Using socio-scientific issues as a learning context is an effective approach to achieve an important goal in science education, which is to enhance scientific literacy. It involves strengthening skills such as argumentation while also improving an understanding of the Nature of Science and imparting content knowledge. The present study evaluates the impact of a web-based educational instrument consisting of a unique combination of features designed to promote students’ development of skills and knowledge as well as to address the challenges faced by teachers in teaching socio-scientific issues. Participants included 423 students in secondary education. Students in the experimental condition received a three-lesson intervention with the educational instrument, and students in the control condition followed their regular science lessons. Findings indicated that the instrument proves effective in fostering learning outcomes while teachers benefit from the shift of managing classroom discussion to individual guidance of students. Applying the educational instrument in the classroom demonstrates promise in improving student engagement and their comprehension of socio-scientific issues.
Nature-based strategies, such as wave attenuation by tidal marshes, are increasingly proposed as a complement to mitigate the risks of failure of engineered flood defense structures such as levees. However, recent analysis of historic coastal storms revealed smaller dike breach dimensions if there were natural, high tidal marshes in front of the dikes. Since tidal marshes naturally only experience weak flow velocities (~0-0.3 ms-1 during normal spring tides), we lack direct observations on the stability of tidal marsh sediments and vegetation under extreme flow velocities (order of several ms-1) as may occur when a dike behind a marsh breaches. As a first approximation, the stability of a tidal marsh sediment bed and winter-state vegetation under high flow velocities were tested in a flume. Marsh monoliths were excavated from Phragmites australis marshes in front of a dike along the Scheldt estuary (Dutch-Belgian border area) and installed in a 10 m long flume test section. Both sediment bed and vegetation responses were quantified over 6 experimental runs under high flow velocities up to 1.75 ms-1 and water depth up to 0.35 m for 2 hours. These tests showed that even after a cumulative 12 hours exposure to high flow velocities, erosion was limited to as little as a few millimeters. Manual removal of the aboveground vegetation did not enhance the erosion either. Present findings may be related to the strongly consolidated, clay- and silt-rich sediment and P. australis root system in this experiment. During the flow exposure, the P. australis stems were strongly bent by the water flow, but the majority of all shoots recovered rapidly when the flow had stopped. Although present results may not be blindly extrapolated to all other marsh types, they do provide a strong first indication that marshes can remain stable under high flow conditions, and confirm the potential of well-developed tidal marshes as a valuable extra natural barrier reducing flood discharges towards the hinterland, following a dike breach. These outcomes promote the consideration to implement tidal marshes as part of the overall flood defense and to rethink dike strengthening in the future.

Healthcare settings are increasingly adopting nature-based interventions (NBIs) to support users’ health and well-being, but these interventions are often underutilized. To get a grip on utilization problems, insight into factors that affect use and uptake of NBIs in routine care is needed. This scoping review aimed to provide an overview of factors that facilitate or impede successful implementation of NBIs in hospitals, long-term care facilities for the elderly (LTCF), and rehabilitation centers. Systematic searches were conducted across various databases to identify studies that collected qualitative and/or quantitative data on the implementation of NBIs in healthcare settings. Findings were classified into the five domains of the Consolidated Framework for Implementation Research. A total of 57 articles were included in the review. The articles provide detailed insight into facilitating and impeding implementation factors related to the intervention (e.g., awareness, adaptability, type of natural elements, accessibility, safety, weather conditions, comfort, privacy, supportive design factors, activities). Other found factors related to the inner setting (e.g., culture, implementation climate) and individuals (e.g., characteristics and opportunities of stakeholders). Factors related to the outer setting (e.g., financing) and implementation process (e.g., teaming, assessing needs, planning, engaging, doing, integration in care and therapy, reflection and evaluation, maintenance) also emerged, but to a lesser extent. This review identified a broad range of factors important for the successful implementation of NBIs, which can guide implementation of future NBIs. To complement these findings, future studies should consider conducting implementation studies

The Dutch main water systems face pressing environmental, economic and societal challenges due to climatic changes and increased human pressure. There is a growing awareness that nature-based solutions (NBS) provide cost-effective solutions that simultaneously provide environmental, social and economic benefits and help building resilience. In spite of being carefully designed and tested, many projects tend to fail along the way or never get implemented in the first place, wasting resources and undermining trust and confidence of practitioners in NBS. Why do so many projects lose momentum even after a proof of concept is delivered? Usually, failure can be attributed to a combination of eroding political will, societal opposition and economic uncertainties. While ecological and geological processes are often well understood, there is almost no understanding around societal and economic processes related to NBS. Therefore, there is an urgent need to carefully evaluate the societal, economic, and ecological impacts and to identify design principles fostering societal support and economic viability of NBS. We address these critical knowledge gaps in this research proposal, using the largest river restoration project of the Netherlands, the Border Meuse (Grensmaas), as a Living Lab. With a transdisciplinary consortium, stakeholders have a key role a recipient and provider of information, where the broader public is involved through citizen science. Our research is scientifically innovative by using mixed methods, combining novel qualitative methods (e.g. continuous participatory narrative inquiry) and quantitative methods (e.g. economic choice experiments to elicit tradeoffs and risk preferences, agent-based modeling). The ultimate aim is to create an integral learning environment (workbench) as a decision support tool for NBS. The workbench gathers data, prepares and verifies data sets, to help stakeholders (companies, government agencies, NGOs) to quantify impacts and visualize tradeoffs of decisions regarding NBS.
