    Tirohia ngā rautaki e ora tonu ai ngā arawai mō ērā kei te taha whakararo o te wai me ngā ika taketake, waihoki ka whaihua hoki ngā pāmu, e kore ai hoki e heke iho ngā putanga.

    He rite te pāmu kāore ōna kōawa ki te ika whai paihikara – me uaua ka kitea! Ahakoa kāore pea e pērā rawa te purata o te rauwiringa kōawa, manga hoki e rere ana i ngā pāmu, kāore e kore he ika taketake, he hātaretare, he rērēwai anō hoki kei roto i aua wai. Tērā pea he whaitua whakaputa hua ngā kōawa kei ngā pāmu kei te taha moana mō te terenga o te inanga i reira, tērā pea he kōwao onge kei ngā pāmu hipi kei ngā ika whenua.

    I kitea i ngā tatauranga kātahi anō ka puta, ko te 72% o ngā momo ika taketake e 39 – i whai wāhi ki te tatau – kua tata te korehāhā. Ko tētahi hautoru anō o ngā otaota taketake me ngā hātaretare e pērā ana anō hoki.

    Mā te whakarite kia marumaru ngā kōawa, kia kaua ai e takahia e te kararehe, e tauria e te parapara me te kenepuru, me te whakarite kia pai ngā kōrere mō ngā ika e ora pai ai ngā ika taketake i tō pāmu. Pērā i te pōpokotea a te kaikeri, he tohu pai ngā momo ika me ngā hātaretare kei tō pāmu i te ora o te wai me te pai o ngā mahi tiaki i te pāmu.

    Ako me pēhea e whai ora ai ngā arawai mō te hunga kei te taha whakararo o te wai me ngā ika taketake, e whai hua ai anō hoki tō pāmu me ōna kaupapa.

    Whakatōkia ngā wāhi tūpoupou

    Kaua e tukuna kia horo tō pāmu. Ma te whakatō otaota i ngā paritū, i ngā pakohu me ngā tahatika e iti iho ai te horo o te whenua i te pāmu, kia kore ai te kenepuru e tau ki roto i te wai. E kore e ora te maha o ngā ika taketake i te wai kua kī i te waipara.

    He huakore hoki ngā wāhi paritū i te pāmu. E mahia tonuhia ana ngā mahi e kitea ai me pēhea te aukati i ngā te horo o te whenua i ēnei wāhi, me te whakapiki i te hua ka puta i te whenua nei, pēnei Mānuka plantation research for medical grade honey.

    Āraia te pūkohu ngaruru

    Nā te wai ora, ko te kararehe ora. Ko te tikanga o tēnei kōrero, he aukati i te rere o ngā whakamōmona ki ngā arawai. Ka hora ngā pōkuhu ngaruru patu i te tangata, i te kurī me te kararehe i te nui rawa o ngā whakamōmona i te wairākau me te parapara; i te wera o te rangi me ngā kōawa kāore e whai marumaru. Aukatihia te pōkuhu ngaruru mā te whakatū taiapa, mā te whakatō otaota hoki ki ngā arawai hei whakamātao i te wai. Ki te kore e taea te whakatū taiapa, whakatūria he waka whāinu kararehe,whakatōkia hoki he rākau whakamarumaru ki te wāhanga o runga o te pātiki, kia kore ai ngā kararehe e whakatata atu ki ngā repo me ngā kōawa.

    Ko te whakapākeka whakamōmona tētahi raru nui mō te taiao. Tuatahi, ka nui rawa te pākawa ota ka uru ki ngā manawa ā-whenua e whakamahia ana hei wai ihu. He raru tērā nō te mea ka whakamahia tērā wai i ngā pātara miraka mā ngā pēpi, otirā tē taea e ngā tinana pēpi te pākawa ota te kūnatu pēnei i tō te pakeke. Nō reira, me rite te nui o te pākawa ota kei ngā wai inu ki tā te World Health Organisation i whakatau ai, arā, kei raro iho i te 10 mirikarāmu pākawa ota i te rīta kotahi.

    Tuarua, ko tētahi āhuatanga e kaka kitea ana i Aotearoa ināianei, ko te whakamōmona o ngā wai. He karangatanga tēnei mō te matomato o te tupu o ngā tarutaru me ngā pūkohu wai i ngā kōawa me ngā wahapū. Ko te take i tino pēnei ai te kino, ko te pākawa ota me te pūtūtaewhetū. Ka rere te pākawa ota i te pāmu nei ki tētahi roto, ki tētahi wahapū rānei. Ki te tae ngātahi me te pūtūtaewhetū, he tino whakamōmona tērā, ā, ka matomato te tupu mai o ngā tarutaru porearea me ngā pūkohu wai. Waihoki, he nui ngā hua kino ka taka iho mai i tēnei me ngā tūmomo whakamahinga i te wai mō ngā kaupapa ngahau, me te whaihua o ngā puni koiora, nō te mea ka patua ngā kararehe me ngā otaota kia mate.

