Citizen science on speed? Realising the triple objective of scientific rigour,policy influence and deep citizen engagement in a large-scale citizen science project on ambient air quality in Antwerp

Citizen science projects are increasingly recognised as catalyst for triggering behaviour change and building social capital around environmental issues. However, overview studies observe recurrent challenges in many citizen science projects in terms of combining high levels of data quality with deep citizen engagement and policy influence. This paper reports on the findings of the CurieuzeNeuzen project (www.CurieuzeNeuzen.eu), a large-scale citizen science project on air quality in Antwerp, delivering results in the three areas described above. Through CurieuzeNeuzen, 2,000 citizens studied the air quality levels in and around Antwerp in 2016 and were intensively deliberating on possible causes and solutions. Surveys were conducted at the start and towards the end of the project, with participants stating that their participation resulted in changed views and behaviour towards air pollution, mobility solutions, and city planning. The findings were picked-up academically and contributed to policy debates on air quality at city and regional level.     

Analysis on the performance of a high efficiency administrative building in Spain

A building is an element that consumes great quantities of primary energy both during construction and operating life. Buildings are reported to consume 40% of total primary energy in Europe. Efficiency and saving policies in this sector should be priority to reduce the European energetic dependence on third countries as well as to diminish greenhouse emissions.

The present work is aimed at review the results obtained during the first operating year of a public building with high energetic qualification in Mérida (Spain), which develops novel techniques on efficiency, energy saving and integration of renewable energies applied to the building sector. The building was constructed according to the climatic characteristics of Mérida. Diverse techniques regarding passive solar collection and thermal isolation, window and roofing shadowing and natural lighting were accounted for.

The results showed that it is possible to air-condition public buildings in extreme weather regions by applying specific measures to minimize energy consumption with the use of renewable energy sources (solar energy and biomass). Based on the actual energetic results, the economic, energetic, and environmental feasibility of this kind of building is also analyzed.

Chemical properties of soils in relation to forest composition in moist temperate valley slopes of Garhwal Himalaya, India

The present study was undertaken in moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the chemical properties of soils in relation to the forest structure and composition. Twelve forest types according to the altitude, slope aspect, and species composition were selected for the study. Chemical properties of the soil, i.e., total nitrogen (N), available phosphorus (P), available potassium (K), organic carbon (C), soil organic matter (SOM), pH and C:N ratios were analyzed for three different depths viz., (i) ??Upper?? (0?C10?cm), (ii) ??Middle?? (11?C30?cm), and (iii) ??Lower?? (31?C60?cm) in all the selected forest types. Phytosociological and diversity parameters viz. total basal cover (Gha^?1), stem density (Nha^?1), tree species richness (SR), Simpson concentration of dominance and Shannon?CWiener diversity index ( $ \overline{\rm H} $ ) were also calculated for each forest type. Values of N, P, K, C, SOM, C:N ratio and pH ranged from 0.17 to 0.45?%, 2.73 to 20.17?ppm, 40.67 to 261.17?ppm, 2.29 to 4.31?%, 3.95 to 7.43?%, 8.12 to 14.49 and 5.47 to 6.67, respectively. N showed a positive relationship with C and K. P was positively correlated with C and negatively correlated with altitude. P was higher in the soil of lower horizons of all the forest types. K was found to be positively correlated with altitude, C and N. pH of all the forest types was slightly acidic. C was comparatively higher in mixed broad-leaved forest types. No relationship between altitude and C was observed, which may be due to different composition of forest types along the altitudinal gradient and their differential decomposition rates. C content decreased with the depth of the soil. C showed positive correlation with N, P, and K. N showed a positive correlation with Gha^?1. K showed a negative correlation with SR and $ \overline{\rm H} $ . P showed no relationship with the phytosociological parameters. This study also provides the comparisons between the results of chemical analysis of the present study with numerous other previous studies in the temperate Himalayan region of the Uttarakhand. The values of soil chemical properties of the present study in most of the forest types are on the higher end than the values previously recorded for the other similar forests of the region. The possible reason being luxuriant vegetation and undisturbed nature of these forest types, which is evident from higher values of diversity and other phytosociological parameters.     

