there is approximately 0.02 reduction in vulnerability (see Figure 13). This reduction becomes slower in
higher positive changes in temperature, about 0.01.
Changes in maximum temperature demonstrates effects contrary to minimum. A degree higher change in
maximum temperature effects about 0.02 drop in log crop farming income. On higher changes in maximum
temperatures (0 degrees above), the drop in crop farming income is less by .01. These effects in turn
translates to approximately 0.002 increase in vulnerability, although the rate becomes slower by 0.002 in
higher changes.

Covariates
Demographic characteristics
Age of the household head is consistently associated with lower probability of being malnourished across
all climate shocks. In addition female-headed households are less likely to have malnourished children.
On the other hand, households with indigenous member are more likely to have malnourished children as
well as those who have experienced illness in their households. Higher educational attainment of the
household head appear to reduce probability of malnourished children.
Household assets and infrastructure
Ownership of assets and access to infrastructure have mitigating effects on vulnerability to food insecurity
in terms of malnutrition. Those with safe water are less likely to have malnourished children compared to
those without safe water. Access to communication such as cellphone and telephone also reduces the
likelihood of having malnourished children. This is also similar with those who have access to media and
information such as radio. On the other hand, access to government programs is likely associated with
malnutrition as well as higher prices of food.
Policy Variables
Agricultural assets shows a robust effect on agricultural income and in turn on food insecurity. For instance
those with agricultural organization, thresher, dryer or irrigation pump will likely have more income on
