Rock Strata

The purest of science fiction. The Earth, in a post-human future, many millions of years hence, being re-explored. By . . . whom? Perhaps extraterrestrial explorers or colonists, just as we now peer at images of rock strata sent back by the Mars landers. Or perhaps a new, home-grown intelligence: say, a newly evolved species of hyper-intelligent rodent. No matter. What would such explorers, of whatever ancestry, find of our own, long-vanished, human empire? A frivolous question, perhaps. But perhaps not. It is hard, as humans, to get a proper perspective on the human race. We know that the Earth has a history that is long beyond human imagination, and that our own history is tiny by comparison. We know that we are animals, and yet we have transcended our natural environment to live in surroundings that, mostly, we have manufactured for ourselves. We know that this created environment is evolving at a speed that is vastly more rapid than the normal evolution of biological organisms or communities. We do not understand, quite, how our created environment and our activities interact with the natural environment, and we do not know what the long-term consequences will be. Let us take one view. We are simply one species out of perhaps 30 million currently inhabiting the planet (reputable estimates range from some 5 million to over 100 million). We are briefly in the golden age of our power, our dominance. But we are destined to extinction also, just as the dinosaurs became extinct. The world will then go on as before. Once a geological age or two has passed, there will be nothing but the odd bone or gold ring to show that we were ever here. In this scenario, comparison with the dinosaurs is apt. They were the top predators of their day, as our single species is now. But consider, also, the differences between us and the dinosaurs. The dinosaurs existed on this Earth for about a hundred million years, and included many species adapted to different environments. Homo sapiens is but one species, and has been around for less than a quarter of a million years, less than a tenth of an average species’ longevity.

Cultural Construct

To view culture as a multispecies and not as an anthropocentric one is the call of the era. The liberal Humanist idea of human as an autonomous entity is to be debunked, as culture involves not only Homo sapiens, but also other species – animals, plants, microbes, machines and hybrids. No species can dwell independently. Each species thrives in a network, interconnected and interdependent to each other. This network forms a culture of multispecies, where every being is akin to the other. Multispecies culture is all inclusive and all encompassing, disregarding the crippling binaries of human/ non-human, culture/nature, abled/disabled, normal/abnormal and so on. It is important to realize that each binary is an anthropocentric cultural construct. It must be discarded in order to create the culture of companion species, that is includes all forms of existence, not overlooking the ‘unwanted’ object as the minor ‘other’, in the anthropocentric view. The paper aims to argue that each species (highlighting the figure of tree in the paper) is an active actor in the bio cultural space. It strives to emancipate the figure of a tree from the clutch of anthropocentric notion, as ‘nature’/ ‘passive recipient’/ ‘care-giver’/ ‘mother’. To serve my purpose, I have chosen a Science Fiction, titled The Saliva Tree by Brian Aldiss. The fiction has an alien tree, functioning in a farm on the Earth. The tree has a horrendous physical appearance, is carnivorous and is non-sessile. All such features compile to render the arboreal creature as a ‘monster’, an identity imposed upon a misfit, considering it as a threat to the human-centered culture. I have argued how the farm with the ‘monster’ tree and other variety of species and machines becomes an archive, a dynamic biocultural space. It also enhances the botanical culture or ‘FloraCulture’, as termed by John Charles Ryan.

