There has probably never been such an intense debate about the layout of the countryside as the one that is currently raging. There are serious concerns about the landscape, which is being rapidly transformed by urbanization and everything associated with this process, and not only in the Netherlands but also far beyond its borders. Everyone has something to say in this society-wide debate, from local to national governments, from environmental factions to the road-user's lobby, and from those who are professionally involved to concerned private parties. In many cases it is a battle between idealized images and economic models, between agricultural reality and urban park landscapes, between ecological concerns and mobility. This issue of OASE explores the potential significance of architectonic design for transformation processes on the regional scale. Besides considering the instruments that are available to the designer to fulfil this task, the authors also consider how the design can exercise a 'positive' influence on such processes. The various contributions shed light on the potential significance of territory in contemporary design practice and offer critical reflection on the topical discourse that has evolved over recent years.

Marine spatial planning (MSP) was developed as a place-based, integrated marine governance approach to address sectoral and fragmented management issues and has seen significant evolvement over the past two decades. MSP has rapidly become the most commonly endorsed management regime for sustainable development in the marine environment, with initiatives being implemented across multiple regions of the globe. Despite its broad and growing acceptance and use, there are several key challenges that remain, both conceptual and practical, that are negatively impacting the realization of MSP’s potential. These include institutional shortcomings, the exclusion of stakeholders, a failure to account for the human and social dimensions of marine regions, the marginalization of different types of knowledge, and the growing need to adapt to global environmental change. Although studies have examined the emergence of MSP in different geographical and institutional contexts, there is a lack of comparative analysis of how initiatives are progressing and if the foundational aims of MSP are being achieved. There is a need to analyze the degree to which MSP initiatives are responding to the environmental challenges that they have been set up to tackle and, as marine plans are setting out long-term visions for marine management, to understand if current initiatives are fit for purpose. This article responds to these concerns and reviews the evolution of MSP within 12 regional ocean areas. We utilize the term regional ocean areas to illustrate the geographical spread of MSP, with examinations conducted of the approach to MSP that specific nations within each of the 12 chosen clusters have followed. By critically assessing how MSP is progressing, it is possible to shed light on the opportunities and challenges that are facing current initiatives. This can help to reveal learning lessons that can inform future MSP systems and guide initiatives along more sustainable pathways.

Background and purpose: Automatic approaches are widely implemented to automate dose optimization in radiotherapy treatment planning. This study systematically investigates how to configure automatic planning in order to create the best possible plans. Materials and methods: Automatic plans were generated using protocol based automatic iterative optimization. Starting from a simple automation protocol which consisted of the constraints for targets and organs at risk (OAR), the performance of the automatic approach was evaluated in terms of target coverage, OAR sparing, conformity, beam complexity, and plan quality. More complex protocols were systematically explored to improve the quality of the automatic plans. The protocols could be improved by adding a dose goal on the outer 2 mm of the PTV, by setting goals on strategically chosen subparts of OARs, by adding goals for conformity, and by limiting the leaf motion. For prostate plans, development of an automated post-optimization procedure was required to achieve precise control over the dose distribution. Automatic and manually optimized plans were compared for 20 head and neck (H&N), 20 prostate, and 20 rectum cancer patients. Results: Based on simple automation protocols, the automatic optimizer was not always able to generate adequate treatment plans. For the improved final configurations for the three sites, the dose was lower in automatic plans compared to the manual plans in 12 out of 13 considered OARs. In blind tests, the automatic plans were preferred in 80% of cases. Conclusions: With adequate, advanced, protocols the automatic planning approach is able to create high-quality treatment plans.

The Maritime Spatial Planning (MSP) Challenge simulation platform helps planners and stakeholders understand and manage the complexity of MSP. In the interactive simulation, different data layers covering an entire sea region can be viewed to make an assessment of the current status. Users can create scenarios for future uses of the marine space over a period of several decades. Changes in energy infrastructure, shipping, and the marine environment are then simulated, and the effects are visualized using indicators and heat maps. The platform is built with advanced game technology and uses aspects of role-play to create interactive sessions; it can thus be referred to as serious gaming. To calculate and visualize the effects of planning decisions on the marine ecology, we integrated the Ecopath with Ecosim (EwE) food web modeling approach into the platform. We demonstrate how EwE was connected to MSP, considering the range of constraints imposed by running scientific software in interactive serious gaming sessions while still providing cascading ecological feedback in response to planning actions. We explored the connection by adapting two published ecological models for use in MSP sessions. We conclude with lessons learned and identify future developments of the simulation platform.

Swarm planning is a theory and practical approach to deal with uncertain futures. By anticipating scenarios such as a ‘post-carbon’ world and a ‘pre-adaptive’ landscape, it offers an alternative pathway to prepare for medium-term incremental and step changes. The focus is on the regional scale with a planning process to move from an unstable state (i.e. due to external impacts of climate change) towards a state of higher adaptive capacity. It increases the flexibility of spatial systems in two ways: assisting change in spatial land use over time; and catalysing the emergence of autonomous and more resilient developments. Swarm planning theory is used in two pilot designs and compared with regular planning processes. The results are presented in the form of new landscapes: the ‘Zero-Fossil Region’, where the design provides a spatial framework for a complete renewable energy supply, and the ‘Net Carbon Capture Landscape’, in which adaptation and mitigation strategies are designed to become carbon positive. The comparison illuminates the potential advantage of swarm planning to tackle climate change threats. La planification en essaims est une théorie et une approche pratique visant à traiter des avenirs incertains. Au moyen de scénarios prospectifs tels que celui d'un monde « post-carbone » et d'un paysage « préadaptatif », elle offre une voie alternative pour se préparer à des changements progressifs ou radicaux à moyen terme. L'accent est mis sur l’échelle régionale, avec un processus de planification permettant de passer d'un état instable (c'est-à-dire dû aux incidences extérieures du changement climatique) à un état présentant une plus grande capacité adaptative. Cela accroît de deux manières la flexibilité des systèmes spatiaux : en favorisant le changement dans l'utilisation spatiale des terrains au fil du temps; et en catalysant l’émergence de développements autonomes et plus résilients. La théorie de la planification en essaims est utilisée dans deux conceptions pilotes et comparée aux processus de planification habituels. Les résultats sont présentés sous la forme de nouveaux paysages : la « Région Zéro Energie Fossile », dans laquelle la conception fournit un cadre spatial permettant un approvisionnement énergétique entièrement renouvelable, et le « Paysage à Séquestration Nette de Carbone », dans lequel des stratégies d'adaptation et d'atténuation sont conçues pour assurer un bilan carbone positif. Cette comparaison se révèle éclairante quant à l'avantage potentiel de la planification en essaims pour s'attaquer aux menaces posées par le changement climatique.

This book discusses the way that a nature-driven approach to urbanism can be applied at each of the urban scales; architectural design, urban design of neighborhoods, city planning and landscape architecture, and at the city and regional scales. At all levels nature-driven approaches to design and planning add to the quality of the built structure and furthermore to the quality of life experienced by people living in these environments. To include nature and greening to built structures is a good starting point and can add much value. The chapter authors have fiducia in giving nature a fundamental role as an integrated network in city design, or to make nature the entrance point of the design process, and base the design on the needs and qualities of nature itself. The highest existence of nature is a permanent ecosystem which endures stressors and circumstances for a prolonged period. In an urban context this is not always possible and temporality is an interesting concept explored when nature is not a permanent feature. The ecological contribution to the environment, and indirect dispersion of species, from a temporary location will, overall add biodiversity to the entire system.
