An experiment investigated the combined impacts of composted poultry manure (CPM) and inorganic fertilizers on tomato growth and yield under rooftop growing conditions. The experiment used a completely randomized design with eight treatments and three replications. NPK fertilizers alone and CPM combined with NPK fertilizers greatly improved tomato plant growth and fruit yield, with maximum yields (68 t ha-1) and economic benefits achieved with 4 t ha-1 CPM and 100% recommended doses of NPK fertilizers.

This study evaluated botanical insecticides as a technological device for synthetic input substitution in peri-urban horticultural systems of central Argentina. A Participatory Action Research (PAR) framework was used to assess the performance of garlic extracts (GE) for pest and natural enemy regulation in lettuce crops in conventional and agroecological contexts. Through three PAR cycles, GE effectiveness on aphids, thrips, and natural enemies was observed, and context-specific adaptations were noted: GE was useful near harvest in conventional systems and highlighted biodiversity's relevance for system redesign in agroecological systems.

This study reviewed 16 research papers on urban agriculture conducted at the Aranjuez Occupational Therapy Farm in Sucre, Bolivia, between 2016 and 2020. The review focused on agroecological practices in horticulture (37%), cereals and forages (31%), fruit growing (19%), and livestock production and soil improvement (13%). Findings indicate these practices contribute to local food security and sustainable agroecological approaches, with harvested products used by the therapy center itself. The study also highlighted both advances and limitations in adopting sustainable agricultural technologies in urban and peri-urban settings.

A literature search on nature-based solutions (NBS), including urban greenspaces and agriculture, found that 0%–3% of papers considered pollinators or pollination, with 12.5% in agricultural NBS papers. The study emphasizes that NBS success depends on resilient pollinator communities and calls for identifying keystone plants and pollinators to promote NBS functioning under future climatic conditions. It advocates for phylogenetic trait-based analyses to understand keystoneness.

This article explores vertical hydroponic farming, noting its benefits like reduced space and water use, and enhanced robustness with Plant Growth-Promoting Microorganisms (PGPMs). However, it also demonstrated that the system's ecological impact is significantly affected by growing media, pots, electricity use, and transportation. The study suggests potential for reducing greenhouse gas emissions and abiotic resource decline by using fiber as growing medium and paper containers.

This study investigated the effect of urban environmentally relevant concentrations of zinc in soils on nutrient exchange between arbuscular mycorrhizal fungi and pea plants using radio-isotope tracing. It found that at higher zinc concentrations, the transfer of phosphorus from fungi to plants and carbon from plants to fungi dramatically decreased. The results suggest that while urban horticulture has potential for food production, the unchecked presence of contaminants like zinc in urban soils may critically hinder its realization.

This four-year study in Ouagadougou, Burkina Faso, investigated the medium-term effects of repeated biochar, ECOSAN, and inorganic fertilization on urban vegetable production. Repeated biochar application at 20 t ha−1 increased soil organic carbon (SOC) by 51% under farmers' practice, while mineral fertilization alone decreased SOC by 32% and caused soil acidification. Biochar increased cabbage yield by 32% four years after application but had no effect on amaranth, and repeated application only benefited the first crop after reapplication.

An experiment in Giza, Egypt, during 2021/2022 and 2022/2023, evaluated celery growth and production in different substrate systems (pot vs. shallow beds) and planting densities (15, 18, 21 plants/m2). Celery grown in pots showed higher values for plant height, leaf number, root weights, head weight, and total yield per m2. For planting density, 15 plants/m2 resulted in the highest plant height, leaf number, root weights, and head weight, while 18 plants/m2 yielded a higher total yield per m2.

This mini-review discusses the extensive use of AB mix nutrients in Malaysian urban farming, noting their role in high yields but also their contribution to significant environmental pollution when overused. Although a survey of local entrepreneurs showed most complied with guidelines for chili plants, intensive use of fertilizers leads to nutrient leaching into the soil, causing environmental pollution and affecting humans, livestock, and microbial life. The review emphasizes the need for controlled nutrient application to prevent soil degradation and groundwater contamination.

This study investigated factors affecting compost maturity, specifically temperature, pH, and moisture content, by comparing breakdown rates of eight regulated combinations against an uncontrolled sample. The analysis showed that volume loss over time was critical for determining compost maturity. Combinations with high temperature and varying moisture/pH (High Temp, High Moisture, Low pH; High Temp, Low Moisture, High pH; High Temp, Low Moisture, Low pH) exhibited the most volume loss by day 46, indicating faster maturation than the uncontrolled group.

A pot experiment on a Charfasson town rooftop in Bhola, Bangladesh, assessed the effects of inorganic fertilizers and decomposed poultry litter on boro rice growth and yield. Eight treatments with three replications were used, measuring agronomic parameters every 30 days and yield after harvest. Treatment T7 (3.0 t poultry litter ha-1 + N100P25K90 kg ha-1) resulted in the highest plant height (82.67 cm at 90 days), leaf number (37.67 at 120 days), panicle length (27.17 cm), grains per panicle (153.33), rice yield (51.53 g/pot or 5.67 t ha-1), and B:C ratio (4.51). Treatments T7 and T8 showed statistically identical results, with T7 achieving the overall best performance.

This chapter presents insights on urban agriculture and the food-water-energy-waste nexus in the Middle East and drylands, drawing from seven years of experience in teaching, research, and stakeholder engagement at Qatar University. The arid climate, scarcity of freshwater and fertile land, and the need to reduce non-renewable energy use necessitate designing circular, integrated systems for maximum resource efficiency. The Living Laboratory at Qatar University and urban agriculture plans developed with students, researchers, and communities illustrate these integrative and regenerative approaches for resilient landscapes in Qatar and the Gulf region.

This chapter, based on 15 years of research, discusses key issues hindering urban agriculture from reaching its full potential for human and non-human health. It highlights shortcomings in urban planning policy, specifically the failure to recognize urban agriculture as food production, the invisibility of soil and lack of understanding of living soils, and the disregard for the advisory role of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can deepen urban agriculture's ambition in public spaces.

This paper develops a method to evaluate the integration of the water-energy-food (WEF) nexus into buildings when designing resilient cooling strategies. Applying the method to a case study, the highest WEF nexus index (77.54%) was achieved by combining urban agriculture, photovoltaic panels, and rainwater harvesting. The proposed framework helps decision-makers prioritize strategies that integrate all three resources to address building overheating and enhance resource efficiency.

This report discusses the barriers and drivers of Urban Agriculture (UA) within the framework of the Horizon 2020 project 'SiEUGreen,' across environmental, technological, economic, social/cultural, and regulatory/institutional aspects. Based on insights from five showcases in Norway, Denmark, Turkey, and China, the results suggest that city food provision and UA systems can be designed considering circular economy regenerative cycles. However, key barriers limiting UA uptake include the need for more evidence-based research, further experimentation for innovative technological developments, high investments, difficulties accessing financial support, underdeveloped business cases, limited recognition of UA's benefits, and behavioral/cultural barriers.
