To tackle gender discrepancies an engendered strategy is required on land, not only housing.  For example, Gulyani and Connors (2002) illustrate the Kalingalinga slum upgrading project in Zambia resulted in negative effects for women. Following investment in slum upgrading the proportion of female-headed households declined with a rise in the proportion of renters and relocations. Slum upgrading raised living costs to women, and without legal land rights female-headed households were forced to relocate and resettle.
