Uphononongo: Amahlathi eTropiki akhula ngokukhawuleza kunokuba bekulindelwe

a isifundo, esandul’ ukupapashwa kwi<em>Science, ibonisa “ukuba amahlathi ashinyeneyo akhula ngokutsha anokubuyiselwa ngokukhawuleza okumangalisayo yaye emva kweminyaka engama-20 anokufikelela phantse kuma-80 ekhulwini okuchumisa komhlaba, ukugcinwa kwekhabhoni neentlobo ngeentlobo zemithi yamahlathi amadala.”

Uhlaziyo lwendalo ke ngoko luyindleko esebenzayo, isisombululo esisekelwe kwindalo sokukhusela imozulu, ukugcinwa kweentlobo ngeentlobo zezinto eziphilayo kunye nokubuyiselwa kwenkqubo yendalo.

Umbhali wokuqala, uNjingalwazi uLourens Poorter ovela kwiYunivesithi yaseWageningen eNetherlands, uchaza kwimpapasho ye-BOKU: "Isantya sokubuyisela, nangona kunjalo, siyahluka kakhulu kuxhomekeke kwiipropati ezilinganisiweyo zamahlathi: ukubuyiswa kwe-90% yexabiso. Amahlathi amadala yeyona nto ikhawulezayo yokuchuma komhlaba (ngaphantsi kweminyaka eyi-10) kunye nemisebenzi yezityalo (ngaphantsi kweminyaka engama-25), isantya esiphakathi kulwakhiwo lwehlathi kunye neentlobo ngeentlobo zezinto eziphilayo (iminyaka eyi-25-60) kwaye icotha kwi-biomass engaphezulu komhlaba kunye nokwakheka kweentlobo (ngaphezulu ngaphezu kweminyaka eyi-120).

UPeter Hietz ​​ovela kwiDyunivesithi yezeNdalo kunye neSayensi yoBomi (BOKU) naye wayebandakanyeka kuphononongo. Uthi, “Kuseyinkolelo ethandwayo ukuba yakuba igawulwe imithi, amahlathi ashinyeneyo atshabalala ngonaphakade. Umsebenzi oshicilelweyo ubonisa ngokucacileyo ukuba oku akunjalo kwaye kwiimeko ezininzi ukuvuselelwa kunokuthi kwenzeke ngokumangalisayo ngokukhawuleza. Kodwa oko akusoloko kusenzeka ngokukhawuleza kwaye kubalulekile ukuqonda ukuba kutheni amanye amahlathi ekhula ngokukhawuleza kwaye amanye acotha. Ngokomzekelo, kumahlathi aseCosta Rica, siye sabona ukuba oku kuxhomekeke kuhlobo lokuwusebenzisa nomhlaba. Ukuba siyayiqonda le nto ngcono, sinokukhusela amahlathi aphinda ahlaziywe kakubi, okanye akhuthaze ukuvuselelwa ngokutsha ngamanyathelo ekujoliswe kuwo.
