Cities are restoring rivers to recapture the social, ecological, and economic benefits of rehabilitated rivers. But, traditional urban planning and flood management tools may not address the complex relationships between humans, the built environment, and natural elements in the social-ecological systems of which rivers are an important part. They also may not acknowledge and address the factors that led to channelization. The field of regenerative design and development—an eco-centric approach that aims to dismantle the underlying processes and viewpoints behind the most pressing environmental problems—offers tools to plan more effective and inclusive river restoration projects. To explore these issues and the potential of regenerative design and development, we reviewed 15 urban river restoration plans, followed by a comparative case study of the Los Angeles River, CA and the Kinnickinnic River, WI. We conducted a content analysis of plans and popular press articles, and interviewed key actors. Results indicate many participants exhibit regenerative thinking and participate in regenerative processes, but they are unable to fully implement regenerative projects due to several constraints at institutional, social, economic, physical levels. Study recommendations emphasize rooting restoration in the unique aspects of place, reframing projects as part of nested social-ecological systems, working from potential, addressing broader socioeconomic challenges, and leveraging strategic nodes. Changes to planning education and practice are needed to empower planners to think and act regeneratively.

For waste management in Asunción, Paraguay to improve, so too must the rate of public recycling participation. However, due to minimal public waste management infrastructure, it is up to individual citizens and the private sector to develop recycling solutions in the city. One social enterprise called Soluciones Ecológicas (SE) has deployed a system of drop-off recycling stations called ecopuntos, which allow residents to deposit their paper and cardboard, plastic, and aluminum. For SE to maximize the use of its ecopuntos, it must understand the perceived barriers to, and benefits of, their use. To identify these barriers and benefits, a doer on-doer survey based on the behavioral determinants outlined in the Designing for Behavior Change Framework was distributed among Asunción residents. Results showed that perceived self-efficacy, perceived social norms, and perceived positive consequences – as well as age – were influential in shaping ecopunto use. Other determinants such as perceived negative consequences, access, and universal motivators were significant predictors of gender and age. SE and other institutions looking to improve recycling can use these results to design effective behavior change interventions.

How we divide space in ever growing urban areas in an equitable, efficient and aesthetic fashion is one of the big questions of our time. In Lüneburg, Germany, citizens think more alternative forms of housing will be an important element of a sustainable future (Lüneburg 2030, 2018). Tiny Houses, dwellings that downsize an entire household to its minimum, are currently gaining attention in the country, but legal barriers make their implementation difficult. It has to be decided if legislations should be changed to allow these structures in the housing mix of Lüneburg. It is a difficult task to sift through the glamorization of Tiny Houses past the ideological utopia to see their value for the individual (Ansons, 2015). Therefore, it is of interest to fully understand what Tiny Houses offer for affordable housing stakeholders. Twenty-five evaluations of criticism and praise of the Tiny House Movement are collected by applying Q method, a tool to gather subjective viewpoints (Barry & Proops, 1999). Results indicate, four salient perceptions on that matter. Each viewpoint identifies different opportunities and risks when evaluating Tiny Houses for Lüneburg. This research demonstrates the potential of Tiny Houses to trigger participation by bringing people with diverse backgrounds together.
