Te wāhi o ngā tikanga hangarau āhuwhenua hou ki te whakapiki i te whaihua o te mahi me te whakamahi whenua

Kupu Whakataki

Kei te pākia te ahuwhenua o te ao e te pēhanga maha: te pikinga o te taupori, te huringa o te āhuarangi, me te pāngia o te whenua. Kia tae ki te tau 2050, e 97 piriona te taupori o te ao, ā, me piki te whakaputa kai mā te 70% kia ea ai ngā hiahia. I te wā kotahi, ko te huringa o te āhuarangi e whakaheke ana i ngā hua o ngā whenua whakaraerae mā te 30%, ā, kua ngaro te 33% o ngā oneone o te ao i te pāngia o te whenua. Ko te whakawhanaketanga o ngā tāone e pau ana i te 1.5 miriona heketea o ngā whenua ahuwhenua ia tau. Ko ngā kaiahuwhenua iti e whakaputa ana i te 80% o te kai o ngā whenua whakawhanake, engari ko rātou e pākia nuitia ana nā te rawakore. I tēnei horopaki, ka tirohia ngā hangarau ahuwhenua hou hei huarahi matua mō te whakawhanaketanga tauwhiro - te whakapiki hua me te whakaiti i te pānga ki te taiao, me te kore e whakawhānui i te whenua ahuwhenua.

Tirohanga Whānui o ngā Hangarau Ahuwhenua Hou

Kei roto i ngā hangarau ahuwhenua hou ngā momo mahi hou hei whakapiki i te whaihua, te tauwhirotanga, me te pakari. Ko te ahuwhenua tōtika e whakamahi ana i te GPS hei whakatere kūpapa, i ngā waka rererangi kore kaiurungi, me ngā whakaahua ā-rangi hei aro turuki i te ora o ngā tipu, te āhuatanga o te oneone, me te makuku. Mā te whakamahi hamuti me te patu whakamatū whakaheke i te nui, ka whakahekea te whakamahi tupurangi o te hamuti me ngā patu whakamatū mā te 40-60%, me te whakapiki hua mā te 20-30%. Ko te hangarau koiora, tae atu ki te whakawhiti ira me te CRISPR, kua whakaputa i ngā tipu e atete ana ki nga mate me te pēhanga āhuarangi. Hei tauira, ko te kāmioka Bt i Inia i whakaheke i te whakamahi patu whakamatū mā te 50% me te whakapiki hua. Ko ngā pūoko IoT me ngā pūnaha whakamakuku aunoa e aroturuki ana i te raraunga i te wā tonu hei whakapiki i te whaihua o te wai mā te 40-60%. Ko te aunoatanga me te hangarau karetao, pērā i ngā kaikokoti aunoa me ngā karetao whakateo tarutaru, e whakaiti ana i te kore kaimahi, ā, ka whakaheke i te utu whakaputa mā te 25%. Ko te ahuwhenua poutū e whakaputa ana i te kai i roto i te taiao whakahaere, ā, he 10-20 ngā whakareanga te nui o te hua i ia wāhi whenua ki te whenua ahuwhenua tawhito, me te whakaiti i te whakamahi wai mā te 95%. Ko te mātauranga horihori e whakamahi ana i te tātaritanga matakite, ā, neke atu i te 90% te tika o ngā matapae mō te pahūtanga o ngā mate me ngā ia hua, hei whakapiki i te kaha whakatau.

Ngā Pānga ki te Ahumahi

He hōhonu ngā pānga o ēnei hangarau ki te whaihua o te whakaputa ahuwhenua, ki ngā tikanga whakahaere pāmu, me te ao tukunga kai. Tuatahi, ka piki ake te whaihua: ko te ahuwhenua tōtika me te whakamakuku mārire e whakapiki ana i te hua mā te 20-30%, me te whakaiti i te moumou rawa, e whakaheke ana i te tapuwae taiao. Tuarua, ko ngā tikanga whakahaere pāmu e huri ana i te aronga mātau ki te aronga raraunga, ko te aunoatanga e whakaiti ana i te hiahia kaimahi, e whakarerekē ana i te hanganga kaimahi ahuwhenua, engari me whai pūkenga matihiko ngā kaiahuwhenua. Tuatoru, ko te ahuwhenua poutū me ngā pāmu tāone e whakapoto ana i te tawhiti mai i te māra ki te tepu, e whakapiki ana i te haumaru kai o ngā tāone, ā, ka taea te hanga anō i te ao tukunga kai. Tuawhā, ko ngā tipu hangarau koiora e whakapūmau ana i ngā hua, e whakaiti ana i te whakamahi patu whakamatū, e whakaiti ana i te tūpono o te toenga patu whakamatū i roto i te kai, engari ko te whakaaetanga a ngā kaihoko me ngā rerekētanga ture he wero tonu. Mai i te tirohanga haumi, ko te hangarau ahuwhenua e kukume ana i te nui o te pūtea, inarā i ngā wāhanga o te ahuwhenua tōtika me te pūtahi kapi.

Tirohanga ā-Mua## Ngā Tirohanga ā Muri Ake

I roto i ngā tau 3-5 e heke mai nei, ka tere te whanaketanga o ngā hangarau ahuwhenua ki te huarahi whakakotahi, māramatanga, me te toitū. Ko te whakakotahitanga hōhonu o te māramatanga horihori me te Ipurangi o ngā Mea e taea ai te whakahaere rawa tika ake, ā, ka āwhina ngā tauira matapae i ngā kaipāmu ki te whakahaere i ngā rerekētanga o te āhuarangi. Ko te hekenga o te utu o ngā mīhini aunoa e whai hua ai ngā pāmu iti me waenga. Ka piki haere te whakamahinga o te ahuwhenua poutū me ngā "whare tipu", inarā ki ngā rohe tāone kikī, utu nui te whenua. I te taha o te hangarau koiora, ko ngā tipu whakatika ira CRISPR ka whiwhi pea i te mana whakahaere ngāwari ake, e whakatairanga ai i ngā momo whakapakari e manawara ana ki te tauraki, te waipuke, me te kai totika. I tua atu, ko te whakamahinga o te hangarau poraka mekameka i roto i te whai take o te tukatuka kai ka whakapakari i te haumaru kai me te mārama o te tauhokohoko. Heoi, ko te whakapaunga moni tuatahi nui, te āputa matihiko, me ngā ārai whakahaere e tika ana kia whakatauria mā te tautoko kaupapa here, te mahi tahi tūmata-whānui, me te whakangungu kaipāmu. E matapaetia ana ā te tau 2030, ka whai wāhi matua ngā hangarau ahuwhenua hou ki te haumaru kai o te ao.

Kupu Whakakapi

Ko ngā hangarau ahuwhenua hou e whakarato ana i te rongoā whaihua mō te wero o te haumaru kai i raro i te tipuranga o te taupori me te rerekētanga o te āhuarangi. Mai i te ahuwhenua tika ki te māramatanga horihori, kua whakamatauria ēnei mahi hou e taea ai te whakapiki i te hua me te whakamahi whenua, i te whakaiti hoki i te kino o te taiao. Heoi, kia whakatutukihia te whakamahinga whānui me te tika, me whakatika ngā ārai pēnei i te utu, te mātauranga, me te whakahaere. Ko te mahi tahi a ngā kāwanatanga, ngā pakihi, me ngā tari rangahau e whakatau ai i te anamata o te ahuwhenua toitū.
