2022Hayden Hinton · Digital Archive @ GSU · United States (Atlanta)
A study in the Proctor Creek watershed in Atlanta, Georgia, measured field saturated hydraulic conductivity (Kfs) in soils under compaction, urban agricultural use, and lawn maintenance. Urban farming significantly increased soil Kfs (mean 2.2E-4 cm/s) compared to compaction (9.1E-7 cm/s) and lawn maintenance (9.0E-6 cm/s), limiting overland flow. Grain-size distributions showed no significant difference, indicating Kfs was controlled by land-management practices, not soil texture.

2022Margaret Marcy Emerson · Digital Commons - LIU Promoting Scholarship and Creative Work of LIU Students, Faculty, and Staff (Long Island University) · United States
In 2019, an estimated 35% of all food was lost or wasted in the U.S., and organic waste in landfills generates methane, a potent greenhouse gas. Composting significantly cuts the amount of food going into landfills, reducing climate and environmental impacts. Compost enhances soil, reduces the need for chemical fertilizers, improves soil water retention, provides carbon sequestration, and local composting conserves energy and reduces transport emissions.

2021John Taylor, Mamatha Hanumappa, Lara Miller, Brendan Shane, Matthew L. Richardson · Sustainability · United States (Washington, DC)
A public-access geographic information system (GIS) and Tableau dashboards were developed for comprehensive multifunctional urban green infrastructure (UGI) planning in Washington, DC. The dashboards enable stakeholders to identify existing UGI (150 ha) and potential areas for new UGI, including urban agriculture (UA). A total of 2734 ha is potentially suitable for UGI development, with 2575 ha potentially suitable for UA. Of this UA potential, 56% is located in Wards 5, 7, and 8, which are largely food deserts with primarily Black residents experiencing the greatest inequities. The tool allows users to prioritize equitable UGI development using population vulnerability indices.
