The Philippines is particularly prone to natural disasters due to its geographical location and physical environment. The country experiences an average of 20 typhoons yearly, which trigger landslides, flash floods, mudslides, widespread flooding, and cause destruction and damage to homes, community buildings, communications, infrastructure, and agriculture. To address these hazards and slow on setting climate change impacts, the integration of lemon trees in vegetable farms can be a suitable option for slope protection. Planting of trees such as Calliandra reduces weed growth, conserves soil moisture, and improves soil structure and fertility. Calliandra is planted in contour hedge-rows to decrease erosion on steep slopes, acts as windbreaks and as an understory component. The introduction of a tree crop that helps minimize soil erosion and provides additional income is a measure that increases the resilience of the community against the common natural hazards that occur in the location. The integration of citrus in vegetable farms aims at increasing the forest cover and enhance slope stabilization, and biological diversity. At the same time it aims to enhance the protective and productive values of watershed in an intensive vegetable-based production system in high elevation agro-ecological zones. The practice also aims to generate additional income.
