Agricultural economics is the applied field where theoretical agricultural strategies are implemented to improve production and achieve economic development. Like other countries, Algeria has implemented important strategies to promote the agricultural sector as a key driver of the economy, along with the industrial and service sectors.

The study concludes that Algeria has managed, through the support mechanisms provided to investors in the agricultural sector, to promote this sector, albeit to a lesser extent compared to other sectors.
