Masomphenya ambiri omwe alimi angakhale olakwika ndi osochera.

"Chakudya choyenera chiyenera kuwirikiza kawiri ndi 2050 kuti chidyetse anthu akukula padziko lapansili." Chisokonezo ichi chabwerezedwa mobwerezabwereza m'zaka zaposachedwa kuti chadziwika bwino pakati pa asayansi, ndale ndi alimi, koma tsopano ochita kafukufuku akutsutsa mfundo iyi ndikukonzekera masomphenya atsopano a zaulimi.

Kafukufuku wofalitsidwa mu Bioscience akuwonetsa kuti ulimi udzafunika kuwonjezeka kuchokera pa 25 mpaka 70 peresenti kuti ukwaniritse zofuna za zakudya mu 2050. Malingaliro akuti tikufunika kuwirikiza kawiri kuchulukitsa kwa mbeu ndi zinyama pofika chaka cha 2050 sichikugwirizana ndi deta, malinga ndi Mitch Hunter, katswiri wodziwika bwino wa agronomy, ku Penn State College of Agricultural Sciences. Malingana ndi iye, kufufuzaku kukuwonetsa kuti kupanga kupitilira kuwonjezeka, koma osati mofulumira monga ambiri amanenera.

Komabe, kufotokoza kufunikira kwa chakudya chamtsogolo ndi gawo limodzi la nkhaniyi. "Pazaka makumi angapo zikubwerazi, ulimi uyenera kudyetsedwa kuti udyetse anthu komanso kuti ukhale ndi thanzi labwino," anatero Hunter. Ofufuzawo amanena kuti zizindikiro zotsatila zidzatsimikiziranso kuchuluka kwa mavuto omwe ulimi uyenera kuyang'anizana nawo muzaka makumi angapo zikubwerazi, kusamala kwambiri kafukufuku ndi ndondomeko kuti akwaniritse zotsatira zake.
