Amahlathi azinzileyo lukhetho olufanelekileyo lokutshintsha kwemozulu

amahlathi azinzileyo okutshintsha kwemozulu

Kule mihla yethu kuluntu lwanamhlanje, nokuba uyazi ngakumbi imeko-bume kunye notshintsho lwemozulu okanye hayi, phantse wonke umntu ubona ukugawula imithi kunye nokutshabalalisa amahlathi into ebalulekileyo enegalelo kwiziphumo ezandayo zotshintsho lwemozulu. Ikwaqwalaselwa kwakhona into yokuba ulondolozo kunye nokusetyenziswa okuzinzileyo kwamahlathi ehlabathi kuya kunceda kakhulu ekunciphiseni ukukhutshwa kwegesi yendlu eluhlaza, okanye ubuncinci ukufunxwa kwabo okungcono emoyeni.

Isivumelwano saseParis, Yamkelwa ngamaqela ali-195 kwiNgqungquthela yeNkqubo-sikhokelo yeZizwe eziManyeneyo yoTshintsho lweMozulu ngasekupheleni konyaka ophelileyo, yayiyindawo ebalulekileyo yokuqalisa ukuqaphela ukuba amahlathi abalulekile kwidabi lokulwa utshintsho lwemozulu. Amahlathi azinzileyo asinceda njani kwidabi lokulwa utshintsho lwemozulu?

ukugawulwa kwamahlathi kunegalelo ekukhutsheni igesi yendlu eluhlaza kwaye

Amahlathi kwihlabathi liphela asebenza njengeendawo zokucima ikhabhon. "Bayasisebenzela" ukugcina iigesi zegreenhouse kwi-biomass yakho, inkunkuma kunye nomhlaba. Igalelo lamahlathi kumlo ochasene notshintsho lwemozulu likrele elintlangothi-mbini. Kungenxa yokuba ukugawulwa kwemithi kunye nokuthotywa kwamahlathi esiwenzayo ngemisebenzi yethu yezoqoqosho kuthwala uxanduva oluphakathi kwe-10% ne-12% yazo zonke izinto ezikhutshwayo. Oko kukuthi, kunye nezolimo, zezona zibalulekileyo zikhokelela kubushushu behlabathi.

Ngamanye amagama, amahlathi anokusinceda ukuba sifunxe kwaye sigcine ikhabhoni egqithisileyo emoyeni, kodwa xa imithi isifa, ikhupha i-CO2 edibanisa konke ukukhutshwa. Amazwe anjengeCongo, iGabon, i-Indonesia, iKenya, iMalaysia, iMexico kunye noMzantsi Korea azibophelele ekunciphiseni ukukhutshwa komisi ngaphezulu kwe-25% yamanqanaba esiqhelo emisebenzi. Ngaphaya koko, ngaphezulu kwama-70% ezi zibhambathiso zokuzithandela zibandakanya iintshukumo ezinxulumene namahlathi kunye nokhathalelo olufanelekileyo.

Ulawulo olulungileyo lokutshintsha kwemozulu

amahlathi agawulwa ngenjongo yokulima

Oososayensi bathi ulawulo olufanelekileyo lwezixhobo kunye nokunakekelwa kakuhle kwamahlathi nawo onke amahlathi kunokunceda kakhulu kumlo ochasene notshintsho lwemozulu. Umzekelo, ukunika idatha ukukunceda ufumane umbono, 123 izithole zomthi zikhule kangangeminyaka eli-10 Bangayicenga ikhabhon ekhutshwe ngunyaka wokuqhuba imoto.

Isicwangciso-buchule sokukwazi ukwamkela izicwangciso zophuhliso ezizinzileyo kwimicimbi yezamahlathi sibaluleke kakhulu kumazwe asaphuhlayo, kuba owona mthamo uphakamileyo wokukhutshwa kwekhabhoni ekususeni ihlathi kwenzeka kumazantsi e-hemisphere. Oku ikakhulu kungenxa yokuba imithi zigawulwa ukuze kuvuleke indawo yezolimo. Ngamanye amagama, ukugawulwa kwamahlathi ukuze ukwazi ukutya. Kwezolimo, amazwe angaphuhlanga kakhulu anokufumana ingeniso ngokulima.

Umzekelo woku kukusetyenziswa kweenkuni njengamafutha. Malunga nesinye kwisithathu seentsapho kwihlabathi liphela ziyisebenzisa ekuphekeni ukutya, Ngelixa abanye abantu abazizigidi ezingama-764 bayayisebenzisa ukubilisa nokucoca amanzi.

Iindlela zokunciphisa ukukhutshwa kwekhabhoni

ukugawulwa kwemithi kunokunyusa ukukhutshwa kwekhabhoni

Phantse iipesenti ezingama-75 zeetoni ze-CO2 ezikhutshelwa emoyeni ngokugawula imithi yokuxhaphaza iinkuni, zivela ekuphekeni ukutya. Iikhitshi zala maxesha neziphuculweyo zitshisa iinkuni ezimbalwa, zinceda ukukhupha i-CO2 encinci emoyeni. Oku kunegalelo ekunciphiseni ukukhutshwa kwegesi egreenhouse emoyeni, ingakumbi eAfrika nakwimimandla esemaphandleni yeLatin America.

Kucacile ukuba eyona nto iphambili ekunciphiseni ukukhutshwa kukuzinza kunye nokusetyenziswa kwetekhnoloji yale mihla enceda ukuveliswa kweethanol kwi-biomass enemithi. Sebenzisa iimveliso zeenkuni njengezinto eziluhlaza zokwakha. Sitsho ngokwendalo ukusukela ngokungabatshisi bayayigcina ikhabhoni egcinwe ngaphakathi.
