Inyamaswa

Iki cyiciro gisuzuma uburyo inyamaswa-ibyiyumvo, ibiremwa bitekereza-bigira ingaruka kuri sisitemu twubaka n'imyizerere dushyigikira. Hirya no hino mu nganda n’umuco, inyamaswa ntizifatwa nkabantu ku giti cyabo, ahubwo zifatwa nkibice by’umusaruro, imyidagaduro, cyangwa ubushakashatsi. Ubuzima bwabo bwamarangamutima bwirengagijwe, amajwi yabo araceceka. Binyuze muri iki gice, dutangiye gusobanura ibyo bitekerezo no kuvumbura inyamaswa nkubuzima bwumutima: bushobora gukunda, kubabara, amatsiko, no guhuza. Nugusubiramo abo twize kutabona.
Ibyiciro biri muri iki gice bitanga ibyiciro byinshi byerekana uburyo ibibi bisanzwe kandi bishyirwa mubikorwa. Inyamanswa zinyamaswa ziraduhatira kumenya ubuzima bwimbere bwinyamaswa na siyanse ibishyigikira. Imibereho myiza y’inyamaswa n’uburenganzira bibaza amahame mbwirizamuco kandi bikerekana inzira zo kuvugurura no kwibohora. Ubuhinzi bwuruganda bugaragaza bumwe muburyo bukabije bwo gukoresha inyamaswa-aho gukora neza birenze impuhwe. Mu bibazo, dukurikirana uburyo bwinshi bwubugome bwashyizwe mubikorwa byabantu - kuva ku kato no ku munyururu kugeza ku bizamini bya laboratoire no mu ibagiro - byerekana uburyo ako karengane gakabije.
Nyamara intego y'iki gice ntabwo ari ugushyira ahagaragara ubugome gusa, ahubwo ni ugukingura inzira igana impuhwe, inshingano, n'impinduka. Iyo twemeye kumva inyamaswa hamwe na sisitemu zibangiza, natwe tubona imbaraga zo guhitamo ukundi. Ni ubutumire bwo guhindura ibitekerezo byacu - kuva kuganza kugera kububaha, kuva mubi kugana mubwumvikane.

Ubuhinzi bwuruganda, uburyo bwateye imbere cyane kandi bukomeye bwo korora amatungo kubyara umusaruro, byabaye ikibazo cyibidukikije. Inzira yinyamanswa itanga ibiryo ntabwo itera gusa ibibazo byimyitwarire yimibereho yinyamaswa ahubwo inagira ingaruka mbi kwisi. Hano hari ibintu 11 by'ingenzi byerekeranye n'imirima y'uruganda n'ingaruka zabyo ku bidukikije: 1- Imirima minini y’ibyuka bihumanya ikirere ni kimwe mu bigira uruhare runini mu kwangiza imyuka ihumanya ikirere ku isi, ikarekura metani na oxyde ya nitrous mu kirere. Iyi myuka irakomeye cyane kuruta dioxyde de carbone mu ruhare rwayo mu bushyuhe bw’isi, metani ikaba ifite inshuro zigera kuri 28 mu gufata ubushyuhe mu gihe cy’imyaka 100, na okiside ya nitrous ikubye inshuro 298. Inkomoko yambere y’ibyuka bya metani mu buhinzi bw’uruganda ikomoka ku nyamaswa z’amatungo, nk'inka, intama, n'ihene, zitanga metani nyinshi mu gihe cyo gusya…

