Ubwubatsi bwiza bwububiko bwamashyamba nibyatsi (Ubukungu burimunsi)

Ubushinwa bwa karuboni n’ingamba zo kutabogama kwa karubone bihura ningorane n’ibibazo nko kugabanya ibyuka bihumanya ikirere, imirimo ihindagurika cyane, hamwe n’amadirishya akomeye.Nigute iterambere ryubu rya "dual carbone"?Nigute amashyamba ashobora gutanga umusanzu munini kugirango ugere ku “karuboni ebyiri”?Mu nama mpuzamahanga iherutse gukorwa ku mashyamba n’ibyatsi Carbon Sink Innovation, abanyamakuru babajije impuguke zibishinzwe.

Ibintu nyamukuru bigira ingaruka ku kugera ku ntego z’ubushinwa “bubiri bwa karubone” ni inganda zikomeye, inganda zishingiye ku makara, n’ubushobozi buke.Byongeye kandi, Ubushinwa bwabitse imyaka igera kuri 30 kugira ngo bugere ku kutabogama kwa karubone, bivuze ko hagomba gushyirwaho ingufu nyinshi mu guteza imbere ubukungu n’imibereho myiza y’abaturage ndetse n’imihindagurikire y’icyatsi kibisi na karuboni nkeya.

Impuguke zitabiriye iyi nama zavuze ko gukoresha ingufu za karubone no kutabogama kwa karubone mu guteza imbere ikoranabuhanga mu Bushinwa no guhindura iterambere ari ikintu cyihariye gisabwa kugira ngo ubukungu bw’imibereho myiza ndetse n’imibereho myiza, byanze bikunze bisabwa kurengera ibidukikije mu rwego rwo hejuru ibidukikije, ndetse n’amahirwe y’amateka kugabanya icyuho cyiterambere nibihugu bikomeye byateye imbere.Nk’igihugu kinini mu bihugu bikiri mu nzira y'amajyambere, gushyira mu bikorwa ingamba z’ubushinwa “karuboni ebyiri” bizagira uruhare runini mu kurinda igihugu cy’isi.

Ati: “Duhereye ku gihugu ndetse no mu mahanga, dukeneye gukomeza kwibanda ku kugera ku mpinga ya karubone no kutabogama kwa karubone.”Du Xiangwan, umujyanama wa Komite y’igihugu y’impuguke z’imihindagurikire y’ibihe akaba n’umuhanga mu banyamuryango ba CAE, yavuze ko gushyira mu bikorwa ingamba za “karuboni ebyiri” ari gahunda.Mu kwihutisha iterambere ryikoranabuhanga no guhinduka, turashobora kugera kumurongo mwiza wa karubone no kutabogama kwa karubone kuri gahunda.

Ati: “Muri 2020, Ubushinwa bwagaragaje ko amashyamba n'ibyatsi bya karuboni bizaba ari toni miliyari 88.586.Mu 2021, Ubushinwa buri mwaka amashyamba n’ibyatsi bya karuboni bizarenga toni miliyari 1,2, biza ku mwanya wa mbere ku isi, ”ibi bikaba byavuzwe na Yin Weilun, umwarimu w’umunyamuryango wa CAE.Biravugwa ko ku isi hari inzira ebyiri nyamukuru zo kwinjiza dioxyde de carbone ku isi, imwe ni amashyamba yo ku isi, indi ni ibinyabuzima byo mu nyanja.Umubare munini wa algae mu nyanja ukurura karuboni ya dioxyde, hanyuma igahinduka ibishishwa na karubone kugirango ibike mu kuzenguruka ibintu no guhinduranya ingufu.Amashyamba ku butaka arashobora gufata karubone igihe kirekire.Ubushakashatsi bwa siyansi bwerekana ko kuri metero kibe yo gukura, ibiti bishobora gukuramo impuzandengo ya toni 1.83 ya dioxyde de carbone.

Amashyamba afite imikorere ikomeye yo kubika karubone, kandi ibiti ubwabyo, byaba selile cyangwa lignine, bigizwe no kwegeranya dioxyde de carbone.Igiti cyose nigicuruzwa cya karuboni ya dioxyde.Ibiti birashobora kubikwa imyaka amagana, ibihumbi, cyangwa imyaka miriyari.Amakara yacukuwe muri iki gihe yahinduwe kuva miriyari yimyaka yo gutegura amashyamba kandi ni karuboni nyayo.Muri iki gihe, amashyamba y’Ubushinwa ntabwo yibanda gusa ku gukora ibiti, ahubwo yibanda no gutanga ibicuruzwa by’ibidukikije, kwinjiza dioxyde de carbone, kurekura ogisijeni, kubungabunga amasoko y’amazi, kubungabunga ubutaka n’amazi, no kweza ikirere.
