Management decisions during drought disasters

DROUGHT is a common occurrence in most parts of the traditional Angora goat region. Drought disasters also occur from time to time, and the decisions taken during these conditions usually determine the financial survival of the Angora goat farmer. The advanced computer technology of today, however, enables us to pre-determine the financial implications of various decisions and

choose the best options. For this purpose the animal production division at Grootfontein has developed a computer programme, which evaluates various management options under drought disaster conditions. The economic and other effects of the drought on farming is estimated for the drought period, as well as for the succeeding nine years, with the supposition that the following years are normal. Aspects that are taken into account in the evaluation include, among others, the following.

In order to use the programme, certain information from the farmer must be fed into the computer, such as stock numbers and production norms. After this information has been given, an endless number of possible management options that can be considered for use during the drought can be calculated. Every time that an option is produced, the programme will quantify the economic implications. Some of the questions to which answers can be found, include the following.

For each of the above, and many other questions, the short term as well as the long term implications can be calculated, and so enable the farmer to make better decisions.

To make the programme clearer, an example where the following two options are considered, can be examined.

Option 1: A disaster drought prevails and Farmer A decides to cull one-third of his stock in order to qualify for the drought disaster relief scheme. Because the cost of feed is so high, it is decided that animals will only be fed maintenance ration and therefore no increase by breeding will take place.

Option 2: A disaster drought prevails, but Farmer B decides not to cull any animals and also not to feed. Animals are thus allowed to die, and when enough animals have died to qualify for drought relief, feed is still not brought. If the drought continues for one year, the farmer expects that only a third of the animals will survive.


The gross margin (R/SSU/Year) and the cumulative gross margin (R/SS) of above-mentioned two options for 10 years are shown in Table 1. Year 1 is the drought year, while it is supposed that the following nine years are normal years.


In Table 1 it can be seen that Option 2 originally has a higher gross margin than Option 1, but that Option 1 recovered again very rapidly in the following year. The original high gross margin of Option 2 can be ascribed to the fact that more than a third of the animals died, and then a subsidy was received, but no feed was bought. When the cumulative cash flow position is considered, it can be seen that Option 2 would be the most economical long-term management practice to follow.

It must, however, once again be stressed that there are many options that can be considered, and that the above two are only used as examples. Individual cases can differ totally from the above, and for this reason it is best to treat them individually. If farmers wish to have more clarity about certain economic aspects of drought management, use can be made of the service offered by Grootfontein. It would be preferable for the farmer to personally discuss and study his own individual case with the personnel of Grootfontein in order to get the best help and advice.
