Campania masiv\u0103 de \u00eemp\u0103durire a Chinei \u00een jurul de\u0219ertului Taklamakan transform\u0103 unul dintre cele mai dure peisaje din lume.<\/p>\n

Noile cercet\u0103ri sugereaz\u0103 c\u0103 fostul \u201evid biologic\u201d absoarbe acum mai mult dioxid de carbon dec\u00e2t emite, scrie LiveScience<\/a><\/span>.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 spun c\u0103 este primul caz clar \u00een care marginea unui de\u0219ert se transform\u0103 \u00eentr-un rezervor natural de carbon.<\/p>\n

De\u0219ertul Taklamakan se \u00eentinde pe aproximativ 337.000 de kilometri p\u0103tra\u021bi \u00een nord-vestul Chinei. \u00cenconjurat de mun\u021bi, prime\u0219te foarte pu\u021bin\u0103 umiditate \u0219i r\u0103m\u00e2ne extrem de arid. Peste 95% din suprafa\u021ba sa este acoperit\u0103 de nisipuri mi\u0219c\u0103toare.<\/p>\n

Proiectul Marele Zid Verde<\/h2>\n

\u00cen 1978, China a lansat Programul Centurii Forestiere din Nord, cunoscut drept Marele Zid Verde. Ini\u021biativa a urm\u0103rit plantarea a miliarde de copaci pentru a combate de\u0219ertificarea.<\/p>\n

P\u00e2n\u0103 \u00een prezent, peste 66 de miliarde de copaci au fost planta\u021bi \u00een nordul Chinei. Din 2024, vegeta\u021bia \u00eenconjoar\u0103 complet de\u0219ertul Taklamakan.<\/p>\n

Suprafa\u021ba \u00eemp\u0103durit\u0103 la nivel na\u021bional a crescut de la 10% \u00een 1949 la peste 25% ast\u0103zi. Cercet\u0103torii spun c\u0103 centura verde a stabilizat dunele de nisip de la marginea de\u0219ertului.<\/p>\n

Dovezi privind cre\u0219terea absorb\u021biei de carbon<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 au analizat 25 de ani de date satelitare \u0219i observa\u021bii la sol. Au studiat precipita\u021biile, cre\u0219terea vegeta\u021biei, ratele de fotosintez\u0103 \u0219i nivelurile de dioxid de carbon.<\/p>\n

Rezultatele arat\u0103 o extindere a vegeta\u021biei de-a lungul marginilor de\u0219ertului. \u00cen sezonul umed, \u00eentre iulie \u0219i septembrie, cantitatea de precipita\u021bii cre\u0219te semnificativ. Acest lucru stimuleaz\u0103 cre\u0219terea plantelor \u0219i fotosinteza.<\/p>\n

Nivelurile de CO2 scad de la 416 p\u0103r\u021bi per milion \u00een sezonul uscat la 413 ppm \u00een sezonul umed. Cercet\u0103torii concluzioneaz\u0103 c\u0103 vegeta\u021bia de la margine absoarbe mai mult CO2 dec\u00e2t elibereaz\u0103 de\u0219ertul.<\/p>\n

Studiile anterioare se concentrau pe absorb\u021bia realizat\u0103 de nisip, considerat\u0103 instabil\u0103 \u00een contextul schimb\u0103rilor climatice.<\/p>\n

Un model pentru alte regiuni de\u0219ertice<\/h2>\n

Rezultatele au fost publicate \u00een revista PNAS. Oamenii de \u0219tiin\u021b\u0103 spun c\u0103 Taklamakan reprezint\u0103 acum un model func\u021bional de captare a carbonului \u00een zone de\u0219ertice.<\/p>\n

Totu\u0219i, dezbaterile continu\u0103 privind impactul proiectului asupra frecven\u021bei furtunilor de nisip.<\/p>\n

Exper\u021bii sus\u021bin c\u0103 Marele Zid Verde ar putea inspira ini\u021biative similare la nivel global.<\/p>\n","protected":false},"excerpt":{"rendered":"
