Poyang'anizana ndi kusintha kwa nyengo, kusowa kwa madzi, ndi kukwera mtengo kwa ndalama, alimi a ku United States ndi akatswiri a zachuma akuwunikanso momwe amasamalirira madzi. USDA's National Agricultural Statistics Service (NASS) yatulutsa Survey yake ya Irrigation and Water Management Survey ya 2023, yomwe ikuwonetsa zofunikira pakugwiritsa ntchito madzi, kutengera ukadaulo, komanso kukonza bwino m'mafamu aku America.
Kuchepa kwa Irrigated Acreage ndi Kugwiritsa Ntchito Madzi
Mu 2023, kafukufukuyu adapeza minda 212,714 yokhala ndi maekala othirira 53.1 miliyoni ku US, kutsika kuchokera kuminda 231,474 yokhala ndi maekala othirira 55.9 miliyoni mu 2018. maekala amadzi mu 2.8, poyerekeza ndi maekala 81 miliyoni mu 2023. Madzi ambiri omwe amagwiritsidwa ntchito pa ekala amakhalabe pa 83.4 acre-feet, kusonyeza kuti ngakhale malo omwe amathirira achepa, madzi akuyenda bwino pa ekala.
Kusintha kumeneku kumachitika makamaka chifukwa cha alimi omwe amazolowera chilala chomwe chatenga nthawi yayitali, makamaka kumadzulo kwa US, komwe kusowa kwa madzi kwasokoneza kwambiri ulimi. Njira zikuphatikizapo kuchepetsa kuchuluka kwa nthaka yothirira komanso kugwiritsa ntchito njira zamakono zothirira kuti ziwonjezeke ndi madzi ochepa.
Deta Yachigawo ndi Zokolola Zapadera
Mayiko asanu - Arkansas, California, Idaho, Nebraska, ndi Texas - akuyimira pafupifupi theka la maekala amthirira ku US ndipo amawerengera theka la madzi onse omwe amagwiritsidwa ntchito. Mayikowa ali ndi ntchito zazikulu zambewu, mbewu zamafuta, masamba, ndi udzu, zomwe zimadalira kwambiri madzi kuti zikwaniritse zosowa. Makamaka, California ndi Idaho zikupitilizabe kukumana ndi chilala, zomwe zapangitsa kuti boma likhazikitse mfundo zolimbikitsa kuteteza madzi paulimi.
Pankhani ya mtundu wa mbewu, gawo lalikulu kwambiri la ulimi wothirira limaperekedwa kwa mbewu zomwe zimagwiritsidwa ntchito ngati mbewu, mbewu zamafuta, masamba, ndi mbewu za nazale. Alimi adathirira maekala 49.6 miliyoni okolola poyera mu 2023, kutsimikizira kufunikira kwa mbewuzi m'zakudya zaku US.
Pitani ku Advanced Irrigation Technology
Chimodzi mwazofunikira kwambiri pa kafukufuku wa 2023 ndi kukwera kwa ulimi wothirira wothirira pa ulimi wothirira wachikhalidwe, pomwe maekala ena 12.6 miliyoni amathiriridwa ndi othirira. Kusinthaku kukuwonetsa kusuntha kwamakampani kutsata njira zogwiritsira ntchito bwino madzi. Machitidwe opopera, kuphatikizapo kuthirira kwapakati-pivot ndi drip, amapereka ulamuliro wabwino pa kugawa madzi ndipo akhoza kuchepetsa kuthamanga, phindu lofunika kwambiri m'madera ouma kumene dontho lililonse limawerengera.
Deta imasonyezanso kuti madzi apansi, opangidwa kuchokera ku zitsime zapafamu, amakhalabe gwero lalikulu la madzi amthirira, omwe amawerengera 54% ya madzi onse omwe amagwiritsidwa ntchito. Kuzama kwa chitsime tsopano ndi mamita 241, kutsindika kufunikira kwa zitsime zakuya pamene madzi apansi akuchepa m'madera ambiri aulimi.
Investment in Irrigation Infrastructure and Technology
Mu 2023, alimi adawononga pafupifupi $3 biliyoni pazida zothirira, kukonza malo, ndi matekinoloje apamwamba, ndi $ 3.3 biliyoni yowonjezereka kupita kumitengo yamagetsi popopa madzi. Mulingo uwu wandalama ukuwonetsa kufunikira kokulirapo kwaukadaulo mu ulimi wothirira. Kuchokera ku ulimi wothirira wodzichitira okha womwe umachepetsa kuwononga madzi kupita kuukadaulo wapamwamba wapakompyuta womwe umayang'anira chinyezi m'nthaka, zida izi zimathandiza alimi kukhathamiritsa kugwiritsa ntchito madzi, kusunga mphamvu, ndi kuchulukitsa zokolola ngakhale kuti chilengedwe chimakhala chovuta.
Kulima Mthirira Kukula
Horticulture pansi pa chitetezo-monga greenhouses ndi malo olamulidwa-idawonanso kukula, ndi 1.7 biliyoni mamita lalikulu pansi pa ulimi wothirira mu 2023, poyerekeza ndi 1.5 biliyoni mamita lalikulu mu 2018. kukhetsa madzi ndipo kumapereka mphamvu zoyendetsera ulimi wothirira. Kulima masamba otseguka kumunda kudakulanso, kuphimba maekala 598,980, kuchokera ku maekala 581,936 mu 2018.
Kafukufuku wa Irrigation and Water Management wa 2023 amapereka chidziwitso chofunikira kwa alimi, opanga mfundo, ndi mabizinesi aulimi. Detayi ikuwonetsa ntchito yofunika kwambiri yaukadaulo wothirira wotsogola komanso njira zoyendetsera bwino zamadzi poyankha kusowa kwa madzi komanso kupsinjika kwanyengo. Poikapo ndalama m'machitidwe atsopano, kuchepetsa maekala othirira, ndikuyika patsogolo njira zabwino kwambiri monga kuthirira ndi kuthirira, alimi aku US akuchitapo kanthu kuti madzi azigwiritsa ntchito bwino paulimi. Njirazi zidzakhala zofunikira posunga zokolola ndi kuteteza madzi m'zaka zikubwerazi.
