Academic literature on the topic 'Land degradation Victoria Measurement Case studies'

Ecological systems are essential in maintaining a good living environment for human beings. However, human beings usually focus on the benefits they can gain from the ecosystem by developing the land and ignore the degradation of environment. In this paper, we will offer an ecological services evaluation model to measure the value of ecological services and provide land use planners with a method to compute the true economic costs of the land use development projects. First, we define ecological services value (ESV), which means the value of the benefits that ecosystem can provide. Then, we classify the functions of ecosystem into five kinds: water purification, climate regulation, air purification, biodiversity conservation and vegetation conservation. For each function, we choose a related index to measure the performance. After the classification, we adopt Analytical Hierarchy Process (AHP) to calculate the weight for each of the function and do the consistency test; second, we apply knowledge of economics to study the true economic costs; third, after getting the equation of the true economic costs, we realize it in the cost-benefit analysis. We offer two case studies to analyze the small community-sized project and large national project respectively; fourth, we take ten examples including U.S., Switzerland and China to apply our model in practice. We fit data and find the average level of land use percent over time, and form a model with differential equation in order to calculate the time-varying model of ESV; fifth, we focus on humanities field to explore the impacts on land use project planners and managers. They should not only be responsible for environmental degradation and monitor environmental index carefully, but also pay for the benefits which were ever owned by human beings before land development. In order to make our work more accurate and complete, we use SWOT Analysis across the analytical process. Finally, we promote our model and extend the factors from six to twelve, which increases the accuracy.

Knowledge of the amount of bank filtrate in raw water is crucial for drinking water suppliers using water wells in close proximity to rivers, in particular if those rivers are strongly affected by anthropogenic activities, e.g. receiving effluents from waste water treatment plants. Analysis of organic micropollutants as tracer compounds is costly and time-consuming, and results may be biased by processes such as sorption, degradation or even by other input pathways such as land use activities. In this study, the use of gadolinium (Gd) as an alternative conservative tracer to indicate the amount of bank filtrate in raw water from drinking water wells close to rivers was investigated. In two case studies in Germany and Luxembourg, river water and water from drinking water wells at several distances from the rivers was sampled and analysed for anthropogenic Gd as well as for some of the organic trace pollutants conventionally used as tracer compounds. The amount of bank filtrate as calculated from Gd was compared with the estimates derived by conventional tracers and by hydrological flux modelling. The results indicated that the measurement of Gd may provide a promising alternative to monitor infiltration of river water in ground water used for production of drinking water.

Abstract. The adage: “There is no such thing as a free lunch”, is relevant to land-use hydrology in Australia. Changes in land use to achieve greater productivity of food and fibre may have an adverse effect on the water balance and hence on the natural resource capital of a catchment. An altered regime of catchment outflow accompanies those land-use changes which, together with land degradation, impairs available water resources in quantity and quality and threatens enterprise sustainability, notwithstanding the initial improvement in productivity. Central to any hydrological change is an altered pattern of seasonal and annual water use by vegetation that has become modified in function with an amended transpiration fraction of daily evapotranspiration. In Australia, since measurement of evapotranspiration became feasible, the hydrological consequences of changes in land use have been determined, allowing the benefits in terms of plant productivity achieved through enhanced water use efficiency to be weighed against changed catchment outflows, diminished in either quantity or quality. Four case studies are presented as examples of ecological and hydrological changes: two deal with the upland forest environment and two with arable lowlands. In an upland eucalypt forest, following wildfire with subsequent regeneration from natural seedling establishment, substantial reduction in water yield occurred throughout a 50-year period of succession in the even-aged stand. In comparison, the effect of converting eucalypt forest to pine plantations was less detrimental to the yield of water from the catchments, with substantial growth increases over 30 years. In the lowlands, agricultural productivity, both as annual pasture and as crop, far exceeds that of natural perennial grassland and woodland. This increase in productivity comes not so much from any change to the yield of total water outflow but at the expense of water quality, compromised with increased material transport in suspension and solution resulting from accelerated erosion in association with outbreaks of soil salinity and acidity. The present study is aimed at optimising management to give plant production outcomes that ensure environmental protection through resource conservation. In the uplands, harvesting of water is the dominant consideration so that conservative management with limited plant productivity is sought. In the lowlands, the objective is to devise novel ecosystems with profitable plant production that exercises due control on outflow in maintaining the chemical and physical integrity of the edaphic environment.

Abstract. Hartati W, Sudarmadji T. 2022. The dynamics of soil carbon in revegetated post-coal mining sites: A case study in Berau, East Kalimantan, Indonesia. Biodiversitas 23: xxxx. Open pit mining practices cause the loss of vegetation cover as well as soil degradation. Post-mining land reclamation and revegetation are therefore enforced to recover the vegetation and soil quality. While several studies have revealed vegetation succession following post-mining revegetation, limited studies have focused on the carbon dynamics of the soil. This study aimed to investigate the dynamics of soil carbon stock due to mining operations and how it changed following revegetation. The research was carried out in the concession area of a coal mining company in Berau, East Kalimantan, which was divided into three sites: Sambarata Mining Operation (SMO) Site, Binungan Mining Operation (BMO) Site, and Lati Mining Operation (LMO) Site. At each site, eight research measurement plots (RMP) were established representing land with varying vegetational conditions, namely original land and post-mined lands with varying revegetation stages from open land to 12-year-old vegetation. The percentage of C content was calculated from 288 disturbed soil samples, while bulk density was analyzed from 144 whole soil samples using the Walkey & Black and gravimetric methods. We found that the C stock at the initial state after the mining operation was very low. Coal mining activities caused a loss of C in soil with an average value of 21.29%, or equal to 5.65 tons/ha. The biggest loss occurred at the SMO site (44.97%, or 13.04 tons/ha), while the smallest loss was found at the LMO site (2.24%, or 0.40 tons/ha). The carbon stock improved after revegetation, particularly in the SMO and LMO sites, and the rate of carbon stock enhancement in the soil differed across sites. The results also showed that soil carbon in the post-mining area of 10-30 cm was greater than that of the 0-10 cm layer. Along with the increasing age of plants, the vertical distribution of C stock shifted from the lower layer to the upper layer.

