In a very general sense, hybrid can be understood to be any organism that is the product of two (or more) organisms where each parent belongs to a different kind. For example; the offspring from two or more parent organisms, each belonging to a separate species (or genera), is called a “hybrid”. “Hybridity” refers to the phenomenal character of being a hybrid. And “hybridization ” refers to both natural and artificial processes of generating hybrids. These processes include mechanisms of selective (...) cross-breeding and cross-fertilization of parents of different species for the purpose of producing hybrid offspring. In addition to these processes, “hybridization ” also refers to natural and artificial processes of whole genome duplication that result in the doubling or trebling of the sets of chromosomes of the organism. This entry provides an overview of the impact of hybridity on agriculture. It begins with an historical sketch that traces the early horticulturalists’ and naturalists’ investigations of hybrids. This starts with the observations of Thomas Fairchild and Georges-Louis Leclerc, Comte de Buffon; and leads to the explanation of its mechanism by Gregor Mendel, James Watson and Francis Crick, and Ernst Mayr; and the eventual manipulation of hybrids and hybridization by Barbara McClintock. Following this, the reader is introduced to a number of key terms and concepts in use within current research as well as highlighting diverse ethical concerns that center on hybridization. Recent research that attempts to ascertain the role of hybridization in adaptive change will be introduced. This will include research on the evolution of crop species, increased biodiversity, and the use of hybrids to manipulate phenotypically desirable traits in agricultural crops. The focus of the discussion is on a particularly significant type of naturally occurring hybridization, polyploidy hybridization. Polyploids are organisms which have more than two complete genomes in each cell. This kind of hybridization is ubiquitous among crop plants. The role of polyploidy in plant evolution and the affects of polyploidy on plants and animals will be reviewed. A critical discussion of its agricultural value in the production of fertile polyploid hybrids highlights key epistemological, ontological, and ethical issues. These are illuminated with reference to the distinct processes of artificial and natural hybridization. A survey of these different kinds of hybridization includes the ethical and economic impacts of hybridity on global nutrition, the environment, and considerations of some practical implications for the agricultural industry. Tracking the role of hybrids, the process of hybridization, and the current impacts of it for agriculture requires knowledge of the history of its early conceptualization, understanding, and use. This is the topic of the following section. (shrink)

Energy has an ambivalent status in social theory, variously figuring as a driver or an outcome of social and institutional change, or as something that is woven into the fabric of society itself. In this article the authors consider the underlying models on which different approaches depend. One common strategy is to view energy as a resource base, the management and organization of which depends on various intersecting systems: political, economic and technological. This is not the only route to take. (...) The authors develop an alternative approach, viewing energy supply and energy demand as part of the ongoing reproduction of bundles and complexes of social practice. In articulating and comparing these two positions they show how social-theoretical commitments influence the ways in which problems like those of reducing carbon emissions are framed and addressed. Whereas theories of practice highlight basic questions about what energy is for, these issues are routinely and perhaps necessarily obscured by those who see energy as an abstract resource that structures or that is structured by a range of interlocking social systems.

Some environmental activists occasionally use the argument that poverty is ‘no excuse’ for not going green and denounce discourses putting forward social conditions as unduly exculpatory. Employing participant observation among middle-class activists mobilising to diffuse environmental lifestyles in socially diverse suburbs near Paris (France), the article explores their relation to the working class and examines the consequences of their endeavours on local class relations. It describes the tension between their goal of mainstreaming environmental reflexivity and the stubborn existence of material (...) inequalities and constraints. While their efforts are configured by a moral economy of environmental responsibility which assigns an undifferentiated moral obligation to consume sustainably to all individuals, they make sense of social differences by drawing on culturalist representations of poverty and folk social theories. These sense-making practices enhance rather than alleviate attributions of blame against working-class people and contribute to reinforcing the activists’ dominant symbolic position. (shrink)

