Umthelela Wezamanzi Nenhlabathi

Impilo yezinhlelo zamanzi nomhlabathi weplanethi yethu ixhumene kakhulu nezinqubo zezolimo, futhi ukufuywa kwezilwane ezimbonini kunomthelela omubi kakhulu. Imfuyo emikhulu ikhiqiza imfucuza eningi, evame ukungena emifuleni, emachibini, namanzi angaphansi komhlaba, ingcolise imithombo yamanzi nge-nitrogen, i-phosphorus, imithi elwa namagciwane namagciwane. Lokhu kungcola kuphazamisa imvelo yasemanzini, kusongela impilo yabantu, futhi kunomthelela ekwandeni kwezindawo ezifile olwandle nasezindaweni ezihlala emanzini ahlanzekile.
Umhlabathi, isisekelo sokuvikeleka kokudla emhlabeni wonke, uhlupheka ngokulinganayo ngaphansi kokufuywa kwezilwane ngamandla. Ukudlisa ngokweqile, izitshalo zokuphakela i-monoculture, kanye nokuphathwa kabi komquba kuholela ekugugulekeni, ekuncipheni komsoco, nasekulahlekeni kokuvunda kwenhlabathi. Ukuwohloka kwenhlabathi engaphezulu akugcini nje ngokubukela phansi ukukhiqizwa kwezitshalo kodwa futhi kunciphisa amandla emvelo omhlaba okumunca ikhabhoni futhi alawule imijikelezo yamanzi, kuqinise kokubili isomiso nezikhukhula.
Lesi sigaba sigcizelela ukuthi ukuvikela amanzi nomhlabathi kubalulekile ekusimameni kwemvelo nempilo yabantu. Ngokugqamisa umthelela wokulima kwasefekthri kulezi zinsiza ezibalulekile, kukhuthaza ukushintshela ezindleleni zezolimo ezivuselelayo, ukuphathwa kwamanzi okunesibopho, kanye nokudla okunciphisa ubunzima kuzinhlelo zemvelo ezibalulekile zeplanethi yethu.

Hlola umthelela omkhulu wemvelo wenyama nowabisi, kusuka kuma-greenhouse kaphethiloli kuya ekuqothulweni kwamahlathi, ukungcoliswa kwamanzi, kanye nokulahleka kwezinto eziphilayo. Ezolimo Zezilwane zibeka ingcindezi enkulu emisebenzini yeplanethi yethu, ukushayela kwesimo sezulu kanye nokungalingani kwemvelo. Ngokuqonda lezi zinselelo, singathatha izinyathelo ezinengqondo zokusimama - noma ngabe ngokunciphisa ukudla, ukukhetha ezinye izindlela ezenzelwe izitshalo, noma ukusekela ubuchwepheshe bokudla obusha. Njalo isinqumo esiqondayo sinomthelela kwikusasa eliluhlaza okwesibhakabhaka lomhlaba wethu kanye nemvelo yalo

Ukuswela amanzi kuyavela njengezinkinga zomhlaba wonke, kwaqiniswa ukuguquguquka kwesimo sezulu kanye nemikhuba engaphephile. Phakathi kwalolu daba kunguzolimo zezilwane - umshayeli omkhulu ovame ukwenziwa ngaphansi kwamanzi amasha. Ukusuka emanzini amakhulu okusetshenziswa kwezilimo okuphakelayo ekungcoleni nasekukhishweni kwe-aquifer ngokweqile, ukulima kwezimboni kubeka ingcindezi enkulu ekuhlinzekweni kwamanzi okuncipha. Lo mbhalo uhlola ukuxhumana okuvusa umsindo phakathi kwezolimo zezilwane kanye nokushoda kwamanzi, ama-delves ezibonelweni zangempela zomhlaba ezinjenge-california ephakathi nendawo kanye nomkhakha wenyama yenyama ye-california, bese ubeka izixazululo ezisebenzayo zokuvikela izinhlelo zokudla ezibalulekile

Hlola imiphumela yezemvelo yokukhiqizwa kwenyama ku- * "Umthwalo wenkomo: Ukuhlola izindleko zemvelo zokukhiqizwa kwenyama. Ukusuka kuma-algal blooms okubangelwa ukugibela kwezolimo ku-Methane Emissions Ukushayela Kwezimo Zokushayela Kwesimo sezulu, umkhakha wezinyawo wenyama ufinyelela ububanzi futhi uphuthumayo. Funda ngezindlela ezizinzileyo ezinjengokudla okususelwa ekudleni, imikhuba yokulima kabusha, kanye nezixazululo ezintsha njengenyama esolwa ezingasiza ukunciphisa imiphumela. Sekuyisikhathi sokucabanga kabusha izinhlelo zethu zokudla zeplanethi enempilo

