Habitat connectivity shapes urban arthropod communities: the key role of green roofs
2014Braaker S., Ghazoul J., Obrist M.K., Moretti M. · Ecology, 95(4):1010-1021 · Switzerland (Zurich)
By sampling carabid beetles, spiders, weevils and bees on green roofs and ground-level green spaces in Zurich, this study compares community composition and tests the relative importance of local environment, microclimate and connectivity. Connectivity among roofs and to ground habitats emerged as a key driver of species composition, demonstrating that green roofs can act as stepping stones that support biodiversity in the surrounding urban ecosystem — a landmark case for connectivity-aware green-roof placement in city design.

2014Jürgen H. Breuste, Martina Artmann · Journal of Urban Planning and Development · Austria (Salzburg)
This study investigated how urban allotment gardens contribute to ecosystem services in Salzburg, Austria. A survey was conducted with 156 allotment gardeners across four allotment associations, focusing on the role of allotment gardens in recreation, food production, nature experience, ecological gardening, and environmental behavior. The results indicated the importance of allotment gardens for recreation and nature experience, alongside a declining importance of traditional food production. An increasing interest in ecological gardening and general environmental awareness among allotment gardeners was also observed.

2014Mabel Hernández Osorio, Ana Lid del Ángel Pérez, Carlos Nahin Castro José · Revista Biológico Agropecuaria Tuxpan · Mexico
This study in Veracruz, Mexico, identified insect pests associated with urban cultivation of vegetables and aromatic species in two types of recycled containers. Daily ethological monitoring revealed five insect pests: whitefly (Trialeurodes vaporariorum), red spider mite (Tetranychus urticae C.L.Koch), leaf miner (Liriomyza sp), thrips (Frankliniella occidentalis), and aphids (Myzus persicae). The findings aim to inform preventive actions and biological control strategies to reduce pest presence in urban container vegetable production.
BiodiversityDIYCommunityExploring the key factors to the success of the organic gardening for primary schools project and potential obstacles that may reduce the efficacy of such initiatives

2014Yu Wang · · China (Xi'an)
This paper constructed indicators for urban agricultural land use efficiency by incorporating urban agricultural ecosystem service indexes and evaluating their values in Xi'an city using the DEA method, analyzing temporal and spatial changes. Results showed that economic efficiency of agricultural land use gradually increased from 2010 to 2012, reaching 1 in 2011 and 2012, with social and eco-efficiency both in good conditions, indicating increasingly significant urban agriculture service functions. However, economic efficiency decreased spatially from urban core to suburban and rural areas, while social efficiency remained generally high, and eco-efficiency diminished from the city to surrounding counties.

BiodiversityFood educationCommunityUrban Land Use Decouples Plant-Herbivore-Parasitoid Interactions at Multiple Spatial Scales
2014Amanda E. Nelson, Andrew A. Forbes · PLoS ONE · Global
This study sampled two plant-herbivore-parasitoid systems across 250 sites in a 360 km2 urban/agricultural landscape to investigate the impact of human development on trophic interactions. It found that herbivorous insect densities were decoupled from host tree densities in urban landcover types at several spatial scales. Furthermore, a parasitoid species was absent from all urban/suburban landcover in one system, even where its herbivore host was common, indicating that human land use patterns limit specialist insect distributions due to dispersal constraints.

2014Haijian Feng, Zhongxue Zhou · Zhongguo shengtai nongye xuebao · China (Xi'an)
This study analyzed the spatial differentiation of urban agricultural functions in the Xi'an metropolitan zone, China, using ArcGIS grid technology at a 0.5 km × 0.5 km scale. Findings showed that production-economic function increased from southwest to northeast and from near-suburban to mid-far-suburban plains, while employment function was lower in the Qinling mountainous area than in plains. Cultural-leisure function exhibited a concentric spatial structure, and ecological function decreased from the urban periphery to the center, with severe fragmentation of ecological function value distribution areas.

2014Hannah Pitt · Area · Global
This paper proposes a methodology for more-than-human geography, focusing on understanding plants as agents through a "showing and being shown" approach. Drawing on ethnographic research in community gardens, the author demonstrates techniques like walking, talking, doing, and picturing to engage with human and nonhuman guides. The study identifies limits to understanding plants without specialist botanical training.

2014Anna Eugenia Alsobrook · · Senegal
This in-progress assessment investigates the Great Green Wall (GGW) reafforestation project in north-central Senegal, which aims to restore degraded land and improve local lives. Using field experiences, interviews, and observations, the study found that young GGW trees decreased land-surface temperatures and solar radiation, improving environmental conditions. While gardening and economic components showed positive village-level impacts, problems with water and grazing areas led to negative perspectives from stakeholders.

2014Jeremy Woodruff · Journal of sonic studies · United States (Pittsburgh)
This essay explores the contribution of sound art to progressive ecology groups in Pittsburgh, focusing on the installation "Gongburgh: Steeltown Forests" developed at the Hazelwood Food Forest (HFF). The composition, using sounds from the urban garden, gamelan, and steel factories, aimed to create social connections and promote the HFF through a sustainable music-making experiment. It highlights novel similarities and differences between these sounds and their social organization, raising political questions for the garden and listeners.

2014Yaw Kofi, Abena Adwoa, Kwasi Anane · Zenodo (CERN European Organization for Nuclear Research) · Ghana
Urban drainage systems in coastal Ghana are vulnerable to climate-induced flooding due to rising sea levels and increased rainfall intensity. Hydrological models indicated a need for increased stormwater infiltration capacity in ATMA, especially along the coastal belt where sea levels could rise by up to 50 cm. Designing drainage systems with enhanced permeability and elevated flood walls is recommended to ensure resilience against projected climate change risks over the next three decades.