Special Care NoticeThis article discusses trauma and violence inflicted upon the Indigenous peoples of Tasmania through the processes of colonisation. Content within this article may be distressing to some readers. IntroductionThis article looks briefly at the collection, consultation, and digital sharing of stories essential to the histories of the First Nations peoples of Australia. Focusing on materials held in Sydney, New South Wales two case studies—the object known as the Proclamation Board and the George Augustus Robinson Papers—explore how materials can be shared with Aboriginal peoples of the region now known as Tasmania. Specifically, the authors of this article (a Palawa man and an Australian woman of European descent) ask how can the idea of the privileging of Indigenous voices, within Eurocentric cultural collections, be transformed from rhetoric to reality? Moreover, how can we navigate this complex work, that is made even more problematic by distance, through the utilisation of knowledge networks which are geographically isolated from the collections holding stories crucial to Indigenous communities? In seeking to answer these important questions, this article looks at how cultural, emotional, and intellectual ownership can be divested from the physical ownership of a collection in a way that repatriates—appropriately and sensitively—stories of Aboriginal Australia and of colonisation. Holding Stories, Not Always Our OwnCultural institutions, including libraries, have, in recent years, been drawn into discussions centred on the notion of digital disruption and “that transformative shift which has seen the ongoing realignment of business resources, relationships, knowledge, and value both facilitating the entry of previously impossible ideas and accelerating the competitive impact of those same impossible ideas” (Franks and Ensor n.p.). As Molly Brown has noted, librarians “are faced, on a daily basis, with rapidly changing technology and the ways in which our patrons access and use information. Thus, we need to look at disruptive technologies as opportunities” (n.p.). Some innovations, including the transition from card catalogues to online catalogues and the provision of a wide range of electronic resources, are now considered to be business as usual for most institutions. So, too, the digitisation of great swathes of materials to facilitate access to collections onsite and online, with digitising primary sources seen as an intermediary between the pillars of preserving these materials and facilitating access for those who cannot, for a variety of logistical and personal reasons, travel to a particular repository where a collection is held.The result has been the development of hybrid collections: that is, collections that can be accessed in both physical and digital formats. Yet, the digitisation processes conducted by memory institutions is often selective. Limited resources, even for large-scale digitisation projects usually only realise outcomes that focus on making visually rich, key, or canonical documents, or those documents that are considered high use and at risk, available online. Such materials are extracted from the larger full body of records while other lesser-known components are often omitted. Digitisation projects therefore tend to be devised for a broader audience where contextual questions are less central to the methodology in favour of presenting notable or famous documents online only. Documents can be profiled as an exhibition separate from their complete collection and, critically, their wider context. Libraries of course are not neutral spaces and this practice of (re)enforcing the canon through digitisation is a challenge that cultural institutions, in partnerships, need to address (Franks and Ensor n.p.). Indeed, our digital collections are as affected by power relationships and the ongoing impacts of colonisation as our physical collections. These power relationships can be seen through an organisation’s “processes that support acquisitions, as purchases and as the acceptance of artefacts offered as donations. Throughout such processes decisions are continually made (consciously and unconsciously) that affect what is presented and actively promoted as the official history” (Thorpe et al. 8). While it is important to acknowledge what we do collect, it is equally important to look, too, at what we do not collect and to consider how we continually privilege and exclude stories. Especially when these stories are not always our own, but are held, often as accidents of collecting. For example, an item comes in as part of a larger suite of materials while older, city-based institutions often pre-date regional repositories. An essential point here is that cultural institutions can often become comfortable in what they collect, building on existing holdings. This, in turn, can lead to comfortable digitisation. If we are to be truly disruptive, we need to embrace feeling uncomfortable in what we do, and we need to view digitisation as an intervention opportunity; a chance to challenge what we ‘know’ about our collections. This is especially relevant in any attempts to decolonise collections.Case Study One: The Proclamation BoardThe first case study looks at an example of re-digitisation. One of the seven Proclamation Boards known to survive in a public collection is held by the Mitchell Library, State Library of New South Wales, having been purchased from Tasmanian collector and photographer John Watt Beattie (1859–1930) in May 1919 for £30 (Morris 86). Why, with so much material to digitise—working in a program of limited funds and time—would the Library return to an object that has already been privileged? Unanswered questions and advances in digitisation technologies, created a unique opportunity. For the First Peoples of Van Diemen’s Land (now known as Tasmania), colonisation by the British in 1803 was “an emotionally, intellectually, physically, and spiritually confronting