Kua kitea e ngā kaipūtaiao o Amerika e 140 miriona tana kai pea te koha mai i ngā kutukutu whenua puta noa i te ao i ia tau, tae atu ki te 6.5% o ngā witi me te 2.3% o ngā pīni. E whakapono ana ngā kairangahau he mea nui te haumi ki ngā kaupapa here me ngā mahi ahuwhenua taiao e tautoko ana i ngā taupori kutukutu whenua me te kanorau o te oneone whānui hei whakatutuki i ngā whāinga ahuwhenua pumau.
He mea nui ngā noke whenua hei hanga i te oneone hauora, ā, he tautoko i te tipu o ngā tipu i roto i ngā āhuatanga maha, pērā i te pānga ki te hanganga o te oneone, te kohi wai, te huringa o ngā mea rauropi, me te wātea o ngā matūkai. Ka taea hoki e ngā noke whenua te akiaki i ngā tipu ki te whakaputa i ngā homoni whakatairanga tipu, hei āwhina i a rātou ki te ātete i ngā mate pāwera noa o te oneone. Engari kāore anō kia inehia tā rātou takoha ki te whakaputanga ahuwhenua o te ao.
Hei aromatawai i te pānga o ngā kutukutu whenua ki te whakaputanga hua nui o te ao, i tātarihia e Steven Fonte me ōna hoa mahi mai i te Whare Wānanga o Colorado State ngā mahere o te nui o ngā kutukutu whenua, ngā āhuatanga o te oneone, me te whakaputanga hua mai i ngā raraunga o mua. I kitea e rātou ko ngā kutukutu whenua e whai wāhi ana ki te 6.5% o te whakaputanga witi o te ao (tae atu ki te kānga, te raihi, te witi, me te parei), me te 2.3% o te whakaputanga pīni (tae atu ki te pīni soya, te pī, te pīni tīhi, te rēneti, me te alfalfa), he rite ki te neke atu i te 140 miriona tana o te witi ia tau. He tino nui te takoha a ngā kutukutu whenua i te tonga o te ao, e whai wāhi ana ki te 10% ki te whakaputanga witi i Awherika ki te tonga o te Sahara me te 8% i Amerika Latina me te Karipiana.
Ko ēnei kitenga kei roto i ngā whakamātautau tuatahi ki te ine i te takoha a ngā rauropi oneone whai hua ki te whakaputanga ahuwhenua o te ao. Ahakoa i ahu mai ēnei kitenga i te tātari i ngā maha o ngā pātengi raraunga raki o te ao, e whakapono ana ngā kairangahau he mea nui ngā kutukutu whenua ki te whakaputanga kai o te ao. Me rangahau, me whakatairanga hoki te tangata i ngā mahi whakahaere ahuwhenua rauropi, me whakapakari i te koiora oneone katoa, tae atu ki ngā kutukutu whenua, hei tautoko i ngā ratonga rauropi maha e whakatairanga ana i te pumau mo te wā roa me te manawanui ahuwhenua.
