Nzvimbo: Lima, Peru —Sezvo kudiwa kwekurima hove dzinogara kwenguva refu kuri kukura pasi rose, kuunzwa kwemasensa e chlorine anoramba aripo kuri kuchinja maitiro muindasitiri. Masisitimu aya epamusoro ekutarisa, ayo anovimbisa kunaka kwemvura munzvimbo dzinochengetwa hove, ari kuwana mukurumbira muPeru, United States, nedzimwe nyika, zvichiratidza shanduko huru mukurima hove nehove.
Chlorine inowanzo shandiswa mukurima gungwa kuuraya utachiona mumvura, kudzivirira kupararira kwezvirwere uye kuona hutano hwemhuka dzemumvura. Zvisinei, dambudziko rave riri rekuchengetedza huwandu hwakakodzera hwechlorine pasina kuisa njodzi kuhove. Apa ndipo panoshanda masensa echlorine anoramba aripo nguva dzose. Kusiyana nemasisitimu ekutarisa echinyakare, ayo anongopa kuverenga nguva nenguva, masensa aya anopa data rinogara riripo, renguva chaiyo pahuwandu hwechlorine, zvichibvumira varimi kugadzirisa nekukurumidza sezvinodiwa.
MuPeru, uko kurima hove kwave chikamu chakakosha chehupfumi, kushandiswa kwemasensa aya kuri kubatsira zvikuru. Mapurazi mazhinji ehove ePeru, kunyanya ayo akatarisana neshrimp netilapia, akataura kuwedzera kwehuwandu hwekurarama uye mhando yezvigadzirwa kubva pakubatanidza masensa echlorine anoramba aripo. "Takaona kudzikira kusvika ku30% muhuwandu hwekufa kwehove kubva pakuisa masensa aya," akadaro Eduardo Morales, muridzi wepurazi reshrimp muPiura. "Mhinduro chaiyo inotibvumira kuti tiite nekukurumidza kune shanduko mumhando yemvura, izvo zvakakosha."
Mabhenefiti ezvishandiso izvi zvepamusoro haasi muPeru chete. MuUnited States, mabasa ekupfuya hove mumahombekombe ari kushandisawo tekinoroji iyi. Michael Johnson, nyanzvi yezvebhayoloji yegungwa uye nyanzvi yezvekurima hove iri muFlorida, akatsanangura kuti, "Nekutarisa nguva dzose, mapurazi anogona kugadzirisa kushandiswa kwechlorine, kuderedza mitengo uye kuderedza kukanganisa kwezvakatipoteredza. Izvi zvakakosha sezvo vatengi vachiwedzera kuda pachena uye kuchengetedzeka mukugadzirwa kwehove."
Uyezve, nyika dziri kuSoutheast Asia neEurope dziri kuonawo mabhenefiti ezvishandiso izvi. MuVietnam, uko indasitiri yeshrimp iri kubudirira, varimi vari kushandisa tekinoroji inoita kuti huwandu hwechlorine huve nani, zvichiita kuti kuchengetedzeka kwezvigadzirwa kuve nani uye marara aderedzwe. Panguva iyi, makambani ekuEurope anochengeta hove ari kushandisa tekinoroji yakafanana kugadzirisa mitemo yeEU pamusoro pemasaririra emakemikari muzvigadzirwa zvehove.
Pasinei nekugamuchirwa kwakanaka uku, nyanzvi dzinoti kushandiswa kwakawanda kunoda dzidzo nekudyara mari mukudzidziswa kwevashandi vekurima gungwa. "Tekinoroji iyi pachayo iri nyore, asi kunzwisisa mashandisirwo edata rainopa kunogona kunetsa vamwe varimi," akadaro Dr. Sara Tello, muongorori wekurima gungwa paYunivhesiti yeFlorida. "Masangano ekudzidzisa nekuratidzira zvichave zvakakosha mukubatsira varimi munzvimbo dzakasiyana kushandisa tekinoroji iyi."
Kubatanidzwa kwemasensa echlorine anoramba aripo nguva dzose kunovhurawo mukana wekufambira mberi mukutarisa hunhu hwemvura. Mapoka ekutsvagisa ari kutoongorora mukana wekubatanidza masensa aya nezvimwe zvishandiso zvekutarisa zvakatipoteredza, zvakaita sepH, tembiricha, uye ammonia, kuti vagadzire masisitimu akakwana ekutarisa hunhu hwemvura.
Sezvo indasitiri yekurima hove ichitsvaga kuenzanisa kushanda zvakanaka kwekugadzira hove nekukanganiswa kwezvakatipoteredza, matekinoroji akadai semasensa echlorine anoramba aripo ari kuva akakosha. Kushandira pamwe pakati pevarimi, vaongorori, nevanopa tekinoroji kuchave kwakakosha mukuumba remangwana retsika dzekurima hove dzinogara kwenguva refu pasi rose.
Kunyika dzakadai sePeru neUnited States, shanduko iyi haisi nyaya yekusimudzira goho chete asiwo yekuchengetedza raramo yemamiriyoni evanhu vanovimba nekurima hove, vachiona kuti vanogona kubudirira mumusika wepasi rose unogara uchidikanwa.
