It is often argued that growing one's own food reduces household food waste by raising appreciation of food, but focused research on this is lacking. Using thematically analysed qualitative surveys with a privileged sample of food gardeners, this study finds the relationship more complex than proposed: for these gardeners, growing their own food can also decrease appreciation of food and create waste because of the challenges of growing, processing and storing it. Food gardening could nonetheless become an instrumental waste-prevention practice if growing is made easy and convenient, gardeners are given opportunities to work together, more channels exist for sharing surplus, and cooking skills improve. Its contribution is to critique the assumption that growing your own always leads to appreciation of food and less waste.

Set against urbanisation that has cut farmland and limited access to fresh vegetables, this study evaluates garden towers as a vertical landscape element for community-based vegetable production. Using a descriptive-evaluative approach, it assesses 105 garden-tower units distributed to 21 women farmers groups in and around Bogor, Indonesia, and discusses their contribution to food availability and social-ecological resilience in dense settings.

A transdisciplinary research project investigated reusing treated kitchen wastewater for irrigating edible vegetable production in households. The project developed a prototype with an engineered biological filter to reuse dishwasher wastewater for growing vegetables and ornamental plants for domestic use. This approach aims to reduce water and fertilizer consumption, enabling the production of healthy, safe, and local food.

This study, conducted in 2022-2023 at Zagazig University, Egypt, proposed and evaluated three rooftop garden designs for a college campus using 3D software, with assessments from specialists and users. Results indicated that 100% of specialists and 91.7% of users preferred flowering herbaceous plants, while trees and palms were preferred by 60% of specialists and 48.6% of users. Overall satisfaction with proposed designs for human senses ranged from 69.4% to 75.7%, and agreement on suitable recreational areas ranged from 65.8% to 78.4% among users.

This research modeled phenolic compound distribution in eight flaxseed genotypes cultivated in the Sobat River Floodplain during the 2023 season. Total phenolic content ranged from 8.4 to 16.7 mg gallic acid equivalents per g dry weight, with the seed coat contributing 64.2% of free phenolics. Urban gardening trials showed composting-amended substrates increased total phenolics by 13.8%. A predictive model explained 72.3% of total phenolic variance, and supply chain simulations indicated 8.6% phenolic losses over 60 days.

This study investigated millicompost as a sustainable peat-alternative substrate for bell pepper seedling production, combining it with regional agro-wastes like coconut coir, gliricidia shavings, and elephant grass. Seven novel growing media formulations were tested. Substrates S4 (33% millicompost + 33% gliricidia + 33% coconut fiber) and S8 (50% millicompost + 50% gliricidia) produced seedlings of similar quality to pure millicompost and commercial substrate.
