Planning more scientifically ahead for drought and disaster drought is becoming inevitable due to the possible cut-back on State drought financial aid and generally stressed finances. The extensive stock farmer, especially in the arid zone, is therefore forced to become more independent from direct aid and to cope as far as possible with drought through advance planning and management strategies.
The object of this paper is to demonstrate, by making use of long-term rainfall data, that it is possible, to a significant degree, to quantify droughts and the probability of their occurrence. By making use of such information, management strategies can be timeously adapted and implemented to bridge droughts more successfully than has been the case in the past.
A long-term strategy. for example, that appears to have positive advantages and that can be implemented, is the fluctuation and reduction of stock numbers in relation to the rainfall - and consequently grazing capacity.
The financial implications of the reduction of stock numbers is investigated in this presentation.
