I-Brazil, izwe elaziwa ngezimo zalo zezulu ezihlukene kanye nokuhluka okuphawulekayo kwesizini, ikakhulukazi ihlangabezana nomehluko omkhulu phakathi kwezinkathi zayo zemvula nezomiso. Lokhu kuhlukahluka kwenza kube nesidingo sezinhlelo ezisebenzayo zokuqapha imvula ukuze kulawuleke imithombo yamanzi ayigugu yezwe ngendlela efanele. Elinye lamathuluzi abalulekile ekufezeni lokhu igeji yemvula, edlala indima ebalulekile ezinhlelweni ezehlukene, okuhlanganisa ukulawulwa kwezikhukhula zasemadolobheni, ukuphathwa kwamanzi ezolimo, nokuvikelwa kwemvelo.
1. Ukulawulwa kwezikhukhula zasemadolobheni
Emadolobheni ase-Brazilian, imvula enamandla ngesikhathi semvula ingaholela ezikhukhuleni ezinamandla, ezibangele ukulimala kwengqalasizinda futhi kube nezingozi ekuphepheni komphakathi. Ukusatshalaliswa kwamageji emvula kuzo zonke izindawo zasemadolobheni kufakazele ukuthi kunesandla ekulawuleni izikhukhula. Ngokuhlinzeka ngedatha enembile nefika ngesikhathi mayelana namandla emvula nokunqwabelana, iziphathimandla zendawo zingakha amasu asebenzayo okubhekana nezikhukhula.
Ngokwesibonelo, emadolobheni afana ne-São Paulo ne-Rio de Janeiro, idatha yesikhathi sangempela evela ezilinganisweni zemvula ivumela abahleli bedolobha ukuthi badizayine futhi bakhe amasistimu okukhipha amanzi asebenza kahle ahambisana nezici eziyingqayizivele zendawo yabo. Le ndlela yokuthatha isinyathelo ngokushesha ayigcini nje ngokudambisa imithelela yezikhukhula kodwa futhi ithuthukisa ukuphepha komphakathi futhi inciphise ukulahlekelwa kwezomnotho okuhlobene nezinhlekelele ezihlobene namanzi.
2. Ukuphathwa Kwamanzi Ezolimo
Ezolimo ziyisisekelo somnotho wase-Brazil, futhi ikhono lokuphatha izinsiza zamanzi ngempumelelo libalulekile kubalimi. Izikali zemvula zinikeza idatha ebalulekile esiza abalimi ukwenza izinqumo ezinolwazi mayelana nokutshala nokuvuna izitshalo. Ngokuqapha amaphethini emvula, abalimi bangaqonda kangcono ukuthi kufanele batshale nini, baqinisekise izimo zokukhula ezifanele futhi bakhulise isivuno.
Isibonelo, ngenkathi eyomile, abalimi bangasebenzisa idatha yegeji yemvula ukuhlela ukuchelela ngendlela ephumelelayo, ukonga amanzi kanye nokuqinisekisa ukuthi izitshalo zithola umswakama owanele. Lokhu kulawulwa kwamanzi okunembayo kuholela ekulahlekeni kwezilimo ezincishisiwe kanye nokukhiqiza okuthuthukisiwe, okuthuthukisa ukutholakala kokudla ezweni.
3. Ukuvikelwa Kwemvelo
Ihlathi lemvula lase-Amazon, elivame ukubizwa ngokuthi “amaphaphu Omhlaba,” libhekene nezinselele eziningi zemvelo, ezihlanganisa ukugawulwa kwamahlathi nokushintsha kwesimo sezulu. Amageji emvula abalulekile ekuqapheni amaphethini emvula nokuqonda imiphumela yawo kulesi simiso sezinto eziphilayo esibucayi. Le datha ibaluleke kakhulu kubacwaningi nezazi zemvelo ezisebenzela ukuvikela i-Amazon, njengoba isiza ukulandelela izinguquko emvuleni ezingaba nomthelela ezinhlobonhlobo zemvelo nempilo yamahlathi.
Ngokugcina inethiwekhi yamageji emvula esifundeni sase-Amazon, ososayensi bangahlaziya ukuthi izinguquko emvuleni ziwathonya kanjani amazinga amanzi emifuleni nasemifudlaneni, kanye nempilo yonke yehlathi lemvula. Lolu lwazi lubalulekile ekuthuthukiseni amasu nezinqubomgomo zokulondoloza okuhloswe ngazo ukulondoloza amagugu emvelo anothile ase-Brazil.
Isiphetho
Ukusetshenziswa ngempumelelo kwamageji emvula e-Brazil kuveze izinzuzo ezibalulekile emikhakheni eyahlukene. Ezindaweni zasemadolobheni, basiza ekulawuleni izikhukhula nasekuhleleni ingqalasizinda, okunomthelela ekuphepheni komphakathi nasekuqiniseni umnotho. Kwezolimo, basekela ukuphathwa kahle kwemithombo yamanzi, okuholela ekuvunweni kwezilimo ezithuthukisiwe kanye nokusimama. Ngaphezu kwalokho, amageji emvula anendima ebalulekile ocwaningweni lwemvelo nasemizamweni yokongiwa kwemvelo, eqinisekisa ukuvikeleka kwesimiso semvelo esibalulekile njengehlathi lemvula lase-Amazon.
Njengoba iBrazil iqhubeka nokubhekana nokushintshashintsha kwesimo sezulu kanye nezinselelo zemvelo, indima yamageji emvula izobaluleka kakhulu. Ukutshala izimali kubuchwepheshe obuphambili bokuqapha imvula kanye nokwandisa ukusetshenziswa kwazo ezweni lonke kuzobaluleka ekukhuthazeni intuthuko esimeme kanye nokuqinisekisa ukusetshenziswa kahle kwemithombo yamanzi eminyakeni ezayo.
