Revitalizing Food Deserts Through Hydrophilic Architecture: A Case Study of Proposing Community Gardens in University of Arizona Dormitories
摘要
Hydrophilic design interventions offer a promising solution to solving issues associated with water scarcity in arid regions, particularly when it comes to combating food deserts. Tucson, situated in the Sonoran Desert, faces these challenges, with significant portions of its population residing in food deserts due to limited access to fresh produce. This paper explores the application of hydrophilic units on building facades, focusing on Maricopa Hall at the University of Arizona in Tucson as a case study.. These units, using desiccant materials like Calcium Chloride, extract water from ambient humidity and are particularly effective in Tucson's low-humidity environment. Through previous experimental testing, the units demonstrated a capacity to produce 1.8ml of water per day per unit. This paper aims to propose the use of these hydrophilic units as a case study and explores their application in redirecting the produced water for irrigating a variety of edible plants suitable for Tucson's climate, thus combating food deserts. Through multiple qualitative, quantitative and numerical explorations it was found that if the units were arranged on Maricopa Hall’s southern facade, they would be able to produce approximately 47 L/day. This yield would be able to support a large range of leafy greens, legumes, herbs, fruits and vegetables, thereby enhancing food security among students living in Maricopa Hall. Results highlight that integrating hydrophilic units into building facades not only contributes to water sustainability efforts but also promotes local food production, aligning with the United Nations’ Sustainable Development Goals (SDG). The paper addresses SDG 2 by enhancing food security through community gardens, SDG 6 by promoting sustainable water practices with hydrophilic architecture, SDG 11 by integrating sustainable design in urban dormitories, and SDG 12 by advocating for responsible consumption and production in food cultivation, and SDG13 by leveraging the adaptive capacity of buildings to optimize the use of prevailing weather conditions. This research underscores the transformative potential of hydrophilic design in addressing critical environmental and social challenges in arid, water-scarce regions, offering a pathway to sustainable urban interventions.
