I would recommend option D, both A and B.
Both alley cropping and intercropping are sustainable practices that can help maximize the use of farmland while minimizing negative environmental impacts.
- Alley cropping involves growing trees alongside crops, which can enhance biodiversity, improve soil health, and provide shade and wind protection.
- Intercropping allows for more efficient use of land by growing multiple crops together, which can improve soil health, reduce pest infestations, and increase overall yield.
Both practices support sustainable agriculture and can lead to more resilient farming systems. Sharecropping, on the other hand, primarily addresses landownership and economic arrangements rather than sustainable farming practices.
