Njengoba ukungavikeleki kokudla kuqhubeka nokuba yinkinga enkulu, abacwaningi baye bahlola izixazululo ezihlukahlukene, kuhlanganise nokulima emanzini. Ama-Kelps, okuyizitshalo zasolwandle ezinkulu, ayindlela ethembisayo yale njongo, njengoba enikeza amandla amakhulu okuhlinzeka ngokudla ngenkathi enciphisa imiphumela yokushintsha kwesimo sezulu. Nokho, ucwaningo olwengeziwe luyadingeka ukuze kwehliswe izindleko.

Ukulima kwe-Kelp ngesimo sezulu

Intshisekelo yokutshala i-kelp yokudla, imithi, nokunakekelwa komuntu siqu, kanye ne-biofuel kanye ne-bioplastics, iyakhula emhlabeni jikelele. Ngokocwaningo olwenziwa yi-Wageningen University e-Netherlands, ukutshalwa kwamapulazi ezikhula zasolwandle ahlanganisa indawo engamakhilomitha-skwele ayi-180,000, cishe elingana nobukhulu beSifundazwe sase-Washington, kungase kunikeze amaprotheni anele ukufeza izidingo zamaprotheni zabo bonke abantu bomhlaba. Ngaphezu kwalokho, ukulima i-kelp akudingi amanzi noma umanyolo. Ngakho-ke, ayiqhudelani nokunye ukusetshenziswa komhlaba futhi idinga ukulungiswa okuncane. 

Ukukhula kwezimila zasolwandle kungenye yezindlela eziphumelela kakhulu zokuthungatha isikhutha (CO2). Ukwengeza, inyusa amazinga e-pH olwandle, ivuselela imvelo yasolwandle futhi ilwe ne-asidi yolwandle. Ukwethula inani elincane lezinhlobo zama-algal abomvu i-Asparagopsis taxiformis ekudleni kwezinkomo nakho kunganciphisa ukukhiqizwa kwe-methane kusuka ezinkomeni zenyama ngamaphesenti angama-99.

Imizamo eminingi ivukile mayelana nomqondo. Iziqalo ezifana ne-Kelp Blue kanye ne-Sea6 zigijima amapulazi angaphansi kwamanzi ukuze zivune ukhula lwasolwandle lwezimpahla zabathengi, ama-biofuels, nama-bioplastics. Ngokufanayo, i-Australian Seaweed Institute ibambisene nezinhlangano eziningi zocwaningo ukusebenzisa izimila zasolwandle ukulwa nezinkinga zemvelo, okuhlanganisa nokukhipha i-CO2 ne-nitrogen ku-Great Barrier Reef. Ngaleso sikhathi, i-Cascadia Seaweed ihlanganisa i-algae ekudleni futhi isebenza nemiphakathi yendabuko nezizwe.

Umthelela ophazamisayo 

I-Kelp iya ngokuya iduma njengomthombo wokudla ngenxa yokuqukethwe kwayo kwamaprotheni amaningi, ukusimama kwemvelo, kanye nemvelo evumelana nezilwane. Ngakho-ke, ukusetshenziswa kwayo ekukhiqizeni ukudla cishe kuzoqhubeka kwanda. Ngaphezu kwezinzuzo zako njengomthombo wokudla, ukulima i-kelp nakho kunamandla okudala amathuba emisebenzi emiphakathini yendabuko egudle ugu futhi kukhuthaze ukuthuthukiswa komnotho kulezi zindawo. Ngaphezu kwalokho, ukukhiqizwa kanye nokusetshenziswa kwe-bioplastics etholakala ku-kelp nakho kulindeleke ukuthi kwande.

Intshisekelo ekhulayo emithonjeni yamanzi yokudla kanye nokuthathwa kwe-CO2 kulindeleke ukuthi kuphumele ocwaningweni olwandisiwe kule ndawo. Nakuba kungaqinisekwa ukuthi ukugcwala kwekhabhoni kuzokwehla ngezinga elingakanani, kusobala ukuthi imvelo emikhulu yasemanzini izothinteka ngezindlela ezingalindelekile. Ukuze kuthathwe ngempumelelo ukhula lwasolwandle ludinga ukuvunwa; ngaphandle kwalokho, ikhabhoni izokhishwa njengoba ibola. 

Kodwa-ke, ukukhula kwezimila zasolwandle eziningi kakhulu kungaba nomthelela omubi ngokumunca imisoco eminingi olwandle nokuvimbela ukukhanya, ngaleyo ndlela kuphazamise ezinye izimiso zemvelo. Izindleko ezihlobene nokulima i-kelp okwamanje ziphezulu futhi. Naphezu kwezingozi ezihlobene nokulima kwe-kelp, izinzuzo ezingaba khona ziyenza ibe indawo ethembisayo yokuhlola. Iziqalo eziningi cishe zizosebenzisana nezikhungo zocwaningo ukwandisa amandla e-kelp nokuthi ingaguqulwa kanjani ibe yimikhiqizo ehlukahlukene.

Imithelela yokulima i-kelp ngesimo sezulu

Imithelela ebanzi yokulima i-kelp esimweni sezulu ingabandakanya:

• Izinguquko emithethweni kanye nezinhlaka zokuphatha, njengoba ohulumeni besebenzela ukuphatha nokukhuthaza ukukhula kwemboni. Lezi zinguquko zihlanganisa ukulawula ukuvikela ukulima ngokweqile kanye nemvelo. 
• Ukukhuthaza ukuthuthukiswa kobuchwepheshe obusha bokuvuna, ukucubungula, nokusebenzisa i-kelp.
• Izinga lempilo elingcono kanye nokwehla kwezinga lobumpofu emadolobheni nasezigodini ezingasogwini njengoba imisebenzi yasolwandle ikhula, okungasiza ekuxazululeni ukuntuleka kwemisebenzi kanye nokuntuleka kwemisebenzi.
• Ukugqugquzelwa kokubandakanyeka komphakathi nokusebenzisana, njengoba abalimi besebenza ndawonye ukubhekana nezinselele ezifanayo namathuba.
• Ukuhlukahluka kwezomnotho wendawo, okunganciphisa ukuncika ezimbonini ezizodwa futhi kwandise ukusimama kwendawo.
• Ikhwalithi yamanzi ethuthukisiwe kanye nendawo yokuhlala engcono yezilwane zasolwandle.
• Ukuncipha kokukhishwa kwegesi ebamba ukushisa ekufuyweni.

Imibuzo okufanele icatshangelwe

• Ohulumeni bangazisekela kanjani ezinye izimboni zokudla njengokulima i-kelp?
• Yiziphi ezinye izinselelo ezingase zibe khona zokulima i-kelp?
