An emergy analysis of environmental sustainability in urban agriculture: evidence from protected agriculture in Beijing, China

Urban Farm DB summary

This study applied a "farm-to-table" emergy method to analyze the environmental sustainability of two typical urban farms in Beijing, China: a suburban greenhouse farm and an aquaponics farm. The aquaponics farm demonstrated a lower environmental loading ratio and a higher emergy sustainability index compared to traditional greenhouse farming, but it required more emergy inputs.
