Women in nonfarm rural employment: implications on the social and economic empowerment of rural women in Uganda

July-September 2021

Nonfarm employment is an increasing form of employment in rural areas in Sub-Saharan Africa. This is partly because many of the workers in developing countries especially in Sub-Saharan Africa are self-employed workers.  Most women in Uganda do not own land since customary land ownership system deprives women of owning land. This has pushed women to nonfarm employment in urban areas, semi-rural, and rural areas....
