“…This provides a basis for improvement of the water risk management capacity of local government authorities. Hence, the SUSTAIN H 2 O project will serve as an excellent opportunity for China to deal with POP-related water body pollution through the shared research and engineering expertise of its European partners and will strengthen existing scientific cooperation between China and the EU (Chen et al 2015).…”

“…The severity of environmental contamination in the Taihu region as well as in China in general is recognized since many years and led to a high number of research and management actions [5, 15, 17]. Despite numerous restoration efforts, the water quality of Taihu still remains impaired [6].…”

The Taihu (Tai lake) region is one of the most economically prospering areas of China. Due to its location within this district of high anthropogenic activities, Taihu represents a drastic example of water pollution with nutrients (nitrogen, phosphate), organic contaminants and heavy metals. High nutrient levels combined with very shallow water create large eutrophication problems, threatening the drinking water supply of the surrounding cities. Within the international research project SIGN (SinoGerman Water Supply Network, www.water-sign.de), funded by the German Federal Ministry of Education and Research (BMBF), a powerful consortium of fifteen German partners is working on the overall aim of assuring good water quality from the source to the tap by taking the whole water cycle into account: The diverse research topics range from future proof strategies for urban catchment, innovative monitoring and early warning approaches for lake and drinking water, control and use of biological degradation processes, efficient water treatment technologies, adapted water distribution up to promoting sector policy by good governance. The implementation in China is warranted, since the leading Chinese research institutes as well as the most important local stakeholders, e.g. water suppliers, are involved.

“…Central China is no exception to this; however, this is an extremely interesting area as it hosts the transitional area between subtropics and the warm temperate biogeographic zones, thus representing an important zone for biodiversity (Myers et al 2000). China faces severe problems in providing adequate drinking water in terms of both quality and quantity, as well as sufficient water to maintain a high agricultural production level for food security; these requirements dominate daily decisions on water management (Chen et al 2015). Water abstraction is one of the primary stressors in Chinese freshwater ecosystems (mainly large rivers, groundwater, reservoirs), along with chemical and organic pollution.…”

Chinese rivers are both highly biodiverse and highly under pressure, hence an urgent need exists to understand ecological drivers and disentangle different scales of stressors to support water management. Our aims were to (1) determine the most influential variables for benthic invertebrate occurrence, (2) compare results related to communities as opposed to metrics and (3) examine the role of spatial scales with relevance to management. Benthic invertebrate sampling was performed at 37 sites in selected tributaries of the middle reaches of the Yangtze, covering an environmental gradient with a focus on organic pollution (stratified sampling design). Ten metrics commonly used in biomonitoring were derived and analysed in parallel to assemblage data. Environmental variables covered 74 parameters from three different spatial scales, namely local, reach and catchment scale. We ran a CCA with each of the three subsets to find out the significant determining/explanatory variables, followed by pCCA and pRDA (for metric data) with these variables with forward selection to determine single variables important for each subset; we further used variation portioning for benthic invertebrate data. A high percentage of overall variability (70 %) of the assemblage structure was explained, with catchment-and local-scale variables being almost equally important. Small-scale variables tended to be more important than large-scale variables for the metric-based approach but not for the assemblage approach. Our results emphasise the need for spatially explicit regional studies in freshwater systems and suggest testing multi-metric assessment approaches to tackle water management and environmental health questions in China.
