Abstract

The urgent need to address sustainability challenges in food, water, and energy (FWE) has led to the FWE Nexus framework. Ensuring food security and sustainable urban agriculture are critical elements of sustainable development. Community gardens (CG) have gained prominence as they enhance food production, foster social cohesion, and mitigate environmental impacts. This study investigates CGs’ land usage using a system dynamics modeling approach based on data from a case study at Concordia University’s Loyola Campus Garden. Simulations were done using the Vensim Software. The objective is to analyze land usage in response to various CG scenarios: (1) harvesting ratio on dedicated CG land, (2) production efficiency by involving experienced farmers, and (3) cost considerations.

The findings reveal insights into CGs’ potential for sustainable development. More CG land leads to increased local food production, impacting food security positively. Improving CG efficiency enhances their role in addressing food-related challenges. However, financial considerations must be balanced for long-term viability and scalability.

The study aligns with the United Nations Sustainable Development Goals (SDGs). Evidence supports CGs’ contributions to SDG 2 (Zero Hunger), SDG 3 (Good Health and Well-being), SDG 11 (Sustainable Cities and Communities), and SDG 12 (Responsible Consumption and Production). Policymakers, planners, and community organizers can leverage insights to promote sustainable urban agriculture and achieve development objectives.

Furthermore, this study highlights CGs’ importance in the FWE Nexus framework and their potential for sustainable development. Understanding land usage dynamics allows informed decisions to enhance food security, foster communities’ well-being, and promote responsible consumption in urban areas.
