Organic cycleClimate changeModeling the Potential Productivity of Urban Agriculture and Its Impacts on Soil Quality Through Experimental Research on Scale-Appropriate Systems
2020John Taylor · Frontiers in Sustainable Food Systems · United States (Rhode Island)
This long-term replicated trial in Rhode Island evaluated the yield performance and soil quality impacts of four small-scale food production systems over three summer growing seasons. While total marketable food yields (2.22 to 2.96 kg m-2) were modest compared to biointensive agriculture (4.64 kg m-2), individual crop yields often exceeded regional and national averages without soil quality loss. The study addresses a lack of experimental research on urban agriculture and provides a framework for normative research, offering more reliable yield estimates for modeling urban production potential.

2020Jennifer Engels, Sheree J. Watson, Henrietta Dulai, Kimberly Burnett, Christopher A. Wada, ‘Ano‘ilani Aga, Nathan DeMaagd, J. J. McHugh, Barbara Sumida, Leah L. Bremer · PLoS ONE · United States (O‘ahu)
A researcher-farmer collaboration on O‘ahu's Sumida watercress farm conducted a 25-year trend analysis and a year of intensive spring water sampling. Negative correlations were found between historical crop yields and increases in the Oceanic Niño Index, temperature thresholds, and pest outbreaks. Despite urbanization, on-farm water quality was very high, and microbial analyses suggested the farm provides nutrient retention services to downstream systems. The study demonstrates that challenges facing urban agricultural systems shift over time.
Environmental trade-offsCommunityClimate changeBiodiversityOrganic cycleThe underutilized role of community gardens in improving cities’ adaptation to climate change: a review
2019Mysha Clarke, Melissa Davidson, Monika Egerer, Elsa C. Anderson, Nakisha Fouch · People Place and Policy Online · United States
This paper argues that community gardens should be a prioritized element of green infrastructure to improve cities' adaptation to climate change. Community gardens can reduce urban heat islands, provide ecosystem services, and increase stormwater retention. However, a qualitative analysis of 18 policy documents for Baltimore, Chicago, and New York City, U.S.A., found that green infrastructure for climate change adaptation prioritizes rain gardens, bioswales, and green roofs, but seldom acknowledges the role of community gardens.

2019Gaston E. Small, Paliza Shrestha, Geneviève S. Metson, Katherine Polsky, Ivan Jimenez, Adam D. Kay · Environmental Research Communications · United States
Survey data from 142 gardeners and urban farmers in the Twin Cities Metropolitan Area, USA, characterized phosphorus (P) and nitrogen (N) inputs and harvest, and measured soil P concentrations at a subset of sites. Median application rates were 300 kg P/ha and 1400 kg N/ha, with low nutrient use efficiencies (2.5% for P, 5.0% for N). Garden soils had a median Bray P value of 80 ppm, far exceeding recommended levels, indicating a buildup and potential loss of P and N. Urban gardens, though only 0.1% of land area, constitute one of the largest inputs of P to the watershed.

2019Sally Brown, Ned Beecher · Compost Science & Utilization · United States
This study modeled the carbon benefits and costs of biosolids compost use in King County, Washington. Soil carbon sequestration was highest for use on disturbed soils, such as new housing developments, neglected urban soils, or highway right-of-ways (–1.1 Mg CO2eq per Mg compost), and lowest for use in well-tended yards or other highly maintained landscapes (–0.036 Mg CO2eq per Mg compost). Compost use for tree growth, calculated over a 30-year period, added above-ground sequestration benefits ranging from –1.53 Mg CO2eq per Mg compost for a mature tree grown on a healthy soil to –4.58 Mg CO2eq per Mg compost for a newly planted tree grown on a disturbed site. Assuming a 20 km haul distance, transport costs ranged from 0.005 Mg CO2eq per Mg compost for delivery in a 5 Mg truck to 0.09 Mg CO2eq per Mg compost for pick up in a personal vehicle.
