Hei wāhanga māngai i roto i te mara otaputapu tēpu e pai ana mō te taiao, ko te whanaketanga o ngā taputapu kai e ahu mai ana i te witi ehara i te mea he tukanga hangarau noa iho engari he ao iti hoki o te whakaurunga āta haere owhanaketanga matomatongā ariā ki roto i ngā mahi ahumahi. I ngā tau 1990, me te tere haere o te ao ahuwhenua o tōku whenua,te whakaputa kakau witii tino piki ake, engari i tino kitea te raru o te whakakorenga kakau witi. Kāore i te whakapokea te taiao e te tahunga engari i whakararuraru rauemi anō hoki. I runga i tēnei horopaki, i puta puku mai ngā taputapu kai witi hei huarahi tūhura mō te whakamahinga rauemi o te kakau witi. I te tīmatanga, he iti noa ngā arai hangarau a te umanga, ko te nuinga i whakawhirinaki ki ngā awheawhe iti, whānau mō te hanga ā-ringa. He taketake noa te tukanga whakaputa, ā, ko ngā mea taketake noa iho pērā i ngā pereti me ngā peihana te kaha. He ngoikore te kaha o ngā hua me te ātete ki te wai, ā, he iti iho i te 1,000 tana te putanga. Nā te iti o ngā taumata hangarau me te mōhiotanga mākete, i whakamahia noa ēnei taputapu kai i ngā wāhi rangitahi pērā i ngā hakari ahuwhenua me ngā mahi mara. He iti te whānuitanga o te mākete, ā, ko te mōhiotanga o te marea ki ā rātouuara taiaoā, kāore i te rawaka te whaihua, ā, kāore anō kia tino tīmata te ahumahi o te whakamahinga o ngā rauemi kakau witi.

I te taenga mai ki te rautau 21, ka pā te ao whānui kite tiaki taiaoka ara ake te ngaru, ā, ka ara ake te mōhiotanga taiao ā-whare. I arohia whānuitia te raruraru o te parahanga mā i puta mai i ngā taputapu tēpu kirihou whakakorekore, ā, he whai wāhitanga nui tēnei mō te whanaketanga o te umanga taputapu tēpu witi. I taua wā anō, i whakauruhia e ngā whanaketanga o te pūtaiao rauemi me te hangarau hanga he kaha nui ki te tere o te ahumahi. Whai muri i te tau 2010, ko ngā tukanga matua pēnei ikakau witiI pakari te kuru me te whakamahine, te whakahāngai pāmahana teitei me te pēhanga teitei, me ngā paninga pirau-koiora. Ehara i te mea i whakatau noa i ngā āhuatanga mamae o te kore kaha, te ngāwari o te turuturu, me te ātete pāmahana ngoikore o ngā hua o mua, engari i taea ai hoki te whakawhānui i ngā kāwai hua. I whakaurua haeretia ngā hua i urutau ki ngā āhuatanga kai, pērā i ngā pouaka tina, ngā peihana hupa, me ngā kakau witi. Nā ngā whakapainga tukanga i tere ai te pikinga o te putanga, neke atu i te 1 miriona tana i te tau 2020, he pikinga neke atu i te mano ngā wā i whakaritea ki te tīmatanga o te rautau. I noho te tautoko kaupapa here hei "whakateretere" mō te whanaketanga ahumahi. I tino herea e te "aukati kirihou" ā-motu te whakamahinga o ngā taputapu tēpu kirihou kore-pirau ka taea te whakakore, ā, i whakauruhia e ngā rohe maha ngā kaupapa here tautoko, e whakarato ana i ngā whakahekenga taake me ngā tautoko R&D ki ngā kaihanga taputapu tēpu witi. I runga i tēnei horopaki,ngā taputapu kai i hangaia ki te witii angitu te noho hei huarahi whānui hei whakakapi i ngā taputapu tēpu whakakorekore, ā, i uru whānuitia ki ngā āhuatanga matua pērā i te kai i roto i ngā wharekai, te tuku kai, me te mekameka kai tere, ā, i tino piki ake te manakohia o te mākete.

I tēnei rā, ko tetaputapu tēpu kakau witiKua uru te umanga ki tētahi wāhanga whanaketanga pakari e tohuhia ana e te whakaputanga nui, te whakapūmautanga, me te ao whānui. Kei te whakapai tonu te pūnaha ahumahi, e hanga ana i tētahi tauira kohikohi me te tukatuka porowhita-kati o te "mahi tahi + kaimahi pāmu + hinonga." Ko ngā mahi tahi te kaiārahi i te whakaurunga o ngā rauemi kakau witi a ngā kaimahi pāmu, ko ngā umanga e whakarato ana i ngā aratohu hangarau me ngā taurangi hangarua. Mā tēnei ka whakatauhia te raruraru "maero whakamutunga" o te hangarua kakau witi, ā, ka whakaratohia he puna moni tāpiri ki ngā kaimahi pāmu. I ngā rohe whakaputa witi matua anake, kua whai hua tēnei ki te neke atu i te 100,000 ngā whare pāmu. He aunoa katoa te whakaputanga, ā, kua whakatūhia e ētahi umanga matua he pūnaha whakahaere kounga katoa mai i te whakamātautau rauemi mata me te tukatuka tukanga ki te tirotiro hua kua oti. Kua whiwhi ngā hua i ngā tiwhikete haumaru kai o te ao, ā, kua kaweake ki te 17 whenua me ngā rohe o te ao. Kei te haere tonu te whānui o te rahi o te mākete; e ai ki ngā raraunga ahumahi, e matapaetia ana ka eke te mākete taputapu kai kakau witi o te ao ki te US$86.5 miriona i te tau 2025, me te tere tipu ā-tau o te 14.9% i roto i ngā tau tekau e whai ake nei. Hei tāpiri atu ki tēnā, kei te tūhura tonu te umanga i ngā ara whanaketanga uara-nui tāpiri, me te whakatutuki i ngā putanga hou i roto i ngā wāhanga hou pēnei i te whakarerekētanga muka kakau witi me te whanaketanga opirau-orangā rauemi hiato, e whakawhānui ana i ngā hua ki te kai me te takai koha kounga teitei. Mai i tētahi hua para ahuwhenua kua warewarehia ki tētahi wāhanga matua e akiaki ana i te piriona tāramākete taiao, ko te whanaketanga o ngā taputapu kai mai i te kakau witi, ehara i te mea kua tutuki noa he painga pai mō te taha taiao me te taha ōhanga, engari kua whakaratohia hoki he tauira ahumahi ka taea te tāruarua mō te whakamahinga rauemi o ngā para ahuwhenua.