series of encounters” (Franks n.p.). Violent incidents became routine and were followed by a full-scale conflict, often referred to as the Black War (Clements 1), or more recently as the Tasmanian War, fought from the 1820s until 1832. Image 1: Governor Arthur’s Proclamation to the Aborigines, ca. 1828–1830. Image Credit: Mitchell Library, State Library of New South Wales, Call No.: SAFE / R 247.Behind the British combatants were various support staff, including administrators and propagandists. One of the efforts by the belligerents, behind the front line, to win the war and bring about peace was the production of approximately 100 Proclamation Boards. These four-strip pictograms were the result of a scheme introduced by Lieutenant Governor George Arthur (1784–1854), on the advice of Surveyor General George Frankland (1800–38), to communicate that all are equal under the rule of law (Arthur 1). Frankland wrote to Arthur in early 1829 to suggest these Proclamation Boards could be produced and nailed to trees (Morris 84), as a Eurocentric adaptation of a traditional method of communication used by Indigenous peoples who left images on the trunks of trees. The overtly stated purpose of the Boards was, like the printed proclamations exhorting peace, to assert, all people—black and white—were equal. That “British Justice would protect” everyone (Morris 84). The first strip on each of these pictogram Boards presents Indigenous peoples and colonists living peacefully together. The second strip shows “a conciliatory handshake between the British governor and an Aboriginal ‘chief’, highly reminiscent of images found in North America on treaty medals and anti-slavery tokens” (Darian-Smith and Edmonds 4). The third and fourth strips depict the repercussions for committing murder (or, indeed, any significant crime), with an Indigenous man hanged for spearing a colonist and a European man hanged for shooting an Aboriginal man. Both men executed in the presence of the Lieutenant Governor. The Boards, oil on Huon pine, were painted by “convict artists incarcerated in the island penal colony” (Carroll 73).The Board at the State Library of New South Wales was digitised quite early on in the Library’s digitisation program, it has been routinely exhibited (including for the Library’s centenary in 2010) and is written about regularly. Yet, many questions about this small piece of timber remain unanswered. For example, some Boards were outlined with sketches and some were outlined with pouncing, “a technique [of the Italian Renaissance] of pricking the contours of a drawing with a pin. Charcoal was then dusted on to the drawing” (Carroll 75–76). Could such a sketch or example of pouncing be seen beneath the surface layers of paint on this particular Board? What might be revealed by examining the Board more closely and looking at this object in different ways?An important, but unexpected, discovery was that while most of the pigments in the painting correlate with those commonly available to artists in the early nineteenth century there is one outstanding anomaly. X-ray analysis revealed cadmium yellow present in several places across the painting, including the dresses of the little girls in strip one, uniform details in strip two, and the trousers worn by the settler men in strips three and four (Kahabka 2). This is an extraordinary discovery, as cadmium yellows were available “commercially as an artist pigment in England by 1846” and were shown by “Winsor & Newton at the 1851 Exhibition held at the Crystal Palace, London” (Fiedler and Bayard 68). The availability of this particular type of yellow in the early 1850s could set a new marker for the earliest possible date for the manufacture of this Board, long-assumed to be 1828–30. Further, the early manufacture of cadmium yellow saw the pigment in short supply and a very expensive option when compared with other pigments such as chrome yellow (the darker yellow, seen in the grid lines that separate the scenes in the painting). This presents a clearly uncomfortable truth in relation to an object so heavily researched and so significant to a well-regarded collection that aims to document much of Australia’s colonial history. Is it possible, for example, the Board has been subjected to overpainting at a later date? Or, was this premium paint used to produce a display Board that was sent, by the Tasmanian Government, to the 1866 Intercolonial Exhibition in Melbourne? In seeking to see the finer details of the painting through re-digitisation, the results were much richer than anticipated. The sketch outlines are clearly visible in the new high-resolution files. There are, too, details unable to be seen clearly with the naked eye, including this warrior’s headdress and ceremonial scarring on his stomach, scars that tell stories “of pain, endurance, identity, status, beauty, courage, sorrow or grief” (Australian Museum n.p.). The image of this man has been duplicated and distributed since the 1830s, an anonymous figure deployed to tell a settler-centric story of the Black, or Tasmanian, War. This man can now be seen, for the first time nine decades later, to wear his own story. We do not know his name, but he is no longer completely anonymous. This image is now, in some ways, a portrait. The State Library of New South Wales acknowledges this object is part of an important chapter in the Tasmanian story and, though two Boards are in collections in Tasmania (the Tasmanian Museum and Art Gallery, Hobart and the Queen Victoria Museum and Art Gallery, Launceston), each Board is different. The Library holds an important piece of a large and complex puzzle and has a moral obligation to make this information available beyond its metropolitan location. Digitisation, in this case re-digitisation, is allowing for the disruption of this story in sparking new questions around provenance and for the relocating of a Palawa warrior to a more prominent, perhaps even equal role, within a colonial narrative.

