Kushandiswa kweOxygen Yakanyungudutswa Muhunhu hweMvura Yekurima muPhilippines

Nhanganyaya

MuPhilippines, kurima chikamu chakakosha chehupfumi hwenyika, vanhu vanosvika chikamu chimwe muzvitatu vachivimba nako kuti vawane raramo. Nekuwedzera kwekushanduka kwemamiriro ekunze uye kusvibiswa kwezvakatipoteredza, mhando yemvura yekudiridza—kunyanya huwandu hweoxygen yakanyungudutswa (DO)—yakawedzera kukanganisa kukura kwezvirimwa nekubudirira. Okisijeni yakanyungudutswa inokanganisa kwete chete kupona kwezvisikwa zvemumvura asiwo hutano hwevhu nekukura kwezvirimwa. Chidzidzo ichi chinoongorora kuti sangano rekurima remuPhilippines rakanyatsoongorora nekuvandudza huwandu hweoxygen yakanyungudutswa mumvura kuti riwedzere goho uye mhando yezvirimwa.

Nhoroondo yeProjekiti

Muna 2021, kambani yekurima mupunga kumaodzanyemba kwePhilippines yakatarisana nedambudziko rekushaya okisijeni yakanyungudika mumvura yayo yekudiridza. Nekuda kwekushandiswa zvakanyanya kwefetereza nekusvibiswa, matsime emvura akatambura nekushaikwa kwemvura, zvichikanganisa zvakanyanya nharaunda yemumvura uye kunaka kwemvura, izvo zvakaita kuti zvirwere zvezvirimwa zviwedzere uye goho risadzikire. Nekuda kweizvozvo, kambani iyi yakatanga chirongwa chakanangana nekuvandudza kunaka kwemvura nekuwedzera huwandu hweokisijeni yakanyungudika, nokudaro ichikurudzira kukura kwemupunga zviri nani.

Matanho Ekutarisa Nekuvandudza Okisijeni Yakanyungudutswa

1. Sisitimu Yekutarisa Hunhu hweMvura: Mushandirapamwe uyu wakaunza michina yepamusoro yekutarisa hunhu hwemvura kuti iongorore nguva dzose huwandu hweokisijeni yakanyungudika, huwandu hwepH, nezvimwe zvinhu zvakakosha. Neruzivo rwenguva chaiyo, varimi vaigona kuona matambudziko nekukurumidza uye kutora matanho akakodzera.

2. Matekinoroji Ekuvandudza Okisijeni Yakanyungudutswa:

   • Masisitimu eKufefetera: Midziyo yekufemesa yakaiswa mumigero mikuru yekudiridza, zvichiwedzera okisijeni yakanyungudika mumvura kuburikidza nekuunzwa kwemabubble emhepo, nokudaro zvichivandudza kunaka kwemvura.
   • Mibhedha yezvirimwa zvinoyangarara: Minda yezvirimwa inoyangarara (yakadai seduckweed newater hyacinths) yakaunzwa mumvura yekudiridza. Zvirimwa izvi hazvingoburitse okisijeni chete kuburikidza nephotosynthesis asiwo zvinotora zvinovaka muviri, nokudaro zvichidzivisa kuzara kwemvura.

3. Maitiro Ekurima Asina Kushanda Zvakakwana:

   • Vakakurudzira misimboti yekurima zvirimwa zvisina makemikari inoderedza kushandiswa kwefetereza nemishonga yekuuraya zvipembenene, pachinzvimbo chekushandisa manyowa nemishonga yekuuraya zvipembenene kuderedza kusvibiswa kwemvura nekuvandudza kunaka kwemvura.

Maitiro Ekuita

• Kudzidziswa uye Kuparadzira Ruzivo: Bato iri rakaronga misangano yakawanda yekudzidzisa varimi nezvekukosha kwekutarisa hunhu hwemvura uye nzira dzakasiyana-siyana dzekuwedzera huwandu hweokisijeni yakanyungudika. Varimi vakadzidza mashandisirwo emidziyo yekutarisa hunhu hwemvura uye kushandisa masisitimu ekufema.

• Kuongorora nematanho: Chirongwa ichi chakakamurwa kuita zvikamu zvakasiyana-siyana, neongororo dzakaitwa pakupera kwechikamu chimwe nechimwe kuti vaongorore shanduko muhuwandu hweokisijeni yakanyungudutswa uye kuenzanisa goho remupunga.

Mhedzisiro Nemigumisiro

1. Kuwedzera Kunokosha Kwemazinga Eokisijeni Akanyungudutswa: Nekushandisa matekinoroji emhepo uye matekinoroji emuminda inoyangarara, huwandu hweokisijeni yakanyungudika mumvura yekudiridza hwakawedzera neavhareji ye30%, zvichikonzera kuvandudzika kunoonekwa mumhando yemvura.

2. Goho Rakavandudzwa: Nekuwedzera kwehunhu hwemvura, kambani iyi yakawedzera goho remupunga ne20%. Varimi vazhinji vakataura kuti kukura kwemupunga kwakawedzera, kuwanda kwezvipembenene nezvirwere kwakadzikira, uye hunhu hwese hwakawedzera.

3. Mari Inowanikwa Nevarimi Yakawedzera: Kukwira kwegoho kwakaita kuti varimi vakure zvakanyanya, zvichibatsira hupfumi hwemushandirapamwe.

4. Kubudirira Kwekurima Kunogara Kwakagadzikana: Nekukurudzira kurima kwezvirimwa zvisina makemikari uye kutarisira mvura zvakanaka, nzira dzekurima dzemushandirapamwe dzakava dzinogara kwenguva refu, zvishoma nezvishoma dzichigadzira kutenderera kwakanaka kwezvakatipoteredza.

Matambudziko neMhinduro

• Zvipingamupinyi ZvemariPakutanga, sangano remubatanidzwa rakasangana nematambudziko nekuda kwekushomeka kwemari, zvichiita kuti zviome kuisa mari yakawanda mumidziyo panguva imwe chete.

  Mhinduro: Mushandirapamwe uyu wakabatana nehurumende dzemunharaunda nemasangano asiri ehurumende (NGOs) kuti vawane rutsigiro rwemari uye nhungamiro yehunyanzvi, zvichibvumira kuitwa kwematanho akasiyana-siyana.

• Kuramba Kuchinja Pakati Pevarimi: Vamwe varimi vakanga vasina chokwadi nezvekurima zvirimwa zvisina makemikari uye matekinoroji matsva.

  Mhinduro: Minda yekuratidzira uye nyaya dzekubudirira zvakashandiswa kuwedzera chivimbo chevarimi nekutora chikamu, zvichikurudzira zvishoma nezvishoma kuchinja kubva pamabasa ekurima echinyakare.

Mhedziso

Kutarisira zvakanaka mwero weokisijeni yakanyungudutswa mumhando yemvura yekurima kwakakosha pakuvandudza kugadzirwa kwezvirimwa uye kuwana budiriro inoenderera mberi muPhilippines. Kuburikidza nematanho ekutarisa nekuvandudza, sangano rezvekurima rakabudirira kusimudzira mhando yemvura, richikurudzira kugadzirwa kwemupunga wemhando yepamusoro uye unobereka goho guru ukuwo richipa ruzivo rwakakosha rwemaitiro akafanana mune dzimwe nzvimbo. Mune ramangwana, sezvo kufambira mberi kwetekinoroji nemitemo zvichitsigira zvirongwa izvi, varimi vakawanda vachabatsirwa nemaitiro aya, zvichitungamira budiriro inoenderera mberi yekurima muPhilippines yese.
