Kugira inshuti magara ya hafi benshi bita 'Besto' cyangwa 'Bestie' mu ndimi z'amahanga, ntabwo biba mu bantu gusa ahubwo ngo no mu matungo bibamo cyane cyane mu nka nk'uko ubushakashatsi bushya bwabigaragaje.
Ubushakashatsi buherutse gukorwa muri Kaminuza ya Northampton mu Bwongereza, bwerekanye umubano umeze nk'uw'abantu hagati y'Inka. Bwerekanye ko Inka zifite ubucuti bukomeye hagati yazo kugera aho usanga inka ifite inshuti magara bigendana.
Ubushakashatsi bwatewe ahanini n’impaka zabereye mu Bwongereza ku byiswe amata y’amata, ayo afite inka ziri hagati ya 3000-8000. Benshi mu nganda z’amata bashyigikira amata ya 'mega' kuko babonwa nk'igisubizo cyo kuzamura irushanwa (rikunze kuba code yo gutanga amata ku biciro biri hasi kurenza abo bahanganye).
Ubu bushakashatsi bwibanze ku nka zo mu rugo n’ubworozi byombi bikunze kuboneka mu matsinda mato byagaragaje ko hariho imibanire myiza y’imibereho. Urugero, inka zororerwa hamwe zigumana ubumwe bukomeye ubuzima bwose ugereranije n'inka zatangijwe cyangwa zinjiye mu matsinda yabo mu gihe cya nyuma.
Umushakashatsi Krista Marie McLennan yiyemeje kureba ingingo yakorewe ubushakashatsi ku kuntu ubusabane bufite akamaro ku mibereho y’inka mu bucuruzi bunini bw’amata.
Amaze gushyira ahagaragara ibyo yiboneye mu bworozi bw'inka, McLennan yahisemo kubanza kumenya inka nziza kurusha izindi. Ibihumbi byinshi byakurikiranwe byanditswe mu gihe inyamaswa zirisha, ziruhuka kandi ziragaburirwa.
Yashakaga izindi nka zamaraga igihe kinini hafi yazo. Uyu mushakashatsi yabonye uburyo busobanutse bw'imibanire ko hejuru ya 50% inka zikunda kumarana umwanya munini n'izindi nka.
Ubukurikira, umushakashatsi yitegereje ingaruka zifatika cyangwa imyitwarire yo gutandukanya amashyo. Bafashe inka cumi n'imwe zigizwe n'esheshatu zifitanye isano.
Inka zitandukanijwe n'ubushyo: (1) muminota 30 hamwe na mugenzi wabo bakunda, na (2) mu minota 30 hamwe n'inka idakunzwe. Ibyavuye mu bushakashatsi byagaragaje ko inka zitandukanijwe n’inshuti zazo zerekanaga ko umutima udatuje cyane kuruta igihe bari kumwe nazo.
Inka nazo zifite ibibazo
Mu rwego rwo gushaka amata agezweho, inka zikunze guhura no gutandukana n'ubushyo bwazo. Hashobora kubaho igihe gito cyo gutandukana, nko mu gihe cyo kugenzura buri gihe abaganga, cyangwa kwigunga nyuma yo gukamwa cyangwa igihe.
Gutandukana bishobora kandi kuba igihe kirekire. Mu bucuruzi ibi birashoboka cyane cyane mu buryo bw'ubworozi bw'ibanze buzwi nka 'regrouping'. Hano inka z'amata zashyizwe mu byiciro ukurikije icyiciro cy'umusaruro zitanga.
Urugero inka zonsa zishyizwe hamwe, kandi zitandukanijwe n'izitari konsa. Hariho ibimenyetso byinshi byerekana ko gutandukana kw'amatungo magufi by'igihe kirekire bishobora gutera imihangayiko, bigaragazwa no kwiyongera kw'ijwi, kurwana no kuzamuka kwitera ry'imitima yazo.
Guterana ni isoko yo hejuru cyane yo guhangayika. Inka ziteranyirizwa hamwe hagati y'inshuro 4 na 12 mu mwaka. Buri mpinduka isobanura kugendagenda mu byiciro by'imibereho y'itsinda rishya, bigatuma bigora bidasanzwe inka gushyiraho imibanire mishya. Nk'uko byasobanuwe na McLennan:
“Guhuriza hamwe inka akenshi bifitanye isano no kwiyongera k'ubugizi bwa nabi mu gihe abantu bagerageza kwerekana umwanya wabo mu nzego z'ubuyobozi. Inyamaswa zigomba guhatanira kubona umutungo w'ingenzi, nk'ibiryo, kugira ngo ziruhuke, mu matsinda akunze kuganzwa n'abantu. Guhangayikishwa n’izo mpinduka mu matsinda bishobora kugira ingaruka zikomeye ku buzima n’imibereho myiza y’inka zitanga amata… ”
Ingaruka mbi zo gusubiranamo zirakaze cyane mu minsi yabo ya mbere yo kumenyekanisha, ariko bizakomeza kugeza igihe urwego rw'imibereho rwimuriwe. Ibi birashobora gufata ahantu hose hagati yibyumweru bibiri cyangwa bitatu.
Inka zigira aba 'Besto'
Abashakashatsi bafashe inka hamwe n’inshuti zazo bakunze kuba barikumwe hanyuma barazitandukanya ibyumweru bibiri, mbere yo kongera kuzihuza. Kimwe n'ingaruka zo gutandukana mu gihe gito, inka zerekanye impinduka mbi mu myitwarire yazo, ubuzima, imibereho myiza n'umusaruro. Ariko iyo bongeye guhura na ngenzi yazo bakundana (bamarana igihe barisha) zagaragaje ibimenyetso byinshi by'ubusabane. Ubucuti bwazo bwakomeje neza.
Ati: “Imibanire myiza yari yaramenyekanye mbere yasaga nk'aho yacitse nyuma yo gutandukana igihe kirekire. Byongeye kandi, nyuma yo guhura inka ntizasaga nk'aho zongeye kugirana umubano wabo… Ibi byavugaga ko inka zitasabana nyuma y'igihe cyo gutandukana ugereranije na mbere yo gutandukana ”.
Imibereho n'amarangamutima y'inka ntabwo ari kintu dukunda gutekereza. Inka zikunze gutekerezwa nk'inyamaswa zidafite ubwenge, hamwe n'agaciro kazo muri sosiyete yacu nta kindi kirenze ko zitanga amata, inyama n'ifumbire.
Ariko ubushakashatsi bw'ibanze bwakozwe na Krista Marie McLennan bwiyongera ku bimenyetso bifatika byerekana ko nk'abantu, ubusabane hagati y'inka ari ikintu gikomeye.
