Effects of crop farming income on food insecurity as measured by per capita food expenditure are consistent
across the models. Increase in crop farming and income will lead to increased per capita food expenditure
hence will reduce vulnerability of population to food insecurity.
Covariates
Demographic characteristics
Across all climate shocks, age of the head of the family is negatively correlated with income from crop
farming and gardening. Female headed family is also negatively associated with income. Educational
attainment of the head of the family generally has negative effect on income which indicates that lower
educational attainment is associated with higher reduction in income. Age, sex and educational attainment
of the head of the family with regard to food expenditure is positive and significant. A year added on age
of the head of the family increases food expenditure by .006. In addition, as level of educational attainment
increases, food expenditure also increases..
Assets
Proxy variables of non-agricutural assets such as strong materials of walls and roof and access to safe water
have different effect on income. Dwelling unit with strong walls and roof has positive effect on income,
however families with access to safe water supply have negative effect. With regard to food expenditure,
both have significant positive effect. In particular, there is about 5 percent increase in food expenditure
among those families with strong materials of walls and roof as compared to those made from
light/makeshift materials. Similarly, expenditure on food is higher by 6 percent among families with access
to safe water.
Family’s access to information as approximated by ownership of radio and TV significantly influences
income from crop farming and gardening as well as food expenditure. Income of families with radio is 1315 percent higher than the income of families without radio. Families who own a TV have higher income
of about 6-9 percent as compared to those families who do not own a TV. Both the ownership of radio and
TV increase food expenditure by 2 percent and 9 percent, respectively.
Ownership of car and motorcycle as proxies to family’s access to transportation is significantly associated
with both income and food expenditure. Ownership of car tends to increase income by almost 51-54 percent
and thus increases spending on food by 15-17 percent. Onwership of motorcycle also gives higher income
by 16-20 percent therefore food spending increases by 6-7 percent.
Infrastructure
Included in the models are several variables that are proxies of communication infrastructure (ownership
of telephone), financial infrastructure (cash loan payments) and social welfare infrastructure (expenditure
on insurance and premiums). These variables, however, tend to have different effect on income. For
instance, both ownership of telephone and payments to loan affect income positively while expenditure
on social welfare affects income negatively. With respect to spending on food, both ownership of telephone
and expenditure on social welfare are associated with higher spending on food while expenditure on loan
decreases spending on food but not significant.
