Medelhavets marina liv hotas: WWF-rapporten belyser sex milj\u00f6skador under v\u00e5gorna orsakade av klimatkrisen<\/p><\/div>\n<\/div>\n

WWF-rapporten belyser sex milj\u00f6skador under v\u00e5gorna orsakade av klimatkrisen<\/h2>\n

 <\/p>\n

Det uppskattas att 80-100% av bl\u00e5musselpopulationer nyligen f\u00f6rlorades under en pl\u00f6tslig \u00f6kning av d\u00f6dligheten i Spanien, Italien och andra regioner i Medelhavsomr\u00e5det, medan 30% av alla r\u00f6da koraller f\u00f6rst\u00f6rdes av en enda storm.<\/p>\n<\/div>\n

\n

Tropicaliseringen i Medelhavet \u00e4r skenande, med temperaturer som stiger 20% snabbare \u00e4n det globala genomsnittet, fiskar som vandrar, invasiva arter dyker upp medan inhemska arter f\u00f6rsvinner, marina angiosperm havs\u00e4ngar och korallrev f\u00f6rst\u00f6rs och manetpopulationer sprider sig. Ovanst\u00e5ende konsekvenser av klimatkrisen p\u00e5 Medelhavet avsl\u00f6jas i en f\u00e4rsk rapport fr\u00e5n V\u00e4rldsnaturfonden med titeln "The Climate Change Effect in the Mediterranean: Six Stories from an Overheating Sea." Rapporten f\u00f6rklarar ytterligare de sex f\u00f6ljande prim\u00e4ra effekterna av klimatf\u00f6r\u00e4ndringar p\u00e5 Medelhavet:<\/p>\n

Den \u00f6kade vattentemperaturen skapar "tropiska" f\u00f6rh\u00e5llanden; resultatet \u00e4r att inhemska arter antingen f\u00f6rdrivs eller d\u00f6r ut.<\/p>\n

N\u00e4stan 1 000 nya fr\u00e4mmande arter (av dessa \u00e4r 126 fiskar) har kommit in i Medelhavet, vilket har orsakat en minskning av inhemska populationer. I israeliska vatten har inhemska bl\u00f6tdjurspopulationer minskat med cirka 90%, medan fr\u00e4mmande arter, inklusive den m\u00f6rka ryggfotsfisken, nu utg\u00f6r 80% av f\u00e5ngsten i Turkiet. Parallellt p\u00e5tr\u00e4ffas nu arter fr\u00e5n l\u00e4ngre s\u00f6derut, som barracuda och dunkla havabborre, utanf\u00f6r Liguriens kust i norra Italien.<\/p>\n

Det har skett en betydande \u00f6kning av manetpopulationer, s\u00e4rskilt i de s\u00f6dra regionerna, som har upplevt allt oftare och l\u00e5ngvariga befolkningsexplosioner. L\u00e5ngvarigt \u00f6verfiske har drastiskt minskat populationerna av fiskarter som tidigare konkurrerade med maneter om maten och idag f\u00e5ngar vissa fiskare fler maneter \u00e4n fiskar.<\/p>\n

Neptunus gr\u00e4s\u00e4ngar hotas av allt varmare vatten och en stigande havsniv\u00e5, vilket har haft en f\u00f6r\u00f6dande inverkan p\u00e5 b\u00e5de biologisk m\u00e5ngfald och lagring av "bl\u00e5tt kol" - det vill s\u00e4ga de marina v\u00e4xterna som absorberar koldioxid fr\u00e5n atmosf\u00e4ren. Det uppskattas att Neptunus gr\u00e4s\u00e4ngar lagrar 11-42% av Medelhavsomr\u00e5dets CO2-utsl\u00e4pp.<\/p>\n

Cirka 30% av all r\u00f6d korall som best\u00e5r av gorgonier, eller havsfans, i Liguriska havet f\u00f6rst\u00f6rdes efter en enda storm i oktober 2018. Dessutom f\u00f6rst\u00f6rs m\u00e5nga andra typer av koraller som bidrar till komplexa medelhavsekosystem av extrema v\u00e4derfenomen med v\u00e4xande frekvens.<\/p>\n

Uppskattningsvis 80-100% av bl\u00e5musselpopulationer f\u00f6rlorades nyligen utanf\u00f6r Spanien, Italien och andra regioner p\u00e5 grund av \u00f6kande d\u00f6dlighet. Denna tv\u00e5skaliga bl\u00f6tdjur, den st\u00f6rsta endemiska bl\u00f6tdjuren i Medelhavet, ger skydd \u00e5t 146 andra, mindre arter.<\/p>\n

WWF-rapporten pekar p\u00e5 det farliga f\u00f6rh\u00e5llandet mellan effekterna av klimatf\u00f6r\u00e4ndringar \u00e5 ena sidan, och de som provoceras av direkt m\u00e4nsklig press p\u00e5 det marina livet, genom \u00f6verfiske, f\u00f6roreningar, kustutveckling och segling \u00e5 andra sidan.<\/p>\n

En avg\u00f6rande \u00e5tg\u00e4rd som \u00e4r n\u00f6dv\u00e4ndig f\u00f6r att stoppa v\u00e5r negativa p\u00e5verkan p\u00e5 havet \u00e4r skapandet och effektiv f\u00f6rvaltning av marina skyddade omr\u00e5den (MPA). Idag t\u00e4cker s\u00e5dana omr\u00e5den bara 9.68% av Medelhavet, varav endast 1.27% \u00e4r v\u00e4sentligt reglerat. Nyligen noterade forskning fr\u00e5n WWF Mediterranean Marine Initiative att 30% i Medelhavet skulle beh\u00f6va skyddas f\u00f6r att b\u00f6rja \u00e5terst\u00e4lla ekosystemen, till\u00e5ta fiskpopulationer att \u00e5terh\u00e4mta sig, mildra effekterna av klimatf\u00f6r\u00e4ndringar och s\u00e4kerst\u00e4lla h\u00e5llbart fiske och turism samt livsmedelss\u00e4kerhet och v\u00e4lst\u00e5nd f\u00f6r lokalsamh\u00e4llen. Panagiota Maragou, naturv\u00e5rdsdirekt\u00f6r vid WWF Grekland, noterade, "Vi siktar p\u00e5 att skydda 30% i Medelhavet med effektiva f\u00f6rvaltnings\u00e5tg\u00e4rder f\u00f6r att minska trycket p\u00e5 ekosystemen och hj\u00e4lpa dem att bli motst\u00e5ndskraftiga mot klimatkrisen, samtidigt som vi ompr\u00f6var s\u00e4ttet p\u00e5 vilket vi anv\u00e4nder naturresurser.\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
