Tanzania is one of Africa’s leading producers of cashew nuts, with the harvesting of cashew nuts in Tanzania playing a vital role in the country’s agricultural economy. The Tanzania cashew nut industry contributes significantly to foreign exchange earnings and supports millions of smallholder farmers.
This article explores the cashew nut harvest process, growing conditions, challenges, and the economic impact of this thriving industry.
Cashew Nuts in Tanzania
Cashews are unique nuts that cannot be consumed raw immediately after harvest due to their toxic outer shell. They must be heat-treated before being safe to eat. Cashews are known for their delicate flavor and slightly firm texture.
Unlike many nuts, cashews are suitable for individuals with food intolerances due to their low levels of natural food chemicals. However, a small percentage of people may experience allergic reactions.
Processed cashew nuts are transformed into various products, including raw, roasted, salted, unsalted, sweetened snacks, nut spreads, milk, and drinks. When buying raw cashews at markets or retail outlets, customers often seek plump, meaty nuts.
Tanzania’s Cashew Nuts Industry
Cashew nut farming in Tanzania is a vital part of the country’s agriculture and economy. The Tanzania cashew nut industry has seen significant growth, with production reaching 305,014 metric tonnes in the 2023/24 season, up from 189,114 metric tonnes in the previous season.
Growing Conditions for Cashew Nuts
Cashew trees thrive in Tanzania’s tropical climate. They require warm temperatures (20-35°C), well-drained sandy or loamy soil, and at least six hours of sunlight daily. Regions like Mtwara, Lindi, and Ruvuma provide ideal conditions, contributing over 87% of Tanzania’s cashew output.
The Tanzanian government has invested in subsidized agricultural inputs, such as seeds and fertilizers, to boost yields. Farmers are also encouraged to adopt modern farming techniques, including pest management and irrigation, to ensure sustainable cashew farming practices.
The Cashew Nut Harvest Process in Tanzania
Cashew nut harvesting in Tanzania is a meticulous process. It begins with the flowering of cashew trees, which typically occurs between November and January. The trees produce cashew apples, which ripen between February and April. Harvesting usually takes place from March to May when the apples turn yellow or red, indicating maturity.
Farmers use manual methods to hand-pick cashew apples. Skilled workers climb the trees or use long sticks to gently detach the apples. The nuts are then separated from the apples, dried, and processed. In recent years, some farmers have adopted mechanized tools to improve efficiency, but manual harvesting remains the most common method.
Harvesting methods include:
- Twisting the nut off the apple by hand
- Thrashing by stick and then collection
- Climbing the tree, thrashing, and then collection
- Shaking the branches
- Collection after natural drop
The first three methods often lead to immature nuts, which compromise quality and reduce yields. Immature nuts cause losses for farmers because they lack the desired weight and quality for sale. To test maturity, farmers use a simple water test: mature nuts sink, while immature ones float.
The best method is collecting nuts after they naturally fall, ensuring they are fully mature. The season starts with a small number of fallen nuts, peaks mid-season, and gradually slows down.
Post-Harvest Processing
Once harvested, cashew nuts are separated from their apples. They are then sun-dried for 2-3 days to reduce moisture to 9% or below. Proper drying is essential for storage and ensures the nuts maintain quality.
Drying takes place on specially prepared floors or mats made from bamboo or palm leaves. The drying area is rough and slightly sloped to allow rainwater runoff. The nuts are spread in layers no thicker than 10 cm, covering approximately 60 kg per square meter.
Regular raking ensures even drying. In the evenings, the nuts are heaped and covered, then assessed for further drying the next morning. Properly dried nuts produce a rattling sound when dropped.
Economic Impact of Cashew Farming in Tanzania
The cashew nut farming Tanzania sector is a cornerstone of the country’s economy. Cashew nut production significantly contributes to Tanzania’s economy. As of March 2024, cashew nut exports generated $227.1 million, up from $162.4 million in the prior season.
In the 2024/2025 season, Tanzania is projected to produce 595,000 tonnes of cashew nuts, a 95% increase from the previous season. This growth is driven by government support, improved market access, and higher global demand.
Cashew exports generate significant revenue, with the 2023/2024 season bringing in $227 million. The Tanzania Mercantile Exchange (TMX) has streamlined the auction process, ensuring farmers receive fair prices. This has boosted farmer incomes and encouraged more people to engage in cashew cultivation.
The increase in production and earnings is attributed to government efforts, including the provision of subsidized agricultural inputs and training for farmers.
Challenges in Cashew Nut Farming
Despite its success, the Tanzania cashew nut industry faces several challenges. Pests and diseases, such as fruit flies and powdery mildew, can reduce yields by up to 30%. Climate change also poses a threat, with unpredictable rainfall patterns affecting crop growth.
Farmers often struggle with limited access to modern tools and processing facilities. While the government is building new processing plants, more investment is needed to fully capitalize on the sector’s potential.
Sustainable Cashew Farming Practices
To address these challenges, Tanzania is promoting sustainable cashew farming practices. Organic farming methods, such as using natural fertilizers and pest control, are gaining popularity. Agroforestry, which integrates cashew trees with other crops, helps improve soil health and biodiversity.
The government is also encouraging value addition by supporting local processing facilities. This not only increases export revenues but also creates jobs for Tanzanians. By 2025, Tanzania aims to process 60% of its cashew nuts domestically, up from the current 10-20%.
Conclusion
The harvesting of cashew nuts in Tanzania is a vital activity that supports millions of livelihoods and contributes significantly to the national economy. With favorable growing conditions, government support, and a focus on sustainability, the Tanzania cashew nut industry is poised for continued growth.
