Martien Visser neemt het Net-Zero scenario van het IEA onder de loep. “Het geeft een goede indruk van de uitdagingen die we voor ons hebben. Hoe gaan wie die waarmaken of zelfs overtreffen?”

This paper presents a report of some of the activities of the International Energy Agency's (IEA) Wind TCP Task 39. By identifying best practices in an international collaboration, Task 39 hopes to provide the scientific evidence to inform improved regulations and standards, increasing the effectiveness of quiet wind turbine technology. Task 39 is divided into five separate work packages, which address the broad wind turbine noise topic in successive steps; from wind turbine noise generation (WP2), to airborne noise propagation over large distances (WP3). The assessment of wind turbine noise and its impact on humans is addressed in WP4, while WP5 is dealing with other aspects of perception and acceptance, which may be related to noise. All WPs contribute to a dedicated Work Package on dissemination (WP1). This paper provides an update of activities primarily associated with the socio-psychological aspects of wind turbine noise (WP4 and WP5). Through the consideration of a wide variety of factors, including measurement technologies, auralisation and psychology, the effects on noise perception, annoyance and its impact on wellbeing and health is being further investigated. This paper presents a discussion of the activities of each member country and highlights some of the key research questions that need to be further considered.

To support the implementation of the Ecosystem Based approach to Management (EBM), ICES strives to provide evidence-based scientific advice and relevant management options that also assess potential trade-offs among sectors or between environmental status and human uses. To help achieve this, the Workshop on Challenges, Opportunities, Needs and Successes in including human dimensions in Integrated Ecosystem Assessments (IEAs) (WKCONSERVE) focused on economic, social, and interdisciplinary research and data needed to inform on the societal drivers and objectives of marine resource use as context for advice. More specifically, the workshop goals were to a) summarize social and economic data, indicators and relevant research done across ICES IEA regions and other IEA regions, b) Identify goals for including social and economic data and analyses in different IEAs, and c) to develop a roadmap for including social and economic data and analyses in IEAs, identifying common needs across groups and unique priorities of each region. Discussion across IEA groups made clear that while great strides have been made in ICES IEA groups to identify and provide important ecological measures relevant to EBM, far less attention has been given to providing comparable economic and social information. WKCONSERVE identified a number of practical steps to take to include more societal measures relevant to EBM. These differ among regions, depending on data availability and ecosystem context, and are detailed in IEA roadmaps developed during the workshop. However, in general, the first step involves including social scientists in the IEA groups. Key topics and data for each IEA region were identified. It was, however, repeatedly noted that more interaction with stakeholders will help both IEA and human dimensions Expert Groups to better develop research and data collection efforts to address stakeholder needs. A lack of funding is a key obstacle to the development of IEAs, both regarding science and advisory products. It is now up to each IEA group to use the developed roadmaps to include the human dimension in IEAs. Furthermore, to support the development of methods for integration, follow-up workshops should be organized on a regular basis (e.g. every other year).

With increasing activities of multiple sectors in marine spaces, management of marine social–ecological systems requires more holistic approaches. Adopting such an approach, however, presents difficult institutional and disciplinary challenges. Here, we use the International Council for the Exploration of the Sea (ICES) as a case study on the implementation of ecosystem-based management (EBM) and integrated ecosystem assessments (IEAs). ICES includes EBM and IEAs in its Science Priorities and established IEA Working Groups (WGs) to carry out regional IEAs. But to what degree does this IEA WG work follow best practices? We examine policy documents, academic literature, and interview data from chairs of all IEA WGs. Results indicate mixed success. All groups acknowledge the holistic goals of IEA, and many use the IEA model as laid out by Levin et al. However, we found a significant variation in the degree to which the full model is applied. We identified two primary areas for improvement: (1) integration of social and economic issues and (2) involvement of stakeholders. We offer examples of how WGs have been making progress towards full IEAs, discuss how ICES can further support this transition, and suggest lessons with respect to the adoption of EBM and IEAs more broadly.

In zijn inaugurele rede gaat Bert Plomp in op het belang van praktijkgericht onderzoek voor de verdere ontwikkeling en implementatie van zonnestroom en op het gebruik van zonnestroom voor schoon en stil vervoer en mobiliteit. Ook de ambities van het lectoraat en de hoofdlijnen en speerpunten van het onderzoek komen aan bod en de relaties met het onderwijs, het regionale bedrijfsleven en lopende projecten

Aardgas blijft nog lang de ruggengraat van onze energievoorziening, stelt Martien Visser. Het mondiale gasverbruik is het afgelopen decennium jaarlijks toegenomen.

Een aanzienlijk deel van het dakoppervlak van bedrijven in Nederland bestaat uit asbesthoudende materialen. Deze daken vormen een potentieel gevaar voor de volksgezondheid, vooral bij brand. In de provincie Overijssel gaat het om circa 1 miljoen vierkante meter dakoppervlak, waarvan circa 90.000 vierkante meter in de gemeente Rijssen-Holten. Deze daken zijn niet zelden in slechte staat van onderhoud. Meestal zijn deze daken volledig ongeïsoleerd. In navolging van een eerder initiatief inzake asbestsanering van LTO Noord bij agrarische bedrijven hebben drie bedrijven in de gemeente Rijssen-Holten (Bouwfund BV, Roosdom Tijhuis BV en Zuna advies BV) het initiatief genomen om te onderzoeken hoe en in welke mate de asbesthoudende daken van industriële bedrijven in deze gemeente vervangen kunnen worden door asbestvrije daken. Hierbij hebben zij zich ten doel gesteld ten minste een kwart (> 25.000 m2) van de asbestdaken te vervangen door duurzame daken - asbestvrij, geïsoleerd en bij voorkeur voorzien van zonnepanelen - onder het motto: asbest er af, zonnepanelen er op! Het voortschrijdend inzicht – resultaat van het leerproces - bij de initiatiefnemers, de pilotbedrijven, Saxion, de gemeente Rijssen-Holten en de provincie Overijssel is overigens zowel een middel om tot een optimaal ontwerp te komen als een projectdoel, gericht op de algemene toepasbaarheid van het concept: asbest er af, zonnepanelen er op! te toetsen.
