Governance of urban collectives in Amsterdam

Across European cities local entrepreneurs are joining forces in new ways, forming collectives to stimulate business growth and innovation and to create a more attractive business environment. The value of such collectives is increasingly recognized by local governments and policy measures to stimulate these initiatives are being developed. Amsterdam hosts different collaborative initiatives, including 39 business improvement districts (BIDs).The Knowledge Mile is such a collective in which shopkeepers, other local SMEs, residents work together to collectively improve a large retail area. The city of Amsterdam is also a stakeholder. Government can fill an important role in enabling the creation of collective resource management in urban settings. However, if effective regulation is missing, citizens and governing bodies have to look for incentives to find new means of addressing governance. As such, the potential for collective management of urban commons may be greater than realized so far, as there is still a lack of knowledge in this area. In this paper, we aim to bridge this gap. By means of an embedded case study approach, we analyze the interaction between the stakeholders in their development of a green zone, the Knowledge Mile Park, in the Wibautstraat. In the coming years, roofs, facades and ground level will be changed through a collaboration of residents, entrepreneurs, researchers, civil servants and students in a metropolitan Living Lab. In this Living Lab, solutions for a healthy and social environment, climate resistance and biodiversity are jointly developed, tested and shown. In our study, we will analyze the role of the governing bodies in such initiatives, and make recommendations how collectives can become more mainstream with new kinds of institutions, without an undue burden on the community.

RESILIO Final report

In today’s city environments, extreme weather conditions are a fact oflife. Amsterdam, Mumbai, Nairobi or Sydney… climate change issuesneed to be tackled all around the world.In the last couple of decades, Amsterdam has dealt with largeramounts of rainwater, severe heat stress and a decreased biodiversity.In order to strengthen urban resilience to climate change, blue-green(BG) roofs are increasingly being introduced. BG roofs placean additional water layer underneath the green layer. The idea is thatthese roofs reduce runoff after rainfall by retaining precipitation andmitigate heat stress, caused by increased evapotranspiration (the sumof evaporation from the land surface and transpiration from plants)and a higher albedo effect (the ability of surfaces to reflect sunlight).

The climate is right up your street

This book of examples suggests a variety of options for easy and accessible climate-resilient retrofitting of residential areas. The case studies for a set of common streets in the Netherlands will match urban settings in other countries. The examples show that effective climate-resilient retrofitting is usually quite simple and does not necessarily incur higher costs than traditional approaches, particularly in flat areas. An examination of typical Dutch urban street designs shows how climate resilience can be incorporated under different conditions while keeping costs down with retrofitting. We have investigated the effects of four retrofitting variants and specified their cost and benefits, applying a typology of common residential street characteristics. We sincerely hope these case studies inspire you to get started in your own town, city and country, because the climate is right up your street.

Retrofitting of urban areas

Climate-proof retrofitting of urban areas for the same cost

Due to climate change the frequency of extreme precipitation increases. To reduce the risk of damage by flooding, municipalities will need to retrofit urban areas in a climate-resilient way. To justify this investment, they need insight in possibilities and costs of climate-resilient urban street designs. This chapter focused on how to retrofit characteristic (Dutch) typologies of urban residential areas. For ten cases alternative street layouts were designed with a determination of the life cycle costs and benefits. All designs are resilient to extreme rain events. The results show that most flat urban typologies can easily be retrofitted in a climate-resilient way without additional costs compared to the standard way of retrofitting. Climate proofing sloping areas are highly dependent on the situation downstream. When there is no space downstream to divert the water into waterways or parks, costs to provide storage easily rise above traditional levels for retrofitting. In addition to reducing flood risk, for each case one variant includes resilience to extreme heat events making use of green. The life cycle costs and benefits of the green variants showed that especially green designs in high-density urban areas result in a better value for money.