‘Bomentaal’ betreft de ruimtelijke samenhang tussen boomsoorten, beplantingstypen en boomstructuren, en hun specifieke locatie (stad, wijk of straat). Dit onderzoek naar de configuraties van boombeplanting in Delft is de eerste stap om een nieuwe methodiek te ontwikkelen om dit vocabulaire van boomstructuren in Nederlandse laaglandsteden te ontrafelen, als drager en handvat voor de herziening en uitbreiding van het urban forest in Nederland. Stadsbomen zijn de ruggengraat van de groene stedelijke ruimte en leveren een belangrijke bijdrage aan het omgaan met gevolgen van klimaatverandering zoals hittestress, wateroverlast, luchtkwaliteit en achteruitgang van biodiversiteit. Dit is niet los te zien van de baten voor de gezondheid, de leefbaarheid, en het versterken van de stedelijke identiteit. Dit vraagt om een evaluatie en uitbreiding van het urban forest. Omdat de uitbreiding van het urban forest plaats zal vinden in en om bestaande steden is kennis van de bomentaal van deze steden onontbeerlijk. Het onderzoeken van de bestaande bomentaal - het scheppen van een ordening en het benoemen en tonen van essentiële eigenschappen verschillende typen boomstructuren - is onontbeerlijk bij de herziening en uitbreiding ervan. Voor dit onderzoek is gekozen voor de stad Delft: een typische laaglandstad met een lange geschiedenis van stedelijke boombeplanting, en een grote transformatieopgave wat betreft uitbreiding en vernieuwing van de woningvoorraad, klimaatadaptatie, gezondheid en welzijn, leefbaarheid en het behoud van identiteit. Door de kleine schaal van Delft kan de ontsluiting van diens bomentaal derhalve als test-case dienen voor het ontwikkelen van methodes, inzichten en perspectieven voor het urban forest van het Nederlandse laagland. Het onderzoek analyseert de kenmerkende beplantingsstructuren in Delft op drie schaalniveaus (boom, boomarrangementen, groenstructuur) in diagrammatische tekeningen, beelden en tekst op basis van veldonderzoek, historische documentatie en cartografisch onderzoek. Zowel de fysiek-ruimtelijke, technische als sensorische aspecten van de bomentaal worden in kaart gebracht.
In the Netherlands, the theme of transitioning to circular food systems is high on the national agenda. The PBL Netherlands Environmental Assessment Agency has stressed that commuting to circular food chains requires a radical transformation of the food chain where (a) natural resources must be effectively used and managed (soil, water, biodiversity, minerals), (b) there must be an optimum use of food by reducing (food) waste . . ., (c) less environmental pressure, and (d) an optimum use of residue streams. The PBL also recognizes that there should be room for tailored solutions and that it is important to establish a benchmark, to be aware of impacts in the production chain and the added value of products. In the line of circular food systems, an integrated nature-inclusive circular farming approach is needed in order to develop a feasible resource-efficient and sustainable business models that brings shared value into the food chain while invigorating the rural areas including those where agricultural vacancy is occurring. Agroforestry is an example of an integrated nature-inclusive circular farming. It is a multifunctional system that diversifies and adapts the production while reducing the carbon footprint and minimizing the management efforts and input costs; where trees, crops and/or livestock open business opportunities in the food value chains as well as in the waste stream chains. To exploit the opportunities that agroforestry as an integrated resource-efficient farming system adds to the advancement towards (a) valuable circular short food chains, (b) nature-based entrepreneurship (nature-inclusive agriculture), and (c) and additionally, the re-use of abandoned agricultural spaces in the Overijssel province, this project mobilizes the private sector, provincial decision makers, financers and knowledge institutes into developing insights over the feasible implementation of agroforestry systems that can bring economic profit while enhancing and maintaining ecosystem services.