Automated energy management in distributed electricity systems: An EEPOS approach

The increasing capacity of distributed electricity generation brings new challenges in maintaining a high security and quality of electricity supply. New techniques are required for grid support and power balance. The highest potential for these techniques is to be found on the part of the electricity distribution grid.

This article addresses this potential and presents the EEPOS project’s approach to the automated management of flexible electrical loads in neighborhoods. The management goals are (i) maximum utilization of distributed generation in the local grid, (ii) peak load shaving/congestion management, and (iii) reduction of electricity distribution losses. Contribution to the power balance is considered by applying two-tariff pricing for electricity.

The presented approach to energy management is tested in a hypothetical sensitivity analysis of a distribution feeder with 10 households and 10 photovoltaic (PV) plants with an average daily consumption of electricity of 4.54 kWh per household and a peak PV panel output of 0.38 kW per plant. Energy management shows efficient performance at relatively low capacities of flexible load. At a flexible load capacity of 2.5% (of the average daily electricity consumption), PV generation surplus is compensated by 34–100% depending on solar irradiance. Peak load is reduced by 30% on average. The article also presents the load shifting effect on electricity distribution losses and electricity costs for the grid user.     

Images of nature: collaboration at the intersection of nature, art and technology

This paper argues that interdisciplinary collaboration between the sciences, the arts/humanities and engineering will provide innovative responses to important changes in our natural environment. Specifically, it will introduce ??Images of Nature??, a case study on creative collaboration and a multi-level research project at Purdue University, headed by Prof. Shannon McMullen and Prof. Fabian Winkler. By bringing together scientists, engineers and artists, ??Images of Nature?? aims to convey the significance of new understandings of nature in images and tangible artifacts (e.g., data visualization, functional devices, generative and kinetic installations) for the public. It is our hope that this project will be the starting point for a flexible network connecting science, engineering and the arts on Purdue??s West Lafayette campus to enrich STEM education and provide a local model for STE(A)M (STEM disciplines plus Art), which emphasizes creativity and innovation; critical thinking and problem solving; flexibility and adaptability; cross-disciplinary communication and collaboration in the context of our changing natural environment.     

“互联网+”时代的环境风险评估探讨

环境风险评估是环境管理的前提和依据。目前比较成熟的方法分为项目"事先"环评和健康"事后"风险评估。以上两种风险评估方法由于多种原因制约,无法提供给环境管理部门实时在线的环境风险结果。实际上,环境风险评估方法在不断完善中,随着互联网、物联网、云计算、三网融合等IT与通信技术的迅猛发展,环境保护领域也迎来了大数据时代,风险评估也将逐渐步入"互联网+"时代。新型环境风险评估更具系统性,将以数字化的形式体现环境(E)—污染物(M)—人为因素(H)的风险耦合度。虽然数字化环境风险评估在相关风险因子和风险评估方法上仍处于起步阶段,但它是新形势下环境风险管理的一个全新方向,其应用将对环境管理领域产生巨大影响。本文将分析传统环境风险评估与"互联网+"时代的环境风险评估差异,探讨新型数字化环境风险评估需要的支撑硬件与平台,并对数字化环境风险评估的发展趋势与挑战做出展望。

Modelling built-up land take in Europe to 2020: an assessment of the Resource Efficiency Roadmap measure on land

Land taken by artificial surfaces has an impact on the quality of life and ecosystems. To reduce possible negative impacts of land take, the European Commission proposed setting a milestone objective for 2020 in terms of future rates of land take.

