In today’s technological world, human intertwinement with the rest of nature hasbeen severely diminished. In our digital culture, many people hardly have any direct experience of and sense of connection with “the real” of the natural world. The author assumes that when we want to find ways to mend this gap, arts-based environmental education (AEE) can play a meaningful role. In AEE, artmaking is regarded as itself a way of potentially gaining new understandings about our natural environment. As a reflective practitioner, the author facilitated three different AEE activities, at several times and at diverse locations. On basis of his observations, memories, written notes, audio-visual recordings and interviews with participants, teachers and informed outsiders, he interpreted the experiences both of participants and himself. To this end he employed interpretative phenomenological analysis paired with autoethnography.The artmaking activities researched here aimed to bring about a shift in focus. Participants were encouraged to approach natural phenomena not head-on, but in an indirect way. Moreover, the artmaking process aspired to heighten their awareness to the presence of their embodied self at a certain place. The research questions that the author poses in this study are: (1) What is distinctive in the process of the AEE activities that I facilitate?; (2) Which specific competencies can be identified for a facilitator of AEE activities?; and (3) Does participating in the AEE activities that I facilitate enhance the ability of participants to have a direct experience of feeling connected to the natural world?In this explorative study, the author identifies facilitated estrangement through participating in AEE as an important catalyst when aiming to evoke such instances of transformative learning. In undergoing such moments, participants grope their way in a new liminal space. Artmaking can create favorable conditions for this to happen through its defamiliarizing effect which takes participants away from merely acting according to habit (on “autopilot”). The open-ended structure of the artmaking activities contributed to the creation of a learning arena in which emergent properties could become manifest. Thus, participants could potentially experience a sense of wonder and begin to acquire new understandings – a form of knowing that the author calls “rudimentary cognition.” The research further suggests that a facilitator should be able to bear witness to and hold the space for whatever enfolds in this encounter with artistic process in AEE. He or she must walk the tightrope between control and non-interfering.The analysis of the impacts of the AEE activities that were facilitated leads the author to conclude that it is doubtful whether these in and of themselves caused participants to experience the natural environment in demonstrable new and deep ways. He asserts that most of their awareness was focused on the internal level of their own embodied presence; engagement with place, the location where the AEE activity was performed, seemed secondary. The findings show that AEE activities first and foremost help bring about the ignition and augmentation of the participants’ fascination and curiosity, centered in an increased awareness of their own body and its interactions with the natural world. The present study can be seen as a contribution to efforts of envisaging innovative forms of sustainable education that challenge the way we have distanced ourselves from the more-than-human world.

This report focuses on the feasibility of the power-to-ammonia concept. Power-to-ammonia uses produced excess renewable electricity to electrolyze water, and then to react the obtained hydrogen with nitrogen, which is obtained through air separation, to produce ammonia. This process may be used as a “balancing load” to consume excess electricity on the grid and maintain grid stability. The product, ammonia, plays the role of a chemical storage option for excess renewable energy. This excess energy in the form of ammonia can be stored for long periods of time using mature technologies and an existing global infrastructure, and can further be used either as a fuel or a chemical commodity. Ammonia has a higher energy density than hydrogen; it is easier to store and transport than hydrogen, and it is much easier to liquefy than methane, and offers an energy chain with low carbon emissions.The objective of this study is to analyze technical, institutional and economic aspects of power-to-ammonia and the usage of ammonia as a flexible energy carrier.

Op de Klimaatconferentie in Parijs van 2015 is het 4 per 1000 initiatief gelanceerd. Dit initiatief stimuleert het vastleggen van koolstof in de bodem om de klimaatverandering tegen te gaan en tegelijkertijd de kwaliteit van de bodem te verbeteren en daarmee de voedselzekerheid te vergroten. De uitvoering van dit initiatief in Nederland is vastgelegd in het Klimaatakkoord. Tijdens een symposium bij de Amsterdam Green Campus (AGC) in 2019 over ‘Aansluiting onderzoek en onderwijs op het klimaatakkoord’, is de kiem gelegd voor een samenwerking tussen de partners van het AGC en de Université Catholique de Louvain (UCLouvain) m.b.t. het meten en monitoren van koolstofvastlegging in de bodem aan de hand van satellietbeelden.In 2020 is een verkennend onderzoek gestart, gefinancierd door de provincies Flevoland en Noord-Holland, met cofinanciering vanuit de onderwijsinstellingen. Hiermee is een eerste stap gezet om te bepalen of/hoe deze innovatieve meetmethode met satellietbeelden geschikt kan worden gemaakt voor toepassing onder Nederlandse omstandigheden (grondsoorten en teelt). Het project heeft inzicht en leerpunten opgeleverd over zowel de methodische aanpak als de samenwerking tussen de kennisinstellingen onderling en met het bedrijfsleven. Het inhoudelijke resultaat bood diverse aangrijpingspunten om de meetmethode gericht mee te optimaliseren. Daarom is in 2021 een nieuwe meetronde uitgevoerd met een aangepaste werkwijze.

