Ukuqapha okuqhubekayo "kokucindezeleka kwamanzi" kwezitshalo kubaluleke kakhulu ezindaweni ezomile futhi kuye kwenziwa ngokujwayelekile ngokulinganisa umswakama wenhlabathi noma ukuthuthukisa amamodeli okuhwamuka komoya ukuze kubalwe inani lokuhwamuka kwamanzi ebusweni kanye nokuhwamuka kwezitshalo. Kodwa kukhona amathuba okuthuthukisa ukusebenza kahle kwamanzi ngokusebenzisa ubuchwepheshe obusha obuzwa ngokunembile lapho izitshalo zidinga ukuniselwa.
Abacwaningi bakhethe ngokungahleliwe amaqabunga ayisithupha ayevezwe ngqo emthonjeni wokukhanya futhi bafaka izinzwa zamaqabunga kuwo, begwema imithambo emikhulu kanye nemiphetho. Baqopha izilinganiso njalo ngemizuzu emihlanu.
Lolu cwaningo lungaholela ekuthuthukisweni kohlelo lapho izinzwa zokucindezela amaqabunga zithumela khona ulwazi oluqondile lomswakama wesitshalo kuyunithi ephakathi ensimini, bese ixhumana ngesikhathi sangempela nohlelo lokunisela ezitshalweni zamanzi.
Izinguquko zansuku zonke ekujikeni kwamaqabunga zazincane futhi akukho zinguquko ezibalulekile zansuku zonke ezabonwa njengoba amazinga omswakama wenhlabathi eshintsha esuka phezulu eya endaweni yokubuna. Kodwa-ke, lapho umswakama wenhlabathi ungaphansi kwendawo yokubuna, ushintsho ekujikeni kwamaqabunga lwalubonakala kakhulu kwaze kwaba yilapho ukujiya kwamaqabunga kuzinza phakathi nezinsuku ezimbili zokugcina zokuhlola lapho okuqukethwe komswakama kufinyelela ku-5%. Umthamo, olinganisa ikhono leqabunga lokugcina amandla, uhlala ufana okungenani ngezikhathi zobumnyama futhi ukhula ngokushesha ngezikhathi zokukhanya. Lokhu kusho ukuthi umthamo uwukubonakaliswa komsebenzi we-photosynthesis. Uma umswakama wenhlabathi ungaphansi kwephuzu lokubuna, ushintsho lwemini lomthamo luyehla futhi luyeke ngokuphelele lapho umswakama wenhlabathi wehla ngaphansi kuka-11%, okubonisa ukuthi umphumela wokucindezeleka kwamanzi kumthamo ubonakala ngomphumela wawo ku-photosynthesis.
"Ubukhulu beshidi bufana nebhaluni—iyanda ngenxa yokuntuleka kwamanzi kanye nokuncipha ngenxa yokucindezeleka kwamanzi noma ukuphelelwa amanzi emzimbeni,"Kalula nje, umthamo wamaqabunga uyashintsha ngokushintsha kwesimo samanzi sesitshalo kanye nokukhanya okuzungezile. Ngakho-ke, ukuhlaziywa kobukhulu bamaqabunga kanye noshintsho kumthamo kungabonisa isimo samanzi esitshalweni - umthombo wokucindezela. »
