Umushakashatsi akaba n’impuguke ku gihingwa cy’imyumbati, Dr Silver Tumwegamire wo mu Kigo mpuzamahanga cy’ubushakashatsi ku buhinzi (IITA), waganiriye na Kigali Today, avuga ko hagikenewe ko imyumvire y’abahinzi ihinduka ku bijyanye n’imbuto, agatanga urugero ku myumbati.

“Uretse n’imbere mu gihugu, abaturage baturiye imipaka bahanahana imbuto z’imyumbati uko bishakiye, ugasanga indwara zirava mu kindi gihugu zikaza mu Rwanda. Ibyo bikunze kugaragara ku baturage begereye Uganda, umwe areba undi uko yarejeje agahita amusaba imbuto agatera”.

Ibyo ngo babikora akenshi batanazi ingaruka bigira ku gihugu ari yo mpamvu ngo hakenewe ubukangurambaga ku bijyanye n’ihererekanya ry’imbuto zitandukanye.

Akomeza avuga ko abahinzi bakwiye guhindura imyumvire, bakikuramo ibyo guhinga imbuto yose babonye kuko itaba yizewe.

Tumwegamire avuga kandi ko IITA ku bufatanye na RAB, barimo gukora ubushakashatsi ku mbuto 15 z’imyumbati ndetse zikaba zaranatangiye kugeragezwa hirya no hino mu gihugu, ngo hakazatoranywamo eshanu nziza kurusha izindi ari zo zizahabwa abaturage guhera mu ntangiriro z’umwaka utaha.

Ubushakashatsi bwerekana ko izo mbuto ngo zizatanga umusaruro wa toni 25 kuri hegitari mu gihe ubu inziza zihari zitanga toni 15 kuri hegitari.
