Adaptive urban development is the design, construction and continuing evolution of urban areas to anticipate and react to changes in the environment and society. These changes include both processes within the city itself and external developments. It is expected that until 2100 a total of 5 billion people will move to cities. Per day this means a 150,000 people start to live in a city. In the same period resources such as fossil fuels, fresh water resources, phosphates and fertile topsoil are running out. This unprecedented urbanization process will convert a large part of the fertile croplands in urban areas. At the same time the food demand from this shrinking productive area will double due to population increase and rising living standards. Most of the urbanization will take place in vulnerable delta areas. To create a perspective to deal with this huge challenge in the 21st century, two things are needed. First, the current parasite cities need to transform into flood proof ecocities. Transforming the existing cities, however, will not be enough to deal with the challenges the world is facing. The second component of the strategy therefore means that a part of the cities and food production should be located on the water to create more space. Rutger de Graaf is civil engineer, entrepreneur and researcher. At the Rotterdam University of Applied Sciences he works as professor Adaptive Urban Development. He is also director and founding partner of DeltaSync, a leading international floating urbanization specialist, and editor of the Journal of Water and Climate Change at the International Water Association.

What is this publication about?
In this publication on ‘New urban economies’,
we search for answers and insights to a key
question: how can cities foster economic
development and develop ‘new urban economies’.
And, importantly, how can they do that:
◗ in concertation with different
urban stakeholders, ◗ responding adequately to key challenges
and developments beyond their control, ◗ building on the cities’ own identity,
industries and competences, ◗ in a sustainable way, ◗ and without compromising
weaker groups.

Limited data is available on the size of urban goods movement and its impact on numerous aspects with respect to livability such as emissions and spatial impact. The latter becomes more important in densifying cities. This makes it challenging to implement effective measures that aim to reduce the negative impact of urban good movement and to monitor their impact. Furthermore, urban goods movement is diverse and because of this a tailored approach is required to take effective measures. Minimizing the negative impact of a heavy truck in construction logistics requires a different approach than a parcel delivery van. Partly due to a lack of accurate data, this diversity is often not considered when taking measures. This study describes an approach how to use available data on urban traffic, and how to enrich these with other sources, which is used to gain insight into the decomposition (number of trips and kilometers per segment and vehicle type). The usefulness of having this insight is shown for different applications by two case studies: one to estimate the effect of a zero-emission zone in the city of Utrecht and another to estimate the logistics requirements in a car-free area development.

This paper examines how a serious game approach could support a participatory planning process by bringing stakeholders together to discuss interventions that assist the development of sustainable urban tourism. A serious policy game was designed and played in six European cities by a total of 73 participants, reflecting a diverse array of tourism stakeholders. By observing in-game experiences, a pre- and post -game survey and short interviews six months after playing the game, the process and impact of the game was investigated. While it proved difficult to evaluate the value of a serious game approach, results demonstrate that enacting real-life policymaking in a serious game setting can enable stakeholders to come together, and become more aware of the issues and complexities involved with urban tourism planning. This suggests a serious game can be used to stimulate the uptake of academic insights in a playful manner. However, it should be remembered that a game is a tool and does not, in itself, lead to inclusive participatory policymaking and more sustainable urban tourism planning. Consequently, care needs to be taken to ensure inclusiveness and prevent marginalization or disempowerment both within game-design and the political formation of a wider participatory planning approach.

Comprehensive understanding of the merits of bottom-up urban development is lacking, thus hampering and complicating associated collaborative processes. Therefore, and given the assumed relevancies, we mapped the social, environmental and economic values generated by bottom-up developments in two Dutch urban areas, using theory-based evaluation principles. These evaluations raised insights into the values, beneficiaries and path dependencies between successive values, confirming the assumed effect of placemaking accelerating further spatial developments. It also revealed broader impacts of bottom-up endeavors, such as influences on local policies and innovations in urban development.

The emergence of organic planning practices in the Netherlands introduces new, non-conventional, local actors initiating bottom-up urban developments. Dissatisfied with conventional practices and using opportunities during the 2008 financial crisis, these actors aim to create social value, thus challenging prevailing institutions. Intrigued by such actors becoming more present and influential in urban planning and development processes, we aim to identify who they are. We use social entrepreneurship and niche formation theories to analyse and identify three types of social entrepreneurs. The first are early pioneers, adopting roles of a developer and end-user, but lacking position and power to realize goals. Secondly, by acting as boundary spanners and niche entrepreneurs, they evolve towards consolidated third sector organizations in the position to realize developments. A third type are intermediate agents facilitating developments as boundary spanners and policy entrepreneurs, without pursuing urban development themselves but aiming at realizing broader policy goals. Our general typology provides a rich picture of actors involved in bottom-up urban developments by applying theories from domains of innovation management and business transition management to urban planning and development studies. It shows that the social entrepreneurs in bottom-up urban development can be considered the result of social innovation, but this social innovation is set within a neoliberal context, and in many cases passively or actively conditioned by states and markets.

from the article: Abstract Based on a review of recent literature, this paper addresses the question of how urban planners can steer urban environmental quality, given the fact that it is multidimensional in character, is assessed largely in subjective terms and varies across time. The paper explores three questions that are at the core of planning and designing cities: ‘quality of what?’, ‘quality for whom?’ and ‘quality at what time?’ and illustrates the dilemmas that urban planners face in answering these questions. The three questions provide a novel framework that offers urban planners perspectives for action in finding their way out of the dilemmas identified. Rather than further detailing the exact nature of urban quality, these perspectives call for an approach to urban planning that is integrated, participative and adaptive. ; ; sustainable urban development; trade-offs; quality dimensions

Habitat fragmentation caused by urbanization and climate change are important drivers of biodiversity decline and ecosystem degradation (McKinney, 2002). Governmental inaction results in cascade effects, such as the extinction of species and the weakening of ecosystem services that citizens depend on. Alarming studies show the continuing loss of nature within European cities as they densify further to meet the demand for housing (Balikçi et al., 2022). The housing market is currently impacted negatively by economic factors and municipalities often respond by scaling back their sustainability ambitions. To avoid cosmetic greening of cities, the eco-social value of urban developments and their contribution to climate-change adaptation need to be made measurable. Developing nature-based urban areas offers opportunities to increase socio-ecological resilience (McPhearson et al., 2015; Spanjar et al., 2022).
In the two-year Nature-Based Area Development study researchers at four Dutch universities collaborated with planning professionals in cities, regions and companies to investigate how nature-based urban development can become a forceful reality. The study applied a combination of methods such as co-research sessions with consortium partners, in-depth interviews with experts and a multiple case study analysis of best practices in the Netherlands and abroad. Malmö and Stockholm are frontrunners in applying innovative green planning instruments such as Green Area Factor to meet high environmental ambitions (Kruuse, 2011). These instruments were also analysed and compared with eco-city projects in the Netherlands to identify their effectiveness in fostering nature and ecosystem services.
The analysis shows barriers in governance and spatiality between public and (semi-)private developments. Policy silos and ownership divisions often lead to standalone interventions that negatively impact social and ecological connectedness and projects’ potential for climate-change adaptation. Nature-based urban developments require a proactive effort to understand the precise ecological demands across scales and how they can be harnessed effectively in these complex planning processes. The results of the study provide key lessons and inspiration to enable authorities to implement more effective nature-based planning instruments.
