Description: Introduction   The Consolider-Ingenio 2010 project SCARCE, with the full title “Assessing and predicting effects on water quantity and quality in Iberian Rivers caused by global change” aims to examine and predict the relevance of global change on water availability, water quality, and ecosystem services in Mediterranean river basins of the Iberian Peninsula, as well as their socio-economic impacts. Starting in December 2009, it brought together a multidisciplinary team of 11 partner Spanish institutions, as well as the active involvement of water authorities, river basin managers, and other relevant agents as stakeholders. Methods   The study areas are the Llobregat, Ebro, Jucar, and Guadalquivir river basins. These basins have been included in previous studies and projects, the majority of whom considered some of the aspects included in SCARCE but individually. Historical data will be used as a starting point of the project but also to obtain longer time series. The main added value of SCARCE project is the inclusion of scientific disciplines ranging from hydrology, geomorphology, ecology, chemistry, and ecotoxicology, to engineering, modeling, and economy, in an unprecedented effort in the Mediterranean area. The project performs data mining, field, and lab research as well as modeling and upscaling of the findings to apply them to the entire river basin. Results   Scales ranging from the laboratory to river basins are addressed with the potential to help improve river basin management. The project emphasizes, thus, linking basic research and management practices in a single framework. In fact, one of the main objectives of SCARCE is to act as a bridge between the scientific and the management and to transform research results on management keys and tools for improving the River Basin Management Plans. Here, we outline the general structure of the project and the activities conducted within the ten Work Packages of SCARCE.

Description: This paper attempts to assess whether renewable energy self-sufficiency can be achieved in the crop production and processing sector in Tanzania and if this could be accomplished in an environmentally sustainable manner. In order to answer these questions the theoretical energy potential of process residues from commercially produced agricultural crops in Tanzania is evaluated. Furthermore, a set of sustainability indicators with focus on environmental criteria is applied to identify risks and opportunities of using these residues for energy generation. In particular, the positive and negative effects on the land-use-system (soil fertility, water use and quality, biodiversity, etc.) are evaluated. The results show that energy generation with certain agricultural process residues could not only improve and secure the energy supply but could also improve the sustainability of current land-use practices.

Description: Global trade is increasingly being challenged by observations of growing burden shifting, in particular of environmental problems. This paper presents the first worldwide calculations of shifted burden based on material flow indicators, in particular direct and indirect physical trade balances. This study covers the period between 1962 and 2005 and includes between 82 and 173 countries per year. The results show that indirect trade flow volumes have increased to around 41 billion tonnes in 2005. The traded resources with the highest share of associated indirect flows are iron, hard coal, copper, tin and increasingly palm oil. Regarding the burden balance between regions, Europe is the biggest shifter whereas Australia and Latin America are the largest takers of environmental burden due to resource extraction. To evaluate the findings from a global perspective, the results are analysed in terms of resource flow induced environmental pressure related to a country's land area in terms of total and per capita area. Resource endowment and population density seem to be more relevant in determining the physical trade balance, including indirect flows, than income level.

Description: 1.Geolocation by light allows for tracking animal movements, based on measurements of lightintensity over time by a data-logging device (‘geolocator’). Recent developments of ultra-lightdevices (〈2 g) broadened the range of target species and boosted the number of studies using geolocators. However, an inherent problem of geolocators is that any factor or process that changes thenatural light intensity pattern also affects the positions calculated from these light patterns.Although the most important factors have been identified, estimation of their effect on the accuracyand precision of positions estimated has been lacking but is very important for the analyses andinterpretation of geolocator data. 2.The ‘threshold method’ is mainly used to derive positions by defining sunrise and sunset timesfrom the light intensity pattern for each recorded day. This method requires calibration: a pre-defined sun elevation angle for estimating latitude by fitting the recorded day⁄night lengths to theo-retical values across latitudes. Therewith, almost constant shading can be corrected for by findingthe appropriate sun elevation angle. 3.Weather, topography and vegetation are the most important factors that influence lightintensities. We demonstrated their effect on the measurement of day⁄night length, time of solarmidnight⁄noon and the resulting position estimates using light measurements from stationarygeolocators at known places and from geolocators mounted on birds. Furthermore, we investi-gated the influence of different calibration methods on the accuracy of the latitudinal positions. 4.All three environmental factors can influence the light intensity pattern significantly. Weatherand an animal’s behaviour result in increased noise in positioning, whereas topography and vegeta-tion result in systematic shading and biased positions. Calibration can significantly shift the esti-mated latitudes and potentially increase the accuracy, but detailed knowledge about the particularconfounding factors and the behaviour of the studied animal is crucial for the choice of the mostappropriate calibration method.

Description:    This review focuses on biological profiles of contemporary acaricides, acaricide resistance, and other up-to-date issues related to acaricide use in management of plant-feeding mites. Over the last two decades a considerable number of synthetic acaricides emerged on the global market, most of which exert their effects acting on respiration targets. Among them, the most important are inhibitors of mitochondrial electron transport at complex I (METI-acaricides). Discovery of tetronic acid derivatives (spirodiclofen and spiromesifen) introduced a completely new mode of action: lipid synthesis inhibition. Acaricide resistance in spider mites has become a global phenomenon. The resistance is predominantly caused by a less sensitive target site (target site resistance) and enhanced detoxification (metabolic resistance). The major emphasis in current research on acaricide resistance mechanisms deals with elucidation of their molecular basis. Point mutations resulting in structural changes of target site and leading to its reduced sensitivity, have recently been associated with resistance in Tetranychus urticae Koch and other spider mites. The only sustainable, long-term perspective for acaricide use is their implementation in multitactic integrated pest management programs, in which acaricides are applied highly rationally and in interaction with other control tactics. Considering that the key recommendation for effective acaricide resistance management is reduction of the selection for resistance by alternations, sequences, rotations, and mixtures of compounds with different modes of action, the main challenge that acaricide use is facing is the need for new active substances with novel target sites. Besides implementation of advanced technologies for screening and design of new synthetic compounds, wider use of microbial and plant products with acaricidal activity could also contribute increased biochemical diversity of acaricides.
