Performance is a useful lens through which to analyze agrarian life, as performance illuminates the ways that farmers manage the complex socioecological demands of farm work while participating in social life and in the larger political economy. The dialectic of planning and improvisation in the farm field has produced scholarship at multiple scales of political ecology, including the global ramifications of new technologies or policies, as well as the hyper-local engagements between farmers and fields in the context of modernity and development. Political ecologists are also beginning to understand how affects, such as aspirations and frustrations, influence agriculture by structuring how farmers and other stakeholders make decisions about farms, households, capital, and environments. To understand farm work as a performance is to situate it within particular stages, roles, scripts, and audiences at different scales. The articles in this Special Section ask how farmers have improvised, planned, and performed in response to agroecological challenges, bridging scholarship in political ecology, development studies, and the study of agrarian landscapes through new empirical case studies and theoretical contributions. Agriculture both signals social values and fosters improvisations within farming communities' collective vulnerability to weather and the political economy. We argue that the lens of performance situates the political ecology of agriculture within the constraints of the political economy, the aspirations and frustrations of daily life, and the dialectic between improvised responses to change and planning in the field.Keywords: Performance, agriculture, planning, improvisation, agrarian studies

This book advances Earth Stewardship toward a planetary scale, presenting a range of ecological worldviews, practices, and institutions in different parts of the world and to use them as the basis for considering what we could learn from one another, and what we could do together. Today, inter-hemispheric, intercultural, and transdisciplinary collaborations for Earth Stewardship are an imperative. Chapters document pathways that are being forged by socio-ecological research networks, religious alliances, policy actions, environmental citizenship and participation, and new forms of conservation, based on both traditional and contemporary ecological knowledge and values. 'The Earth Stewardship Initiative of the Ecological Society of America fosters practices to provide a stable basis for civilization in the future. Biocultural ethic emphasizes that we are co-inhabitants in the natural world; no matter how complex our inventions may become' (Peter Raven).

Scientists have traditionally collected data on whether a population is increasing, decreasing, or staying the same, but such studies are often limited by geographic scale and time frame. This means that for many species, understanding of trends comes from only part of their ranges at particular periods. Working with citizen scientists has the potential to overcome these limits. Citizen science has the added benefit of exposing citizens to the scientific process and engaging them in management outcomes. We examined a different way of using citizen scientists (instead of data collection). We asked community members to answer a question directly and thus examined whether community wisdom can inform conservation. We reviewed the results of 3 mail-in surveys that asked community members to say whether they thought koala populations were increasing, decreasing, or staying the same. We then compared the survey results with population trends derived from more traditional research. Population trends identified through community wisdom were similar to the trends identified by traditional research. The community wisdom surveys, however, allowed the question to be addressed at much broader geographical scales and time frames. Studies that apply community wisdom have the benefit of engaging a broad section of the community in conservation research and education and therefore in the political process of conserving species.

AbstractCities in the global South are often considered to be in the midst of infrastructural breakdown, and characterized as either lacking networked services or as suffering from ongoing disruption and sometimes failure. This article focuses on the electricity network of Accra to examine the series of socio‐natural processes that produce this ongoing disruption and to explore the power relations of networked systems in the city. It focuses on the production of disruption through the analytical lens of urban political ecology, in order to show how such a framework can be utilized to interrogate energy geographies. The article begins by describing what happens when the lights go out and the flow of electricity is interrupted across Accra in order to connect a series of socio‐natural processes that contribute to the ongoing network disruption and interruption. The article establishes the effect of historical infrastructural governance, greenhouse gas emissions, flows of international capital, water and drought in northern Ghana, as well as urban sprawl, slum urbanism and rising energy demand in the city, to illustrate the fundamentally unequal and politicized socio‐natures of these disrupted infrastructural processes.

Abstract
In this article, I contrast two of the main schools of thought within eco-Marxism, namely Metabolic Rift (MR) and World-Ecology (WE). These differ above all else in their accounts of the ontological status of society and nature. The Covid-19 pandemic constitutes a moment of concretisation of this long-standing debate, which is able to dissolve at least in part its issues. The article consists of four parts. I begin with a summary of the two schools of thought and their core stances, before proceeding to unpack their respective theoretical points of contention. I subsequently proceed to explore the conceptualisation of health according to the Marxist scientists Richard Levins and Richard Lewontin through the model of dialectical biology. In the third section, I unpack the conceptualisation of the Covid-19 pandemic by the epidemiologist Robert Wallace, before finally concluding with the contrasts of the two schools in the light of dialectical biology.
