Which of the following practices can enhance food sustainability?

Practicing crop rotation and diversification is a key method that promotes food sustainability. This approach involves alternating the types of crops planted in a specific area across seasons, which helps in maintaining soil health, reducing pests and diseases, and improving crop yields over time. Crop rotation prevents the depletion of specific nutrients in the soil that can occur when the same crop is planted repeatedly. Diversity in crops can also enhance resilience against adverse weather conditions and pests, ultimately supporting a more sustainable agricultural system.

In contrast, other mentioned practices do not contribute positively to food sustainability. For instance, an over-reliance on chemical fertilizers can lead to soil degradation, water pollution, and loss of biodiversity. Neglecting soil health generally undermines the essential foundation for productive agriculture, leading to lower yields and increased vulnerability to environmental changes. Importing food products for convenience can inflate carbon footprints due to transportation and can undermine local food systems, making communities less self-sufficient and less sustainable overall.