This paper describes a methodology to model the impacts of the 2020 land-take milestone proposed in the RERM in the European Union 27 MS. An integrated modelling framework was configured to assess the spatial impact of two land-take scenarios: a ‘Reference’ scenario, which is driven by demographic and economic trends, and a ‘Target 0’ scenario that follows the 2020 land-take milestone proposed in the RERM. We conclude that the implementation of the 2020 land-take milestone, by reducing future land take in Europe, will foster more efficient use of land (less land taken for the same activity levels) and minimise negative impacts on non-artificial land uses.     

A general framework for a collaborative water quality knowledge and information network

Increasing knowledge about the environment has brought about a better understanding of the complexity of the issues, and more information publicly available has resulted into a steady shift from centralized decision making to increasing levels of participatory processes. The management of that information, in turn, is becoming more complex. One of the ways to deal with the complexity is the development of tools that would allow all players, including managers, researchers, educators, stakeholders and the civil society, to be able to contribute to the information system, in any level they are inclined to do so. In this project, a search for the available technology for collaboration, methods of community filtering, and community-based review was performed and the possible implementation of these tools to create a general framework for a collaborative ??Water Quality Knowledge and Information Network?? was evaluated. The main goals of the network are to advance water quality education and knowledge; encourage distribution and access to data; provide networking opportunities; allow public perceptions and concerns to be collected; promote exchange of ideas; and, give general, open, and free access to information. A reference implementation was made available online and received positive feedback from the community, which also suggested some possible improvements.

On causes of illegal waste dumping in Slovakia

This paper examines the determinants of illegal waste dumping at the county level in Slovakia (in 77 of 79 counties), using a truncated regression model. It analyzes a unique data-set composed of illegal dumping data provided by the TrashOut platform and sociodemographic data from the national statistical authority.

This study shows that a higher level of expected overall waste production results in a higher rate of illegally dumped waste and a higher number of illegal dumping sites. More precisely, income has a positive impact on the rate of illegal waste dumping, poverty influences the rate of illegal dumping negatively and a higher level of education does not result in more responsible waste management. On the contrary, higher education has a positive influence on the rate of dumping. A negative relationship between costs of illegal waste disposal and dumping rate, as well as a positive relationship between costs of legal waste disposal and dumping rate has been revealed.     

Conceptual Design of a System for Selecting Appropriate Groundwater Models in Groundwater Protection Programs

/ An effective groundwater protection program requires understanding of water flow and contaminant transport processes in the subsurface. Although many mathematical models have been developed to simulate the processes, few actually are used in groundwater protection programs due to the difficulties in data collection, model selection, and model implementation. This study presents a conceptual design of a GIS-supported model selection system that evaluates available data and mathematical models to facilitate groundwater protection programs. Steady-state groundwater and contaminant transport models applied in isotropic aquifers are placed into four classes to simulate conservative or nonconservative contaminant transports in simple or complex geohydrological conditions. After analyzing specific study objectives, available data, and model requirements, the proposed system selects a class of models that can be used in simulation and recommends any need for additional data collection. This study initiates an effort to integrate GIS, mathematical models, and expert knowledge in one system to promote the application of appropriate groundwater models. The new technology of GIS and digital data-base management makes it possible to develop such a system in practice.KEY WORDS: Groundwater models; Geographic information systems     

Paradise lost already? A naturalist interpretation of the pelagic avian and marine mammal detection database of the IceAGE cruise off Iceland and Faroe Islands in fall 2011

