ABSTRACT
Covid-19 and the Ukrainian crisis have put the question of the "food emergency" back on everyone's agenda. If the need to ensure food security is unanimous in Algeria, this is however not the case for the future orientation of public policies in this area. This work attempts to contribute to this debate through a strategic prospective analysis to 2035 identifying new orientations for policies to support agricultural and fisheries production systems. It demonstrates that it is necessary, in order to better prepare for these "long and short time" challenges, to act now and to go further "than instead of" marginal adjustments. Also, these new policies must accompany "a double paradigm shift" that of the food model and the agricultural and fisheries production systems. The establishment of a cross-cutting food security policy in Algeria therefore appears to be essential to promote and succeed in this new dynamic.
