Marine aerosols can enter the terrestrial environment via sea spray which is known to affect the stable isotope fingerprint of coastal samples (plants, animals/humans), including δ13C. However, the impact of sea spray on 14C dating of terrestrial organisms at coastal sites has not been investigated so far. Besides a direct effect, sea spray is accompanied by physiological effects, e.g., due to salinity. In an artificial sea spray experiment in the greenhouse, the effect of sea spray on 14C in plant tissue was investigated. Beach grass was sprayed with mineral salt solutions containing only traces of NaCl or with brackish water from the Schlei inlet or the Baltic Sea. These plants should give a 14C signal close to the modern atmospheric 14CO2 composition. However, three treatment groups showed variable radiocarbon concentrations. Plants sprayed with water from the Schlei inlet, Baltic Sea water, or with a mineral salt solution with very high HCO3– concentration are depleted in 14C content relative to contemporary atmospheric composition. While δ13C reflects physiological effects in the plants, caused either by salinity (NaCl) or HCO3– stress, resulting in decreased discrimination against 13C, the uptake of high amounts of 14C (ca. 53–67%) from DIC (dissolved inorganic carbon) partly masks the underlying physiological reactions, as is visible in the radiocarbon signature of the plant tissues. This preliminary study indicates that sea spray effects on plant tissue could potentially influence faunal tissue 14C composition at coastal sites. Further research is required to better understand the observed reservoir effect.
We report here an isolated insect forewing from Triassic deposits of the Eisenhower Range, northern Victoria Land, Antarctica. Based on the reduced venation (e.g. well-developed pterostigma, Rs dichotomously branched, Rs and M vein with five branches each), we tentatively identify the specimen as belonging to Permochoristidae (Mecoptera). However, due to incomplete preservation of the forewing, we prefer a determination under open nomenclature until more material of this taxon is available. The new specimen represents the first insect described from the Triassic of Antarctica and the first fossil record of Mecoptera in the continent, supporting the worldwide distribution and a greater diversity of the family during Triassic times.
The Manych Depression is a relatively narrow elongated depression of tectonic origin, connecting the Caspian and Azov-Black Sea basins. The Caspian Sea repeatedly discharged its waters through this depression into the Black Sea and further into the Mediterranean Sea during the Quaternary period. The last discharge occurred in MIS 2 when the Khvalynian transgression waters exceeded the drainage divide between those two basins. The geochronology of the last flow of Caspian waters into the Black Sea was established recently based on 14C dating of Khvalynian shells, carried out mainly by liquid scintillation counting, and the end of this event was dated to 12.5–12.8 ka cal BP. Recently obtained OSL dates for one of the most complete sections of the Khvalynian deposits of the Manych Depression indicate an older time for the end of the flow. This study aimed to clarify the timing of the Khvalynian transgression discharge by examining two sections containing the Khvalynian mollusk fauna in layers that, according to their stratigraphic and geomorphological position, belong to the final phase of the flow of the Caspian waters. Four 14C AMS dates were obtained from single shells of Didacna ebersini and Hypanis plicata, which agree with the OSL dating results. The results indicate that the last overflow of Caspian waters through the Manych Depression had ceased at around 14.5 ka cal BP.
Edward Said (1978) introduced the notion of imaginative geography: Groups with a hunger for land essentially reimagine the landscapes they desire, elevating the notion of themselves as the owners of the land they seek, a process of reinventing the meaning of territorial landscapes as ‘imagined geography’. This would help them frame arguments justifying why they are entitled to take possession of the landscapes they desire. Before the actors themselves see and conquer the land, they entertain themselves under a discursive understanding that they are the owners of the landscapes that they covet. Hence, this imaginative geography is a theory of human action deriving from the interplay of material impulses and human consciousness (Gregory 1999); it is ‘performative’. Reimagining landscapes is the first step to acting upon them and creating the very outcomes on the land being imagined (Gregory 2004: 17–20). In this process, hegemonic forces with territorial ambitions refashion themselves as owners of the territory they desire by asserting themselves as masters and sovereign of the land.
Here, one wonders, what is the landscape that has emerged as part of the subaltern project of the imagined geographies? This entails the counterimagination and a contra-discourse of the imaginative geographies by the oppressed, intertwined with the notion of egalitarianism and justice, which could be realized through ecospatial struggles. If this imagined landscape and the struggle for the same is for livelihood and basic human and ‘post-human’ survival, the struggling poor would be forced to follow the logic of their own ‘moral economy’ that historically protected their rights to subsistence (Thompson 1991). The large number of ‘land-wars’ (Levien 2013) that have been taking place in Latin America and Asia, particularly in India, offers how the subalterns imagine their struggles as part of their livelihood and citizenship rights. If it was Muthanga in Kerala in 2003, it was Chengara in 2007. If Muthanga was occupied by the Adivasis, it was the Dalits – formerly the agrestic slaves and the most marginalized of all the outcastes of the Hindus – that occupied the Chengara part of the colonially evolved Harrisons Malayalam plantations. Even after three and a half decades of land reform experimentation how does one explain the Dalit land struggles in Kerala? Can Chengara replace Occupy Muthanga in terms of strategies, struggles, and outcomes? How far did the state succeed or fail in addressing the Dalit land question, their resource endowments, and livelihood?