In 1829, Robinson was granted a government post in Van Diemen’s Land to ‘conciliate’ with the Palawa peoples. More accurately, Robinson’s core task was dispossession and the systematic disconnection of the Palawa peoples from their Country, community, and culture. Robinson was a habitual diarist and notetaker documenting much of his own life as well as the lives of those around him, including First Nations peoples. His extensive suite of papers represents a familiar and peculiar kind of discomfort for Aboriginal Australians, one in which they are forced to learn about themselves through the eyes and words of their oppressors. For many First Nations peoples of Tasmania, Robinson remains a violent and terrible figure, but his observations of Palawa culture and language are as vital as they are problematic. Importantly, his papers include vibrant and utterly unique descriptions of people, place, flora and fauna, and language, as well as illustrations revealing insights into the routines of daily life (even as those routines were being systematically dismantled by colonial authorities). “Robinson’s records have informed much of the revitalisation of Tasmanian Aboriginal culture in the twentieth century and continue to provide the basis for investigations of identity and deep relationships to land by Aboriginal scholars” (Lehman n.p.). These observations and snippets of lived culture are of immense value to Palawa peoples today but the act of reading between Robinson’s assumptions and beyond his entrenched colonial views is difficult work.Image 3: George Augustus Robinson Papers, 1829–34. Image Credit: Mitchell Library, State Library of New South Wales, A 7023–A 7031.The canonical reference for Robinson’s archive is Friendly Mission: The Tasmanian Journals and Papers of George Augustus Robinson, 1829–1834, edited by N.J.B. Plomley. The volume of over 1,000 pages was first published in 1966. This large-scale project is recognised “as a monumental work of Tasmanian history” (Crane ix). Yet, this standard text (relied upon by Indigenous and non-Indigenous researchers) has clearly not reproduced a significant percentage of Robinson’s Tasmanian manuscripts. Through his presumptuous truncations Plomley has not simply edited Robinson’s work but has, quite literally, written many Palawa stories out of this colonial narrative. It is this lack of agency in determining what should be left out that is most troubling, and reflects an all-too-familiar approach which libraries, including the State Library of New South Wales, are now urgently trying to rectify. Plomley’s preface and introduction does not indicate large tranches of information are missing. Indeed, Plomley specifies “that in extenso [in full] reproduction was necessary” (4) and omissions “have been kept to a minimum” (8). A 32-page supplement was published in 1971. A new edition, including the supplement, some corrections made by Plomley, and some extra material was released in 2008. But much continues to be unknown outside of academic circles, and far too few Palawa Elders and language revival workers have had access to Robinson’s original unfiltered observations. Indeed, Plomley’s text is linear and neat when compared to the often-chaotic writings of Robinson. Digitisation cannot address matters of the materiality of the archive, but such projects do offer opportunities for access to information in its original form, unedited, and unmediated.Extensive consultation with communities in Tasmania is underpinning the digitisation and re-description of a collection which has long been assumed—through partial digitisation, microfilming, and Plomley’s text—to be readily available and wholly understood. Central to this project is not just challenging the canonical status of Plomley’s work but directly challenging the idea non-Aboriginal experts can truly understand the cultural or linguistic context of the information recorded in Robinson’s journals. One of the more exciting outcomes, so far, has been working with Palawa peoples to explore the possibility of Palawa-led transcriptions and translation, and not breaking up the tasks of this work and distributing them to consultants or to non-Indigenous student groups. In this way, people are being meaningfully reunited with their own histories and, crucially, given first right to contextualise and understand these histories. Again, digitisation and disruption can be seen here as allies with the facilitation of accessibility to an archive in ways that re-distribute the traditional power relations around interpreting and telling stories held within colonial-rich collections.Image 4: Detail, George Augustus Robinson Papers, 1829–34. Image Credit: Mitchell Library, State Library of New South Wales, A 7023–A 7031.As has been so brilliantly illustrated by Bruce Pascoe’s recent work Dark Emu (2014), when Aboriginal peoples are given the opportunity to interpret their own culture from the colonial records without interference, they are able to see strength and sophistication rather than victimhood. For, to “understand how the Europeans’ assumptions selectively filtered the information brought to them by the early explorers is to see how we came to have the history of the country we accept today” (4). Far from decrying these early colonial records Aboriginal peoples understand their vital importance in connecting to a culture which was dismantled and destroyed, but importantly it is known that far too much is lost in translation when Aboriginal Australians are not the ones undertaking the translating. ConclusionFor Aboriginal Australians, culture and knowledge is no longer always anchored to Country. These histories, once so firmly connected to communities through their ancestral lands and languages, have been dispersed across the continent and around the world. Many important stories—of family history, language, and ways of life—are held in cultural institutions and understanding the role of responsibly disseminating these collections through digitisation is paramount. In transitioning from physical collections to hybrid collections of the physical and digital, the digitisation processes conducted by memory institutions can be—and due to the size of some collections is inevitably—selective. Limited resources, even for large-scale and well-resourced digitisation projects usually realise outcomes that focus on making visually rich, key, or canonical documents, or those documents considered high use or at risk, available online. Such materials are extracted from a full body of records. Digitisation projects, as noted, tend to be devised for a broader audience where contextual questions are less central to the methodology in favour of presenting notable documents online, separate from their complete collection and, critically, their context. Our institutions carry the weight of past collecting strategies and, today, the pressure of digitisation strategies as well. Contemporary librarians should not be gatekeepers, but rather key holders. In collaborating across sectors and with communities we open doors for education, research, and the repatriation of culture and knowledge. We must, always, remember to open these doors wide: the call of Aboriginal Australians of ‘nothing about us without us’ is not an invitation to collaboration but an imperative. Libraries—as well as galleries, archives, and museums—cannot tell these stories alone. Also, these two case studies highlight what we believe to be one of the biggest mistakes that not just libraries but all cultural institutions are vulnerable to making, the assumption that just because a collection is open access it is also accessible. Digitisation projects are more valuable when communicated, contextualised and—essentially—the result of community consultation. Such work can, for some, be uncomfortable while for others it offers opportunities to embrace disruption and, by extension, opportunities to decolonise collections. For First Nations peoples this work can be more powerful than any simple measurement tool can record. Through examining our past collecting, deliberate efforts to consult, and through digital sharing projects across metropolitan and regional Australia, we can make meaningful differences to the ways in which Aboriginal Australians can, again, own their histories.Acknowledgements The authors acknowledge the Palawa peoples: the traditional custodians of the lands known today as Tasmania.

