Utshintsho lwemozulu lunokuchaphazela izilwanyana kunye nezityalo ezininzi ngeendlela esingakwaziyo nokucinga ngazo. Ukususela ekuqhekekeni kwindawo yabo yokuhlala ukuya kutshintsho kwi-phenology kunye nemijikelezo yabo, Utshintsho lwemozulu lubangela utshintsho oluninzi (ezinye zazo azinakuphikiswa) kwiindidi ezininzi zehlabathi.
Kule meko siza kuthetha ngendoda ye iflegi yokubambisa. Intaka enebala elimhlophe entlokweni yayo ibaluleke kakhulu ekuzaleni nasekukhwelweni kwayo. Ukutshintsha kwemozulu kuyichaphazela kangakanani le ntaka ixabisekileyo?
Isicwangciso esiliqili seFlycatcher
Indoda yendoda ebunjiweyo iflycatcher inayo indawo emhlophe entloko kwaye ibaluleke kakhulu kukhangelo lwakho lomntu obhinqileyo. Eyona ndawo inkulu entlokweni, kokukhona inomdla ngakumbi kwabasetyhini kwaye kokukhona beya kuyidlulisela kwimfuza yabo. Oku kuye kwenzeka ngonaphakade. Nangona kunjalo, kule minyaka ingamashumi idlulileyo, kukho into etshintshileyo.
Utshintsho lwemozulu luyichaphazela kakubi le ntaka. Yenza njalo ngendlela yokuba iinkunzi ezinelona ndawo lincinci zisinde ngaphezulu kunezo zinamabala amakhulu kwaye banabantwana abaninzi.
Ifayile yokubambaUFicedula albicollis) yintaka edlulayo, eyaziwa njengeentaka. Ayidluli kwi-18 yeegram ngokobunzima, ihlala kwindlwana esemantla nasembindini weYurophu, apho ibaleka khona xa kuphela ihlobo, isabela eAfrika. Inika i-dimorphism enkulu yesini. Amabhinqa angwevu ngombala, ngelixa amadoda edibanisa abamnyama nabamhlophe ngokungathi babulala iminenga okanye iipandas. Ukongeza, bazisa indawo emhlophe ngaphambili kwentloko, ngaphezulu komlomo. Ubungakanani obukhulu bale ndawo buhambelana ubunini bommandla omkhulu kunye namathuba amakhulu okutsala abantu basetyhini kunye nokuzala.
Iingcali kwezi ntaka bezineminyaka engama-36 bezifunda. Amaxesha okuqala babanjwa kwaye babotshwe ngamakhonkco, babeqinisekisa impumelelo yokuzala ababenayo ngokuba neyona ndawo inkulu. Nangona kunjalo, phakathi kwi-90s, izinto zaqala ukutshintsha kwaye zakhawuleza kule minyaka ilishumi idlulileyo.
Ukuncipha kwebala
Kwisiqingatha sesibini sophando olwenziwe ziingcali, kuye kwafumaniseka ukuba iinkunzi zinendawo encinci engaphambili Sinda ixesha elide kwaye unenzala eninzi. Kuqikelelwa kuphononongo ukuba ukunciphisa kwebala kuba 11% ngaphantsi. Eyona nto ibatsalileyo kukuba bebengazi nokuba bayidibanise na into yokuncipha kwaloo ndawo nokukwazi kwabo ukuziqhelanisa neentaka ngokwabo kunye nezo zinendawo incinci. Kodwa bekungekho ngqiqweni kuba kwinxalenye yokuqala yesifundo, ngabo banelona bala likhulu abasindayo.
Nangona kunjalo, ngoku kumhla wangoku, iikholeji ezinamachaphaza amancinci ngoku zinommandla ngakumbi kwaye zitsalela abantu ababhinqileyo.
Yintoni etshintshileyo?
Iingcali zilawule izinto ezahlukeneyo ezichaza ukunciphisa indawo entloko. Kodwa bahlala nabo banxulumene notshintsho lwemozulu. Kuba amaqondo obushushu ehlabathi anyukile ukusuka kwiminyaka yoo-80 ukuza kuthi ga namhlanje, kwimithombo eshushu (ngexesha lokuthandana kunye neenyanga zokukhwelana) iintaka zenza ngcono ngamachokoza amancinci. Kungenxa yoko le nto ukutshintsha kwemozulu kuya kubeka uxinzelelo ekukhetheni abo banesiphiwo.
“Asiqinisekanga ukuba yintoni edala umahluko wokuba sempilweni, ngaphambili okanye ngoku. Mhlawumbi utshintsho lwemozulu lwenze kwanzima ukuzala ezi ntaka, ngakumbi kuba kufuneka zifudukele e-Afrika. Oku kunokuthetha ukuba iinkunzi ezinamabala amakhulu kufuneka zisebenze nzima ngakumbi ngoku: ukongeza ekondleni amantshontsho azo, la madoda abandakanyeka kungquzulwano oluninzi namanye amadoda. Kukujika kwempumelelo yokuzala. Iindawo ezinkulu zitsala abantu basetyhini, kodwa zicela umngeni nakwindoda. " Iingcali zezi ntaka ziyagqabaza.
Njengesiphelo kutsalwa oko ukuhambela phambili okokuqala nokuhamba ukuya emantla ziziphumo ezibini zotshintsho lwemozulu ezichaphazela iintaka.
