Role of income from rice cultivation on livelihoods of rice farmers: Evidence from Ahero Region, Kenya

February 2023

In Africa, the demand for rice has increased rapidly as urbanization progresses and assistance is being provided to improve productivity and rice farming management. In the rice-cultivation area near Lake Victoria in western Kenya, where farmers are called “outgrowers”, wage labor costs put pressure on rice farming and reduce profits. However, wage laborers were rice farmers living in the same area. The...
