4 izindlela zokuxazulula lendlala emhlabeni

Ngeshwa, akuyona yonke abakhileyo iplanethi yethu kungaba ukukhokhela ukudla kathathu ngosuku. Abaningi akudingeki ukufinyelela imikhiqizo efunekayo, indlala njalo, nokuba on the esengozini yokufa nokuphila. Ungakwenza kanjani lenkinga embulungeni yonke?

izibalo ezithusayo

Ngokwe-UN, indlala ezweni isibe omunye izinkinga acute iningi esintwini yesimanje. Ngokusho ucwaningo kusukela abantu abangaphezu kwezigidi eziyizinkulungwane 7 emhlabeni abacishe babe yizigidi ezingu-870 baphathwa ukungondleki okungamahlalakhona, ingenye eziyisishiyagalombili. nabantu abalambile Iningi lawo lihlala emazweni iminotho kabi athuthukile.

izinto ezimbi Ikakhulukazi ezwekazini lase-Afrika. Ngokusho UN ulinganisela ezingxenyeni ezimaphakathi eningizimu yezwekazi lase kukhona abangondlekile noma ababulawa indlala abantu abangaphezu kwezigidi ezingu-250 - cishe ikota yebahlali bendawo.

Isimanga siwukuthi kodwa le nkinga futhi sisebenza amazwe kuqhathaniswa ochumayo. Kule minyaka eyishumi edlule inani labantu abangondlekile luyanda abantu abangaba yizigidi ezingu-4.

Naphezu inqubekelaphambili enkulu elwa nendlala emhlabeni, lokhu kuyinkinga yembulunga yonke abathintekayo wonke umbuso. isixazululo yayo kubalulekile hhayi nje kuphela kubantu abaswele, kuba njalo isikhuthazo esengeziwe abalimi ubani inikeza ithuba lokukwazi ukuze uthole imali eningi.

Kungenzeka kanjani ukuba banqobe indlala ezweni? Kunezinhlobo ezine yesixazululo ezifanele kakhulu lale nkinga.

Ukwethulwa kwe-biotechnology

Sekungamashumi eminyaka INcwadi Yonyaka emhlabeni wonke kukhona mpikiswano eshubile mayelana nokusetshenziswa nokushintshwa kwezakhi kwezolimo. Naphezu ukuphikisa kusukela ezinhlanganweni ezihlukahlukene zenkolo kanye nomphakathi, kungaba abe insindiso yangempela ngenxa yendlala. Ngokwesibonelo, ukushintsha isakhiwo genetic main izitshalo zokudla - irayisi, ummbila, amazambane, umdumbula - ikuvumela ukuba wenze kubo livikela kakhulu isifo, ukwandisa umkhiqizo wabo futhi uthuthukise umsoco.

Ngaphezu kwalokho, ngokusebenzisa "izitshalo lokugoma" isivuno ukulahleka kungagwenywa yizinambuzane noma izifo. Ngokwesibonelo, Cornell University, i-biotechnology, wakwazi sikhule kabili njengoba fast umdumbula, eyabonakala kakhulu okunomsoco ngokuqhathaniswa nokwangempela.

Yiqiniso, zikhona izingozi ezithile ezihambisana nokusetshenziswa yokushintsha izakhi ezitshalweni. Nokho, kulesi simo, umgomo olungisisa izindlela. Uma une ukukhetha i-biotechnology ukuze ondle sonke isibalo sabantu le planethi, kuyadingeka ukusizakala.

Kumelwe ukhethe phakathi abalimi ukulima ngendlela yezimboni

Namuhla, kunamabandla amabili izinhlobo zezimiso ukudla - ukulima ngendlela yezimboni nezitshalo ezincane (ongumlimi). Ngokusho kwenhlangano ucwaningo NJLL Group, uhlobo lokuqala inzuzo engaphezu kuka-70% womhlaba wokulima nezisetshenziswa. Kodwa konke ekhiqizwa esingaphansi ingxenye yesithathu yazo zonke ukudla emhlabeni. Ngesikhathi esifanayo amapulazi, usebenzisa% 30 kuphela izinsiza, ukwakha lonke ukudla.

Lokhu indida Kulula kakhulu ukuchaza. Ngempela, i-izindawo ezinkulu ayihlwanyelayo omunye imikhiqizo yezilimo uyakuba mkhulu kakhulu uma ziqhathaniswa ngezizathu encane. Nokho, abalimi abancane abasafufusayo bazuze ngokusebenzisa diversification izitshalo, imfuyo kanye parallel ingadi amakilasi. Abakwazi ukukhiqiza ukudla ngenkathi ekunciphiseni isisetshenziswa ukusetshenziswa nokugcina izindleko zokuhamba. Lokhu kusiza hhayi kuphela ukuze silwe kahle kakhulu nendlala emhlabeni, kodwa futhi ukuvimbela kwesimo sezulu esifundeni, futhi isekela izinhlobonhlobo zezinto eziphilayo ezinkulu. Futhi okubaluleke nakakhulu, ukuthi izindlela eziphumelelayo ezinjalo lungasetshenziswa e emikhulu amabhizinisi ezolimo ngempumelelo.

Ukuqeqesha abalimi izindlela kahle yokulima

Ngeshwa, abalimi abaningi bamane nje akazi lutho izindlela ezintsha ngempumelelo izitshalo ezikhulayo. Uma uchitha isikhathi nabo ukuqwashisa, isibonelo, izindlela ezintsha zokuthola izinsuku ukutshala ilayisi, ukwethulwa umquba ehlukile noma ukusetshenziswa kohlobo olusha imbewu, umkhiqizo wabo kungaba ngcono kakhulu.

Indlela elula kakhulu ukusiza abalimi besebenzisa inhlangano Indian Digital Green. It ubeka lonke ulwazi ngesimo amavidiyo ku-YouTube. usizo okunjalo kwenza abalimi bakwazi ukwandisa imikhiqizo ukudla, ngenxa yalokho akubona kuphela okwandisa umcebo wakhe, kodwa futhi ekuthuthukiseni umnotho wendawo.

ezolimo Urban

Izinga yokuphila yasedolobheni zomhlaba Kancani-kancani ikhula. Wayeke azifinyelelanga ezingeni 25%. Kulokhu, iningi ukudla livela yokulima engaphandle imikhawulo edolobheni, abenze ezibizayo.

Eqinisweni, ukudla zingatshalwa emadolobheni. Ngenxa yale njongo, efanelekayo bophahla, izingadi namapaki. Kuzwakala kancane emibonweni yami, kodwa eqinisweni ngempela ngempela.
