Native and non-native plants attract diverse bees to urban gardens in California
2019Gordon W. Frankie, Ingrid Feng, Robbin W. Thorp, Jaime C. Pawelek, Marissa H. Chase, Christopher C. Jadallah, Mark Rizzardi · Journal of Pollination Ecology · United States (California)
An extensive survey of bee-flower collection records from 10 California cities between 2005 and 2011 examined diverse bee species visiting native and non-native ornamental plants. A total of 7,659 bees were examined, identifying 229 bee species visiting both native and non-native plant types. Native bee species were common on both plant types, but substantially more non-native bee species visited non-native plants compared to native plants.
BiodiversityPollinatorsCreating the Urban Farmer’s Almanac with Citizen Science Data
2019Kathleen L. Prudic, J. Keaton Wilson, Michelle C. Toshack, Katharine L. Gerst, Alyssa Rosemartin, Theresa M. Crimmins, Jeffrey C. Oliver · Insects · Global
This study introduced web-based citizen science programs to assist urban growers in managing insect biodiversity on city farms, a complex task given the estimated 30% of the global urban population engaged in food production. The programs aim to connect growers with relevant data and experts for informed insect management decisions. It suggests that combining citizen science volunteers with urban farmers can clarify ecosystem services, reduce insecticide use, and promote non-chemical alternatives.
CommunityBiodiversityPollinatorsAssessing Urban Ecosystem Services
2019Marise Barreiros Horta, Maria Inês Cabral, Iva Pires, Laura Bachi, Ana Luísa Luz, Geraldo Wilson Fernandes, Maria Auxiliadora Drumond, Sónia Maria Carvalho Ribeiro · IGI Global eBooks · Global
This chapter summarizes different participatory approaches for assessing ecosystem services (ES) in urban areas across three countries. In Belo Horizonte, Brazil, a conceptual framework for vacant lots ES assessment was presented. In Leipzig, Germany, a combination of site surveys, interviews, and remote sensing was utilized for a comparative study between two forms of urban gardening. In Lisbon, Portugal, the study provided social insight into horticultural parks based on interviews. Overall, these studies demonstrate the potential benefits of utilizing ES assessment approaches on urban landscapes, particularly for better understanding the interactions between people and nature in urban sites.

2019Uvianeth Castañeda Maldonado · · Colombia (Bogotá)
The recognition and characterization of arvense flora (weeds) found in urban gardens assisted by the Bogotá Botanical Garden in Bogotá, Colombia, were conducted. A catalog of arvense recognition for the Capital District was developed, representing 36 species of weeds belonging to 15 families of the Magnoliopsida class. This catalog includes photographic records, field observations, and information on pollinator presence, serving as an important consultation tool for the district's flora.

2019Kimberly M. Ballare, John L. Neff, Rebecca Ruppel, Shalene Jha · Ecological Applications · United States
This study assessed bee community composition at 20 grassland and 20 agriculture sites across two US metroplexes over three time periods, identifying 172 species from nearly 13,000 specimens. It found that regional land use differentially impacted bee abundance and diversity depending on local habitat management. Local bare ground and floral richness were significantly related to multiple metrics of bee diversity.
BiodiversityPollinatorsUrban–rural linkageWild Bee Conservation within Urban Gardens and Nurseries: Effects of Local and Landscape Management
2019Monika Egerer, Jacob M. Cecala, Hamutahl Cohen · Sustainability · United States (California)
This study compared the effects of local and landscape features on wild bee species abundance and richness in 19 gardens and 11 nurseries in California, USA. Local features such as floral richness and ground cover, and landscape features like impervious land cover, were assessed. In gardens, floral richness, local habitat size, and urban land cover impacted wild bee species richness, while in nurseries, floral richness and the proportion of native plant species impacted wild bee abundance and richness.

