Ingca yolwandle. Wakha weva ngayo?

Sithetha kakhulu ngengca yolwandle apha eOcean Foundation. Kodwa yintoni kanye kanye kwaye kutheni ibaluleke kangaka?

Ingca yolwandle zizityalo ezidubulayo ezikhula kumanzi angekho nzulu ngaselunxwemeni nasemachibini. Cinga ngengca yakho yangaphambili… kodwa ngaphantsi kwamanzi. La madlelo adlala indima enkulu kwiinkonzo ze-ikhosistim, ukuthathwa kwekhabhoni kunye nokomelela konxweme. Basenokungabi newonga lodumo lwekorale, kodwa babaluleke ngokulinganayo kwaye basengozini ngokulinganayo.

Yintoni eKhethekileyo ngeSeagrass?
Zibaluleke kakhulu kubomi baselwandle, impilo yolwandle kunye noluntu lwaselunxwemeni. Isityalo esikhula kancinci sisebenza njengendawo yokugcina iintlanzi ezisakhulayo, sibonelela ngokutya kunye nekhusi de zilungele ukufuduka, ngokuqhelekileyo ukuya kwikorale ekufutshane. Ihektare enye yengca yolwandle ixhasa iintlanzi ezingama-40,000 kunye nama-50 ezigidi zezilwanyana ezincinci ezingenamqolo. Ngoku yingingqi enabantu abaninzi. Ingca yolwandle yenza isiseko sewebhu ezininzi zokutya. Ezinye zezilwanyana zaselwandle esizithandayo zithanda ukutya ingca yolwandle, kubandakanywa ufudo lwaselwandle olusengozini yokuphela kunye neemanatee ezingumthombo wokutya ophambili kubo.

Ingca yolwandle ibalulekile kwimpilo yolwandle lulonke kwaye iyinxalenye ebalulekileyo yesisombululo kutshintsho lwemozulu. Esi sityalo sihle sinokugcina ikharbhon eyiphinda kabini ihlathi elisemhlabeni. Uyivile lonto? Ngokuphindwe kabini! Ngelixa ukutyalwa kwemithi kulinyathelo eliya kwicala elililo, ukubuyisela nokutyalwa kwengca yolwandle yindlela esebenzayo kakhulu yokuhluthwa kwekhabhoni kunye nokunciphisa iziphumo ze-asidi yolwandle. Kutheni ubuza? Ewe, kukho ioksijini encinane kumhlaba omanzi, ngoko ke ukubola kwezinto zezityalo eziphilayo kucotha kwaye ikharbhoni ihlala ivaleleke kwaye yomelele ixesha elide. Iingca zolwandle zihlala ngaphantsi kwe-0.2% yeelwandle zehlabathi, kodwa zinoxanduva lokungaphezulu kwe-10% yayo yonke ikhabhoni engcwatywa elwandle minyaka le.

Kuluntu lwengingqi, ingca yolwandle ibalulekile ekomeleleni konxweme. Amadlelo angaphantsi kwamanzi ahluza izingcolisi emanzini kwaye abonelela ngokhuseleko kukhukuliseko lonxweme, izaqhwithi kunye nokunyuka kwamaqondo olwandle. Ingca yolwandle ibalulekile kungekuphela nje kwimpilo yendalo yolwandle, kodwa nakwimpilo yezoqoqosho kwimimandla eselunxwemeni. Babonelela ngomhlaba ochumileyo wokuloba ngokuzonwabisa kwaye bakhuthaza imisebenzi yabakhenkethi, efana nokuntywila emanzini kunye nokuntywila emanzini. EFlorida, apho ingca yolwandle ichumile, kuqikelelwa ukuba inexabiso lezoqoqosho leedola ezingama-20,500 ngehektare nganye kunye nenzuzo yezoqoqosho kwilizwe liphela ezibhiliyoni ezingama-55.4 zeedola ngonyaka.

