Mu binyejana byinshi, imashini zitora icyayi byabaye akamenyero mu nganda zicyayi gutora icyayi ukurikije igishushanyo “kimwe, amababi abiri”. Yaba yatowe neza cyangwa idahindura muburyo bwo kwerekana uburyohe, igikombe cyicyayi gishyiraho urufatiro mugihe cyatoranijwe.

Kugeza ubu, uruganda rwicyayi ruhura nibibazo byinshi bigoye. Kimwe mu bintu byamamaye cyane mu buhinzi ku isi ni uko ubucuruzi bushishikariza ababikora kwagura umusaruro, bigatuma ibicuruzwa bitangwa cyane, ibiciro biri hasi n’amafaranga yinjira. Byihuta-imyaka 60, kandi aba batanga icyayi cyibicuruzwa bazahura nibindi bitandukanye: ibiciro byumusaruro byazamutse kubera igiciro kinini cyo gutoragura intoki, ariko ibiciro byakomeje kwiheba. Kugirango ugume mu bucuruzi, abatunganya icyayi babwirijwe guhindura byinshi kubakozi bakegutora icyayi.

Muri Sri Lanka, impuzandengo y'abatora kuri hegitariimashini yubusitani bwicyayiyagabanutse kuva ku kigereranyo cya kabiri igera kuri imwe gusa mu myaka icumi ishize, kuko byoroshye gukoresha imashini zihinga icyayi mu gutoranya amababi mabi. Birumvikana ko abakoresha icyayi aribo bahura niyi mpinduka. Nubwo batitaye ku kuzamuka gukabije kw'ibiciro byo kugurisha, uburyohe bwaicyayibanywa bigenda bigabanuka buhoro buhoro. Nubwo ibipimo byo gutoranya biri hasi hamwe nabatora icyayi bake, biracyagoye kubona akazi keza ko gutoranya - umusaruro mwinshi utanga umusaruro muke nicyitegererezo cyambere cyo gutwara ingwe, kubwibyo byanze bikunze abatunganya icyayi bahindukira gutoragura imashini.
