Ekupheleni kohambo lwethu, masibuyele kwisifundo esichazwe kwiphepha lokuqala kwisahluko sokuqala sale ncwadi. UJoshua Blumenstock, uGabriel Cadamuro, noRobert On (2015) badibanisa idatha yeefowuni eneenkcukacha ezivela kwii-1.5 million zabantu abaneenkcukacha zesaveli ezivela kubantu abangaba ngu-1 000 ukwenzela ukuba baqikelele ukuhanjiswa kwendawo yobutyebi eRwanda. Uqikelelo lwazo lwalufana nalabo abavela kwi-Survey and Demographic Survey, imilinganiselo yegolide yokuhlola kumazwe asakhulayo, kodwa indlela yabo yayingama-10 ngokukhawuleza kunye namaxesha angama-50 angabizi. Ezi ziqikelelo ngokukhawuleza ngokukhawuleza kwaye ezincinci azipheli ngokwabo, ziyindlela yokuphelisa, ukudala amathuba amatsha kubaphandi, oorhulumente kunye neenkampani.
