Imihindagurikire y’ibihe ni kimwe mu bibazo byihutirwa ku isi, kandi ubuhinzi bw’inyamanswa mu nganda nizo zitera kwihuta. Ubworozi bw'uruganda bugira uruhare runini mu myuka ihumanya ikirere - cyane cyane metani iva mu nka, okiside ya nitrous ivuye mu ifumbire n'ifumbire, na dioxyde de carbone ituruka ku mashyamba yo guhinga ibiryo. Ibyo byuka bihumanya hamwe n’urwego rwose rwo gutwara abantu, bigashyira ubuhinzi bw’inyamanswa hagati y’ibihe byihutirwa by’ikirere.
Kurenga ibyuka bihumanya ikirere, sisitemu ikenera ubutaka, amazi, ningufu byongera umuvuduko wikirere. Amashyamba manini arahanagurwa kugirango akure soya n'ibigori kugirango agaburire amatungo, yangiza imyanda ya karubone kandi arekure karubone yabitswe mu kirere. Mugihe ubwatsi bwagutse kandi urusobe rwibinyabuzima rukaba rwahungabanye, umubumbe w’isi urwanya imihindagurikire y’ikirere uragenda ugabanuka.
Iki cyiciro gishimangira uburyo guhitamo imirire hamwe nuburyo bwo gutanga ibiribwa bigira ingaruka ku kibazo cy’ikirere. Gukemura uruhare rw'ubuhinzi bwo mu ruganda ntabwo ari ukugabanya ibyuka bihumanya ikirere gusa - ahubwo ni ugusubiramo gahunda y'ibiribwa ishyira imbere kuramba, indyo ishingiye ku bimera, hamwe no kuvugurura ibintu. Mu guhangana n’ikirere cy’ubuhinzi bw’inyamaswa, ikiremwamuntu gifite amahirwe yo gukumira ubushyuhe bw’isi, kurinda urusobe rw’ibinyabuzima, no kugira ejo hazaza heza mu bihe bizaza.
Mw'isi ya none, aho ibidukikije bibungabungwa cyane, kugira ubuzima bwibikomoka ku bimera bishobora kugira ingaruka nziza. Muguhitamo kujya mubikomoka ku bimera, ntabwo uhitamo gusa impuhwe zinyamanswa gusa, ahubwo unagira uruhare mukubungabunga umubumbe wacu ibisekuruza bizaza. Ingaruka ku bidukikije ku buhinzi bw’amatungo Ubuhinzi bw’amatungo nimpamvu nyamukuru itera amashyamba, umwanda w’amazi, hamwe n’ibyuka bihumanya ikirere. Umusaruro winyama, amata, nibindi bikomoka ku nyamaswa bisaba ubutaka bwinshi, amazi, nibiryo. Ibi bigira uruhare mu gutema amashyamba kuko amashyamba yatunganijwe kugirango habeho umwanya wo kurisha amatungo cyangwa guhinga imyaka yo kugaburira amatungo. Byongeye kandi, ubuhinzi bwinyamanswa butanga umubare munini w’umwanda. Amazi ava mu myanda y’inyamaswa yanduza imigezi, ibiyaga, inyanja, biganisha ku kwanduza amazi no kurabya kwangiza. Byongeye kandi, gukoresha cyane ifumbire n’imiti yica udukoko mu bihingwa by’amatungo bikomeza kugira uruhare…
