Adaptive governance describes the purposeful collective actions to resist, adapt, or transform when faced with shocks. As governments are reluctant to intervene in informal settlements, community based organisations (CBOs) self-organize and take he lead. This study explores under what conditions CBOs in Mathare informal settlement, Nairobi initiate and sustain resilience activities during Covid-19. Study findings show that CBOs engage in multiple resilience activities, varying from maladaptive and unsustainable to adaptive, and transformative. Two conditions enable CBOs to initiate resilience activities: bonding within the community and coordination with other actors. To sustain these activities over 2.5 years of Covid-19, CBOs also require leadership, resources, organisational capacity, and network capacity. The same conditions appear to enable CBOs to engage in transformative activities. How-ever, CBOs cannot transform urban systems on their own. An additional condition, not met in Mathare, is that governments, NGOs, and donor agencies facilitate, support, and build community capacities.

The growing sophistication, frequency and severity of cyberattacks targeting all sectors highlight their inevitability and the impossibility of completely protecting the integrity of critical computer systems. In this context, cyber-resilience offers an attractive alternative to the existing cybersecurity paradigm. We define cyber-resilience as the capacity to withstand, recover from and adapt to the external shocks caused by cyber-risks. This article seeks to provide a broader organizational understanding of cyber-resilience and the tensions associated with its implementation. We apply Weick's (1995) sensemaking framework to examine four foundational tensions of cyber-resilience: a definitional tension, an environmental tension, an internal tension, and a regulatory tension. We then document how these tensions are embedded in cyber-resilience practices at the preparatory, response and adaptive stages. We rely on qualitative data from a sample of 58 cybersecurity professionals to uncover these tensions and how they reverberate across cyber-resilience practices.

Since the early work on defining and analyzing resilience in domains such as engineering, ecology and psychology, the concept has gained significant traction in many fields of research and practice. It has also become a very powerful justification for various policy goals in the water sector, evident in terms like flood resilience, river resilience, and water resilience. At the same time, a substantial body of literature has developed that questions the resilience concept's systems ontology, natural science roots and alleged conservatism, and criticizes resilience thinking for not addressing power issues. In this study, we review these critiques with the aim to develop a framework for power-sensitive resilience analysis. We build on the three faces of power to conceptualize the power to define resilience. We structure our discussion of the relevant literature into five questions that need to be reflected upon when applying the resilience concept to social–hydrological systems. These questions address: (a) resilience of what, (b) resilience at what scale, (c) resilience to what, (d) resilience for what purpose, and (e) resilience for whom; and the implications of the political choices involved in defining these parameters for resilience building or analysis. Explicitly considering these questions enables making political choices explicit in order to support negotiation or contestation on how resilience is defined and used.

