The team members will pay regular visits to these hospitals and send reports to the department, the state government said in an order.

Compact X-ray sources based on inverse Compton scattering provide brilliant and partially coherent X-rays in a laboratory environment. The cross section for inverse Compton scattering is very small, requiring high-power laser systems as well as small laser and electron beam sizes at the interaction point to generate sufficient flux. Therefore, these systems are very sensitive to distortions which change the overlap between the two beams. In order to monitor X-ray source position, size and flux in parallel to experiments, the beam-position monitor proposed here comprises a small knife edge whose image is acquired with an X-ray camera specifically designed to intercept only a very small fraction of the X-ray beam. Based on the source position drift recorded with the monitor, a closed-loop feedback stabilizes the X-ray source position by adjusting the laser beam trajectory. A decrease of long-term source position drifts by more than one order of magnitude is demonstrated with this device. Consequently, such a closed-loop feedback system which enables stabilization of source position drifts and flux of inverse Compton sources in parallel to experiments has a significant impact on the performance of these sources.

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

Monitoring the effects of chemicals in the human body provides useful data for assessing and managing environmental risks to health, but it also raises ethical questions about how the results of such studies should be reported to participants. New research suggests that changes are needed to the research process to allow study participants to play a greater role in interpreting, disseminating and using the results.

Published to mark the 20th anniversary of the Habitats Directive, this latest Thematic issue examines the challenges and successes in managing and restoring biodiversity in the Natura 2000 network.

Networks of wireless sensors could be used to monitor traffic noise. A new study shows that the wifi sensor systems, although slightly less accurate than precision noise monitoring systems, can provide detailed information, with dense coverage, about traffic noise over a longer period. Their low cost and low energy requirements make them particularly suitable and attractive for use by local authorities or even community groups.

Monitored natural attenuation (MNA) is a long-term, ‘hands-off’ approach to cleaning up contaminated land. New research has surveyed the current development of MNA in Europe and demonstrates a clear need for practitioners to systematically collect and learn from each other’s experiences with this form of brownfield remediation.

This Thematic Issue provides a flavour of recent work by scientists in the area of biodiversity monitoring to highlight both up-to-date approaches to conservation and evaluation, and how long-term monitoring data could be used more effectively in management and policy decisions.

In-depth soil information is increasingly required to achieve an array of environmental and economic goals. In particular, accurate estimates of soil carbon stocks are necessary to guide land-management practices and climate- related policymaking. To help meet this need, Australian scientists have developed a new sensing method to analyse cylindrical soil samples (soil cores), known as the Soil Condition ANalysis System (SCANS). By integrating a novel automated soil- core sensing system (CSS) with advanced statistical analytics and modelling, the SCANS provides a level of detail that is difficult to achieve with existing alternatives. SCANS is not only rapid, accurate and inexpensive1, but is likely to be a useful tool for farmers, land managers and policymakers, as the improved assessment of soil functions, structures and carbon stocks will facilitate more informed, sustainable decision-making.

Using open-access software and power saving technologies, researchers have developed an easily deployed, low-cost network for monitoring large areas of the Amazon rainforest. This Peruvian study shows that environmental information, such as soil moisture and rates of photosynthesis, can be recorded and uploaded to the internet without having to make repeated visits to remote areas.

Effective regulation of genetically modified organisms (GMOs) calls for monitoring of the potential environmental risks. This study explored whether the German permanent soil monitoring programme could be a useful tool for this purpose. The researchers say the programme has potential to monitor the effects of GMOs on local soil communities, but that adaptations would be necessary.

Recent work in the coastal Mediterranean waters of the ‘Comunidad Valencia’ in Eastern Spain confirms that wastewater treatment plants (WWTPs) are a significant source of pollutants that need monitoring under the Water Framework Directive (WFD) and Priority Substances Directive. However, these substances also directly enter coastal waters from mixed urban, industrial and agricultural sources, creating a challenge for the development of control measures.

Algal blooms in inland and marine waters could be detected and monitored more accurately in future, thanks to a new assessment method. Scientists have developed a new algorithm for sensors which identify emerging blooms of cyanobacteria based on the behaviour of light reflected by the algae’s pigment. Importantly, the algorithm may reduce uncertainty in estimations of algal concentrations by distinguishing between two different types of pigment.

Sustainable river management is increasingly informed by hydromorphological stream assessments — evaluations and classifications of stream conditions which account for both hydrological (the movement, distribution and quantity of water) and geomorphological (the processes and forms deriving from the interactions of water and sediment movement) features. In order to provide a more accurate and comprehensive assessment of river character and dynamics, scientists have developed three novel methods. Together, these tools represent a promising technique for conducting collaborative assessment and monitoring of river conditions in Europe.

Restoring ecosystems in estuaries and along coasts is an important part of European environmental policy. A new analysis of degraded ecosystems has indicated that, although some restoration can take less than five years, when there has been a century of degradation, it can take a minimum of 15-25 years.

New research has explored how well different governance systems can achieve desirable conservation outcomes. Results confirmed the importance of adaptive management, which relies on regular monitoring to enable 'learning through doing' to refine actions, and suggested that leadership using expert knowledge was also significant in successful governance.

To encourage protection of the environment, payments for environmental services (PES) schemes offer direct incentives to individuals and communities to maintain or improve the provision of environmental services. A recent study suggests indicators to monitor PES must be chosen very carefully to help ensure that monitoring does not cost more than the payments themselves.

The first ever European-wide study of bird monitoring practices reveals a wide range of monitoring protocols. The researchers provide recommendations for improving bird monitoring programmes, in particular, for those involving large numbers of volunteers.
