\nSchimb\u0103rile climatice provoac\u0103 o uscare f\u0103r\u0103 precedent a solului, iar cinci miliarde de oameni ar putea fi afecta\u0163i p\u00e2n\u0103 \u00een 2100, scrie \u00eentr-un nou raport al ONU citat de Live Science. Documentul arat\u0103 c\u0103 \u00een ultimele trei decenii, schimb\u0103rile climei au agravat uscarea a trei sferturi din sol. 77,6% din solul planetei a devenit mai uscat \u00een ultimele trei decenii comparativ cu deceniile anterioare. Zonele uscate s-au extins pe o suprafa\u0163\u0103 mai mare dec\u00e2t India.<\/p>\n
\nConcluziile publicate \u00eentr-un nou raport al Conven\u0163iei ONU de Combatere a De\u015fertific\u0103rii ((UNCCD) avertizeaz\u0103 c\u0103, dac\u0103 tendin\u0163a continu\u0103, p\u00e2n\u0103 la cinci miliarde de oameni ar putea tr\u0103i \u00een zone uscate p\u00e2n\u0103 la sf\u00e2r\u015fitul secolului. Acest lucru \u00eenseamn\u0103 c\u0103 nu se va mai putea face agricultur\u0103, nu vor mai fi resurse de ap\u0103, iar ecosistemele se vor pr\u0103bu\u015fi.<\/p>\n
\n\u201ePentru prima dat\u0103, criza de ariditate a fost documentat\u0103 cu claritate \u015ftiin\u0163ific\u0103, dezv\u0103luind o amenin\u0163are existen\u0163ial\u0103 care afecteaz\u0103 miliarde de pe tot globul. C\u00e2nd clima unei zone devine mai uscat\u0103, capacitatea de a reveni la condi\u0163iile anterioare se pierde. Clima mai uscat\u0103 care afecteaz\u0103 acum teritorii vaste de pe tot globul nu \u00ee\u015fi va reveni \u015fi aceast\u0103 schimbare redefine\u015fte via\u0163a pe P\u0103m\u00e2nt\u201d, a declarat Ibrahim Thiaw, secretarul executiv al UNCCD, \u00eentr-un comunicat.<\/p>\n
\nAutorii raportului au folosit modele climatice avansate \u015fi alte tehnici moderne pentru a ob\u0163ine o imagine clar\u0103 a tendin\u0163ei de uscare \u00een cre\u015ftere. Descoperirile lor sunt dure: ariditatea afecteaz\u0103 40% din terenurile agricole ale lumii \u015fi 2,3 miliarde de oameni, provoc\u00e2nd incendii de vegeta\u0163ie intensificate, pr\u0103bu\u015firea agriculturii \u015fi migra\u0163ii \u00een mas\u0103. Zonele deosebit de afectate includ toat\u0103 Europa, vestul SUA, Brazilia, Asia de Est \u015fi Africa Central\u0103.<\/p>\n
\nPentru a \u00eencetini uscarea solului, oamenirea trebuie s\u0103 ia m\u0103suri urgente \u015fi radicale.<\/p>\n
\n\u201eF\u0103r\u0103 eforturi concertate, miliarde de oameni se confrunt\u0103 cu un viitor marcat de foamete, str\u0103mutare \u015fi declin economic\u201d, a spus Barron Orr, om de \u015ftiin\u0163\u0103 al UNCCD.<\/p>\n","protected":false},"excerpt":{"rendered":"
