This study investigated the effect of different vermicompost rates (10%, 20%, 30%) and pot volumes (4, 6, 8 L) on celery and red cabbage grown under green roof conditions in Cairo, Egypt, during 2014/2015 and 2015/2016. Increasing pot volume from 4 to 8 L increased vegetative growth and yield but decreased economic efficiency. A 20% vermicompost rate increased vegetative and yield characteristics, while 30% had a negative impact. Increasing vermicompost from 10% to 30% increased N, P, and K contents, but increasing pot volume from 4 to 8 L/plant decreased N, P, and K contents.

Benjamin Goldstein · · United States

This project aims to address uncertainties regarding the environmental performance of urban agriculture, using the Northeast United States as a case study. Existing literature lacks environmental appraisals comparing urban and rural food production, leaving questions about whether the benefits of reduced farm-to-fork distance are outweighed by energy demands of year-round growing systems, and if farm-scale resource efficiencies translate to meaningful shifts in a city's environmental footprint. This report comprises six chapters that explore and contribute to the understanding of urban food systems.

This 2-year study in Tamale (Ghana) and Ouagadougou (Burkina Faso) investigated the effects of biochar, wastewater irrigation, and fertilization on sandy, nutrient-depleted soils in urban vegetable production. Biochar addition (2 kg m⁻²) initially doubled soil organic carbon (SOC) stocks, but 35% SOC losses occurred afterward. Both biochar types had no effect on soil pH, phosphorus availability, or cation exchange capacity, though rice husk biochar retained nitrogen. The study found that the effects of biochar and waste water were less pronounced than reported elsewhere.
