Ibimenyetso by’imihindagurikire y’ibihe

Isesengura rikomeye ryerekanye ibimenyetso bigaragara by’imihindagurikire y’ikirere ku rwego rw’isi kuko ubushyuhe bwazamutse bugera kuri 0.8 selisiyusi mu gihe cy’imyaka 150. Ibimenyetso bigaragarira no ku gipimo cy'u Rwanda.

Ibimenyetso by’imihindagurikire y’ibihe mu Rwanda

  • U Rwanda rufite amapfa akomeye, cyane cyane mu burasirazuba no mu majyepfo y'uburasirazuba. Izi mpinduka zijyanye n'ubushyuhe bukabije ku isi. Ingaruka z’imihindagurikire y’ibihe zagaragaye mu Rwanda:
  • Isesengura ry’ibipimo by'ubushyuhe byafatiwe i Kanombe na Kamembe hagati ya 1971 na 2009, byerekana ko ubushyuhe bwiyongereyeho selisiyusi 1,2 mu Rwanda, mu gihe ubushyuhe bwo kwiyongera ku rwego rw'isi ari 0.8 selisiyusi mu gihe cy'imyaka 150
  • U Rwanda rufite ubushyuhe bwiyongera, aho ku manywa; rimwe na rimwe ubushyuhe burenga dogere selisiyusi 30.
  • Mugihe cyimvura (Werurwe, Mata, na Gicurasi) iminsi yizuba yariyongereye
  • Ibihe by'imvura bigenda bigufi kandi bikomeye, cyane cyane mu ntara y'amajyaruguru n'iburengerazuba. Ibyo na byo bigira ingaruka ku musaruro w'ubuhinzi;
  • Rimwe na rimwe, umunsi umwe wimvura urashobora no kugira hafi yimvura igereranijwe kumwezi. Ibi bitera imyuzure, inkangu, nibindi
  • Umubare wimvura yimvura yagabanutse kumwaka. Ikigereranyo kuri sitasiyo ya Kanombe cyerekanye ko hagati ya 1971 na 2009, iminsi y'imvura ku mwaka yagabanutse kuva ku 148 igera ku minsi 124

Ibimenyetso byingenzi by’imihindagurikire y’ibihe ku rwego rw’isi

  • Ubushyuhe bwazamutse bugera kuri dogere 0.8 selisiyusi mugihe cy’imyaka 150
  • Ikigereranyo cy'inyanja ku isi cyazamutse hagati ya 10 na 20cm mu kinyejana gishize
  • Umubare w’ibiza biterwa nimihindagurikire y’ibihe byiyongereyeho ibintu bitanu mu myaka 50
  • Kuva mu mwaka wa 1800, inyanja zahindutse aside hafi 40%, bigira ingaruka ku buzima bwo mu nyanja
