Alergie prin\u00e1\u0161aj\u00fa nielen zdravotn\u00e9 komplik\u00e1cie, napr\u00edklad poruchy sp\u00e1nku \u010di astmu, ale aj v\u00fdrazn\u00e9 ekonomick\u00e9 straty. V Japonsku v \u010dase vrcholnej pe\u013eovej sez\u00f3ny dosahuj\u00fa pod\u013ea odhadov ekonomick\u00e9 v\u00fdpadky sp\u00f4soben\u00e9 chorobami a\u017e 1,6 miliardy dol\u00e1rov denne, a to kv\u00f4li ni\u017e\u0161ej produktivite aj poklesu spotreby.<\/p>\n

Kore\u0148 probl\u00e9mu v minulosti<\/p>\n

Mas\u00edvna v\u00fdsadba stromov nasledovala v Japonsku po druhej svetovej vojne, kedy boli rozsiahle lesn\u00e9 plochy vyr\u00faban\u00e9 z d\u00f4vodu nedostatku pal\u00edv. Vl\u00e1da vtedy zvolila r\u00fdchlo rast\u00face druhy ur\u010den\u00e9 na bud\u00face vyu\u017eitie v stavebn\u00edctve. Pe\u013e pr\u00e1ve z t\u00fdchto stromov, ktor\u00e9 ho \u010dasto uvo\u013e\u0148uj\u00fa naraz, je zodpovedn\u00fd za v\u00e4\u010d\u0161inu sez\u00f3nnych alergi\u00ed v Japonsku. Stromy navy\u0161e po dov\u0155\u0161en\u00ed veku 30 rokov uvo\u013e\u0148uj\u00fa \u010doraz viac pe\u013eu a probl\u00e9m sa tak zhor\u0161uje.<\/p>\n

Pl\u00e1n na zmenu situ\u00e1cie<\/p>\n

Japonsk\u00e1 vl\u00e1da ozna\u010dila v roku 2023 pe\u013eov\u00e9 alergie za celospolo\u010densk\u00fd probl\u00e9m a stanovila cie\u013e zn\u00ed\u017ei\u0165 mno\u017estvo pe\u013eu po\u010das 30 rokov o polovicu. Do roku 2033 chce obmedzi\u0165 plochu lesov s vysoko pe\u013eov\u00fdmi c\u00e9drami o p\u00e4tinu. S\u00fa\u010dasne podporuje obnovu prirodzenej\u0161\u00edch zmie\u0161an\u00fdch lesov, ktor\u00e9 maj\u00fa by\u0165 odolnej\u0161ie vo\u010di klimatick\u00fdm zmen\u00e1m a pr\u00edrodn\u00fdm katastrof\u00e1m.<\/p>\n

Niektor\u00e9 mest\u00e1 u\u017e niektor\u00e9 podobn\u00e9 projekty realizuj\u00fa. Napr\u00edklad Kobe postupne men\u00ed \u010dasti plant\u00e1\u017e\u00ed na listnat\u00e9 lesy a pod\u013ea miestnych \u00faradov sa do oblast\u00ed v\u010faka tomu r\u00fdchlo vracaj\u00fa p\u00f4vodn\u00e9 \u017eivo\u010d\u00edchy. Drevo z vyr\u00faban\u00fdch stromov sa vyu\u017e\u00edva napr\u00edklad na v\u00fdrobu n\u00e1bytku alebo ako palivo.<\/p>\n

Odborn\u00edci v\u0161ak upozor\u0148uj\u00fa, \u017ee premena japonsk\u00fdch lesov bude dlh\u00fd a n\u00e1kladn\u00fd proces. Krajina patr\u00ed k najviac zalesnen\u00fdm priemyseln\u00fdm \u0161t\u00e1tom sveta, jej rozlohu pokr\u00fdvaj\u00fa lesy z asi 68 percent, z \u010doho tretinu tvoria plant\u00e1\u017ee sugi a hinoki. Situ\u00e1ciu navy\u0161e komplikuje klimatick\u00e1 zmena, ktor\u00e1 sp\u00f4sobuje skor\u0161\u00ed n\u00e1stup pe\u013eovej sez\u00f3ny a jej celkov\u00e9 pred\u013a\u017eenie. Japonsko tento rok zaznamenalo najskor\u0161\u00ed za\u010diatok \u0161\u00edrenia pe\u013eu v hist\u00f3rii merania.<\/p>\n","protected":false},"excerpt":{"rendered":"TOKIO – Japonsko \u010del\u00ed rozsiahlej vlne alergi\u00ed sp\u00f4soben\u00fdch pe\u013eom, za ktor\u00fa pod\u013ea odborn\u00edkov m\u00f4\u017ee povojnov\u00e1 lesn\u00edcka politika z…\n","protected":false},"author":2,"featured_media":81385,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[8],"tags":[9005,33,24356,6696,43,40,42,36,50,49,48,463],"class_list":["post-81384","post","type-post","status-publish","format-standard","has-post-thumbnail","category-svet","tag-japonsko","tag-news","tag-pel","tag-priroda","tag-sk","tag-slovak","tag-slovencina","tag-spravy","tag-svet","tag-world","tag-world-news","tag-zdravie"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@sk\/116646311555756247","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/81384","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/comments?post=81384"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/81384\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media\/81385"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media?parent=81384"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/categories?post=81384"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/tags?post=81384"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
