Strategies for Mainstreaming Edible Cities with Focus on the City of Lincoln: A Critical Cross-Case Study Analysis of Community Growing Groups in the UK

Urban Science, Journal Year: 2025, Volume and Issue: 9(1), P. 7 - 7

Published: Jan. 2, 2025

The socio-political climate in the UK, compounded by government austerity measures, has intensified cost-of-living crisis, significantly impacting affordability of food supply chain. This led to an increasing disconnect from healthy dietary practices and contributed declines mental physical wellbeing. paper examines role edible city (EC) initiatives addressing these challenges enhancing security, fostering social resilience supporting community aim this research is understand tangible links between EC mechanisms how they align with local, cultural geographical perspectives. Focusing on City Lincoln, study aims develop a contextualised framework that culturally geographically relevant aligns global goals for sustainable urban development as outlined United Nation’s Sustainable Development Goal 11 (SDG11), promoting inclusive, environmentally safe economically viable communities. Utilising mixed methods approach, combines qualitative interviews critical cross-case analysis four growing groups alongside quantitative socio-demographic data analysis. findings reveal successful adapt their environment socio-cultural conditions highlight importance diversification long-term sustainability. Four core themes emerged across case studies: (1) prescribing, (2) capital (3) knowledge sharing (4) value. These inform creation novel flexible framework, providing actionable insights policy recommendations support regeneration enhance resilience. contributes transferable strategies diverse contexts, pathway toward resilient socially cohesive environments.

Oral bioaccessibility trends for As, Cd, Cr, Ni, and Pb in vegetables grown in contaminated soils: A systematic review

Urban Agriculture & Regional Food Systems, Journal Year: 2025, Volume and Issue: 10(1)

Abstract Urban and peri‐urban agriculture has the potential to address social, economic, environmental issues by bringing communities together, producing low‐cost food, greening derelict locations. However, many urban brownfield sites have a legacy of soil metal metalloid contamination, so crops grown on these may pose risks human health. This review uses orally bioaccessible fractions (BAFs) common contaminants observed in vegetables across literature produce hierarchies relative ingestion according potentially toxic element (PTE), vitro test, vegetable type. will inform health risk assessment linked consuming PTE‐contaminated land identify areas where further research is required. BAF values were obtained from relevant collected multiple online databases, for range PTEs, test methods, types. Overall, median PTE BAFs ranked as: Cd > Ni Cr As Pb. Across tests, unified BARGE method (UBM) reported highest when assessing all PTEs (median 63.0% G 59.6% GI). Median crop as follows: non‐vegetables, example, rice/fungi legumes root bulb leaf. These results site design agroecosystems mitigate risks.
