Research results in environmental and socio-economic sciences are often under-used by stakeholders involved in the management
of natural resources. To minimise this gap, the FP6 EU interdisciplinary project AquaTerra (AT) developed an end-users’ integration
methodology in order to ensure that the data, knowledge and tools related to the soil–water-sediment system that were generated
by the project were delivered in a meaningful way for end-users, thus improving their uptake. The methodology and examples
of its application are presented in this paper. From the 408 project deliverables, 96 key findings were identified, 53 related
to data and knowledge, and 43 describing advanced tools. River Basin Management (RBM) stakeholders workshops identified 8
main RBM issues and 25 specific stakeholders’ questions related to RBM which were classified into seven groups of cross-cutting
issues, namely scale, climate change, non-climatic change, the need for systemic approaches, communication and participation,
international and inter-basin coordination and collaboration, and the implementation of the Water Framework Directive. The
integration methodology enabled an assessment of how AT key findings meet stakeholders’ demands, and for each main RBM issue
and for each specific question, described the added-value of the AT project in terms of knowledge and tools generated, key
parameters to consider, and recommendations that can be made to stakeholders and the wider scientific community. Added value
and limitations of the integration methodology and its outcomes are discussed and recommendations are provided to further
improve integration methodology and bridge the gaps between scientific research data and their potential uptake by end-users. 相似文献
This work describes the design of novel Cu(II) complexes and their application in the photocatalytic degradation of methylene blue (MB). The same photocatalyst exhibits antibacterial activity against Escherichia coli (gram-negative) and Bacillus circulans (gram-positive). The characterisation of the photocatalysts has been done by several up-to-date physical methods. The rationale behind the photocatalysts’ beneficial intervention is discussed in this study. Statistical analysis of the degradation of MB is done using a one-way ANOVA, and the significance of means is determined by a multiple comparison test using Turkey HSD. Also, the degradation of MB follows pseudo first-order kinetics with high correlation coefficient values (R2?>?0.95), making them useful as simple and low-cost organic dye degradation agents.
Exploration of collaborative management implementation at two state wildlife agencies (SWAs) found that government fiscal accountability requirements create tensions that negatively impact collaborative plan implementation. Interview-derived insights highlight state policy misalignments between the support of collaborative governance and the application of governmental accountability controls. Tensions from this misalignment can negatively impact implementation and disrupt relationships among the SWA management staff, their partners, and their procurement staff. Rather than working as a part of a unified state interest to implement collaborative governance, procurement processes function as an internal regulatory authority that addresses different state policies. Informant comments identify dissimilar tension levels within the two SWAs, potentially due to the organizational location of procurement staffs. Confirmation of the influence of an SWA procurement staff organizational location on collaborative implementation requires further investigation. Tensions identified here likely exist in other natural resource management agencies and represent an understudied aspect of governmental collaborative management capacity often overlooked in collaborative planning and management scholarship. 相似文献
The main objective of this study was to investigate the capabilities of the receptor-oriented inverse mode Lagrangian Stochastic Particle Dispersion Model (LSPDM) with the 12-km resolution Mesoscale Model 5 (MM5) wind field input for the assessment of source identification from seven regions impacting two receptors located in the eastern United States. The LSPDM analysis was compared with a standard version of the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) single-particle backward-trajectory analysis using inputs from MM5 and the Eta Data Assimilation System (EDAS) with horizontal grid resolutions of 12 and 80 km, respectively. The analysis included four 7-day summertime events in 2002; residence times in the modeling domain were computed from the inverse LSPDM runs and HYPSLIT-simulated backward trajectories started from receptor-source heights of 100, 500, 1000, 1500, and 3000 m. Statistics were derived using normalized values of LSPDM- and HYSPLIT-predicted residence times versus Community Multiscale Air Quality model-predicted sulfate concentrations used as baseline information. From 40 cases considered, the LSPDM identified first- and second-ranked emission region influences in 37 cases, whereas HYSPLIT-MM5 (HYSPLIT-EDAS) identified the sources in 21 (16) cases. The LSPDM produced a higher overall correlation coefficient (0.89) compared with HYSPLIT (0.55-0.62). The improvement of using the LSPDM is also seen in the overall normalized root mean square error values of 0.17 for LSPDM compared with 0.30-0.32 for HYSPLIT. The HYSPLIT backward trajectories generally tend to underestimate near-receptor sources because of a lack of stochastic dispersion of the backward trajectories and to overestimate distant sources because of a lack of treatment of dispersion. Additionally, the HYSPLIT backward trajectories showed a lack of consistency in the results obtained from different single vertical levels for starting the backward trajectories. To alleviate problems due to selection of a backward-trajectory starting level within a large complex set of 3-dimensional winds, turbulence, and dispersion, results were averaged from all heights, which yielded uniform improvement against all individual cases. 相似文献
Thermally derived carbon fractions including organic carbon (OC) and elemental carbon (EC) have been reported for the U.S. Interagency Monitoring of PROtected Visual Environments (IMPROVE) network since 1987 and have been found useful in source apportionment studies and to evaluate quartz-fiber filter adsorption of organic vapors. The IMPROVE_A temperature protocol defines temperature plateaus for thermally derived carbon fractions of 140 degrees C for OC1, 280 degrees C for OC2, 480 degrees C for OC3, and 580 degrees C for OC4 in a helium (He) carrier gas and 580 degrees C for EC1, 740 degrees C for EC2, and 840 degrees C for EC3 in a 98% He/2% oxygen (O2) carrier gas. These temperatures differ from those used previously because new hardware used for the IMPROVE thermal/optical reflectance (IMPROVE_TOR) protocol better represents the sample temperature than did the old hardware. A newly developed temperature calibration method demonstrates that these temperatures better represent sample temperatures in the older units used to quantify IMPROVE carbon fractions from 1987 through 2004. Only the thermal fractions are affected by changes in temperature. The OC and EC by TOR are insensitive to the change in temperature protocol, and therefore the long-term consistency of the IMPROVE database is conserved. A method to detect small quantities of O2 in the pure He carrier gas shows that O2 levels above 100 ppmv also affect the comparability of thermal carbon fractions but have little effect on the IMPROVE_TOR split between OC and EC. 相似文献
