Trends in summer sulphate in Europe

A trend analysis of the sulphate concentration in Europe in the summer half-year was performed. Data from various measuring networks were analysed, but only stations with quality assured sampling methods and a record of more than 10 years were included in the study. 1978 served as the reference year for the trend, because in that year most stations started operation. The relatively dense network in Belgium provided the most valuable data, as evidenced by the fact that two sites at a distance of only 10 km apart correlated better than 95% over a month. The two sites also show a correlation of better than 90% over a season with two other stations at distances of 45 and 95 km. The relative decrease in summer-sulphate at the four stations in Belgium, as analysed by linear regression, was 3.3% per year which corresponds to an absolute decrease of 0.42 μgm⁻³ per year. In the Netherlands the average yearly decrease in summer-sulphate at two stations was 3.5% (−0.34 μgm⁻³). In other countries stations were further apart or only a single site wits in use, which limits the representativeness of the data. In northwestern Germany, a region with several monitoring stations, a yearly averaged decrease of 3.0% occurred. The lower absolute decrease (0.25 μgm⁻³) per year compared to that in the two neighbouring countries reflects the lower summer-time sulphate concentrations. In the remainder of Germany the average decrease was 1.6%. In South-Scandinavia the yearly relative decrease at two sites was 2.6% (0.13 μgm⁻³ absolute). There was no significant trend in the U.K. Al the Polish station the levels increased, it decreased at the Hungarian and Austrian station and remained constant at the Czechoslovakian site. Reasons for omission of the data from France from the trend analysis are discussed.     

Identifying future scenarios and their implications for transport policy

Scenario analysis is a technique that is increasingly being used as a way of identifying future policy options and issues in the long-term. This paper discusses the role of scenario analysis in policy development in relation to future transport policy. It discusses three key stages in scenario analysis: the identification of policy targets; the development of images of the future; and the construction of policy packages.     

The division of Europe into regions with similar potential effectiveness and environmental consequences of pesticide application based on expert inclusive research

A division of Europe into regions with similar climate and soil conditions, assuming similar pesticide effectiveness and environmental effects of their application, was developed by a combination of statistical cluster analysis and expert involvement for identifying clustering variables and weighing their importance. The experts identified 15 variables representing climatic, soil and crop structure data and weighted them. In order to maximally simplify the administrative work with pesticide registration resulting from the division of Europe into zones, the additional criteria in the procedure were: the zoning follows existing administrative borders, country divisions by zone boundaries are limited, and situations where a zone consists of parts separated by another zone are avoided. The results of the analyses were compared with the applicable EPPO classification and visualized on maps. The highest similarity was observed in the southern Mediterranean zone, the layout of which differed by only a few regions. The Alpine part, having specific conditions, was not distinguished among the EPPO zones. Our study very clearly delineated the Central European part, having a climate with continental influence, which is distributed among other zones in the EPPO classification.     

A survey on occupational accidents’ reporting and registration systems in the European Union

This paper presents the results of a survey on the procedures for reporting occupational accidents in the EU countries. It focuses particularly on the reporting and registration systems, as well as on the main characteristics of National Databases being used for the production of official statistics. The survey shows that many European countries have different methods and procedures for collecting and compiling data on occupational accidents, which inevitably pose problems when comparing accident statistics between the EU member states.The paper includes a brief review of the main goals and achievements of the European Project ESAW (European Statistics on Accidents at Work), which was launched in 1990 by the Eurostat (European Statistics), for the harmonisation of occupational accidents’ statistics among the member states. It is believed that the new variables being introduced by the harmonised methodology will quickly affect the way in which managers and insurance companies carry out their current procedures in several EU member states.The International Labour Organisation (ILO) recommendations and the future trends are also analysed. In conclusion, the study identifies opportunities for further development and research in the reporting and registration systems of occupational accidents.     

Water protection against pollution

Science-policy integration is one of the many complex challenges that scientific and policy-making communities are facing. It involves knowledge sharing and exchanges among a wide range of disciplines and actors. In many instances, the lack of proper communication and of a coordination mechanism leads to research outputs not being used or simply known by policy-makers, and to policy research needs not being communicated to the scientific communities in a timely fashion. This paper discusses the integration of scientific and technological progress into the policy-making and implementation process, with emphasis on water policies. It highlights the need and complexity of developing a knowledge-based approach which would enable to lead to an operational science-policy interface linked to WISE (Water Information System for Europe), including the newly developed WISERTD webportal (). The views expressed in this paper are purely those of the author and do not in any circumstances reflect an official position of the European Commission.     

Fertility Intentions and Risk Management: Exploring the Fertility Decline in Eastern Europe During Transition

Between 1985 and 1995, fertility in Eastern Europe declined from 2.2 children per woman to merely 1.5 on region-average. Previous research has emphasized mainly the economic turmoil during transition or the influx of new ideas regarding fertility and family relations. This article suggests that applying a risk management perspective on fertility patterns may put additional light on the reasons behind the fertility decline in post-communist Europe. The complexity of modern social systems has made people increasingly dependent on the state for risk evaluation and risk management. The article formulates the hypothesis that transition itself disrupted the mental models that helped people to navigate among the risks associated to having and raising children. Left to their own devices, women in Eastern Europe became more inclined to postpone childbirth or discard this option altogether.     

Developing spatially stratified N(2)O emission factors for Europe

We investigate the possibility to replace the – so-called – Tier 1 IPCC approach to estimate soil N₂O emissions with stratified emissions factors that take into account both N-input and the spatial variability of the environmental conditions within the countries of the European Union, using the DNDC-Europe model. Spatial variability in model simulations is high and corresponds to the variability reported in literature for field data. Our results indicate that (a) much of the observed variability in N₂O fluxes reflects the response of soils to external conditions, (b) it is likely that national inventories tend to overestimate the uncertainties in their estimated direct N₂O emissions from arable soils; (c) on average over Europe, the fertilizer-induced emissions (FIE) coincide with the IPCC factors, but they display large spatial variations. Therefore, at scales of individual countries or smaller, a stratified approach considering fertilizer type, soil characteristics and climatic parameters is preferable.
