Inhlolovo Enkulu Kakhulu Emhlabeni Yokungcoliswa Kwasolwandle
Inhlangano kazwelonke yocwaningo yase-Australia i-CSIRO yenza ucwaningo olukhulu kunawo wonke emhlabeni mayelana nokungcoliswa kolwandle. Usebenzisana namazwe emhlabeni wonke ukuwasiza ukuhlola nokunciphisa inani lezinto eziyingozi ezingena olwandle. Lo msebenzi uzobandakanya amazwe amakhulu kakhulu angcolisa ulwandle, okuhlanganisa i-China, i-Bangladesh, i-Indonesia, iVietnam ne-United States, kanye ne-Australia ngokwayo, iNingizimu Korea neTaiwan.
Usosayensi Omkhulu we-CSIRO uDkt. Denise Hardesty uthe le phrojekthi izohlinzeka ngolwazi oluphathekayo mayelana nenani likadoti ongena olwandle kanye nedatha yangempela eqoqwe ogwini nasemadolobhaneni emhlabeni jikelele.
“Kuze kube manje, besithembele ekulinganisweni kwedatha yeBhange Lomhlaba, ngakho kuzoba ngokokuqala ngqa ukuthi kube khona umuntu ohlanganisa iqoqo lamazwe eyedwa ukuze abheke ukuthi ungakanani udoti ongena olwandle,” kusho uHardesty.
Umlando wamanzi we-ballast
Kulethwe kuwe ubambiswano lomhlaba wonke, ohulumeni, abacwaningi nabanye ababambiqhaza, ukushicilelwa kwethulwe ngoJuni 6 ngokuhambisana nomcimbi eNgqungqutheleni ye-UN Oceans eNew York.
Iveza impumelelo enkulu yoHlelo Lobambiswano Lwe-GloBallast ngokubambisana neNhlangano Yezizwe Ezihlangene kanye Nesikhungo Somhlaba Wonke Sezemvelo. Le phrojekthi yethulwa ngo-2007 ukusiza amazwe asathuthuka afuna ukunciphisa ukukhishwa kwezinto eziyingozi kanye namagciwane emanzini e-ballast yemikhumbi.
Amanzi e-Ballast awuketshezi, ngokuvamile amanzi olwandle, asetshenziswa njengempahla eyengeziwe emikhunjini. Inkinga ukuthi ngemva kokusetshenziswa, iyangcoliswa, kodwa ibuyiselwe olwandle.
I-Indonesia ukwenza imikhumbi yayo yokudoba ibonakale
I-Indonesia ibe yizwe lokuqala ukukhulula idatha ye-Vessel Monitoring System (VMS), eveza indawo nomsebenzi wemikhumbi yayo yokudoba ngenjongo yokuthengisa. Zishicilelwe kuplathifomu yamamephu yomphakathi i-Global Fishing Watch futhi zikhombisa ukudoba ngokuthengisa emanzini ase-Indonesia nasezindaweni zoLwandlekazi i-Indian, obekukade kungabonakali emphakathini nakwamanye amazwe. Ungqongqoshe Wezokudoba Nenqubomgomo Yasolwandle uSusi Pujiastuti unxusa amanye amazwe ukuthi enze okufanayo:
“Ukudoba ngokungemthetho kuyinkinga yomhlaba wonke futhi ukulwa nakho kudinga ukubambisana phakathi kwamazwe.”
Imininingwane eshicilelwe kulindeleke ukuthi idikibalise ukudoba okungekho emthethweni futhi kuzuze umphakathi njengoba sikhula isidingo somphakathi solwazi mayelana nomthombo wokudayiswa kwezilwane zasolwandle.
I-Global Ghost Gear yethula indlela yokuqondisa
yethula izixazululo ezisebenzayo kanye nezindlela zokulwa nokudoba izipoki kulo lonke uchungechunge lokuhlinzekwa kwezilwane zasolwandle. Umbhalo wokugcina wakhiwe izinhlangano ezingaphezu kuka-40 ezivela embonini yezilwane zasolwandle.
“Iziqondiso ezisebenzayo zinganciphisa kakhulu umthelela wokudoba izipoki endaweni ezungezile yasolwandle futhi kuvimbele imithelela emibi ezilwaneni zasendle,” kusho uMkhankaso we-World Animal Welfare Oceans and Wildlife uLynn Cavanagh.
Imishini ye-“Ghost” esetshenziselwa ukudoba iyalahlwa noma ilahleke abadobi, okubangela ukulimala kwemvelo yasolwandle. Iqhubeka amakhulu eminyaka futhi ingcolisa izilwane zasendle zasolwandle. Cishe amathani angu-640 ezibhamu ezinjalo kulahleka minyaka yonke.
