Urban greening is a major goal in policies for sustainable cities, and spatial planners are nowadays strongly interested in the benefits of greenspace for the well-being of urban residents. We present a novel, model-based approach to support the development of effective greening strategies. The approach is quantitative and spatially explicit and accounts for multiple health benefits as well as burdens. In our study, we applied this generic approach to the city of Maastricht (The Netherlands) and conducted an integrated, city-scale assessment of the health benefits and burdens of four urban greenspace designs. These included: 'No greenspace', 'Current greenspace', 'Green parking lots and squares', and 'Optimized greenspace locations'. For each greenspace design, indicator values were calculated for five determinants of health and well-being: heat stress, air pollution, perceived unsafety, unattractive views, and tick-bite risk. To assess the health contribution of urban greenspace in a given design, these indicator values were compared with the values in the 'No greenspace' design. The study produced clear, quantitative conclusions about the health benefits and burdens of the urban greenspace designs for the case of Maastricht but also generated novel, more general insights relevant to the planning of urban greenspace for health and well-being. These insights concern the importance of translating health policy objectives into specific target values or thresholds and the importance of 'smart' choices in greenspace type and location that can effectively reduce trade-offs between health benefits and burdens, as well as the insights that adding more greenery not always improves urban health and that urban greenspace alone cannot solve major air pollution problems. The priorities for future research, which will address the limitations of the presented approach, concern a further expansion of the range of health benefits and burdens covered by the model and the development of a common metric for the entire range of health benefits and burdens to optimize greenspace design and maximize its overall net health benefit.

The idea that noncrop habitat enhances pest control and represents a win-win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing 132 studies and 6,759 sites worldwide to model natural enemy and pest abundances, predation rates, and crop damage as a function of landscape composition. Our results showed that although landscape composition explained significant variation within studies, pest and enemy abundances, predation rates, crop damage, and yields each exhibited different responses across studies, sometimes increasing and sometimes decreasing in landscapes with more noncrop habitat but overall showing no consistent trend. Thus, models that used landscape-composition variables to predict pest-control dynamics demonstrated little potential to explain variation across studies, though prediction did improve when comparing studies with similar crop and landscape features. Overall, our work shows that surrounding noncrop habitat does not consistently improve pest management, meaning habitat conservation may bolster production in some systems and depress yields in others. Future efforts to develop tools that inform farmers when habitat conservation truly represents a win-win would benefit from increased understanding of how landscape effects are modulated by local farm management and the biology of pests and their enemies.

Purpose: The purpose of this paper is to assess the current and potential value of the European Virtual Seminar on Sustainable Development (EVS) as an opportunity for professional development in Education for Sustainable Development (ESD) for teaching staff at university level. Design/methodology/approach: The paper presents and reflects on the specific case of EVS, including its competence-based approach and educational staff roles. Particular attention is paid to the development of ESD competences of tutors through participation in EVS, based on the UNECE (2011) competence framework and supported by the results from a small-scale questionnaire. Three major aspects of EVS as a professional opportunity in ESD are elaborated: EVS as an on-the-job training opportunity, EVS as an international staff mobility opportunity and EVS as an active learning and innovation community. Findings: EVS is an effective opportunity for developing a range of ESD competences, especially for junior university staff. The contribution of EVS to professional development in ESD currently extends to a partnership of ten universities from across Europe, but given its features, the EVS approach has the potential to be adopted at a much larger scale. Possible limitations in scaling up are rigid rules for integration of new courses in curricula and the need to form new EVS-like partnerships. Practical implications: This case study of EVS shows that Web-based, internationally networked courses with a pedagogical approach and design focused on ESD have a large potential in providing effective opportunities for the development of teachers' ESD competences, but to realize this potential, active uptake of the approach by the existing networks for ESD in higher education is needed. Originality/value: The paper presents a promising option to address the observed lack of opportunities within university curricula to acquire and practice ESD competences for teaching staff.

In collaborative learning environments, students work together on assignments in virtual teams and depend on each other's contribution to achieve their learning objectives. The online learning environment, however, may not only facilitate but also hamper group communication, coordination, and collaboration. Group awareness widgets that visualize information about the different group members based on information collected from the individuals can foster awareness and reflection processes within the group. In this paper, we present a formative data study about the predictive power of several indicators of an awareness widget based on automatically logged user data from an online learning environment. In order to test whether the information visualized by the widget is in line with the study outcomes, we instantiated the widget indicators with data from four previous runs of the European Virtual Seminar on Sustainable Development (EVS). We analyzed whether the tutor gradings in these previous years correlated with the students' scores calculated for the widget indicators. Furthermore, we tested the predictive power of the widget indicators at various points in time with respect to the final grades of the students. The results of our analysis show that the grades and widget indicator scores are significantly and positively correlated, which provides a useful empirical basis for the development of guidelines for students and tutors on how to interpret the widget's visualizations in live runs.

Urban green space (UGS) has important impacts on human health, but an integrated participatory approach to UGS design for improved residents' health has been lacking to date. The aim of our study was to develop and evaluate such a novel approach to address this gap. The approach was developed following guiding principles from the literature and tested with groups of children and elderly as participants in two neighborhoods of Maastricht (The Netherlands) with a low score in economic and health indicators. The novel aspects of the approach are the inclusion of both positive and negative health effects, the combination of resident self-assessment and model-based assessment of the health effects of UGS designs, and the use of maps to visualize UGS designs and health effects. The participant-generated UGS designs resulted in a considerable (up to fourfold) self-assessed increase in the use of the UGSs for meeting, stress reduction, and leisure-based physical activity as compared to the current situation. The model-assessed positive and negative health effects of the participant-generated UGS designs were limited: heat stress slightly decreased (by 0.1 °C), active transport slightly increased (by 30 m per day), and the perceived unsafety slightly increased (8%). The effects on unattractive views, air pollution, tick bite risk, and traffic unsafety were negligible. The major strength of this approach is that it combines active participation of residents in UGS (re)design with assessment of the health effects of these UGS designs. While in other participatory approaches to UGS design, it often remains unclear whether the resulting designs represent an improvement in terms of health, our combination of computer model-based assessment and a participatory process produced clear outcomes regarding the health benefits and use of UGS designs. A major recommendation for improvement is to involve decision makers already in the initial steps of the approach. [ABSTRACT FROM AUTHOR]
