What aspect of agriculture does agroforestry aim to improve?

Agroforestry aims to improve biodiversity and sustainability through the integration of trees and shrubs with crops and/or livestock in agricultural practices. By incorporating perennial plants into farming systems, agroforestry enhances ecological diversity, which can lead to more resilient farming practices, improved soil health, and better water management.

This approach can create a more sustainable agricultural system by providing multiple outputs such as timber, fruits, and fodder while also helping to create habitats for wildlife and improving the overall ecosystem services. Increased biodiversity can also help with pest control and pollination, reducing the reliance on chemical inputs and promoting a healthier agricultural environment.

The other options, such as soil pH levels, livestock health, and fertilizer application rates, are important factors in agriculture but are not the primary focus of agroforestry practices. Agroforestry specifically emphasizes the synergy between trees, crops, and livestock to promote a holistic approach that enhances biodiversity and sustainability.
