Irrigation in the Yanqi Basin, Sinkiang, China has led to water table rise and soil salination. A model is used to assess management options. These include more irrigation with groundwater, water saving irrigation techniques and others. The model relies on input data from remote sensing.The Yanqi Basin is located in the north-western Chinese province of Xinjiang.This agriculturally highly productive region is heavily irrigated with water drawn from the Kaidu River. The Kaidu River itself is mainly fed by snow and glacier melt from the Tian Mountain surrounding the basin. A very poor drainage system and an overexploitation of surface water have lead to a series of environmental problems: 1. Seepage water under irrigated fields has raised the groundwater table during the last years, causing strongly increased groundwater evaporation. The salt dissolved in the groundwater accumulates at the soil surface as the groundwater evaporates. This soil salinization leads to degradation of vegetation as well as to a loss of arable farmland. 2. The runoff from the Bostan Lake to the downstream Corridor is limited since large amount of water is used for irrigation in the Yanqi Basin. Nowadays, the runoff is maintained by pumping water from the lake to the river. The environmental and ecological system is facing a serious threat.In order to improve the situation in the Yanqi Basin, a jointly funded cooperation has been set up by the Institute of Environmental Engineering, Swiss Federal Institute of Technology (ETH) , China Institute of Geological and Environmental Monitoring (CIGEM) and Xinjiang Agricultural University. The situation could in principle be improved by using groundwater for irrigation, thus lowering the groundwater table and saving unproductive evaporation. However, this is associated with higher cost as groundwater has to be pumped. The major decision variable to steer the system into a desirable state is thus the ratio of irrigation water pumped from the aquifer and irrigation water drawn from the river. The basis to evaluate the ideal ratio between river and groundwater - applied to irrigation - will be a groundwater model combined with models describing the processes of the unsaturated zone. The project will focus on the following aspects of research: (...)

The purpose of SuperGreen is to promote the development of European freight logistics in an environmentally friendly manner. Environmental factors play an increasing role in all transport modes, and holistic approaches are needed to identify win-win solutions. SuperGreen will evaluate a series of green corridors covering some representative regions and main transport routes throughout Europe. The selected corridors will be benchmarked based on parameters and key performance indicators covering all aspects related to transport operations and infrastructure. Environmental issues and emissions, external-, infrastructure- and internal costs will be covered to get an overall and realistic picture. Based on this benchmarking, areas and candidates for improvement will be identified (i.e. bottlenecks). The next step will be to evaluate how green technologies may support improving the identified bottlenecks. Among the green technologies considered may be novel propulsion systems, alternative fuels, cargo handling technologies, new terminal technologies or novel concepts relevant for the multimodal green corridors. The benchmarking issue is an iterative process. Next, a similar process needs to be accomplished taking into consideration smarter utilisation of available information in the multimodal chain (ICT-flows). An analysis will be made on how this information can be utilised to achieve greener logistics along the green corridors (e.g. e-freight, Supply Chain Management (SCM), smarter planning, scheduling and tracking & tracing). Based on these iterative benchmarks and evaluations, new R&D within specific topics may be needed to improve the identified bottlenecks. Recommendations for future calls for R&D proposals will be made. Last but not least, the project will review and assess the implications of alternative policy measures for green corridors, both at the local and the European level.

Global biodiversity is declining at an alarming rate and traditional conservation areas are no longer sufficient to slow this decline, so the potential contribution of managed land for conservation is increasingly acknowledged. This includes a broadening of the perspective from the field and farm to the landscape level, considering the often neglected spatial and temporal turnover in anthropogenic mosaic landscapes. Here we will use a highly replicated study design with the experimental exposure of standardized nesting resources to examine the relative importance of habitat type to landscape diversity using trap-nesting bees, wasps and their natural enemies. We will analyze the scale-dependence of partitioned biodiversity and quantify host-parasitoid and prey-predator interactions, as well as make food web statistics with a fully quantified interaction web (following Tylianakis et al. 2007, Nature 445: 2002-5). We will show how the major habitat types in our mosaic landscapes (and different years) contribute to overall species richness, comparing wheat, oilseed rape, grassland, field margin strips, fallows and forest margins, which represent a gradient of anthropogenic disturbance. We will examine how landscape composition influences the relative contribution of the six habitat types to species richness by focusing on a gradient of simple to complex structured landscapes. Further, we expect enemy richness to be related to host/prey mortality, so we will contribute to this highly debated topic. The mosaic structure of agricultural landscapes allow to study little known effects of landscape configuration, including spillover effects across habitats, inhibition of dispersal (by hostile cereal fields) and facilitation (by grassy corridors). Experiments with marked bee and wasp individuals allow to describe foraging behaviour and resource use across habitats.
