Table A4.
Causes of rangeland degradation as ranked by the pastoralists in Ewa rangeland, Afar, Ethiopia.
| Causes | Study area(Overall) (n = 80) |
|
|---|---|---|
| Weighted value1 | Ranka | |
| Recurrent droughts (shortage of rain) | 0.32 | 1 |
| Heavy continuous grazing | 0.30 | 2 |
| Bush encroachment | 0.15 | 4 |
| Inappropriate management system | 0.23 | 3 |
1 = Most important; 4 = Least important.
Sum of weighted scores was developed to obtain the final ranking of the causes of range degradation and calculated as: weighted sum = sum of [(4 × number of responses for 1st rank + 3 × number of responses for 2nd rank. …. + 1 × number of responses for 4th)] divided by (4 × total responses for 1st rank + 3 × total responses for 2nd rank. … + 1 × total responses for 4th rank).
