Ucwaningo: Amahlathi asezindaweni ezishisayo akhiqiza kabusha ngokushesha kunokulindelekile

a cwaningo, esanda kunyatheliswa kuyi-Science, ibonisa "ukuthi amahlathi asezindaweni ezishisayo akhula kabusha angalulama ngokushesha futhi ngemva kweminyaka engu-20 angafinyelela cishe ku-80% wokuvunda kwenhlabathi, ukugcinwa kwekhabhoni kanye nezinhlobonhlobo zezihlahla zamahlathi amadala."

Ngakho-ke ukuvuselelwa kwemvelo kuyisixazululo esingabizi kakhulu, esisekelwe emvelweni sokuvikela isimo sezulu, ukulondolozwa kwezinhlobonhlobo zezinto eziphilayo kanye nokubuyiselwa kwemvelo.

Umbhali wokuqala, uProfesa Lourens Poorter waseNyuvesi yaseWageningen eNetherlands, uyachaza encwadini ye-BOKU: “Nokho, isivinini sokululama siyahlukahluka kuye ngezici ezilinganisiwe zamahlathi: ukutholwa kuka-90% wamanani. yamahlathi amadala iyona eshesha kakhulu ekuvundeni kwenhlabathi (iminyaka engaphansi kwe-10) nemisebenzi yezitshalo (iminyaka engaphansi kwe-25), isivinini esimaphakathi sokwakheka kwehlathi kanye nezinhlobonhlobo zezinto eziphilayo (iminyaka engama-25-60) futhi ihamba kancane ku-biomass engaphezu komhlaba kanye nokwakheka kwezinhlobo (ngaphezulu ngaphezu kweminyaka eyi-120).

U-Peter Hietz ​​​​ovela e-University of Natural Resources and Life Sciences (BOKU) naye ubambe iqhaza ocwaningweni. Uthi, “Kuseyinkolelo evamile ukuthi lapho izihlahla sezigawuliwe, amahlathi emvula ashabalala unomphela. Umsebenzi oshicilelwe ubonisa ngokucacile ukuthi lokhu akunjalo futhi ukuthi ezimweni eziningi ukuvuselelwa kungenziwa ngokushesha ngokumangalisayo. Kodwa lokho akwenzeki ngaso sonke isikhathi ngokushesha futhi kubalulekile ukuqonda ukuthi kungani amanye amahlathi ekhula ngokushesha kanti amanye ehamba kancane. Ngokwesibonelo, emahlathini aseCosta Rica, siye sabona ukuthi lokhu kuxhomeke ohlotsheni lokusetshenziswa nenhlabathi. Uma sikuqonda kangcono lokhu, singavikela amahlathi akhula kabi ikakhulukazi, noma sikhuthaze ukukhiqizwa kabusha ngezinyathelo ezihlosiwe. "