About half way through Yann Arthus-Bertrand’s film Home (2009) the narrator describes the fall of the Rapa Nui, the indigenous people of the Easter Islands. The narrator posits that the Rapa Nui culture collapsed due to extensive environmental degradation brought about by large-scale deforestation. The Rapa Nui cut down their massive native forests to clear spaces for agriculture, to heat their dwellings, to build canoes and, most importantly, to move their enormous rock sculptures—the Moai. The disappearance of their forests led to island-wide soil erosion and the gradual disappearance of arable land. Caught in the vice of overpopulation but with rapidly dwindling basic resources and no trees to build canoes, they were trapped on the island and watched helplessly as their society fell into disarray. The sequence ends with the narrator’s biting remark: “The real mystery of the Easter Islands is not how its strange statues got there, we know now; it's why the Rapa Nui didn't react in time.” In their unrelenting desire for development, the Rapa Nui appear to have overlooked the role the environment plays in maintaining a society. The island’s Moai accompanying the sequence appear as memento mori, a lesson in the mortality of human cultures brought about by their own misguided and short-sighted practices. Arthus-Bertrand’s Home, a film composed almost entirely of aerial photographs, bears witness to present-day environmental degradation and climate change, constructing society as a fragile structure built upon and sustained by the environment. Home is a call to recognise how contemporary practices of post-industrial societies have come to shape the environment and how they may impact the habitability of Earth in the near future. Through reflexivity and a ritualised structure the text invites spectators to look at themselves in a new light and remake their self-image in the wake of global environmental risk by embracing new, alternative core practices based on balance and interconnectedness. Arthus-Bertrand frames climate change not as a burden, but as a moment of profound realisation of the potential for change and humans ability to create a desirable future through hope and our innate capacity for renewal. This article examines how Arthus-Bertrand’s ritualised construction of climate change aims to remake viewers’ perception of present-day environmental degradation and investigates Home’s place in contemporary climate change communication discourse. Climate change, in its capacity to affect us globally, is considered a world risk. The most recent peer-reviewed Synthesis Report of the Intergovernmental Panel on Climate Change suggests that the concentration of atmospheric greenhouse gases has increased markedly since human industrialisation in the 18th century. Moreover, human activities, such as fossil fuel burning and agricultural practices, are “very likely” responsible for the resulting increase in temperature rise (IPPC 37). The increased global temperatures and the subsequent changing weather patterns have a direct and profound impact on the physical and biological systems of our planet, including shrinking glaciers, melting permafrost, coastal erosion, and changes in species distribution and reproduction patterns (Rosenzweig et al. 353). Studies of global security assert that these physiological changes are expected to increase the likelihood of humanitarian disasters, food and water supply shortages, and competition for resources thus resulting in a destabilisation of global safety (Boston et al. 1–2). Human behaviour and dominant practices of modernity are now on a path to materially impact the future habitability of our home, Earth. In contemporary post-industrial societies, however, climate change remains an elusive, intangible threat. Here, the Arctic-bound species forced to adapt to milder climates or the inhabitants of low-lying Pacific islands seeking refuge in mainland cities are removed from the everyday experience of the controlled and regulated environments of homes, offices, and shopping malls. Diverse research into the mediated and mediatised nature of the environment suggests that rather than from first-hand experiences and observations, the majority of our knowledge concerning the environment now comes from its representation in the mass media (Hamilton 4; Stamm et al. 220; Cox 2). Consequently the threat of climate change is communicated and constructed through the news media, entertainment and lifestyle programming, and various documentaries and fiction films. It is therefore the construction (the representation of the risk in various discourses) that shapes people’s perception and experience of the phenomenon, and ultimately influences behaviour and instigates social response (Beck 213). By drawing on and negotiating society’s dominant discourses, environmental mediation defines spectators’ perceptions of the human-nature relationship and subsequently their roles and responsibilities in the face of environmental risks. Maxwell Boykoff asserts that contemporary modern society’s mediatised representations of environmental degradation and climate change depict the phenomena as external to society’s primary social and economic concerns (449). Julia Corbett argues that this is partly because environmental protection and sustainable behaviour are often at odds with the dominant social paradigms of consumerism, economic growth, and materialism (175). Similarly, Rowan Howard-Williams suggests that most media texts, especially news, do not emphasise the link between social practices, such as consumerist behaviour, and their environmental consequences because they contradict dominant social paradigms (41). The demands contemporary post-industrial societies make on the environment to sustain economic growth, consumer culture, and citizens’ comfortable lives in air-conditioned homes and offices are often left unarticulated. While the media coverage of environmental risks may indeed have contributed to “critical misperceptions, misleading debates, and divergent understandings” (Boykoff 450) climate change possesses innate characteristics that amplify its perception in present-day post-industrial societies as a distant and impersonal threat. Climate change is characterised by temporal and spatial de-localisation. The gradual increase in global temperature and its physical and biological consequences are much less prominent than seasonal changes and hence difficult to observe on human time-scales. Moreover, while research points to the increased probability of extreme climatic events such as droughts, wild fires, and changes in weather patterns (IPCC 48), they take place over a wide range of geographical locations and no single event can be ultimately said to be the result of climate change (Maibach and Roser-Renouf 145). In addition to these observational obstacles, political partisanship, vested interests in the current status quo, and general resistance to profound change all play a part in keeping us one step removed from the phenomenon of climate change. The distant and impersonal nature of climate change coupled with the “uncertainty over consequences, diverse and multiple