Regardless of size or location, farms are closely connected to their surrounding environment—through the soil, water systems, insects and wildlife. All organisms within an ecosystem depend on each other, and the healthiest ecosystems contain a wide range of species that interact in diverse and mutually beneficial ways. Agro-biodiversity tries to mimic natural species diversity by increasing the variety of crops and other organisms in a single farming system. It offers farmers many useful tools to improve soil health and reduce reliance on inputs without sacrificing profits. Having more species working together creates more stable farming systems that are resilient against harsh conditions like severe weather, pests and disease.
