Kugadzirisa kusvibiswa kwepurasitiki mumigwagwa yemvura yeEurope kwatanga kumusoro kwerwizi

Europe yave nezvinangwa zvakajeka pamusoro pekusvibiswa kwepurasitiki. Chirongwa cheEU cheZero Pollution Action Plan chinovavarira panosvika gore ra2030 kuderedza marara epurasitiki mugungwa ne50% uye microplastics inoburitswa muzvakatipoteredza ne30%. Chirongwa chayo chakakura chepurasitiki chakagadzirirwawo kutsigira hunyanzvi, makwikwi uye mabasa., anonyora Francis Zoet, Muvambi pamwe chete uye Mukuru weMashandiro, The Great Bubble Barrier.

Dambudziko riripo iye zvino nderekuitwa kwechirongwa ichi.

European Commission yave pachena kuti, kunyange hazvo paine kufambira mberi kwakaitwa, mikaha mikuru ichiripo mu matanho Nyika dziri nhengo dziri kushandisa kuderedza kusvibiswa kwegungwa. Izvi zvinoratidza mhedziso inoshanda: Europe inoda zvivakwa zvakawanda zvinomisa mapurasitiki asati afamba nerwizi.

KuThe Great Bubble Barrier, ndiro dambudziko ratinoshanda naro zuva nezuva. Tekinoroji yedu inoshandisa chubhu ine maburi pasi penzira yemvura kugadzira keteni remabhuru. Keteni remabhuru iro rinoburitsa simba rinokwira, richiunza purasitiki pamusoro. Nekuisa sisitimu iyi murwizi kana mugero, tinoshandisa kuyerera kwemvura nenzira yechisikigo kutungamira marara kudivi uye mugadziriro yekubvisa. Sisitimu iyi yakagadzirirwa kushanda nguva dzose, muhupamhi hwese uye kudzika kwenzira yemvura, pasina kutadzisa kufamba kwengarava kana kupfuura kwehove.

Chinoita kuti tekinoroji iyi ive yakakosha hachisi chekuti maketeni emabubbles matsva pachawo, asi kuti akagadziriswa kuita sisitimu inoshanda yepurasitiki yekubata. Bubble Barrier ndiyo keteni yekutanga yemabubbles yakagadzirirwa kubata kusvibiswa kwepurasitiki munzizi. Ruzivo rwekutanga runoratidza kuti purasitiki inoyangarara inobatwa ne86%, uye tekinoroji iyi inogona kubata zvinhu zvepurasitiki kubva pa 1 millimeter kusvika 1 mita muhukuru.

KuThe Great Bubble Barrier, tinotenda kuti kugadzirisa kusvibiswa kwepurasitiki kunoda nzira yakazara. Izvi zvinosanganisira kuderedza kugadzirwa kwepurasitiki, kugadzira patsva zvigadzirwa zvezuva nezuva, kushandisa mitemo inoshanda, kuisa mari muhunyanzvi hutsva, uye kudzidzisa veruzhinji. Izvi hazvitsivi chero kuedza ikoko, asi zvinotsigira zvese. Kana mapurasitiki asvika mumvura yakakura, kuunganidzwa kunova kwakaoma uye kunodhura. Ndosaka kupindira kwemvura kuchikosha. Pane kuziva kuri kukura kuti kusangana nezvinangwa zvemvura negungwa zvinoda kufamba kupfuura zvisungo zvemutemo pakugadzira nekushandisa mhinduro dzinoshanda.

Nzizi, migero yemvura uye migero yemvura ndipo panotanga kuoneka shanduko kubva pachinangwa kuenda pakuzadzisa chinangwa.

Mapurojekiti edu anoratidza kuti izvozvo zvinogona kutaridzika sei mukushanda. Kubva muna 2019, sisitimu yedu yekutanga yenguva refu muAmsterdam yakabata mapurasitiki isati yapfuura nemunzira yemvura yeIJ yeguta ichienda kuNorth Sea. Pakazosvika Nyamavhuvhu 2025, kuiswa ikoko kwakanga kwatora mapurasitiki anopfuura miriyoni imwe. Nhasi, tine masisitimu mana ari kushanda: matatu muNetherlands uye rimwe muPortugal. MuHarlingen, Bubble Barrier inobatsira kudzivirira mapurasitiki kuti asapinde muWadden Sea inodzivirirwa neUNESCO. MuVila do Conde, takagadzirisa dhizaini yacho kuti ienderane nemamiriro ekunze, zvichiita kuti ive purojekiti yedu yekutanga murwizi rwemvura.

Mapurojekiti iwayo akaratidzawo kuti tekinoroji inoshanda zvakanyanya kana yakabatana nehutongi hwenzvimbo uye zvivakwa zvemunharaunda. MuAmsterdam, mhinduro yekudzivirira mabubble inoumba chikamu chechirongwa che'Plastic Smart Cities' uye haingoshandiswi chete kudzivirira marara asiwo kuaongorora. Zvinhu zvakaunganidzwa zvinoongororwa uchishandisa nzira yerwizi-OSPAR, iyo inobatsira kuona mhando nekwakabva kusvibiswa kunopinda munzira dzemvura. Izvozvo zvinokosha kune vanoita mitemo. Dambudziko harisi rekungounganidza chete. Kunzwisisa kuti mapurasitiki ari kupinda munzira dzemvura dzeEurope, uye kuatevera kubva kwaanobva, zvakakoshawo.

Kuzivikanwa kune basa rekuitawo. Gore rino, The Great Bubble Barrier yakasarudzwa semutambi wekupedzisira muchikamu cheMvura cheZayed Sustainability Prize - mubairo wekutanga weUAE wepasi rose wemhinduro itsva kumatambudziko epasi rose - kucherechedzwa kwave kureva zvinopfuura kuonekwa chete. Mubairo uyu wakaunza mari kune vese vakakwikwidza mumakwikwi ekupedzisira, neUS $100,000 pamunhu akakwikwidza mumakwikwi ekupedzisira. Kuti pave nemhinduro padanho rekuwedzera, rutsigiro irworwo rwune zvarunoreva. Runobvumira basa riri kutozviratidza mumunda kuti rienderere mberi. Kutenderera kweMubairo wa2027 ikozvino kwavhurika kune vanotumira. Mumunda uyu, mazano akanaka haasi iwo anogumira, asi kugona kuakwidza ndiko. Kuzivikanwa uye maumbirwo emari seMubairo zvinogona kubatsira kuvhara mukaha iwoyo nekupa mhinduro dzakasimbiswa zviwanikwa uye kuonekwa kwavanoda kusvika kune dzimwe nharaunda, nzira dzemvura, uye ecosystems.

Nzira yeEurope yekushandisa mapurasitiki haizobudiriri kuburikidza nekuchenesa kwemvura chete. Ichada kudzivirira kwakasimba, mitemo iri nani, mabhizinesi akatenderera uye masisitimu emarara anoshanda. Asi ichadawo kubata nzira dzemvura sechikamu chemhinduro. Nzizi nemigero zvinobatanidza maguta eEurope nemahombekombe ayo nemakungwa. Idzi mukana wakakosha wekugadzirisa kusvibiswa kwepurasitiki pedyo nekwainobva.
