What changes does Kumalo want to make when he returns to Ndotsheni?

The drought in Ndotsheni is a metaphor for the larger drought in South Africa itself. Causing a lack of nourishment among the people and beyond the control of its victims, the drought can be combated only through widespread improvements within South Africa and a communal effort uniting all segments of South African society. Paton bolsters the idea that Ndotsheni is merely a microcosm representing all of South Africa through Stephen Kumalo's church service, in which they pray for God to save Africa. Kumalo wants to begin with proper nourishment for his people (proper irrigation...) and a gentler, less antagonistic, relationship with whites.
