Overview
ABSTRACT
In a context of global questioning for a more sustainable diet, the low production of quality animal protein in densely populated urban areas is a path investigated by various actors. However, aquaponics can produce under controlled conditions fish and edible plants characterized by low ecological footprint and toxic pollutant load in comparison with some fish exposed to ecosystem pollution. Under the prism of sustainable food, this feedback presents and discusses the scientific, economic, societal and pedagogical elements for the creation of an urban aquaponic farm in Occitania: the "Aquacosy" project.

INTRODUCTION
On a global scale, more than half the population lives in (peri-)urban areas, and this trend is growing. However, the majority of agricultural production takes place far from cities. To compensate for this geographical and social disconnect between producers and consumers, numerous (peri-)urban farming projects of various types are being developed to promote sustainable diets. .
Aquaponics is a low-cost agricultural production system based on aquaculture-hydroponics coupling and water recirculation. which meets a number of criteria for the sustainable production of local animal proteins with low levels of (eco)toxic chemical residues. Aquaponics is based on an optimized symbiosis between aquaculture (aquatic species producing nutrient-rich organic waste for the plants) and hydroponic above-ground market gardening (which acts as a purification station: the plants use the organic matter...
