Abstract and Figures

The Anthropocene, a term launched into public debate by Nobel Prize winner Paul Crutzen, has been used informally to describe the time period during which human actions have had a drastic effect on the Earth and its ecosystems. This book presents evidence for defining the Anthropocene as a geological epoch, written by the high-profile international team analysing its potential addition to the geological time scale. The evidence ranges from chemical signals arising from pollution, to landscape changes associated with urbanisation, and biological changes associated with species invasion and extinctions. Global environmental change is placed within the context of planetary processes and deep geological time, allowing the reader to appreciate the scale of human-driven change and compare the global transition taking place today with major transitions in Earth history. This is an authoritative review of the Anthropocene for graduate students and academic researchers across scientific, social science and humanities disciplines.

Studying the dynamic changes in the coastline of the northeastern Caspian Sea is significant since the level of the Caspian is unstable, and the coastline change can cause enormous damage to the ecology, economy, and population of the coastal part of Kazakhstan. In this work, we use remote sensing and Geographic Information System (GIS) technologies to study the changes in the coastline of the northeastern Caspian Sea and predict the extent of flooding with increasing water levels. The proposed methodology for creating dynamic maps can be used to monitor the coastline and forecast the extent of flooding in the area. As a result of this work, the main factors affecting changes in the coastline were identified. After analyzing the water level data from 1988 to 2019, it was revealed that the rise in water level was observed from 1980 to 1995. The maximum sea level rise was recorded at −26.04 m. After that, the sea level began to fall, and between 1996 and 2009, there were no significant changes; the water level fluctuated with an average of −27.18 m. Then, a map of the water level dynamics in the Caspian Sea from 1988 to 2019 was compiled. According to the dynamics map, water level rise and significant coastal retreat were revealed, especially in the northern part of the Caspian Sea and the northern and southern parts of Sora Kaydak. The method for predicting the estimated flooding area was described. As a result, based on a single map, the flooding area of the northeast coast was predicted. A comparative analysis of Landsat and SRTM data is presented.
... (Álvarez, 2020) Este ejemplo de colapso ambiental a causa de la actividad humana, puede darnos indicios de que estamos entrando en un nuevo tiempo geológico acuñado por Paul Crutzen y Eugene Stoermer (2000) como Antropoceno. El autor considera que la acción del comportamiento humano sobre la Tierra en los últimos años, ha constituido una nueva era geológica provocando cambios en el ciclo del agua, desequilibrios, destrucción en los ecosistemas marinos y terrestres, aumento de fenómenos meteorológicos extremos, acidificación de los océanos, desaparición de los bosques etc. Zalasiewicz menciona también, que los cambios en los ciclos del carbono, el nitrógeno o el fósforo provocados por el uso de pesticidas, tendrán repercusiones en la composición de los estratos terrestres (Zalasiewicz, 2019). El tiempo es un elemento central en la conceptualización del Antropoceno, nos conduce a considerar una temporalidad biológica y geológica en un mundo que se mueve dentro de un presente estrecho (Trischler, 2017). ...

Based on Ehrenfried Pfeiffer's method of sensitive crystallization, the Cartographies of Metamorphosis artistic project exposes the vitality, in the form of mandala graphics, of the different horticultural products from Campo de Cartagena, a method that makes the intrinsic quality of the material visible organic. In 2016, the Mar Menor landscape collapsed for the first time and accentuated its state of environmental crisis, due in part to the dumping of large amounts of organic matter and nutrients of various kinds, but especially from agricultural and livestock activities. Made in the context of the environmental crisis of the Mar Menor, the sculptural and audiovisual installation metaphorically reflects on the new geological era coined by Paul Crutzen and the eutrophication landscape around the lagoon.
... It englobes the scientific concept of the 'anthropogenic biome' (Ellis et al. 2016;Fuentes 2017), respectively, 'social-ecological system', see for example (Colding and Barthel 2019). Associating the notions 'human niche' and 'Earth System' as synonymous acknowledges the Anthropocene as factual, regardless of whether being included in the geological time scale (Zalasiewicz et al. 2019). Nevertheless, the notions 'human niche' and 'Earth System' apply contextually; the notion 'Earth System' is process-oriented, and 'human niche' is holistic. ...

