Title: Call for National Tender for the Supply and Installation of Solar Dryer

Location: Adamawa
Employment Type: Supply / Service Contract

Background

• As part of the SUSTAIN project, NURU Nigeria is implementing an Aquaculture activity. This initiative is designed to train farmers on best practices in fish farming and to support the establishment of community water points, fingerlings, aquariums, and feeds, essential for this activity.
• Post-harvest losses of fish due to inadequate preservation methods remain a major challenge among smallholder fish farmers and fish processors. Traditional open-air sun drying and fuelwood smoking often result in quality deterioration, contamination, high fuel costs, environmental degradation, and health risks. Solar drying technology provides a sustainable, cost-effective, and hygienic alternative that improves product quality, extends shelf life, reduces post-harvest losses, and enhances income for fish processors.
• Traditional fish processing methods such as open sun drying and fuelwood smoking are commonly practiced but are associated with challenges including contamination, inconsistent product quality, excessive use of fuelwood, environmental degradation, health risks (especially for women), and reduced shelf life of fish products.
• The use of solar dryer technology for drying and smoking of fish offers a climate-smart, cost-effective, and hygienic solution. This intervention aligns with agricultural transformation and climate resilience goals, and supports livelihood improvement, food security, environmental protection, and women and youth economic empowerment.
