Tsiku la Mitengo

tsiku la mtengo

Mitengo ndi anthu akale kwambiri padziko lapansi. Iwo ali ndi udindo wotulutsa mpweya ndi kusintha mpweya woipa (CO2), motero amachepetsa kutentha kwa mpweya mumlengalenga. The Tsiku la Mitengo limatikumbutsa kufunika koteteza madera a nkhalango kuti pakhale zamoyo zonse padziko lapansili.

Chifukwa chake, tipereka nkhaniyi kuti tikuuzeni zonse zomwe muyenera kudziwa zokhudza Tsiku la Arbor ndi kufunika kwake.

Chifukwa chiyani pali Tsiku la Arbor?

nkhalango

Tiyenera kusiyanitsa Tsiku la Arbor (June 28) ndi International Day of Forests pa March 21. Tsiku lina ndi logwirizana kwambiri ndi kutsindika kufunika kwa mitengo ndi nkhalango, ndi cholinga chodziwitsa anthu za kufunika koteteza madera a nkhalango kuonetsetsa kuti zamoyo zikukhalapo.

Mitengo imakhala ndi ntchito zambiri zomwe zimagwira nawo ntchito zachilengedwe. Kuchokera pakupanga okosijeni mpaka kukhala mthandizi wathu wabwino kwambiri pothana ndi vuto la nyengo. Ndi mitengo imene ili maziko a kupulumuka kwa zolengedwa za padziko lapansi. Ndiwo malo abwino kwambiri achilengedwe, kumene mitundu yambirimbiri ya nyama ndi zomera imakhala.

Kuonjezera apo, mitengo imatithandiza kulamulira kayendedwe ka kayendedwe ka madzi, motero kuchepetsa ngozi ya kusefukira kwa madzi, ndipo imakhala gwero la zipangizo zopangira mankhwala ndi zinthu zina zachilengedwe. Komabe, zochita za anthu zawononga pafupifupi 78% ya nkhalango zomwe zidalipo padziko lapansi ndi 22% yotsala yakhudzidwa ndi kudula mitengo. Kuwonongeka kwa chilengedwe kwa malowa sikumangokhudza mwachindunji chilengedwe chathu ndikutulutsa mpweya woipa m'mlengalenga, komanso kumakhudza zamoyo zathu zosiyanasiyana, komanso kuyika pangozi zamoyo zambiri.

Izi zidapangitsa kuti bungwe la United Nations Decade for Ecosystem Restoration likhazikitsidwe mu 2021, lomwe likufuna kuti m'zaka khumi zikubwerazi zichitike pofuna kupewa kuwonongeka kosasinthika kwachilengedwe.

Ngati pali Tsiku la Arbor, ndi mawu akuti m'pofunika kuthetsa vutoli, ndipo titha kugwirira ntchito limodzi kuonetsetsa chitetezo cha chilengedwe. Sweden ndi dziko loyamba kuchita chikondwererochi. Adachita izi mu 1840 kuti adziwitse za ntchito yofunika yomwe mitengo ili nayo pochepetsa kuwononga chilengedwe, kuteteza nthaka komanso kupeza chitukuko chokhazikika.

Kodi nkhalango ingatenge mpweya wotani wochuluka bwanji?

kuteteza mitengo

Kuti tidziwe kuchuluka kwa carbon dioxide yomwe nkhalangoyi imatengera, choyamba tiyenera kupenda mitengo yomwe imapangidwa. Kafukufuku waposachedwapa wochitidwa ndi wofufuza wina wa pa yunivesite ya Seville anasonyeza kuti mtengo wapaini wa Aleppo ndi umodzi mwa mitengo imene imamwa mpweya woipa kwambiri. Akuti paini wokhwima wa Aleppo amatha kuyamwa mpaka matani 50 a carbon dioxide pachaka.

Mwa kuyankhula kwina, chitsanzo chokhwima chamtunduwu chimatha kuyamwa mpweya wopangidwa ndi magalimoto 30 apakati omwe amayenda makilomita 10.000 pachaka. Chilumba cha Iberia ndi malo abwino kwambiri kuti mitengoyi ikule, motero nkhalango ya paini ili ndi kuthekera kwakukulu kothira madzi a carbon.

Chifukwa cha kuchuluka kwa zamoyo zosiyanasiyana, chiwerengero chachikulu cha CO2 kumira ndi nkhalango namwali. Nkhalango yamitundu yosasinthika, yakale komanso yachilengedwe, momwe mulibe umboni woonekeratu wa zochita za anthu, komanso momwe chilengedwe chimasinthiratu. Nkhalango zakudazi ndi magwero a kayendetsedwe ka nyengo zachepetsedwa chifukwa cha kulowererapo kwa anthu.