This chapter addresses how politics, epistemology, and modernity are co-produced, and, in this process, how the pre-defined notions of politics, epistemology, and modernity themselves are transformed and reconstructed. The emergent theoretical framing is empirically informed by the place-specific campaign against the aerial spraying of endosulfan pesticide wherein ‘life is cheaper than cashew’. The chapter highlights the structural connections between global capitalism and state-driven developmentalism but also how the very state was conscientized by the transverse solidarity of the ‘constituent power’, including the victims and the larger civil society as agents of modernity, the latter understood as resistance for egalitarianism. However, it does not stop there. We shall also touch upon the ‘epistemological break’ (Bachelard 1938; Althusser 1969) that has occurred in the larger context of knowledge controversies and conflicts (see Whatmore 2009).
In May 2010, the left-front government in the Indian state of Kerala took the historic decision to ban more than a dozen toxic pesticides in the state. This was the culmination of over a decade and a half of struggle and movements in protest against the aerial spraying of endosulfan on the state-owned cashew plantation in the northernmost district of Kasaragod. This chapter follows the prolonged struggle led by the victims of the deadly pesticide, the awakening of a general consciousness among the public, the building up of transverse politics and solidarity, and, finally, the persuasion of the state to ban the pesticide, along with other toxic wastes. The chapter is situated in the larger context of what Beck (1986), Habermas (1987), and Gaonkar (2001) would call risk society, a society in which modernity has become ‘a theme and a problem for itself’, and thus the crisis inherent in it is to be managed through a reinvention of politics. The chapter suggests that the concept of risk society and reflexive modernity as the outcome of a series of struggles and movements demanding the ban on endosulfan in the state offers fresh insights into the power of the people and the civil society in joining the victims.
This chapter explores ecoviolence along the Sea of Cortez, and Mexican cartels’ decades-long monopoly of the illegal drug market. Through this illicit economy, we unpack the convergence of illegal waste dumping, the illegal wildlife trade, money laundering, and human smuggling, and the role that Mexican, Chinese, and Fujian criminal organizations play in regional, interregional, and transnational exchanges to further criminal activities. The Sea of Cortez is a fascinating case study due to its geographic location as a historical hub for smuggling multiple commodities such as totoaba bladders, shark fins, drugs, diamonds, and precious metals. But the smuggling of immigrants has now come under the purview of these criminal networks. The chapter concludes with proposing a new analytical framework for studying ecoviolence, building expert capacity for undertaking research and analysis of policy development and enforcement.
Alain Badiou points out that subjects become political when they create events – events as trans beings (see Hallward 2003; Badiou 2005, 2009) – even without the mediation of an agency. Badiou (see Hallward 2004) would also constantly remind us that what is important is post-eventual declaration: to quote Lisy Sunny, one of the Dalit woman leaders of Pombilai Orumai in Munnar, ‘[A]t least now we have a union of our own.’
The protests that rocked the Kanan Devan tea plantations, formerly Scottish James Finlay, in Kerala in 2015, led by the historic Pombilai Orumai – the women's unity – and later a parallel state-wide struggle spearheaded by the mainstream trade unions had been called off following what could best be described as mixed outcomes. While the plantation management has had to shift its position with regard to its decision not to increase the bonus or wages, the workers had to content themselves with a 30 per cent hike in wages as against their original demand for a 100 per cent increase. Yet the struggle has been path-breaking as it helped bring to light the harsh living and working conditions on the colonially evolved plantations. The company's claim that it ‘ranked No. 1 in the category [of] best company for employees’ involvement and participation in India’ and ‘featured among the 100 best companies to work [as per] its employees in India’ was exposed as an untruth. In fact, the observations made at the second All Kerala Thozhilali Sammelanam (All Kerala Workers’ Meet) held at Trichur in 1937 under the leadership of veteran communists including P. Krishna Pillai, N.C. Sekhar, R. Sugathan, and A.K. Gopalan, that of all the workers it was the plantation workers who suffered the most (see Raman 2010), remains true to this day – after nearly seven decades of Indian independence – with hardly a change in the historically evolved plantation-based patriarchal forms of exploitation/oppression.
