Kutemwa kwemasango kuri kuwedzera. Mapapu egirinhi epasi ari kutemwa kuti atore ivhu kune zvimwe zvinangwa. Maererano nokumwe kufungidzira, tinorasikirwa nemahekita mamiriyoni 7,3 esango gore negore, akada kuenzana nenyika yePanama.
Вizvi zvingori zvinhu zvishoma
- Inenge hafu yemasango epasi anonaya mvura yakawanda akatoparara
- Parizvino, masango anofukidza chikamu che30% chenyika yose.
- Kutemwa kwemasango kunowedzera gore negore pasi rose carbon dioxide emissions ne6-12%
- Maminiti ese, sango rakakura 36 nhandare dzenhabvu rinonyangarika paNyika.
Tiri kurasikirwa nemasango kupi?
Kutemwa kwemasango kunoitika pasi rose, asi masango anonaya mvura yakawanda ndiwo anonyanya kukanganiswa. NASA inofanotaura kuti kana chiyero chemazuva ano chekuparadzwa kwemasango chikaramba chiripo, masango emvura anogona kupera zvachose mumakore zana. Nyika dzakadai seBrazil, Indonesia, Thailand, Congo nedzimwe nzvimbo dzeAfrica, uye dzimwe nzvimbo dzeEastern Europe dzichakanganiswa. Ngozi huru inotyisidzira Indonesia. Kubva muzana ramakore rapfuura, nyika iyi yakarasikirwa nemahekita anosvika miriyoni gumi nemashanu esango, sekureva kweUniversity yeMaryland USA neWorld Resources Institute.
Uye nepo kutemwa kwemasango kwakawedzera mumakore 50 apfuura, chinetso chacho chinodzokera kumashure zvikuru. Semuenzaniso, 90% yemasango ekutanga eUnited States akaparadzwa kubva kuma1600. World Resources Institute inotaura kuti masango makuru akararama kusvika pamwero mukuru muCanada, Alaska, Russia, uye Northwest Amazon.
Zvinokonzera kutemwa kwemasango
Pane zvikonzero zvakawanda zvakadaro. Maererano neshumo reWWF, hafu yemiti yakabviswa musango zvisiri pamutemo inoshandiswa sehuni.
Kazhinji, masango anopiswa kana kutemwa. Nzira idzi dzinoita kuti ivhu rirambe risingabereki.
Vanamazvikokota vezvemasango vanodana kutema zvakajeka “kukuvadzwa kwezvakatipoteredza kusina kuenzana nemasikirwo, kunze, zvichida, kuputika kukuru kwegomo rinoputika”
Kupisa sango kunogona kuitwa nekukurumidza kana kunonoka michina. Madota emiti yakatsva anopa zvokudya zvemiti kwenguva yakati. Kana ivhu rapera uye zvinomera zvaparara, varimi vanongotamira kune imwe nzvimbo uye basa rinotanga patsva.
Kutemwa kwemasango uye kuchinja kwemamiriro ekunze
Kutemwa kwemasango kunozivikanwa sechimwe chezvikonzero zviri kukonzera kudziya kwepasi. Dambudziko #1 - Kutemwa kwemasango kunokanganisa pasi rose kabhoni. Mamorekuru egasi anotora thermal infrared radiation anonzi greenhouse gases. Kuunganidzwa kwemagasi akawanda egreenhouse kunokonzera kuchinja kwemamiriro ekunze. Nehurombo, okisijeni, iyo iri yechipiri gasi rakawandisa mumhepo yedu, haitore kupisa kwemwaranzi ye infrared pamwe nemagasi egreenhouse. Kune rumwe rutivi, nzvimbo dzakasvibirira dzinobatsira kurwisa magasi egreenhouse. Kune rumwe rutivi, maererano neGreenpeace, gore negore 300 mabhiriyoni ematani e carbon anobudiswa mumhoteredzo nekuda kwekupisa kwehuni sehuni.
handiro gasi regreenhouse chete rine chekuita nekutema miti. zvakare ndewechikamu ichi. Kukanganisa kwekuparadzwa kwemasango pakutsinhana kwemhute yemvura necarbon dioxide pakati pemhepo yakapoteredza pasi nepamusoro penyika ndiro dambudziko guru remamiriro ekunze nhasi.
Kutemwa kwemasango kwakaderedza kuyerera kwepasi rose kubva pasi ne4%, maererano neongororo yakabudiswa neUS National Academy of Sciences. Kunyangwe kushanduka kudiki kwakadaro mukuyerera kwemhute kunogona kukanganisa mamiriro ekunze emamiriro ekunze uye kuchinja mamiriro ekunze aripo.
Mimwe migumisiro yekuparadzwa kwemasango
Sango igadziriro yezvipenyu yakaoma kunzwisisa inotapura zvinenge zvipenyu zvose zviri panyika. Kubvisa sango kubva muketani iyi kwakafanana nekuparadza kuenzana kwezvisikwa munharaunda uye pasi rose.
National Geographic inoti chikamu che70% chezvirimwa nemhuka zvepasi zvinogara mumasango, uye kutemwa kwazvo kwemasango kunoita kuti vanhu varasikirwe nepekugara. Migumisiro yakaipa inowanikwawo nehuwandu hwevagari vemo, iyo inobatanidzwa mukuunganidza zvokudya zvemiti yesango nekuvhima.
Miti inoita basa rinokosha mukutenderera kwemvura. Dzinokweva kunaya kwemvura uye dzinobudisa mhute yemvura mumhepo. Miti inoderedza kusvibiswa nekuteya tsvina inoyerera, maererano neNorth Carolina State University. Mugomba reAmazon, inopfuura hafu yemvura mune ecosystem inouya kuburikidza nezvirimwa, maererano neNational Geographic Society.
Midzi yemiti yakaita sezvitsigiso. Pasina sango, ivhu rinoshambidzwa nyore nyore kana kuputika, izvo zvinokanganisa zvinomera. Masayendisiti anofungidzira kuti chikamu chimwe muzvitatu chevhu rinorimwa pasi rose chakarasika nokutemwa kwemasango kubvira kuma1960. Panzvimbo peyaimbova masango, zvirimwa zvakaita sekofi, soya bhinzi nemichindwe zvinodyarwa. Kudyara mhando idzi kunoita kuti ivhu riwedzere kukukurwa nekuda kwemidzi midiki yezvirimwa izvi. Mamiriro ezvinhu neHaiti neDominican Republic anoratidza. Nyika mbiri idzi dzinogovana chitsuwa chimwe chete, asi Haiti ine sango shoma shoma. Nekuda kweizvozvo, Haiti iri kusangana nematambudziko akaita sekukukurwa kwevhu, mafashamu uye kukoromoka kwevhu.
Kupikisa kutemwa kwemasango
Vakawanda vanotenda kuti miti yakawanda inofanira kudyarwa kugadzirisa dambudziko racho. Kudyara kunogona kuderedza kukuvadzwa kunokonzerwa nekutema miti, asi hakuzogadzirise mamiriro acho mubud.
Mukuwedzera pakusimazve miti, mamwe mazano anoshandiswa.
Global Forest Watch yakatanga chirongwa chekurwisa kutemwa kwemasango kuburikidza nekuziva. Sangano rinoshandisa satellite tekinoroji, yakavhurika data uye crowdsourcing kuona nekudzivirira kutemwa kwemasango. Nharaunda yavo yepamhepo inokokawo vanhu kuti vagovane zvavanosangana nazvo - ndezvipi zvakaipa zvavakasangana nazvo nekuda kwekutsakatika kwesango.