In the aftermath of the 1930s Great Depression, and as the Second World War was drawing to a close, Karl Polanyi concluded a critical analysis of market capitalism on an optimistic — and with the benefit of hindsight we can add premature — note, remarking that the ‘primacy of society’ over the economic system had been ‘secured’. Eighty years later, amidst the unresolved turmoil of another comparable global capitalist economic crisis and accumulating signs of a growing environmental crisis, both a (...) direct legacy of the operation of the ‘market economy’, the remedy advocated by governments and policy-makers is effectively a return to ‘business as usual’. Notwithstanding various manifestations of public expression of dissatisfaction with the consequences of global ‘free-market’ capitalism, which include increasing inequality, poverty, unemployment, depletion of scarce natural resources, environmental destruction, pollution and waste, the default policy setting remains to restore global economic growth, to generate further increases in production and cultivate ever-rising rates of consumption, even if the risk is ‘common ruin’. However, there are a number of realistic, progressive and radical alternatives proposed by critical analysts, including a political program for ‘de-growth’, a reinvention of communism and detailed policy proposals outlining the measures necessary to promote a transition to a ‘post-capitalist’ society with a sustainable economy.

The article argues that the work of literary theorist Mikhail M. Bakhtin presents a starting point for thinking about the instrumentalization of climate change. Bakhtin’s conceptualization of human–world relationships, encapsulated in the concept of ‘cosmic terror’, places a strong focus on our perception of the ‘inhuman’. Suggesting a link between the perceived alienness and instability of the world and in the exploitation of the resulting fear of change by political and religious forces, Bakhtin asserts that the latter can only be (...) resisted if our desire for a false stability in the world is overcome. The key to this overcoming of fear, for him, lies in recognizing and confronting the worldly relations of the human body. This consciousness represents the beginning of one’s ‘deautomatization’ from following established patterns of reactions to predicted or real changes. In the vein of several theorists and artists of his time who explored similar ‘deautomatization’ strategies – examples include Shklovsky’s ‘ ostranenie’, Brecht’s ‘ Verfremdung’, Artaud’s emotional ‘cruelty’ and Bataille’s ‘base materialism’ – Bakhtin proposes a more playful and widely accessible experimentation to deconstruct our ‘habitual picture of the world’. Experimentation is envisioned to take place across the material and the textual to increase possibilities for action. Through engaging with Bakhtin’s ideas, this article seeks to draw attention to relations between the imagination of the world and political agency, and the need to include these relations in our own experiments with creating climate change awareness.

This paper decentres the predominance of statism and deliberation in ecological democracy scholarship. We use insights from eco-anarchism and cosmopolitics to identify democratic configurations beyond capitalism and its entanglement with the nation-state. These configurations are premised on the idea that sustainability transformation not only implies a move beyond capitalism and the nation-state, but might comprise their dismantling. We propose and apply an analytical framework encompassing the dimensions actors, praxis and processes and institution(s) to contrast these three political theories and bring (...) forward a diversity of democratic praxes that revolve around the generation of autonomy and the building of multispecies political communities. Finally, we discuss transformation possibilities from within the capitalist nation-state and propose research directions for post-statist, autonomous and diverse ecological democracies. (shrink)

Social theorists have been dealing with issues of environment and climate change for quite some years, but on which topics have they focused and with whom have they been talking? Many of the articles included in this special issue exemplify a tendency to frame problems of climate change in terms of existing concerns, including the character of capitalism, the relation between nature and culture, or the social process of problem definition. Other forms of conceptual development are much more obviously driven (...) by the challenge of understanding and perhaps fostering societal transformation in response to climate change. Meanwhile, policy proceeds on the basis of a characteristically thin account of the social world. In this short article I highlight differences in how these agendas unfold and comment on what this means for types of questions that social theorists have often, sometimes and not yet asked about climate change. I conclude that social theory — broadly defined — has much to offer but that realizing this potential will require concerted effort and active engagement with new and unfamiliar audiences. (shrink)
