- Homegreens: Aquaponics and EducationPublication . Carreira, Rute; Pessanha, LuisThe Homegreens project aims to develop small freshwater or saltwater aquaponic systems, which can be in-stalled in schools, serving as a pedagogical tool for the apprenticeship of subjects such as biology and sustaina-bility to the juvenile audience. A multidisciplinary team of designers, biologists, and agronomists was responsi-ble for the project’s research. The development and installation of experimental models, for qualitative analy-sis of user interaction, determined the methodology layout. This small-scale aquaponic system consists of two different grow beds, an aquarium with a capacity of 45L, a separating barrier for plants’ roots, a biofilter mesh with an integrated aerator, a valve for sediment cleaning, and two tripods. The involvement and the interaction with the Homegreens’ aquaponic system provides a group learning oppor-tunity, which contributes to environmental literacy in children with relevant values and experiences.

- Homegreens - Aquaponics System as an Educational Tool towards a Sustainable FuturePublication . Carreira, Rute; Diz, Francisco; Pessanha, Luis; Bernardino, Raul; Franco, Inês M.; Mota, Alexandra; Faustino, Emanuel; Silva, Orlando R.; Ferreira, Susana M. F.Aquaponics is an integrated production practice that emerges from the combi-nation of two farming techniques: hydroponics and aquaculture. It consists in a simulation of a natural ecosystem that grows plants without soil substrate in the nutrient enriched waters recirculated from aquaculture systems. This type of production offers several advantages, namely economic and ecological ones. Homegreens is a project that aims to create small saltwater and freshwater aquaponic sys-tems, which can be installed in schools and serve as a didactic tool for introducing contents such as biology and sustainability to a juvenile audience. Implemented by a designers, biol-ogists and agronomists’ multidisciplinary team, the methodology was based on the develop-ment and quantitative validation of prototypes, and the installation and qualitative analyses of user’s interaction. These small scale aquaponic systems consists on a grow bed, an aquarium with a capacity for 45L, a protection barrier for the plant’s roots, aeration, biofilters and a thermostat. Sever-al simplified models were developed, presented and installed in two primary schools. Labor-atory tests were conducted to validate the use of a cork grow bed and a 3D printed polya-cid lactic (PLA) aeration and biofilter system. Children’s engagement and interaction with these simplified models, indicates that these systems will provide a biology and sustainability related group learning opportunity.
- Designing for a Multispecies House-hold Development of Pet ́s HabitatsPublication . Venâncio, Clara; Pessanha, LuísThis article makes a brief presentation of the development process of two prototypes that foster the environmental enrichment of two species of companion animals: guinea pigs and cats. The prototypes Domus Petra and Locus Turi were the results of a research project carried out within the scope of a master's thesis in product design. The main goal of the project is to research how product design can promote animal welfare, health and, also, human wellbeing. There were identified cats and guinea pigs’ main characteristics and needs, as well as the problems of the spaces they inhabit when integrated into multispecies households. The animal’s artificial habitats were re-evaluated and redesigned to encourage the practice of normal species behaviours. The focus lays on the relationship dynamics between humans and companion animals: their practices of care; feeding; maintenance of animals and their products; ways of living together; and human-animal-objects interactions. The Domus Petra and Locus Turi prototypes seem to be usable by animals and humans, however, future improvements and developments should be considered. There is a need to explore other approaches to non-anthropocentric design practices, and other paths to include animal perspectives in product development.
