Imithombo yamanzi eplanethi yethu iyisibusiso esibaluleke kakhulu eMhlabeni, esihlinzeka impilo yazo zonke izinto eziphilayo. Ukuhlangabezana nezidingo zazo zonke izidalwa ezisemanzini, kufanele isetshenziswe ngendlela enengqondo. Kunemithombo yamanzi cishe kuwo wonke amazwe omhlaba. Lokhu akuwona nje kuphela amanzi olwandle, imifula, amachibi, kodwa amanzi angaphansi komhlaba kanye namachibi okufakelwa, njengamachibi okugcina amanzi. Uma kwezinye izifundazwe kungekho zinkinga ngokunikezwa kwamanzi, khona-ke kwezinye izingxenye zomhlaba angaba khona, ngoba imigwaqo yamanzi isatshalaliswa ngokungalingani emhlabeni. Ngaphezu kwalokho, kwamanye amazwe kushoda amanzi ahlanzekile (India, China, North America, Middle East, Australia, Nigeria, Bangladesh, Pakistan, Mexico). Ngaphezu kwalokho, namuhla kunenye inkinga yemithombo yamanzi - ukungcoliswa kwezindawo zamanzi ngezinto ezahlukahlukene:
- imikhiqizo kaphethiloli;
- imfucuza yasendlini eqinile;
- amanzi angcolile ezimboni nawomasipala;
- amakhemikhali kanye nemfucumfucu enemisebe.
Esikhathini sokusebenzisa amanzi okunengqondo, ukungcoliswa kwezinto ezinjalo akuvunyelwe, futhi kuyadingeka futhi ukuhlanza yonke imizimba yamanzi.
Izinselelo zokuphathwa kwemithombo yamanzi
Umbuso ngamunye unezinkinga zawo ngemithombo yamanzi. Ukuzixazulula, kuyadingeka ukulawula ukusetshenziswa kwamanzi ezingeni likahulumeni. Ukuze wenze lokhu, kwenziwa imisebenzi elandelayo:
- umphakathi uhlinzekwa ngamanzi okuphuza asezingeni eliphakeme usebenzisa amapayipi amanzi;
- amanzi angcolile ayakhishwa futhi asuswe endaweni yamanzi;
- kusetshenziswa izakhiwo eziphephile zokubacindezela;
- ukuqinisekisa ukuphepha kwabantu uma kunezikhukhula nezinye izinhlekelele zamanzi;
- ukunciphisa ukulimala kwamanzi.
Ngokuvamile, indawo eyengamele ukuphathwa kwamanzi kufanele inikeze ngempumelelo umnotho wezigaba kanye nabantu ngezinsizakusebenza zamanzi ukuhlangabezana nezidingo zasekhaya, zezimboni nezolimo.
Umphumela
Ngakho-ke, izinsizakusebenza zezindawo zamanzi zamazwe ahlukene omhlaba zisetshenziselwa ngenkuthalo hhayi nje ukuhlinzeka abantu ngamanzi, kepha futhi nokuhlinzeka amanzi kuyo yonke imikhakha yezomnotho. Umhlaba unezinsiza ezinkulu olwandle, kepha lawa manzi awakulungele ukusetshenziswa kobuchwepheshe, ngoba anokuqukethwe kasawoti okuphezulu. Kukhona ubuncane bamanzi ahlanzekile emhlabeni, futhi kuyadingeka ukuphatha okunengqondo imithombo yamanzi ukuze anele ukwanelisa zonke izidingo.
