Isihloko: I-Cutting-Edge Gas Sensor Technology Monitors Greenhouse Gas Emissions kulo lonke elase-Australia naseThailand
Idethi: Januwari 10, 2025
Indawo: Sydney, AustraliaEsikhathini esimakwe ngezinselelo eziphuthumayo zokushintsha kwesimo sezulu, ukuthunyelwa kobuchwepheshe benzwa yegesi ethuthukisiwe kuba isu elibalulekile ekuqapheni ukukhishwa kwesisi esibamba ukushisa emazweni afana ne-Australia ne-Thailand. Lezi zinzwa ezintsha zisiza ohulumeni, izimboni, nezinhlangano zezemvelo emizamweni yazo yokulandela ukukhishwa kwekhabhoni ngokunembile futhi zenze amasu asebenzayo okunciphisa umthelela wesimo sezulu.
I-Australia, eyaziwa ngezindawo zayo ezinkulu kanye nemvelo ehlukahlukene, ibilokhu igxile kakhulu ekubhekaneni ne-carbon footprint yayo. Ukuthunyelwa kwakamuva kwezinzwa zegesi kuzo zonke izindawo zasemadolobheni nasezifundeni zezolimo kunikeza idatha yesikhathi sangempela mayelana nokukhishelwa kwegesi ebamba ukushisa, okuhlanganisa i-carbon dioxide (CO2), i-methane (CH4), ne-nitrous oxide (N2O). Le datha ibalulekile ekuqondeni imithombo ekhishwayo kanye nezitayela, nokuvula indlela yezinyathelo ezihlosiwe zesimo sezulu.
UNgqongqoshe wezeMvelo wase-Australia u-Sarah Thompson ugcizelele ukubaluleka kwalobu buchwepheshe, ethi, "Ngokutshala imali ezinhlelweni zokuqapha ezithuthukile, singaqonda kangcono ukuthi ukukhishwa kwethu kwekhabhoni kuvela kuphi futhi sithathe izinyathelo ezibalulekile zokufinyelela esihlokweni sethu se-net-zero. Lezi zinzwa azigcini nje ngokuthuthukisa idatha yethu yokusungula kodwa zinika amandla imiphakathi ukuthi ibambe iqhaza emizamweni yokunciphisa ukungcola."
E-Thailand, lapho umkhakha wezolimo ufaka isandla kakhulu ekukhishweni kwesisi esibamba ukushisa, ubuchwepheshe benzwa yegesi bubonakala bubalulekile kukho kokubili ukuqapha kwemvelo kanye nokusimama kwezolimo. Uhulumeni waseThailand wethule uhlelo lukazwelonke lokuthumela izinzwa zegesi emasimini elayisi nasemapulazini emfuyo ukuze kuqashwe ukukhishwa kwe-methane, igesi enamandla ebamba ukushisa ekhiqizwa ngesikhathi kulinywa ilayisi nokugaya izilwane. Lesi sinyathelo siyingxenye yokuzibophezela kwe-Thailand ekunciphiseni ukukhishwa kwegesi ngo-20% kule minyaka eyishumi ezayo.
Usosayensi wezemvelo ozinze eBangkok, waphawula, “Ukwaziswa okunembile ngokukhipha i-methane kuvumela abalimi ukuba basebenzise imikhuba engagcini nje ngokunciphisa umthelela wabo endaweni ezungezile kodwa futhi ethuthukisa ukukhiqiza kwabo. Sisebenzisa izinzwa, singanikeza abalimi ulwazi abaludingayo ukuze balungise imikhuba yabo ngesikhathi sangempela.”
Izinzuzo zobuchwepheshe bezinzwa zegesi zidlulela ngale kokuqapha ukukhishwa kwekhabhoni. Lezi zinzwa zifakwe amandla e-inthanethi Yezinto (IoT), evumela ukuhlanganiswa okungenamthungo nezinkundla ezisekelwe emafini zokuhlaziya idatha. Lobu buchwepheshe buvumela ababambiqhaza ukuthi babelane ngedatha yabo yokukhipha inhlabathi nezigungu ezilawulayo, kube negalelo ekuqondeni okuphelele kokukhipha isisi esibamba ukushisa kazwelonke nakwamanye amazwe.
Ngaphezu kwe-Australia ne-Thailand, amazwe afana ne-Canada, i-United States, namalungu e-European Union nawo asebenzisa ubuchwepheshe obufanayo ukuze kuthuthukiswe imizamo yawo yokuqapha ukukhishwa kwesisi esibamba ukushisa. Lo mkhuba ukhombisa ukuqashelwa okukhulayo kwesidingo sezilinganiso ezinembile zokwazisa izinqubomgomo zesimo sezulu kanye nezinqubo ezizinzile.
Enye yezinzuzo ezibaluleke kakhulu zalezi zinhlelo zokuqapha ukufinyeleleka kwazo kanye nesakhiwo esisebenziseka kalula. Izinzwa eziningi zingasatshalaliswa ngengqalasizinda encane, izenze zilungele izifunda ezikude nezisengozini lapho ukuqapha ngokwesiko kungase kungenzeki. Lokhu kufinyeleleka kubalulekile emazweni asathuthuka, lapho izinsiza zokuqapha imvelo zinganqunyelwa.
Uma sibheka phambili, abacwaningi nabameli bezemvelo bagcizelela ukubaluleka kokwandisa la manethiwekhi wezinzwa emhlabeni wonke. Ukuqoqwa kwedatha enembayo yegesi ebamba ukushisa emhlabeni wonke kubalulekile ekulinganiseni inqubekelaphambili ngokumelene nezivumelwano zesimo sezulu samazwe ngamazwe njengeSivumelwano saseParis.
Njengoba ukuphuthuma kokushintsha kwesimo sezulu kukhula, ukuqaliswa kobuchwepheshe bezinzwa zegesi kusebenza njengesibani sethemba, kuhlinzeka ngemininingwane ebalulekile mayelana negesi kanye nokugqugquzela imizamo yokubambisana ekufezeni ikusasa elisimeme. Ngokutshalwa kwezimali okuqhubekayo nokusungula izinto ezintsha, i-Australia, iThailand, namanye amazwe athatha izinyathelo ezibalulekile zokulwa nokushintsha kwesimo sezulu nokuvikela iplanethi ezizukulwaneni ezizayo.
Lokhu kuguquguquka kwezobuchwepheshe ekuqaphelweni kwegesi ebamba ukushisa akukona nje kuphela ukwehlisa ukungcola kodwa futhi kumayelana nokuguqula indlela imiphakathi ehlanganyela ngayo neqiniso elicindezelayo lokushintsha kwesimo sezulu, ukukhuthaza ukuziphendulela, kanye nokuvula indlela yomhlaba osimeme kakhudlwana.