Tsiku la Arbor kulemekeza ogwirizana nawo motsutsana ndi kusintha kwa nyengo

kufunika kwa tsiku la mtengo

Nkhalango zazikulu zisanu ndi ziwiri zomaliza zapadziko lapansi ndi izi:

  • Nkhalango ya Amazon
  • Nkhalango ya ku Southeast Asia
  • Nkhalango zamvula zapakati pa Africa
  • Nkhalango zozizira za South America
  • Nkhalango zoyambira ku North America ndi Canada
  • Nkhalango zomaliza za ku Europe
  • Nkhalango za taiga ya ku Siberia

Mofanana ndi nyanja, kuteteza nkhalango kumatanthauza kuteteza njira yamphamvu kwambiri yotengera ndi kusunga mpweya woipa. Luso lake ndi lodabwitsa. Akuti mtengo umasunga pafupifupi 22 kg ya carbon dioxide pachaka. Nkhalango yamvula imasunga matani 250 biliyoni a carbon dioxide m’mitengo yokha, zomwe zikufanana ndi zaka 90 za mpweya wapadziko lonse lapansi. Nkhalango za ku Ulaya zimapatula pafupifupi 10% ya mpweya wowonjezera kutentha wa European Union. Ku Spain, nkhalango zimakonza matani a carbon pa hekitala imodzi pachaka.

Komabe, kafukufuku angapo tsopano akuwonetsa kuti ngati sitisintha machitidwe athu ena okonda zachilengedwe, luso limeneli lachilengedwe la mitengo likhoza kuchepetsedwa. Mutha kuchoka pakukhala mthandizi wathu mukukumana ndi zovuta zanyengo kupita kwa m'modzi wa adani athu. Pachifukwa ichi, ndikofunikira kupeza njira zokhazikika zomwe zimatithandiza kulinganiza kukonzanso nkhalango, kuletsa kudula mitengo mwachisawawa komanso kuthetsa kudula mitengo mosaloledwa.

Zifukwa zobzala mitengo

Mitengo imagwira ntchito yofunika kwambiri poteteza chilengedwe:

  • Amatulutsa mpweya ndikusintha mpweya woipa (CO2) kukhala biomass, motero kuchepetsa greenhouse effect.
  • Iwo ndi owongolera a hydrological cycle ndipo amathandizira kupewa kusefukira kwa madzi.
  • Amaletsa kukokoloka kwa nthaka ndipo amakondera chitukuko cha ulimi.
  • Amapanga malo okhalamo zomera, mbalame, zoyamwitsa, zokwawa ndi amphibians.
  • M'madera a nkhalango, zimathandizira kupanga malo a chinyezi.
  • Amathandizira kuwongolera nyengo komanso kuchepetsa kusinthika kwanyengo, komwe kumachitika makamaka ndi anthu.
  • Ndiwo gwero la zipangizo zopangira mankhwala, chakudya, mapepala, mafuta (nkhuni ndi malasha), ulusi ndi zinthu zina zachilengedwe (monga nkhuni, utomoni ndi labala).

Zina mwazokonda zamitengo ndi izi:

  • Malinga ndi kafukufuku waposachedwapa (wofalitsidwa ndi Journal of Sustainable Forestry), pali mitundu ya mitengo ya 60,065 pa dziko lathu lapansi.
  • Kutengera ndi mitundu, lMitengo imakula bwino ikafika zaka 40 kapena 50.
  • M'madera ozizira kapena madera, amaweta makoswe ndi mbalame.
  • Padziko lonse lapansi, pafupifupi 78% ya nkhalango zomwe zidawonongedwa ndi anthu ndipo 22% yotsala yakhudzidwa ndi kudula mitengo.
  • 12% ya nkhalango zapadziko lonse lapansi zasankhidwa kuti ziteteze mitundu yosiyanasiyana ya zachilengedwe.
  • Akuti nkhalangoyi imapanga malo osungiramo mpweya wofunika kwambiri, omwe amasonkhanitsa pafupifupi ma gigatoni 289 a chinthu ichi.
  • Kupatula ku Antarctica ndi Greenland, amatenga malo ambiri, omwe amawerengera 28,5% ya dziko lapansi.
  • Theka la nkhalango zapadziko lonse lapansi zili m'madera otentha ndipo zina zonse zili m'madera ofunda komanso otsetsereka.

Ndikukhulupirira kuti ndi chidziwitsochi mutha kuphunzira zambiri za Tsiku la Arbor ndi kufunika kwake.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
