This study examined the contribution of residential gardens to ecosystem services in Trabzon City, Turkey. It was determined that both spatial needs and ecosystem benefits can be met with the same Green Infrastructure (GI) elements, and landscape value is supported by GI elements such as edible gardens, pollinator gardens, rain gardens, biological ponds, and green roofs. GI elements combining vegetation and water landscape elements have a higher potential for ecosystem services. The study concluded that green areas of residential gardens should be planned and designed through a holistic GI-oriented approach based on the total building parcel.

This paper explores urban farming models and their role in climate change adaptation within urban environments, drawing on the SATURN project's collaboration across Gothenburg (Sweden), Trento (Italy), and Birmingham (UK). It presents Gothenburg's entrepreneurial model, where municipal management leases allotments to farmers to scale businesses and provide sustainable food. Trento combines bottom-up and institutional processes to foster short local supply chains, potentially benefiting from a land lease scheme. Birmingham's model views urban farming primarily as community support for mental health and awareness, rather than an entrepreneurial activity. The research demonstrates how abandoned and underutilized land can be regenerated through these diverse European urban agriculture models.

This article explores three types of climate change activism expressed through urban agriculture: 'proximities', 'disruptive dissent', and 'participatory urban governance'. It analyzes how urban agriculture, as a form of grassroots climate change activism, can help in taking action, using illustrative examples from Bristol, UK, and Lisbon, Portugal. The paper suggests that citizens are exploring ways to participate in combating climate change by changing economic and productive systems in their daily lives and lifestyles.

This study examines strategies for integrating agriculture with the city of Kirklareli, Turkey, and its surrounding area to address problems arising from rapid population growth and irregular urbanization, using a four-stage method. Following a literature review, it collected and examined natural and socio-cultural data for the province, identified through field observation which neighborhoods were most suitable for applying an urban agriculture model, and set out implementation strategies and recommendations aimed at human health, environmental health, food safety, urban aesthetics, social integration and urban sustainability.

Emanuele Sommariva, Nicola Canessa, Giorgia Tucci · DOAJ (DOAJ: Directory of Open Access Journals) · Europe

An article links the role of ecosystem services to growing research and development funding attention to green infrastructure and urban greening strategies, positioning ecosystem services as a new parameter for assessing urban green infrastructure and re-naturalization processes that counteract climate-change effects such as flooding and heat islands while promoting conservation, resilience, and biodiversity of natural habitats. It identifies urban agriculture and community gardens as playing an important role in securing socio-ecological benefits at the local level and promoting access to healthy, "Zero Km" food sources. Drawing on the European project Creative Food Cycles, the article outlines ideas for circularity and recycling of waste across the food chain.

This paper analyzes Thomas Kling’s poem „geschrebertes idyll, für mike feser“ as an "allotment garden idyll" within 'new nature poetry'. While Kling skillfully engages with the idyll genre and offers ecological, social, medial, and historical critique, the study finds that he presents a decidedly patriarchal self-image, which contemporary readers would likely find less acceptable.

Sandra Schwindenhammer, Denise Gonglach · Politics and Governance · Germany

This qualitative and participatory case study in Germany examined the governance implications of an emerging technology in urban agriculture that connects wastewater treatment and agricultural production for urban hydroponics. The analysis found that while this technology has the potential to facilitate SDG implementation, it simultaneously creates new sector interlinkages between water and food, leading to policy demands that necessitate more integrated policymaking.

Fabio Amato, Lucia Simonetti · Journal of urban regeneration and renewal · Italy (Naples)

This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

Green infrastructure refers to an interconnected network of natural or semi-natural areas whose proper functioning generates benefits for human societies and strengthens their resilience. It can simultaneously produce multiple benefits such as improved stormwater management, creation of cool islands and species habitats, job creation in urban agriculture, economic valuation of real estate, and new nature experiences. Green infrastructure allows for the reinvention of urban landscapes and a reconsideration of our intimate relationship with living things.

This study addresses knowledge gaps in selecting plant species and understanding landscape heterogeneity's role in dispersal success for Green Infrastructure (GI) planning. It suggests a methodological approach for fine-scale assessment in peri-urban agricultural landscapes, using a case study in the Metropolitan City of Rome. The approach involved stratifying the area, defining GI components, characterizing the area with Morphological Spatial Pattern Analysis, assessing connectivity, and prioritizing conservation measures. Despite recognized limits, the approach proved functional for the context and detail level.

Felipe Parada, Xavier Gabarrell, Martí Rufí-Salís, Verónica Arcas‐Pilz, Pere Muñoz, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)

This study investigated the agronomic performance and environmental life cycle impacts of three different fertigation management practices (open, 30% recirculation, and recirculation with a further 15% fresh water reduction) for tomato crops in a rooftop greenhouse in Barcelona. All three practices resulted in similar yields, but the recirculation with reduced fresh water input was the most water-efficient, requiring 48.7 liters per kg of tomato. In terms of environmental performance, the recirculation practice showed the best performance in most impact categories, particularly in marine and freshwater eutrophication, with 44% and 93% fewer impacts than the open management.

This study provides a national-scale analysis of the horticultural production potential of urban green spaces in Great Britain (GB). It identifies urban green spaces available for horticultural production and quantifies potential yields based on three production options. Urban green spaces in GB, at their upper limit, have the capacity to support production 8 times greater than current domestic fruit and vegetable production, or 38% of current domestic production and imports combined. Most urban green spaces consist of private residential gardens and amenity spaces, and all examined towns and cities were found to have substantial potential to meet the dietary needs of the local urban population.
