American Logistics Aid Network (ALAN) is a non-profit logistics aid firm that provides supply chain assistance to non-profit organizations in times of crisis. It acts somewhat as a non-profit 3PL, connecting nonprofits seeking humanitarian aid goods, materials handling equipment, warehousing, logistics transportation, and expertise to an outstanding network of partner companies and organizations who help to deliver on their requests. In June of 2020, our team began an internship to identify and implement key process improvements for ALAN’s internal and external processes. This thesis is a summary of our findings, our solutions proposal, and their applicability to other non-profit organizations.

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.
This formula was used to estimate the nutrient uptake performance of aquatic primary producers from sampling observations; ANPP accounted for 16.26 metric tons of system wide N uptake, while aquatic ER contributed 6.07 metric tons N of nighttime remineralization and 5.7 metric tons of N throughout the water column during the day. The estimated yearly net aquatic N flux is 4.49 metric tons uptake, compared to about 12 metric tons yearly N uptake by the vegetated marsh (Treese, 2019). However, not accounting for animal respiration results in an underestimation of system-wide N remineralization, and not accounting for soil processes results in an underestimation of N uptake.
Much of the community in Rocky Point, Mexico, faces chronic poverty and limited economic development. However, using an asset-based community development model, a local non-profit organization is working to empower the people to take the community's development into their own hands. 1MISSION, through its community-driven projects and programs, is helping bring sustainable and meaningful development to Rocky Point.