Ubworozi bw'uruganda, buzwi kandi nk'ubuhinzi mu nganda, ni ubuhinzi bugezweho bukubiyemo umusaruro mwinshi w'amatungo, inkoko, n'amafi ahantu hafunzwe. Ubu buryo bwo guhinga bwarushijeho kwiyongera mu myaka mike ishize ishize kubera ubushobozi bwabwo bwo gukora ibikomoka ku nyamaswa nyinshi ku giciro gito. Nyamara, iyi mikorere ije ku kiguzi kinini haba ku mibereho y’inyamaswa ndetse n’ibidukikije. Ingaruka zo guhinga uruganda ku nyamaswa no ku isi ni ikibazo kitoroshye kandi gifite impande nyinshi cyakuruye impaka n’impaka mu myaka yashize. Muri iki kiganiro, tuzareba uburyo butandukanye ubuhinzi bw’uruganda bwagize ku nyamaswa ndetse no ku bidukikije, n'ingaruka bigira ku buzima bwacu no kuramba kwisi. Kuva ku gufata nabi ubugome n'ubumuntu kugeza ku ngaruka mbi ku butaka, amazi, n'umwuka, ni ngombwa kuri…

Imiryango ishinzwe imibereho myiza y’inyamanswa iri ku isonga mu guhangana n’ubugome bw’inyamaswa, ikemura ibibazo byo kutita ku ihohoterwa, guhohoterwa, no gukoreshwa n’ubwitange budacogora. Mu gutabara no gusubiza mu buzima busanzwe inyamaswa zafashwe nabi, guharanira ko amategeko arengera amategeko, no kwigisha abaturage kwita ku mpuhwe, iyi miryango igira uruhare runini mu kurema isi itekanye ku binyabuzima byose. Imbaraga zabo zifatanije ninzego zubahiriza amategeko no kwiyemeza gukangurira abaturage ntibifasha gusa gukumira ubugome ahubwo binashishikarizwa gutunga amatungo ashinzwe no guhindura imibereho. Iyi ngingo iragaragaza akazi kabo gakomeye mu kurwanya ihohoterwa ry’inyamaswa mu gihe baharanira uburenganzira n’icyubahiro by’inyamaswa ahantu hose

Ingurube, izwiho ubwenge nuburebure bwamarangamutima, yihanganira imibabaro idashoboka muri gahunda yo guhinga uruganda. Kuva mubikorwa byo gupakira urugomo kugeza kubintu bitwara abantu nuburyo bwo kubaga abantu, ubuzima bwabo bugufi burangwa nubugome budashira. Iyi ngingo iragaragaza ukuri gukabije guhura n’izi nyamaswa zumva, zigaragaza ko byihutirwa impinduka mu nganda zishyira imbere inyungu kuruta imibereho myiza

Inkoko zirokoka ibintu biteye ubwoba byamazu ya broiler cyangwa akazu ka batiri akenshi bakorerwa ubugome bukabije kuko bajyanwa mubagiro. Izi nkoko, zororerwa gukura vuba kugirango zitange inyama, zihanganira ubuzima bwo kwifungisha bikabije nububabare bwumubiri. Nyuma yo kwihanganira ibintu byinshi, byanduye mumasuka, urugendo rwabo kubagiro ntakintu kibi kirimo. Buri mwaka, amamiriyoni yinkoko arwara amababa namaguru bivuye kumikorere mibi bahura nabyo mugihe cyo gutwara. Izi nyoni zoroshye akenshi zijugunywa hirya no hino nabi, bigatera imvune numubabaro. Kenshi na kenshi, kuva amaraso kugeza apfuye, ntibashobora kurokoka ihahamuka ryo guhurira mu bisanduku byuzuye abantu. Urugendo rugana ibagiro, rushobora kurambura ibirometero amagana, rwiyongera ku mibabaro. Inkoko zapakiwe cyane mu kato nta mwanya wo kwimuka, kandi nta biryo cyangwa amazi bahabwa…