Link: https://rdcu.be/cyt9h The impacts of anthropogenic change do call for strengthening the socio-political and socio-economic anchorage of geoethical thinking. Geosciences are more than mere techno-scientific disciplines as, for example, geohydrology shows. Geoscience expertise ties geosciences and people's social lives. Geosciences are relevant for the societies' functioning, namely, to operate a technosphere at local, regional and planetary scales. Therefore, geoscience expertise includes a school of philosophical thinking called geoethics. Although initially designed for professional use, geoethics should support any citizen’s individual, professional and civic deal-ings. Nowadays, the technosphere is a vital feature of the contemporary Earth System (or ‘human niche’). In these contexts, conceptual benchmarks for geoethical thinking are described to address: i) the operational limits of aspirational stipulations and ii) a stronger socio-political anchorage of geoethical thinking. Methodo-logically, the present study relates geoethical thinking with the political philosophies of Bunge, Jonas and Kohlberg about people's social lives. Their works offer foundations for a broad application of geoethical thinking by providing benchmarks: Kohlberg's ‘hierarchy of societal coordination (moral adequacy)’, Bunge’s ‘balance of individual happiness (well-being) and duty’ and Jonas' ‘imperative of responsibility for agents of change’. These political philosophies can be combined with geoethical thinking (or geoethics). A ‘geo-ethical logic’ can be formulated, calling to act with: agent-centricity, virtue-focus, responsible-focus, re-producible/scientific knowledge, all-agent-inclusiveness and universal-rights-base. Whilst preserving the de-sign of geoethics, the proposed geo-ethical logic strengthens the socio-political anchorage of geoethical think-ing, and aspirational stipulations are benchmarked. Further study should aim to complement the given frame of socio-political benchmarks by socio-economic benchmarking. (published by Sustainable Water Resources Management; https://rdcu.be/cyt9h)
... As far as geoscientists are concerned, acknowledging that the Holocene is over (Waters et al., 2016) also means recognizing that human pandemics have reached geological records (Zalasiewicz et al., 2019). Thus, the naming of the Anthropocene seems to make sense today. ...

This paper examines the responsibilities that geoscientists have because of the body of expertise they can offer; including geoethical practices. The COVID_19 health pandemic of the early 2020s provides a reinforcing lens for this perspective. The COVID_19 health pandemic illustrates the essence of any Anthropocene, namely being less a geological epoch than a future world of (much) more than 7 billion people and their social and economic practices of a planetary reach. Human beings operate a planetary technosphere to safeguard their living and well-being. This ability is the origin of any kind of Anthropocene. The role of geoscientific expertise must be analyzed in this context. The inference is that geoscientific expertise made the Anthropocene possible. Geoscientific knowledge is embedded in the societal corpus of technologies, cultures and insights. People need geoscientific knowledge to evaluate anthropogenic global changes in their social context; even as a consumer of resources. Citizens need insight into how the Earth system works to make informed decisions. Therefore, geoscientific knowledge has the potential to shape anthropogenic global change. As a result, the social responsibility of geoscientists is of foremost importance. A well-thought-out guide is needed on how this responsibility can be assumed in a very diverse world. The search for such a guide is the core of geoethics. This essay contributes to this search. Submitted to: "Geographies of the Anthropocene" (in review)
... Turning to the geoscientists, recognising that the Holocene has ended (Waters et al. 2016) is acknowledging that the pandemics reached the geological record (Zalasiewicz et al. 2019). Hence, as debated since two decades renaming the current times 'Anthropocene' seems valid (Bohle and Bilham 2019); 'Pandemocene' may be an alternative. ...

This text explores the societal context of geosciences including geoethics in relation to the concept of pandemics. Geosciences are instrumental in making anthropogenic global change happen, that making it a Pandemic. Therefore, geoscientists are its co-architects who should assume the responsibility that comes with their role as agents of technology-driven change. In this context, how geoscientists use their expertise is not an impartial matter. They are called to duty to offer cures in the Pandemocene; that is the essence of geoethics. This text draws on two upcoming conferences contributions (“Taking responsibility: Geo-societal studies of alternative futures,” EGU2020, Vienna, with Martin Kowarsch, MCC; “Geoethics for Operating in the Human Niche” GGM’20, Porto, inspired by E. Marone), a paper published in 2019 (“The ‘Anthropocene Proposal’: A Possible Quandary and A Work-Around” with N. Bilham, https://www.mdpi.com/2571-550X/2/2/19) and a blog post prepared for the Salzburg Global Seminar #593 (2017)

