BiodiversityClimate changeEconomicsBumble 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.

2009Andreas Buerkert, Eva Schlecht, Martina Předotová, Rodrigue V.C. Diogo, Katja Kehlenbeck, Jens Gebauer · eScholarship (California Digital Library) · Sub-Saharan Africa
This study analyzed urban and peri-urban agriculture (UPA) systems in major Sub-Saharan African cities, measuring carbon, nitrogen, phosphorus, and potassium fluxes and conducting biodiversity studies. In Niamey, low-input gardens showed annual gaseous carbon emissions of 20-25 t ha-1, predominantly CO2, and high-input gardens irrigated with wastewater had annual CO2-C emissions of 27 t ha-1, with N2O as a major nitrogen loss contributor. Animal manure stored in the open was subject to large carbon and nitrogen losses, indicating environmental tradeoffs. However, UPA gardens in Niamey maintained a large variety of fruit and vegetable species, with richness increasing with garden and household size and commercialization.

2009Ana Puertas, L Hidalgo-Díaz · Revista de Protección Vegetal · Cuba
An experiment in Cuba investigated the effect of different organic fertilizers on the establishment of the biological control agent Pochonia chlamydosporia var. catenulata in the substrate and rhizosphere of tomato plants. High colonization levels of the substrate and tomato roots were observed across all treatments using soil, cattle manure, and worm humus in various proportions. Results indicated a tendency for higher root colonization values in organic fertilizers and proportions that allowed medium or lower substrate colonization. Both organic fertilizers can be used to support the application of P. chlamydosporia var. catenulata in urban agriculture.

Climate changeBiodiversitySocial-ecological memory for management of ecosystem services
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.

CommunityBiodiversityEcological scales and social network structure in urban landscapes: management and governance of urban ecosystem services in Stockholm, Sweden
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.

2008S. Karrie Reid, Lorence R. Oki · California Agriculture · United States (California)
In California, there is a growing need for landscape plants requiring fewer water and chemical inputs. A program at UC Davis screened ten unused or underused California native plants for low water tolerance in open-field conditions during summer 2006. No significant differences were found in summer growth or physical appearance across four irrigation levels. Six species maintained a favorable appearance throughout the season and are now undergoing further assessment in demonstration gardens across seven climate zones.
CommunityClimate changeBiodiversityCommunity resilience and contemporary agri‐ecological systems: reconnecting people and food, and people with people
2008Christine King · Systems Research and Behavioral Science · Global
This paper explores how agri-ecological systems such as Organic Agriculture, Biodynamics, CSA, Permaculture, Farmers Markets, and Community Gardens contribute to agri-ecological and community resilience. These systems contribute to more sustainable and resilient communities through community development processes like relationship building, genuine participation, inclusiveness, resource mobilization, and creating space for knowledge sharing. The paper compares ecological systems models to agri-ecological systems and suggests how ecological systems theories might contribute to the future of community-based agri-ecological resilience.
