Agroforestry is the agricultural practice of combining the management of annual crops and/or animals with trees. Agroforestry systems, largely composed of perennial crops, offer the resilience needed to address extreme climatic issues such as drought and torrential rain, along with social and economic factors that influence agricultural production of small-scale farmers.
