Edward Abbey’s Desert Solitaire and Barbara Kingsolver’s Prodigal Summer urges readers to see coyotes as crucial members of the natural community whose predation is essential for the maintenance of biodiversity and ecological stability. Their cultural production provides a human story of ecocritical engagement for understanding the cascading effects of removing top predators from their ecosystems. By envisioning biocentric possibilities within place-based and scientific contexts, Edward Abbey and Barbara Kingsolver share a common theme of political ecology: political processes shape ecological conditions. A close reading of Edward Abbey’s Desert Solitaire and Barbara Kingsolver’s Prodigal Summer provides a literary entryway to connect research, arguments, and discourse across disciplines tasking readers to engage in political discussions of environmental sustainability and to consider viable solutions to preserve the ecological diversity of our predator populations and ecosystems.

In recent years, Senegal has proactively pursued the expansion of renewable energy generation, particularly from solar and wind. In addition to starting exploration of offshore liquefied natural gas, the expansion in renewable energy is posited as a way to help the country move toward low(er) carbon development, reduce dependence on volatile oil markets, and improve reliable (and especially rural) access to electricity. To achieve these objectives, the electricity sector has continuously undergone structural reforms to improve its financial viability and to achieve objectives around universal access to electricity, particularly by increasing private sector participation in electricity generation. Through the lens of “electricity capital,” this paper examines the implications of reforms in the electricity sector for processes of accumulation, in a context of efforts to improve environmentally sustainable development. It asks how capital in the electricity sector is constituted and operates in the Senegalese context, who has power in shaping how it operates, and how this has influenced the potential for achieving a fair and equitable transition to a low(er) carbon energy system. This paper draws on recent work in political ecology on energy transitions and emerging literature on the political economy of electricity, as well as on analysis of policy and technical documents and semi-structured interviews carried out with those involved in the energy sector between 2018 and 2020. Findings suggest that even though the Senegalese government has set clear objectives for the electricity sector that are based on principles of equity, environmental sustainability, and justice, the current power relations and financing arrangements taken on by the state and other actors active in the sector has, paradoxically, led to an approach that risks undermining these very principles.

Endosymbionts occur in most plant species and may affect interactions among herbivores and their predators through the production of toxic alkaloids. Here, we ask whether effects of mycotoxins produced by the symbiosis of the fungal endophyte Neotyphodium lolii and the grass Lolium perenne are transmitted to the aphidophagous ladybird Coccinella septempunctata when feeding on cereal aphids Rhopalosiphum padi on infected plants. The larval development of coccinellids was extended, while their survival was reduced when feeding exclusively on aphids from infected plants. Ladybirds developing on aphids from infected plants showed reduced fecundity and impaired reproductive performance. Body size and symmetries of ladybird adults were not affected by the endophytes. Consistently strong, negative effects of endophytes on the lifetime performance of ladybirds indicates that mycotoxins are transmitted along food chains, causing significant damage for top predators. Such cascading effects will influence the population dynamics of aphid predators in the long term and could feedback to the primary plant producers.


