Both A and B (Alley cropping and Intercropping) are sustainable practices that can help maximize the use of farmland while minimizing negative environmental impacts.
- Alley cropping allows for increased biodiversity, improves soil health, and can provide additional resources (like timber or fruit) alongside traditional crops.
- Intercropping can enhance soil fertility, reduce pest populations, and improve overall yield by optimizing resource use and creating a more resilient farming system.
Sharecropping does not directly impact the sustainability of farming practices in the same way that alley cropping or intercropping does. Therefore, the best recommendation would be Both A and B.
