Pfungwa Kushandiswa kwemvura zvinhu ndeimwe matambudziko inokosha zvezvakatipoteredza. The ndichibvunza kukura zvokurima, kugadzira maindasitiri, upfumi seboka, kukura mumaguta runobvira apo kuramba uye kuwedzera mumatanda. Pakutanga nhasi pakati vanhu mari iri zvisikwa kudzivirira ndiwo mari kuchengetedza kwemvura yakachena. Mari reserves ayo akapfuudza kukosha zvimwe mhando feedstock vaishandisa nguva zhinji.

In nedanho anobudirira kuchinja zvakasikwa zvinokosha unhu mvura kupfuma. Zvinokoshawo nhamba vavo. Kazhinji, chero chirongwa pamusoro pemhando kwokushanduka kunonyanya chokuita kukanganisa mvura zvinhu mune rimwe dhigirii kana mumwe.

With kukurumidza kukura nyika upfumi kuparadzwa "gidrozapasov" kuzviita inowedzera. The kudyiwa masere kusvika gumi makore ose kaviri. Panguva iyoyo yakawedzera uye padanho pakusvibiswa. Saka, mvura zvinhu zviri zvishoma depleting.

The zvachose Vhoriyamu hydrosphere riri guru zvakakwana. A chikamu chiduku rino (anenge maviri muzana) vanoumba mvura yakachena. Ivo dzinobatsira vanhu.

Unonyanya kukosha, kushandisika vari mudziva, rwizi, gungwa zvinhu nenzira imwe kana mamwe sectors zvoupfumi. Great kukosha anenge pachivande uye mumhepo mwando, chando polar uye yakakwirira munzvimbo. Saka, vanenge vose hydrosphere zvinoriumba (kunze mvura mamineral biomass) vanoonekwa manyuko "gidrosyrya". Zvisinei, kukosha kune vanhu vari mvura yakachena (nyanza, rwizi, pasi). Ivo zvinoshandiswa zvokurima, uye maindasitiri mudzimba bhora. River, nyanza uye pasi zvinyorwa zviri kuonekwa zvikuru nyore, inogona nyore kudzorwa. Mukuwedzera, muna kutenderera umo kune akaramba achiudza.

Vanhu regai kushandisa mvura yakachena inochengetwa mazitombo echando. Nhasi, munhu anoshandisa asingasviki chimwe muzana zvachose Vhoriyamu hydrosphere. Maererano nenyanzvi, pane ngozi kwete chete kune romunharaunda asiwo munyika yokushomeka mvura kundosangana zvoupfumi uye neveimba zvinodiwa.

Pachena ndechokuti mvura kupfuma kunogona kuita, achikwezva vakawanda munzvimbo dzose hydrosphere. Munzvimbo iyi, basa basa riri kuitwa zvikuru zvinobudirira. Saka, mune dzimwe in mugungwa mvura desalination rinoitwa, unyanzvi akagadzirirwa mvura kukanganisa huri mumhepo. Uyezve, vakawanda vanobatanidzwa pachivande reserves. Pamwe chete urongwa aya pasi kushanda mvura, zvomumagaba mu mazitombo echando.

Zvinofanira kucherechedzwa kuti chinokosha zvikuru chikamu "gidrosyrya" haasi zvakaenzana richiparadzirwa mhiri makondinendi. Most resourced pevhu uye eko ichaongororwa ari Equatorial bhandi. Zvikurukuru akapfuma vari rakamiswa pedyo mapazi ose Africa uye South America. nzvimbo idzi pamusana pakati maviri nezvishanu kusvika makumi mashanu namazana cubic metres yose inowanwa rwizi uye anenge gumi kusvika makumi maviri nezvishanu cubic metres Pasi Pevhu eko pamunhu pagore. National Water Resources subtropical nyika zasi unozvidzora uye achitsva mapazi ose Eurasia vane vhoriyamu kagumi zviduku. Havaratidzi yakasimbiswa munyaya Arabia, Afghanistan, Sahara, kumaodzanyemba Central Asia. Hwokumusoro hafu subtropical uye vakadzikama mapazi ane avhareji mvura Kuwanikwa. Pano, vhoriyamu zvachose kuyerera kupfuura makumi maviri nezvishanu cubic metres pamunhu pagore. Kuchamhembe-kumabvazuva kweRussia, uyewo kuchamhembe mundima Canada mvura Kuwanikwa kunopfuura chimwe namazana cubic metres zvachose eko pamunhu pagore. On nzvimbo chaiyo iri Australia. Pasinei nokuti yose kondinendi iri mvura duku zvakakwana, zviratidzo zvayo avhareji yemvura Kuwanikwa iri kupfuura yose avhareji ukoshi.
