Description: The Mississippi River maintains commercial and societal networks of the USA along its 〉3700 km length. It has accumulated a fluvial sedimentary succession over 80 million years. Through the last 11,700 years of the Holocene Epoch, the wild river shaped the landscape, models of which have become classic in geological studies of ancient river strata. Studies of the river were led by the need to develop infrastructure and to search for hydrocarbons, through which, these models have become quite sophisticated. However, whilst the models demonstrate how the wild river behaves, a monumental shift in fundamental controls on the entire fluvial system, broadly coinciding with the proposed mid-20th century onset of the Anthropocene Epoch, has generated new geological patterns that are becoming globally ubiquitous, and which the Mississippi River typifies. As such, whilst classic Holocene river models may be compared to human-modified systems such as the Lower Mississippi River (and others worldwide), locally the models may now only directly apply to its fossilized components preserved in the sub-surface. Such river models need adapting to better understand the present dynamics, and future evolution of these landscapes.

Description: With the help of the concepts ‘aura’ and ‘autopoiesis’, the relationship between poetry and natural phenomena can be defined as a ‘translation from nature’. Gennadij Ajgi translates his auratic manner of perceiving into poetry. For him, the poem becomes an epistemic medium transcending the sensory perception of nature for a hidden, spiritual level. Les Murray, conversely, demonstrates an autopoietic understanding of nature: The poet himself becomes the medium of the living being. Christian Lehnert takes up impulses from both orientations. He combines the opposing concepts so that they correspond to the hierarchical levels of his religious and metaphysical vision of the world. The three authors all aim to alter the attitude of humans towards nature through their ‘translation from nature into poetry’ so that humankind will open itself towards nature and raise it from an object which can be instrumentalised to an autonomous subject on equal footing with humanity itself.

Description: The paper discusses the CF-industries ammonia plant in Donaldsonville, Louisiana. The plant is framed as an exemplary site from which the Anthropocene can be observed and understood. In doing so, a proposal for a “chemical cultural theory” is set out, to allow us to understand such molecular planetary technologies and interpret their (geo)historical significance. As one of the largest fertilizer plants in the world in terms of its output, and one of the largest chemical plants along the “Petrochemical Corridor,” a cluster of chemical industries situated between Baton Rouge and New Orleans, Donaldsonville typifies the relations between the nitrogen and hydrocarbon industries. Catalysis is here used both as a chemical concept and as a metaphor central to the proposed chemical cultural theory. As key to the Haber-Bosch process and refinery technologies in general, investigating the role of catalysis allows us to connect the history of the Petrochemical Corridor to that of German industrialism. This relation reveals how, from the late 19th century through to the World Wars, an ambivalent industrial co-operation between the US and Germany not only transformed local and planetary environments, it also contributed to the Anthropocene condition.

Description: The Mississippi River Basin is a vast near-planar surface, an area upon which sunlight falls and wind flows. Its gently banked geomorphology channels precipitation, sediment, biota, and human activity into a dynamic locus of regional Earth system interactions. This paper describes the major features of this region’s energy exchanges from a thermodynamic Earth systems perspective. This analysis is combined with descriptions of the historical and socio-political contexts that have helped shape energy use. In doing so, the paper contrasts the region’s available energy exchanges and flows with their anthropogenic diversion, providing an account of human impact at a regional scale. It also offers theoretical estimates of the potential availabilities of renewable energy. This is contrasted with a description of the geological formation of stocks of fossil energy in the region. On these bases, a number of maps are presented and an assessment of the region’s energy flows is offered. These exercises point to significant affordances for achieving regional de-fossilisation at the river basin scale.

Description: This report draws upon political ecology and nature–society geography to examine the production network–nature nexus. Indebted to these approaches, a growing number of production network and value chain studies are expanding well beyond the field’s traditional remit of environmental governance. This work centers the institutional arrangements of firms, laboratories, workers, and regulations that organize and combine extensive and intensive strategies to appropriate nature’s value. ‘Nature’ is neither input nor output here; rather, it is metabolized in and through the functional coordination of these spatially distributed activities. I explore these themes in recent studies of resource extraction and frontier-making, chemical geographies of biocides, and the material-cum-geographical claims of ethical supply chains. Expanding and deepening the dialogue between conjunctural analyses of states, labor, and supply chains, on the one hand, and how socionatures condition these arrangements, on the other, is both analytically and politically necessary. I offer this, my final report, as a modest contribution to this endeavor.

Description: Dynamic and unrestrained socio-economic development is upsetting the balance of nature’s mechanisms, causing a climate stalemate, or even climate destabilisation. After the Second World War a new political system – real socialism – was enforced on Poland. It brought about changes of a social, cultural, economic and environmental nature. Its immanent feature was the application of top-down decisions that did not take into account environmental components. There was also little ecological awareness within Polish society at that time. The transformations of the 1990s resulted not only in the liberalisation of the Polish economy, but also in the permeation of new trends oriented towards pro-environmental activities. The aim of the article is to find an answer to the question: How is ecological awareness currently shaped in the context of Anthropocene in Poland during the transition from a socialist economy to a capitalist economic system?

