This article discusses how agricultural development requires changes in productive systems under conditions of population growth, rising incomes, and urbanization. It distinguishes between cropping systems, production systems, and farm management systems, and examines how each should evolve in response to food demand. The author analyzes the balance between food crops and export crops, as well as between plant and animal production, emphasizing food security, resource efficiency, and the risks of dependence on external markets or animal-based consumption patterns. The article frames agricultural strategy as a structural response to development pressures rather than a purely technical adjustment.
