Reframing water: Contesting H2O within the European Union

AbstractWater fulfills multiple functions and is instilled with numerous meanings: it is concurrently an economic input, an aesthetic reference, a religious symbol, a public good, a fundamental resource for public health, and a biophysical need for humans and ecosystems. Hence, water has multiple ontologies embedded within diverse social, cultural, spiritual, and political domains. For this paper, we reviewed 78 pieces of water legislation across the European Union, critically analysing the different ways in which water has been defined; subsequently we contrasted these definitions against the European Union Water Framework Directive (WFD). We argue that the act of defining water is not only a deeply social and political process, but that it often privileges specific worldviews; and that the impetus of the WFD reveals a neoliberal approach to water governance: an emphasis on water as a commercial product that should be subjected to market influences. Subsequently, we conclude that the emerging concept of the ’hydrosocial cycle,’ which emphasises the inherent links between water and society, could be a useful heuristic tool to promote a broader conception of water based on diverse understandings, that challenge hegemonic definitions of water

Impacts of tourism on coastal areas

The socioeconomics of the Anthropocene are exposing coastal regions to multiple pressures, including climate change hazards, resource degradation, urban development, and inequality. Tourism is often raised as either a panacea to, or exacerbator of, such threats to ecosystems and sustainable livelihoods. To better understand the impacts of tourism on coastal areas, Scopus and Web of Science databases were searched for the top-100 cited papers on coastal tourism. Web of Science suggested ‘highly cited’ papers were also included to allow for more recent high impact papers. Of the papers retrieved, forty-four focused on the impacts of tourism. Social/cultural and environmental impacts were viewed as mostly negative, while economic impacts were viewed as mostly positive but only of actual benefit to a few. In addition, when compared with recent whole-of-sector reviews and reports it was evident that coastal tourism is increasingly a global enterprise dominated by large corporations that leverage various interests across local to transnational scales. Through this global enterprise, even the positive economic benefits identified were overshadowed by a broader system of land and property development fuelling local wealth inequity and furthering the interests of offshore beneficiaries. Only two highly cited papers discussed tourism within a broader context of integrated coastal zone management, suggesting that tourism is mostly assessed as a discrete sector within the coastal zone and peripheral to other coastal management considerations or the global tourism sector as a whole. The findings have relevance to the holistic management of coasts, coastal tourism, and the achievement of sustainable development goals in a way that considers the increasing threats from coastal hazards, resource extraction and urbanisation, as well as the pervasive impacts of international business systems from local to global scales

Global Water Governance and Climate Change: Identifying Innovative Arrangements for Adaptive Transformation

A convoluted network of different water governance systems exists around the world. Collectively, these systems provide insight into how to build sustainable regimes of water use and management. We argue that the challenge is not tomake the systemless convoluted, but rather to support positive and promising trends in governance, creating a vision for future environmental outcomes. In this paper, we analyse nine water case studies from around the world to help identify potential ‘innovative arrangements’ for addressing existing dilemmas. We argue that such arrangements can be used as a catalyst for crafting new global water governance futures. The nine case studies were selected for their diversity in terms of location, scale and water dilemma, and through an examination of their contexts, structures and processes we identify key themes to consider in the milieu of adaptive transformation. These themes include the importance of acknowledging socio-ecological entanglements, understanding the political dimensions of environmental dilemmas, the recognition of different constructions of the dillema, and the importance of democratized processes.The research for this paper is a part of the “CADWAGO: Climate change adaptation and water governance—reconciling food security, renewable energy and the provision of multiple ecosystem services” project funded as part of the “Europe and Global Challenges programme” by Compagnia di San Paolo, VolkswagenStiftung and Riksbankens Jubileumsfond.https://www.mdpi.com/2073-4441/10/1/2

Maternal and paternal genomes differentially affect myofibre characteristics and muscle weights of bovine fetuses at midgestation

Postnatal myofibre characteristics and muscle mass are largely determined during fetal development and may be significantly affected by epigenetic parent-of-origin effects. However, data on such effects in prenatal muscle development that could help understand unexplained variation in postnatal muscle traits are lacking. In a bovine model we studied effects of distinct maternal and paternal genomes, fetal sex, and non-genetic maternal effects on fetal myofibre characteristics and muscle mass. Data from 73 fetuses (Day153, 54% term) of four genetic groups with purebred and reciprocal cross Angus and Brahman genetics were analyzed using general linear models. Parental genomes explained the greatest proportion of variation in myofibre size of Musculus semitendinosus (80–96%) and in absolute and relative weights of M. supraspinatus, M. longissimus dorsi, M. quadriceps femoris and M. semimembranosus (82–89% and 56–93%, respectively). Paternal genome in interaction with maternal genome (P<0.05) explained most genetic variation in cross sectional area (CSA) of fast myotubes (68%), while maternal genome alone explained most genetic variation in CSA of fast myofibres (93%, P<0.01). Furthermore, maternal genome independently (M. semimembranosus, 88%, P<0.0001) or in combination (M. supraspinatus, 82%; M. longissimus dorsi, 93%; M. quadriceps femoris, 86%) with nested maternal weight effect (5–6%, P<0.05), was the predominant source of variation for absolute muscle weights. Effects of paternal genome on muscle mass decreased from thoracic to pelvic limb and accounted for all (M. supraspinatus, 97%, P<0.0001) or most (M. longissimus dorsi, 69%, P<0.0001; M. quadriceps femoris, 54%, P<0.001) genetic variation in relative weights. An interaction between maternal and paternal genomes (P<0.01) and effects of maternal weight (P<0.05) on expression of H19, a master regulator of an imprinted gene network, and negative correlations between H19 expression and fetal muscle mass (P<0.001), suggested imprinted genes and miRNA interference as mechanisms for differential effects of maternal and paternal genomes on fetal muscle.Ruidong Xiang, Mani Ghanipoor-Samami, William H.

