Sustainable Aquaponics Solutions for Arid Zones: A Case Study in Israel

Strategic Insights -

In the midst of land desertification, water scarcity, and food security challenges in arid zones, researchers have been working on innovative agricultural solutions to mitigate these issues. A recent study from the National Center for Mariculture in Israel has demonstrated the potential of aquaponics as a sustainable solution for food production in arid regions. The research, funded by various organizations including the European Research Council and the Netherlands Organization For Applied Scientific Research, has led to the development of an integrated dynamic model for an on-demand industrial aquaponics system in Israel.

Key Takeaways:

  • The study investigated innovative water and energy-saving strategies using an integrated dynamic model for an on-demand industrial aquaponics system in Israel, achieving phosphorus use efficiency of 96%, water use efficiency of 97%, and energy consumption of 0.56 kWh/day/m2.
  • The optimized system design resulted in an aquaponics system with approximately 420 m3 RAS, 6.85 ha HPS, and 40 m3/d DU, requiring 4500 m2 photovoltaic panels and 5000 m2 solar heating system for daily energy self-sufficiency.
  • The system utilized evaporative cooling, outdoor shading, and mechanical cooling to control temperature and humidity in the greenhouse, and dehumidification technologies to recover 22% freshwater from seawater and increase nitrogen use efficiency by 18%.
  • The aquaponics system was designed with scalability in mind, allowing it to be adapted and applied extensively across diverse peri-urban regions and arid zones globally.
  • The research concluded that the system model was initially devised for conditions in Israel but has been designed to be applicable in other regions, providing a promising solution for food production in arid zones.
  • The study also highlighted the importance of reducing water and energy consumption, as well as increasing crop yields and wastage reduction in aquaponics systems.

Statistics:

  • Approximately 420 m3 RAS (recirculating aquaculture system), 6.85 ha HPS (hydroponics system), and 40 m3/d DU (desalination unit) were required for the optimized aquaponics system.
  • The system achieved phosphorus use efficiency of 96%, water use efficiency of 97%, and energy consumption of 0.56 kWh/day/m2.
  • 4500 m2 photovoltaic panels and 5000 m2 solar heating system were required for daily energy self-sufficiency.
  • 22% freshwater was recovered from seawater using dehumidification technologies, and nitrogen use efficiency was increased by 18%.
  • The system utilized 1.5 L/day/m2 freshwater input and had a temperature and humidity control system.
