Title: The ecological and evolutionary consequences of systemic racism in urban environments
Urban areas are dynamic ecological systems defined by interdependent biological, physical, and social components. The emergent structure and heterogeneity of urban landscapes drives biotic outcomes in these areas, and such spatial patterns are often attributed to the unequal stratification of wealth and power in human societies. Despite these patterns, few studies have effectively considered structural inequalities as drivers of ecological and evolutionary outcomes and have instead focused on indicator variables such as neighborhood wealth. In this analysis, we explicitly integrate ecology, evolution, and social processes to emphasize the relationships that bind social inequities—specifically racism—and biological change in urbanized landscapes. We draw on existing research to link racist practices, including residential segregation, to the heterogeneous patterns of flora and fauna observed by urban ecologists. In the future, urban ecology and evolution researchers must consider how systems of racial oppression affect the environmental factors that drive biological change in cities. Conceptual integration of the social and ecological sciences has amassed considerable scholarship in urban ecology over the past few decades, providing a solid foundation for incorporating environmental justice scholarship into urban ecological and evolutionary research. Such an undertaking is necessary to deconstruct urbanization’s biophysical patterns and processes, inform equitable and anti-racist initiatives promoting justice in urban conservation, and strengthen community resilience to global environmental change.  more » « less

  1. Abstract We ask how environmental justice and urban ecology have influenced one another over the past 25 years in the context of the US Long-Term Ecological Research (LTER) program and Baltimore Ecosystem Study (BES) project. BES began after environmental justice emerged through activism and scholarship in the 1980s but spans a period of increasing awareness among ecologists and environmental practitioners. The work in Baltimore provides a detailed example of how ecological research has been affected by a growing understanding of environmental justice. The shift shows how unjust environmental outcomes emerge and are reinforced over time by systemic discrimination and exclusion. We do not comprehensively review the literature on environmental justice in urban ecology but do present four brief cases from the Caribbean, Africa, and Asia, to illustrate the global relevance of the topic. The example cases demonstrate the necessity for continuous engagement with communities in addressing environmental problem solving.

  2. Abstract Detecting and understanding disturbance is a challenge in ecology that has grown more critical with global environmental change and the emergence of research on social–ecological systems. We identify three areas of research need: developing a flexible framework that incorporates feedback loops between social and ecological systems, anticipating whether a disturbance will change vulnerability to other environmental drivers, and incorporating changes in system sensitivity to disturbance in the face of global changes in environmental drivers. In the present article, we review how discoveries from the US Long Term Ecological Research (LTER) Network have influenced theoretical paradigms in disturbance ecology, and we refine a framework for describing social–ecological disturbance that addresses these three challenges. By operationalizing this framework for seven LTER sites spanning distinct biomes, we show how disturbance can maintain or alter ecosystem state, drive spatial patterns at landscape scales, influence social–ecological interactions, and cause divergent outcomes depending on other environmental changes.

  3. Suspended infrastructure of megaprojects marks Latin American landscapes. However, little research has attended to the social-environmental and political-ecological processes of such infrastructure. Moreover, while social conflict often accompanies infrastructure development, our research emphasizes citizen contestation of the suspension and dynamic spatial unevenness as a claim on the state to complete the project. This study examines Colombia’s largest suspended irrigation infrastructure, the Tolima Triangle Irrigation District, through a combined political ecology and social-ecological systems framework. Results of integrated analysis show how the suspension drives differentiation in resource use and the social responses of individuals and communities to deepening disparities. In turn, public contestation of suspended infrastructure drives future prospects for the Tolima megaproject. Data is drawn from field research conducted for one year in 2018-2019. Mixed methods included semi-structured interviews, environmental assessment techniques, household surveys, and ethnographic participant observation. The research demonstrates that suspended infrastructure is neither a politically neutral, merely passive backdrop nor void of transformation but rather is comprised of contested processes rooted in the expanding social-environmental and political-ecological unevenness of development. Our findings contribute to the research on infrastructure suspension and development, and they are set within a broader body of scholarship on irrigation and political ecology of Latin American countries.

  4. This article advances geographic scholarship about conservation and protected areas (PAs) through a focuson biocultural geographies. Biocultural geographies derive from relationships between heterogenousIndigenous stewardship practices, biological diversity, and trans-scalar multidimensional social, political, andecological processes. The concept brings together insights from political ecology and biocultural conservationto address the interplay between environmental governance, cultural change, and biodiversity. We drawfrom collaborative, transdisciplinary research with Siona, Siekopai, and Cofan Indigenous communities inthe northern Ecuadorian Amazon, a site of global importance for its biodiversity and cultural heritage. Thisis also a region of rapid and extensive social-ecological change driven by expanding agricultural frontiers,intensifying extractive industries, and new infrastructure development for regional integration. It is from thiscontext that we call for a timely and critical conversation between human–environment geographers and thefield of biocultural conservation, two approaches that have reshaped thinking about PAs and the role ofIndigenous stewardship in an era of accelerating global challenges to social-ecological well-being. Data forour analysis derive from a multiyear study that investigates strategies used to ensure social-ecological well-being in the face of change. Our findings show that Siona, Siekopai, and Cofan stewardship sustains thebiological diversity that characterizes many Amazonian PAs through locally adapted institutions based onknowledge, innovation, and practices they collectively hold. Such stewardship advances self-determinationthat challenges conventional conservation and PA models by centering Indigenous territorial governance.

    Human-wildlife interactions, including human-wildlife conflict, are increasingly common as expanding urbanization worldwide creates more opportunities for people to encounter wildlife. Wildlife-vehicle collisions, zoonotic disease transmission, property damage, and physical attacks to people or their pets have negative consequences for both people and wildlife, underscoring the need for comprehensive strategies that mitigate and prevent conflict altogether. Management techniques often aim to deter, relocate, or remove individual organisms, all of which may present a significant selective force in both urban and non-urban systems. Management-induced selection may significantly affect the adaptive or non-adaptive evolutionary processes of urban populations, yet few studies explicate the links among conflict, wildlife management, and urban evolution. Moreover, the intensity of conflict management can vary considerably by taxon, public perception, policy, religious and cultural beliefs, and geographic region, which underscores the complexity of developing flexible tools to reduce conflict. Here, we present a cross-disciplinary perspective that integrates human-wildlife conflict, wildlife management, and urban evolution to address how social-ecological processes drive wildlife adaptation in cities. We emphasize that variance in implemented management actions shape the strength and rate of phenotypic and evolutionary change. We also consider how specific management strategies either promote genetic or plastic changes, and how leveraging those biological inferences could help optimize management actions while minimizing conflict. Investigating human-wildlife conflict as an evolutionary phenomenon may provide insights into how conflict arises and how management plays a critical role in shaping urban wildlife phenotypes.
