Izikhongozeli zokuthutha, ezaziwa ngokuba zizikhongozeli zemisebenzi ngokubanzi, zingamaqhawe angadunyiswanga orhwebo lwehlabathi. Ezi zigebenga zesinyithi ziguqule imboni yezothutho ngokubonelela ngendlela esemgangathweni nefanelekileyo yokuhambisa iimpahla kwihlabathi liphela. Masingene kwihlabathi elinomtsalane lezikhongozeli zemisebenzi ngokubanzi kwaye sihlolisise indima yazo ebalulekileyo kurhwebo lwamazwe ngamazwe.
Izikhongozeli zokuthutha ze-Universal zenzelwe ngokukodwa ukumelana nobunzima bokuhamba umgama omde, zikhusela umxholo wazo kuzo zonke iimeko zemozulu, uxinzelelo loomatshini kunye nokuphangwa. Ezi bhokisi zinkulu zesinyithi ziza ngobukhulu obahlukeneyo, kodwa ezona zixhaphakileyo ziintlobo ngeentlobo zeenyawo ezingama-20 kunye neemitha ezingama-40. Zenziwe ngentsimbi eqinileyo okanye i-aluminium kwaye zineminyango ebambekayo ukuze kufikeleleke ngokukhuselekileyo nangokulula kwimithwalo engaphakathi.
Enye yezona nzuzo ziphambili zokusebenzisa izikhongozeli zendalo yonke kukukwazi kwazo ukubekwa ngokulula, oko kuthetha ukuba zinokulayishwa kwiinqanawa, oololiwe okanye iilori ngokufanelekileyo ngaphandle kokuchitha indawo exabisekileyo. Olu hlengahlengiso lwenza lula kakhulu ukuphathwa nokudluliselwa kweempahla, nto leyo eyenza kube lula ukusebenza kwempahla kwihlabathi liphela. Izikhongozeli zenjongo ngokubanzi ziye zaba yindlela ephambili yokuthutha imithwalo emikhulu kunye neempahla ezenziweyo.
Ishishini lokuthumela impahla lixhomekeke kakhulu ekufakweni kweekhonteyina. Ngokwezibalo zamva nje, malunga ne-90% yemithwalo engeyiyo imithwalo emikhulu ithuthwa ngeekhonteyina. Ubungakanani bemithwalo ethuthwa kwihlabathi liphela buyamangalisa, apho kukho izikhonteyina ezingaphezu kwezigidi ezingama-750 ezithunyelwa kwihlabathi liphela minyaka le. Ukususela kwiimoto kunye nezixhobo zombane ukuya kwiimpahla nokutya, phantse yonke into esiyisebenzisayo kubomi bethu bemihla ngemihla isenokuchitha ixesha kwiikhonteyina.
Impembelelo yeekhonteyina ezisetyenziswa kwihlabathi liphela kurhwebo lwamazwe ngamazwe ayinakugqithiswa. Ezi khonteyina zidlale indima ebalulekileyo kwishishini lehlabathi, zivumela amashishini ukuba angene kwiimarike ezintsha kwaye abathengi bonwabele uluhlu olubanzi lweemveliso ezivela kwiikona ezahlukeneyo zehlabathi. Ngenxa yokufakwa kweekhonteyina, iindleko kunye nexesha elifunekayo ukuthutha iimpahla liye lehla kakhulu, nto leyo ebangele ukuba abathengi bafumane iimveliso ezingabizi kakhulu.
Nangona iikhonteyina ezisetyenziswa kwihlabathi liphela ziye zatshintsha izinto, nazo ziza nemingeni. Enye yeengxaki kukusasazwa okungalinganiyo kweekhonteyina kwihlabathi liphela, okubangela ukuhamba korhwebo okungalinganiyo. Ukunqongophala kweekhonteyina kwezinye iindawo kunokubangela ukulibaziseka nokuthintela ukuhamba kakuhle kweempahla. Ukongeza, iikhonteyina ezingenanto zihlala zifuna ukufuduselwa apho zifuneka khona, nto leyo enokubiza kakhulu kwaye ithathe ixesha elide.
Ubhubhane we-COVID-19 uzise nemingeni engazange ibonwe ngaphambili kwishishini lokuthumela iikhonteyina. Njengoko amazwe ebeka imiqathango yokuvalwa kwempahla kwaye ephazamisa uthungelwano lokubonelela, iikhonteyina zijongene nokulibaziseka kunye nokuxinana kwamazibuko, nto leyo ebangela ukungalingani okukhoyo kwaye ibangele ukunyuka kwamaxabiso empahla. Eli shishini kufuneka liziqhelanise ngokukhawuleza neenkqubo ezintsha zempilo nokhuseleko ukuqinisekisa ukuhamba okungaphazanyiswayo kweempahla ezibalulekileyo.
Ukujonga kwixesha elizayo, iikhonteyina ezisetyenziswa ngokubanzi ziya kuqhubeka nokuba ngumqolo worhwebo lwehlabathi. Uphuhliso lwetekhnoloji olufana ne-Intanethi yezinto (IoT) luyadityaniswa kwiikhonteyina, nto leyo eyenza ukuba kulandelelwe kwaye kubekwe iliso kwimithwalo ngexesha langempela. Oku kuqinisekisa ukuba izinto azifihli nto kwaye zikhuselekile kulo lonke uthotho lokubonelela, ngelixa kukwanceda ukucwangciswa kwendlela ephucukileyo kunye nokunciphisa inkunkuma.
Ngamafutshane, iikhonteyina ezisetyenziswa kwihlabathi liphela zitshintshe ishishini lezothutho, nto leyo evumela ukuthuthwa kweempahla ngokufanelekileyo kwihlabathi liphela. Ukubekwa kwazo emgangathweni, ukuqina kwazo kunye nokusebenza kwazo lula kuzenza zibe yinxalenye ebalulekileyo yorhwebo lwamazwe ngamazwe. Nangona imingeni efana nokungalingani kweekhonteyina kunye nokuphazamiseka okubangelwe yibhubhane isaqhubeka, eli shishini liyaqhubeka nokuvelisa izinto ezintsha ukuqinisekisa ukuhamba kweempahla okungaphazamisekiyo kunye nokuqhuba ukukhula koqoqosho lwehlabathi.
