Uburyo Nyungwe itanga amazi mu Rwanda n’ahandi muri Afurika
Isumo ya Ndambarare
Ikigo gishinzwe Ubumenyi bw’Ikirere, Meteo-Rwanda, gihora gitangaza ko imvura igwa ahantu bitewe n’imiterere yaho, iyo hari amashyamba akabasha gutangira imiyaga ifite ubuhehere (amazi), bugahinduka ibicu mbere yo gutanga imvura.

Prof Naramabuye akomeza agira ati “Uretse kohereza amazi mu kirere, ibiti byoherezayo umwuka mwiza ukenerwa n’abantu (n’inyamaswa) bikanagabanya ubushyuhe, byo bigakurayo umwuka wa karubone uteza isi gushyuha, ukaba uva mu bantu, mu byo bakora cyangwa mu nyamaswa.”
Prof Naramabuye avuga ko iyi myuka ya karubone ifite uruhare rukomeye mu kubuza imvura kugwa cyangwa kugwa ari nyinshi cyane mu bice bimwe by’isi(imihindagurikire y’ibihe).
Imiyaga yashyuhijwe n’uwo mwuka wa karubone ikumira isaranganywa ry’imvura ahantu hose, kuko iza igatwara ubuhehere buri mu kirere imvura igahita ibura aho hantu, ariko byagera ahandi hirundanirije ubwo buhehere bwinshi hagatera imyuzure n’inkangu.
Ishyamba rya Nyungwe n’ahandi hari ibiti byinshi, bishobora kuringaniza iyo mihindagurikire y’ikirere kuko imvura ihaboneka, ibyo biti bigakumira isuri, bigafasha ubutaka kwinjiza amazi y’imvura mu mariba y’ikuzimu, ari byo bibyara amasoko y’imigezi.
