The Regional and Local Economic Development Initiative, through its Aquaponics Programme, aims to explore and advance sustainable food production systems that align with a broader social development model. This component forms part of a strategic partnership between the University of KwaZulu-Natal and the KwaZulu-Natal Department of Economic Development, Tourism and Environmental Affairs. 

Objective and Strategic Purpose 

The Aquaponics Programme seeks to: 

• Conduct action research on aquaponics to inform the development and entrenchment of a social development model. 
• Support smallholder and emerging farmers to transition into cultivating higher-value agricultural commodities, which can play a significant role in reducing poverty and promoting rural development. 
• Establish sustainable aquaponics systems that can provide food, generate income, and build technical skills at the community level. 

Why Aquaponics? 

Aquaponics offers a sustainable and innovative alternative to conventional agriculture, particularly in rural settings: 

• Nutritional Value: Enables the production of protein-rich vegetables and fish—important in communities with limited dietary diversity. 
• Profitability: Supports the cultivation of high-value crops and commercially viable fish species like catfish. 
• Climate Resilience: Systems are more resilient to climate change than traditional agriculture. 
• Resource Efficiency: Recycles water and nutrients, making it suitable for water-scarce areas if appropriate systems (e.g., JoJo tanks) are installed. 

Achievements at the Ndwedwe Site (2022–2024) 

This site, managed by a rural farmer outside of the Champions Programme, transitioned from a pilot to a small-scale commercial aquaponics system by 2024. Key outcomes include: 

• Successful Food Production: Organic vegetables and fish are being produced and consumed locally. 
• Seedling Business: A spin-off seedling enterprise supplies both the tunnels and community gardens. 
• Infrastructure Improvements: Water scarcity was addressed through the installation of JoJo tanks. 
• Youth Skills Transfer: Local youth gained hands-on experience in aquaponics and nursery management. 
• Technical Innovation: Introduction of catfish (instead of tilapia) proved more resilient during power outages and offered nutritional and market advantages. 
• Cost-Effective Operations: Utilized local labour and donations (e.g., solar systems), reducing operational costs. 
• Training and Support: A highly effective service provider facilitated community training and technical operations. 

Despite promising results, challenges remain: 

• Sustainability is still uncertain due to climate and operational risks. 
• Scaling will require ongoing technical support and access to capital. 

Learnings from the Amandawe Site 

Operated by a cooperative initiated by a former Champion, this site reinforced the programme’s key findings: 

• Viability in Rural Areas: Aquaponics systems can be successfully implemented in remote communities. 
• Site Selection Matters: Weather and water access are critical—poor site selection can hinder success. 
• High Start-Up Costs: May limit participation to those with some capital or external support. 
• Solar Panel Protection: Locating solar panels inside tunnels reduces theft risk. 
• Institutional Gaps: Aquaponics lacks a clear home within government structures, affecting coordinated support and scale-up opportunities. 

Programme Impact and Potential 

The RLEDI Aquaponics Programme has demonstrated that: 

• Action research can inform real-world innovation in rural economic development. 
• Smallholder farmers, with the right support, can implement and operate low-cost, climate-resilient food systems. 
• Aquaponics has potential not only for local food security, but also for developing rural agro-enterprises capable of supplying formal markets. 

To fully realise this potential, the following must be addressed: 

• Continued technical assistance for scaling operations. 
• Access to reliable water and infrastructure. 
• Institutional integration of aquaponics into formal agricultural and rural development strategies.
