SUMMARY
- The Ojos Negros valley, in Baja California, Mexico, has an arid climate and is, therefore, subject to frequent
droughts.
-
Agriculture and animal husbandry are the primary economic activities in the valley.
Animal husbandry is accomplished primarily by dryland farming, which is drought sensitive.
- The climatological analysis shows that droughts in the Ojos Negros region are likely to be moderate, to last 2 yr, and to
recur every 4 yr on the average.
- Appropriate herd management can help reduce the impact of drought. The members of the herd
should be evaluated to eliminate those that are less useful. Planning for herd size should consider the periodicity of drought.
- A program of soil-and-water conservation is needed to help cope with recurrent droughts.
