He pūtake o ngā mahi auaha pūtaiao me te hangarau te umanga ahuwhenua. He rerekē rawa ngā pāmu hou me ērā atu mahi ahuwhenua i ērā o mua.
He maha ngā take e hiahia ana ngā tohunga o tēnei umanga ki te whakamahi i ngā hangarau hou. Ka taea e te hangarau te āwhina i ngā mahi kia pai ake, kia taea ai e ngā kaimahi pāmu te mahi i te nui ake i roto i te wā poto.
I te tipu haere o te taupori, ka piki haere tonu te hanga kai, ā, ko ēnei katoa e whakawhirinaki ana ki ngā maniua matū.
Ko te whāinga matua kia whakawhāitihia e ngā kaimahi pāmu te nui o te tongi e whakamahia ana e rātou, me te whakanui hoki i ngā hua.
Kia maumahara ko ētahi tipu e hiahia ana ki te nui ake o te tongi, pērā i te witi.
Ko te tongi he matū e tāpirihia ana ki te oneone hei whakaoho i te tipu o ngā tipu, ā, kua noho hei wāhanga nui o te mahi ahuwhenua, inā koa i te wā o te ahumahi. He maha ngā momo tongi, tae atu ki ngā tongi kohuke, ngā tongi rauropi me ngā tongi ahumahi. Ko te nuinga o ēnei he toru ngā matūkai nui: te hauota, te whākawa me te pāhare pāporo.
Engari, kāore te hauota katoa e tae atu ki ngā hua. Inaa, e 50% noa iho o te hauota i roto i ngā maniua ka whakamahia e ngā tipu i runga i te whenua pāmu.
He raruraru taiao te ngaronga o te hauota, nā te mea ka uru ki te āhuarangi me ngā wai pērā i ngā roto, ngā awa, ngā manga me ngā moana nui. He mea nui anō hoki kia mōhiotia ko ngā maniua hauota te mea e whakamahia whānuitia ana i roto i ngā mahi ahuwhenua o ēnei rā.
Ka taea e ētahi moroiti i roto i te oneone te huri i te hauota ki ētahi atu hau kei roto te hauota e kiia nei ko ngā hau kati kōtuhi (GHG). Mā te pikinga ake o ngā taumata o ngā tukunga hau kati kōtuhi ki te āhuarangi ka hua ake te mahana o te ao, ā, i te mutunga, te huringa āhuarangi. Hei tāpiri, he nui ake te whai hua o te hauota waikura (he hau kati kōtuhi) i te hauhā waro.
Ka pā kino pea ēnei āhuatanga katoa ki te taiao. He hoari mata rua ngā tongi kei roto te hauota: he mea nui mō te tipu o ngā tipu, engari ka taea te tuku i te hauota nui ki te rangi, ā, ka pā kino ki te oranga o te tangata me te kararehe.
I te mea ka nui haere ngā kaihoko e whakamahi ana i ngā momo noho matomato, kei te titiro ngā kamupene puta noa i ngā ahumahi katoa ki te whakamahi i ngā tikanga tauwhiro ake hei whakaputa pānga pai ki te taiao.
Ka taea e ngā kaimahi pāmu te whakaiti i te nui o ngā maniua matū e whakamahia ana mō te whakaputa hua, me te kore e pā ki te hua.
Ka taea e ngā kaiwhakatipu te whakarerekē i ā rātou tikanga whakamomona i runga i ngā hiahia motuhake o ā rātou hua me ngā hua e hiahia ana rātou kia tutuki.