    Ko te Takurua tētahi wāhanga o te tau e kino ai te whakapākeka o te pākawa ota. Tuatahi, koirā te wāhanga o te tau e tino heke ai te ua, ka kawea te pākawa ota kei te one e te wai. Tuarua, he wāhanga o te tau, kāore otaota e tino horomi ana. Mena e tino mārakerake ana te pātiki, he nui te pākawa ota e whakahokia ana ki taua pātiki hei mimi, engari kāore he otaota hei horomi i taua pākawa ota kia mahana rānō te whenua i te Koanga Nō reira, koirā ngā take nui e rua ko te Takurua te wāhanga o te tau e nui ai ngā matū ka whakapākekatia.

    Whakatōkia ngā repo

    He hikuwai whakahirahira ngā whenua pōharuharu me ngā wairepo rei e papī ai te wai me ngā puna i te pāmu mō ngā kōawa, waihoki ka tino whaihua i ngā marama maroke o te raumati. He pai hoki ēnei repo hei tātari i ngā whakamōmona i mua i te terenga ki ngā arawai. Kaua e tangohia te wai o reira, whakatūria kētia he taiapa, whakatōkia hoki ki ngā mauti māori, ngā toetoe me ngā harakeke hei whaitua kaupare hei ngongo, hei whakapōturi i te rara o te wai pātaua i muri i te patapataiāwhā.

    Tiakina ngā awakeri

    Kaua ō huamoni e riro i te keri manga. Mā te whakatū taiapa me te whakatō otaota ki rō manga e raru ai ngā taru i te maru, e aukati ai hoki i te kenepuru, kia iti oho ai ō keringa i aua manga. Ki te iti iho te whakatikatika, ka nui ake te wā me te pūtea ka penapenahia.

    Whakaitihia te hauota

    Kia māmā te tuku i te hauota. Ka puta mai te hauota i ngā parapara kararehe, i ngā whakamahinga wairākau rānei. Ki te nui ake te hauota i tā ngā otaota e āhei ai ki te horomi, ka rere te toenga ki ngā arawai. Waihoki, ka huri te hauota ki te hauota-rua ōkai (N20), he haurehu kati mahana ka whai wāhi ki te kati mahana (greenhouse effect), e piki ai te paemahana o te ao.

    He whakaritenga pai ā-pāmu te whakahaere i te hauota. Mā te whakatō i ngā otaota horomi hauota, mā te whakamahi i ngā utauta whakatahua whakamōmona e tutuki ai tēnā. Mā te waiho i ngā pīnaki e horo haere ana me ngā whenua pōharuharu e iti iho ai te hauota e whakapākeka ana ki ngā arawai. Pānuitia tēnei nutrient management mō te pāmu, whakamahia rānei tēnei e ako ai i ngā kōrero mō Terrestrial nitrogen cycle.

    Ka taunaki te pūrongo a te kāwanatanga Our Fresh Water i te whakaaro e piki haere ana te nui o ngā pākawa ota me te hauota kei ngā arawai.

    Ko tētahi whakaritenga whakahaere e whakaitingia ai te ngaro haere o te hauota, kia kaua e nui rawa te hauota ka whakamahia i ia whakamahinga, i te tau rānei. Ka whakapau kaha hoki mātou kia tika te whakahaere i ngā parapara kararehe ka kohikohia e mātou i ngā whare miraka kau, kia iti te whakahokinga ki te whenua. Mā te aukati i te haerenga o ngā kararehe ki te mimi ki ngā whaitua otaota apiapi e iti haere ai te ngaromanga o te mimi tata ki ngā kōawa.

    Ko tētahi atu rautaki, ko te āta whakaaro mō te wāhi e whakahokia ai te mimi kararehe. I ngā wāhi e taea ana, me whai wāhi ngā kararehe ki ngā marumaru, e pai ai te kohi i te mimi, kia purutia i te Takurua, ka whakahokia ai ki te whenua hei te Koanga e whai mai ana. Mā reira e iti rawa ai te nui o te hauota e whakapākeka ana.

    Ko tētahi atu rautaki whakahirahira hei āwhina ki te whakahaere i te raru hauota, ko te āta tiaki i ngā whaitua otaota apiapi me ngā repo. He wāhanga whakahirahira ngā repo o te taiao, ka noho hei wāhi tātari mō te para, inarā te tātari i te hauota e uru ana ki ngā repo. Nō reira, he mea nui te tiaki i ngā repo e toe tonu nei, te whakaara anō i ngā repo kua karia kētia, kua kaha te whakamahi hei whenua whāngai kararehe. Me kaua hoki e tuku i ngā kararehe kia kai i ngā whaitua otaota apiapi, nō te mea ka pākarukaru te whenua i ngā waewae kararehe, ka tiko ai, ka mimi tika atu ai ki ngā arawai.

    Kikī ana te mimi i te hauota, ā, kikī ana te tiko i te pūtūtaewhetū me ngā huakita tiko. Ka whakakaha ake te pūtūtaewhetū i te raru whakamōmona wai, ka kawea hoki e ngā para tiko ngā rauropi meroiti i ngā tūmomo māuiui e māuiui ai te tangata, nō reira me mātua kaupare tērā. Ko te rautaki matua, ko te whakatū taiapa.

