Sonke siyazi ukuthi ukudla kubalulekile ukuze siphile. Kodwa wake wacabanga nje ukuthi, eminyakeni engama-20 noma engama-30 ezayo, kuyoba nokudla okwanele kuwo wonke umuntu kuleli zwe? Lokhu kuyinto sonke okudingeka siyicabangele. Ngoba inani labantu emhlabeni liyanda usuku nosuku. Ngakho-ke umhlaba wethu uzokwazi yini ukondla wonke umuntu? Sikhuluma ngalesi sihloko esibaluleke kakhulu namuhla.
Kungani izindlela zokulima zamanje zinganele?
Kalula nje, inkinga iphakathi kokufunwa kanye nokunikezwa. Ngokusho kochwepheshe, ngo-2050, kuzodingeka sikhiqize ukudla okungaphezu kuka-56% kunalokho esakwenza ngo-2010, noma ngaphezu kwengxenye. Cabanga ukuthi lokho kukhulu kangakanani.
Akunakwenzeka ukufeza lo mgomo ngokusebenzisa izindlela zokulima zamanje. Kodwa-ke, kuza nezindleko ezinkulu zemvelo. Okusho ukuthi, uma siqhubeka nokulima ngale ndlela, sizobangela umonakalo ongabekezeleleki endaweni yethu, emithonjeni yamanzi, kanye nomhlaba.
Umthelela wokukhiqizwa kokudla emhlabeni jikelele emvelweni usuvele ubalulekile. Ama-70% okusetshenziswa kwamanzi ahlanzekile emhlabeni aya kwezolimo. Ngokufanayo, ama-26% okukhishwa kwamagesi okushisa umhlaba abangelwa inqubo yokukhiqizwa kokudla.
Uma siqhubeka kanje, eminyakeni embalwa sizosala nendawo engcolile, engenanhlabathi evundile yokuyilima, engenamanzi ahlanzekile okuphuza. Ngakho-ke, ikhambi lale nkinga ukushintsha indlela esilima ngayo. Kufanele sithuthukise ubuchwepheshe, kunokuba sinamathele ezindleleni ezindala.
Ngakho-ke siyini ikhambi? Ezolimo zesikhathi esizayo sezifikile!
Kodwa asikho isidingo sokwesaba. Ososayensi nochwepheshe bezolimo emhlabeni wonke bathola izindlela ezintsha nezisimeme zokubhekana nale nselele. Ezinye zalezi zingase zizwakale njengezinto zesayensi eqanjiwe, kodwa ziyikusasa lomhlaba wethu.
1. Ukulima Okuqondile
Cabanga... esikhundleni samahektha ayizinkulungwane zamasimu elayisi noma amasimu emifino, izitshalo zitshalwa ngaphakathi kwesakhiwo esikhulu phakathi nedolobha, amashalofu ngamashalofu, njengamashalofu esitolo esikhulu.
Ngale ndlela, imvelo ilawulwa ngokuphelele.
- Esikhundleni sokukhanya kwelanga: Amabhalbhu akhethekile e-'LED' anikeza ukukhanya okudingekayo ezitshalweni.
- Umanyolo namanzi: Isitshalo ngasinye sinikezwa inani elidingekayo lehla ngehla. Lokhu kunciphisa imfucuza yamanzi cishe ngo-95%.
- Izibulala-zinambuzane: Ngenxa yendawo elawulwayo, umonakalo wezinambuzane uphansi kakhulu. Ngakho-ke, ukusetshenziswa kwezibulala-zinambuzane ngokuvamile akudingeki.
Enye inzuzo yale ndlela ukuthi ingatshalwa unyaka wonke, ngaphandle kokukhathazeka ngesimo sezulu. Futhi, njengoba lezi zingatshalwa eduze kwamadolobha, izindleko zokuhamba kanye nokungcola kwemvelo kuyancipha.
2. Ezolimo Eziqondile
Leli yikusasa lokulima. Kalula nje, kusho ukuphatha ingxenye ngayinye yensimu, futhi ngezinye izikhathi isitshalo ngasinye, ngokwehlukana, esikhundleni sokuphatha yonke insimu ngendlela efanayo.
Ubuchwepheshe obusezingeni eliphezulu buyasiza kulokhu.