engaged interests, conflicting knowledge claims, and high stakes” (Lorenzoni et al. 65) often result in repression, rejection, and denial, removing the individual’s responsibility to act. Research suggests that, due to its unique observational obstacles in contemporary post-industrial societies, climate change is considered a psychologically distant event (Pawlik 559), one that is not personally salient due to the “perceived distance and remoteness [...] from one’s everyday experience” (O’Neill and Nicholson-Cole 370). In an examination of the barriers to behaviour change in the face of psychologically distant events, Robert Gifford argues that changing individuals’ perceptions of the issue-domain is one of the challenges of countering environmental inertia—the lack of initiative for environmentally sustainable social action (5). To challenge the status quo a radically different construction of the environment and the human-nature relationship is required to transform our perception of global environmental risks and ultimately result in environmentally consequential social action. Yann Arthus-Bertrand’s Home is a ritualised construction of contemporary environmental degradation and climate change which takes spectators on a rite of passage to a newfound understanding of the human-nature relationship. Transformation through re-imagining individuals’ roles, responsibilities, and practices is an intrinsic quality of rituals. A ritual charts a subjects path from one state of consciousness to the next, resulting in a meaningful change of attitudes (Deflem 8). Through a lifelong study of African rituals British cultural ethnographer Victor Turner refined his concept of rituals in a modern social context. Turner observed that rituals conform to a three-phased processural form (The Ritual Process 13–14). First, in the separation stage, the subjects are selected and removed from their fixed position in the social structure. Second, they enter an in-between and ambiguous liminal stage, characterised by a “partial or complete separation of the subject from everyday existence” (Deflem 8). Finally, imbued with a new perspective of the outside world borne out of the experience of reflexivity, liminality, and a cathartic cleansing, subjects are reintegrated into the social reality in a new, stable state. The three distinct stages make the ritual an emotionally charged, highly personal experience that “demarcates the passage from one phase to another in the individual’s life-cycle” (Turner, “Symbols” 488) and actively shapes human attitudes and behaviour. Adhering to the three-staged processural form of the ritual, Arthus-Bertrand guides spectators towards a newfound understanding of their roles and responsibilities in creating a desirable future. In the first stage—the separation—aerial photography of Home alienates viewers from their anthropocentric perspectives of the outside world. This establishes Earth as a body, and unearths spectators’ guilt and shame in relation to contemporary world risks. Aerial photography strips landscapes of their conventional qualities of horizon, scale, and human reference. As fine art photographer Emmet Gowin observes, “when one really sees an awesome, vast place, our sense of wholeness is reorganised [...] and the body seems always to diminish” (qtd. in Reynolds 4). Confronted with a seemingly infinite sublime landscape from above, the spectator’s “body diminishes” as they witness Earth’s body gradually taking shape. Home’s rushing rivers of Indonesia are akin to blood flowing through the veins and the Siberian permafrost seems like the texture of skin in extreme close-up. Arthus-Bertrand establishes a geocentric embodiment to force spectators to perceive and experience the environmental degradation brought about by the dominant social practices of contemporary post-industrial modernity. The film-maker visualises the maltreatment of the environment through suggested abuse of the Earth’s body. Images of industrial agricultural practices in the United States appear to leave scratches and scars on the landscape, and as a ship crosses the Arctic ice sheets of the Northwest Passage the boat glides like the surgeon’s knife cutting through the uppermost layer of the skin. But the deep blue water that’s revealed in the wake of the craft suggests a flesh and body now devoid of life, a suffering Earth in the wake of global climatic change. Arthus-Bertrand’s images become the sublime evidence of human intervention in the environment and the reflection of present-day industrialisation materially altering the face of Earth. The film-maker exploits spectators’ geocentric perspective and sensibility to prompt reflexivity, provide revelations about the self, and unearth the forgotten shame and guilt in having inadvertently caused excessive environmental degradation. Following the sequences establishing Earth as the body of the text Arthus-Bertrand returns spectators to their everyday “natural” environment—the city. Having witnessed and endured the pain and suffering of Earth, spectators now gaze at the skyscrapers standing bold and tall in the cityscape with disillusionment. The pinnacles of modern urban development become symbols of arrogance and exploitation: structures forced upon the landscape. Moreover, the images of contemporary cityscapes in Home serve as triggers for ritual reflexivity, allowing the spectator to “perceive the self [...] as a distanced ‘other’ and hence achieve a partial ‘self-transcendence’” (Beck, Comments 491). Arthus-Bertrand’s aerial photographs of Los Angeles, New York, and Tokyo fold these distinct urban environments into one uniform fusion of glass, metal, and concrete devoid of life. The uniformity of these cultural landscapes prompts spectators to add the missing element: the human. Suddenly, the homes and offices of desolate cityscapes are populated by none other than us, looking at ourselves from a unique vantage point. The geocentric sensibility the film-maker invoked with the images of the suffering Earth now prompt a revelation about the self as spectators see their everyday urban environments in a new light. Their homes and offices become blemishes on the face of the Earth: its inhabitants, including the spectators themselves, complicit in the excessive mistreatment of the planet. The second stage of the ritual allows Arthus-Bertrand to challenge dominant social paradigms of present day post-industrial societies and introduce new, alternative moral directives to govern our habits and attitudes. Following the separation, ritual subjects enter an in-between, threshold stage, one unencumbered by the spatial, temporal, and social boundaries of everyday existence. Turner posits that a subjects passage through this liminal stage is necessary to attain psychic maturation and successful transition to a new, stable state at the end of the ritual (The Ritual Process 97). While this “betwixt and between” (Turner, The Ritual Process 95) state may be a fleeting moment of transition, it makes for a “lived experience [that] transforms human beings cognitively, emotionally, and morally.” (Horvath et al. 3) Through a change of perceptions liminality paves the way toward