Kubera ububabare bwo guca ibice vyoroshe, umunuko w’amafi uremereye be n’amavuta menshi mu gutunganya inyama z’ikiyaga zisanzwe, ishirahamwe ryacu ryatanguje ubuhinga bugeneweumuriro w'ubusaumuti inyuma y’ubushakashatsi bw’ubuhinga. Igikoresho co gutunganya ivyokurya vyo mu kiyaga c’umwuga carashizwe ku mugaragaro mu guteza imbere isoko.
Iyi nkoko y’umuyaga itunganya umuvuduko wo guteka mu mwuka n’ubushuhe buke-bushuhe bivanye n’ibiranga ibikoresho vya mbere vy’ibifungurwa vyo mu kiyaga nk’ibitoke, ifi n’ibitoke vy’umukara. Ishobora gukuraho neza umunuko w’amafi w’ivyo mu kiyaga mu gihe ifunga uburyohe bushasha, kandi igakingira ibikoresho bitagira agaciro guca ibice mu gihe co kubitunganya. Ivyo bifungurwa vyo mu kiyaga bitunganijwe birafise amavuta make, biraryoha cane kandi biraboneka neza.
Muri iki gihe, iyo nkoko y’ibifungurwa vyo mu kiyaga-ikoreshwa neza mu bigo vyinshi bitunganya ibifungurwa vyo ku nkengera y’ikiyaga mu gihugu no mu mahanga. Turashobora gutanga ibikorwa vy’uguhindura ivyuma vy’amazi bivanye n’ibikoresho bitandukanye vy’ibifungurwa vyo mu kiyaga be n’ubushobozi bwo gukora ivyo abakiriya bakeneye.
