This study assessed the impact of peri-urban agriculture on food self-sufficiency in Faisalabad, Pakistan, by collecting data from 100 peri-urban farming households and analyzing land use changes from 2018 to 2023 using GIS. Households allocated an average of 12.9 Kanals for seasonal vegetables, consuming nearly half domestically and selling the rest locally. A significant association was found between positive nutritional perceptions and regular access to fresh produce. However, limited government support, weak stakeholder coordination, and inadequate market access were identified as key barriers limiting its broader impact.

This qualitative study compares three Swiss communal agricultural prosumption (CAP) types: allotment gardens (AGs), community gardens (CGs), and community supported agriculture (CSA), using Grounded Theory. It found that community-centred CAPs (CSAs, CGs) generate political agency but face financial barriers limiting participation. Individual-centred CAPs (AGs) offer autonomy but have high knowledge requirements and lack political leverage, posing crucial challenges for long-term viability. The study concludes that targeted policy and institutional strategies are needed to ensure the continuity of all CAP types.

This Note argues that municipalities in the United States should permit on-site slaughter of backyard chickens on private residential property. Historically, local governments codified the separation of residential and agricultural uses, leading to bans and restrictions on urban agriculture. The current regulatory vacuum for urban agriculture creates conflicts and uncertainties, and allowing backyard slaughter could strengthen local food systems and regulate a growing urban practice.

Ylva Wallinder, Maria Langa · Environmental Sociology · Sweden

A study investigated the consequences of institutional policy change on urban gardening practices in Swedish municipalities over the last decade. Local sustainability policies have led to an increasingly business-centered model, which clashes even with entrepreneurial gardens. This shift caused associational gardening to give way to an extended focus on entrepreneurship and food production, representing a "green rationalization" of gardening practices in urban sustainability policies that hinders their sustainability potential.

A critical GIS analysis was conducted for Sydney and neighboring regions in NSW, Australia, to understand and advocate for Sydney's food production capacity. The study challenged the notion that Sydney's metropolitan landscape has low inherent biophysical quality for agriculture. Despite current metropolitan planning policy that marginalizes agricultural productivity, datasets revealed western Sydney is biophysically well suited for agriculture. Sydney's overall agricultural capacity was found to be comparable to five of six other coastal regions of NSW and superior to at least two, challenging current planning orthodoxy and policy.

This study evaluated the role of urban agriculture (UA) in enhancing post-disaster food security in Wellington, New Zealand, a region highly prone to earthquakes. It calculated vegetable self-sufficiency by mapping potential productive land, estimating vegetable yields, and assessing post-disaster food demands across multiple scenarios. Potential productive land accounted for 0.3% to 1.5% of the total area, primarily distributed in the eastern part of the city. Results indicate that Wellington's vegetable self-sufficient rates through UA range from 3% to 75%, with higher rates for displaced and vulnerable populations. Realizing this potential will require stronger policy support and integration with urban planning and disaster preparedness.