Renewing agricultural grasslands for improved yields and forage quality generally involves eliminating standing vegetation with herbicides, ploughing and reseeding. However, grassland renewal may negatively affect soil quality and related ecosystem services. On clay soil in the north of the Netherlands, we measured grass productivity and soil chemical parameters of ‘young’ (5–15 years since last grassland renewal) and ‘old’ (>20 years since last grassland renewal) permanent grasslands, located as pairs at 10 different dairy farms. We found no significant difference with old permanent grassland in herbage dry matter yield and fertilizer nitrogen (N) response, whereas herbage N yield was lower in young permanent grassland. Moreover, the young grassland soil contained less soil organic matter (SOM), soil organic carbon (C) and soil organic N compared to the old grassland soil. Grass productivity was positively correlated with SOM and related parameters such as soil organic C, soil organic N and potentially mineralizable N. We conclude that on clay soils with 70% desirable grasses (i.e., Lolium perenne and Phleum pratense) or more, the presumed yield benefit of grassland renewal is offset by a loss of soil quality (SOM and N-total). The current practice of renewing grassland after 10 years without considering the botanical composition, is counter-productive and not sustainable.

Permanent grassland soils can act as a sink for carbon and may therefore positively contribute to climate change mitigation and adaptation. We compared young (5–15 years since latest grassland renewal) with old (>20 years since latest grassland renewal) permanent grassland soils in terms of carbon stock, carbon sequestration, drought tolerance and flood resistance. The research was carried out on marine clay soil at 10 dairy farms with young and old permanent grassland. As hypothesized, the carbon stock was larger in old grassland (62 Mg C ha−1) topsoil (0–10 cm) than in young grassland topsoil (51 Mg C ha−1). The carbon sequestration rate was greater in young (on average 3.0 Mg C ha−1 year−1) compared with old grassland (1.6 Mg C ha−1 year−1) and determined by initial carbon stock. Regarding potential drought tolerance, we found larger soil moisture and soil organic matter (SOM) contents in old compared with young grassland topsoils. As hypothesized, the old grassland soils were more resistant to heavy rainfall as measured by water infiltration rate and macroporosity (at 20 cm depth) in comparison with the young grassland soils. In contrast to our hypothesis we did not find a difference in rooting between young and old permanent grassland, probably due to large variability in root biomass and root tip density. We conclude that old grasslands at dairy farms on clay soil can contribute more to the ecosystem services climate change mitigation and climate change adaptation than young grasslands. This study shows that under real farm conditions on a clay topsoil, carbon stock increases with grassland age and even after 30 years carbon saturation has not been reached. Further study is warranted to determine by how much extending grassland age can contribute to climate change mitigation and adaptation.

In order to gain a more mature share in the future energy supply, green gas supply chains face some interesting challenges. In this thesis green gas supply chains, based on codigestion of cow manure and maize, are considered. The produced biogas is upgraded to natural gas quality and injected into the existing distribution gas grid and thus replacing natural gas. Literature research showed that relatively much attention has been paid up to now to elements of such supply chains. Research into digestion technology, agricultural aspects of (energy) crops and logistics of biomass are examples of this. This knowledge is indispensable, but how this knowledge should be combined to help understand how future green gas systems may look like, remains a white spot in the current knowledge. This thesis is an effort to fill this gap. A practical but sound way of modeling green gassupply chains was developed, taking costs and sustainability criteria into account. The way such supply chains can deal with season dependent gas demand was also investigated. This research was further expanded into a geographical model to simulate several degrees of natural gas replacement by green gas. Finally, ways to optimize green gas supply chains in terms of energy efficiency and greenhouse gas reduction were explored.

This chapter describes the growing influence of point-of-care diagnostics (POCD) on the daily lives of citizens, their immediate families, and healthcare providers. With a view to the future, the most important contemporary developments in this field are discussed, such as noninvasive sensor technology in the diagnostic process, practical examples of point-of-care diagnostics (POCD), including the quantify-self movement and infrared technology. Cost-effectiveness, adoption of POCD, and the contribution of POCD innovations to self-management and health literacy are also discussed. Developments in which deep learning and artificial intelligence are used to make the diagnostic results more reliable are also conferred, such as the development of point-of-care Internet diagnostics. The discussion of professional advice dilemma’s in POCD, the patient’s appreciation of POCD, and ethical and philosophical considerations conclude this chapter.

Schepen in moeilijkheden op zee leveren vaak besluitvormingsproblemen op tussen de scheepseigenaar/kapitein en de kuststaat. Kuststaten en met name de lokale overheden willen een probleem schip graag zo ver mogelijk weg sturen van hun gebied terwijl de eigenaar/kapitein zijn schip graag zo snel mogelijk naar de kust, een beschutte locatie of haven wil brengen. Het onderzoek geeft onderbouwing voor de besluitvorming rond schepen in moeilijkheden, zowel voor de zeescheepvaart als de betrokken besluitvormers van oeverstaten. Het product van het project is: een, op uitgewerkte scenario’s per scheepstype en lading gebaseerde besluitvormingsprocedure voor zeeschepen in moeilijkheden
