The purpose of this study was to determine the effects of HIV/AIDS on farm income and
food production in Kavango region. Representative farm models of communal farms for
each of the two most common farming systems in Kavango region were developed.
These are the riverline and inland farming systems, which were then used to determine
the levels of farm income and food production at farm level under various HIV/AIDS
scenarios in terms of changes in resource availability and gender, based labour loss. The
scenarios used are (1) male adult illness (2) female adult illness (3) both male and
female adult illness. Non-linear programming models were used and run in GAMS to
determine levels of income and production for each scenario. Two representative models
were used, one each for Mashare and Mile 30 ADCs.