"Die Hypothese eines neuen Erdzeitalters, des »Anthropozän«, wird seit ihrer Postulierung durch den Chemiker und Nobelpreisträger Paul Crutzen im Jahr 2000 intensiv diskutiert. Der Beginn des Anthropozän wird zumeist um 1800 datiert und in einen Zusammenhang mit der Industrialisierung gestellt. Seither, so die These, ist die Menschheit zu einer quasi geologischen Kraft und sind menschliche Infrastrukturen zum wichtigsten Einflussfaktor auf die biologischen, geologischen und atmosphärischen Prozesse auf der Erde geworden. Christian Schwägerl und Reinhold Leinfelder führen in ihrem Beitrag Argumente und Beispiele für die langfristigen Veränderungen und für die »Reorganisation des gesamten Erdsystems« an, welche die These vom Anthropozän und der »menschgemachten« Erde stützen. In ihrem Beitrag widersprechen sie dem vorschnellen Eindruck, es handle sich bei der Idee einer neuen geologischen Erdepoche nur um einen neuen Sammelbegriff für all das, was als Umweltproblem gilt. Vielmehr betonen die Autoren auch das Potential des Menschen und seiner Technologien zur positiven Gestaltung seines Lebensraums und zur Transformation der Erde. Sie verstehen das Anthropozän nicht nur als rein physische Zustandsbeschreibung, sondern auch als gesellschaftliche Herausforderung und als Forschungsauftrag. Niels Werber setzt in seinem Beitrag an der Frage der notorischen Epochenbildung um 1800 an und kritisiert, dass der Anthropozän-Diskurs sich allein auf die vermeintliche Evidenz naturwissenschaftlicher, vor allem geologischer Daten und Zahlen verlassen würde und ausgerechnet für die Plausibilisierung des Zeitalters des Menschen Kenntnisse über den Menschen, seine Sozialordnung und Kultur offenbar nicht nötig seien. Stattdessen fordert Werber im Anschluss an Niklas Luhmann dazu auf, die Anthropozän-Hypothese als einen Beitrag zur »Selbstbeschreibung der Gesellschaft«, das heißt zur Beschreibung der Einfügung des Menschen und seiner Gesellschaft in die Welt zu verstehen. </br></br> The hypothesis of a new geological era, the »Anthropocene«, is discussed intensively since its presentation by the chemist and Nobel Prize winner Paul Crutzen in 2000. The beginning of the Anthropocene is usually dated to 1800 and put into the context of the industrialization. Since then, according to Crutzen, mankind has become a quasi-geological force and human infrastructures have developed into a primary influence on the biological, geological and atmospheric processes on Earth. In their contribution, Christian Schwägerl and Reinhold Leinfelder present examples of the long-term changes and arguments for the »reorganization of the entire Earth system«, supporting the thesis of the Anthropocene and the »man-made« Earth. In their article they contradict the premature impression that the Anthropocene is nothing but a new umbrella term for everything that is considered an environmental problem. Rather, the authors emphasize the potential of man and his technologies for the positive design of his habitat and the transformation of the earth. They understand the Anthropocene not only as a description of a purely physical state, but also as a social and scientific challenge. Niels Werber puts in his contribution the notorious epoch threshold 1800 in question. Furthermore, he criticizes that the discourse of the Anthropocene relies solely on the supposed evidence of science, especially of geological data and figures, and thus neglects in its effort to describe a »geological age of mankind« precisely the emerging knowledge of man, social order and culture. Instead, Werber understands the »Anthropocene« as a contribution to the »self-description of society,« i.e. to a possible integration of mankind and society into the world."

AbstractSophisticated modeling of the migration of sorbing radionuclides in compacted claystones is needed for supporting the safety analysis of deep geological repositories for radioactive waste, which requires robust modeling tools/codes. Here, a benchmark related to a long term laboratory scale diffusion experiment of cesium, a moderately sorbing radionuclide, through Opalinus clay is presented. The benchmark was performed with the following codes: CORE2DV5, Flotran, COMSOL Multiphysics, OpenGeoSys-GEM, MCOTAC and PHREEQC v.3. The migration setup was solved with two different conceptual models, i) a single-species model by using a look-up table for a cesium sorption isotherm and ii) a multi-species diffusion model including a complex mechanistic cesium sorption model. The calculations were performed for three different cesium boundary concentrations (10−3, 10−5, 10−7 mol / L) to investigate the models/codes capabilities taking into account the nonlinear sorption behavior of cesium. Generally, good agreement for both single- and multi-species benchmark concepts could be achieved, however, some discrepancies have been identified, especially near the boundaries, where code specific spatial (and time) discretization had to be improved to achieve better agreement at the expense of longer computation times. In addition, the benchmark exercise yielded useful information on code performance, setup options, input and output data management, and post processing options. Finally, the comparison of single-species and multi-species model concepts showed that the single-species approach yielded generally earlier breakthrough, because this approach accounts neither for cation exchange of Cs+ with K+ and Na+, nor K+ and Na+ diffusion in the pore water.

Environmental Commitment

Environmental commitment, the subjective experience of dependence on the natural environment, is marked by a long-term orientation and psychological attachment towards the natural environment. The current research replicates and extends previous research on temporarily increasing environmental commitment ( Davis et al., 2009 ). We employed Davis et al.’s manipulation in two experimental studies (one laboratory, one online): we asked participants to spend time writing either about ways in which they are interdependent with the natural environment (high commitment manipulation) or unconnected with the environment (low commitment manipulation). In both studies we replicated the key finding that reflecting on one’s interdependence with the environment increases commitment. We extended the previous research by finding evidence that this commitment effect was mediated by satisfaction with one’s relationship to the environment. We did not replicate the original findings that the interdependence manipulation influences environmental behavioral intentions.

Abstract The importance of estuarine seagrass beds as nurseries for juvenile fish has become a universal paradigm, especially for estuaries that are as important as the Chesapeake Bay. Yet, scientific tests of this hypothesis were equivocal depending on species, location, and metrics. Moreover, seagrasses themselves are under threat and one-third of seagrasses have disappeared worldwide with 65% of their losses occurring in estuaries. Although there have been extensive studies of seagrasses in the Chesapeake Bay, surprisingly few studies have quantified the relationship between seagrass as nurseries for finfish in the Bay. Of the few studies that have directly evaluated the use of seagrass nurseries, most have concentrated on single species or were of short duration. Few landscape-level or long-term studies have examined this relationship in the Bay or explored the potential effect of climate change. This review paper summarizes the seagrass habitat value as nurseries and presents recent juvenile fish studies that address the dearth of research at the long term and landscape level with an emphasis on the Chesapeake Bay. An important conclusion upon the review of these studies is that predicting the effects of climate change on fishery production remains uncertain.

