Njengoba kunikezwe isigaba esilandelayo esiphathelene nemithombo yamanzi, kungamaphesenti amangaki amanzi ahlanzekile agcinwa ngezindlela ezahlukene zokulondoloza?
Context:Imithombo yamanzi iyimithombo yemvelo yamanzi engaba wusizo kubantu, isibonelo njengomthombo wokunikezwa kwamanzi okuphuza noma amanzi okunisela. Amanzi avela "njengamasheya" "nanjengezifufula". Amanzi angagcinwa njengamachibi, umhwamuko wamanzi, amanzi angaphansi komhlaba noma ama-aquifers, neqhwa neqhwa. Kulomthamo wamanzi ahlanzekile omhlaba wonke, kulinganiselwa ukuthi amaphesenti angu - 69 agcinwe ezinguzungeni zeqhwa nasekuvalweni iqhwa; amaphesenti angu - 30 agcinwe emanzini angaphansi komhlaba; bese kuthi amaphesenti angu - 1 asele agcinwe emachibini, emifuleni, emkhathini nasezintweni eziphilayo. Isikhathi amanzi ahlala ngaso esitokisini siyahlukahluka kakhulu: ezinye izikhukhula ezinamanzi ziqukethe amanzi agcinwe izinkulungwane zeminyaka kodwa amavolumu amachibi angashintshashintsha ngesizini, anciphe ngezikhathi ezomile futhi andise ngezikhathi ezimanzi. Ingxenye enkulu yokunikezwa kwamanzi kwezinye izifunda iqukethe amanzi akhishwe emanzini agcinwe ezinqolobaneni, futhi lapho ukuhoxiswa kudlula ukuvuselelwa, izinqolobane ziyancipha. Ngokwezinye izilinganiso, amaphesenti angu-30 amanzi asetshenziselwa ukunisela atholakala ngokukhishwa kwamanzi angaphansi komhlaba, okubangela ukuphelelwa amanzi angaphansi komhlaba.
Kulinganiselwa ukuthi amaphesenti angu - 69 amanzi ahlanzekile agcinwe ezinguzungeni zeqhwa naseqhwa elihlala likhona, amaphesenti angu - 30 emanzini angaphansi komhlaba, kanti amaphesenti angu - 1 asele agcinwe emachibini, emifuleni, emkhathini nasezintweni eziphilayo.
