Indima Eshintshayo Yabaphathi Bedolobha Ezindaweni Eziluhlaza Ezisakhiweni

Amamenenja amadolobha aye aba yizici eziyinhloko ekushukunyisweni kokulondolozwa kwamadolobha, asebenza ngokuguqula izinhlelo zendawo ezungezile zibe nezibonakalayo, ezakhiweni ezisemhlabeni. Izakhiwo zemvelo nezemvelo — ulwembu lwezimiso zemvelo ezinikeza ukulawulwa kwamanzi anesiphepho, izinga lomoya, kanye nokuzinziswa kwesimo sezulu — kudinga izinga lokusebenza kwezindawo ezihambelanayo ezidingwa ezinye izinyathelo ezimbalwa zikamasipala. Ngokungafani nezakhiwo zemvelo ezimpunga, ezilandela imishini yobunjiniyela nezindlela zokuthola izakhiwo, imisebenzi eluhlaza ngokuvamile idinga abaphathi bedolobha ukuba bahambele indawo engekho ngokwezimali, izivumelwano zomphakathi, nokulungisa isikhathi eside.

Izidingo kubaphathi bedolobha ziye zakhula njengoba imiyalelo kahulumeni nombuso yokulawula amanzi esiphepho, ihlangene nokucindezela komphakathi kokuthatha isinyathelo sesimo sezulu, ukuphoqelela omasipala ukuba bathathe isinyathelo. Ngesikhathi esifanayo, ohulumeni bendawo babhekana nezindleko eziqinile zemali nezisebenzi ezilinganiselwe. Umphathi wedolobha ongaphumelela ekuhleleni uhlelo lwezakhiwo zezakhiwo eziluhlaza kumelwe abe yindawo ehlelekile, abe nengxenye ekuhleleni iziphene zemali, kanye nohlelo lomphakathi. Ukuqonda ukuthi lezi zinhlelo zingenziwa kanjani zisuka emhlabathini phezulu kubalulekile kunoma yimuphi umasipala olindele ukwakha impumelelo emashumini eminyaka ezayo.

Ukuhlela Okuhlelekile Ekuhleleni Ukuhlanganiswa Komhlaba Oluhlaza

Ukusetshenziswa kwezakhiwo eziluhlaza okuphumelelayo kuqala kudala ngaphambi kokuba noma iliphi ifosholo ligawulwe. Abaphathi bedolobha kumelwe basungule amapulani abanzi ahlanganisa imigomo eluhlaza nemisebenzi ephambili kamasipala engokomnotho, impilo yomphakathi, kanye nokuhamba. Ngaphandle kwalokhu, imisebenzi eluhlaza okotshani ibhekwa njengemifantu efakiweyo yezakhiwo zedolobha kunokuba ibhekwe njengeminyombo yezezimali eziyisisekelo.

Ukuqhuba Isikhungo Sesisekelo

Isinyathelo sokuqala kunoma iyiphi inqubo yokuhlela i-octractal ukuqonda isimo samanje sendawo ezungezile yasedolobheni. Abaphathi bedolobha kufanele bathumele ukuhlolwa okuphelele okuhlanganisa ukudweba izakhiwo zamanzi anesiphepho, ukuhlukanisa izindawo ezikhona, ukuhlola ukuhlanganisa izihlahla ezingaphezulu okungavikeleki, nokuhlola ukusakazeka kwezihlahla. Lokhu kunikeza ukwaziswa okudingekayo ukuze kubekwe izimali futhi kuboniswe ukubaluleka kwezakhiwo eziluhlaza zokukhetha izikhulu nomphakathi.

Ukuhlolwa kwe-Baseline kwembula namathuba okuthola i-coneflution. Ngokwesibonelo, indawo enamanani aphakeme esifuba somoya ingazuza ekutshaleni izihlahla ezithuthukisa izinga lomoya kuyilapho zilawula amanzi anesiphepho. Abaphathi bedolobha bangasebenzisa lokhu kuxhumana ukuze bakhe ukusekela okubanzi eminyangweni yezempilo, izinhlangano zokuhlela, namahhovisi emvelo.

