Mazuva ano munharaunda yanhasi, kunyangwe iwe uchinyatsoziva nezve nharaunda uye shanduko yemamiriro ekunze kana kwete, anenge munhu wese anoona kutema miti nekuparadza masango se chinhu chakakosha chinopa mukuwedzera mhedzisiro yeshanduko yemamiriro ekunze. Izvo zvinoitwazve mukutarisirwa kuti kuchengetedzwa uye kushandiswa kwakaringana kwemasango epasi pano kunobatsira zvakanyanya kudzikisa gasi rinokanganisa kupisa, kana kuti zvirinani kupinza kwavo mumhepo.
Chibvumirano cheParis, Yakagamuchirwa nemapato 195 kuUnited Nations Framework Convention on Climate Change mukupera kwegore rapfuura, yaive nzvimbo yekutanga yekuziva kuti masango akakosha pakurwisa shanduko yemamiriro ekunze. Masango anogara achitibatsira anotibatsira sei pakurwisa shanduko yemamiriro ekunze?
Carbon inonyura
Masango kutenderera pasirese anoita sekabhoni inonyura. Ivo "vanoshanda" kwatiri kuchengetedza magreenhouse gases mu biomass yako, marara uye nevhu. Mupiro wemasango pakurwisa shanduko yemamiriro ekunze ipfumo rinocheka kumativi maviri. Izvi zvinodaro nekuti kutemwa kwemiti nekudzikisirwa kwemasango atinokonzeresa nezviitiko zvedu zvehupfumi zvinokonzeresa pakati pe10% ne12% yezvose zvinoburitsa gasi. Ndokunge, pamwe chete nezvekurima, ivo vari vechipiri vanokonzeresa kudziya kwepasi.
Mune mamwe mazwi, masango anogona kutibatsira kupinza nekuchengetedza yakawandisa kabhoni kubva mumhepo, asi kana miti ikafa, inosunungura CO2 inobatana nezvimwe zvakasara. Nyika dzakaita seCongo, Gabon, Indonesia, Kenya, Malaysia, Mexico neSouth Korea dzakazvipira kudzikisa mweya zvinopfuura makumi maviri neshanu muzana ezviitiko zvakajairika zvezviitiko. Zvakare, inopfuura 70% yeiyi mhiko dzekuzvidira dzinosanganisira zviito zvine chekuita nemasango uye kuchengetwa kwavo kwakakodzera.
Kugona kwakanaka kweshanduko yemamiriro ekunze
Masayendisiti anoti manejimendi manejimendi manejimendi uye kutarisirwa kwakanaka kwemasango uye zvese zvakafukidzwa nemasango zvinogona kubatsira zvakanyanya mukurwisa shanduko yemamiriro ekunze. Semuenzaniso, kupa data kuti ikubatsire kuwana zano, 123 michero yemiti yakakura kwemakore gumi ivo vanogona kusevha kabhoni yakaburitswa negore rekutyaira mota.
Zano rekugona kutora zvirongwa zvebudiriro yekusimudzira muzvinhu zvemasango zvakakosha zvakanyanya kune nyika dzichiri kusimukira, sezvo huwandu hwakawanda hwekuburitsa kabhoni kubva mukutemwa kwemasango kunoitika kumaodzanyemba kwenyika. Izvi zvinonyanya nekuti miti anotemwa kuti awane nzvimbo yekurima. Mune mamwe mazwi, dondo rinokwanisa kudya. Nekurima, nyika dzakabudirira zvishoma dzinogona kuwana mari yepurazi.
Muenzaniso weiyi kushandiswa kwehuni sehuni. Inenge chetatu chemhuri pasi rese inoishandisa kubika chikafu, nepo vamwe vanhu mamiriyoni mazana manomwe nemakumi manomwe nenomwe vanoishandisa kufashaidza nekuchenesa mvura
Mazano ekuderedza kuburitsa kabhoni
Anenge 75% ematani eCO2 iyo inoburitsirwa mudenga nekucheka miti yekushandisa huni, kunobva pakubika chikafu. Makicheni mazhinji emazuva ano uye akavandudzwa anopisa huni shoma, zvichibatsira kuburitsa mashoma CO2 mumhepo. Izvi zvinopa kudzikiswa kwemweya wegreenhouse gasi mumhepo, kunyanya muAfrica nemumaruwa eLatin America.
Zviripachena kuti kiyi yekudzora chisi kusimba uye kushandiswa kwetekinoroji yazvino inobatsira kuburitsa ethanol kubva kune huni biomass. Shandisa zvigadzirwa zvehuni sezvinhu zvakasvibirira zvekuvaka. Isu tinotaura ecological kubvira nekusazvipisa vanochengetedza kabhoni yakachengetwa mukati.
