Revision with unchanged content. Droughts are an integral part of
semi-arid environments with far reaching negative consequences.
Management decisions in these environments should be evaluated against
scenario of uncertainty in climate and prices. There is a need for
forecasting environmental and economic risks associated with different
management options. Development of simple yet effective models to assist
in development of effective management strategies is vital. These models
should evaluate the potential risks and benefits of alternative
manage-ment strategies. This study evaluates the effects of stocking
rate for fixed and flexible strategies on range condition, ranch income
and expenses for a cow-calf enterprises. The analysis should assist
livestock manager produced sustainably in semi-arid environments. Use of
principles in the study can alleviate some of the drought induced
livestock mortalities through forward looking forage planning. The book
is addressed to livestock producers, ecologists, drought manage-ment
strategists and climatologists. It is a good guide for researchers in
the field of ecological modeling, particularly those looking at
developing more robust and user friendly models.
