Aqua Horta aims to establish a sustainable aquaponic farm in Vallcarca, focusing on producing fresh, chemical-free, local produce while creating an engaging therapy garden for patients of the neighbouring hospital complex. This controlled ecosystem combines aquaculture and hydroponics to create a closed-loop system that minimizes water wastage and incorporates rainwater harvesting to enhance resilience against water shortages. Inspired by the neighborhood’s history of resistance, the farm embodies the values of diversity, resilience, and autonomy, demonstrating a commitment to decentralized systems through active community engagement and collaboration. Additionally, potential markets have been identified, including local organic shops, restaurants, and hospitals, which align with the farm’s ethos of sustainability and local production, ultimately promoting healthier food choices and supporting the local economy.
