Isu tinowanzo funga nezvevhu rine hutano sekunyorova uye kusunungurwa nehuwandu hukuru hwezvinhu zvejekisiki. Asi kana zvirongwa zvepasi zviri mumamiriro ekunze akaomarara, iyo yekuwedzera manyuchi ichatanga kuita sei kukurumidza kuita uye ichave iri nani kubatsirwa?
Mhinduro yekupindura kwenhengo dzeNhengo dzeAmerican nzanga, avo vakaenda kunzvimbo dzakaoma reTexas kuti vaedze manyowa sekudyisa.
"Tinoziva kuti kusikwa kwemafuro ekukura kwemombe kunogona kubatsira kudzivirira uye kudzoreredza zvimiro zvekurima zvakanyanya," anodaro Lindsay Slotter, nhengo yeAmerican Society Science Science .
Slotter inotsanangura hutano hwakawanda sekugona kwekugona kwekurarama ivhu ecosystem yekuita mabasa mazhinji anokosha. Izvi zvinosanganisira kutenderera kwezvivakwa, kuchengetwa uye kucheneswa kwemvura, kubatsira zvirimwa nemhuka uye zvimwe zvakawanda.
Uyu "rarama" chikamu chine hutachiona dzakasiyana siyana vanoita basa. Semuenzaniso, ivo vanoparadzira zvakafanana manyowa kuitira kuti zvinovaka muviri zvirimo mune iyo ivhu.
"Kuwedzera manyowa kunogona kuve nechokwadi chekuwedzera kwehuwandu hwezvinhu zvekuisa zvinhu zvevhu, kureva kuti, kugadzira nzvimbo yakasimba yebasa rakakura uye kutenderera kwevakadzi," inotsanangura slotter.
Mukudzidza kwake, masayendisiti akaisa mari shoma yemhando mbiri dzezvikamu zviviri: chero huswa hwakaiswa nguva nenguva, kana musanganiswa weuswa uye nemakumbo pasina kudya.
Kazhinji, vakawana kuti manyowa anobatsira kuwedzera zvirimo kabhoni carbon muvhu uye nhamba yehupfumi muvhu - mbiri yakakosha ivhu rine hutano.
Kuti uone shanduko, zvakatora gore nehafu, kunyangwe, maererano nevatsvagiri, hapana chinhu chinoshamisa.
"Izvi zvinotiudza kuti kunyange chidiki diki chemapombi chakawedzerwa chinogona kutora nguva yakareba kuti titore chinhu chevhu chevhu, asi tsika iyi inobatsira," inotsanangura slother.
"Isu tinofunga izvi, nekuda kwesimba remamiriro ezvinhu akaomarara muchidzidzo chegore, uko mashoma egore negore, mahutachiona haakwanise kushanda nekukurumidza uye akamanikidzwa kuridza mhere pasina mvura isina mvura isina mvura isina mvura isina mvura isina mvura isina mvura. Zvakangodaro, isu takagamuchira kubvuma kuburitsa zvakananga zvinovaka muviri kubva kujekisiti zvinhu zviri muchimiro chinogona kushandisa zvidyarwa, uye zvakare kurasa izvi zvakasara kuti vagadzire chinhu chevhu. Uye iyi inzira yekuvandudza marongero ekurima, "akawedzera.
Matanho anotevera ari muiri basa anosanganisira mhinduro kumubvunzo wekuti kuchave nekuwedzera kwekunyepedzera kana kuwanda kwenhamba zviri nani? Maitiro ekudiridza kana kuwedzerwa kweNitrogen fetilizers achikurumidza?
"Tinoda kumwe kutsvagisa zano rekuratidzira nekukurumidza hutano hwevhu. Inobatsira varimi kuchengetedza mari pazvinhu zvinovaka muviri uye zvinowedzera, inochengetedza mvura uye inochengetedza kurwisa kusvibiswa kwevhu, "akagumisa.
