The study examined gender analysis of energy use for Rice production in north central Nigeria using a sample of 60 Rice farmers. An analysis of gender relations provides the information on the different conditions men and women face, and the different effects that policies and programs may have on them. Simple descriptive statistics were used to analyze the data. Energy efficiency and energy pr...
