E ai ki ngā tatauranga, i te tau 2020, ka eke te maha o ngā kau miraka ki te 5.73 miriona i Haina, ā, ka eke te maha o ngā pāmu kau miraka ki te 24,200, ko te nuinga kei ngā rohe tonga-mā-uru, raki-mā-uru me te raki-mā-rāwhiti.

I ngā tau tata nei, kua maha ngā wā i puta ai ngā aituā "miraka paitini". Nō nā tata nei, kua tāpirihia e tētahi waitohu miraka ngā tāpiringa ture kore, ā, kua puta he ngaru o ngā kaihoko ki te whakahoki mai i ngā hua. Nā te haumaru o ngā hua miraka i whakaaro hohonu ai te tangata. Nō nā tata nei, i tū he hui a te China Center for Animal Disease Control and Prevention hei whakarāpopoto i te hanganga o ngā pūnaha tautuhi kararehe me te whai i ngā hua kararehe. I tohu te hui he mea tika kia whakapakari ake i te whakahaere i te tautuhi kararehe kia pai ai te kohikohi me te whakamahi i ngā mōhiohio whai i ngā hua kararehe.

I te whanaketanga o te pūtaiao me te hangarau me ngā hiahia mō te haumaru whakaputa, kua uru mārire te hangarau RFID ki te tirohanga a te tangata, ā, i te wa ano, kua whakatairangahia te whanaketanga o te whakahaere ahuwhenua kararehe ki te ahunga o te mamati.

Ko te whakamahinga o te hangarau RFID i roto i te mahi ahuwhenua kararehe, ko te nuinga o te wā, mā te whakakotahi i ngā tohu taringa (tohu hiko) kua whakatōkia ki roto i ngā kararehe me ngā kaikohi raraunga me te hangarau RFID auau-iti. Ko ngā tohu taringa kua whakatōkia ki roto i ngā kararehe ka tuhi i ngā mōhiohio o ia momo kararehe, whānautanga, werohanga, me ētahi atu, ā, he mahi tūnga anō hoki. Ka taea e te kaikohi raraunga RFID auau-iti te pānui i ngā mōhiohio kararehe i roto i te wā tika, tere, tika, me te puranga, ā, ka tere te whakaoti i te mahi kohikohi, kia taea ai te hopu i te tukanga whakatipu katoa i te wā tonu, me te whakamana i te kounga me te haumaru o ngā kararehe.

Mā te whakamahi noa i ngā tuhinga pepa ā-ringa, kāore e taea te whakahaere i te tukanga whakatipu mā te ringa kotahi, he whakahaere atamai, ā, ka taea te tirotiro mārama i ngā raraunga katoa o te tukanga whakatipu, kia taea ai e ngā kaihoko te whai i ngā tohu me te noho pono me te marino.

Ahakoa mai i te tirohanga a ngā kaihoko, mai i te tirohanga a ngā kaiwhakahaere ahuwhenua kararehe rānei, ka whakapai ake te hangarau RFID i te whai huatanga o te whakahaere, ka whakaata i te tukanga whakatipu, ā, ka nui ake te mohio o te whakahaere, koinei hoki te ia o te whanaketanga ahuwhenua kararehe ā muri ake nei.
