Kwinkqubela phambili ebalulekileyo yolawulo lwamanzi kwezolimo, ukusetyenziswa kwee-hydrological radar flowmeters kuvelise iziphumo ezithembisayo kuzo zonke iifama eMelika. Ezi zixhobo zintsha, ezisebenzisa itekhnoloji ye-radar ukulinganisa ukuhamba kwamanzi, ziye zavela njengezitshintshi zomdlalo kubalimi abazama ukuphucula ukusetyenziswa kwamanzi, ukuphucula isivuno sezityalo, kunye nokuhlangabezana nemingeni ebangelwa kukutshintsha kwemozulu.
Ixesha Elitsha Kulawulo Lonkcenkceshelo
Ngokwembali, ulawulo lwamanzi kwezolimo luxhomekeke kwiinkqubo zokulinganisa ukuhamba kwamanzi zemveli ezidla ngokungachanekanga kwaye zifuna umsebenzi omninzi. Nangona kunjalo, ii-hydrological radar flowmeters zibonelela ngendlela engangenisi manzi, echanekileyo kakhulu yokulinganisa ukuhamba kwamanzi ngexesha langempela kwiinkqubo zokunkcenkceshela. Ngokusebenzisa iteknoloji ye-microwave radar, ezi flowmeters zinokujonga ngokufanelekileyo ukusetyenziswa kwamanzi kwimibhobho, kwiitshaneli, nakwimisele ngaphandle kokufuna naluphi na utshintsho olubonakalayo kwiziseko zophuhliso ezikhoyo.
Iiprojekthi ezininzi zovavanyo kumazwe aphambili kwezolimo—eCalifornia, eTexas, naseNebraska—zibonakalise ukuba ezi zixhobo zinokubonelela abalimi ngedatha ebalulekileyo, nto leyo ebanceda ukuba benze izigqibo ezinolwazi malunga nokusetyenziswa kwamanzi. Olu buchule lubaluleke kakhulu kwixesha eliphawulwa ziimeko zembalela ezikhulayo kunye neenkxalabo malunga nokunqongophala kwamanzi.
Amabali empumelelo avela kulo lonke ilizwe
Abalimi abathatha inxaxheba kwiinkqubo zovavanyo baxele ukuphucuka okukhulu kwindlela yokulawula amanzi. KwiCentral Valley yaseCalifornia, ejongene neemeko ezinzima zembalela, abalimi abasebenzisa ii-hydrological radar flowmeters bafumene ukonyuka kwama-20% ekusebenzeni kakuhle kokunkcenkceshela. Ngokufumana idatha echanekileyo yokuhamba kwamanzi ngexesha langempela, aba balimi banokulungisa iishedyuli zabo zokunkcenkceshela ngokweemfuno zesityalo, banciphise inkunkuma yamanzi ngelixa bekhulisa impilo yesityalo.
ETexas, iqela labalimi bekotoni lisebenzise ii-radar flowmeters ukujonga ukusetyenziswa kwamanzi ngexesha lokukhula okuphezulu. Iziphumo zokuqala zibonisa ukuba abalimi banciphise ukusetyenziswa kwamanzi phantse nge-15-25% ngelixa begcina amanqanaba esivuno. “Ukuchaneka kwezi zibalo kusenza sikwazi ukuba neqhinga ngakumbi kwiindlela zethu zokunkcenkceshela. Kutshintshe indlela esicinga ngayo ngokusetyenziswa kwamanzi,” utshilo umlimi wasekuhlaleni uMiguel Rodriguez.
Ummandla waseMidwest nawo uyamkele le teknoloji, apho abalimi baseNebraska bexela iingenelo ezibalulekileyo. Ngokusetyenziswa kwe-radar flowmeters, ukusetyenziswa kwamanzi okuqhelekileyo ngexesha lokukhula okubalulekileyo kwehla, nto leyo esindisa izigidi zeelitha zamanzi kwiifama ezithatha inxaxheba.
Impembelelo kwiNdalo nakwiQoqosho
Iimpembelelo zokusingqongileyo zokuphucula iindlela zokunkcenkceshela nge-hydrological radar flowmeters zinzulu kakhulu. Iingcali ziqikelela ukuba ulawulo lwamanzi oluphuculweyo lunokunciphisa kakhulu ukuhamba kwamanzi kunye nongcoliseko lwezondlo oluhambelanayo oluchaphazela iindlela zamanzi kunye ne-ecosystems ezikufutshane.
Ngaphezu koko, iingenelo zoqoqosho kubalimi zinkulu kakhulu. Ngenxa yeendleko zamanzi eziphantsi kunye nesivuno sesivuno esiphucukileyo, imbuyekezo kutyalo-mali lwabanye abalimi ifunyenwe kwisithuba esingaphantsi konyaka. “Akukona nje ukonga amanzi; kukukonga imali nokuqinisekisa ukuba iifama zethu ziyaphila ixesha elide,” utshilo uLaura Thompson, ingcali yezolimo kwiSebe lezoLimo lase-United States (USDA).
Imingeni kunye namathemba exesha elizayo
Nangona kukho iziphumo ezintle, ukwamkelwa kwee-hydrological radar flowmeters kujongene nemingeni, kuquka iindleko zokuqala zokufakela kunye nomjikelo wokufunda ohambelana netekhnoloji entsha. Abanye abalimi bavakalisa ukuthandabuza ukutshintsha kwiindlela zemveli, kodwa abo benze utshintsho baxela ngokukhawuleza ukuba bayazibona iingenelo.
I-USDA kunye namasebe ezolimo karhulumente akhuthaza ngenkuthalo ukusetyenziswa kwee-radar flowmeters kwaye ahlola iindlela zokuxhasa ukufakwa kwazo kwiifama ezincinci. Njengoko ulwazi oluthe kratya lufumaneka, kulindeleke ukuba ukuxhasa ukwamkelwa ngokubanzi kuqine.
Isiphelo
Ukusetyenziswa kwee-hydrological radar flowmeters kuphawula ixesha elibalulekileyo ekufuneni iindlela zolimo ezizinzileyo eMelika. Njengoko abalimi bejongene nemingeni emibini yokwandisa isivuno sezityalo kunye nokugcina imithombo yamanzi, obu buchwepheshe butsha bunamandla okukhokela indlela eya kwikamva lezolimo elisebenza kakuhle nelinobuhlobo nokusingqongileyo. Intsebenziswano eqhubekayo phakathi kwabalimi, abaphandi, kunye nabaphuhlisi betekhnoloji iya kuba ngundoqo ekusebenziseni amandla apheleleyo olu phuhliso luthembisayo kulawulo lwamanzi ezolimo.
