Njengoba imithombo yamanzi yomhlaba wonke iba nzima kakhulu, ubuchwepheshe bokunisela kwezolimo bushintsha kakhulu. Ucwaningo lwakamuva lubonisa ukuthi uhlelo lokunisela olunembile olusekelwe eziteshini zezulu zezolimo ezihlakaniphile lungasiza abalimi ukuthola inzuzo enkulu yokongiwa kwamanzi okungu-30% kanye nokwanda komkhiqizo okungu-20%. Lobu buchwepheshe obusha buchaza kabusha amazinga okunisela ezolimo zanamuhla.
Iziteshi zezulu ezihlakaniphile zingaba kanjani “ubuchopho obuhlakaniphile” bezindawo zokulima
Emasimini anamuhla, iziteshi zezulu zezolimo sezibe yimishini ehlakaniphile ebaluleke kakhulu.
Isimiso sobuchwepheshe: Ukwenza izinqumo ezinembile ezisekelwe kudatha
Isiteshi sesimo sezulu esihlakaniphile sezolimo siqoqa idatha yesikhathi sangempela mayelana nemvelo yamapulazi ngezinzwa eziningi, kufaka phakathi izingxenye ezibalulekile ezifana "nenzwa yomswakama womhlabathi", "isiqaphi semvula", "isivinini somoya kanye nemitha yokuqondisa", "inzwa yemisebe esebenzayo ngokwenziwa kwe-photosynthesis" kanye "neprobe yokushisa nomswakama".
“Ukunisela ngokwendabuko kuvame ukusekelwe kokuhlangenwe nakho hhayi kudatha,” kusho uSolwazi Zhang, uchwepheshe wesimo sezulu kwezolimo. “Kodwa-ke, iziteshi zesimo sezulu ezihlakaniphile zinganikeza idatha yemvelo enembile kumitha yesikwele, zitshele abalimi ukuthi banisele nini ‘nokuthi’ banisele malini’, okufeza ngempela ukuhlinzekwa kwamanzi lapho kudingeka.”
Umphumela wokusetshenziswa okusebenzayo uyamangalisa
Esizindeni sokutshala imifino eThailand, kuye kwaba nempumelelo emangalisayo ngemva kokwamukelwa kohlelo lwesiteshi sezulu esihlakaniphile. “Ngaphambilini, besinisela ngokuzwa, kodwa manje sithembele kudatha,” kusho uMaster Li, umlimi omkhulu. “Lolu hlelo lushukumisa ngokuzenzakalelayo isikhathi kanye nenani lokunisela. Ekupheleni konyaka, sesisindise ingxenye yesithathu yebhili lamanzi, futhi isivuno sikhuphuke ngo-20% esikhundleni salokho.”
Idatha ikhombisa ukuthi i-mu ngayinye yomhlaba kulesi sisekelo isindisa cishe ama-cubic metres ayi-120 amanzi minyaka yonke, umkhiqizo wemifino ukhuphuka ngo-15% kuya ku-20%, futhi ikhwalithi nayo ithuthuke kakhulu.
Umqondisi uWang we-Technology Extension Center yoMnyango Wezolimo ukhombe ukuthi: “Ngokwehla kwezindleko zezinzwa kanye nokwanda kobuchwepheshe be-Internet of Things, iziteshi zezulu ezihlakaniphile zisakazeka kusukela emapulazini amakhulu kuya kubalimi abancane nabaphakathi.” Uhulumeni uphinde washeshisa le nqubo ngezinqubomgomo zoxhaso zokusekela ezolimo ezonga amanzi kanye nesu likazwelonke lokuphepha kokudla.
Umbono Wesikhathi Esizayo
Ngokuhlanganiswa kwe-5G, ubuhlakani bokwenziwa kanye nobuchwepheshe be-cloud computing, iziteshi zezulu zezolimo ziyathuthuka ziye ekuhlakanipheni okukhulu nasekuqondeni. Ochwepheshe babikezela ukuthi eminyakeni emithathu ezayo, izinga lokumbozwa kwezwe lonke lokunisela okuhlakaniphile kulindeleke ukuthi likhuphuke lisuka ku-15% lamanje liye ngaphezu kuka-40%, okuhlinzeka ngosekelo lobuchwepheshe olubalulekile lokuqinisekisa ukuphepha kokudla kuzwelonke kanye nokusetshenziswa okusimeme kwemithombo yamanzi.
