Summary : In Algeria, the majority of pastoral livestock production systems are located in the steppe, in particular in the Djelfa region (Algeria). Pastoral livestock production systems with a variety of characteristics have been developed in response to agro-ecological opportunities, demand for livestock commodities and remote social pratices (three pastoral livestock production systems are identified). The main livestock product of the region, red meat, is primarily directed towards the domestic market through the large market of Djelfa. The conclusions which emerge from this study can be formulated as follows: i) The coefficients (CV) for the series of climatic variables, in particular rainfall (CV\=17.59 to 82.70%), fluctuate more than those of market variables (CV \=8.92 to 24.74%) and the CV rainfall level shows the widest gap among the climatic factors: CV rainfall\=82.70%, CV (temperature and daytime temperature amplitude)\=17.59 to 49.60%)\; ii) In 2002, the averages of daytime temperatures and temperature amplitudes were respectively lower and higher than the seasonal norms, in particular at the end of winter. In spite of this situation, the offer on the market and price of the animals fluctuated less than the monthly or seasonal climate factors due to the various specific strategies of each pastoral livestock system and the seasonalities of the activities of sheep farming and croppping\; iii) Apart from those of the teg, the price and destocking of female animals were somewhat more sensitive to the differences than the others (CV females\=16.80 to 22.65%, CV males\=13.83 to 15.33%) though there were no significant correlations\; iv) In general, there are no significant positive or negative correlations between the series of market variables and climatic variables in the short term (r\= -0.89 to 0.55)\; v). It thus seems that the pastoral livestock production systems of the region can reasonably mitigate the disadvantages caused by the climatic fluctuations which are registered around short period trends owing to the various anti-risk measures implemented at the level of the pastoral livestock production system. |
