Amakuru - Kuki ibirundo by'ibyuma bikoreshwa cyane?

Nka mijyi kwisi yose irushanwa kuzamura ibikorwa remezo bishaje no kubaka imijyi mishya,ibirundo by'icyumabyagaragaye nkumukino uhindura igisubizo-hamwe nubwihuta bwihuse bwo kwishyiriraho bihinduka umushoferi wingenzi wo kurera, gufasha abashoramari kugabanya igihe cyumushinga mugihe gahunda yo kubaka imijyi itoroshye.

Inganda ziva mu ishyirahamwe ry’ubwubatsi bw’isi (GSCA) zerekana 22% umwaka ushize kwiyongeraurupapuroimikoreshereze yimishinga yo mumijyi muri 2024, kwagura metero, kwagura inkombe zamazi, hamwe nubucukuzi bwimbitse kubikorwa fatizo ndende. Bitandukanye na beto gakondo igumana ibyumweru bisaba ibyumweru byo gukiza,impapuro zigezweho-Ibyakozwe mbere kugirango byuzuze ibipimo byihariye byumushinga - birashobora gutwarwa mubutaka ku kigero cya metero 15 kugeza kuri 20 kumurongo, kugabanya igihe cyo kubaka aho 30% ugereranije.

Maria Hernandez, injeniyeri mukuru w’ibikorwa remezo mu kigo cy’ubwubatsi cya EuroBuild gifite icyicaro i Madrid yagize ati: "Kubaka imijyi ntibitegereza - gutinda bisobanura amafaranga menshi ndetse no guhungabanya umutekano ku baturage." Ati: "Ku mushinga uherutse kwagura metero muri Barcelona, duhinduranyaAmashanyarazi ashyushyekumuyoboro ugumana inkuta zogosha iminsi 12 yicyiciro cyo gucukura. Ibyo ni ingenzi cyane iyo ukorera mu duce twinshi kandi utagerwaho. ”

Ubujurire bwaurupapuroirenze umuvuduko. Imyenda yabo irwanya ruswa (nka hot-dip galvanisation cyangwa polymer ivura) ituma iramba mugukoresha ibikorwa remezo byigihe kirekire, mugihe igishushanyo mbonera cyabo gishobora gukuraho no kongera gukoresha mumishinga iri imbere - bihuza nintego zo gukomeza imijyi kwisi yose. Muri Singapuru yo kuzamura amazi y’amazi ya Marina Bay, urugero, ibirundo byashyizweho mu 2023 kugirango bigarure ubutaka bwasubiwemo bizasubizwa mu mushinga wo kurengera inkombe uri hafi mu 2025, bigabanye imyanda y’ibikoresho 40%.

Abategura umujyi nabo barimo kubona inyungu zumuhanda no kugera kumugaragaro. I Toronto, umushinga wo kwagura umuhanda mu gihembwe gishize wakoresheje ibirundo byo kubaka inkuta zagumanye by'agateganyo ku kazi. Umuvugizi w'ishami rishinzwe gutwara abantu n'ibintu muri Toronto, James Liu yagize ati: "Kubera ko kwishyiriraho byarangiye mu ijoro rimwe gusa, twirinze gufunga umuhanda wose mu masaha yo hejuru - ikintu kikaba kidashoboka n'inkuta za beto."

Ababikora baritabira ibisabwa byiyongera muguhanga udushya. Mu ntangiriro z'uku kwezi, uruganda rukora ibyuma rwo mu Buholandi ArcelorMittal rwashyize ahagaragara ubwoko bushya bw’urupapuro rworoshye rwerekana ibirundo bigumana imbaraga nyinshi ariko bikaba byoroshye 15% gutwara no gushiraho, byibanda ku mishinga minini yo mu mijyi yo hagati aho imashini ziremereye ziba nke.

Impuguke mu nganda ziteganya ko iyi gahunda izihuta mu 2025, biteganijwe ko ifumbire y’ibirundo iziyongera ku gipimo cya 18% mu gihe imijyi yo muri Aziya na Afurika izamura ishoramari ry’ibikorwa remezo. Ushinzwe gusesengura ibikorwa remezo bya GSCA, Raj Patel yagize ati: "Ibisagara ntibidindiza, kandi abashoramari bakeneye ibisubizo bingana umuvuduko, umutekano, ndetse no kuramba." “Ibirundo by'impapuro bigenzura utwo dusanduku twose - kandi uruhare rwabo mu gushiraho inyubako nziza zo mu mijyi ruzagenda rwiyongera.”
