In this publication, the four authors provide several solution directions to shape that transition to a new, sustainable agricultural system. With a different relationship between food production and nature and the environment. It is the - necessary - basis for a good agricultural agreement. And the way to work towards a sustainable future for our agricultural sector and food system.

This paper introduces the Smart City Hospitality Framework, which could serve as the foundation for a destination-design-driven approach to urban tourism governance and dealing with overtourism issues. This conceptual framework is purposely designed to stimulate collaborative (informed) reflections on overtourism and urban tourism development that could support system analyses, problem structuring and development of transition agendas and pathways within the context of turning urban tourism into a transition arena that contributes to setting in motion a sustainability transition at city level. It merges the dimensions of sustainable development (environmentally responsible and equitable economic development) and city hospitality (the extent to which the city acts as a good ‘host’ to all its ‘guests’, including residents and businesses). Resilience resides at its centre to highlight the temporal aspects of these dimensions, and their interdependencies. To show how this framework can serve as the foundation for destination design efforts in practice, a short description of (experiences with) serious game-playing sessions that employ its logic in six European cities is provided.

From an interspecies perspective, we advocate for a theoretical foundation aimed at facilitating further research towards digitally mediated human-animal interaction. The proposed framework follows an approach we call 'digitally complemented zoomorphism' and recognizes 'play' as a free and voluntary activity that is shared by both animals and humans. As a result, three initial design guidelines will emerge. Our work is pursued in order to provide animals with stimulations which stem from a closer understanding of their perceptions and are not solely designed around human subjectivity.

Worldwide, coral reefs are rapidly declining due to increased sea water temperatures and other environmental stresses (Figure 1). To counter the extinction of major coral reef building species on the island of Bonaire, the non-profit organization Reef Renewal Foundation Bonaire is restoring degraded reef sites using corals that are grown in local nurseries. In these nurseries, corals are propagated on artificial trees using fragmentation. After 6-8 months of growth in the nursery, the corals are transplanted to degraded reef sites around the island. Over the years more than 21.000 corals have been outplanted to reef restoration sites in this way. These corals show high survivorship under natural reef conditions but remain under threat by environmental disturbances, such as increased water temperatures, diseases, and competition with macroalgae. A promising intervention to increase reef persistence and resilience is to manipulate the coral-associated microbiome. At present, the composition of the microbiome in nursery-reared and outplanted corals on Bonaire is unknown. The aim of the current project is to identify and isolate naturally occurring beneficial bacteria that may stimulate the resilience of these corals. Our key objectives are: 1) to assess the presence of functionally beneficial bacteria in corals in nursery and restoration sites on Bonaire using metagenomic screening. 2) to design culture strategies to isolate these functionally beneficial bacteria. In the future, a selection of these beneficial bacteria can be applied to the corals to increase their resilience against environmental disturbances.
De koraalriffen van de Caribisch Nederlandse eilanden St. Eustatius en Saba zijn van groot ecologisch en economisch belang. Door een opeenstapeling van bedreigingen is de hoeveelheid driedimensionale structuur op het rif afgenomen en zijn herbivore sleutelsoorten verdwenen. Het rif wordt overwoekerd met algen, die nieuwe koraalaanwas bemoeilijken. Lokale natuurbeheerorganisaties STENAPA en SCF willen artificiële riffen inzetten, om het ecosysteem door middel van “Building with Nature” te herstellen. Artificiële riffen worden wereldwijd in toenemende mate gebruikt, maar de doeltreffendheid hangt in sterke mate af van hoe er rekening is gehouden met de lokale omstandigheden en doelstellingen. Als de riffen goed functioneren kunnen sleutelsoorten herstellen en kan koraal zich weer vestigen. De natuurbeheerorganisaties willen weten hoe artificiële riffen optimaal bij kunnen dragen aan het herstel van het koraalrif ecosysteem bij St. Eustatius en op de Saba bank. Van Hall Larenstein, STENAPA, SCF, IMARES, CNSI en Golden Rock Dive Centre werken samen in het AROSSTA (Artificial Reefs on Saba and Statia) project om deze vraag te beantwoorden. Hiervoor worden verschillende soorten artificiële riffen gebouwd van lokaal natuursteen en van veelgebruikte “reef balls”. De functionaliteit van de verschillende soorten artificiële riffen wordt bepaald door gedurende 1,5 jaar de vestiging van zee-egels, vissen en koraal te onderzoeken. Na afloop van dit project zal duidelijk zijn welk type artificieel rif het meest geschikt is voor beide onderzoeklocaties. Daarnaast is bekend wat het effect is van het gebruikte materiaal en het aanbrengen van extra schuilplaatsen op de functie van artificiële riffen. Tenslotte wordt inzicht gegeven in hoeverre artificiële riffen een bijdrage leveren aan het herstel van aangrenzende gebieden. Omdat het onderzoek uitgevoerd wordt op twee locaties, met contrasterende omstandigheden, zullen de resultaten van regionaal belang zijn om bestaande en toekomstige artificiële riffen optimaal te laten functioneren.
The maximum capacity of the road infrastructure is being reached due to the number of vehicles that are being introduced on Dutch roads each day. One of the plausible solutions to tackle congestion could be efficient and effective use of road infrastructure using modern technologies such as cooperative mobility. Cooperative mobility relies majorly on big data that is generated potentially by millions of vehicles that are travelling on the road. But how can this data be generated? Modern vehicles already contain a host of sensors that are required for its operation. This data is typically circulated within an automobile via the CAN bus and can in-principle be shared with the outside world considering the privacy aspects of data sharing. The main problem is, however, the difficulty in interpreting this data. This is mainly because the configuration of this data varies between manufacturers and vehicle models and have not been standardized by the manufacturers. Signals from the CAN bus could be manually reverse engineered, but this process is extremely labour-intensive and time-consuming. In this project we investigate if an intelligent tool or specific test procedures could be developed to extract CAN messages and their composition efficiently irrespective of vehicle brand and type. This would lay the foundations that are required to generate big data-sets from in-vehicle data efficiently.
