Komabe, m’nyengo yotentha ku South Africa, nyumba zosungiramo mafilimu zimatha kutenthedwa, zomwe zimachititsa kuti akhazikike zipangizo zozizirirapo.

Makatani onyowa amagwira ntchito popangitsa madzi kukhala nthunzi kuti atenge kutentha, pomwe mafani amazungulira mpweya, kuwonetsetsa kuti kutentha ndi chinyezi kumakhalabe m'malo oyenera mbewu.
Njira yoziziritsira imalola mbewu monga tomato, nkhaka, ndi tsabola kuti zizikula bwino ngakhale m’miyezi yotentha yachilimwe. Kutentha kumayendetsedwa bwino, mbewu zimakula mofanana komanso zathanzi, kuchepetsa chiopsezo cha kuwonongeka kwa kutentha ndi tizilombo towononga, potsirizira pake kumakulitsa ubwino ndi mpikisano wamsika wa zokolola.
Kuphatikizika kwa nyumba zosungiramo mafilimu ndi machitidwe ozizira sikungothetsa vuto la kutentha komanso kumapereka njira yowonjezereka komanso yokhazikika kwa alimi ku South Africa.
