Isibalo sabantu emhlabeni wonke sizokwengeza izigidi eziyizinkulungwane ezimbili emashumini amathathu eminyaka ezayo, sivale ingqophamlando yezigidi eziyishumi ngo-2, kusho i-UN. I-India, okucatshangwa ukuthi izodlula iChina, izohola leli cala.
Umbiko osanda kukhishwa yi-Population Division yoMnyango Wezindaba Zomnotho Nezenhlalakahle we-UN (DESA) onesihloko esithi 'The World Population Prospects 2019: Highlights' ulinganisela ukuthi abantu abayizigidi eziyizinkulungwane ezingu-9.7 bazobe behlala eMhlabeni ngo-2050, okuwukwanda kwababili. billion kusukela manje.
Amazwe ayisishiyagalolunye kulindeleke ukuthi abe necala ngaphezu kwesigamu salokho kuhlasela. Okuhamba phambili yi-India, okubhekeke ukuthi yengeze izigidi ezingama-273 kubantu bayo osevele bayizigidi eziyizinkulungwane eziyi-1.37 futhi idlule eChina, okulindeleke ukuthi inani labantu lehle ngezigidi ezingu-31.4 phakathi kuka-2019 no-2050. Isibalo sabantu baseChina sizoqhubeka nokuncipha futhi kulindeleke ukuthi sifinyelele ku-1.1 billion ngo-2100, kuyilapho i-India kulindeleke ukuthi ibe nezakhamuzi eziyizigidi eziyizinkulungwane ezingu-1.4 ngaleso sikhathi.
INigeria ephume isibili ayisekho kude, kanti kulindeleke ukuthi ingeze abantu abayizigidi ezingama-200 ngo-2050. IPakistan, Ethiopia, Tanzania, Indonesia, Democratic Republic of Congo, Egypt, kanye ne-US ngamanye amazwe ayisikhombisa azobe eshayela leli qembu. ngokwanda kwenani labantu emhlabeni wonke eminyakeni engu-30 ezayo, ngokombiko.
Kodwa ukweqa okukhulu kwenani labantu kuzokwenzeka e-Afrika eseningizimu yeSahara, lapho kuzokhula ngokuphindwe kabili ngo-2050, intuthuko engase icindezele kakhulu izinhlelo zezenhlalakahle ezintekenteke zamazwe.
"Iningi labantu elikhula ngokushesha lisemazweni ampofu kakhulu, lapho ukukhula kwenani labantu kuletha izinselelo ezengeziwe," kusho uSekelaNobhala-Jikelele we-DESA uLiu Zhenmin esikhishwe kwabezindaba ngoMsombuluko.
Nakuba izibalo zimangalisa, ukukhula kwenani labantu kuyehla futhi kulindeleke ukuthi kucishe kume. Okwamanje, isilinganiso senani labantu abazalwa ngowesifazane ngamunye singu-2.5, kodwa ngo-2050 kulindeleke ukuthi sehle siye ku-2.2, okubeka umhlaba onqenqemeni lokuncipha kwabantu. Izinga lokuzalwa kwabantu abangu-2.1 owesifazane ngamunye libhekwa njengelinganele ngokwanele ukusekela inani labantu, okulindeleke ukuthi lifinyelele umkhawulo walo ekupheleni kwekhulu leminyaka lifinyelele ezigidini eziyizinkulungwane ezingu-11.
Isibalo esiphansi sokuzalwa kowesifazane ngamunye sizoshaya kakhulu amazwe angama-55 ahlelelwe ukubona inani labantu lincipha okungenani ngephesenti elilodwa. Iphakethe liholwa yiShayina futhi lilandelwa ngamanye amazwe, amaningi atholakala eMpumalanga Yurophu noma eCaribbean. ILithuania neBulgaria zizoncipha kakhulu, njengoba inani labantu bazo lincipha ngamaphesenti angu-23 ngo-2050. ILatvia, ngokwehla okulinganiselwa ku-22%, ilandelwa yiWallis neFutuna Islands (amaphesenti angu-20), ne-Ukraine (amaphesenti angu-20).
Nakuba abacwaningi behlaba umkhosi ngokwanda okusheshayo kwenani labantu emazweni asathuthuka, baphinde babhekisele enanini elikhulayo labantu abaneminyaka engama-65 nangaphezulu eliwumthwalo onzima kwezomnotho. Nakuba oyedwa kuphela kwabangu-11 oseqenjini leminyaka yobudala, ngo-2050, oyedwa kwabayisithupha uzoba neminyaka engu-65 noma ngaphezulu. Kwezinye izifunda, njengase-Asia, eLatin America, naseNyakatho ne-Afrika, inani labantu abadala kulindeleke ukuthi liphindeke kabili ngo-2050, amanothi ocwaningo.
