Changing patterns of human resource use and food consumption have profoundly impacted the Earth's biosphere. Until now, no individual taxa have been suggested as distinct and characteristic new morphospecies representing this change. Here we show that the domestic broiler chicken is one such potential marker. Human-directed changes in breeding, diet and farming practices demonstrate at least a doubling in body size from the late medieval period to the present in domesticated chickens, and an up to fivefold increase in body mass since the mid-twentieth century. Moreover, the skeletal morphology, pathology, bone geochemistry and genetics of modern broilers are demonstrably different to those of their ancestors. Physical and numerical changes to chickens in the second half of the twentieth century, i.e. during the putative Anthropocene Epoch, have been the most dramatic, with large increases in individual bird growth rate and population sizes. Broiler chickens, now unable to survive without human intervention, have a combined mass exceeding that of all other birds on Earth; this novel morphotype symbolizes the unprecedented human reconfiguration of the Earth's biosphere.
This paper critically analyses pervasive contemporary discourses that call for children and young people to be “reconnected” with nature and natural resources. Simultaneously, it reflects on emerging forms of nexus thinking and policy that seek to identify and govern connections between diverse sectors, and especially water, energy and food. Both of these fields of scholarship are concerned with connections, of different kinds, and at different spatial scales. Based on a large‐scale, mixed‐method research project in São Paulo State, Brazil, this paper explores how these rather different literatures could be combined in order to (re)think notions of (re)connection that operate across different spatial, political and material registers. Through research with Brazilian professionals and young people about their experiences of, and learning about, the water–energy–food nexus, the paper makes several substantive contributions to scholarship on childhood, youth, environmental education and nexus thinking. Centrally, it is argued that, rather than dispense with them, there are manifold possibilities for expanding and complicating notions of (re)connection, which rely on a more nuanced analysis of the logistical, technical, social and political contexts in which nexuses are constituted. Thus, our work flips dominant forms of nexus thinking by privileging a “bottom‐up” analysis of (especially) young people's everyday, embodied engagements with water, food and energy. Our resultant findings indicated that young people are “connected” with natures and with the water–energy–food nexus, in both fairly conventional ways and in ways that significantly extend beyond contemporary discourses about childhoods–natures (and particularly in articulating the importance of care and community). Consequently, the nexus approach that is advocated in this paper could enable more nuanced, politically aware conceptualisations of (re)connection, both within and beyond scholarship on childhoods–natures and nexus thinking.
Increasingly high-profile research is being undertaken into the socio-environmental challenges associated with the over-production and consumption of food from animals. Transforming food systems to mitigate climate change and hidden hunger, ensure food security and good health all point to reducing animal-based foods as a key lever. Moving beyond animal-based food systems is a societal grand challenge requiring coordinated international research by the social sciences and humanities. A ‘selective openness’ to this range of disciplines has been observed within multi-discipline research programmes designed to address societal grand challenges including those concerned with the sustainability of food systems, inhibiting the impact of social sciences and humanities. Further, existing research on animal-based foods within these disciplines is largely dispersed and focused on particular parts of food systems. Inspired by the ‘Sutherland Method’ this paper discusses the results of an iterative research prioritisation process carried out to enhance capacity, mutual understanding and impact amongst European social sciences and humanities researchers. The process produced 15 research questions from an initial list of 100 and classified under the following five themes: (1) debating and visioning food from animals; (2) transforming agricultural spaces; (3) framing animals as food; (4) eating practices and identities; and (5) governing transitions beyond animal-based food systems. These themes provide an important means of making connections between research questions that invite and steer research on key challenges in moving beyond animal-based food systems. The themes also propose loci for future transdisciplinary research programmes that join researchers from the natural sciences, social sciences, and humanities and stakeholders from beyond academia to develop cooperative research and implementation initiatives. The experiences gained from the prioritisation process draw attention to the value of spending time to discuss and collaboratively steer research enquiry into emergent and controversial matters of concern. Fundamental, ethical questions around the continuation or complete cessation of the use of animals for food was a key tension. The positioning of research towards these questions affects not only the framing of the research area but also the partners with whom the research can be carried out and for whom it may be of benefit.
This edition of Cultural Geographies in Practice serves a dual purpose. It presents a photo-essay that depicts recent and ongoing ‘topographic’ research in London’s Borough Market, and it is an article about photography and topography as textual forms. The photo-essay examines London’s Borough Market through a series of assembled images that relates a narrative of Borough Market and demonstrates the inherent complexity of place. Through its unfolding, it seeks to variously question the ways in which text and pictures can be assembled into types of topographic (re)presentations. The article, presented as an essay, interrogates and simultaneously reclaims the practice of topography. It argues that topography is a methodological intervention into place and place-making as well as a critical spatial practice that can demonstrate place’s inherent complexity. The article further suggests that the implicit reflexivity of the essay-form through which photo-essays emerge allows for a critical spatial practice like topography to be undertaken.
