Most urban agriculture sites experience challenges related to sustainability, but in the Sonoran Desert, even more challenges arise as a result of a unique climate, soil conditions, intense storms, and water scarcity. The objective of this project was to obtain information on common barriers to urban agriculture in the Sonoran Desert, as well as ways to overcome these barriers that will be made public for the purpose of improving sustainability of similar agriculture projects. I used interviews with gardeners and farm staff as my primary research method to gain insight to these barriers and solutions, and I coded their responses relating to challenges according to frequency mentioned. Using my findings, I compiled a thorough list of recommendations that urban agriculture projects in the Sonoran Desert or in similar climatic areas can use to achieve greater success and sustainable outcomes.
role play simulation modeled around Michigan wolf management. In this case, role play simulation is a game fabricated to reflect the complexity of real-world conflict. The goal of the exercise is to engage players in mock negotiation and expand their knowledge of wicked environmental problems. By encouraging participants to question their own thought process, the activity aims to foster a transformational experience.
e-Governance and apply methods to measure and propel that perspective to an operationally adaptable framework applicable to regional government.
The rise in urban populations is encouraging cities to pursue sustainable water treatment services implementing constructed treatment wetlands (CTW). This is especially important in arid climates where water resources are scarce; however, research regarding aridland CTWs is limited. The Tres Rios CTW in Phoenix, Arizona, USA, presents the tradeoff between greater water loss and enhanced nitrogen (N) removal. Previous research has suggested that water loss due to transpiration is replaced by a phenomenon termed the Biological Tide. This trend has been documented since 2011 by combining transpiration values with a nitrogen budget. Calculations were made at both the marsh and whole-system scale. The purpose of this paper is to demonstrate how the Biological Tide enhances N uptake throughout the CTW. Results indicate that about half of the nitrogen taken up by the vegetated marsh is associated with new water entering the marsh via the Biological Tide with even higher values during warmer months. Furthermore, it is this phenomenon that enhances N uptake throughout the year, on average, by 25.9% for nitrite, 9.54% for nitrate, and 4.84% for ammonium at the whole-system scale and 95.5%, 147%, and 118% within the marsh. This paper demonstrates the Biological Tide’s significant impact on enhanced N removal in an aridland CTW.
