeni esidumile sewayini eNapa Valley, eCalifornia, izinzwa ezingase zibe namanzi enhlabathini ziguqula indlela evamile yokuphatha isivini. Abenzi bewayini basebenzisa la madivaysi ukuze baqaphe izimo zokuswakama kwezingqimba zenhlabathi ezihlukene futhi balawule ngokunembile isikhathi nomthamo wokunisela.
“Ngokugcina amanzi angcono kakhulu enhlabathini, asikwazi nje ukonga u-30% wamanzi okunisela, kodwa futhi sithuthukise ibhalansi ye-sugar-acid yamagilebhisi,” kusho umphathi wezolimo wesitolo sewayini sesitolo sendawo. "Lokhu kubonakala ngokuqondile enkingeni yokunambitheka kwewayini, okwenza imikhiqizo yethu ikwazi ukuncintisana emakethe."
I-Israel: Imodeli yezobuchwepheshe yezolimo zasogwadule
Njengomholi wembulunga yonke ekuphathweni kwemithombo yamanzi, i-Israel isebenzise kabanzi izinzwa ezingase zibe namanzi enhlabathini ezinhlelweni zayo zokunisela zokuthonta. Ezindaweni zezolimo zase-Negev Desert, lezi zinzwa zixhunywe kumasistimu okulawula okuzenzakalelayo ukuze kuzuzwe ukunisela okunembayo okusekelwe ngokuphelele ezidingweni zezitshalo.
“Uhlelo lwethu lungaqala ukunisela ngokuzenzakalelayo lapho amanzi enhlabathini efika endaweni ethile,” kwethula uchwepheshe wezobuchwepheshe bezolimo. “Le” modeli yokuphakelwa kwamanzi lapho kudingeka khona isenza sikwazi ukugcina umkhiqizo ophezulu ngisho nasezindaweni ezomile kakhulu, nezinga lokusebenzisa imithombo yamanzi lifinyelela ku-95%.
IBrazil: Ukuvikela amahlathi emvula ngenkathi kukhulisa ukukhiqizwa
Emasimini ekhofi nezomoba esifundeni saseCerrado eBrazil, ukusetshenziswa kwezinzwa ezingase zibe khona zamanzi enhlabathini kusiza abalimi ukuba balinganisele ubudlelwano phakathi kokukhiqizwa kwezolimo nokuvikelwa kwemvelo. Ngokuqapha kahle izinguquko zokuswakama komhlabathi, abalimi bangagwema ukuchelela ngokweqile, banciphise ukulahleka kwezakhi kanye nokungcoliswa kwamanzi angaphansi komhlaba.
“Asisancikile ezinhlelweni zokunisela ngenkasa okungaguquki kodwa senza izinqumo ngokusekelwe emininingwaneni yezinzwa,” kusho umphathi wepulazi elikhulu lekhofi. "Lokhu akwehlisi nje kuphela ukusetshenziswa kwamanzi ngo-20%, kodwa futhi kwandisa ukukhiqizwa ngo-15%, kuyilapho kunciphisa umthelela omubi endaweni ezungezile."
I-Australia: Izixazululo Ezihlakaniphile Zokubhekana Nesimo Sezulu Esigwazayo
Bebhekene nezimo zezulu zesomiso ezivamile, abalimi base-Australia bathatha ngenkuthalo izinzwa ezingase zibe namanzi enhlabathini ukuze basebenzise kahle imithombo yamanzi. Emapulazini akolweni eNew South Wales, lezi zixhobo zisiza abalimi ukuthi baqinisekise ukuthi izitshalo zithola inani elifanele lamanzi ngesikhathi sezigaba ezibucayi zokukhula, kuyilapho zigwema ukumoshwa kwemithombo yamanzi ayigugu ngezikhathi ezingabalulekile.
“Ngaphansi kwezimo zemvula engaqinisekile, wonke amaconsi amanzi ayigugu,” kusho umlimi. “Imininingwane engase ibe namanzi omhlaba isenza sikwazi ukunikeza inani elifanele lamanzi ngesikhathi esifanele, okubalulekile ekugcineni inzuzo yepulazi.”