meaningful social action. Home places spectators in a state of liminality to contrast geocentric and anthropocentric views. Arthus-Bertrand contrasts natural and human-made environments in terms of diversity. The narrator’s description of the “miracle of life” is followed by images of trees seemingly defying gravity, snow-covered summits among mountain ranges, and a whale in the ocean. Grandeur and variety appear to be inherent qualities of biodiversity on Earth, qualities contrasted with images of the endless, uniform rectangular greenhouses of Almeria, Spain. This contrast emphasises the loss of variety in human achievements and the monotony mass-production brings to the landscape. With the image of a fire burning atop a factory chimney, Arthus-Bertrand critiques the change of pace and distortion of time inherent in anthropocentric views, and specifically in contemporary modernity. Here, the flames appear to instantly eat away at resources that have taken millions of years to form, bringing anthropocentric and geocentric temporality into sharp contrast. A sequence showing a night time metropolis underscores this distinction. The glittering cityscape is lit by hundreds of lights in skyscrapers in an effort, it appears, to mimic and surpass daylight and thus upturn the natural rhythm of life. As the narrator remarks, in our present-day environments, “days are now the pale reflections of nights.” Arthus-Bertrand also uses ritual liminality to mark the present as a transitory, threshold moment in human civilisation. The film-maker contrasts the spectre of our past with possible visions of the future to mark the moment of now as a time when humanity is on the threshold of two distinct states of mind. The narrator’s descriptions of contemporary post-industrial society’s reliance on non-renewable resources and lack of environmentally sustainable agricultural practices condemn the past and warn viewers of the consequences of continuing such practices into the future. Exploring the liminal present Arthus-Bertrand proposes distinctive futurescapes for humankind. On the one hand, the narrator’s description of California’s “concentration camp style cattle farming” suggests that humankind will live in a future that feeds from the past, falling back on frames of horrors and past mistakes. On the other hand, the example of Costa Rica, a nation that abolished its military and dedicated the budget to environmental conservation, is recognition of our ability to re-imagine our future in the face of global risk. Home introduces myths to imbue liminality with the alternative dominant social paradigm of ecology. By calling upon deep-seated structures myths “touch the heart of society’s emotional, spiritual and intellectual consciousness” (Killingsworth and Palmer 176) and help us understand and come to terms with complex social, economic, and scientific phenomena. With the capacity to “pattern thought, beliefs and practices,” (Maier 166) myths are ideal tools in communicating ritual liminality and challenging contemporary post-industrial society’s dominant social paradigms. The opening sequence of Home, where the crescent Earth is slowly revealed in the darkness of space, is an allusion to creation: the genesis myth. Accompanied only by a gentle hum our home emerges in brilliant blue, white, and green-brown encompassing most of the screen. It is as if darkness and chaos disintegrated and order, life, and the elements were created right before our eyes. Akin to the Earthrise image taken by the astronauts of Apollo 8, Home’s opening sequence underscores the notion that our home is a unique spot in the blackness of space and is defined and circumscribed by the elements. With the opening sequence Arthus-Bertrand wishes to impart the message of interdependence and reliance on elements—core concepts of ecology. Balance, another key theme in ecology, is introduced with an allusion to the Icarus myth in a sequence depicting Dubai. The story of Icarus’s fall from the sky after flying too close to the sun is a symbolic retelling of hubris—a violent pride and arrogance punishable by nemesis—destruction, which ultimately restores balance by forcing the individual back within the limits transgressed (Littleton 712). In Arthus-Bertrand’s portrayal of Dubai, the camera slowly tilts upwards on the Burj Khalifa tower, the tallest human-made structure ever built. The construction works on the tower explicitly frame humans against the bright blue sky in their attempt to reach ever further, transgressing their limitations much like the ill-fated Icarus. Arthus-Bertrand warns that contemporary modernity does not strive for balance or moderation, and with climate change we may have brought our nemesis upon ourselves. By suggesting new dominant paradigms and providing a critique of current maxims, Home’s retelling of myths ultimately sees spectators through to the final stage of the ritual. The last phase in the rite of passage “celebrates and commemorates transcendent powers,” (Deflem 8) marking subjects’ rebirth to a new status and distinctive perception of the outside world. It is at this stage that Arthus-Bertrand resolves the emotional distress uncovered in the separation phase. The film-maker uses humanity’s innate capacity for creation and renewal as a cathartic cleansing aimed at reconciling spectators’ guilt and shame in having inadvertently exacerbated global environmental degradation. Arthus-Bertrand identifies renewable resources as the key to redeeming technology, human intervention in the landscape, and finally humanity itself. Until now, the film-maker pictured modernity and technology, evidenced in his portrayal of Dubai, as synonymous with excess and disrespect for the interconnectedness and balance of elements on Earth. The final sequence shows a very different face of technology. Here, we see a mechanical sea-snake generating electricity by riding the waves off the coast of Scotland and solar panels turning towards the sun in the Sahara desert. Technology’s redemption is evidenced in its ability to imitate nature—a move towards geocentric consciousness (a lesson learned from the ritual’s liminal stage). Moreover, these human-made structures, unlike the skyscrapers earlier in the film, appear a lot less invasive in the landscape and speak of moderation and union with nature. With the above examples Arthus-Bertrand suggests that humanity can shed the greed that drove it to dig deeper and deeper into the Earth to acquire non-renewable resources such as oil and coal, what the narrator describes as “treasures buried deep.” The incorporation of principles of ecology, such as balance and interconnectedness, into humanity’s behaviour ushers in reconciliation and ritual cleansing in Home. Following the description of the move toward renewable resources, the narrator reveals that “worldwide four children out of five attend school, never has learning been given to so many human beings” marking education, innovation, and creativity as the true inexhaustible resources on Earth. Lastly, the description of Antarctica in Home is the essence of Arthus-Bertrand’s argument for our innate capacity to create, not simply exploit and