Amamiriyoni y'inka yihanganira imibabaro myinshi mu nganda z’inyama n’amata, ibibazo byabo ahanini bikaba bitagaragara mu bantu. Kuva aho abantu buzuye, buzuye amakamyo atwara abantu kugeza ibihe byanyuma biteye ubwoba mu ibagiro, izo nyamaswa zumva zihura n’uburangare n’ubugome bidasubirwaho. Yanze ibikenerwa byibanze nkibiryo, amazi, nuburuhukiro mugihe cyurugendo rurerure mugihe cyikirere gikabije, benshi bahitanwa numunaniro cyangwa ibikomere mbere yuko bagera aho berekeza. Mu ibagiro, ibikorwa biterwa ninyungu akenshi bituma inyamaswa ziguma zifite ubwenge mugihe cyubugome. Iyi ngingo iragaragaza ihohoterwa rishingiye ku nganda ryashinze imizi muri izo nganda mu gihe riharanira ko abantu barushaho kumenyekana no guhindura amahitamo ashingiye ku bimera nk'inzira y'impuhwe zitera imbere

Buri mwaka, amamiriyoni y’inyamaswa zo mu murima yihanganira ingendo zitoroshye mu bucuruzi bw’amatungo ku isi, yihishe mu ruhame nyamara yuzuye imibabaro idashoboka. Yuzuye mu gikamyo cyuzuye abantu, amato, cyangwa indege, ibyo biremwa bifite imyumvire ihura n’ibihe bibi - ikirere gikabije, umwuma, umunaniro - byose bidafite ibiryo bihagije cyangwa ikiruhuko. Kuva ku nka n'ingurube kugeza ku nkoko n'inkwavu, nta bwoko bwarokotse ubugome bwo gutwara inyamaswa nzima. Iyi myitozo ntabwo itera impungenge z’imyitwarire n’imibereho gusa ahubwo inagaragaza kunanirwa muri gahunda mu kubahiriza amahame y’ubuvuzi bwa kimuntu. Mugihe abaguzi barushijeho kumenya ubwo bugome bwihishe, ihamagarwa ryimpinduka riragenda ryiyongera - bisaba kubazwa no kugirirwa impuhwe mu nganda ziterwa ninyungu bitwaje ubuzima bwinyamaswa

Nubwo guhiga byigeze kuba igice cyingenzi mubuzima bwabantu, cyane cyane mumyaka 100.000 ishize mugihe abantu ba mbere bashingiraga guhiga ibiryo, uruhare rwarwo muri iki gihe ruratandukanye cyane. Muri societe ya none, guhiga byahindutse cyane cyane ibikorwa byo kwidagadura bikabije aho gukenera ibibatunga. Kubenshi mubahiga, ntabwo bikiri uburyo bwo kubaho ahubwo ni uburyo bwo kwidagadura bukunze kwangiza inyamaswa bitari ngombwa. Impamvu zitera guhiga muri iki gihe zisanzwe ziterwa no kwinezeza kugiti cyawe, gushaka ibikombe, cyangwa gushaka kwitabira imigenzo ya kera, aho gukenera ibiryo. Mubyukuri, guhiga byagize ingaruka mbi ku baturage b’inyamaswa ku isi. Yagize uruhare runini mu kuzimangana kw'ibinyabuzima bitandukanye, hamwe n'ingero zigaragara zirimo ingwe ya Tasimani na auk nini, abaturage bayo bakaba bararimbuwe n'ubukorikori. Uku kuzimangana guteye kwibutsa kwibutsa…

Inyamaswa zo mu muhanda zishobora kureshya abagenzi n'amasezerano yo guhura hafi n’inyamaswa zishimwa, ariko inyuma ya façade hari ukuri gukabije. Ibi bintu nyaburanga bidakurikiranwa bikoresha inyamanswa mu nyungu, zifunga inyamaswa ahantu hafunganye, hatarimo ingumba zidashobora guhaza ibyo bakeneye by'ibanze. Bapfunditswe nk'imbaraga zo kwigisha cyangwa kubungabunga ibidukikije, bakomeza ubugome binyuze mu bworozi bw'agahato, kubitaho, no kubeshya. Kuva ku nyamaswa z’abana zitandukanijwe cyane na ba nyina kugeza ku bantu bakuru bihanganira ubuzima bwabo bwose, ibyo bigo byerekana ko hakenewe byihutirwa ubukerarugendo bw’imyitwarire bushyira imbere imibereho y’inyamaswa kuruta imyidagaduro.