Jaan Kaplinski kireva loomingu kese on ökoloogiline mõtlemine. Nii tema luule, proosa, esseistika kui ka laiemalt eluhoiak põhineb dünaamilise tasakaalu otsimisel inimese ja looduse vahel. Põhiküsimus, millega ta oma loometöös tegeleb, on küsimus elu järele – kuidas elu mõista, kuidas tagada elu mitmekesisus ja jätkumine ning kuidas saavutada mõtestatud elu. Artikkel esitab visandi Kaplinski ökoloogilisest mõtlemisest, tuginedes peamiselt tema esseedele. Fookuses on küsimus, mida on Kaplinskil öelda meile praegu, keset süvenevat keskkonnakriisi: mida me saame õppida tema tekstidest eluks – ellujäämiseks – antropotseenis. --- Ecological thinking lies at the core of Jaan Kaplinski’s (1941–2021) diverse catalogue. His poetry, prose and essays were grounded in the quest to achieve a dynamic balance between humans and nature. Life was Kaplinski’s primary focus: how it can be understood, how to ensure its continuity, and how to attain a meaningful existence. Today, Kaplinski’s ecological writing has acquired new relevance. An ever-keener awareness of human responsibility for the environmental crisis, the declaration of a new geological era (the Anthropocene), and a re-evaluation of the relationship between nature and culture give us an opportunity to read Kaplinski from a fresh perspective. Kaplinski’s ecological worldview essentially boils down to three principles. The first of these is holism. As Kaplinski saw it, life forms a complete network in which everything is interconnected and interdependent. The clearest expression of this belief appeared in his 2000 travelogue Spring on Two Coasts, or A Sentimental Journey to America: “In fact, Life on Earth is not a chain, but a web, a network. If a knot or an eyelet breaks then it is still a web, albeit broken. Earth’s biosphere is currently a broken web, one so vital to us all. It is broken, but still working.” (Kaplinski 2000, 25) Secondly, there is the principle of anti-economism. Life cannot be subjected to economic thinking, which tends to view people as creators of value, and thus believe that more work equals more value. Economic thinking leads to environmental destruction and devastation. Ecology is uneconomic. Kaplinski wrote his main essay on this topic, titled: “Ecology and Economy”, in 1972. Thirdly, there is the principle of pluralism. In much of his writing, Kaplinski emphasised that reducing nature’s diversity weakens its self-regulating mechanisms. As a member of a tiny nation, he expressed equal appreciation for natural and cultural diversity, writing in 1972: “The biosphere is very strange and our cautious existence in it can be summarised with the slogan ‘reverence for information’. For not one genotype, community, language, or culture can be restored if they should disappear.” (Kaplinski [1972] 1996, 71) Kaplinski’s perception of today’s global ecological situation was highly pessimistic. The preservation of natural diversity was one of his greatest concerns, as he was convinced that humankind is taking more from the environment than can be restored through its renewal. Humanity has become a force of natural destruction, which simultaneously means self-destruction. Pessimistic diagnoses of the state of the world are abundant, to say the least. However, the value of Kaplinski’s writing for the modern readerfirst and foremost lies in his proposals for how to emerge from the crisis. In the interests of symmetry, one can select three items from his extensive catalogue. Firstly, a shift in thinking and in imagination is required. According to Kaplinski, improving the ecological situation starts with a change in thought, by replacing economic thinking with ecological thinking. Life-endangering dreams must be replaced with ones that can cause no harm: “There are two possible courses of action: either we slow the economic engine, refrain from accelerating, and leave most of our dreams unfulfilled, or we change the dreams themselves and dream only of what isn’t dangerous to achieve.” (Kaplinski [1972] 1996, 69) Secondly, the new self-regulation of mankind is mentioned. Kaplinski believes that it is possible to alter the relationships between humans and nature by consciously adjusting our behaviour. In his 1973 essay “Thoughts on Ecosystems and Human Culture”, he suggested that the history of human development seems to prove that we once possessed an ability to self-regulate, similar to that of other species: “If the stability of the ecosystem hinges greatly upon human activity, then man has, in principle, the opportunity to preserve or even restore stability by steering that ecosystem via his own actions. Man can govern nature by governing himself.” (Kaplinski [1973] 2004, 54) Thirdly, and most importantly, humankind as a whole can learn how to think ecologically and consciously regulate our behaviour based on the experiences of peoples that exist within nature. Kaplinski’s ecological worldview has strong roots in anthropology and one of his primary long-term interests was searching for ties between religion and ecological thinking. In sum, Kaplinski’s message to today’s world is this: humanity’s sole chance to survive in the Anthropocene is to learn to consider all living beings as an interconnected web, to exist in a way that disturbs as few other living beings as possible, and to seek an optimal balance between our needs and the environment’s possibilities. This will require a tremendous revolution of human thought; a cultural shift that places our attitude towards nature on new foundations that lie beyond simplistic contrasts such as culture vs. nature and humans vs. animals.

Die Geowissenschaften befassen sich mit der Entstehung, Entwicklung und Funktionsweise des Systems Erde, insbesondere auch den Inter-aktionen zwischen der festen Erde und der Biosphäre. Hydrosphäre und Atmo-sphäre waren in der Erdvergangenheit deutlich anders beschaffen als heute, lebensfreundliche Bedingungen existieren aber seit mindestens vier Milliarden Jahren und das Leben selbst spielte eine aktive Rolle bei der Gestaltung der Umwelt. In diesem Kapitel wird das Thema Umwelt aus geowissenschaftlicher Sicht vorgestellt. Zunächst wird die Disziplin „Geowissenschaften“ als Fachwissenschaft mit ihren Unterdisziplinen und ihrer spezifischen geschichtlichen Entwicklung präsentiert. An verschiedenen Thematiken wie z. B. der Entstehung und stoffli-chen Entwicklung der Erde, ihrer vulkanischen und seismischen Aktivität und der damit verbundenen Umweltgefahren sowie der biogeochemischen Stoffkreisläufe, die durch den Menschen stark beeinflusst werden, sollen beispielhaft wichtige umweltspezifische Fragestellungen in den Geowissenschaften verdeutlicht werden. Zudem werden Verknüpfungen und enge Bezüge zu anderen disziplinären Kapi-teln wie z. B. →Rechtswissenschaften, →Chemie, →Geographie und →Physik sowie zu den interdisziplinären Kapiteln →Anthropozän, →Evolution, →Klimawandel, →Risiken, →Wachstum und →Raum aufgezeigt.
