- Increased and diversified farm income.
- Reduced dependence upon coconut products with unstable market prices.
- Improved growth and yields of coconut palms and ease in finding the fallen nuts due to management of intercrop through weed control, use of fertilizers, etc.
- Intercropped plants such as bananas and pineapples provide income in the shortterm, as it takes young palms six or seven years to produce economic yields.
- Better use of good quality land located close to settlements.
- Canopy lowers air temperatures by 4–6°C lower and gives higher air relative humidity. These reduce evaporation from the soil and lower crop transpiration rates maintaining higher level of soil water availability for intercrops.
- Competition between intercrops and coconut, for water or plant nutrients.
- Intercrops may incur losses to farmer if planted where light is insufficient.
- Intercrops may harbour diseases or attract pests harmful to coconuts.
- Fertilisers needed for intercropping may not be affordable.
- Tillage for intercrops may damage shallow-rooted palms reducing copra yields.
- The growth habit of some intercrops may cause difficulty in harvesting coconuts.
- Intercropping demands a higher level of skill from the farmer.
- Wildfire sometimes appears to be a major disincentive to establishing forestry and agroforestry intercropping, with various reasons for lighting fires being identified. On the other hand, coconut, citrus and pineapple are considered as fire-retardant food and may provide an incentive for the community to protect planted areas by using firebreaks around the reforestation sites .
