Sayansi ya nthaka

A Farmers Pride International agwirana manja ndi bungwe la   Padziko lonse lapansi 4/1000  Initiative on Dothi ndi Chitetezo Chakudya  ndipo akuyembekeza kukhala woyimilira ku Southern Africa. Tatenga chisankhochi  monga tikuona kuti n'kofunika kukonzekera m'badwo wotsatira wa interdisciplinary nthaka asayansi. Pokhapokha ndi ndalama zokwanira mu sayansi ya nthaka dziko lidzakhala ndi antchito (ophunzitsa, ofufuza, ndi oyang'anira nthaka) ofunikira kuti ateteze chinthu chosasinthikachi ndikuwonetsetsa kuti chilengedwe chili ndi thanzi komanso kupitiriza kupanga chakudya, fiber, chakudya ndi mafuta.

Ntchito yapadziko lonse "4 pa 1000", yomwe idakhazikitsidwa ndi France pa Disembala 1, 2015 ku COP 21, ili ndi mgwirizano wodzipereka wodzipereka m'maboma ndi mabungwe aboma (maboma adziko, maboma am'deralo ndi zigawo, makampani, mabungwe azamalonda, NGOs, kafukufuku. zipangizo, etc.) pansi pa ndondomeko ya Lima-Paris Action Plan (LPAP).

Cholinga cha ndondomekoyi ndikuwonetsa kuti ulimi, makamaka dothi laulimi, lingathe kutenga gawo lofunika kwambiri pazakudya komanso kusintha kwa nyengo.

Ntchito yapadziko lonse lapansi "4 pa 1000", yomwe idakhazikitsidwa ndi France pa 1 Disembala 2015 ku COP 21, imakhala ndi mgwirizano wodzipereka wodzipereka m'maboma ndi mabungwe aboma (maboma adziko, maboma am'deralo ndi zigawo, makampani, mabungwe azamalonda, ma NGO, kafukufuku. zipangizo, etc.) pansi pa ndondomeko ya Lima-Paris Action Plan (LAP).

Cholinga cha ndondomekoyi ndikuwonetsa kuti ulimi, makamaka dothi laulimi, lingathe kutenga gawo lofunika kwambiri pazakudya komanso kusintha kwa nyengo.

Mothandizidwa ndi zolembedwa zolimba zasayansi, ntchitoyi ikupempha onse ogwira nawo ntchito kuti afotokoze kapena agwiritse ntchito njira zina zosungiramo mpweya m'nthaka ndi mtundu wa machitidwe kuti akwaniritse izi (mwachitsanzo, agroecology, agroforestry, ulimi wosamalira, kasamalidwe ka malo, ndi zina zotero).

Cholinga cha ndondomekoyi ndi kulimbikitsa ogwira nawo ntchito kuti asinthe kupita ku ulimi wopindulitsa, wokhazikika, potengera kasamalidwe koyenera ka minda ndi nthaka, kupanga ntchito ndi ndalama zomwe zimapangitsa kuti chitukuko chikhale chokhazikika. The Executive Secretariat of the "4 per 1000" initiative imayendetsedwa ndi CGIAR System Organisation, bungwe lapadziko lonse lapansi lokhala ku Montpellier.

Kukula kwapachaka kwa 0,4% m'nthaka ya carbon, kapena 4 ‰ pachaka, mu nthaka yoyamba ya 30-40 masentimita, kungachepetse kwambiri CO2 ndende mumlengalenga yokhudzana ndi ntchito za anthu.

Kukula kumeneku sikuli kovomerezeka kwa dziko lililonse koma cholinga chake ndi kusonyeza kuti ngakhale kuwonjezeka pang'ono kwa carbon carbon (nthaka yaulimi, makamaka udzu ndi malo odyetserako ziweto, ndi nthaka ya m'nkhalango) n'kofunika kwambiri kuti nthaka ikhale chonde komanso ulimi ndi Zimathandizira kukwaniritsa cholinga chanthawi yayitali chochepetsera kutentha kwa +2 ° C, kupitilira pamenepo.  Mtengo wa IPCC  (Intergovernmental Panel on Climate Change) ikusonyeza kuti zotsatira za kusintha kwa nyengo ndizofunika kwambiri.

Cholinga cha "4 pa 1000" ndikuthandizira zomwe zikufunika zochepetsera mpweya wotenthetsa mpweya, padziko lonse lapansi komanso pazachuma chonse. Ndizodzifunira, zili kwa membala aliyense kuti afotokoze momwe akufuna kuthandizira kukwaniritsa zolinga. .

Onerani Vidiyo Iyi Kuti Mudziwe Zambiri
 

Zochita za anthu zimatulutsa mpweya wochuluka wa carbon dioxide (CO2) mumlengalenga, zomwe zimawonjezera kutentha kwa dziko ndikufulumizitsa kusintha kwa nyengo.

Chaka chilichonse, 30% ya carbon dioxide (CO2) imatengedwa ndi zomera chifukwa cha photosynthesis. Kenako, zomerazo zikafa ndi kuwola, zamoyo za m’nthaka, monga mabakiteriya, bowa kapena nyongolotsi za m’nthaka, zimasintha n’kukhala zinthu zachilengedwe.

Chomera chochuluka cha kaboni ichi ndi chofunikira pazakudya za anthu chifukwa chimasunga madzi,  nayitrogeni ndi phosphorous, zofunika pakukula mbewu.

Dothi lapadziko lonse lapansi lili ndi mpweya wochulukirapo ka 2 mpaka 3 kuposa mlengalenga.

Ngati mpweya wa kaboni ukuwonjezeka ndi 0,4%, kapena 4 ‰ pachaka, mu nthaka yoyamba ya 30-40 masentimita, kuwonjezeka kwapachaka kwa carbon dioxide (CO2) mumlengalenga kudzachepetsedwa kwambiri.

Izi ndi zomwe bungwe la 4 pa 1000 Initiative likunena: dothi lokhala ndi chakudya chokwanira komanso nyengo.

Kuchuluka kwa carbon mu nthaka kumathandizira ku:

  • osati kukhazikika kwa nyengo

  • komanso kuonetsetsa kuti pali chakudya chokwanira, mwachitsanzo, kupereka chakudya chokwanira

Organic zinthu mu dothi:

Zopangidwa ndi carbon, organic matter mu dothi zimagwira ntchito muzinthu zinayi zofunika za chilengedwe:

  • kukana kukokoloka kwa nthaka,  

  • kusunga madzi m'nthaka,  

  • chonde cha nthaka kwa zomera ndi  

  • nthaka zamoyo zosiyanasiyana.

Ngakhale kusintha kwakung'ono m'nthaka ya carbon pool kumakhala ndi zotsatira zazikulu pazaulimi komanso pamlingo wa mpweya wowonjezera kutentha.

Kusamalira dothi lokhala ndi mpweya wambiri, kubwezeretsa ndi kukonza minda yomwe yawonongeka  ndipo, mochuluka, kuwonjezeka kwa carbon carbon, kumagwira ntchito yofunika kwambiri pothana ndi zovuta zitatu zachitetezo cha chakudya, kusintha kwa machitidwe a chakudya ndi anthu ku kusintha kwa nyengo, ndi kuchepetsa mpweya wa anthropogenic.
