Izindleko Zokuhlanza I-Sargassum I-Caribbean US $ 120 Million - Bartlett

Amazinga angakaze abonwe okhula lwasolwandle i-sargassum olwakhukhuleka emabhishi aseCaribbean ngo-2018 abangele izindleko zokukhuculula ezilinganiselwa ezigidini ezingu-120 zamaRandi, ngokusho kukaNgqongqoshe Wezokuvakasha kanye NoSihlalo Wokubambisana Wesikhungo Sokulawulwa Kwezokuvakasha Komhlaba Wonke (GRCM), uNom. Edmund Bartlett.

Ngaphezu kokususwa okumba eqolo, ababambiqhaza bezokuvakasha sebekhathazeke kakhulu ngokubukeka kokhula lwasolwandle, izikhalo zezivakashi kanye nokwenzeka komonakalo wesithunzi, kuphawula uNgqongqoshe Wezokuvakasha.

“Njengababambiqhaza abakhuthele emkhakheni siyaliqonda inani elingenakulinganiswa lezokuvakasha emnothweni ozinzile nophumelelayo waseCaribbean. Ezokuvakasha zisalokhu ziyimbangela eyodwa ebaluleke kakhulu yokuphila okusimeme kwezomnotho esifundeni,” kusho uNgqongqoshe uBartlett lapho evula amazwi akhe e-GTRCM Roundtable eSargassum namuhla (Julayi 26) eNyuvesi yaseWest Indies' Region Indlunkulu, eMona.

I-Caribbean iyisifunda esincike kakhulu kwezokuvakasha emhlabeni, lapho iwumkhakha wezomnotho oyinhloko ezifundeni eziyi-16 kwezingu-18 zaseCaribbean futhi isekela imisebenzi ecishe ibe yizigidi ezi-3.

Ephawula izibikezelo zokukhula ngo-12% kwabavakashi abafikayo esifundeni ngo-2019, uNgqongqoshe uBartlett uthe, “Naphezu kwalezi zinkomba ezithembisayo kanye nokuqina (kwezokuvakasha) emlandweni, sazi kahle ukuthi umkhakha wezokuvakasha untekenteke kakhulu futhi uthambekele ekubeni nezinto eziphazamisayo. Eminyakeni eyishumi edlule kube nokuvela kwezinsongo ezibhekene nomkhakha. Lezi zinsongo seziphenduke ezingalindelekile futhi zilimaza kakhulu umthelela wazo futhi kunzima kakhulu ukuzilawula. "

I-Sargassum ingesinye sezinsongo ezinjalo. Ngakho-ke, i-GCRMM yabona isidingo esiphuthumayo sokusiza ukuhlangana ndawonye kwababambe iqhaza kwezokuvakasha kwesifunda kanye nemvelo ukuze babelane ngemibono, izindlela ezingcono kakhulu nezisombululo ezingaba khona zemiphumela emibi i-sargassum eba nayo emnothweni kazwelonke nowesifunda.

USolwazi Lloyd Waller (kwesobunxele), uMqondisi Omkhulu, Isikhungo Sokumelana Nezokuvakasha Komhlaba Wonke kanye Nesikhungo Sokulawulwa Kwezinhlekelele (GTRCM); USolwazi uMona Webber, uMqondisi, Isikhungo Sesayensi Yasolwandle kanye neLabhorethri Yasolwandle yaseDiscovery Bay; kanye noNgqongqoshe Wezokuvakasha kanye NoSihlalo onguSihlalo we-GTCM, uMhlonishwa. U-Edmund Bartlett (kwesokudla) uxoxa ngosongo lwe-sargassum kwezokuvakasha zase-Caribbean phakathi ne-GTRCM Roundtable ku-Sargassum ekomkhulu le-University of the West Indies Region, eMona.

Kusukela ngo-2011, izimila eziwugqinsi zokhula lwasolwandle ziye zanda ngokuminyana ukuze kukhiqizwe ibhande elingamakhilomitha angu-8850 ubude (elinesisindo esingamathani ayizigidi ezingu-20) elaziwa ngeGreat Atlantic Sargassum Belt elisuka eNtshonalanga Afrika liye oLwandle lweCaribbean kanye naseGulf of Mexico. Ososayensi bakholelwa ukuthi lokhu kuqhuma kwe-algal ku-Atlantic Ocean kanye noLwandle lweCaribbean kungasho into entsha evamile.

Isenzo se-sargassum kukholakala ukuthi siqhutshwa inhlanganisela yezinto ezenziwe umuntu kanye nemvelo, kuhlanganise nokushintsha kwesimo sezulu kanye nokwanda kwezinga lokushisa kwamanzi olwandle; ushintsho emimoyeni yesifunda kanye namaphethini wamanje wasolwandle; kanye nokwanda kokutholakala kwezakhamzimba ezivela emifuleni, indle kanye nomanyolo owenziwe ngenitrogen.

Ezilwandle ezivulekile, i-sargassum inikeza izindawo zokuhlala ezibalulekile zokuphila kwasolwandle nezinyoni. Kodwa-ke, uma ikhukhula emabhishi iyabola futhi inuke, ibe wuhlupho kwezemvelo nezomnotho. Ezokuvakasha Ogwini lwaseCaribbean lwaseMexico lwehle ngokulinganiselwa ku-35% ngo-2018 ngenxa yokugeza i-sargassum endaweni engamakhilomitha angu-480 ubude yamabhishi ahlanzekile.

UNgqongqoshe u-Bartlett utshele ababambiqhaza basekhaya nabaphesheya kwezilwandle ku-GTRCM Roundtable ukuthi ukusabela okuqinile kwesifunda kuzo zombili izinga lezombangazwe nezobuchwepheshe kuyadingeka ukuze kubhekwane nale nkinga ye-sargassum eshintsha ngokushesha.

"Ukubalwa ngempumelelo kwalolu songo kuzodinga ukuthi ohulumeni bamazwe ahlukene bahlangane ukuze benze ucwaningo, banciphise izici ezinomthelela, bahlonze izindlela ezingcono kakhulu zomhlaba wonke zokuzivumelanisa nezimo futhi bathuthukise umkhankaso wesayensi ophelele wokusungula izindlela ezisebenza kahle kakhulu zokuqoqa i-sargassum obala. ulwandle ngaphandle kokulimaza imvelo,” kusho uNgqongqoshe wezokuVakasha.

Izethulo zenziwe ngu-Andres Bisono Leon noLuke Grey, iMassachusetts Institute of Technology (MIT) Precision Engineering Research Group; USolwazi uMona Webber, uMqondisi, Isikhungo Sesayensi Yasolwandle kanye neLabhorethri Yasolwandle yaseDiscovery Bay; kanye no-Marion Sutton, i-Oceanographer kanye noMphathi weProjekthi, Qoqa ama-Satellites asendaweni, e-France.
