Table 2.
Total annual income by sources and income group surveyed in Burkina Faso and Ghana
| Income groups, Ghana | P value (t test) | Income groups, Burkina Faso | P value (t test) | |||
|---|---|---|---|---|---|---|
| Poor (n = 227) | Better-off (n = 239) | Poor (n = 262) | Better-off (n = 268) | |||
| Total net income ($(PPP adjusted) per aeu) ± standard error of the mean | 462 ± 15 | 3014 ± 270 | 0.0000 | 211 ± 6 | 1054 ± 59 | 0.0000 |
| Crop share | 0.33 | 0.53 | 0.0000 | 0.22 | 0.29 | 0.0001 |
| Livestock share | 0.10 | 0.07 | 0.0184 | 0.23 | 0.29 | 0.0033 |
| Non-forest environmental share | 0.23 | 0.13 | 0.0001 | 0.28 | 0.13 | 0.0000 |
| Forest share | 0.13 | 0.10 | 0.1067 | 0.08 | 0.10 | 0.9136 |
| Non-farm income share | 0.21 | 0.17 | 0.1431 | 0.19 | 0.19 | 0.2703 |
Households with negative net yearly income (n = 12 for Ghana and n = 6 for Burkina Faso) were not included in this analysis. Negative household income was due to, e.g., crop failure, loss of livestock, etc
To reduce the influence of extreme individual household values, income shares are here calculated as the means of individual household’s shares for each group of income sources (instead of the share of aggregated income by sources in aggregated total income across all households within each income group)