Ngokukhulisa ukukhathazeka okukhulayo kwezemvelo, izinqumo esizenzayo ngesikhathi sokudla zibambe amathuba amangalisayo okushintsha. Ukudla okususelwa kwizitshalo kunikeza indlela eqhubekayo yokunciphisa ukuphuma kwegesi abamba ukushisa, kulondolozwa izinsiza zemvelo, nokuvikela izinto eziphilayo. Ngokunciphisa ukuthembela kwezolimo kwezinsizakusebenza ezinamandla, le ndlela yokuqonda i-ecoult isiza ukulwa nokushintshwa kwesimo sezulu ngenkathi sibheka ukungavikeleki komhlaba wonke. Ngale kwalezinzuzo zayo zeplanethi, indlela yokuphila enamandla yesitshalo nayo ibuye inyusa impilo engcono nenhlala-kahle. Hlola ukuthi isidlo ngakunye singaba yisinyathelo esinengqondo sokuvikela iplanethi yethu futhi sakha ikusasa elizinzile kakhulu kubo bonke

Ukuqwashisa okukhulayo kokuwohloka kwemvelo kubeke indawo ebonakalayo endimeni yokudla kwethu ekubumbeni ikusasa elizinzile. Ukukhiqizwa kokudla okususelwa ezilwaneni kungumthelela oholayo ekuqothulweni kwamahlathi, ukuphuma kwegesi abamba ukushisa, ukuswelakala kwamanzi, kanye nezinkinga zokungcola ezisongela imvelo kanye nezinto eziphilayo emhlabeni wonke. Ukushintshela ekudleni okususelwa ekudleni, okubeka kuqala izithelo, imifino, okusanhlamvu, ama-legumes, namantongomane ngenkathi kunciphisa noma ukuqeda imikhiqizo yezilwane, kunikeza indlela enamandla yokubhekana nalezi zinselelo. Ngokukhetha izinketho ezenzelwe izitshalo, singakwazi ukwehlisa kakhulu i-carbon footprint yethu, zilondoloze izinsiza ezibalulekile njengamanzi nomhlaba, bese zinciphisa ukulimala kwemvelo. Lo mbhalo uhlola ukuthi ukwamukela ukudla okususelwa kwisitshalo kungashayela inqubekela phambili enengqondo ekuvikeleni iplanethi yezizukulwane ezizayo

Ukulima imfucumfucu bekulokhu kuyitshe lezitsheni zokondla komuntu kanye nomsebenzi wezomnotho, kepha unyawo lwalo lwezemvelo luphakamisa ukukhathazeka okuphuthumayo. Isidingo esikhuphukayo senyama nemibi kabisi edonsayo, isheshisa ukuphuma kwamaphethelo abamba ukushisa, ichithe izinsiza zamanzi, futhi iphazamise izinsiza zamanzi. Le miphumela yokuphamba iqinisa ukuguquguquka kwesimo sezulu ngenkathi kufakwa engcupheni imvelo ebalulekile empilweni emhlabeni. Njengoba ukuqwashisa kukhula, ukudla okususelwa ekulimaleni kanye nemikhuba yokulima esimeme ivela njengezindlela ezisebenzayo zokunciphisa le miphumela. Lo mbhalo uhlola imiphumela yezemvelo yokukhiqizwa kwemfuyo kanye namaphuzu avelele ukuthi amashifu okudla aziwazi kangakanani angaba nesandla kwiplanethi enempilo kanye nohlelo lokudla okukhona ngokwengeziwe

Ukulima efektri kuye kwalungisa kabusha ezolimo zomhlaba, okwenza ukukhiqizwa kwenyama, ubisi namaqanda amaningi ukuze kuhlangatshezwane nezidingo ezikhulayo. Kodwa-ke le ndlela ethuthukile ithwala izindleko ezinzima zemvelo, kufaka phakathi ukugawulwa kwamahlathi, ukuguguleka kwenhlabathi, ukungcoliswa kwamanzi, kanye nokukhishwa okukhulu kwegesi okuluhlaza okotshani. Imiphumela yayo yokubumba inwebeka ekulahlekelweni kwezinto eziphilayo kanye nokukhathazeka kwezempilo yomphakathi okuxhunyaniswe nokumelana namagciwane nokungcola. Lo mbhalo uhlola ukuwa kwemvelo kwezolimo efektri ngombono womhlaba wonke ngenkathi ugqamisa amabutho ezomnotho aqhuba ukwanda kwawo. Ngokuhlola izixazululo ezizinzileyo kanye nemikhuba yokuziphatha, singabhekana nalezi zinselelo futhi sisebenzele ohlelweni lokudla oluqhubekela phambili nokuqina kwemvelo kanye nokuqina kwesikhathi eside