The 2011 tsunami had a devastating effect on the east coast of Japan. Particularly poignant were the century-old markers on hillsides warning against building anywhere below. Nevertheless, such wisdom from traditional knowledge was disregarded because of the perceived invulnerability of the modern. This paper attempts to garner such traditional empirical knowledge regarding the siting of towns and cities by considering the Chinese art/science of fengshui (wind and water) or dili (principles of the earth), the original purpose of which was to site human habitation in the most favourable places for long term survival. This knowledge is then used to consider the placement of cities created by modernity, those founded on and flourishing through the advent of globalisation, such as Hong Kong, Shanghai, St Petersburg, and Sydney.

&lt;p&gt;Terrestrial planets in the Solar system generally lack surface liquid water. Earth is at odd with this observation and with the idea of the giant Moon-forming impact that should have vaporized any pre-existing water, leaving behind a dry Earth. Given the evidence available, this means that either water was brought back later or the giant impact could not vaporize all the water.&lt;/p&gt;&lt;p&gt;We have looked at Venus for answers. Indeed, it is an example of an active planet that may have followed a radically different evolutionary pathway despite the similar mechanisms at work and probably comparable initial conditions. However, due to the lack of present-day plate tectonics, volatile recycling, and any surface liquid oceans, the evolution of Venus has likely been more straightforward than that of the Earth, making it easier to understand and model over its long term evolution.&lt;/p&gt;&lt;p&gt;Here, we investigate the long-term evolution of Venus using self-consistent numerical models of global thermochemical mantle convection coupled with both an atmospheric evolution model and a late accretion N-body delivery model. We test implications of wet and dry late accretion compositions, using present-day Venus atmosphere measurements. Atmospheric losses are only able to remove a limited amount of water over the history of the planet. We show that late accretion of wet material exceeds this sink. CO&lt;sub&gt;2&lt;/sub&gt; and N&lt;sub&gt;2&lt;/sub&gt; contributions serve as additional constraints.&lt;/p&gt;&lt;p&gt;Water-rich asteroids colliding with Venus and releasing their water as vapor cannot explain the composition of Venus atmosphere as we measure it today. It means that the asteroidal material that came to Venus, and thus to Earth, after the giant impact must have been dry (enstatite chondrites), therefore preventing the replenishment of the Earth in water. Because water can obviously be found on our planet today, it means that the water we are now enjoying on Earth has been there since its formation, likely buried deep in the Earth so it could survive the giant impact. This in turn suggests that suggests that planets likely formed with their near-full budget in water, and slowly lost it with time.&lt;/p&gt;

Traditional ritual is a kind of expression of art and culture as well as a form of human appreciation of nature, gained through long term and perpetual processes. Traditional ritual thus can thus be regarded as traditional wisdom. Kawin Cai is one of the traditional rituals in Kuningan society derived from inter religious views. Through this ritual we could tell that the people respect their natural environment for sustainable living. Nonetheless, most of the symbolic practices in the ritual are no longer understood by the people, so that anthropological approach is needed to interpret them.

Abstract. Geosystemics (De Santis 2009, 2014) studies the Earth system as a whole focusing on the possible coupling among the Earth layers (the so called geo-layers), and using universal tools to integrate different methods that can be applied to multi-parameter data, often taken on different platforms. Its main objective is to understand the particular phenomenon of interest from a holistic point of view. In this paper we will deal with earthquakes, considered as a long term chain of processes involving, not only the interaction between different components of the Earth’s interior, but also the coupling of the solid earth with the above neutral and ionized atmosphere, and finally culminating with the main rupture along the fault of concern (De Santis et al., 2015a). Some case studies (particular emphasis is given to recent central Italy earthquakes) will be discussed in the frame of the geosystemic approach for better understanding the physics of the underlying complex dynamical system.

Level Of Analysis

The Anthropocene age is marked by increased human impacts on the natural environment. As social beings, humans interact with each other, and with their surrounding environments, often through organizations and institutions. Religion and the polity are among the most influential human institutions, and they tend to impact the natural environment in several ways. For instance, several thinkers have claimed that some of the central ideas of the Abrahamic traditions, such as the concept of “Domination of men over the earth,” are among the causes of several anthropogenic environmental problems. By contrast, some of the ideas of non-Abrahamic, particularly animistic, religions are found to be associated with environmental conservation and stewardship. The polity can also contribute to environmental problems. The relationship between political organizations and environmental degradation, at any level of analysis from local to global, is well studied and established in the literature. Politicizing the natural environment, however, is not without tradeoffs. Environmentalism, by certain groups of people, is considered as a “stigma,” while it is a central concept in the political ideology of another part of the population. This antagonism is harmful to the environmental protection cause. I make the case that religion, or at least a number of religious ideas, can be conducive to the process of depoliticizing the natural environment. In this paper, I strive to draw a theoretical framework to explain how religion and the polity can mutually impact the natural environment.
