Lokhu kuphakamisa ukuthi imvamisa namandla azo zombili isomiso nezikhukhula zizoqhubeka zikhuphuka ngokuhambisana nezinga lokushisa elijwayelekile, ngakho-ke kubeka amakhulu ezigidi zabantu engcupheni yokuntuleka kwamanzi ahlanzekile. Amadolobha afana neKapa asevele ezwa amandla aphelele ale miphumela.
Unyaka wezi-2018 bekufanele ube usuku iKapa elacisha ngalo ompompi balo, i-Day Zero yokuqala emhlabeni. Izakhamuzi bezibhekene nethuba lokuma ulayini amahora amaningi kompompi ukuze zithole ukudla okulinganiselwe kwansuku zonke okungamalitha angama-25 ngosuku, njengoba umphakathi wawungeke uvunyelwe ukuthola amanzi ngenxa yesomiso esibi kakhulu. Amanye amadolobha amakhulu amadolobha amaningi ayaziwa ukuthi asondela ku-zero emashumini eminyaka ezayo
Kodwa-ke, ososayensi nabacwaningi basebenzela izindlela ezehlukene zokukhiqiza amanzi ahlanzekile ukusuka ezinhlelweni ezincane ukuya ezinhlelweni zezohwebo nezimboni. Izindlela ezisetshenziswa kakhulu zokususa usawoti emanzini manje, yizikhungo zokususa usawoti emanzini ashisayo kanye nezinhlelo zemembrane. Isistimu eshisayo isebenzisa ukushisa. Nakuba amasistimu obhayela emba eqolo futhi edinga imithombo yamandla emba eqolo, le ndlela iwushintshe kakhulu umhlaba ekukhiqizeni amanzi ahlanzekile. Ngakolunye uhlangothi, amasistimu e-Membrane awadingi izindlela eziningi eziyinkimbinkimbi. Ngokusebenzisa ingcindezi kanye nolwelwesi olukhethekile oluneshidi elivuzayo elivumela kuphela amanzi ahlanzekile ukuba adlule kulo. Ngale ndlela, amanzi ahlanzekile akhiqizwa ngokushesha okukhulu.
Amadolobha emhlabeni wonke anenkinga yokungavikeleki kwamanzi. Ukushintsha kwesimo sezulu kubangela ukwanda kwamazinga okushisa amaphakathi kanye nezinkathi eziqhubekayo zezulu elomile. Isidingo ngaphansi kwalezi zimo siyenyuka, kodwa imvula ebambezelekile noma engekho ngesikhathi sonyaka inciphisa ukutholakala, ngakho-ke ibeka ubunzima obukhulu ezinsizeni. Lokhu kushoda kwamanzi ahlanzekile emadolobheni kuyibeka engcupheni yokufinyelela ku-Day Zero yayo. I-Day Zero ngokuyisisekelo isikhathi esilinganiselwe lapho idolobhakazi noma isifunda singakwazi ukuhlinzeka indawo yaso ngamanzi ahlanzekile. Umjikelezo we-hydrologic uxhunyaniswe eduze nezinguquko kuzinga lokushisa lomoya kanye nebhalansi yemisebe, okusho ukuthi isimo sezulu esifudumele siholela emazingeni aphezulu okuhwamuka kanye nokwenyuka kwemvula yoketshezi.
Ngo HID, siyaziqhenya ngokuba enye yezinkampani ezihamba phambili ezisebenzela ukulwa ne-Day Zero mark ezifundeni eziningi emhlabeni okungenzeka zibe sengozini yokushoda kwamanzi. Ithimba lethu labacwaningi lisebenzela ukukhiqiza ulwelwesi lwekhwalithi ephezulu oludinga amandla amancane ukuze luvune amanzi okuphuza ahlanzekile. Sikhuthaza umhlaba ukuthi ulondoloze kakhulu insiza eyigugu futhi uhlanganyele futhi ulwe ne-Day Zero emhlabeni wonke.