Izoyikiso kwi-Seagrass

Esona sisongelo kwingca yolwandle sithi. Zombini izinto ezinkulu nezincinci ezenziwa ngabantu, ukusuka kungcoliseko lwamanzi kunye nokufudumala kwehlabathi ukuya kwimivalo yepropeller kunye nokumiswa kwezikhephe, zisongela amadlelo engca yolwandle. I-Prop scars, umphumo wepropeller ejikayo njengoko isikhephe sihamba phezu kodonga olungekho nzulu sisika iingcambu zezityalo, zoyikeka ngakumbi njengoko izibazi zihlala zikhula zibe ziindlela. Imingxunya evuthuzayo yenziwa xa inqanawa isiba phantsi kwaye izama ukucima umbane kumandlalo wengca yolwandle engekho nzulu. Ezi zenzo, ngelixa zixhaphakile kumanzi aselunxwemeni e-US, kulula kakhulu ukuthintela ngokufikelela kuluntu kunye nemfundo yabahambi ngenqanawa.

Ukubuyiswa kweengca zolwandle ezinezikrweqe kungathatha ixesha elingangeminyaka eli-10 kuba xa ingca yolwandle ithe yancothulwa, ukhukuliseko lommandla oyingqongileyo selukufuphi. Kwaye ngelixa iindlela zokubuyisela ziphuculwe kule minyaka ilishumi idlulileyo, kuhlala kunzima kwaye kuyabiza ukubuyisela iibhedi zengca yolwandle. Cinga ngawo wonke umsebenzi oya ekutyaleni ibhedi yeentyatyambo, uze ucinge ukuba uyenza ngaphantsi kwamanzi, kwigiya ye-SCUBA, kwiihektare ezininzi. Yiyo loo nto iprojekthi yethu, iSeaGrass Grow ikhethekile. Sele sinazo iindlela zokubuyisela ingca yolwandle.

Ingca yolwandle ifuna wena! Nokuba uhlala elunxwemeni okanye hayi unganceda.

1. Funda ngakumbi malunga nengca yolwandle. Thatha usapho lwakho elunxwemeni kunye ne-snorkel kwiindawo eziselunxwemeni! Iindawo ezininzi kulula ukufikelela kuzo kwiipaki zoluntu.
2. Yiba ngumqhubi wenqanawa onoxanduva. Ukugrunjwa kwe-Prop-dredging kunye ne-seagrass scarring yimpembelelo engeyomfuneko kwimithombo yendalo onokuyilawula. Funda iitshathi zakho. Funda amanzi. Bazi ubunzulu kunye noyilo lwakho.
3. Ukunciphisa ungcoliseko lwamanzi. Gcina isithinteli sezityalo ecaleni konxweme lwakho ukunqanda ungcoliseko ukuba lungangeni kwiindlela zethu zamanzi. Oku kuya kunceda ukukhusela indawo yakho kukhukuliseko kunye nokucotha kwamanzi ezikhukula ngexesha lezaqhwithi.
4. Ukusasaza ilizwi. Zibandakanye nemibutho yasekuhlaleni ekhuthaza ukukhuselwa kwendalo kunye nokufundisa ngengca yolwandle.
5. Nikela kwintlangano, efana ne-TOF, eneendlela zokubuyisela ingca yolwandle.

Yintoni eyenziwe yi-Ocean Foundation kwingca yolwandle:

1. Ingca yolwandle iyakhula – Iprojekthi yethu yokuKhulisa iSeaGrass ixhasa ukubuyiswa kwengca yolwandle ngeendlela ezahlukeneyo zokubuyisela kwakhona kuquka ukuzinzisa intlenga engadityaniswanga kunye nokufakela ingca yolwandle. Nikela namhlanje!
2. Ukufikelela eluntwini kunye nothethathethwano – Sivakalelwa kukuba oku kubalulekile ukunciphisa iindlela eziyingozi zokukhwela isikhephe kunye nokusasaza iindaba ngokubaluleka kwengca yolwandle. Singenise isiphakamiso kwi-NOAA ukukhokela iPuerto Rico Seagrass Habitat Education and Restoration programme. Oku kuquka ukuphunyezwa kwenkqubo yeminyaka emibini yolondolozo nokukhusela eya kujongana noonobangela bokonakala kwendawo yokuhlala kwingca yolwandle kwiindawo ezimbini ekujoliswe kuzo ePuerto Rico.
3. Blue Carbon Calculator -Siphuhlise i-carbon calculator yokuqala eluhlaza kunye neprojekthi yethu ye-SeaGrass Khula. Bala unyawo lwakho lwekhabhoni, kwaye ulususe ngokutyala ingca yolwandle.
