Evergreen Awards recognizes Delthy Farm with the award Best Biodiversity Farming in Zambia of 2026. This recognition highlights a pioneering agricultural model that integrates advanced technology, environmental stewardship, and economic sustainability. Delthy Farm has established itself as a leading example of how modern farming can address food security, climate resilience, and profitability simultaneously. 

Vertical Farming as the key technology

Delthy Farm’s success stems from a comprehensive farming initiative tailored to Zambia’s unique conditions. At its core is an advanced vertical aeroponic farming system currently focused on high-quality lettuce production. Unlike traditional soil-based methods, aeroponic towers deliver nutrients and water directly through the plant’s root zone inside the pole. 

This precision technique achieves up to 95% water savings compared to conventional farming while feeding plants with an optimum mix of nutrition. The result? Faster growth cycles and produce packed with higher levels of vitamins and minerals, delivering superior flavor and nutritional value to consumers.

The farm is already expanding this system to include animal fodder, mushrooms, and a variety of vegetables such as bell peppers, zucchinis, and cucumbers. Vertical farming allows Delthy Farm to produce fresh, local food year-round, even in challenging environments, while minimizing land use and external inputs.

Introducing BTO – Better than Organic produce

All operations adhere to the rigorous BTO (Better than Organic) standard, the strictest certification in the industry. BTO goes far beyond traditional organic rules by enforcing zero pesticides, herbicides, or fungicides (even natural ones), using only natural fertilizers, and prohibiting growth hormones. 

For livestock and integrated systems, animals receive 100% farm-grown BTO fodder perfectly balanced for proteins, healthy fats, carbohydrates, and minerals, along with significantly more space than conventional or standard organic requirements. This ensures exceptional animal welfare and produces healthier meat, milk, and eggs.

How Biodiversity is boosting results

Biodiversity forms another pillar of Delthy Farm’s model. Through careful crop combination and rotation, the farm creates thriving ecosystems that naturally support pollinators, beneficial insects, and soil health, enhancing resilience against pests and climate variability without any chemical interventions.

Less waste, more food, more profit

A key innovation is the farm’s focus on loss reduction. Pre-harvest losses are minimized by producing only what has been sold upfront through strong market linkages and demand-driven planning. Post-harvest losses are further reduced through on-site processing techniques such as dehydration and smoking. 

These methods transform surplus produce into high-value specialty foods suitable for both local markets and export, turning potential waste into profitable, shelf-stable products that extend economic benefits across the value chain.

From Zambia to the world

The Delthy Farm Concept, entirely developed in Zambia by Zambian experts, positions the country as a continental leader in sustainable agriculture. By blending aeroponic technology, BTO standards, biodiversity practices, and circular economy principles, Delthy Farm demonstrates that African nations can leapfrog traditional models and achieve food security, job creation, water conservation, and export potential simultaneously. 

Zambia is now a shining role model for other African countries seeking to build climate-resilient, profitable, and inclusive food systems. This homegrown innovation not only boosts local economies and nutrition but also inspires regional collaboration and investment in green agriculture.

How Delthy Farms is sharing their success

Importantly, the Delthy Farm concept is designed to be scalable and inclusive. Other farms across Zambia and the broader African continent are warmly invited to join through flexible partnerships and franchise models. By sharing knowledge, technology, and the proven BTO framework, Delthy Farm aims to create a network of like-minded producers, accelerating the adoption of regenerative, high-efficiency farming and amplifying impact across the region.

Congratulations to the entire Delthy Farm team on this well-deserved recognition. Their work embodies the spirit of the Evergreen Awards: innovation that nurtures people, planet, and prosperity for generations to come.