Ukubeka Imigomo Elinganiswayo Nemisebenzi

Izibopho ze-"ukungaguquguquki" akuvamile ukusinda enqubweni yokuhlela imali. Abaphathi bedolobha kumelwe bachaze izisulu eziqondile, ezikwazi ukuchazwa ngokunembile, izinyathelo zezakhiwo eziluhlaza. Lokhu kungahlanganisa amalitha amanzi avuthulukileyo abanjwe ngonyaka, amahektare ezindawo ezivuleke ngaphandle, inani lezihlahla ezitshalwe, noma ukuncitshiswa kwezenzakalo zendle ezihlangene. Ukumiswa kwemigqa ecacile yezindawo kwenza abaphathi bedolobha baqhubekele phambili, bathethelele ukutshala izimali, futhi baxhumane nemiphumela yababambi bezindawo.

I- U.S. Environmental Protection Agency inikeza isiqondiso ezindleleni ezivamile nasemagabeni angazithatha emadolobheni. Ukuhlanganisa lezi zindlela nemigomo yedolobha ebanzi — njengokunciphisa imiphumela yesiqhingi eshisayo noma ukuthuthukisa izinga lamanzi ekutholeni izindikimba zamanzi — kuqinisa isimo sezezisekelo eziluhlaza njengomsebenzi wesizinda esiyinhloko kamasipala kunokuba kube uhlelo lwendawo ezungezile ezungezile.

Ukuthutha Ngezinhloso Zokuthuthukisa Inhloko - dolobha

Enye yamasu aphumelela kakhulu abaphathi bedolobha abangayisebenzisa yizisekelo eziqinile eziluhlaza ezisemqoka elungiselelweni lenhloko- dolobha lokuthuthukisa (CIP). Kunokuba ithathe imisebenzi eluhlaza njengezindlela zokuthatha i-asterene, kufanele iphothwe ifakwe emisebenzini yokwakha kabusha imigwaqo, ukulungiswa kwepaki, ukwakhiwa kwezakhiwo zomphakathi, nokubuyiselwa kwesimiso somphakathi. Lokhu kunciphisa kakhulu izindleko ngoba izakhi eziluhlaza zikhona phakathi nomsebenzi wokwakha osezishisiwe.

Ngokwesibonelo, uma umgwaqo uhlelelwe ukuvuselelwa, umphathi wedolobha angaqinisekisa ukuthi umklamo uhlanganisa ukunqanda ukunwetshwa kwezingadi zemvula noma izingxenye zomgwaqo ezikwazi ukubekwa emgwaqweni. Izindleko zomngcele wokuhlanganisa lezizici ziphansi kakhulu kunemisebenzi ehlukene. Ngaphezu komjikelezo wokuhlelwa kwenhloko yeminyaka eyisihlanu kuya kweyishumi, lokhu kuhlanganiswa kungasheshisa ngokuphawulekayo ukufakwa kwezakhiwo eziluhlaza edolobheni ngaphandle kokufuna izakhiwo ezintsha ezihlelelwe imali.

Ukusekela Ukusekela Imali Ngemizila Ehlukahlukene

Ukukhokha imali kuhlala kusenye yezinselele ezingapheli kubaphathi bedolobha abafuna izakhiwo eziluhlaza. Izimali zikamasipala ngokuvamile zintula izinto ezinikezelwe kulemisebenzi, futhi ukuncintisana ngezimali zokwahlulela kukhulu. Abaphathi bamadolobha abaphumelela kakhulu bahlanganisa imithombo yabo yezimali, izimali zikahulumeni, izibopho zikamasipala, izibopho zomphakathi, kanye nezakhiwo zezemali.

