eyiyo yokusetyenziswa kwemithombo yamanzi yenye yeengxaki ezibaluleke kakhulu kwezendalo. Uphuhliso olumandla ezolimo, ishishini lemveliso, uqoqosho ngokubanzi, ukukhula izixeko kunokwenzeka lo gama kugcinwe nokunyusa isitokhwe. Kwindawo yokuqala namhlanje phakathi koluntu inkcitho kukhuseleko nature iindleko ukulondoloza umgangatho wamanzi acocekileyo. Ixabiso lilonke koovimba bayo lidlula ixabiso naluphi na uhlobo feedstock kusetyenziswa amaxesha amaninzi.

Xa inkqubo yotshintsho ngempumelelo yendalo imithombo ebalulekileyo amanzi esemgangathweni. Kwakhona inani ezibalulekileyo kubo. Njengomgaqo, nayiphi na iprojekthi kuhlobo inguqu lwayanyaniswa kakhulu kunye nefuthe kwizibonelelo amanzi elithile okanye kwelinye.

Ngophuhliso olukhawulezayo ukusetyenziswa uqoqosho lwehlabathi "gidrozapasov" ngokunzima kwandisa. Ukusetyenziswa kweminyaka esibhozo ukuya kwelishumi kabini. Ngelo linye ekwandiseni ixesha neqondo kungcoliseko. Ngoko ke, imithombo yamanzi ngokuthe kabi.

Umthamo iyonke kwehayidrosfere mkhulu ngokwaneleyo. Inxalenye encinane yale ncwadi (malunga pesenti ezimbini) ziquka amanzi acocekileyo. Baya kuzuza ngqo abantu.

Eyona nto ibalulekileyo, ezisebenzisekayo kukho ichibi, umlambo, izibonelelo ulwandle ngendlela enye okanye ezinye kumacandelo ezoqoqosho. ukubaluleka Omkhulu kwakhona ukufuma komhlaba kunye esesibhakabhakeni, ezibandayo kunye neendawo eziphakamileyo. Ngenxa yoko, phantse onke amacandelo kwehayidrosfere (ngaphandle izimbiwa amanzi kunye biomass) babonwa imithombo "gidrosyrya". Nangona kunjalo, ixabiso kakhulu ukuba abantu amanzi (ichibi, umlambo, komhlaba). Zisetyenziswa ngokomda kwezolimo, yaye mveliso kunye zasekhaya. River, ichibi kunye namanzi aphantsi komhlaba kwimithombo babonwa ukuba ibe yeyona kufumaneka lula, kube lula ilawulwe. Ukongeza, kumjikelo apho kusoloko kuhlaziywa.

Abantu musa ukusebenzisa amanzi agcinwe ezihambayo. Namhlanje, umntu usebenzisa ngaphantsi kwesinye ekhulwini ngumthamo opheleleyo le kwehayidrosfere. Ngokutsho kweengcali, kukho isoyikiso nje kuphela zengingqi kodwa ukunqongophala jikelele amanzi ukuhlangabezana neemfuno zoqoqosho nendlu.

Obonakalayo kukuba imithombo yamanzi ungenza phezulu, etsala amanani amakhulu kuzo zonke iindawo zaloo kwehayidrosfere. Kule ndawo, umsebenzi osebenzayo owenziwayo kakhulu ngempumelelo. Ngenxa yoko, kwezinye kwiimo kwetyuwa emanzini olwandle kuliwa, ubuchule ukulungiselela ifuthe amanzi equlathwe emoyeni. Ngaphezu koko, inkoliso bazibandakanye koovimba komhlaba. Kunye nale izicwangciso phantsi isicelo yamanzi, okunkonkxiweyo ngo ezihambayo.

Kufuneka kuqatshelwe ukuba nxalenye exabisekileyo "gidrosyrya" akukho ngokulungeleleneyo zisasazwe kumazwekazi. Kakhulu enezibonelelo komhlaba kunye kwamanzi ithathwa ibhanti zemvula. Ingakumbi angayiwayo esasimi kufutshane kwindawo Afrika naseMzantsi Merika. Le ndawo akhawunti kuba phakathi kwamawaka angamashumi amabini anesihlanu ukuya amahlanu amawaka cubic metres lomlambo esipheleleyo malunga neshumi ukuya kumashumi amabini anesihlanu amawaka cubic metres amanzi aphantsi komhlaba ngomntu ngamnye ngonyaka. National Water Resources amazwe sabutropikhi lommandla langasezantsi epholileyo kwaye emvula Asia baye umqulu izihlandlo ezilishumi ezincinane. Ukungakwazi aqine ingqalelo e Arabia, Afghanistan, weSahara, kumzantsi Central Asia. Isiqingatha yomntla nefumileyo yaye zone, baba ziingcathu ine nokufumaneka kwamanzi avareji. Apha, umthamo yokumpompoza iyonke ngaphezu kwamashumi amabini anesihlanu amawaka cubic metres umntu ngamnye ngonyaka ngamnye. Kumntla-mpuma eRashiya, kwakunye imimandla yomntla ngokufumaneka kwamanzi eCanada ngaphezu kwesinye ikhulu lamawaka cubic metres abalekayo iyonke ngomntu ngamnye ngonyaka. On indawo eyodwa Australia. Ngaphandle kwento yokuba yonke zwekazi amanzi amancinci ngokwaneleyo, izalathi si zokunikwa avareji nokufumaneka kwayo amanzi ingaphezulu kwe-avareji ixabiso jikelele.
