The Honeybee Man by L. Nargi
2011Sarah Mead-Willis · The Deakin Review of Children s Literature · United States (Brooklyn)
"The Honeybee Man" by L. Nargi is a 2011 picture book about Fred, a Brooklyn resident who keeps three honeybee colonies on his townhouse roof. The book illustrates Fred's urban beekeeping, showing how his bees collect nectar across the borough and how he harvests and distributes honey to neighbors. It aims to educate young families about local ecology and human community, explaining bee behavior and the processes of beekeeping and honeymaking.
DIYCommunityPollinatorsFood educationDeterminates of inner city butterfly and bee species richness
2010Kevin C. Matteson, Gail Langellotto · Urban Ecosystems · United States (New York City)
A study in community gardens in densely populated Bronx and East Harlem, New York City, evaluated local and landscape factors influencing bee and butterfly richness. Contrary to predictions, models showed that within-garden variables like floral area and sunlight availability were the most influential factors for both bee and butterfly richness. Marginal support was found for models of bee richness including the number of surrounding building units, which showed a negative association.
CommunityBiodiversityPollinatorsSmall scale additions of native plants fail to increase beneficial insect richness in urban gardens
2010Kevin C. Matteson, Gail Langellotto · Insect Conservation and Diversity · United States (New York City)
The ability of adding 70 plants of seven native wildflower species over two years to augment beneficial insect richness, including bees, butterflies, and predatory wasps, was assessed in New York City community gardens. Bayesian analyses failed to find a strong influence of the native plant additions on beneficial insect richness, even after correcting for prior floral abundance. Butterflies and megachilid bees were found to heavily utilize introduced ornamental and crop flowers in these gardens, even when native flowers were present.

2009Colla S.R., Willis E., Packer L. · Cities and the Environment (CATE), 2(1):4 · Canada (Toronto area)
A foundational study comparing bee diversity and abundance on green roofs and ground-level sites near Toronto. With suitable plants and management, green roofs can host bee communities comparable to ground habitats, discussing implications for urban pollinator conservation and rooftop agriculture.
PollinatorsBiodiversityCommunityBumble Bee Abundance in New York City Community Gardens: Implications for Urban Agriculture
2009Kevin C. Matteson, Gail Langellotto · Cities and the Environment · United States (New York City)
In 2005, a study compiled a list of crop plants in 19 New York City community gardens, classifying them by bee pollination dependence. Using mark-recapture methods, the abundance of the common eastern bumble bee (Bombus impatiens) was estimated. Wild populations of B. impatiens were found to be abundant in New York City community gardens, where it is the most prevalent native bee species and visits various crop flowers.
PollinatorsBiodiversityCommunityBumble Bees (Bombus spp) along a Gradient of Increasing Urbanization
2009Karin Ahrné, Jan Bengtsson, Thomas Elmqvist · PLoS ONE · Sweden (Stockholm)
This study investigated bumble bees in allotment gardens along an urbanization gradient from inner Stockholm to rural areas. Findings showed that bumble bee diversity decreased with increasing urbanization, from approximately eight species in rural areas to five to six species in urban allotment gardens. Higher variability in the abundance of certain species in the most urban areas suggested a potentially weaker reliability of the pollination ecosystem service in areas strongly influenced by human activity.
Environmental trade-offsBiodiversityPollinatorsCommunityPeri-urban agricultureEditor's Introduction - Urban Pollinators and Community Gardens
2009Eric G. Strauss · Cities and the Environment · Global
This issue of CATE is dedicated to the theme of urban pollinators in relation to community gardens, addressing a gap in knowledge regarding pollinator ecology in urban landscapes. It notes that while pollinators' roles in agricultural systems are well-studied, their impact in community gardens is less understood. Six papers in this issue explore these questions, aiming to provide a foundation for understanding urban pollinators and guiding future research and management.
PollinatorsBiodiversityCommunityModification of a Community GArden to Attract Native Bee Pollinators in Urban San Luis Obispo, California
2009J. C. Pawelek, Gordon W. Frankie, Robbin W. Thorp, Maggie Przybylski · Cities and the Environment · United States (California)
A community garden in San Luis Obispo, California, was modified by planting bee-attractive plants to attract native bee pollinators. Garden modification and monitoring of native bees occurred from 2007 through the 2009 growing season. The diversity of collected and observed native bees increased each year, with 40 species in 17 genera recorded to date.

2008Stephan Barthel, Carl Folke, Johan Colding · · Sweden (Stockholm)
This thesis investigated how social-ecological features influence ecosystem service (ES) generation through case studies in Stockholm, Sweden. Findings indicated that urban ES flows are products of co-evolutionary processes, requiring governance to consider historical rights and diverse actor groups. Informally managed allotment gardens showed higher pollinator abundance compared to other urban green spaces, and social-ecological memory among gardeners was found to retain and transmit practices linked to ES generation. The study concluded that sustaining urban ES depends on management practices by people and local communities of ecosystem practice.

2008Henrik Ernstson, Stephan Barthel, Erik Andersson, Sara Borgström · · Sweden (Stockholm)
This thesis investigates social-ecological features shaping the generation of ecosystem services (ES) in the urban landscape of Stockholm, Sweden. Through interdisciplinary case studies, it showed that informally managed allotment gardens have a higher abundance of pollinators, and voluntary actor groups motivated by a sense-of-place support ES generation. Social-ecological memory among allotment gardeners retains and transmits practices linked to ES, suggesting that sustaining urban ES requires considering historical property rights, diverse actor groups, and local communities of ecosystem practice.
BiodiversityPollinatorsCommunityPolicyRecognizing Ethiopia's urban farmers.
1993Lee M · PubMed · Ethiopia
In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.
