This research investigated the potential and limitations of plant factories (vertical farming) for urban food production. The STACKED method was developed to assess plant factory performance across multiple scales, from leaf to facility to city, analyzing resource requirements including energy, electricity, water, CO2, and land area use for fresh vegetable production. The study found that while plant factories feature extensive climate control, their necessity, effectiveness, and efficiency remain questionable, and their effects on the urban energy balance were also assessed.

This study evaluated the optimal combination of three different modular extensive green roof structures and two types of local substrates (compost and soil + biochar) for Lactuca sativa L. var. crispa (lettuce) growth under tropical climate conditions, measuring physicochemical and biological properties of substrates and plant growth variables over seven weeks under rainy and dry conditions. A monolithic multilayer structure, high Mg concentrations, elevated amounts of 600 μm aggregates, and lower substrate bulk density were linked with higher L. sativa yield, but the specific substrate used was not associated with this result. Some physicochemical and microbiological properties of substrates changed by the experiment's end, with these changes dependent on climatic conditions.

This paper proposed a framework for risk management and communication of Gentle Remediation Options (GRO) to support phytomanagement strategies at contaminated sites. An extensive literature review mapped risk mitigation mechanisms, and the Swedish national soil guideline value model derived human health exposure pathways and ecological risks. Results indicated that most expected risk mitigation mechanisms are supported by literature, but knowledge gaps still exist. The framework was demonstrated to support the identification of GRO options for a case study site under two envisioned land uses: biofuel park and allotment garden.

This chapter discusses innovations such as improvements in energy efficiency in housing, the trend of recognizing waste streams as resource streams, and innovations in urban agriculture and urban forestry that reduce cities' ecological footprints. A factor constraining government action on resource conservation and waste reduction is concern over employment costs. In most cities in the Global South, the potential for new employment in resource conservation is rather less due to lower resource use and higher levels of recycling, reclamation, and reuse.

This research studied how equity can exist at the intersection of regenerative and biophilic design strategies within an affordable housing model. Three case studies from Minneapolis, Santa Monica, and El Paso were examined using Terrapin’s Fourteen Patterns of Biophilic Design and the Living Building Challenge design guide. The analysis revealed that equity can operate through "place" (a Living Building Challenge imperative) and "connection to natural systems" (a Terrapin pattern). The study concluded that place and connection to natural systems have the potential to act as conduits to human and planetary equity.
