AQUAPONICS SITE VISIT at ARID EDEN

Overview

On June 20, 2024, the Aquaponics Project team conducted a field visit to Arid Eden in the Hardap region. The purpose of the visit was to assess potential sites for the construction of new aquaponic systems and to engage with Mr Jean the constructor responsible for building demonstration aquaponic systems. The team, consisting of Mr. Patrick Hilger, Dr. Clemens von Doderer, and Mr. Jean Bower, was on-site to survey and evaluate the potential location for constructing a demo aquaponic system.

Activity Objectives

The primary objective of the pre-visit trip to Arid Eden was to survey potential sites suitable for hosting the demonstration aquaponic systems. Once successful, it is hoped that the project can be scaled up within the framework of the “Rural Revive” project activities, especially with the Vocational Training & Horticulture setup in mind.

Upon arrival at the site, the team observed ample space and a high need for an aquaponics system at Arid Eden. It was then agreed by the Aquaponics Project team, along with Mr. Jean Bower, to proceed with a new layout design featuring Gravel Media Barrels, 4x 1000 L Tanks, DWC, a hothouse (covered Greenhouse part), and Zin roofing to insulate the fish part. Additionally, Mr. Stephan will provide shade netting to enhance the aquaponic system.

Background of Arid Eden Site:

The Arid Eden Project, based in the NamibRand Nature Reserve, aims to build a more sustainable, resilient, and inclusive tourism and conservation economy under the banner of the 5 Cs (Consciousness, Conservation, Community, and Commerce). This project will be the ideal host to set up the first desert-based aquaponic pilot system in Namibia. Aquaponics, with its water efficiency (using 95% less water than conventional agriculture), aligns with the vision of showcasing sustainable local food production. As a closed-loop ecosystem using no chemicals, it is inherently organic.

For instance, in an open-field production, 200 liters of water are used to produce 1 kg of tomatoes, whereas in a well-run aquaponic system, only 1.5-2 liters are required to produce the same amount. This system will serve as the ideal missing link in the “Heart & Home” concept, welcoming guests on arrival and contributing to the “local is lekker” and “reduced food mile” (i.e., reduced carbon footprint) principle message.

By implementing this system, Arid Eden will take a significant step toward sustainable development and environmental conservation, showcasing the benefits of aquaponics in a desert environment.

This report aims to provide a comprehensive overview of the field visit and the strategic steps taken towards the implementation of the aquaponic systems at Arid Eden. We look forward to the successful execution of this project and its positive impact on the community and environment.
