The objective of INAPRO is to mobilise industry, member states and stakeholders to promote a new and innovative technical and technological approach right up to an Aquaponic system which allows a nearly emission free sustainable production and contributes remarkably to global food security for the 21st century. Considering that traditional Aquaponic systems, combining aquaculture and hydroponics, have a great potential in saving water and energy and recovering nutrients from wastewater by value chains, the project aims at a real breakthrough for these systems towards commercialization. This will be achieved by a) the model based optimisation of the system concept in respect to water consumption and quality, environmental impact, waste avoidance, CO2 release and nutrient recycling, energy efficiency, management efforts and finally costs and b) the integration of new technologies containing cutting edge approaches such as: 1) innovative one-way water supply for horticulture and water retrieval by condensation, 2) alternative water and energy sources, 3) optimized filter systems, 4) intelligent sensor and management network for an optimized system construction and operation. The viability of INAPRO systems will be proved in concept-based demonstration projects both in rural and in urban areas that offer a potential economic advantage while simultaneously reducing water and carbon footprint. The dissemination activities (to policy, public and end-users) will open new market opportunities and improve market access inside and outside Europe for producers and technology suppliers. These ambitions meet perfectly with the EU strategies under Europe 2020 to face the challenges of dramatic water resource developments in Europe and worldwide. The project supports particularly the Innovation Union with the EIP Water as one key initiative and further the Common Agricultural Policy and will consequently be closely connected to an EIP Action Group in agricultural water management.