- Ama-drone: Ama-drone athunyelwa emasimini ukuze athathe izithombe ezisezingeni eliphezulu zempilo yensimu, umswakama wenhlabathi, kanye namazinga wezakhamzimba.
- Izinzwa: Izinzwa ezifakwe kuyo yonke insimu kanye nasemishinini efana nama-tractor ziqoqa idatha yesikhathi sangempela mayelana nezimo zenhlabathi kanye nokukhula kwezitshalo.
- Ubuhlakani Bokwenziwa (AI): Ngokuhlaziya lolu lwazi oluqoqiwe, i-AI ikutshela ngqo ukuthi hlobo luni lwamanzi oludingekayo ensimini, ukuthi yiziphi izindawo ezidinga umanyolo owengeziwe, nokuthi isifo singavela kuphi.
Bese besebenzisa imishini ezenzakalelayo, bafaka okudingekayo, lapho kudingeka khona, futhi ngenani elifanele . Cabanga nje, kufefa ukhula oluncane kuphela lapho kukhona khona ukhula. Hhayi ensimini yonke. Ngenxa yalokhu, ukusetshenziswa komanyolo, amanzi, kanye nezibulala-zinambuzane kuncipha kakhulu. Isivuno siyanda. Futhi umonakalo emvelweni nawo uyancishiswa.
| Isici | Ukulima kwendabuko | Ezolimo Eziqondile |
|---|---|---|
| Ukusetshenziswa kwamanzi nomanyolo | Isetshenziswa ngokulinganayo kuyo yonke indawo yezitshalo. Ngokuvamile kuba nodoti omningi. | Ngokusekelwe kudatha, inani elidingekayo kuphela elisetshenziswa lapho kudingeka khona. Ukulahlwa kwemfucuza kuncane kakhulu. |
| Ukuvuna | Isivuno singahluka kuye ngezindawo endaweni etshaliwe. | Ingxenye ngayinye iphathwa kahle, okuholela ekuvuneni okuphezulu nokulinganayo. |
| Umthelela kwezemvelo | Ukusetshenziswa ngokweqile komanyolo kanye nezibulala-zinambuzane kungangcolisa imithombo yamanzi kanye nenhlabathi. | Ukusetshenziswa kwamakhemikhali angadingekile kuncane kakhulu, ngakho-ke umonakalo emvelweni mncane kakhulu. |
| ukwenza isinqumbo | Ngokusekelwe kokuhlangenwe nakho komlimi kanye nokubona okuvamile. | Kususelwa kudatha yesikhathi sangempela kanye nokuhlaziywa kobuchwepheshe. |
3. Yeka ukulahlwa kokudla!
Kungakhathaliseki ukuthi sikhiqiza ukudla okungakanani, akunandaba ukuthi inani elikhulu lakho liphelela emfucumfucwini. Inani elikhulu lokudla liyachithwa endleleni esuka epulazini iya esitsheni sethu. Njengesixazululo salokhu, "ukupakisha okuhlakaniphile" kulindeleke ukuthi kufike esikhathini esizayo.
La maphakheji angasitshela ukuthi ukudla okungaphakathi kuzokonakala nini ngokushintsha umbala. Ezinye izinto zokupakisha zingagcina ukudla kusha isikhathi eside. Izinto ezintsha ezifana nalezi zinganciphisa imfucuza yokudla, okufana nokwandisa ukukhiqizwa kokudla.
Umlayezo Wokuya Nawe Ekhaya
- Njengoba inani labantu emhlabeni landa, sizodinga ukudla okwengeziwe esikhathini esizayo kunamanje.
- Izindlela zezolimo zendabuko ezikhona azihlali isikhathi eside ngoba zibangela umonakalo omkhulu emvelweni.
- Izindlela ezintsha ezisekelwe kubuchwepheshe ezifana nokulima ngokuqondile kanye nokulima ngokunemba kungaveza isivuno esikhulu kusetshenziswa izinsiza ezimbalwa.
- Lezi zindlela ezintsha zizonciphisa umonakalo emvelweni futhi zisinikeze sonke ukudla okunempilo.
- Ukunciphisa imfucuza yokudla nokwandisa umkhiqizo kubaluleke ngendlela efanayo ekuphepheni kokudla esikhathini esizayo.
