b. Te kaha hanga kiriata: Ka taea e ngā māngaro māngaro te hanga kiriata hei āwhina i te piripiri kia piri ki te mata, hei whakakaha hoki i te rauemi piripiri.
C. Whakamātotoru: He mea whakamātotoru i roto i ngā hanganga piri, e pā ana ki te matotoru me te whakapai ake i ngā āhuatanga tono.
d. Te pirau o te koiora: I ahu mai ngā māngaro ether i ngā rauemi hou, nō reira he pai mō te taiao, ā, he pai hoki mō ngā tono e aro ana ki te oranga tonutanga.
3. Ngā whakamahinga piri o te māngaro etera:
Ka taea te whakamahi i ngā etera māngaro i roto i ngā momo whakatakotoranga piripiri, pēnei i:
A. Ngā piripiri pepa me ngā takai: E whakamahia whānuitia ana ngā etera māngaro i roto i ngā piripiri pepa me ngā takai nā te mea he āhua hanga kiriata me te piri hoki ō rātou.
b. Ngā piripiri hanga: Nā te wairewatanga o te māngaro ether me tōna kaha ki te whakamātotoru, he mea pai hei whakamahi hei piripiri hanga hei āwhina i te here i ngā rauemi hanga.
C. Ngā Piripiri Rakau: I roto i te umanga mahi rakau, ka whakamahia ngā etera māngaro ki ngā piripiri rakau hei whakapakari i te kaha o te hononga me te pumau.
d. Ngā piripiri kakahu: Ka whakamahia te māngaro ether ki ngā piripiri kakahu nā te mea he kaha ki te hono i ngā muka me te whakanui ake i te kaha whānui o te kakahu.
4. Te mahi i roto i te taiao pāmahana teitei:
Mō ngā tono e pāngia ana e ngā pāmahana teitei, he mea nui te whakaaro ki te mahi a ngā etera māngaro i roto i ngā taiao pāmahana teitei. He maha ngā āhuatanga e pā ana ki tōna whanonga i tēnei take:
A. Te Pūmautanga o te Wera: He rerekē ngā taumata o te pumautanga o te wera o ngā māngaro ether i runga i te taumata o te whakakapinga me ngā whakarerekētanga matū motuhake i whakamahia i te wā o te tukanga whakaether.
b. Te pāmahana whakakākano: Ko te pāmahana whakakākano o te māngaro etera he tawhā matua i roto i ngā tono pāmahana teitei, ā, ka pāngia e tōna taumaha ngota me te taumata o te whakakapinga.
C. Ngā Huringa Matatini: Tērā pea ka huri te matatini o ngā hanganga piri kei roto ngā etera māngaro i ngā pāmahana teitei. He mea nui te mārama ki ēnei huringa kia mau tonu ai te mahi piri.
d. Kaha o te Here: Tērā pea ka pāngia te kaha o te here o ngā hanganga kei roto ngā etera māngaro e te pāmahana, nō reira me mārama pai ki ngā whakaritenga tono motuhake.
5. Rautaki whakarerekētanga mō te pumau o te pāmahana tiketike:
Hei whakarei ake i te whakamahinga o te māngaro ether i roto i ngā taiao pāmahana teitei, ka taea te whakamahi i ngā rautaki whakarerekētanga e whai ake nei:
A. Hononga-whakawhiti: Mā ngā ngota māngaro etera hono-whakawhiti ka piki ake te pumau o te wera me te ātete ki ngā huringa matotoru i puta mai i te pāmahana.
b. Te whakaranu ki ngā pūmua ātete-wera: Mā te whakakotahi i ngā etera māngaro me ngā pūmua ātete-wera ka taea te hanga i ngā hanganga piri ranu e pupuri ana i te pumau i ngā pāmahana teitei.
C. Ngā whakarerekētanga matū: Ka taea te tūhura i ētahi atu whakarerekētanga matū, pērā i te whakaurunga o ngā rōpū mahi ātete-wera, hei whakarite i ngā etera māngaro mō ngā tono pāmahana teitei motuhake.
6. Ngā rangahau take me ngā tono mahi:
Mā te tirotiro i ngā rangahau take o te ao tūturu me ngā tono mahi ka puta he māramatanga nui ki te mahi a ngā etera māngaro i roto i ngā taiao pāmahana teitei. Ka taea e ngā ahumahi e tino hiahiatia ana te ātete pāmahana, pērā i te motuka, te rererangi me te hikohiko, te whakarato i ngā tauira nui.
7. Ngā whakaaro mō te taiao:
I te mea ka nui haere te hiranga o ngā āwangawanga mō te taiao, ka tāpirihia he painga nui e te pirau koiora o ngā etera māngaro. Te aromatawai i te pānga taiao o ngā hanganga piri kei roto ngā etera māngaro i roto i ngā tono pāmahana teitei mō ngā mahi pumau.
8. Ngā huarahi me ngā whai wāhitanga rangahau ā muri ake nei:
Mā te rangahau me te whanaketanga tonu i roto i te mara o te whakarerekētanga māngaro etera ka taea te whakatuwhera i ngā huarahi hou mō tōna whakamahinga i roto i ngā taiao pāmahana teitei. He mea tika kia rangahaua te tūhura i ngā tikanga whakarerekētanga hou, te mārama ki ngā tikanga matua o te pumau wera, me te tautuhi i ngā mahi tahi me ētahi atu pūmua.
9. Whakamutunga:
Hei whakarāpopototanga, he pai ngā etera māngaro mō ngā tono whakapiri, he maha ngā āhuatanga e hiahiatia ana. Ko tōna mahi i roto i ngā taiao pāmahana teitei e whakawhirinaki ana ki te whakaaroaro tupato ki ngā āhuatanga pēnei i te pumau o te wera, te pāmahana whakapūmau me te kaha o te here. Mā roto i ngā whakarerekētanga rautaki me ngā hanganga auaha, ka taea te whakarite i ngā etera māngaro hei aro atu ki ngā wero motuhake e pā ana ki ngā pāmahana teitei, ka whakatuwhera i ngā huarahi hou mō te whakamahinga i roto i ngā ahumahi he mea nui te ātete ki te wera. I te haere tonu o ngā rangahau, tera pea ka whānui ake te tūranga o ngā etera māngaro i roto i ngā tono whakapiri, ka whakapūmau ake i tō rātou tūranga hei kai whakapiri maha-whakamahinga me te pumau.
