Environmental Benefits
- Macadamia trees are perennial, providing year-round cover that prevents soil erosion, improves soil fertility, and contributes to carbon sequestration.
- They also offer shade, contributing to agroforestry systems and supporting biodiversity.
Macadamia farming has significantly impacted Kenyan farmers, both positively and negatively, depending on various factors such as market access, farming practices, and environmental considerations.
Job Creation
The entire value chain, from farming to processing, has created jobs in rural areas, particularly for women and youth involved in harvesting and processing nuts
Macadamia farming has significantly impacted Kenyan farmers, both positively and negatively, depending on various factors such as market access, farming practices, and environmental considerations.
1. Economic Diversification
- Farmers diversify their income sources, reducing dependence on traditional crops that are often vulnerable to price fluctuations and climate change.

Macadamia storage tips
Maintain quality during storage by:
• Using well-ventilated, cool, and dry storage areas
• Protecting nuts from rodents and pests
• Storing in jute or sisal bags for long-term storage
• Using net bags for temporary farm-level storage
Drying of macadamia
Proper drying is essential for long-term storage and quality:
• Air-dry nuts in shade to prevent shell cracking
• Use meshed trays or mats for even drying
• Maintain drying temperatures between 55-65°C when using heated air
Post-Harvest Processing of Macadamia
1) Dehusking
Timing is critical:
•Process nuts within 2 days of collection
•If immediate dehusking isn’t possible, spread nuts in thin layers (6-7 cm) on trays under shelter
•Avoid storing unhusked nuts in sacks to prevent mold growth
Choosing Your Variety
Consider these factors:
· Farm altitude and rainfall.
· Local climate.
· Market demand (quality vs. quantity).
· Harvesting preferences (seasonal vs. year-round).
· Processing capabilities and resources.
