The
present version of the index is based on annual livestock figures
corresponding to the 15 State Veterinary Districts in
Calculation
of the index:
1.
The number of cattle, sheep and goats counted within each State Veterinary
District were used.
2. Goats and sheep were recalculated into large stock unit by dividing the
total number by 5.25. I.e. one normal cattle is equal to 5.25 goats.
3. A buffer with a radius of 10 km was created around each borehole, in
order to determine the areas occupied by livestock within each State
Veterinary District (SVD).
4. The density of livestock within each State Veterinary District was
calculated by dividing the total area within 10km from any borehole (within
each SVD) with the total number of LSU within each SVD.
5. Four classes were defined for the dependable growth period, i.e. 0 days,
>6 days, >33 days and >85 days (I.e. the same as used for the
population pressure index).
6. Threshold values are still theoretical.
The variables represented in this monitoring indicator are: (1) livestock per veterinary unit; livestock (cattle, sheep, goat, donkey, horses) counted by veterinary extension. These data are summarized and produced annually. (2) dependable growth period, (3) restriction of boreholes
