What is a key feature of agroforestry systems?

• A. Reliance on chemical pest control
• B. Integration of trees and crops
• C. Isolation of crop types
• D. Use of genetically modified organisms

Answer: (B)

The integration of trees and crops is a fundamental characteristic of agroforestry systems, distinguishing them from conventional agricultural practices. This approach not only enhances biodiversity but also leads to improved soil quality, microclimate regulation, and increased crop yields. By incorporating trees into agricultural landscapes, agroforestry systems can provide numerous benefits, such as habitat for wildlife, carbon sequestration, and enhanced resilience to climate change.

In this context, trees can provide shade or wind protection for crops, create a more sustainable and balanced ecosystem, and contribute to soil health through leaf litter and root systems that improve nutrient cycling. This integrated method contrasts with relying solely on monocultures or isolating different types of crops, which can lead to increased vulnerability to pests and diseases and reduced overall ecological health.