In line with the ‘Natuur- en milieubeleidsplan Caribisch Nederland 2020-2030 (NMBP)’ the consortium intends with this research proposal to contribute to a prosperous society with a resilient population and healthy natural environment. The Caribbean Netherlands are dealing with a situation where imported vegetables and fruits are mostly imported and hardly affordable. This leads to consuming unhealthy food and high obesities rates as a consequence. A lack of good agricultural practices with regard to water-smart and nature inclusive agriculture, as well as limited coping capacities to deal with hazards and climate change, results in very limited local production and interest. Initiatives that focused only on agrotechnological solutions for food resilient futures turned out to be ineffective due to a lack of local ownership, which jeopardizes sustainability. Moreover, the ‘green’ and ‘blue’ domains are not seen as attractive career perspectives among youth, hampering a bright future for those domains. The aim of this research is to contribute to water-smart and nature inclusive food resilience embedded in a local participatory perspective in the Caribbean Netherlands. To address the above challenges, a living lab approach is adopted, where youth will be trained as (co)-facilitators (WP1) who will contribute to a participatory envisioning process and an articulation of food resilient futures (WP2). Finally, based on the envisioning process local stakeholders will select and implement experiments for food resilient futures followed by dissemination of results among key stakeholders as well as children and youth at the BES islands (WP3). This project strategy will lead to a network of a living lab where professionals and youth work together on food resilient futures. Training manuals and the results of experiments with regard to water and food system alternatives will be used actively to encourage youth to be involved in sustainable agriculture and consumption.
Over the past decade, the trend in both the public sector and industry has been to outsource ICT to the cloud. While cost savings are often used as a rationale for outsourcing, another argument that is frequently used is that the cloud improves security. The reasoning behind this is twofold. First, cloud service providers are typically thought to have skilled staff trained in good security practices. Second, cloud providers often have a vastly distributed, highly connected network infrastructure, making them more resilient in the face of outages and denial-of-service attacks. Yet many examples of cloud outages, often due to attacks, call into question whether outsourcing to the cloud does improve security. In this project our goal therefore is to answer two questions: 1) did the cloud make use more secure?and 2) can we provide specific security guidance to support cloud outsourcing strategies? We will approach these questions in a multi-disciplinary fashion from a technical angle and from a business and management perspective. On the technical side, the project will focus on providing comprehensive insight into the attack surface at the network level of cloud providers and their users. We will use a measurement-based approach, leveraging large scale datasets about the Internet, both our own data (e.g. OpenINTEL, a large- scale dataset of active DNS measurements) and datasets from our long-term collaborators, such as CAIDA in the US (BGPStream, Network Telescope) and Saarland University in Germany (AmpPot). We will use this data to study the network infrastructure outside and within cloud environments to structurally map vulnerabilities to attacks as well as to identify security anti-patterns, where the way cloud services are managed or used introduce a weak point that attackers can target. From a business point of view, we will investigate outsourcing strategies for both the cloud providers and their customers. For guaranteeing 100% availability, cloud service providers have to maintain additional capacity at all times. They also need to forecast capacity requirements continuously for financially profitable decisions. If the forecast is lower than the capacity needed, then the cloud is not able to deliver 100% availability in case of an attack. Conversely, if the forecast is substantially higher, the cloud service provider might not be able to make desired profits. We therefore propose to assess the risk profiles of cloud providers (how likely it is a cloud provider is under attack at a given time given the nature of its customers) using available attack data to improve the provider resilience to future attacks. From the costumer perspective, we will investigate how we can support cloud outsourcing by taking into consideration business and technical constraints. Decision to choose a cloud service provider is typically based on multiple criteria depending upon the company’s needs (security and operational). We will develop decision support systems that will help in mapping companies’ needs to cloud service providers’ offers.
My research investigates the concept of permacomputing, a blend of the words permaculture and computing, as a potential field of convergence of technology, arts, environmental research and activism, and as a subject of future school curricula in art and design. This concept originated in online subcultures, and is currently restricted to creative coding communities. I study in what way permacomputing principles may be used to redefine how art and design education is taught. More generally, I want to research the potential of permacomputing as a critical, sustainable, and practical alternative to the way digital technology is being taught in art education, where students mostly rely on tools and techniques geared towards maximising productivity and mass consumption. This situation is at odds with goals for sustainable production and consumption. I want to research to what degree the concept of permacomputing can be broadened and applied to critically revised, sustainable ways of making computing part of art and design education and professional practice. This research will be embedded in the design curriculum of Willem de Kooning Academy, focused on redefining the role of artists and designers to contribute to future modes of sustainable organisation and production. It is aligned with Rotterdam University of Applied Sciences sectorplan masters VH, in particular managing and directing sustainable transitions. This research builds upon twenty years of experience in the creative industries. It is an attempt to generalise, consolidate, and structure methods and practices for sustainable art and design production experimented with while I was course director of a master programme at WdKA. Throughout the research I will be exchanging with peers and confirmed interested parties, a.o.: Het Nieuwe Instituut (NL), RUAS Creating 010 kenniscentrum (NL), Bergen Centre for Electronic Arts (NO), Mikrolabs (NO), Varia (NL), Media Arts department at RHU (UK), Media Studies at UvA (NL).
