Kuramba uchitarisa "kushaikwa kwemvura" mumiti kwakakosha zvikuru munzvimbo dzakaoma uye kwagara kuchiitwa nekuyera hunyoro hwevhu kana kugadzira mamodheru e evapotranspiration kuti uverenge huwandu hwekubuda kwemvura pamusoro uye kupfuudzwa kwemiti. Asi pane mukana wekuvandudza kushanda zvakanaka kwemvura kuburikidza netekinoroji itsva iyo inonyatsoona kana zvirimwa zvichida kudiridza.
Vaongorori vakasarudza mashizha matanhatu asina kurongeka akaonekwa zvakananga kune chiedza uye vakaisa masensa emashizha paari, vachidzivirira mitsipa mikuru nemipendero. Vakanyora zviyero mumaminitsi mashanu ega ega.
Tsvagiridzo iyi inogona kutungamira mukugadzirwa kwehurongwa umo masensa ekuongorora mashizha anotumira ruzivo rwakarurama rwehunyoro hwezvirimwa kuchikamu chikuru chiri mumunda, icho chinozotaurirana nenguva chaiyo nehurongwa hwekudiridza kuzvirimwa zvinodiridza.
Kuchinja kwezuva nezuva pakukora kwemashizha kwaive kudiki uye hapana shanduko huru dzakaonekwa zuva nezuva sezvo mwero wehunyoro hwevhu waichinja kubva pakakwirira kuenda pakuoma. Zvisinei, apo hunyoro hwevhu hwaive pasi pehuoma, kuchinja kwekukora kwemashizha kwaive pachena kusvika ukobvu hwemashizha hwagadzikana mukati memazuva maviri ekupedzisira ekuyedza apo huwandu hwehunyoro hwasvika 5%. Kukwanisa kwemashizha kuchengeta simba, uko kunoyera kugona kwemashizha kuchengetedza simba, kunoramba kwakafanana panguva yerima uye kunowedzera nekukurumidza munguva yechiedza. Izvi zvinoreva kuti kugona kunoratidza kushanda kwe photosynthesis. Kana hunyoro hwevhu huri pasi pehunosvava, kuchinja kwesimba rezuva nezuva kunoderera uye kunomira zvachose kana hunyoro hwevhu huchidzikira pasi pe11%, zvichiratidza kuti mhedzisiro yekumanikidzwa kwemvura pasimba inoonekwa kuburikidza nemhedzisiro yayo pa photosynthesis.
"Ukobvu hwepepa hwakaita sebharumu—inowedzera nekuda kwemvura uye kuderera nekuda kwekushaikwa kwemvura kana kupera simba mumuviri,""Zvichitaurwa zviri nyore, kugona kwemashizha kunochinja nekuchinja kwemamiriro emvura yechirimwa uye chiedza chekunze. Saka, kuongororwa kweukobvu hwemashizha nekuchinja kwesimba rechirimwa kunogona kuratidza mamiriro emvura muchirimwa - tsime rekumanikidzwa. »
