AQUAPONIA, a novelty in environmental education
AbstractAquaponics is an activity that combines aquaculture and hydroponics. Usually, it consists on a closed-circuit combination of sh farming and plant growth, both of which are destined for human consumption. Fish excrete ammonia, which, after transformation by nitrifying bacteria, is used as nutrients by plants. This way, water becomes clean again and available for sh. This closed circuit allows to increase food production in a sustainable way, to save water and to avoid soil and water pollution. Aquaponics is a transversal concept, ranging from the local subsistence agriculture context to a global level, marked by overpopulation and the depletion of resources. For this reason, aquaponics is being approached in an emerging way by environmental education programs all over the world. EPAMAC is a professional school in Portugal, which is present in several projects associated with the subject, and has been proven to be an ambassador of the concept of aquaponics in the Portuguese educational system.
