Learning lessons from the 2011 Van Earthquake to enhance healthcare surge capacity in Turkey

Historically, Turkey has adopted a reactive approach to natural hazards which resulted in significant losses. However, following the 1999 Kocaeli Earthquake, a more proactive approach has been adopted. This study aims to explore the way this new approach operates on the ground. A multinational and multidisciplinary team conducted a field investigation following the 2011 Van Earthquake to identify lessons to inform healthcare emergency planning in Turkey and elsewhere. The team interviewed selected stakeholders including, healthcare emergency responders, search and rescue services, ambulance services, and health authority representatives, in addition to conducting a focus group. Data were analysed according to an open coding process and SWOT (strength, weakness, opportunity, and threat) analysis. The findings suggest that the approach succeeded in developing a single vision by consolidating official efforts in a more structured way, mobilising many governmental and non-governmental organisations, securing significant amounts of resources including physical and human, and increasing the resilience and flexibility of infrastructure to expand its capacity. However, more attention is required to the development of stronger management procedures and acquisition of further resources.     

Bioavailability of permethrin and cyfluthrin in surface waters with low levels of dissolved organic matter

Pyrethroids are widely used insecticides in both agricultural and urban environments, and their potential movement to surface streams and toxicity to susceptible aquatic species is an emerging concern. Natural surface waters usually contain low levels of dissolved organic matter (DOM). Limited data have shown that DOM preparations can significantly alter the bioavailability and toxicity effects of pyrethroids. However, the importance of these effects in natural waters has not been investigated. In this study we measured uptake and acute toxicity of permethrin and cyfluthrin by Daphnia species in 15 surface water samples. Low levels of DOM (3-20 mg L(-1)) inhibited cyfluthrin uptake by Daphnia magna and acute toxicity to Ceriodaphnia dubia in most samples. For permethrin, the effects of DOM on bioavailability and toxicity were generally not significant. The effects of DOM on bioavailability of cyfluthrin could not be explained from the DOC concentration alone, suggesting that properties of DOM were also important in regulating bioavailability. Regression of K DOC with selected DOM properties revealed significant dependence of K DOC on the carboxylic acid content of DOM. Moreover, concentrations sensed by solid-phase microextraction (SPME) fibers were well correlated with the observed changes in bioaccumulation by D. magna and acute toxicity to C. dubia. Therefore, selective sampling methods such as SPME may be used for measuring the bioavailable concentrations of pyrethroids in waters with naturally occurring DOM levels and predicting the actual toxicity effects.     

Atmospheric xenon radioactive isotope monitoring

The Comprehensive Nuclear Test Ban Treaty (CTBT) organisation is implementing a world-wide monitoring network in order to check that the State Signatories comply with the treaty. One of the monitoring facilities consists of an atmospheric noble gas monitoring equipment. According to the requirements annexed in the treaty, the French Atomic Energy Commission (CEA) developed a device, called SPALAX, which automatically extracts xenon from ambient air and makes in situ measurements of the activities of four xenon radioisotopes (131mXe, 133mXe, 133Xe, 135Xe). The originality of this device is noticeable essentially in the gas sample processing method: thanks to the coupling of a gas permeator and of a noble gas specific adsorbent, it can selectively extract and concentrate xenon to more than 3 x 10 E6. This process is carried out continuously without cryogenic cooling, without any regeneration time. The detection of the xenon radioactive isotopes is done automatically by high spectral resolution gamma spectrometry, a robust technology well-suited for on-field instrumentation. In the year 2000, a prototype was involved in an international evaluation exercise directed by the CTBT organisation (CTBTO). This exercise demonstrated that the SPALAX equipment perfectly met the requirements of the CTBTO for such systems. On the basis of the continuous 24-h resolution record of the atmospheric xenon radioactive isotopes concentrations, the SPALAX system also demonstrated that ambient levels of 133Xe can fluctuate quickly from less than the detection limit to over 40 x 10(-3) Bq m(-3). In order to build an industrial version of this equipment, the CEA entered into a partnership with a French engineering company (S.F.I., Marseille, France), which is now able to produce an industrial version of SPALAX, i.e. more compact and more efficient than the prototypes. The 133Xe minimum detectable concentration is 0.15 x 10(-3) Bq m(-3) air per 24 h sampling cycle.     

“Alternative futures”: a methodology for integrated sustainability considerations,the case of Nuremberg West,Germany

In the context of the desire to steer urban transformation towards sustainability transition, the development of proposals for alternative futures assists policy-makers and practitioners in focusing on impact by organising the various drivers, particularly spatial ones that cause an interactive urban system to transit. This paper presents the methodology that has been developed by the Chair for Urban Development, Munich University of Technology (TUM) as it was working within an inter-disciplinary research team on a project commissioned by the municipality of Nuremberg. The objective of this project was to develop ideas for regenerating the formerly industrial area of Nuremberg West (NW) under the guiding theme of sustainable urban development. This methodology focuses on the development of proposals of positive and possible transformations of NW in the year 2050 based on the analysis of economy, housing and space at various scales and a systematic assessment of trends. These alternative futures became framing and guiding narratives to internalise and anchor the debate in-between the various disciplines involved in this project.     

When Environmental Action Does Not Activate Concern: The Case of Impaired Water Quality in Two Rural Watersheds

Little research has considered how residents’ perceptions of their local environment may interact with efforts to increase environmental concern, particularly in areas in need of remediation. This study examined the process by which local environmental action may affect environmental concern. A model was presented for exploring the effects of community-based watershed organizations (CWOs) on environmental concern that also incorporates existing perceptions of the local environment. Survey data were collected from area residents in two watersheds in southwestern Pennsylvania, USA, an area affected by abandoned mine drainage. The findings suggest that residents’ perceptions of local water quality and importance of improving water quality are important predictors of level of environmental concern and desire for action; however, in this case, having an active or inactive CWO did not influence these perceptions. The implications of these findings raise important questions concerning strategies and policy making around environmental remediation at the local level.     

Managing Protected Areas Under Climate Change: Challenges and Priorities

The implementation of adaptation actions in local conservation management is a new and complex task with multiple facets, influenced by factors differing from site to site. A transdisciplinary perspective is therefore required to identify and implement effective solutions. To address this, the International Conference on Managing Protected Areas under Climate Change brought together international scientists, conservation managers, and decision-makers to discuss current experiences with local adaptation of conservation management. This paper summarizes the main issues for implementing adaptation that emerged from the conference. These include a series of conclusions and recommendations on monitoring, sensitivity assessment, current and future management practices, and legal and policy aspects. A range of spatial and temporal scales must be considered in the implementation of climate-adapted management. The adaptation process must be area-specific and consider the ecosystem and the social and economic conditions within and beyond protected area boundaries. However, a strategic overview is also needed: management at each site should be informed by conservation priorities and likely impacts of climate change at regional or even wider scales. Acting across these levels will be a long and continuous process, requiring coordination with actors outside the “traditional” conservation sector. To achieve this, a range of research, communication, and policy/legal actions is required. We identify a series of important actions that need to be taken at different scales to enable managers of protected sites to adapt successfully to a changing climate.