    Ko te utauta Overseer tētahi tauira whakatahua whakamōmona, he mea whakawhanake e ētahi whare wānanga me ngā CRI. He utauta hei āwhina ki te ārahi i ngā whakahaeretanga whakamōmona, inarā ngā hua o te wairākau, kia kore ai e tāruahia te haumako o ngā para me ngā wairākau anō hoki. E kaha ana te whakamahia o taua utauta ki te whakatau, te pānga o te hauota ki te wai, ki te kōhauhau rānei i ngā mahi pāmu rerekē me ngā taiao, one, paemahana rerekē anō hoki. Ka tino whaihua tēnā utauta mō tātou ki te kimi huarahi e pai ai ngā kaipāmu ki te tirotiro ki ngā tahua pūtea me te kī ake “Ka pai, me pēhea au e whakapiki i te whāomotanga o ngā whakamōmona, me pēhea hoki au e whakaiti i ngā huakoretanga, me pēhea hoki au e tino whai hua ina hoko wairākau ahau?”

    Aukatia ngā kararehe ki te taiapa

    Ka pākarukaru ngā tapa koawa i ngā kararehe, ā, ka paru hoki te wai i te tiko me te mimi ka rere tika atu ki te wai. Ka piki te taumata o te hauota i tērā. Me pai ngā tahatika kōawa mō ngā ika taketake hei wāhi huna, hei wāhi whakaputa hua anō hoki; kāore hoki rātou e paku rata ki te waikōparu.

    Mō ngā kaipāmu, ehara te kukume kau i ngā repo me ngā arawai i ngā pō marangai o te Hōtoke i te mahi ngahau, ā, kāore hoki e whaihua ā-moni nei ina mate ngā kau, inā hoki ka ngaro tōna $1500 i ia kau tuku waiū pai ka mate.

    Huri noa i te motu, e kitea ana e ngā kaipāmu, mā ngā tikanga manaaki taiao whaihua, pērā i te whakatū taiapa i ngā arawai, ka angitu ā rātou pakihi, he whakaritenga pai ā-pāmu anō hoki.

    He kōrere pai mō ngā ika

    Me mātua wātea ngā arawai hei terenga mō ngā ika. Me whai wāhi ētahi ki te heke, e tutuki ai te huringa ā-oranga.

    Tirohia ngā kōrere kei te pāmu – tohua ngā whakawhitinga kōrer e whaihua ana, whakatikaina ērā kāore e whaihua ana. Whakatikahia ērā mā te tāpiri rōnaki, i ngā pāwhata anō hoki.

    Ina whakatūria ai ētahi kōrere hou, me pai mō ngā ika!

    Ko te raru o ngā kōrere kei ngā hikuawa, ka haukoti i te whaitua i te pū matua o te awa. He kōrere nui te kōrere, ka āwhina ki te tango i te wai i te whenua, engari ko te raru o ngā kōrere, ka whakatūria i runga ake i te wai, ka tata rānei ki te wai (kei te āhua o te awa te tikanga). Mō ngā inanga – pēnei i te kōkopu me ētahi atu – e āhei ana ki te piki, engari anō te peke. Ehara i te tipua!

    Ko ngā rōnaki ika me ngā pāwhata ētahi wāhanga e pīrangi nei mātou ki te āpiti atu ki ngā kōrere me ngā kēti waipuke e pai ake ai te tūhonotanga o te awa me te hikuawa, nō te mea e pai ana ki ngā kōkopu, ngā kōaro me ngā īnanga aua hikuawa. Kei reira pea aua ika e whakaputa hua ana, nō reira me māmā te whakawhitinga, engari me kaua e kino ki te whakamahinga o aua whenua nō te mea he mahi tā ngā kōrere. I te nuinga o te wā, ka hāngai ki te haumarutanga o te tangata, inarā ngā kēti waipuke. Kāore mātou i te hiahia kia uaua te nohotahi o te tangata me te taiao.

    Ko ngā rōnaki toka, ko ngā rōnaki ika he rautaki e tūhonotia anō ai ngā hikuawa whai ārai, pēnei i ngā kōrere me ngā kēti waipuke.

    Ko ngā rautaki kua whakamahia e NIWA, ko te whakamahi i ngā toka kua purua ki ngā rōnaki raima. He tau ngā ika ki te piki, arā ngā ika ririki, nō reira me whakarite huarahi e hipa ai rātou i ngā kōrere. He wāhi whakatā hoki ēnā mō ngā ika.

    Ko te pāwhata he toka, he pereki rānei kei roto i te kōrere, hei huarahi piki mō ngā ika, hei wāhi whakatā anō hoki.

    Ka rerekē rawa te awa i ngā kōrere nei. I te nuinga o te wā, ina heke ai ngā hikuawa nei, ka whkapōturihia te rere e ngā kōpikopiko o te awa me ngā awa. He arawai torotika noa ngā kōrere, nō reira ka tino tere te rere o te wai, ka kaha hoki te rere. Ki te purua he pāwhata ki reira, kua whai wāhi ngā ika ki te piki i te pīnakitanga o ngā kōrere rā, kua whai wāhi whakatā, haumaru hoki ina ngēngē ai.
