Amaphethini okufuduka kwasentwasahlobo, ukusetshenziswa kwendawo yokuhlala, kanye nesimo sokuvikela indawo yokuma sezinhlobo ezimbili zezinyoni zasemanzini eziwohlokayo ebusika e-China njengoba kwembulwa ukulandelela ngesathelayithi.

Abstract:

Izinyoni zasemanzini ezifudukayo zase-East Asia zehle kakhulu kusukela ngeminyaka yawo-1950, ikakhulukazi isibalo sabantu ebusika eChina. Ukongiwa kwemvelo kuthikamezwa kakhulu ukuntuleka kolwazi oluyisisekelo mayelana namaphethini okufuduka kanye nezindawo zokuma. Lolu cwaningo lusebenzisa amasu okulandelela isathelayithi kanye nokuhlaziywa kwendawo okuthuthukisiwe ukuze kuphenywe ukufuduka kwentwasahlobo kwehansi elikhulu elinangaphambili elimhlophe (Anser albifrons) kanye nehansi le-tundra bean (Anser serrirostris) ebusika eduze nomfula i-Yangtze River Floodplain. Ngokusekelwe kumathrekhi angu-24 atholwe kubantu abangu-21 ngesikhathi sentwasahlobo ka-2015 no-2016, sithole ukuthi i-Northeast China Plain ikude kakhulu indawo yokuma esetshenziswa kakhulu ngesikhathi sokufuduka, namahansi ahlala isikhathi esingaphezu kwenyanga engu-1. Lesi sifunda siphinde sathuthukiswa kakhulu kwezolimo, okuphakamisa isixhumanisi esiyimbangela yokwehla kobusika bezinyoni zasemanzini zase-East Asia eChina. Ukuvikelwa kwemithombo yamanzi esetshenziswa njengendawo yokulala, ikakhulukazi leyo ezungezwe umhlaba odinga ukudla okuqinile, kubalulekile ukuze izinyoni zasemanzini ziphile. Ngaphezulu kwe-90% yendawo eyinhloko esetshenziswa ngesikhathi sokufuduka kwentwasahlobo ayivikelekile. Siphakamisa ukuthi izinhlolo-vo zangomuso ezizayo kufanele ziqondise lezi zindawo ukuze kuqinisekiswe ukuhlobana kwazo nezinyoni zasemanzini ezifudukayo ezingeni labantu, futhi indawo ewumgogodla ezindaweni ezibucayi zentwasahlobo kufanele ihlanganiswe kunethiwekhi yezindawo ezivikelwe eduze nomgwaqo. Ngaphezu kwalokho, ukungqubuzana okungase kube khona kwezinyoni nabantu endaweni okunqamule kuyodinga ukucutshungulwa. Ucwaningo lwethu lubonisa ukuthi ukulandelela ngesathelayithi kuhlanganiswe nokuhlaziywa kwendawo kunganikeza imininingwane ebalulekile edingekayo ukuze kuthuthukiswe ukongiwa kwezinhlobo zezilwane Ezifudukayo.
