Inkinga yentengo yezindlu nokunye okuhlukile kwezindlu ezingaphansi komhlaba
…Ingabe izindlu ezingaphansi komhlaba zizozixazulula izinkinga zezindlu zaseToronto, eNew York, eHong Kong, eLondon nokunye okunjalo?

Lapho uqeda ukufunda lesi sihloko, inani labantu emhlabeni liyobe selinyuke ngabantu abangaphezu kuka-4,000 7.5. Isibalo sabantu emhlabeni wonke manje sesicishe sibe yizigidi eziyizinkulungwane ezingama-200,000, futhi cishe kuzalwa izingane ezisanda kuzalwa ezicishe zibe ngu-80 nsuku zonke kanye nenani elimangalisayo lezigidi ezingama-2025 ngonyaka. Ngokwezibalo ze-UN, ngo-8, abantu abangaphezu kwezigidi eziyizinkulungwane ezingu-XNUMX bazobe belwela indawo ebusweni bomhlaba.
Inselele enkulu ebangelwa yilokhu kwanda kwabantu okudidayo yizindlu, nazo ezingezinye zezidingo eziyisisekelo zohlanga lwesintu. Le nselelo inkulu kakhulu ezindaweni ezithuthuke kakhulu njengeTokyo, New York, Hong Kong, New Delhi, Toronto, Lagos neMexico City.
Ukwenyuka kwesivinini sezindiza emananini ezindlu kula madolobha kubhekwe kakhulu. Ukufuna izisombululo sekuzophela amandla.
Njengoba izintengo zezindlu zisezingeni lamarekhodi emadolobheni amaningi amakhulu, inketho yezindlu ezingaphansi komhlaba njengenye indlela esebenzayo ayisesona nje isihloko senganekwane yesayensi noma ukuphupha kosuku lobuchwepheshe bezakhiwo.
I-Beijing inemakethe yezindlu ebiza kakhulu emhlabeni, lapho intengo yendlu emaphakathi ihamba cishe ku-$5,820 imitha-skwele ngayinye, igxuma ikhuphuke cishe ngo-30% onyakeni owodwa e-Shanghai. Futhi i-China ibone ukunyuka okungaphezulu kakhulu kwama-40% emananini ezindlu ngonyaka odlule.
ILondon ayaziwa nje ngomlando wayo ocebile; idume futhi ngamanani ayo ezindlu eziphakeme. Isilinganiso senani lentengo yezindlu edolobheni senyuke ngo-84% - sisuka ku-£257,000 ngo-2006 saya ku-£474,000 ngo-2016.
Noma yini ekhuphukayo, ingase ingehli njalo!
Amanani ezindlu aphezulu abhebhezelwa ukuthuthukiswa kwezentengiselwano, abatshalizimali bezindlu kanye nokufudukela emadolobheni. I-UN ibike ukuthi minyaka yonke, cishe abantu abayizigidi ezingu-70 bathuthela emadolobheni amakhulu besuka ezindaweni zasemaphandleni, okwenza kube nenselele enkulu yokuhlela amadolobha.
Ukufudukela emadolobheni akubonisi noma yikuphi ukuthambekela kokwehla. Inani labantu basemadolobheni emhlabeni lilinganiselwa ukuthi lingaphezu kwezigidi eziyizinkulungwane eziyisithupha ngo-2045.
Uma abantu bebaningi, iba nkulu ingcindezi ezindlekweni zengqalasizinda kanye nezindlu. Kuyinto yezomnotho elula. ITokyo inezakhamuzi ezirekhodiwe eziyizigidi ezingu-38, okuyenza ibe idolobha elikhulu kunawo wonke emhlabeni. Ilandelwa eduze iDelhi enabangu-25 million. I-Shanghai esendaweni yesithathu inezigidi ezingu-23. I-Mexico City, i-Mumbai ne-São Paulo ngayinye inabantu ababalelwa ezigidini ezingama-21. Abantu abayizigidi eziyi-18.5 bampintshene ku-Apple enkulu yaseNew York.
Lezi zinombolo ezinkulu zifaka ingcindezi enkulu ezindlini. Amanani nezakhiwo zombili ziyakhuphuka, uma kubhekwa umkhawulo wemvelo womthombo womhlaba. Amadolobha amaningi athuthuke kakhulu nawo anemithetho eqinile yokuhlela amadolobha okwenza umhlaba ube yindlala kakhulu. I-Toronto, isibonelo, inenqubomgomo ye-Ontario Green Belt evikela cishe amahektha ayizigidi ezimbili ekuthuthukisweni kwezentengiso ukuze yonke leyo ndawo ihlale iluhlaza.
Izindlu ezingaphansi komhlaba seziba yinketho ekhangayo enanini elikhulayo lezindawo. Umbiko we-BBC Future ulinganiselwa ezigidini ezi-2 abantu asebevele behlala ngaphansi komhlaba eChina. Elinye idolobha lase-Australia nalo linabantu abangaphezu kuka-80% abahlala ngaphansi komhlaba.
ELondon, kwakhiwe amaphrojekthi amakhulu angaphansi kuka-2000 angaphansi komhlaba kule minyaka eyi-10 edlule. Angaphezu kwezigidi ezintathu amathani ambiwe kulolu hlelo. Izakhiwo ezingaphansi kwezigidigidi ziba yingxenye yezakhiwo ezisenkabeni yeLondon.
UBill Seavey, iNhloko ye-Greener Pastures Institute nombhali we Ungalokothi Ungabi Nakhaya (ngaphambili Amaphupho Asekhaya Ngezikhathi Ezinzima) futhi Ubudlelwano base-U.S/Canada, ungummeli onamandla wezindlu ezingaphansi komhlaba nezinye. UBill wathi, "Izindlu ezingaphansi komhlaba zihlakaniphile ngokobuchwepheshe, ikakhulukazi uma kubhekwa indawo ezungezile, kodwa zisadinga indawo yokwakha--kodwa, zingaba zincane edolobheni elikhulu njengoba igceke noma izingadi zingase zibe phezulu phezulu. Lokho kungase kunciphise. izidingo zesiza sokwakha ziyingxenye. Kodwa izikhulu eziningi zingakuphikisa. Iningi labahleli basemadolobheni abacabangi ngendlela entsha, futhi abakhi ngokuvamile banesithakazelo kuphela ezindlini ezisezingeni eliphezulu futhi babalekela izindlu 'ezithengekayo' ngokujwayelekile--i-red tape eningi, hhayi inzuzo eyanele."
UBill waphawula: “Ngokuthakazelisayo, ezinye izindlela zokwakha ngokuvamile zibhekwa njengeziphansi kunezindlu zozimele, kodwa ziphakathi kwezindlu ezinengqondo nezingabizi kakhulu laphaya.
Ingabe izindlu ezingaphansi komhlaba zizoba yimpendulo yokugcina enkingeni yentengo yezindlu ephezulu?