2019THAYZA DE OLIVEIRA BATITUCCI, Erika Cortines, Fábio Souto Almeida, Ângela Alves de Almeida · Ambiente & sociedade · Brazil (Rio de Janeiro)
This study analyzed the interactions of agricultural activities and the urban ecosystem through a literature review and a case study of an Urban Agriculture program in the metropolitan area of Rio de Janeiro, Brazil. It found that urban agriculture provides considerable ecosystem services, generates income, increases biodiversity conservation, and fosters social inclusion. The research concludes that urban agriculture functions as a mechanism for achieving equilibrium among the components of the urban ecosystem.

2019M. Tsuruta, Kyo Itoyama · Japanese Journal of Applied Entomology and Zoology · Japan (Kawasaki City)
This study investigated the seasonal occurrences and species composition of Orius spp. in an okra field in Kawasaki City, Japan. Orius spp. were found on okra plants from early-summer to early-autumn, with peak occurrences advancing with earlier flowering times. The initial occurrence was not associated with the seasonal prevalence of thrips on okra plants, suggesting that the main factors influencing Orius spp. occurrence are prey-independent.

A study was conducted in the Vial Colon organoponics system in Pinar del Rio municipality, Cuba, to determine the diversity of arboreal species. Inventories were performed in each organoponics system to count individuals per species, followed by taxonomic identification and calculations of absolute frequency and abundance. The research identified 37 arboreal species belonging to 26 botanical families, with Fabaceae being the most represented and Persea americana Mill. and Moringa oleifera Lam. being the most abundant.
BiodiversityCommunityEVALUACIÓN DE LA CALIDAD DEL SUELO DE UN HUERTO URBANO EN XALAPA, MÉXICO.
2019Yadeneyro de la Cruz Elizondo, Juan Camilo Fontalvo-Buelvas · Suelos Ecuatoriales · Mexico (Xalapa)
In an urban green area in Xalapa, Mexico, soil quality was evaluated prior to the implementation of a university garden. The soil was brown and sandy loam with poor aggregate stability and a bulk density of 2.52 g/cm3. Biologically, earthworm density was poor at 67.2 ind/m2 and the number of edaphic groups was poor at 5, though pH was optimal at 6.58 and organic matter was medium at 6.45%. Overall soil quality was assessed as moderate, indicating a need for an integrated soil management plan for improvement.

2019К. Г. Ткаченко · HORTUS BOTANICUS · Global
Botanical institutions should create and maintain diverse plant collections, including local flora, ethnobotanical knowledge, and carpological collections, for research and education. These collections can inform urban gardening and floristics, but it is crucial to evaluate the invasive potential of introduced species to prevent their spread in the region's flora.

2019Nina Gren · Lund University Publications (Lund University) · Sweden
This presentation, based on ethnographic research from 2017-2018 in the Malmö-Lund area, Sweden, examines creativity in urban gardening projects as a response to ecological crisis. Urban gardeners, particularly project coordinators, expressed concerns about ecological emergency and sought to promote sustainable living. They developed creative events and workshops for children, including storytelling, planting, harvesting, and making 'bee hotels', to educate them on ecological issues and inspire aspirations for a different future.

2019Odiney Alvarez‐Campos, Gregory K. Evanylo · Journal of Environmental Quality · Global
The impacts of exceptional quality (EQ) biosolids and inorganic fertilizer applied for rehabilitating anthropogenic soils on potential nitrogen (N) and phosphorus (P) water quality impairment risk were compared. After two years, reclamation rates of biosolids resulted in soil P saturation ratios greater than the recommended 30% but lower than the 65% limit. While nitrate N (NO3–N) posed the greatest nutrient leaching risk, lysimeter-collected mass loading of NO3–N from reclamation rates was not greater than for the inorganic fertilizer.

This study in Surabaya, Indonesia, aimed to identify urban farming models, community motivations, and obstacles faced in implementing urban agriculture. The study found that the most common urban farming models were hydroponics, followed by verticulture, fisheries, and rooftop gardens. Community motivations primarily included increasing income, utilizing empty land, pursuing farming hobbies, and using green open spaces. The main obstacles faced by the community were plant pests, lack of capital for development, extreme weather, and insufficient experience and knowledge in urban agriculture.
