Amanqanaba angazange abonwe ngaphambili olwandle lwe-sargassum oluhlanjwe kwiilwandle zaseCaribbean ngo-2018 lubangele iindleko zokucoca eziqikelelwa kwi-120 yezigidi zeedola, ngokutsho koMphathiswa wezoKhenketho kunye noSihlalo we-Global Tourism Resilience and Crisis Management Centre (GRCM), oHloniphekileyo. Edmund Bartlett.
Ukongeza ekususweni okuneendleko eziphezulu, abachaphazelekayo kukhenketho baye baxhalaba ngakumbi malunga nenkangeleko engathandekiyo yokhula lwaselwandle, izikhalazo zabatyeleli kunye nomonakalo wegama elinokwenzeka, uMphathiswa wezoKhenketho uthe.
“Njengabachaphazelekayo abakhutheleyo kwicandelo siyaliqonda ixabiso elingenakulinganiswa lokhenketho kuqoqosho oluzinzileyo noluphumelelayo lweCaribbean. Ukhenketho luhlala luyeyona nto ibalulekileyo yokuphila koqoqosho oluzinzileyo kulo mmandla, ”utshilo uMphathiswa uBartlett xa evula intetho yakhe kwiGTRCM Roundtable eSargassum namhlanje (ngoJulayi 26) kwiYunivesithi yaseWest Indies' kwikomkhulu leNgingqi, eMona.
ICaribbean ngowona mmandla uxhomekeke kakhulu kwezokhenketho kwihlabathi, apho ilicandelo lezoqoqosho eliphambili kumazwe ali-16 kwali-18 eCaribbean kwaye ixhasa imisebenzi ekufutshane ne-3 yezigidi.
Ephawula uqikelelo lokukhula kwe-12% yabakhenkethi abafikayo kulo mmandla ngo-2019, uMphathiswa uBartlett uthe, "Ngaphandle kwezi zalathi zithembisayo kunye nokuqina kwayo (kokhenketho) ngokwembali, sisazi kakuhle ukuba icandelo lezokhenketho libuthathaka kakhulu kwaye lithanda ukuphazamisa. Iminyaka elishumi edlulileyo ibone ukuvela kwezigrogriso ezijongene necandelo. Ezi zoyikiso ziye zabonakala zingalindelekanga kwaye ziyingozi ngakumbi kwimpembelelo yazo kwaye ngokuqinisekileyo kunzima kakhulu ukuzilawula. "
ISargassum yenye yoloyisongelo. Ngokunjalo, i-GTRCM ibone imfuneko engxamisekileyo yokuququzelela ukuhlangana kunye kwabachaphazelekayo bokhenketho lwengingqi kunye nabachaphazelekayo bokusingqongileyo ukuze babelane ngezimvo, iindlela ezingcono kunye nezisombululo ezinokwenzeka kwiziphumo ezibi i-sargassum enokuba nazo kuqoqosho lwesizwe nolwengingqi.
Unjingalwazi uLloyd Waller (ekhohlo), uMlawuli oyiNtloko, iZiko leHlabathi lokuZinzisa uKhenketho kunye neZiko loLawulo lweNgxaki (GRCM); UNjingalwazi uMona Webber, uMlawuli, iZiko leeSayensi zaseLwandle kunye neDiscovery Bay Marine Laboratory; kunye noMphathiswa wezoKhenketho kunye noSihlalo onguSihlalo we-GTCM, oHloniphekileyo. U-Edmund Bartlett (ekunene) uxoxe ngesongelo se-sargassum kukhenketho lweCaribbean ngexesha le-GTRCM Roundtable kwiSargassum kwi-University of the West Indies Region Headquarters, eMona.
Ukusukela ngo-2011, iimethi ezishinyeneyo zokhula lwaselwandle ziye zanda ekuxinaniseni ukuvelisa ibhanti elibude beekhilomitha ezingama-8850 (elinobunzima obuzizigidi ezingama-20 zeetoni zemetric) eyaziwa ngokuba yiGreat Atlantic Sargassum Belt esuka eNtshona Afrika ukuya kuLwandle lweCaribbean kunye neGulf of Mexico. Izazinzulu zikholelwa ukuba oku kugqabhuka kwealgal kuLwandlekazi lweAtlantiki kunye noLwandle lweCaribbean kungabonisa into entsha eqhelekileyo.
Isenzeko se-sargassum kukholelwa ukuba siqhutywa yindibaniselwano yezinto ezenziwe ngumntu kunye nezendalo, kubandakanywa utshintsho lwemozulu kunye nokwanda kobushushu bolwandle; utshintsho kwimimoya yengingqi kunye neepateni zangoku zolwandle; kunye nonikezelo olwandisiweyo lwezondlo ezivela emilanjeni, ugutyulo kunye nezichumisi ezisekelwe kwinitrogen.
Kwiilwandle ezivulekileyo, i-sargassum ibonelela ngeendawo zokuhlala ezibalulekileyo kubomi baselwandle kunye neentaka. Noko ke, xa igutyungelwa ziilwandle iyabola kwaye inuke, ibe ngumqobo wokusingqongileyo noqoqosho. Ukhenketho kuNxweme lweCaribbean lwaseMexico lwehle malunga neepesenti ezingama-35 ngo-2018 ngenxa yokuhlanjwa kwe-sargassum kumgama oziikhilomitha ezingama-480 kunxweme olungacocekanga.
UMphathiswa uBartlett uxelele abathathi-nxaxheba basekhaya nabaphesheya kwi-GTRCM Roundtable ukuba impendulo eyomeleleyo yengingqi kwinqanaba lezopolitiko nelobugcisa ifuneka ngokukhawuleza ukulungisa le ngxaki ye-sargassum eguquka ngokukhawuleza.
"Ukubalwa okusebenzayo kwesi soyikiso kuya kufuna ukuba oorhulumente bezizwe ezahlukeneyo bahlangane ukwenza uphando, ukunciphisa izinto ezinegalelo, ukuchonga ezona ndlela zibalaseleyo zehlabathi kubuchule bokulungelelanisa kunye nokuphuhlisa inyathelo lesayensi elibanzi lokuseka ezona ndlela zisebenzayo zokuqokelela isargassum kwindawo evulekileyo. elwandle ngaphandle kokonakalisa inkqubo yendalo,” utshilo uMphathiswa wezoKhenketho.
Iintetho zenziwe ngu-Andres Bisono Leon kunye noLuka Grey, iMassachusetts Institute of Technology (MIT) iQela loPhando lobuNjineli be-Precision; UNjingalwazi uMona Webber, uMlawuli, iZiko leeSayensi zaseLwandle kunye neDiscovery Bay Marine Laboratory; kunye noMarion Sutton, iOceanographer kunye noMphathi weProjekthi, Qokelela iiSathelayithi zaseKhaya, eFransi.