We present naturalist sightings of seabirds and marine mammals made during a research cruise with the IceAGE project off Iceland and the Faroe Islands during September 2011. Our findings from the obtained pelagic database are in-line with many other, more in-depth studies, showing major declines for pelagic seabirds and likely sea mammals, thus revising the role that Iceland now plays for such species. Northern Fulmar (Fulmarus glacialis) was the most recorded species, followed by different gulls, Black-legged Kittiwake (Rissa tridactyla) and Northern Gannet (Morus bassanus). However, Atlantic Puffin (Fratercula arctica) and Common Murre (Uria aalge) were only seen very rarely, and no observations were made of Dovekie (Alle alle) or Thick-billed Murre (U. lomvia). These observations were surprising since Iceland is known, so far, to host globally relevant populations of these auk species. A surprising high number of thirteen species of passerines were also detected offshore, mostly Wheatear (Oenanthe oenanthe), Meadow Pipit (Anthus pratensis) and Reed Bunting (Emberiza schoeniclus). Only a few marine mammals (Balaenoptera and Megaptera sp.) were encountered. Our detections present underestimates but are discussed in relation to ongoing and recently reported but dramatic anthropogenic changes of Iceland and in the North Atlantic overall. These include the substantial decrease in bird populations, overfishing and subsequent trophic cascades, as well as climate change, Arctic shipping and more industrial development to come. In light of these dramatic ecological changes, we conclude with an urgent request for an improved effective conservation management for Iceland, the North Atlantic and its stakeholders for directly related global governance to handle problems proactively.     

An Empirical Evaluation of Private Landowner Participation in Voluntary Forest Conservation Programs

The use of voluntary programs targeting resource conservation on private land has become increasingly prevalent in environmental policy. Voluntary programs potentially offer significant benefits over regulatory and market-based approaches. This article examines the factors affecting landowner participation in voluntary forest conservation programs using a combination of parcel-level GIS and remotely sensed data and semi-structured interviews of landowners in Monroe County, Indiana. A logistic regression model is applied to determine the probability of participation based on landowner education, membership in other non-forest voluntary programs, dominant land use activity, parcel size, distance from urban center, land resource portfolios, and forest cover. Both land use activity and the spatial configuration of a landholder’s resource portfolio are found to be statistically significant with important implications for the design and implementation of voluntary programs.

Application of environmental risk assessment for strategic decision-making in coastal areas: case studies in China

Environmental risk assessment (ERA) is a powerful technical tool for analyzing potential and extreme adverse environmental impacts, and has found wide application in supporting decision-making processes over the last two decades. However, to date there has been no interrelated application of ERA to support the processes of strategic decision-making (SDM), especially in coastal areas.

In this paper, we attempt to verify the feasibility of the proposed integrated ERA–SDM approach and its methodology by applying it to two case studies (in Xiamen Bay and Luoyuan Bay) of the principal coastal functional zoning (PCFZ, a kind of SDM and similar to the coastal and marine spatial planning in western). The results show that the integrated ERA–SDM approach could integrate ERA into the entire SDM process, directly support the PCFZ, and avoid or mitigate dire environmental risk that can be introduced by SDM processes.

Reinventing marine spatial planning: a critical review of initiatives worldwide

ABSTRACT

Although marine spatial planning (MSP) is increasingly being applied worldwide, it appears to be based on an ambiguity that has arisen from its dichotomous role of ensuring both conservation and development. This elusive ideal hints at a possible discrepancy between theory and practice. This paper explores the hypothesis that beyond a performative narrative, MSP is actually better described as a variety of devices which fulfil other roles and converge in terms of planning type. To test this hypothesis, this paper analyses the content of past and present MSP initiatives from around the world. The findings show that these initiatives view MSP either as a strategic sectoral spatial planning tool or strategic planning tool, brought in to complement existing initiatives. Furthermore, these two approaches can actually be seen to converge in the type of planning used, through the role attributed to spatial aspects, and more specifically in the place given to zoning. There are two key implications of these findings: the need to open up theoretical debates more broadly to different disciplinary perspectives on MSP; and the need for crucial choices to be made to ensure that MSP does not become an illusion behind which other agendas lie.

Highlights

• Several scientific communities are working on MSP in parallel

• MSP does not in reality fulfil its theoretical objectives, but it fulfils other roles

• We make a critical review of 44 experiences of MSP from throughout the world

• Different forms of MSP generally make similar uses of zoning

• MSP is both illusory and necessary and must engage a critical turn