Izinhlelo Zokunikeza Imali Kahulumeni NoMbuso

I-EPA’s Clean Water State Revo Commoling Fund (CWSRF) iye yaba umthombo omkhulu wezimali zemisebenzi yezemisebenzi eluhlaza e-operali e-United States. Izifundazwe eziningi futhi ziye zanikezela izinhlelo zokunikeza ukulawulwa kwamanzi okunesiphepho nokuzinziswa kwesimo sezulu. Abaphathi bedolobha kufanele banikeze izisebenzi ukuba zinikeze amathuba futhi zakhe ubuhlobo nezikhulu zezendawo ezungezile ezinganikeza ukuqaphela izimali ezisheshayo.

iEPA's Green Infrastructive Fund Bearming Marks idweba izinhlelo zikahulumeni zamanje ezingampompa amadolobha, kuhlanganise nezipho zokuncintisana ngeManzi Inkstracturactal Memorial nange-innovation Act (WIFIA) ne-Community Development Block Grants (CDBG). Kubalulekile ukuqaphela ukuthi eziningi zalezi zinhlelo zidinga izimali ezilinganayo noma ukubonisa isidingo sezimali, ngakho abaphathi bedolobha badinga ukulungiselela izinhlelo eziqinile ezithuthukisa izomnotho nezinzuzo zemisebenzi ehlongozwayo.

Imikhumbi - mkhathi Yomphakathi Nemikhumbi - mkhathi

Abaphathi bamadolobha abacabangayo baphendukela kakhulu emkhakheni wezezimali ezingokotshani. Izinhlangano ezinkulu ezinezibopho ezisekela ukugcinwa kwemithi zingaxhasa izinhlelo zokutshala izihlahla noma imisebenzi yasemgwaqweni eluhlaza njengengxenye yezinyathelo zabo ezithatha imvelo, izenhlalo, nezokubusa (ESG). Abathuthuki bangadingeka noma bahlohlwa ukuba bahlanganise izisekeli eziluhlaza emikhankasweni yokwakha entsha ngokuhlela imithetho noma ngezibhodlo ezisindayo.

Izindleko zezethumbu lamanzi zimelela enye indlela entsha yokuxhasa imali. Ngokufuna abanikazi bempahla abasekelwe ezindaweni ezingangenwa yilutho ezweni labo, amadolobha akha umsele wemali onikezelwe ukuze kuncishiswe izakhiwo eziluhlaza kodwa futhi ancishise abanikazi bempahla. Amadolobha amaningi anikeza izikweleti noma intengo yezakhiwo ezifaka izinga lemvula, imigwaqo evulekile, noma uphahla oluluhlaza, ebangela umjikelezo omuhle wokutshala imali kubantu abasendaweni yomphakathi.

Izibopho Zangaphakathi Nezibopho Ezinethonya Endaweni Ezungezile

Izibopho zikaMasipala eziluhlaza zithandwa ngokushesha njengendlela yokusekela imisebenzi ezuzisayo yendawo ezungezile. Lezi zivumelwano zinikeza izimpawu kubatshali bezimali ezizosetshenziswa ezinjongweni ezichaziwe eziluhlaza, ngokuvamile zidonsela isikhungo esibanzi sezezimali nezinga lenzalo eliphansi. Imiphumela yendawo ezungezile ithatha lombono ngokuhlanganisa ukukhokha inzalo efezweni kwemiphumela ethile yendawo ezungezile, ihlanganyela ingozi phakathi komasipala nabanikazi bezimali.

Abaphathi bedolobha abasebenza eminyangweni yezezimali bangahlanganisa izibopho ezixhasa izakhiwo zezakhiwo zezakhiwo eziluhlaza, zisakaza ingozi ezindaweni eziningi nasezindaweni eziningi zokungenela. Ukubonisa izimpawu ngemiphumela kubaluleke kakhulu ekulondolozeni ukuthembana kwezimali nokwakha irekhodi lesibopho sesikhathi esizayo.

Ukuhlanganyela Komphakathi Okwakha Ukusekelwa Okuhlala Njalo

Awukho umsebenzi wobuchwepheshe noma ukuxhaswa kwezimali ozophumelela uma umphakathi ungawusekeli umsebenzi wezakhiwo eziluhlaza.
