The crowd increasingly plays a key role in facilitating innovations in a variety of sectors, spurred on by IT-developments and the concomitant increase in connectivity. Initiatives in this direction, captured under the umbrella-term ‘crowd-based innovations’, offer novel opportunities in socio-technical systems by increasing the access, reach and speed of services. At the same time, they signify important challenges because these innovations occur in a context of traditional, well-established institutional and governance structures and practices. This dynamic is captured in the idea of the ‘institutional void’: the tension between traditional structures and (radically) new initiatives. Existing rules, standards and practices are challenged, which raises questions about the safeguarding of public values such as quality, legitimacy, efficiency and governance of crowd-based innovations. This article argues that understanding these tensions requires supplementing empirical research with an explicitly normative dimension to reach thorough and balanced conclusions to facilitate innovation while protecting the valuable elements in existing rules and regulations. Illustrated by a number of short examples, we propose a multidisciplinary research agenda towards formulating appropriate governance structures.

Scientific knowledge plays a pivotal yet problematic role in identifying, assessing and evaluating climate impacts, and hence in their governance. This raises questions of how knowledge for adaptation policy is made. This article studies the production of authoritative and meaningful knowledge claims in the Delta Committee, regional water management and urban warming. It is argued that the conventional supply-and-demand conceptualisation with its notion of ‘knowledge transfer’ has fundamental flaws. This study shows how the wicked issue of climate change is tamed and made tractable in climate adaptation. In these processes knowledge of climate change transforms. This article presents a conceptual apparatus to study transformation. Transformation has a Janus face. While transformation brings climate change in conversation with localised meaning to create concrete adaptation responses, it also closes down and becomes blind to particular climate risks. Transformations are affected by the goals and institutions of policy fields. To overcome problems of blindness and cognitive path dependencies, more institutional change is necessary than the current piggyback approach of mainstreaming and knowledge co-creation entails.

Cybersecurity is becoming increasingly vulnerable. DDos attacks, phishing e-mails, ransomware, Russian hacker attacks on the head office of a political party are all part of our daily online businesses, for governments too. Governments play various roles here. They are internet users and rely on information on the internet. They are also suppliers of online information and in these roles they are connected to citizens, companies and other governmental organisations. Because of the role they play in society, the government possesses huge quantities of – often sensitive – information. They have the legal and moral obligation to be careful with this information and to secure it properly. Providing adequate security for information, however, is not an easy task for governments, especially because they usually do not operate in isolation. What factors threaten the security of government information and the systems involved? And who is accountable for the security of the information chains that are becoming complex as a consequence of cooperation between organisations?
