Nhasi, nyika yakatarisana nedenho yakaoma zvikuru: kunatsiridza kudya kunovaka muviri nokuda kwavose. Kusiyana nemataurirwo anoitwa kushaikwa kwezvokudya zvinovaka muviri munhau dzekuMadokero, idzi hadzisi nyaya mbiri dzakasiyana – kudzikisira varombo uye kudyisa vapfumi. Kupota pasi rose, uyu mutoro wakapetwa kaviri unobatanidzwa nehosha norufu kubva muzvokudya zvakawandisa uye zvishoma. Saka kana tine hanya nekuderedza urombo, tinofanira kufunga nezvekushaya chikafu chinovaka muviri nenzira yakakura, uye kuti nzira dzekurima dzinokanganisa sei.
Mune bepa richangobva kuburitswa, Center for Agriculture and Health Research yakatarisa zvirongwa zana nemakumi mashanu zvekurima kubva pakurima zvirimwa zvakakura zvine mwero wepamusoro wemicronutrients kusvika mukukurudzira kurima gadheni nedzimba.
Vairatidza kuti zvizhinji zvacho zvaisashanda. Somuenzaniso, kugadzirwa kwezvokudya zvinovaka muviri hakurevi kuti zvichadyiwa nevanhu vasina zvokudya zvinovaka muviri. Zviitwa zvakawanda zvekurima zvakanangana nezvigadzirwa zvechikafu.
Semuenzaniso, kupa mhuri mombe kuti dziwedzere mari nekugadzirwa kwemukaka kuitira kusimudzira kudya kunovaka muviri. Asi pane imwe nzira yedambudziko iri, inosanganisira kunzwisisa kuti mitemo yezvekurima neyechikafu iripo sei inokanganisa hutano uye kuti ingasandurwe sei. Chikamu chekudya nekurima cheSangano Romubatanidzwa Wenyika Dzepasi Pose chinosimbisa kukosha kwekutungamirirwa nemusimboti wekuti “musakuvadze” kuitira kudzivirira mhedzisiro yakaipa yemitemo yekurima.
Kunyange mutemo wakabudirira zvikuru unogona kuva nezvinetso zvawo. Somuenzaniso, kusima mari munyika yose mukurima zviyo muzana remakore rapfuura, rava kunzi green revolution, kwakaita kuti mamiriyoni evanhu muAsia ave muurombo uye mukushaya zvokudya zvinovaka muviri. Kana tsvagiridzo yaiiswa pamberi peyakanyanya calorie pane zvirimwa zvine micronutrient zvakapfuma, izvi zvakonzera kuti chikafu chinovaka muviri chiwedzere kudhura nhasi.
Mukupera kwa2013, nerutsigiro rweUK Dhipatimendi reInternational Development uye Bill & Melinda Gates Foundation, Global Panel on Agriculture uye Chikafu Systems yakavambwa “kupa hutungamiriri hunoshanda kune vanoita sarudzo, kunyanya hurumende, mune zvekurima nezvekudya. uye kuisa mari kunyika dzine mari yakaderera nepakati.”
Zvinokurudzira kuona kuwedzera kwekudyidzana kwepasi rose kwekuvandudzwa kwezvokudya zvinovaka muviri.