Description: The Cape Canaveral Peninsula is the largest Holocene coastal sand deposit composed of beach ridges on the Atlantic coast of Florida. It is composed of 16 beach-ridge sets that are separated by erosional surfaces. Despite its prominence as a Holocene coastal depocenter, there are a limited amount of chronological data constraining the timing of its formation. In this study, we apply optically stimulated luminescence (OSL) dating on sand-sized quartz and radiocarbon dating on individual marine shells to develop a refined chronology of the Cape Canaveral beach-ridge plain with particular focus on constraining the depositional age of the northwesterly-most, and geographically oldest, beach-ridge set on the peninsula. We obtain an average OSL age of 5680 ± 240 years ( n = 4) for the initiation of coastal deposition at Cape Canaveral. The new ages, and the organization of beach ridges into 16 distinct sets indicates that the Cape Canaveral beach-ridge plain experienced an ~5700-year history of alternating deposition and erosion, with 75% of present-day Cape Canaveral (Beach-ridge Sets 5–16) deposited over the past 2000 years and Beach-ridge Sets 8–16 comprising 50% of the area over the past 1000 years. Because the minimum swale elevations of the ~5700-year Beach-ridge Set 1, and those of all the younger beach-ridge sets, are within several decimeters of present-day mean higher high water, we hypothesize that all the beach ridges present at Cape Canaveral could have been deposited at or within decimeters of present-day sea level. There is no evidence for Holocene “highstand” events over the past 5700 years in the published sea level curves from northeast and south Florida, which are based on subsurface estuarine foraminifera/leaf litter and mangrove peat data, respectively. This dichotomy illustrates the need to integrate both subaerial and subsurface data to produce a more realistic Holocene sea-level curve for the southeastern United States.

Description: Training animals to pull agricultural equipment and wheeled transport significantly shaped and advanced human economic systems. In this context the use of large domestic animals such as cattle was a milestone event in human history, part of what Sherratt memorably termed the Secondary Products Revolution: the use of the products of live animals such as milk, wool and traction power. It is commonly assumed that male cattle were generally preferred for traction because of their greater strength compared with females, and the importance of the latter for breeding and, in some societies, for milk and for dairy products, but surprisingly little is known of this aspect of the Secondary Products Revolution in prehistoric China. Here we apply established morphometric models to 10 assemblages of cattle bones from Chinese Bronze Age (ca. 2000–221 BCE) contexts. Our results indicate a process of intensified cattle labour exploitation at this time and, intriguingly, we also observe the earliest labour employment of female cattle during the Late Shang dynasty (ca. 1300–1046 BCE). It is proposed that female cattle may have been required for traction because of the large numbers of male cattle, especially bulls, that were sent for ritual sacrifice. Such a strategy reveals a sophisticated social management, upon which the Late Shang civilisation eventually developed.

Description: Radiocarbon dates from 176 sites along the Delmarva Peninsula record the timing of deposition and sea-level rise, and non-marine wetland deposition. The dates provide confirmation of the boundaries of the Holocene subepochs (e.g. “early-middle-late” of Walker et al.) in the mid-Atlantic of eastern North America. These data record initial sea-level rise in the early Holocene, followed by a high rate of rise at the transition to the middle Holocene at 8.2 ka, and a leveling off and decrease in the late-Holocene. The dates, coupled to local and regional climate (pollen) records and fluvial activity, allow regional subdivision of the Holocene into six depositional and climate phases. Phase A (〉10 ka) is the end of periglacial activity and transition of cold/cool climate to a warmer early Holocene. Phase B (10.2–8.2 ka) records rise of sea level in the region, a transition to Pinus-dominated forest, and decreased non-marine deposition on the uplands. Phase C (8.2–5.6 ka) shows rapid rates of sea-level rise, expansion of estuaries, and a decrease in non-marine deposition with cool and dry climate. Phase D (5.6–4.2 ka) is a time of high rates of sea-level rise, expanding estuaries, and dry and cool climate; the Atlantic shoreline transgressed rapidly and there was little to no deposition on the uplands. Phase E (4.2–1.1 ka) is a time of lowering sea-level rise rates, Atlantic shorelines nearing their present position, and marine shoal deposition; widespread non-marine deposition resumed with a wetter and warmer climate. Phase F (1.1 ka-present) incorporates the Medieval Climate Anomaly and European settlement on the Delmarva Peninsula. Chronology of depositional phases and coastal changes related to sea-level rise is useful for archeological studies of human occupation in relation to climate change in eastern North America, and provides an important dataset for future regional and global sea-level reconstructions.

Description: Climate change and human activities have been an important part of studies regarding historical environmental changes in China over the past 2000 years. In this study, we focused on environmental changes, that is, natural disasters and human activities, in the Poyang Lake Basin over the past 2000 years, to analyze interactions between land use cover changes and human activities from the perspective of regional sustainable development. We collected historical records of climate and hydrology, floods and droughts, and rivers and lakes in the Poyang Lake area, and established time sequences for the floods and droughts, lake water level and lake area, amount of farming land, and population, in order to discuss interactions between changes in the environment and the climate, with emphasis on the impacts of extreme events on lake and river basin environment changes. The following results were obtained. First, climate changes in historical periods had wide-ranging and far-reaching impacts on agricultural production, especially disasters caused by climate change. Among the changes in the Poyang Lake basin environment, including river network systems, lake water levels, etc., changes in lake water volume are direct evidence of climate change, adaptation to climate change, and obvious phased characteristics. Second, in the process of changes to the lake and river network in the Poyang Lake Basin, social and economic development is accompanied by evolution of the lake. Increases and decreases in population, the scale of agricultural production, and lake environment changes have direct and significant interactions. Third, the Poyang Lake basin’s environmental changes during the historical period are mainly reflected in the pressure feedback mode of “population–agriculture” in the lake environment.