Purpose. Determination of ecological stability of landscapes of the basin of the Western Bug River and its tributaries in Volyn region. Methods. Comparative-geographical, analytical, generalization, systematization, calculation of ecological stability of the landscape on the basis of the method of E. Clementova, V. Heinig. Results. The calculation of the quantitative assessment of the ecological stability of the landscapes in the basins of the Western Bug tributaries revealed that the KESL1 index of the Pischadka, Neretva and the Zolotoha River ranges from 1.3 to 1.6. That making basin landscapes conditionally stable. River Studyanka and Luga range from 0,027 to 0,026, which testifies them to the unstable structure of the landscapes of the basin with pronounced instability. It is established that in the landscapes of the basin of the Western Bug River of Volyn Region, their ecologically balanced structure is predominant at the KESL1 1.04 index. This is due to the structure of the lands of the basin, where agricultural (arable land) cause a big loading and destabilized landscapes occupies in most of the area. The largest plots of arable land occupy the sub basins of the rivers Studyanka and Luga, and the smallest ones in the sub basins of the Neretva, Zolotukha and Gapa rivers, which is due to the significant forested areas of the basin. The qualitative assessment of ecological stability of the landscape is characterized by the coefficient of ecological stability of the biotechnical elements of the entire landscape of the K ESL2. Calculations of KESL2 showed that the landscape structure of the basin of the Western Bug River in the Volyn region is slightly stable and the index is 0.48. The KESL2 coefficients of the Studyanka and Lug lakes are 0.21 and 0.23 respectively, and characterize them as unstable geosystems. The structure of the landscapes of the basins of the Peschadka and Kopayevka rivers for KESL2 - (0,95 - 0,67) is stable. Consequently, intensive settlement of land, drainage of marshes, deforestation violated the integrity of landscapes led to their denaturalization. Particularly significant changes occurred in the southern part of the basin. Conclusions. As a result of the calculations of the quantitative assessment of the ecological stability of landscapes (KESL1), the landscapes of the basin of the Western Bug River in the Volyn region are conditionally stable. And according to the indicators of qualitative assessment of ecological stability of the landscape (KESL2), they are characterized as low-static geosystems. In general, determining the stability of the landscape is important for assessing the ecological situation of the basin of the Western Bug River, since it fully reflects the overall ecological status of the river basin.

<p>People understand their relationship, and that of broader society, with nature in a diverse range of ways. Yet the expression of such diversity is often constrained in decision making processes, and in western contexts, neoliberalised understandings of nature are often privileged. Feminist political ecology provides a nuanced approach to exploring how meanings of nature are made and remade, and how some meanings come to be dominant. An emergent body of political ecology has begun to draw on radical democratic theory to shed light on how this privilege is created and perpetuated in political processes in ways that channel certain outcomes. In extending this engagement between theories, this research explores how different understandings of nature compete in formal and informal political spaces through the case study of a new water management regime. For more than a decade, debate has raged about whether or not to dam the Hurunui River for irrigation. Such debate about the future of freshwater bodies has characterised politics in the Canterbury region through which the Hurunui flows. Canterbury has seen rapid agricultural intensification that has been enabled by the enclosure of freshwater. However, enclosure has been contested, and this contestation came to a head when, in early 2010, the national government intervened and dramatically reregulated freshwater in the region; elections for the regional council were suspended, access to judicial reconsideration of decisions about the environment were severely narrowed, and processes underway to protect freshwater bodies were interrupted. Promising better environmental democracy, central government, and the appointed officials replacing the elected councillors, endorsed a new freshwater management initiative based on devolved collaboration and consensus building. In response to conflict over the Hurunui River, the catchment was the first area in which this initiative was tested, a process that became the case study for this project. Through a feminist poststructural approach, I conducted and analysed 42 semi-structured interviews with those involved with Hurunui politics, and was a participant observer at 12 meetings of the new collaborative committee for the catchment. I argue that there were multiple processes that worked to channel particular understandings of nature, and facilitate the enclosure of freshwater for economic advantage. This channelling occurred in three key ways. Firstly, reregulation in Canterbury removed many democratic rights, limiting opportunities for participation in water politics. Secondly, the devolved collaborative and consensus based water committee was constrained by targets and discourses that determined that more water needed to be enclosed to serve a neoliberal growth agenda. Thirdly, community was privileged as a scale of democracy. As a result, narrow constructions of community belonging and performance remained unexplored, and these constructions inhibited public debate and limited possibilities to articulate and explore difference. I argue that such everyday experiences of power and constrained agency constitute an important dynamic of nature politics. There were, however, hopeful aspects of the new regime. An emphasis on dialogue led to transformative social learning, particularly about Ngāi Tahu, the Māori iwi (tribe) with traditional authority over the region, and the ways the iwi negotiated and enacted a relational ethics with the river. This study argues that considerations of power must be at the forefront of democratic design and uneven power relations need to be engaged with in such a way that multiple understandings of nature and society can be articulated and seen to be legitimate. Such an approach provides possibilities for political space in which to reimagine environmental futures and contest the dominance of neoliberal natures.</p>

