Ibiciro vy’imipira y’imipira y’amazi vyarateye imbere muri uyu mwaka, ariko abahinguzi bazogwana n’iyindi myaka cumi n’ibiciro bito, inganda z’imbere mu nganda zivuga.
Naho 16% vy’ibiciro vy’imipira y’umupira w’amaguru kw’isi yose gushika ubu muri uyu mwaka, ikipimo kiracari kure y’ukuri kw’isoko ry’idubu, nk’uko bivugwa n’abaje mw’isoko{1}}
Kuva muri Werurwe 2009 gushika muri Ruhuhuma 2011, ibiciro vy’imipira vyaradutse, aho vyaduze nk’ibice 240% .Abaguzi na bo nyene bariko baragwira cane mu kiringo c’imyaka ibiri y’ibiciro vy’ibiciro, kandi ubu igitero c’ugutanga ni ikibazo kizoba kigoye gukuraho mu gihe gito uko ibiti vy’imipira bigenda biva mu nzira y’iterambere gushika ku nzira y’ugutera imbuto{5}} Naho ibiciro vy’ibinyabiziga vyadutse muri uyu mwaka, ni vyo n'ubu nyene 70 kw'ijana ku bice vyabo vy'imbere mu mwaka wa 2011 .
Guhingura ibiti kw’isi yose bizobandanya gusumba ivyifuzo vy’amapine gushika 2027-2028, kandi ibihugu vy’abahinguzi bizoguma Mired mu bici- ro bito mu yindi myaka cumi, nk’uko bivugwa na David Shaw, umuyobozi mukuru w’ubushakashatsi bwa Tire Industry UK, imaze imyaka 30 ikurikirana Industry, nk’uko bivugwa n’ibinyabiziga vy’amapine.
Iyo abahingura imipira bakoresheje uruziga rwa 10- mu myaka ya mbere kugira ngo bashireho ivyifuzo vyo muri kazoza no kumenya uburebure bivanye n’ivyo, nta ngaruka mbi n’ibiciro vyoca bigumaho, nk’uko Shaw .Avuga ko intwaro ziri mu bihugu bihingura imipira zikwiye kwiyubara cane kugira ngo zishike ku rugero hagati y’ugutanga n’ugusaba muri kazoza.
Igiti c’umukara cari caraciwe inyuma y’aho 5-7 imyaka, igihe c’amashyamba bwinshi cari 10-15 imyaka, kandi igihe co gusesa no gusanura cari 25-35 imyaka . Imyambaro idasanzwe, iyo hejuru ni ibicuruzwa vy’uburimyi, ariko kandi ifise ibintu bikomeye vy’ivy’ubutunzi.
Thailand is the world's largest producer, accounting for 36 per cent of global output, according to previous data from the hongyuan futures research institute.China accounts for nearly 40 per cent of global natural rubber consumption and more than 70 per cent of that is used in tyre manufacturing, but the growth rate of Chinese tyre production has slowed from 20 per cent in 2010 to 5.4 per cent in 2017.
Kubera ko hariho ukudahuza hagati y’ugutanga n’ugusaba, biragoye ko imipira isanzwe igabanya umusaruro ku rugero rumwe n’amavuta y’agaciro.
Zhu ziyue y’ubushakashatsi bw’imbere mu gihe c’imbere mu gihe c’iteraniro ryerekanye kandi ko ahantu h’ugutera hagoye gusohoka ningoga mw’isoko ry’idubu kandi akarere k’ugutera kenshi gakoreshwa cane mw’isoko ry’ibimasa, ivyo bikaba bituma bigorana gukuraho umukazo w’ibibumbano vy’imipira.Na we nyene yavuze ko:
Mbere na mbere, imipira y’amazi ifise uruziga rurerure rw’ukukura n’ingendo ndende y’ugukata imipira, rero umusaruro n’ibintu ntibishobora guhindurwa ku gihe kubera ko hariho uruziga rurerure. Mu isoko ry’ibimasa, gutera imbuto zikunda kwirukira imbere, mu gihe mw’isoko ry’idubu rigoye gusohoka ningoga.
Ica kabiri, 90% vy’ibibanza vyo guhingura imipira vyo kw’isi biri mu bumanuko bushira ubuseruko bwa Aziya, bikoreshwa mu buryo bw’amatongo matomato kandi kigatanga mu buryo butashwiraho.
Ubwa nyuma, guca imipira ni inkomoko y’ubutunzi abarimyi b’imipira bashingiye ku buzima bwabo, kandi igiciro ca nyuma co gusanasana ubutaka bw’imipira ni hasi. Naho hariho ikintu co gusubirira gutera canke guhitamwo ibindi bikorwa, nta bundi buryo bwo gutanga amahera adahinduka ku barimyi b’imipira, rero ntibazohitamwo guheba guca canke guca .
