Nguva inotevera paunobatidza pombi, zadza ketero, uye wozvigadzirira kapu yekofi, funga nezvekukosha kwakaita mvura kuupenyu hwedu. Zvingaita sekuti tinoshandisa mvura kunyanya kunwa, kugeza uye kuwacha. Asi makambofunga here nezvokuti imvura yakawanda sei inodiwa pakugadzira zvokudya zvatinodya, zvipfeko zvatinopfeka, uye mararamiro atinorarama?
Somuenzaniso, imwe kapu yekofi yemangwanani inoda marita 140 emvura! Sekutaura kwesangano reFood and Agriculture Organisation reUnited Nations, uku ndiko kuwanda kwazvinoda kurima, kugadzira nekutakura bhinzi inokwana kapu imwe chete.
Patinenge tichitenga muchitoro chegirosari, isu hatiwanzofunga nezvemvura, asi iyi yakakosha sosi chinhu chakakosha chezvizhinji zvezvigadzirwa zvinopedzisira zvave mungoro dzedu dzekutengera.
Mvura yakawanda sei inopinda mukugadzira chikafu?
Zvinoenderana neavhareji yepasi rose, aya ndiwo mangani marita emvura anodiwa kugadzira kilogiramu imwe yezvikafu zvinotevera:
Nyama yemombe - 15415
Nzungu - 9063
Gwayana – 8763
Nguruve - 5988

Madiridziro ekurima anoita chikamu che70% chemvura inoshandiswa pasi rose. Sezvaunogona kuona, yakawanda yemvura inoshandiswa pakugadzirwa kwezvigadzirwa zvenyama, pamwe nekurima nuts. Kune avhareji ye15 litres emvura pakirogiramu yemombe - uye yakawanda yacho inoshandiswa kurima chikafu chemhuka.
Kuenzanisa, kukura michero kunotora zvinooneka zvishoma mvura: 70 malita paapuro. Asi kana muto unogadzirwa kubva kune michero, huwandu hwemvura inopedzwa hunowedzera - kusvika ku190 malita pagirazi.
Asi zvekurima handiyo yega indasitiri inotsamira pamvura zvakanyanya. Mushumo wa2017 unoratidza kuti mugore rimwe chete, nyika yefashoni yakadya mvura yakakwana kuti izadze madziva okutuhwina anosvika mamiriyoni makumi matatu nemaviri eOlympic. Uye, sezviri pachena, kushandiswa kwemvura muindasitiri kuchawedzera ne32% ne2030.
Zvinogona kutora 2720 litres emvura kugadzira T-shirt iri nyore, uye inoda kusvika 10000 litres kugadzira peya imwe yejini.
Asi mvura inoshandiswa kugadzira chikafu nembatya idonhe remugomo zvichienzaniswa nekushandiswa kwemvura mumaindasitiri. Pasi rose, zvidyarwa zvemagetsi zvemarasha zvinodya mvura yakawanda sevanhu bhiriyoni, uye mabhiriyoni maviri mune ramangwana kana zvidyarwa zvemagetsi zvakarongwa zvakatanga kushanda, maererano neGreenpeace.
Ramangwana rine mvura shoma
Nekuti mvura yepasi haina magumo, huwandu hwazvino hunoshandiswa neindasitiri, vagadziri uye vatengi hauna kugadzikana, kunyanya nekukura kuri kuita kwePasi. Maererano neWorld Resources Institute, pachava ne2050 mabhiriyoni evanhu pasi pano ne9,8, izvo zvichawedzera zvakanyanya kudzvinyirira kune zviripo.
Iyo 2019 World Economic Forum Global Risk Report inoisa dambudziko remvura seyechina yakakura kukanganisa. Kushandiswa kwemvura iripo, kuwedzera kwehuwandu hwevanhu uye mhedzisiro yekushanduka kwemamiriro ekunze kunoparadza nyika kune ramangwana iro kudiwa kwemvura kunopfuura kupihwa. Mamiriro ezvinhu aya anogona kukonzera kunetsana nekuomerwa nekuti zvekurima, simba, maindasitiri nedzimba zvichikwikwidzana kuwana mvura.
Huwandu hwedambudziko remvura pasi rose hwakakura, kunyanya zvichitariswa kuti vanhu 844 miriyoni vachiri kushaya mvura yekunwa yakachena uye 2,3 bhiriyoni havakwanise kuwana zvimbuzi zvakaita sezvimbuzi.
