Governance failureCommunityOrganic cyclePolicyMulti-Stakeholder Processes for Managing Wastewater Use in Agriculture
2009Alexandra Evans, Liqa Raschid-Sally, Olufunke Cofie · · Global
This chapter presents three case studies in which multi-stakeholder processes were used to improve wastewater management for urban agriculture. Although differences were observed, there were several cross-cutting lessons. A critical factor is the starting point, including an agreed definition of the problem to be addressed, negotiated goals, and a management structure acceptable to all stakeholders. When multi-stakeholder processes are externally initiated, it is essential that project priorities are commensurate with local priorities.

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.
