I-India neChina benza umhlaba uluhlaza

I-India neChina bahola umzamo wokuba oluhlaza okotshani, kusho isifundo sakamuva seNASA ngoMsombuluko, sibheka ukuthi umhlaba uyindawo eluhlaza okwenzeka eminyakeni engama-20 edlule.

Ucwaningo olushicilelwe ejeni 'Imvelo Sustainability' uthe idatha yakamuva ye-satellite iveza iphethini eluhlaza egqamile evelele eChina naseNdiya kanye nokubheqeka ngama-croplands ububanzi emhlabeni wonke.

Idatha evela ku-Nasa Earth Satellites ikhombisa ukuthi umsebenzi wabantu eChina naseNdiya ubusa lokhu kuhlaza komhlaba, ngenxa yokutshala isihlahla nezolimo.

Umphumela uvela kakhulu ezinhlelweni zokutshala izihlahla zokuhlala ezifuywayo eChina naseZwelweni Ezenzulu kuwo womabili la mazwe.

"I-China neNdiya i-Akhawunti ye-One-ingxenye yesithathu yokuluhlaza," kusho umlobi we-lead Chi Chen waseBoston University.

"Lokho kungukuthola okumangazayo, ukucubungula umbono jikelele wokuwohloka komhlaba emazweni anabantu abaningi kusuka ku-overexploitation," kungezwa chen.

I-China yedwa ibangela amaphesenti angama-25 okunyuka kwamaqabunga emhlabeni jikelele endaweni yamaqabunga enamaphesenti ayi-6,6 kuphela wendawo enezitshalo zomhlaba.

Ukuhlaza eChina kuvela emahlathini (amaphesenti angama-42) kanye nama-croplands (amaphesenti angama-32), kepha eNdiya, ikakhulukazi kusuka kuma-croplands (amaphesenti angama-82) anomnikelo omncane emahlathini (amaphesenti angama-42).

Igalelo elishiwoyo laseChina kwinkanyezi eluhlaza okotshani liza engxenyeni enkulu ezinhlelweni zalo ukuze kulondolozwe futhi yandise amahlathi ngenhloso yokunciphisa ukonakaliswa komhlaba, ukungcoliswa komoya kanye nokushintsha kwesimo sezulu.

"Lapho ukukopela koMhlaba kuqala kubhekwe, sacabanga ukuthi kungenxa yesimo sezulu esifudumele, esimanzi kanye nokuvundiswa kusuka ku-carbon dioxide emkhathini. Manje sibona ukuthi abantu bayaba nesandla," kusho uRama UNenia, ucwaningo usosayensi eNasa's AMS Research Center kanye noMlobi wocwaningo.

"Lapho nje abantu bebona ukuthi kunenkinga, bathambekele ukuyilungisa. Ngo-1970s kanye nama-80s eNdiya naseChina, abantu bakubona, nanamuhla izinto sezithuthukile. Abantu baye ukuqina okukhulu. Yilokho esikubona kudatha ye-satellite, "kungezwa uNemana.

Indawo yomhlaba esetshenziselwa ukukhulisa izilimo ifaniswa eChina naseNdiya - amamayela skwele angaphezu kuka-770,000 - futhi awakashintshi okuningi kusukela ekuqaleni kuka-2000s. Kodwa-ke lezi zifunda ziye zanda kakhulu zombili izindawo zazo zonyaka eziphelele kanye nokukhiqizwa kwazo kokudla.

Lokhu kutholwe ngokusebenzisa izintambo eziningi zokutshala izitshalo, lapho insimu ibuyelwe khona ukukhiqiza esinye isivuno kaningana ngonyaka. Ukukhiqizwa okusanhlamvu, imifino, izithelo nokuningi kukhuphuke cishe ngama-35- 40% kusukela ngo-2000 ukondla abantu babo abakhulu.

Ngaphezu kwalokho, uma unentshisekelo ephepheni lesikebhe lesikebhe e- EVA noma i - EVA SUP Pad & Eva Traction Pad , sicela ukhululeke ukuxhumana nathi.
