The overall mean gross income from harvesting ‘ukindu’ ranges from 750 Tsh to 300,000 Tsh, with a
mean of 50,507 Tsh over the AEZ (Table 2.23). However, the overall net income is negative due to
higher production costs, especially in Delta north. However, it is important that the results be
interpreted carefully because farmers’ cost estimates may have been high. There was no significant
difference among the AEZ with respect to the variables reported in tables 27 and 28.
The amount of non-timber forest products lost per season is less than a quarter (Table 29). This is
indicated by 84.4% of the respondents who use non-timber forest products. It is only in the inner Delta
North, Inner Delta south and Delta north where a few respondents indicated that they lose between a
quarter and a half (Table 29).
