Mwachiwonekere, vuto lalikulu ndi kudyetsa 33% amuna ochulukirapo ndi zinthu zomwezo monga pano. Masiku ano, tikudziwa kuti vutoli silikudalira kwambiri kupezeka kwa zinthu monga kugawa kwawo padziko lonse lapansi komanso kuwononga. Chifukwa chake, 30% yazakudya zapadziko lonse lapansi zimatayika pambuyo pokolola kapena kutayika m'masitolo, m'nyumba kapena m'malo operekera zakudya.¹. Kuphatikiza apo, mbewu zambiri ndi malo amaikidwa pambali kuti aziweta ziweto m’malo molima mbewu.². Chotsatira chake, zikuwoneka kuti ndizofunikira kuganiziranso zaulimi kuti zigwirizane ndi zolinga zonse za chilengedwe - kupulumutsa madzi, kuchepetsa mpweya woipa wowonjezera kutentha, kuipitsidwa, zinyalala - ndi zoneneratu za chiwerengero cha anthu.

Kupititsa patsogolo kawetedwe ka ziweto

Kuti ziŵeto ziwonjezeke mosalekeza, cholinga chake ndi kupanga nyama yochuluka pogwiritsa ntchito chakudya chochepa. Pachifukwa ichi, amalangizidwa kuti apange mitundu ya ng'ombe yomwe imakhala yochuluka kwambiri mu nyama ndi mkaka. Masiku ano, pali kale nkhuku zomwe zimatha kulemera kwa 1,8 kg ndi 2,9 kg ya chakudya chokha, kutembenuka kwa 1,6, kumene nkhuku yeniyeni iyenera kudya 7,2 kg.². Cholinga chake ndikuchepetsa kutembenuka uku kukhala 1,2 kuti phindu liwonjezeke komanso kuchepera kwa mbewu monga chimanga.

Komabe, njira ina iyi imabweretsa zovuta zamakhalidwe: ogula amakhudzidwa kwambiri ndi zomwe nyama zimawayambitsa ndipo akuwonetsa chidwi chokulirapo pakuweta moyenera. Amateteza moyo wabwino wa zinyama m'malo mwa ulimi wa batri, komanso zakudya zathanzi. Makamaka, izi zingathandize kuti nyama zisamapanikizike kwambiri ndipo motero zimatulutsa nyama yabwino.³. Komabe, madandaulowa amafunikira malo, kutanthauza kuti oweta akwera mtengo - ndipo mtengo wogulitsa - ndipo sizigwirizana ndi njira yoweta kwambiri.

Chepetsani kuonongeka ndi kuwononga chilengedwe popanga mitundu yabwino ya zomera

Kusintha kwa zomera zina kungathandize kuti ulimi ukhale wosaipitsa komanso wopindulitsa. Mwachitsanzo, popanga mpunga wosiyanasiyana umene sumva kwambiri mchere, kuwonongeka kungachepe pakachitika tsunami ku Japan.⁴. Momwemonso, kusintha kwa majini kwa zomera zina kumapangitsa kuti zitheke kugwiritsa ntchito feteleza wocheperapo, motero kutulutsa mpweya wowonjezera kutentha kwinaku mukusunga ndalama zambiri. Cholinga chingakhale kupanga mitundu ya zomera zomwe zimatha kutenga nayitrogeni - feteleza kuti akule - mumlengalenga ndikukonza.². Komabe, mwina sitingakwaniritse izi kwa zaka pafupifupi makumi awiri zokha, koma zoyesererazi zitha kukhala pachiwopsezo chotsutsana ndi malamulo oletsa (makamaka ku Europe) okhudzana ndi zamoyo zosinthidwa ma genetic. Zowonadi, palibe kafukufuku wanthawi yayitali yemwe wawonetsabe kusavulaza kwawo thanzi lathu. Komanso, njira iyi yosinthira chilengedwe imakhala ndi zovuta zowonekeratu.
