Ngombulelo kwi-thesis egqitywe kwiYunivesithi yaseAalto, ihlathi lamalahle lakhiwa eKerava
Kwithisisi yomakhi wendalo esandula ukugqitywa, uhlobo olutsha lwehlathi lehlathi - ihlathi lekhabhoni - lakhiwa kwindawo yedolophu yaseKerava, esebenza njenge-carbon sink kwaye kwangaxeshanye ivelisa ezinye izibonelelo ze-ecosystem.
Ukutshintsha kwemozulu ngomnye wemingeni emikhulu kule nkulungwane, yiyo loo nto ngoku kukho ingxoxo yoluntu edlamkileyo malunga nokomeleza iisinki zekhabhoni zendalo, njengemithi kunye nezityalo.
Ingxoxo ye-carbon sink ngokuqhelekileyo igxile emahlathini kunye nokugcina kunye nokwandisa indawo yehlathi ngaphandle kwezixeko. Uthweswe isidanga somyili we-landscape Anna Pursiainen nangona kunjalo, ubonisa kwithisisi yakhe ukuba ekukhanyeni kwezifundo zamva nje, iipaki kunye neendawo eziluhlaza kumaziko oluntu nazo zidlala indima enkulu ngokuphawulekayo ekuthathweni kwekhabhoni.
Iindawo eziluhlaza ezinamaleko amaninzi kunye neentlobo ezininzi zezixeko zibalulekile ekwakheni i-ecosystem
Kwizixeko ezininzi, unokufumana amahlathi adityanisiweyo njengeentsalela zemimandla yamahlathi angaphambili, kunye neendawo eziluhlaza ezinotyani obahlukeneyo. Loo mahlathi kunye neendawo eziluhlaza zibophelela kakuhle ikharbon diokside kwaye zixhasa ubume bendalo.
Injongo yethisisi yediploma kaPursiainen kukufunda ingcali ngezityalo yaseJapan kunye nenzululwazi ngezityalo U-Akira Miyawaki naye Indlela ye-microforest ephuhliswe kwi-70s kwaye iyasebenza eFinland, ngakumbi ukusuka kwindawo yokujonga i-carbon sequestration. Kumsebenzi wakhe, uPursiainen uphuhlisa imigaqo yokuyila ihlathi lamalahle, elisetyenziswa kwihlathi lamalahle eKerava.
Umsebenzi wediploma wenziwe njengenxalenye yeprojekthi ye-Co-Carbon ephanda uhlaza lwasedolophini ngobulumko bekhabhoni. Isixeko saseKerava siye sathatha inxaxheba kwisicwangciso se-diploma ithisisi ngokuqaphela ihlathi lekhabhoni.
Yintoni ihlathi lamalahle?
I-Hiilimetsänen luhlobo olutsha lwehlathi elinokwakhiwa kwindawo yasezidolophini yaseFinnish. I-Hiilimetsänen yakhiwe ngendlela yokuba iintlobo ezininzi zemithi ekhethiweyo kunye nezihlahla zityalwe ngokuxineneyo kwindawo encinci. Kwindawo yobukhulu bemitha yesikwere, ezintathu iitaina zityalwe.
Iintlobo eziza kutyalwa zikhethwa kumahlathi ajikelezileyo kunye neendawo eziluhlaza. Ngale ndlela, zombini iintlobo zehlathi lendalo kunye neentlobo zepaki ezihonjisiweyo zibandakanyiwe. Imithi etyalwe ngokuxineneyo ikhula ngokukhawuleza ifuna ukukhanya. Ngale ndlela, ihlathi elifana nendalo lifumaneka kwisiqingatha sexesha kunesiqhelo.
Libekwe phi ihlathi lamalahle eKerava?
Ihlathi lamalahle eKerava lakhiwe kwindawo yaseKerava Kivisilla ekudibaneni kwePorvoontie kunye neKytömaantie. Iintlobo ezikhethiweyo kwihlathi lamalahle ngumxube wemithi, izihlahla kunye nezithole zehlathi. Ekukhethweni kweentlobo, kugxininiswe kwiintlobo ezikhula ngokukhawuleza kunye nefuthe lobuhle, njengemibala ye-trunk okanye amaqabunga.
Injongo kukuba ukutyalwa kube kwinqanaba elihle lokukhula ngexesha leNew Era Construction Festival (URF) eququzelelwe ngokuhlonipha i-Kerava 100 anniversary. Umnyhadala ubonisa ukwakhiwa okuzinzileyo, ukuphila kunye nendlela yokuphila kwindawo eluhlaza ye-Kerava manor ukusuka nge-26.7 kaJulayi ukuya kwi-7.8.2024 ka-Agasti ka-XNUMX.
Hiilimetsäsen inomlinganiselo osebenzayo kunye nendalo
Amahlathi amancinane abonelela ngezinto ezahlukeneyo ngokuxhasa imeko-bume yasezidolophini ekudambiseni utshintsho lwemozulu, ngakumbi kwizixeko ezixinana. Imekobume yedolophu eluhlaza nayo ifundwe ukuba ibe neenzuzo zempilo.
Amahlathi amalahle anokusetyenziswa njengenxalenye yeepaki kunye nezikwere zedolophu kwaye anokubekwa nakwiibhloko zokuhlala. Ngenxa yomkhwa walo wokukhula, ihlathi lamalahle liyakwazi ukulungelelaniswa nakwindawo emxinwa njengento yokwahlula okanye inokunyuswa kwiindawo ezinkulu. Amahlathi amalahle yenye indawo yodidi olunye lwemithi emiqolo yasesitalatweni kwakunye nezothutho kunye neendawo zamahlathi zokhuseleko lwemizi-mveliso.
I-Hilimetsäse ikwanombono wezemfundo ngokusingqongileyo, njengoko ivula ukubaluleka kokuthathwa kwekhabhoni kunye nemithi kubahlali basezidolophini. Hiilimetsäsen inamandla okuphuhlisa ibe yenye yeentlobo zeendawo zokuhlala kwizisombululo ezisekelwe kwindalo.

Ukucwangciswa kwehlathi le-Kerava charcoal kwaqala ehlobo lika-2022. Umsebenzi wokutyala wenziwa entwasahlobo ka-2023.
Hiilimetsänen e Kerava kaThixo Kivisilla.
