Iintshulube zomhlaba zinokunyusa imveliso yokutya yehlabathi ngeetoni ezili-140 lezigidi ngonyaka

Izazinzulu zaseMelika zifumanise ukuba imibungu yomhlaba inokuba negalelo leetoni ezili-140 zezigidi zokutya kwihlabathi liphela minyaka le, kuquka i-6.5% yeenkozo kunye ne-2.3% yeembotyi. Abaphandi bakholelwa ukuba utyalo-mali kwimigaqo-nkqubo yezolimo kunye neendlela zokusebenza ezixhasa inani lemibungu yomhlaba kunye nokwahlukahlukana komhlaba ngokubanzi kubalulekile ekufezekiseni iinjongo zolimo ezizinzileyo.

Iimpethu zomhlaba zibalulekile ekwakheni umhlaba ophilileyo kwaye zixhasa ukukhula kwezityalo kwiinkalo ezininzi, ezinje ngokuchaphazela ulwakhiwo lomhlaba, ukufunyanwa kwamanzi, ukujikeleza kwezinto eziphilayo, kunye nokufumaneka kwezondlo. Iimpethu zomhlaba zinokuqhuba izityalo ukuba zivelise iihomoni ezikhuthaza ukukhula, zize zincede zikwazi ukumelana neentsholongwane eziqhelekileyo zomhlaba. Kodwa igalelo lazo kwimveliso yezolimo yehlabathi alikakachazwa.

Ukuvavanya impembelelo yemibungu yomhlaba kwimveliso yezityalo ezibalulekileyo kwihlabathi liphela, uSteven Fonte kunye noogxa bakhe abavela kwiYunivesithi yaseColorado State bahlalutye iimaphu zobuninzi bemibungu yomhlaba, iimpawu zomhlaba, kunye nemveliso yezityalo ezivela kwidatha yangaphambili. Bafumanise ukuba imibungu yomhlaba inegalelo malunga ne-6.5% yemveliso yengqolowa yehlabathi (kuquka umbona, irayisi, ingqolowa, nerhasi), kunye ne-2.3% yemveliso yemidumba (kuquka iisoya, iimbotyi, iitshizi, iilentile, kunye ne-alfalfa), elingana neetoni ezingaphezu kwezigidi ezili-140 zeenkozo ngonyaka. Igalelo lemibungu yomhlaba liphezulu kakhulu kumzantsi wehlabathi, linegalelo le-10% kwimveliso yengqolowa kwi-Afrika esezantsi kweSahara kunye ne-8% kwiLatin America nakwiCaribbean.

Ezi ziphumo ziphakathi kwemizamo yokuqala yokulinganisa igalelo lezinto eziphilayo zomhlaba eziluncedo kwimveliso yezolimo yehlabathi. Nangona ezi ziphumo zisekelwe kuhlalutyo lweedathabheyisi ezininzi zasemantla zehlabathi, abaphandi bakholelwa ukuba iimpethu zomhlaba zibalulekile ekuveliseni ukutya kwihlabathi liphela. Abantu kufuneka baphande kwaye bakhuthaze iindlela zolawulo lwezolimo lwendalo, baqinise i-biota yomhlaba wonke, kuquka neempethu zomhlaba, ukuxhasa iinkonzo ezahlukeneyo zendalo ezikhuthaza uzinzo lwexesha elide kunye nokuqina kwezolimo.