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Ecological restoration and management of the Linwood paddocks

This study investigates salt marsh restoration within the Canterbury region as a way to remedy the current loss of these vital systems. Previous attempts have concentrated largely on aesthetic appeal and lack detailed scientific basis or understanding. The proposed Linwood Paddock restoration site (historically a brackish wetland) provides an excellent opportunity for scientifically-based salt marsh restoration. Restoration should reestablish functions and attributes symptomatic of a 'healthy' wetland system, from the presently imposed pastoral system. The historic and current salt marsh composition and relation to environmental conditions are described for the Canterbury region and the long-term impacts of implementation and management decisions in restoration are evaluated. The likely success of plant growth on heavy metal and nutrient-enriched Linwood soils and the potential for phytoremediation to improve wastewater quality are also determined. Quantitative survey's of the fragmented Avon, Heathcote, Brooklands and Saltwater Creek salt marshes, provided a complete revegetation template, which details the optimal range for each native species with respect to elevation and salinity. The marked zonation appeared to be the result of both competitive displacement and interspecific variation in physiological tolerance. Lower marsh elevations were dominated by Leptocarpus similis and upper marsh elevations by Sarcocornia quinqueflora. All other species' requirements overlap, but they would be expected to exist in a mid tidal mosaic "patchwork" fashion in revegetation, since the clonal nature of these species means that patches will be mono specific, rather than mixed-species patches. A mesocosm experiment was performed in an area of the Heathcote marsh by planting Leptocarpus similis, Juncus maritimus and Schoenoplectus pungens into transferred Linwood Paddock soil. Plant growth was viable in Linwood Paddock topsoil and plants sourced from natural stocks had significantly higher survival and biomass than nursery stock (p < 0.05). In addition, there was a significant difference (p < 0.05) in survival and biomass between the two species remaining at the end of the experiment, with Leptocarpus similis having increased survival and greater biomass than Juncus maritimus. Assessments of previous local revegetation attempts at the margins of Oxidation Pond Nos. 5 and 6, the Charlesworth Street Reserve and the Devil's Elbow bankworks showed that salt marsh herbs (Sarcocornia quinqueflora in particular) were more likely to self-colonise a restoration site than rushes or sedges. The most obvious impediments to revegetation success were the use of a too coarse substrate and insufficient tidal flushing through lack of maintenance. It was concluded that adequate monitoring and record-keeping are necessary to determine strategies for wetland implementation and to understand the long-term impacts of wetland management decisions from such attempts. The scientific research was integrated in the design of an ecological salt marsh restoration and management plan for the Linwood Paddocks, which is not only representative of Canterbury salt marshes, but also self-sustaining and accessible to the general public. Creation of a freshwater wetland within the existing Bromley Oxidation Ponds is presented as a unique opportunity to remediate wastewater and to supply high quality freshwater to the salt marsh restoration, thereby enhancing estuary wildlife and water quality values simultaneously. The freshwater species recommended for phytoremediation are Typha and Scirpus. This design is scientifically based and its principles could be used (with the application of local data) in further restoration projects within New Zealand or elsewhere in the temperate world. As salt marshes decline, this approach is timely to ensure that restoration is successful and not a technique that is relearned each time

Seeing is questioning: prompting sustainability discourses through an evocative visual agenda

I explore the potential utility of visual imagery to engage viewers in connecting ways with dynamic social-ecological contexts. Constructing photographs in response to the mass stranding of birds (shearwaters) on the east coast of Australia in 2013, I demonstrate the potential of wildlife and landscape photography to represent the impacts of environmental change at personal, relational, spatial, and temporal scales simultaneously. In so doing, I suggest that the production and interpretation of photographs can lead to responses that: (1) foster attentive forms of vision in familiar contexts; (2) provoke reflexive self-examination and critiques of broader, complex systems; (3) develop emotional connections with those impacted by social-ecological change; and (4) provide a foundation for precautionary behavioral change in uncertain contexts. Consequently, 'seeing' is reconceptualized as questioning, not believing, and as a valuable contribution to learning for sustainability and resilience
