USinikiwe Khumalo, othweswe iziqu eNyuvesi yaKwaZulu-Natal, useqhamuke indlela entsha yokuguqula indle yabantu ibe umquba ophephile futhi unemsoco odingwa yizitshalo. Ucwaningo lwakhe lugxile ekuhlanganiseni ndawonye udaka lwendle oluchithiwe nemfucuza yasengadini, ukuphambukisa ngempumelelo amathani angaphezu kuka-15 emfucumfucu ezindaweni zokulahla imfucuza zendawo kanye nezindawo zokuhlanza amanzi angcolile.
Indlela kaKhumalo yokwenza umquba ikhombise imiphumela encomekayo, ikakhulukazi ekukhuthazeni ukukhula kwezithombo ze-cucumber. Ezivivinyweni, umquba wakhe wenze kangcono kuneminye imikhiqizo yezentengiselwano, unikeza enye indlela ephumelelayo neqhubekayo yokunothisa umhlabathi. Indlela yakhe ayigcini nje ngokuthuthukisa ukuvunda komhlabathi kodwa futhi inikeza isisombululo esisebenzayo ezinseleleni ezikhulayo zokulawulwa kwemfucuza eNingizimu Afrika.
Ngokugqugquzelwa ukukhulela kwakhe emphakathini owawuthembele ekulimeni, uKhumalo waqala ukuthanda ezolimo esemncane. Manje uhlela ukwenza iziqu ze-PhD, ehlose ukuqhubeka nokuphenya ukuthi ukwenza umquba wemfucuza yabantu kunganciphisa kanjani ukukhishwa kwemfucumfucu futhi kuzuze imvelo.
Umsebenzi wakhe ugqamisa ukuphambana okunamandla kwezolimo olusimeme kanye nokuphathwa kwemfucuza okusha. Inikeza imodeli ethembisayo engamukelwa ezweni lonke, ibhekane nakho kokubili ukucekelwa phansi kwemvelo kanye nokuvikeleka kokudla. Ngokuphendula imfucuza ibe yinsiza, uKhumalo utshala imbewu yenguquko yekusasa elisimeme neliqinile.