This project is part of the large multidisciplinary CCES project RECORD (Assessment and Modeling of Coupled Ecological and Hydrological Dynamics in the Restored Corridor of the River Thur). It deals with the role of microbial transformations and plant uptake in the cycling of nitrogen in different functional processing zones of a restored section of river Thur. The results will help to gain a better understanding of the filter function of restored river corridors and of their potential to emit greenhouse gases. Main hypothesis: Nitrogen fluxes and transformations in floodplains strongly depend on the specific response of microorganisms and dominant plants in different functional processing zones to the hydrologic conditions that vary with season and flooding events. Objectives: At the example of a restored section of river Thur, we want to gain a better insight into the role of riparian systems as sink or source of nitrogen species and the potential risks for drinking water sources and atmosphere. Specific objectives: - quantify the rates of microbial nitrogen transformations within the model floodplain: comparison between different functional processing zones, temporal variations due to seasonal climatic and biological effects and flooding events, dependence on governing soil parameters (temperature, moisture, redox potential). - quantify the rates of nitrogen species uptake by model plants (Phalaris arundinacea, Salix alba): potential uptake depending on nutrient availability and nutrient balance; effects of plant age and and temporary flooding. - measure and model nitrogen species concentrations in the soil solution and nitrous oxide emissions: comparison between different functional processing zones, temporal variations due to seasonal climatic and biological effects and flooding events. Methods: - Sampling and monitoring plots with a diameter of 8m have been set-up in different functional processing zones: (i) pasture in a neighboring non-restored section, (ii) river-forest transect including weakly colonized gravel, gravel covered by fine over-bank material densely overgrown with reed grass (Phalaris arundinacea) and other herbaceous species, zone planted with willow (Salix alba) during the restoration, mixed deciduous forest dominated by ash, (iii) old riparian willow forest. - Microbial nitrogen transformation rates are determined from soil samples taken from within the plots at specific times. Mineralisation immobilisation turnover (MIT) is determined by isotopic dilution, potential denitrification by acetylen-inhibition incubation. - Specific nitrate and ammonium uptake rates by model plants are determined in hydroponic treatments in the climate chamber. - Soil respiration and trace gas efflux/influx is measured by in-situ gas sampling from within large rings permanently installed on the plots followed by GC analysis. Etc.
Introduction: Landscapes in Central Europe are constantly undergoing changes due to different land use claims. It is not known if there is an accelerated change close to main transportation routes. According to Swiss studies an increase of 36 percent - 87 percent in freight traffic and 16 percent - 31 percent in individual motorised traffic is forecasted on Swiss roads between 1997 and 2020. It is expected that the landscape already is an will be influenced more by the increasing traffic. Therefore the Monitoring Supporting Measures - Environment (MSM-E) concentrates on the effects of traffic on the environment along the main transit routes in Switzerland. Purpose: The purpose of this sub-project is to set up a monitoring for landscape changes along the transit routes. It includes finding the most suitable data sources and deriving indicators from them. Further the extent of the transit-corridor has to be defined. And to obtain first results we analyse the current state of the landscape an the retrospective changes wherever possible. Study Area: The study area is the landscape along the main transit routes A2 and A13 through the Swiss Alps. As control regions we chose The A1, which is also a motorway, but not a transit route. Stratification: We demarcate the potentially influenced landscape by using the relief that is the river catchment areas. We then attribute the the investigation area with the ecoregion, the motorway assignment and to rural or urban area. According to these criteria, the analyses are for these subregions. Indicators and Data Sources: The study area covers about of the Swiss landscape and touches around 20 cantons. Therefore and in order to observe the change regularly we build the monitoring on data sources which are available every few years for the whole of Switzerland. The derived indicators cover all land use classes. However, as the largest changes happen in the settlement and urban areas, we look at them in more detail. Analysis: Our focus lies on the distance analysis. We compare the distance zones and look whether there is a distance trend in the defined indicators. We further compare the different motorways and the different ecoregions and rural or urban areas to find similarities or disparities. Results: Preliminary results of the current state show that the landscape close to the motorways are stronger developed that further away or than the average of the corresponding ecoregion. This effect is also apparent if the relief is filtered off. The analysis of the retrospective changes show that this effect hardly depends on the distance only. Conclusions: The results show that the current landscape correlate to a great part with the distance to the motorway. It suggests that the motorway has influenced the landscape. However, if we look at the changes, the distance seems not to be such an essential factor.
