In the heart of Nigeria, a groundbreaking project is redefining sustainable agriculture and food security. Rofiat Bunmi Mudashiru, a researcher from the Department of Civil Engineering at Federal Polytechnic Offa, has spearheaded the design and construction of an innovative aquaponics system. This system, detailed in a study published in ‘ABUAD Journal of Engineering Research and Development’ (Afe Babalola University, Ado-Ekiti, Nigeria), is not just a local solution but a model that could revolutionize farming practices globally, particularly in regions with limited arable land.
The aquaponics system, a harmonious blend of hydroponics and aquaculture, is a closed-loop system where fish waste provides nutrients for plants, and the plants help purify the water for the fish. Mudashiru’s project, situated in Offa, Nigeria, has already demonstrated remarkable results, showcasing a shorter growth cycle for crops like cucumbers and peppers. “The integration of organic waste materials as growing mediums not only reduces costs but also enriches the nutrient profile, leading to optimized plant production,” Mudashiru explained.
The construction phase was meticulous, involving civil engineering, plumbing, welding, and planting works. A farm base of 8m x 4m was built for hydroponics, complemented by a concrete tank base of 3m x 2m x 0.6m to hold a 2000-liter fish tank. The hydroponics section was equipped with polystyrene floats carrying lightweight disposable cups filled with rice husk and palm kernel shells, serving as the planting medium. This design ensures efficient water use and minimizes the need for chemical-based nutrients, a significant advantage in regions where water and land are scarce.
The implications of this research extend beyond local food security. As the world grapples with climate change and resource depletion, sustainable agricultural practices like aquaponics become increasingly vital. Mudashiru’s work highlights the potential for commercial applications, particularly in urban farming and vertical farming. “This system can be scaled up for commercial use, providing fresh produce and fish in urban areas where land is limited,” Mudashiru noted.
The environmental benefits are equally compelling. By reducing the need for chemical fertilizers and pesticides, aquaponics systems contribute to cleaner waterways and healthier ecosystems. This aligns with global efforts to promote sustainable development and combat environmental degradation.
Looking ahead, the study published in ‘ABUAD Journal of Engineering Research and Development’ serves as a blueprint for future developments. It offers a practical guide for designing and building effective aquaponics systems, emphasizing the use of locally available materials and sustainable practices. The success in Offa could inspire similar projects in other regions, fostering a global movement towards sustainable agriculture. As Mudashiru’s work demonstrates, the future of farming lies in innovative, eco-friendly solutions that enhance food security while preserving our planet’s precious resources.
