Tichitarisana nekushanduka kwemamiriro ekunze, kushomeka kwemvura, uye kukwira kwemitengo, varimi vekuUS nenyanzvi dzezvekurima vari kuongororazve mashandisiro avanoita zviwanikwa zvemvura. Iyo USDA's National Agricultural Statistics Service (NASS) yakaburitsa ongororo yayo ye2023 Irrigation and Water Management Survey, iyo inoratidza maitiro akakosha mukushandiswa kwemvura, kutora tekinoroji, uye kuvandudzwa kwemapurazi ekuAmerica.
Kuderera kweIrigated Acreage uye Kushandiswa Kwemvura
Muna 2023, ongororo yakaitwa yakaratidza kuti mapurazi 212,714 53.1 ane mahekita 231,474 miriyoni akadiridzwa muUS, kuderera kubva pa55.9 mapurazi ane 2018 miriyoni maeka ekudiridza muna 2.8. Kudzikiswa kwemaeka ekudiridza kunoenderana nekudonha kwe81% pakushandisa mvura mumapurazi e2023 miriyoni. maeka-tsoka emvura muna 83.4, zvichienzaniswa ne2018 miriyoni acre-feet muna 1.5. Avhareji yemvura inoshandiswa paeka inoramba iri paXNUMX acre-feet, zvichiratidza kuti kunyange zvazvo nzvimbo iri kudiridzwa yadzikira, paeka imwe yemvura yakaramba yakamira.
Shanduko idzi dzakanyanya kukonzerwa nevarimi vanojairana nekusanaya kwemvura kwenguva refu, kunyanya kumadokero kweUS, uko kushomeka kwemvura kwakanganisa zvakanyanya kurima. Matanho anosanganisira kuderedza kuwanda kwevhu rinodiridzwa uye kushandisa michina yemadiridziro inobudirira kuitira kuti goho riwedzere nekuwanda nemvura shoma.
Dunhu uye Crop-Yakananga Data
Nyika shanu — Arkansas, California, Idaho, Nebraska, neTexas — dzinomiririra inenge hafu yemaeka akadiridzwa muUS uye inoita inopfuura hafu yemvura yese inoshandiswa. Idzi nyika ndidzo mashandiro akakura muzviyo, mbeu yemafuta, muriwo, uye zvirimwa zveuswa, izvo zvinovimba zvakanyanya nemvura kuti zvizadzise zvinodiwa. Sezvineiwo, California neIdaho dzinoramba dzichitarisana nekumanikidzwa kubva mukusanaya kwemvura, izvo zvatungamira kune mitemo yenyika inokurudzira kuchengetedzwa kwemvura mukurima.
Panyaya yemhando yechirimwa, chikamu chikuru cheminda yekudiridza yakatsaurirwa kune zvirimwa zvinoshandiswa zviyo, mbeu dzemafuta, miriwo, uye zvirimwa zvemukoti. Varimi vakadiridza mahekita 49.6 miriyoni eminda yakakohwewa pachena muna 2023, zvichisimbisa kukosha kwezvirimwa izvi muhurongwa hwekudya hweUS.
Chinja kuenda kuAdvanced Irrigation Technology
Chimwe chezvakanyanya kuwanikwa kubva muongororo ya2023 kukwira kwemadiridziro emwaya pamusoro pemadiridziro echinyakare anokwevera pasi, nemaeka 12.6 miriyoni akawanda akadiridzwa nevanomwaya mvura. Kuchinja uku kunoratidza kufamba-famba kweindasitiri kune nzira dzekushandisa mvura dzinoshanda. Masisitimu esprinkler, anosanganisira pakati-pivot uye kudiridza kwekudonha, anopa kudzora kurinani pamusoro pekugovera mvura uye anogona kuderedza kuyerera, bhenefiti yakakosha munzvimbo dzakaoma umo donhwe rega rega.
Iyo data inoratidzawo kuti mvura yepasi, inotorwa kubva pamatsime epapurazi, inoramba iri iyo huru yekudiridza, inoverengera 54% yemvura yose inoshandiswa. Ivhareji yemvura yakadzika ikozvino 241 tsoka, kusimbisa kudiwa kuri kukura kwematsime akadzika sezvo mvura yepasi inoderera munzvimbo dzakawanda dzekurima.
Investment muIrrigation Infrastructure uye Technology
Muna 2023, varimi vakashandisa mari inosvika mabhiriyoni matatu emadhora pamidziyo yekudiridzira, kuvandudzwa kwevhu, uye matekinoroji epamusoro, neimwe mabhiriyoni matatu emadhora ichienda kumitengo yemagetsi pakupomba mvura. Iyi nhanho yekudyara inoratidza kukosha kuri kukura kwehunyanzvi hwekudiridza. Kubva kuzvigadziriso zvemadiridziro zvinoderedza marara emvura kusvika kuhunyanzvi hwemakombuta hwepamusoro hunotevera hunyoro hwevhu, maturusi aya anobatsira varimi kukwenenzvera mashandisirwo emvura, kuchengetedza simba, uye kuwedzera goho zvisinei nemamiriro ekunze.
Irigated Horticulture iri Kuwedzera
Horticulture pasi pedziviriro - senge muma greenhouses uye inodzorwa nharaunda - yakaonawo kukura, ine 1.7 bhiriyoni masikweya tsoka pasi pekudiridza muna 2023, zvichienzaniswa ne 1.5 bhiriyoni masikweya tsoka muna 2018. Kuwedzera uku kunoratidza maitiro akafara kune kurima kwakadzivirirwa, uko kunochengetedza mvura nekuganhura. evaporation uye inopa kudzora kurinani pane zvekudiridza. Open-field horticulture yakakura zvakare, ichifukidza 598,980 mahekita, kubva pa581,936 mahekita muna 2018.
Iyo 2023 Irrigation uye Water Management Survey inopa ruzivo rwakakosha kuvarimi, vanoita mitemo, uye mabhizinesi ekurima. Iyo data inosimbisa basa rakakosha reiyo tekinoroji yekudiridza uye maitiro ekutonga emvura anobudirira mukupindura kushomeka kwemvura uye kudzvanywa kwemamiriro ekunze. Nekudyara muhurongwa hutsva, kudzikisira acreage yekudiridza, uye kukoshesa nzira dzepamusoro-soro senge sprinkler uye drip irrigation, varimi vekuUS vari kutora matanho akasimba kuti vaone kushandiswa kwemvura kwakasimba mukurima. Aya mazano achave akakosha mukuchengetedza goho nekuchengetedza zviwanikwa zvemvura mumakore anotevera.
