Isifinyezo sokuqonda

Ukulima okuqondile, indlela entsha kwezolimo, sekumi ngomumo ukuguqula indlela esitshala ngayo ukolweni, okuhlinzeka ngesixazululo ekwandeni kwesidingo sokudla kanye nezinselelo ezibangelwa ukuguquka kwesimo sezulu. Le ndlela, engakhuphula kakhulu isivuno futhi inikeze izinzuzo ezinjengokusetshenziswa kancane komhlaba, izimo ezikhulayo ezilawulwayo, kanye nokusetshenziswa kabusha kwamanzi, ingaholela ohlotsheni lwezolimo olusebenza kahle futhi oluzinzile. Njengoba lolu shintsho lwenzeka, ngeke luthinte abalimi kuphela, okuzodingeka bathole amakhono amasha, kodwa nasezindaweni zasemadolobheni, lapho ukulima okuqondile kungadala amathuba emisebenzi, kuthuthukise ukuvikeleka kokudla, futhi kugqugquzele intuthuko yezobuchwepheshe.

Ingqikithi yokulima eqondile

Amapulazi endabuko angase angabe esaba indawo engcono kakhulu yokutshala ukolweni. Ukuqanjwa okusha kwesayensi yezolimo nobuchwepheshe kwenza izindlela ezintsha zokukhula ezisebenzisa kahle kakhulu izinyathelo zepulazi. Njengoba inani labantu emhlabeni wonke liqhubeka nokukhula kanye nokushintsha kwesimo sezulu kunciphisa umhlaba otholakalayo wokulima, ukwanda kwesivuno sezolimo kuya ngokuya kuba inselele enkulu kwezolimo ekhulwini lama-21. 

Le nselelo iyiqiniso ikakhulukazi ezitshalweni zikakolweni nokusanhlamvu, ezihlinzeka ngengxenye eyodwa kwezinhlanu zamakholori namaprotheni okudla kwabantu emhlabeni wonke futhi okuyisitoko esibalulekile sokulima kwezilwane. Ngenhlanhla, ukuthuthuka okusheshayo kwemisebenzi yokulima ukolweni oqondile kungase kube nomthelela omkhulu ezivunweni zesikhathi esizayo.

Ngokwezilinganiso ezihlukahlukene, ukulima okuqondile kungakhuphula ihektha lesivuno sikakolweni phakathi kuka-220 no-600 izikhathi. Ngaphezu kwalokho, ukwakhiwa kwezindawo ezima mpo kungathola ukonga kanye nezinzuzo eziningi, okuhlanganisa ukusetshenziswa komhlaba omncane kunokolo otshalwe ensimini, ukulawula izimo ezikhulayo, ukuphinda kusetshenziswe amanzi amaningi, ukungabandakanyi izinambuzane nezifo, kanye nokungabikho kokulahlekelwa kwezakhi. imvelo.

Umthelela ophazamisayo 

Njengoba amanani amandla ehla, mhlawumbe ngenxa yokwenyuka kokusetshenziswa kwemithombo evuselelekayo noma ama-reactors ahlanganisiwe, abalimi bakakolweni bangathola ukulima mpo kuyinketho ekhangayo. Lokhu kushintshwa kungase kuholele ekusetshenzisweni kahle komhlaba, okuvumela abalimi ukuthi bahlukanise izindlela zabo zokulima. Isibonelo, umhlaba osindisiwe ekulinyweni kukakolweni wendabuko ungase uphinde usetshenziswe eminye imisebenzi yezolimo, njengokufuywa.

Ukushintshela ekulimeni okuqondile kuphinde kusho uguquko kusethi yamakhono adingekayo ekulimeni. Abalimi kuzodingeka bathole ulwazi olusha namakhono ukuze basebenzise la mapulazi amile ngendlela efanele, okungase kuholele ekwandeni kwezinhlelo zemfundo nokuqeqesha ezihambisana nalolu hlobo olusha lwezolimo. Lolu shintsho lungase futhi lukhuthaze ukukhula kwemisebenzi emkhakheni wezolimo, ikakhulukazi ekuphathweni nasekunakekeleni ukulima okuqondile.

Ngaphezu kwalokho, amathuba okuthi ukulima okuqondile kusetshenziswe ezindaweni zasemadolobheni kungaba nomthelela omkhulu emadolobheni nakubahlali bawo. Ukulima okuqondile emadolobheni kungaholela ekudaleni imisebenzi emisha ngaphakathi kwemingcele yedolobha, okunomthelela emnothweni wendawo. Kungase futhi kuthuthukise ukuvikeleka kokudla ngokunciphisa ukuthembela emaketangeni okunikezela amabanga amade. Kohulumeni, lokhu kungasho ukushintsha ekugxilweni kwenqubomgomo ekusekeleni izinhlelo zezolimo zasemadolobheni, kuyilapho ezinkampanini, kungavula izindlela ezintsha zokutshala izimali kanye nokusungula ubuchwepheshe bokulima emadolobheni.

Imithelela yokulima okuqondile

Imithelela ebanzi yokulima okuqondile ingabandakanya:

• Inani elizinzile, elingaguquki lezolimo lezitshalo elivikelwe ekuphazanyisweni kwezehlakalo zesimo sezulu kanye nezinguquko futhi ezingenazo izibulala-zinambuzane nezibulala-khula. (Lokhu kuzosiza ukuvikela ukutholakala kokudla kwezwe.)
• Izitshalo ezingavamile noma ezingezona ezomdabu emazweni angeke asekele ukukhula kwazo.
• Ukulungiswa kabusha kwezakhiwo zasemadolobheni ezikhona nezingasetshenziswa kancane zibe amapulazi endawo, ngaleyo ndlela kuncishiswe ukungcoliswa kwemvelo ngokunciphisa izindleko zokuhamba ukusuka epulazini kuya kumthengi wokugcina.
• Ama-molecule asebenzayo ezinto ezisetshenziswayo zezokwelapha ezikhona nezizayo.
• Ukushintsha kokushintshashintsha kwabantu, abantu abaningi bekhetha ukuhlala ezindaweni zasemadolobheni ngenxa yokutholakala kwemikhiqizo emisha, etshalwa endaweni.
• Ubuchwepheshe obusha bokusebenzisa amandla ngendlela efanele kanye nokulawulwa kwesimo sezulu emapulazini aqondile, okuholela ekwandeni komkhakha wezobuchwepheshe bezolimo.
• Ukwanda kwesidingo sabasebenzi abanamakhono abakwazi ukusebenza futhi bagcine izinhlelo zokulima zimile.
• Ukunciphisa ubunzima emithonjeni yemvelo ngokusebenzisa amanzi amancane kanye nomhlabathi uma kuqhathaniswa nezindlela zokulima zendabuko, okuholela ohlotsheni oluzinzile lwezolimo.
• Izinqubomgomo nemithethonqubo emisha yokweseka lolu hlobo lwezolimo okuholela ekushintsheni ekugxilweni kwenqubomgomo yezolimo.

Imibuzo okufanele icatshangelwe

• Ucabanga ukuthi ukulima okuqondile kuzobona nini ukutholwa okugcwele ngaphakathi embonini yezolimo?
• Kungenjalo, ucabanga ukuthi izinzuzo zokulima zibheke phezulu zeqile?
