2023Moefty Mahendra, Sri Utami Dewi, Ajang Ramdani · JURNAL DIKDAS BANTARA · Indonesia
A qualitative descriptive study with 13 fourth-grade students at MIN 1 Karanganyar, Indonesia, found that the Adiwiyata program's greenhouse initiative was not running smoothly due to a lack of funds. The students' ecoliteracy in the "head" and "heart" aspects needed improvement, as most did not habitually sort waste despite knowing types, and some lacked empathy for plants. However, students demonstrated ecoliteracy in the "hands" aspect through proper cleaning tool use, bringing supplies from home, and saving electricity and water.

2023Wenhao Zhu · Highlights in Science Engineering and Technology · United States (Chicago)
This paper focuses on the characteristics of vertical farms, using The Plant vertical farm in Chicago as an example to describe its design and performance, and analyze its advantages and design principles. The success of The Plant is attributed to saving raw materials and waste disposal costs through waste utilization, staggered electricity consumption, and insulated structures to maximize energy cost savings. However, while small-scale pilot projects of vertical farms have achieved some success, many constraints remain for scaling them up due to high construction and operation costs and high technical levels.

2021Pratik Mishra, Sumit Vij · · India (Gurugram)
Ethnographic research in Budhera, a peri-urban village bordering Gurugram city in Haryana, India, investigated the juxtaposition of urbanization processes and climate variability impacts on peri-urban agriculture. Results showed that dimensions of agrarian livelihoods, such as cropping choices, irrigation cycles, sharecropping arrangements, declining common property resources, and land use changes to non-agricultural uses, were influenced by urbanization processes. It was concluded that changes in land and water use reshape agricultural practices and can cascade upon climate variability impacts, making agriculture more precarious for peri-urban farmers.

2019Martin Stuchtey, Tilmann Vahle · OpenEdition (OpenEdition) · Global
This paper discusses different types of urban agriculture (UA) to assess its potential for future food production. Conventional open-air farming is found to be rarely commercially viable for meaningful food production, though it offers community, educational, psychological, and environmental benefits. High-yielding Controlled Environment Farming (CEF), while potentially contributing substantially to food output, is highly capital and knowledge-intensive and likely to develop at city fringes due to economic considerations.

2019Michael Osei Asibey, Mohammed Abubakari, Charles Peprah · Cogent Food & Agriculture · Ghana
This paper investigated how urban farmers in Ejisu-Juaben Municipality, Ghana, cope with input and crop price fluctuations. Data from 380 respondents identified four major factors influencing input price volatility (oil prices, exchange rates, cocoa producer prices, and inflation), but farmers had no coping strategies for these. Crop price fluctuations were influenced by natural and demand/supply factors, and farmers coped by adding value to crops and diversifying income sources, among others. However, shifting to cocoa cultivation and farming in flood plains was shown to have adverse environmental and ecological implications.

2018S. Alan Walters, Karen Stoelzle Midden · Agriculture · Global
Vegetable production on green roofs faces multiple challenges, resulting in minimal current activity despite its potential for urban agricultural sustainability. While intensive green roof systems are considered suitable for vegetable production, extensive systems with shallow-rooted crops like lettuce, kale, and radish show the greatest potential for sustained productivity due to building weight restrictions. Deeper-root crops like tomatoes require constant monitoring of fertility and moisture. Green roofs are not presented as a total solution for urban food provision.

2018Robert McDougall, Paul Kristiansen, Romina Rader · Proceedings of the National Academy of Sciences · Australia
This study evaluated small-scale urban agriculture systems in Australia using economic and emergy (embodied energy) analyses. While these systems used land efficiently, they were relatively inefficient in their use of material and labor resources. Benefit-to-cost ratios demonstrated that, on average, the gardens ran at a financial loss, and emergy transformity was one to three orders of magnitude greater than many conventional rural farms. Only 14.66% of all inputs were considered "renewable," resulting in a moderate mean environmental loading ratio (ELR) of 5.82.

2018Khadija Benis, Rukaia Gashgari, Adnan Alsaati, Christoph Reinhart · DSpace@MIT (Massachusetts Institute of Technology) · Saudi Arabia (Riyadh)
The Urban Foodprints (UF) methodology was applied to assess the environmental sustainability of high-yield urban agriculture in Riyadh, Saudi Arabia, focusing on tomatoes. While urban production in high-yield greenhouses could reduce Global Warming Potential by 9% and water savings were significant, the energy needs of these greenhouses were considerably higher than the baseline. This indicates a trade-off where environmental benefits are partially offset by increased energy consumption.