The Khorezm oasis sits at the epicenter of an environmental disaster. Since the late 19th century, the continual expansion of irrigation in this region has altered the natural hydrology of the Amu Darya delta, leading to widespread desertification and the near total disappearance of the world's fourth largest lake, the Aral Sea. The situation is widely acknowledged as an environmental catastrophe of unprecedented scale, and yet it is not the first irrigation crisis in Khorezmian history. Numerous events of irrigation collapse are recorded in the archaeological record of this oasis, with many in the scientific community now very interested in this past record for its potential to inform on the modern crisis. Unfortunately, there has also been a tendency to overlook the different historical conditions that led to irrigation in this oasis over the last three millennia. In this article, I take an alternative approach that draws on political ecology's insights about the cultural embeddedness of environmental behavior. I compare two periods of irrigation in Khorezm, one ancient and the other modern, to show how the particular social contexts of each period shaped irrigation schemes in different ways. Significantly different design and implementation features are apparent in the ancient versus modern systems, with vastly different implications for environmental sustainability and human well-being.Keywords: water, irrigation, Aral Sea, archaeology, collapse, Soviet Union, nomadic pastoralism

In this work, we propose a multifishing area prey-predator discrete-time model which describes the interaction between the prey and middle and top predators in various areas, which are connected by their movements to their neighbors, to provide realistic description prey effects of two predators. A grid of colored cells is presented to illustrate the entire domain; each cell may represent a subdomain or area. Next, we propose two harvesting control strategies that focus on maximizing the biomass of prey, in the targeted area, and minimizing the biomass of middle and top predators coming from the neighborhood of this targeted area to ensure sustainability and maintain a differential chain system. Theoretically, we have proved the existence of optimal controls, and we have given a characterization of controls in terms of states and adjoint functions based on a discrete version of Pontryagin’s maximum principle. To illustrate the theoretical results obtained, we propose numerical simulations for several scenarios applying the forward-backward sweep method (FBSM) to solve our optimality system in an iterative process.

In Sub-Saharan African countries, governments are increasingly devolving natural resource management from central administration to the local government level as a trend toward subsidiarity. In parallel, efforts to implement formalization processes have resulted in a puzzling institutional arena, wherein mixed actors are struggling to influence the paths of institutional change and the associated distribution of land and land-related resources. Relying on political ecology and new institutionalism in social anthropology, we investigate how the decentralization of formalization of rights in artisanal and small-scale gold mining can lead to paradoxical outcomes, often negatively impacting social, economic, and environmental sustainability. Two comparative case studies are performed in Ghana. Our results show that the negative effects of formalization efforts for resource end users are to be understood in the broad context of actors’ repositioning strategies following the selective implementation of decentralization. The authors conclude that increasing the power of the central government and line ministries to control local resources can influence the disenfranchisement of local people’s participation and control of natural resources, resulting in a relentless environmental crisis.

By 2030, the fastest rates of population growth and urbanisation will be witnessed in sub-Saharan Africa, followed by India and parts of Southeast Asia (Nagendra et al., 2018). Academic literature (Shoffner et al., 2018) as well as policy documents (UNDP, 2018) have been acknowledging that urbanisation is a global phenomenon with strong environmental sustainability implications and cities have become central to ensuring a sustainable future (Acuto et al., 2018). In ‘Urban Environments in Africa’, Garth Myers deconstructs the criticisms of urban political ecology (UPE) and investigates African environmentalism from different ontological and epistemological points of view.

This article introduces the Journal of Political Ecology Special Section on 'towards a political ecology of applied anthropology.' We provide a brief overview and analysis of the history and application of applied and practicing anthropology. Examining moral and ethical issues related to the application of anthropology, we assess current endeavors and make suggestions for future directions from a political ecology perspective. Introducing five articles that exemplify our approach, we identify common themes and particular contexts that both unify and distinguish each of the contributions. Throughout this introduction, we propose a potential guidepost for a political-ecology informed applied anthropology: any applied anthropology that engages, documents, promotes, and supports cultural diversity, social justice and environmental sustainability is just. Conversely, any applied anthropology that threatens cultural diversity and environmental sustainability is unjust.Key words: applied anthropology, imperialism, political ecology, neoliberalism, ethics
