A literature review explored how learning gardens foster well-being and development through purposeful play in early childhood and beyond. Drawing on frameworks from self-determination theory, cognitive psychology, and developmental psychology, school gardens were shown to provide opportunities for purposeful play, supporting children's well-being, cognitive and identity development, and positive emotional experiences. Reported benefits in the literature include satisfying basic psychological needs of autonomy, competence, and relatedness, increased positive emotions, opportunities for cognitive and emotional renewal, and tangible evidence of student effort.

This overview, based on the ScienceDirect database, addresses heavy metal (HM) contamination in vegetables from urban and peri-urban areas. It notes that HMs like Cd, Pb, Hg, Cr, and As accumulate to toxic levels in the soil-plant-consumer continuum, causing health damage to consumers and physiological alterations in plants. Leafy and solanaceous vegetables accumulate the most HMs, while cucurbits and legumes are least affected.

The book "Urban soils. Principles and practice," edited by Andrew W. Rate, provides abundant information on the properties and functioning of urban soils, covering topics such as their genesis, spatial variability, functions, contamination, and remediation techniques. The book also details general soil science concepts and serves as a potential textbook. It notes that urban soils exhibit higher spatial variability than naturally formed soils, driven by human decisions.

This study, conducted in Erbil City in 2017 and 2020, measured the accessibility of public urban green spaces using network analysis with GIS. It found that for community parks, 68% of the population had access within 5 minutes travel time, while for mini parks, 22% had access within a 5-minute walk. This was the first known investigation into public green space accessibility in Erbil.

This study investigated the effect of different amounts of vermicompost (0%, 20%, and 40%) on Batavia lettuce cultivation. It found that 20% vermicompost accelerated germination on the first day (P0.05). By day 40, 20% vermicompost influenced plant height and leaf number, resulting in an average height of 5.44 cm and 7.2 leaves by day 46 (P<0.05). These findings suggest that 20% vermicompost is the most recommended amount for Batavia lettuce.

Auckland's urban sprawl threatens to significantly raise the price of fresh fruits and vegetables across the country, worsening chronic food security issues. Food production has become detached from the food security and food sovereignty of Aotearoa's people. The severity of this issue is driving calls for reform, and a conflict exists between humanity's agricultural subsistence and the destabilizing demands of financial extraction, where crucial productive hubs can be lost permanently.

This study aimed to gather information on the practical experience of young urban residents using urban horticulture and agriculture products, determine their readiness to practice such production independently in the future, and identify environmental benefits (ecosystem services) related to urban horticulture and agriculture indicated by respondents. A comparative study was conducted with students from 29 countries, including Brazil, China, India, Mexico, Poland, and seven EU countries. The collected data were used to compare approaches to urban horticulture and agriculture and their produce across different countries and cultural backgrounds.

This paper aimed to develop a conceptual framework for Life Cycle Cost (LCC) in the context of smart urban farming through an in-depth literature review. Employing the Iceberg Total Cost of Ownership (TCO) model, the conceptual framework for Smart UF LCC components was divided into acquisition cost and hidden cost. This framework assists in decision-making by providing a holistic view of the costs involved in a project or investment.

An experimental study at the Indonesian School of Kota Kinabalu, Sabah, Malaysia, introduced the "GREEN" urban gardening model to 34 high school students. The model, implemented through Project Based Learning, significantly improved students' knowledge scores from 64.85 to 76.77 and was found to effectively promote biodiversity, food, and learning experiences. Students perceived the model as engaging and user-friendly, contributing to enhanced activities and nutritional intake through fruits and vegetables.

This review paper provides an overview of passive cooling techniques, focusing on bio-mimicry design approaches adopted in global building design and construction. It highlights examples such as the East Gate Office building in Harare, which uses termite mound concepts, and the Vancouver Convention Center, which employs rooftop gardens for indoor temperature balance. The paper is limited to bio-mimic design approaches and suggests they offer significant solutions for building energy efficiency.

This article explores the environmental issues reflected in the experience stories of 16 gardeners and locals on Lucavsala island, Riga, collected through semi-structured interviews, observations, audio recordings, and photography in 2021. Gardeners expressed environmental awareness through narratives about the island's geography, gardening practices, and environmental quality, with acquiring and managing a garden being a prominent theme. Despite mentions of waste, the environmental quality of Lucavsala was generally judged to be relatively high, with fresh air, peace, and quiet being important indicators.

This exploratory review study examined the viability of urban food systems and their governance in Venezuela, based on secondary sources. While identifying available resources like educational infrastructure and a renewed legal framework, the study highlighted significant limitations. These include increasing deforestation, deteriorating potable water services for urban agriculture, migration of skilled populations, decline in public funding for science and technology, opaque official information, and scarcity of financing for new developments.

In allotment gardens and a second location in Graz, Styria, Austria, citizen scientists collected adult Aedes albopictus mosquitoes and eggs, which underwent morphological examination and DNA barcoding. A total of 217 eggs and 14 adult specimens were found, indicating that Aedes albopictus is already breeding in Graz. However, continued monitoring efforts are needed to determine if stable populations can survive there.

This study analyzed the efficiency performance and willingness to pay (WTP) for treated wastewater among 214 urban vegetable producers in the greater Accra metropolis of Ghana. Using data envelopment analysis (DEA) and logistic regression models, results showed that the current production system is technically inefficient, with 33% more output possible from existing resources. The mean amount farmers were willing to pay for treated wastewater delivered to their farms was GH¢66.7 per month.

An experiment was conducted for two seasons (2020/2021 and 2021/2022) at the Central Laboratory for Agricultural Climate's rooftop garden in Giza, Egypt, to determine suitable cultivation systems and planting densities for rooftop potato production. The deep beds system proved more suitable than the horizontal bags system, showing higher values for plant height, leaf number, and yield. While 6 plants/m² recorded the highest values for individual plant metrics, a density of 9 plants/m² resulted in the highest total yield per m².

This review emphasizes the Water-Energy-Food (WEF) Nexus as a tool to combat environmental degradation, address climate action, and achieve the Sustainable Development Goals (SDGs). It investigates the methodological paradigm and application of the WEF Nexus through case studies on water resources, energy efficiency, urban food production, food waste reduction, cross-sectoral perspectives, and the circular economy. The WEF nexus approach was found to stimulate multilevel and inter-sectoral governance, aiding in addressing complexities and inefficiencies in achieving the SDGs.