I-India: Izicelo Ezintsha Zomnotho Wabalimi Abancane
Ngisho naseNdiya, lapho ukulima kwezinga elincane kuwumnotho ohamba phambili, izinzwa ezingase zibe namanzi enhlabathini zithole amamodeli ohlelo olusha. E-Punjab, amapulazi amancane amaningi abelana ngesistimu yezinzwa futhi athola iziphakamiso zokunisela ngamaselula, ajabulela izinzuzo zobuchwepheshe bezolimo obunembayo ngezindleko eziphansi.
“Ngeke sikwazi ukukhokhela uhlelo lokuchelela olukhaliphile, kodwa izinsiza zokuzwa ngokuhlanganyela ziyenzeka,” kusho inhloko yokubambisana yabalimi bendawo. “Lokhu kusisize ukuthi sehlise ugesi ompompa amanzi ngo-25% ngesikhathi sikhuphula isivuno.”
Ingqikithi yobuchwepheshe: Kusukela kudatha kuye ekwenzeni izinqumo
Izinzwa zesimanje ezingase zibe namanzi enhlabathini, ngokusekelwe ezimisweni zama-tensiometer noma izinzwa eziqinile, zingakala ngokunembile ukuthi izimpande zezitshalo zimunca kanjani amanzi emhlabathini. Le datha, uma ihlanganiswa namamodeli okukhula kwezitshalo, inganikeza abalimi ukwesekwa kwezinqumo eziqondile zokunisela.
“Isihluthulelo asikona nje kuphela ukulinganisa amandla amanzi enhlabathini, kodwa futhi nasekuguquleni le datha ibe iziphakamiso zokuphatha ezinokwenzeka,” kusho umqondisi wocwaningo nentuthuko wenkampani yezobuchwepheshe bezolimo. "Sizibophezele ekwakheni ama-algorithms ahlakaniphile ukuze sihlanganise idatha engase ibe khona emanzini kanye nezibikezelo zesimo sezulu, izigaba zokukhula kwezitshalo nolunye ulwazi, sinikeze ukwesekwa kwezinqumo ezibanzi."
I-future Outlook: I-Global Promotion kanye Nokusungulwa Kwezobuchwepheshe
Ngokudlondlobala kokuguquguquka kwesimo sezulu emhlabeni wonke kanye nenkinga enkulu yokushoda kwamanzi, ukusetshenziswa kwezinzwa ezingase zibe khona emanzini kulindeleke ukuthi kuqhubeke ukwanda. Abacwaningi bakha izinzwa ezingambi eqolo futhi ezihlala isikhathi eside ukuze zihlangabezane nezidingo zabalimi abasafufusa emazweni asathuthuka.
“Izinzwa ezingase zibe khona zamanzi enhlabathini esikhathini esizayo zizohlakanipha futhi zixhunywe kunethiwekhi,” kubikezela umhlaziyi wezimboni. "Bazosebenza ngokuzimela iminyaka eminingana ngaphandle kokulungisa futhi baxhunywe ngamanethiwekhi asebenzisa amandla amancane ukuze bakhe inethiwekhi yokulawula amanzi ehlanganisa ipulazi lonke."
Kusukela emapulazini asezingeni eliphezulu emazweni athuthukile kuya ezindaweni zamapulazi ezivamile emazweni asathuthuka, izinzwa ezingase zibe namanzi enhlabathini ziguqula indlela imithombo yamanzi yezolimo ephathwa ngayo emhlabeni wonke. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe kanye nokwehla okuqhubekayo kwezindleko, leli thuluzi lokunisela elinembile kulindeleke ukuthi libambe iqhaza elibaluleke kakhulu ekuvikelekeni kokudla emhlabeni wonke kanye nokuphathwa kwemithombo yamanzi esimeme, ukuhlinzeka ngezixazululo ezingokoqobo nezingenzeka enkingeni yamanzi yomhlaba wonke.
