Kuri mwarimu Adolphe ukuriye agashami ka environmental health science muri kaminuza y’u Rwanda, asanga hari ibyakorwa mu kugabanya kwandura kw’ikirere cyo mu mijyi n’ubwo kuri we abona hari ingamba zakumvikana nk’izigoye gushyirwa mu bikorwa.
Akomeza avuga ko reta yagabanya imodoka z’abantu ku giti cyabo (private transport) hakavugururwa uburyo bwo gutwara abantu muri rusange (public transport), akongeraho ko gusuzuma ibinyabiziga (technical control) bigomba gushyirwamo imbaraga bityo imodoka zatangiye guhumanya ikirere zikajya zikurwa mu muhanda hakiyongeraho gukumira izanwa ry’imodoka zakozwe mbere ya 2000 kuko zihumanya ikirere cyane.
Mwalimu Adolph asanga habaye kongera ibiti n’ibyanya biharirwa ibimera mu mijyi byagira umumaro mu kugabanya kwandura kw’ikirere guturutse ku myotsi kuko ibyo biti bikenera umwuka wanduye mu gihe byo bisohora umwuka abantu bakenera.
