Background: Over the last decades, many forest simulators have been developed for the forests of individual European countries. The underlying growth models are usually based on national datasets of varying size, obtained from National Forest Inventories or from long-term research plots. Many of these models include country- and location-specific predictors, such as site quality indices that may aggregate climate, soil properties and topography effects. Consequently, it is not sensible to compare such models among countries, and it is often impossible to apply models outside the region or country they were developed for. However, there is a clear need for more generically applicable but still locally accurate and climate sensitive simulators at the European scale, which requires the development of models that are applicable across the European continent. The purpose of this study is to develop tree diameter increment models that are applicable at the European scale, but still locally accurate. We compiled and used a dataset of diameter increment observations of over 2.3 million trees from 10 National Forest Inventories in Europe and a set of 99 potential explanatory variables covering forest structure, weather, climate, soil and nutrient deposition. Results: Diameter increment models are presented for 20 species/species groups. Selection of explanatory variables was done using a combination of forward and backward selection methods. The explained variance ranged from 10% to 53% depending on the species. Variables related to forest structure (basal area of the stand and relative size of the tree) contributed most to the explained variance, but environmental variables were important to account for spatial patterns. The type of environmental variables included differed greatly among species. Conclusions: The presented diameter increment models are the first of their kind that are applicable at the European scale. This is an important step towards the development of a new generation of forest development simulators that can be applied at the European scale, but that are sensitive to variations in growing conditions and applicable to a wider range of management systems than before. This allows European scale but detailed analyses concerning topics like CO2 sequestration, wood mobilisation, long term impact of management, etc.

The fast development of laboratory methods has revealed increased amounts of trace concentrations of pharmaceuticals and personal care products (PPCP) in waste waters in the Czech Republic. This paper focuses on the expected costs to solve this problem by quaternary treatment of waste water based on activated carbon filtration. The one-time investment costs in 155 wastewater treatment plants (WWTPs) with a capacity of over 10 000 population equivalent (PE) would represent an amount of around 300 million EUR. The increase in end-user operat-ing costs would be 0.4 EUR/m3, which would mean a 15% increase in water and sewage costs. A sociological survey showed that most respondents (65%) would agree with an increase in price but only by 10%. Currently the cost of the qua-ternary treatment of wastewater is based primarily on estimates. Therefore changes in legislation leading to stricter limits and an increase in the efficiency of wastewater treatment should be preceded by additional applied research.

The COST RELY Glossary on Renewable Energy and Landscape Quality is the result of the European COST RELY project that focused on investigating the influence of renewable energy production on landscape quality. 31 people participated in developing and revising the definitions and descriptions for the 46 terms included in the glossary. Work was done in the period from 2015 to 2017 in multiple rounds of revision done by the RELY experts. Terms in the glossary are clustered into three groups: first group terms are directly connected to the landscape and its characteristics, the second one touches the planning process and methods, and the last one covers different renewable energy sources and production types. Each entry to the glossary consists of six elements: the term, definition, related terms, keywords, illustration(s) and sources. The terms are based on the expert knowledge of the contributors, scientific literature (monographs and articles), EU regulation, relevant web pages and other useful sources, stated in the Reference section. At the end of the glossary, terms are translated into 28 European languages including Esperanto. The glossary targets the researchers from the field, policy makers, local communities, investors in the sector of renewable energy and NGOs concerned with the matter in order to assure that people from different educational background and profession understand and use the term in the same manner. Beside from internal Action use, the terms shall contribute to existing glossaries on the relevant topics.

Abstract
Numerous species of wild berries are abundant in the Nordic forests, mountains and peat lands. They ripen throughout the early summer until late autumn. Both lingonberry (Vaccinium vitis-idaea) and bilberry (Vaccinium myrtillus), that are among the most picked wild berries, are characteristic field layer species in boreal forests. Other species that have potential of being better exploited are cloudberry (Rubus chamaemorus), crowberry (Empeterum nigrum), bog blueberry (Vaccinium uliginosum), arctic bramble (Rubus arcticus), wild strawberries/woodland strawberries (Fragaria vesca) and wild raspberries (Rubus idaeus). Wild berries have always been an important part of the Nordic cuisine. However, only about 5–10 per cent of the annual wild berry crop of approximately a billion kilograms are currently picked for private or commercial consumption. There are several challenges towards an increased utilization as year-to-year variation in crop, topography, logistics of berry picking including traceability, fragmented sector structure and the high share of unprocessed raw material in export. The scientific interest for these berries have in the recent years focused on their value concerning human health benefits. Nevertheless, commercialization and innovation of wild berries should focus on multiple use of the whole raw material into many different products. The Nordic wild berries are perfectly adapted to their environment and are well suited to studies of environmental effects on growth, development and quality. Additionally, they represent a valuable genepool for future breeding.
