Asi mvura nyika kusingadzivisiki todzokera ose gore, uye kuramba hwandaiva upenyu pasi redu, vanhu anofanira kushanda zvikuru nesimba.

The chidzoke matambudziko aya zvinoita kwete chete kuti kuipa kwezvakatipoteredza ezvinhu Kunyanya, inokudza kwepasi, zvichiita kuti zvishoma nezvishoma kwemvura mvura kubva pemvura nyika, asi kukura vepasi. Non-kufanana nokuparadzirwa mvura pamusoro munharaunda makondinendi uye zvitsuwa kunotungamirira mvura kwezvokudya mune dzimwe nyika. Kunyatsoyeuka zvaakareva munyika dzakadai Kuwait, Libya, Oman, Brazil uye dzimwe nyika dziri Central Africa.

guru nyika mvura zvinhu zviri kusimbiswa Brazil, Russia, USA uye Canada.

Asi mumakore achangopfuura, vaongorori vari kuramba North uye South matanda zvinoratidza kuti kumhanyisa kuti utsotso kunotungamirira vachiwana rutapudzo nokunwa mvura reserves panyika kuti aigona kutarisana nenjodzi mune ramangwana.

Kuzoponesa nyika mvura mari uye kudzivisa inopinza kwokushatirwa, dzakawanda nerimwe gore kuva zvirongwa inokosha zvakatipoteredza, kuderedza kukuvadza inokudza zvazviri, uye kucheneswa kwemvura yaishandiswa indasitiri.

Chimwe chinetso akakodzera nemvura matura redu - ndiyo yavo kugara kusvibiswa. Kazhinji, kunyanya underdeveloped nyika, tsvina mvura isina kucheneswa uye hwakakanyiwa mvura yakachena dzaizopiwa mumhuri kushandiswa. Somugumisiro, nhamba here akakodzera mvura kwevanhu ipfupi, uyewo dzichiri zvirwere zvakasiyana-siyana.

Water zviwanikwa enyika zvinoda kungwarira chaizvo kubatwa, saka zvipenyu nyika dzakawanda dziri kubhadhara guru yakawanda nguva zvinetso kuvakwa mvura kurapwa nezvinomera indasitiri.

The zvishoma nezvishoma kuomesa nzizi uye madziva akawanda, kunyanya mativi Africa uye South Asia, mashomanana emakore vanotyisidzira zvipenyu nezvakazvipoteredza njodzi munharaunda idzi.

Uyewo, pane zvishoma nezvishoma kwebazi yerudzi rutsva urwu upfumi, sezvo desalination mvura mugungwa. Countries pamwe yakawedzera mvura chishoma, akadai Kuwait, teererai kukuru nyaya iyi uye kutanga chirimwa itsva desalination. Nhasi, mvura yava kunyange mhindu - dzimwe nyika kutenga mvura yakachena kubva States iri ane ndima yacho mwando reserves sezvarakakwirira zvikuru.
