I-Australia ifaka izinzwa zekhwalithi yamanzi ku-Great Barrier Reef

Uhulumeni wase-Australia ubeke izinzwa ezingxenyeni zeGreat Barrier Reef ukuze zirekhode ikhwalithi yamanzi.
IGreat Barrier Reef ihlanganisa indawo elinganiselwa kumakhilomitha-skwele angama-344,000 ukusuka ogwini olusenyakatho-mpumalanga ye-Australia.Iqukethe amakhulukhulu eziqhingi nezinkulungwane zezakhiwo zemvelo ezibizwa ngokuthi izixhobo zamakhorali.
Izinzwa zikala amazinga enzika kanye nezinto zekhabhoni ezigeleza zisuka eMfuleni i-Fitzroy ziye e-Keppel Bay e-Queensland.Le ndawo itholakala engxenyeni eseningizimu yeGreat Barrier Reef.Lezi zinto zingalimaza izilwane zasolwandle.
Lolu hlelo luphethwe yiCommonwealth Scientific and Industrial Research Organisation (CSIRO), okuyisikhungo sikahulumeni wase-Australia.Lesi sikhungo sithe umsebenzi usebenzisa izinzwa kanye nedatha yesathelayithi ukukala izinguquko kwikhwalithi yamanzi.
Izinga lemizila yamanzi elisogwini nemaphakathi nezwe yase-Australia isongelwa ukunyuka kwamazinga okushisa, ukufudukela kwabantu emadolobheni, ukugawulwa kwamahlathi kanye nokungcola, kusho ochwepheshe.

U-Alex Held uphethe uhlelo.Utshele iVOA ukuthi ingcekeza ingaba yingozi empilweni yasolwandle ngoba ivimba ukukhanya kwelanga ekujuleni kolwandle.Ukuntuleka kokukhanya kwelanga kungalimaza ukukhula kwezitshalo zasolwandle nezinye izinto eziphilayo.I-Sediment iphinde ihlale phezu kwezixhobo zamakhorali, ithinta impilo yasolwandle lapho.
Izinzwa namasathelayithi azosetshenziswa ukukala ukusebenza kahle kwezinhlelo okuhloswe ngazo ukunciphisa ukugeleza noma ukuchitheka kwezinsalela zomfula olwandle, kusho u-Held.
U-Held waphawula ukuthi uhulumeni wase-Australia usebenzise izinhlelo eziningi okuhloswe ngazo ukunciphisa umthelela wenhlabathi eziphila emanzini.Lokhu kuhlanganisa ukuvumela izitshalo ukuba zikhule ngasemifuleni nakwamanye amanzi ukuze kuvinjelwe ukungena kwenhlabathi.
Izazi zemvelo zixwayisa ngokuthi iGreat Barrier Reef ibhekene nezinsongo eziningi.Lokhu kubandakanya ukuguquka kwesimo sezulu, ukungcoliswa komhlaba kanye nokugeleza kwezolimo.Ulwandle lunwebeka cishe amakhilomitha angu-2,300 futhi lusohlwini lwamagugu omhlaba weZizwe Ezihlangene kusukela ngo-1981.
Ukufudukela emadolobheni kuyinqubo lapho abantu abaningi beshiya izindawo zasemakhaya bezohlala emadolobheni.