destroy. Here, the narrator describes the continent as possessing “immense natural resources that no country can claim for itself, a natural reserve devoted to peace and science, a treaty signed by 49 nations has made it a treasure shared by all humanity.” Innovation appears to fuel humankind’s transcendence to a state where it is capable of compassion, unification, sharing, and finally creating treasures. With these examples Arthus-Bertrand suggests that humanity has an innate capacity for creative energy that awaits authentic expression and can turn humankind from destroyer to creator. In recent years various risk communication texts have explicitly addressed climate change, endeavouring to instigate environmentally consequential social action. Home breaks discursive ground among them through its ritualistic construction which seeks to transform spectators’ perception, and in turn roles and responsibilities, in the face of global environmental risks. Unlike recent climate change media texts such as An Inconvenient Truth (2006), The 11th Hour (2007), The Age of Stupid (2009), Carbon Nation (2010) and Earth: The Operator’s Manual (2011), Home eludes simple genre classification. On the threshold of photography and film, documentary and fiction, Arthus-Bertrand’s work is best classified as an advocacy film promoting public debate and engagement with a universal concern—the state of the environment. The film’s website, available in multiple languages, contains educational material, resources to organise public screenings, and a link to GoodPlanet.info: a website dedicated to environmentalism, including legal tools and initiatives to take action. The film-maker’s approach to using Home as a basis for education and raising awareness corresponds to Antonio Lopez’s critique of contemporary mass-media communications of global risks. Lopez rebukes traditional forms of mediatised communication that place emphasis on the imparting of knowledge and instead calls for a participatory, discussion-driven, organic media approach, akin to a communion or a ritual (106). Moreover, while texts often place a great emphasis on the messenger, for instance Al Gore in An Inconvenient Truth, Leonardo DiCaprio in The 11th Hour, or geologist Dr. Richard Alley in Earth: The Operator’s Manual, Home’s messenger remains unseen—the narrator is only identified at the very end of the film among the credits. The film-maker’s decision to forego a central human character helps dissociate the message from the personality of the messenger which aids in establishing and maintaining the geocentric sensibility of the text. Finally, the ritual’s invocation and cathartic cleansing of emotional distress enables Home to at once acknowledge our environmentally destructive past habits and point to a hopeful, environmentally sustainable future. While The Age of Stupid mostly focuses on humanity’s present and past failures to respond to an imminent environmental catastrophe, Carbon Nation, with the tagline “A climate change solutions movie that doesn’t even care if you believe in climate change,” only explores the potential future business opportunities in turning towards renewable resources and environmentally sustainable practices. The three-phased processural form of the ritual allows for a balance of backward and forward-looking, establishing the possibility of change and renewal in the face of world risk. The ritual is a transformative experience. As Turner states, rituals “interrupt the flow of social life and force a group to take cognizance of its behaviour in relation to its own values, and even question at times the value of those values” (“Dramatic Ritual” 82). Home, a ritualised media text, is an invitation to look at our world, its dominant social paradigms, and the key element within that world—ourselves—with new eyes. It makes explicit contemporary post-industrial society’s dependence on the environment, highlights our impact on Earth, and reveals our complicity in bringing about a contemporary world risk. The ritual structure and the self-reflexivity allow Arthus-Bertrand to transform climate change into a personally salient issue. This bestows upon the spectator the responsibility to act and to reconcile the spectre of the past with the vision of the future.Acknowledgments The author would like to thank Dr. Angi Buettner whose support, guidance, and supervision has been invaluable in preparing this article.

Thermal and flow diagnostics of power units makes use of diagnostic relations i.e. relations between fault signatures (sets of symptoms) and geometry degradation of its components. Determining symptoms may base on thorough thermal measurements of the cycle. However, numerous apparatuses in the cycle are not or cannot be properly equipped for necessary measurements. Examples of such apparatuses in a steam turbine are external glands and nozzle box sealings. The paper studies the applicability of a selected type of Artificial Neural Network, ANN, as a diagnostic relation for locating faulty apparatuses in HP and IP turbine casings, including their sealing systems. The obtained results can be assessed as good for single faults, and satisfactory for multiple faults of the cycle components. The examined type of ANN can be used e.g. in a modular hierarchical diagnostic system proposed by Gluch & Krzyzanowski, 1998, 1999.

In gas turbine operation, engine performance and health status is very important information for engine operators. Such engine performance is normally represented by engine air flow rate, compressor pressure ratios, compressor isentropic efficiencies, turbine entry temperature, turbine isentropic efficiencies, etc. while the engine health status is represented by compressor and turbine efficiency indices and flow capacity indices, etc. However, these crucial performance and health information can not be directly measured and therefore are not easily available. In this research, a novel Adaptive Gas Path Analysis (Adaptive GPA) approach has been developed to estimate actual engine performance and gas path component health status by using gas path measurements, such as gas path pressures, temperatures, shaft rotational speeds, fuel flow rate, etc. Two steps are included in the Adaptive GPA approach, the first step is the estimation of degraded engine performance status by a novel application of a performance adaptation method and the second step is the estimation of engine health status at component level by using a new diagnostic method introduced in this paper based on the information obtained in the first step. The developed Adaptive GPA approach has been tested in four test cases where the performance and degradation of a model gas turbine engine similar to Rolls-Royce aero engine AVON-300 have been analyzed. The case studies have shown that the developed novel linear and non-linear Adaptive GPA approach can accurately and quickly estimate the degraded engine performance and predict the degradation of major engine gas path components with the existence of measurement noise. The test cases have also shown that the calculation time required by the approach is short enough for its potential online applications.
