Nigute twaharanira kuringaniza ingufu z’umuyaga w’inyanja hamwe no kubungabunga inyoni z’amazi mu bishanga by’ingenzi byo ku nkombe, ubushakashatsi bwakozwe mu birwa bya Chongming byo mu Bushinwa bw’Uburasirazuba.

Imirima yumuyaga nubundi buryo busukuye bwibicanwa kandi birashobora kugabanya ingaruka z’imihindagurikire y’ikirere. Nyamara, bifite ingaruka zikomeye zibidukikije, cyane cyane ingaruka mbi zinyoni. Inkombe y'Ubushinwa ni igice cy'ingenzi mu ndege yo muri Aziya y'iburasirazuba na Ositaraliya (EAAF) ku nyoni zo mu mazi zimuka, kandi imirima myinshi y'umuyaga yubatswe cyangwa izubakwa muri kano karere bitewe n'amashanyarazi akenewe ndetse n'imbaraga z'umuyaga. Icyakora, ntabwo bizwi cyane ku ngaruka z’imirima minini y’umuyaga yo ku nkombe z’Ubushinwa ku kubungabunga urusobe rw’ibinyabuzima. Ingaruka mbi zimirima yumuyaga ku nyoni zamazi zimara imbeho hano zishobora kugabanuka mugusobanukirwa ikwirakwizwa ryinyoni n’amazi no kuzenguruka umuyaga w’umuyaga muri utwo turere. Kuva muri 2017 kugeza 2019, twahisemo ikirwa cya Chongming nk'ahantu ho kwigwa, kikaba ari hamwe mu hantu hashyushye cyane ku nyoni z’amazi yimuka ku nkombe z’Ubushinwa kandi zikaba zifite ubushobozi buhagije bwo kubyara umuyaga kugira ngo tugere ku mbaraga zirambye, twige uburyo twahuza iterambere ry’imirima y’umuyaga ku nkombe (imirima y’umuyaga ihari kandi iteganijwe kubera ibikorwa by’inyoni). Twagaragaje ibishanga bine by’inyanja bifite akamaro kanini ku nyoni z’amazi dukurikije ubushakashatsi bwakozwe mu murima 16 muri 2017–2018. Twabonye ko amoko arenga 63.16% na 89.86% yinyoni zo mu mazi zagurukaga buri gihe hejuru y’urugomero rwa Chongming Dongtan, aho usanga imirima y’umuyaga iherereye, kandi igakoresha igishanga gisanzwe hagati y’ahantu ho kugaburira ndetse n’ubuturo bw’ubukorikori inyuma y’urwobo nk'ahantu hiyongereye ho kurisha no guteka. Byongeye kandi, hamwe na 4603 ahantu 14 GPS / GSM yakurikiranye inyoni zo mu mazi (inyoni ndwi n’inyoni ndwi) muri Chongming Dongtan muri 2018–2019, twerekanye kandi ko hejuru ya 60% by’inyoni z’amazi zari mu ntera ya metero 800-100 uvuye kuri urwo rugomero, kandi iyi ntera ishobora gusobanurwa nka zone tampon kugirango irinde inyoni z’amazi. Hanyuma, twasanze ibyuka 67 byumuyaga bihari byegeranye n’ibice bine byingenzi by’inyanja ku birwa bya Chongming bishobora kugira ingaruka ku nyoni z’amazi dushingiye ku kuba twabonye akarere ka buffer kugira ngo tubungabunge inyoni. Twanzuye ko gutuza imirima y’umuyaga bitagomba kwirindwa gusa mu bishanga by’ingenzi by’inyanja kugira ngo bibungabunge inyoni z’amazi, ariko kandi no mu karere keza ka bffer gatwikiriye ibishanga by’ubukorikori, nk’ibidendezi by’amazi n’imirima y’umuceri ihurira n’ibishanga by’ingenzi.
