D\u0117l did\u0117jan\u010dio druskingumo Azovo j\u016broje kei\u010diasi \u017euv\u0173 r\u016b\u0161in\u0117 sud\u0117tis, o daliai tradicini\u0173 r\u016b\u0161i\u0173 s\u0105lygos tampa nepalankios.<\/p>\n
Apie tai vie\u0161ai prane\u0161\u0117 Okupacijos tyrim\u0173 centro vadovas Petro Andriu\u0161\u010denka, teigdamas, kad d\u0117l karo ir su juo susijusi\u0173 poky\u010di\u0173 Azovo j\u016bra patiria ilgalaik\u0119 ekologin\u0119 transformacij\u0105.<\/p>\n
Jo teigimu, vienas ry\u0161kiausi\u0173 signal\u0173 yra augantis vandens druskingumas, kuris, lyginant su ankstesniais de\u0161imtme\u010diais, pasiek\u0117 nauj\u0105 lyg\u012f. Skelbiama, kad iki 2007 met\u0173 vidutinis Azovo j\u016bros druskingumas siek\u0117 apie 10 promili\u0173, o dabar priart\u0117jo prie ma\u017edaug 15 promili\u0173.<\/p>\n
Palyginimui, Juodosios j\u016bros druskingumas paprastai siekia apie 18 promili\u0173, tad Azovo j\u016bra pagal \u0161\u012f rodikl\u012f art\u0117ja prie j\u016brinio, o ne g\u0117lavandenio ir s\u016brokavandenio telkinio charakteristik\u0173.<\/p>\n
Kas kei\u010diasi ekosistemoje?<\/p>\n
Did\u0117jantis druskingumas kei\u010dia s\u0105lygas, kuriomis vystosi ir dauginasi skirtingos \u017euv\u0173 r\u016b\u0161ys. Andriu\u0161\u010denka atkreip\u0117 d\u0117mes\u012f \u012f Rusijos skelbiamus teiginius, kad vienos i\u0161 j\u016brini\u0173 \u017euv\u0173 populiacija per metus es\u0105 i\u0161augo apie 30 proc., ir tai siejama b\u016btent su palankesn\u0117mis s\u0105lygomis nat\u016braliam \u0161ios r\u016b\u0161ies atsik\u016brimui.<\/p>\n
Tuo pat metu, jo teigimu, ma\u017e\u0117ja smulki\u0173 \u017euv\u0173 atsargos, o tarp prie\u017eas\u010di\u0173 minimas ma\u017eas vandeningumas pastaraisiais metais ir ma\u017e\u0117jantis upi\u0173 nuot\u0117kis. Tai dar labiau skatina vandens drusk\u0117jim\u0105, ypa\u010d \u012flankose ir pakrant\u0117s zonose.<\/p>\n
Kokios gali b\u016bti pasekm\u0117s \u017evejybai?<\/p>\n
Vertinant ekologin\u012f poslink\u012f, vis daugiau prana\u0161umo gali \u012fgyti j\u016brin\u0117s r\u016b\u0161ys, o s\u016brokavandeniams ir g\u0117lavandeniams artimoms r\u016b\u0161ims tinkam\u0173 buveini\u0173 ma\u017e\u0117s. Anot Andriu\u0161\u010denkos, d\u0117l to ateityje gali trauktis tokios r\u016b\u0161ys, kurioms reikia ma\u017eesnio druskingumo.<\/p>\n
\u201eRusija nu\u017eud\u0117 Azovo j\u016br\u0105. Tiesiogine prasme\u201c, \u2013 sak\u0117 Petro Andriu\u0161\u010denka.<\/p>\n
Jis taip pat persp\u0117jo, kad ilgalaik\u0117je perspektyvoje gali i\u0161augti rizika kai kuri\u0173 verting\u0173 r\u016b\u0161i\u0173 i\u0161nykimui, o tai pakeist\u0173 ir pramonin\u0117s \u017evejybos strukt\u016br\u0105. Tokie poky\u010diai reik\u0161t\u0173, kad regione dominuot\u0173 kitokios \u017euv\u0173 r\u016b\u0161ys, o tradicin\u0117s \u017evejybos kryptys prarast\u0173 ekonomin\u012f pagrind\u0105.<\/p>\n
Azovo j\u016bros b\u016bkl\u0119 papildomai apsunkina karo poveikis pakrantei, intensyvesn\u0117 i\u0161tekli\u0173 eksploatacija ir infrastrukt\u016bros pertvarkymai okupuotose teritorijose, kurie, ekspert\u0173 vertinimu, gali tur\u0117ti ilgalaiki\u0173 pasekmi\u0173 visai ekosistemai.<\/p>\n","protected":false},"excerpt":{"rendered":"
