Internal Ecologies and the Limits of Local Biologies: A Political Ecology of Tuberculosis in the Time of AIDS

Landscapes of inequities, structural racism, and disease during the COVID-19 pandemic: Experiences of immigrant and racialized populations in Canada

The COVID-19 pandemic has disproportionately affected immigrant and racialized communities globally and revealed another public health crisis - structural racism. While structural racism is known to foster discrimination via mutually reinforcing systems, the unevenness of COVID-19 infections, hospitalizations, and deaths across societies has precipitated attention to the impacts of structural racism. Research highlights the inequitable burden of COVID-19 among immigrant and racialized groups; however, little is known about the synergistic impacts of structural racism and COVID-19 on the health and wellbeing of these groups. Fewer studies examine how structural racism and COVID-19 intersect within neighbourhoods to co-produce landscapes of disease exposure and management. This article examines the pathways through which structural racism shapes access, use, and control of environmental resources among immigrant and racialized individuals in the neighbourhoods of the Peel Region and how they converged to shape health and disease dynamics during the height of Canada's COVID-19 pandemic. Findings from in-depth interviews reveal that mutually reinforcing inequitable systems created environments for COVID-19 to reinscribe disparities in access, use, and control of key resources needed to manage health and disease, and created new forms of disparities and landscapes of inequality for immigrants and racialized individuals. We close with a discussion on the impacts for policy and practice.

Examining County-Level Associations between Federally Qualified Health Centers and Sexually Transmitted Infections: A Political Ecology of Health Framework

Federally Qualified Health Centers (FQHCs) are the largest providers of healthcare for sexually transmitted infections (STIs) in medically underserved communities in the United States (US). Through the Affordable Care Act (ACA), FQHCs have grown in number, but the impact of this growth on STIs is poorly understood. This ecological study seeks to quantify the association between FQHCs and STI prevalence in all US counties. Variables were described utilizing medians and interquartile ranges, and distributions were compared using Kruskal-Wallis tests. Median rates of chlamydia in counties with high, low, and no FQHCs were 370.3, 422.6, and 242.1 cases per 100,000 population, respectively. Gonorrhea rates were 101.9, 119.7, and 49.9 cases per 100,000 population, respectively. Multivariable linear regression models, adjusted for structural and place-based characteristics (i.e., Medicaid expansion, social vulnerability, metropolitan status, and region), were used to examine county-level associations between FQHCs and STIs. Compared to counties with no FQHCs, counties with a high number of FQHCs had chlamydia rates that were an average of 68.6 per 100,000 population higher (β = 68.6, 95% CI: 45.0, 92.3) and gonorrhea rates that were an average of 25.2 per 100,000 population higher (β = 25.2, 95% CI: 13.2, 37.2). When controlled for salient factors associated with STI risks, greater FQHC availability was associated with greater diagnosis and treatment of STIs. These findings provide empirical support for the utility of a political ecology of health framework and the critical role of FQHCs in confronting the STI epidemic in the US.

Towards an integrated theoretical framework for understanding water insecurity and gender-based violence in Low-and middle-income countries (LMICs)

Disparities in access to basic needs and resources such as water is largely borne out of power imbalance across scale. In examining these power dynamics in the context of health inequalities, scholars have deployed Feminist political ecology analytical framework to situate gender and other forms of vulnerability as emerging from unequal power relations, and political ecology of health to emphasise the health implications of inherent relational power in the distribution of resources. Although appealing, the two theoretical frameworks over time have proven to be limiting in the study of intersectional vulnerabilities such as gender-based violence and water insecurity which reflect multiple dimensions of unequal power structures. This study expands the theoretical space for the study of inequalities in health geography by demonstrating the utility of incorporating feminist political ecology with political ecology of health to form an integrated theoretical framework - Feminist Political Ecology of Health (FPEH). This proposed theoretical framework gives guidance for engaging with a suite of questions and methods related to multifaceted problems such as water insecurity and gender based-violence. The paper highlights these theoretical issues and then discusses how FPEH can enrich research on water security and gender-based violence in Low-and middle-income countries (LMICs).

Climate change, women's workload in smallholder agriculture, and embodied political ecologies of undernutrition in northern Ghana

The burden of child undernutrition across Africa remains extraordinarily high. Among children under age five, chronic and acute undernutrition is responsible for more ill-health than any other cause. While climate change exacerbates the multiple burdens of undernutrition, we know very little about the embodied effects on women's workload in agriculture and implications for feeding practices, especially for infants whose nutrition depends on mothers' time. In this article, political ecologies of health, with its nested, place-based analysis, is used as a framework to address this knowledge gap. The study took place in Ghana's Upper West Region, a semi-arid and resource-poor setting with higher undernutrition rates. In-depth interviews were conducted with smallholder farmers (n = 33) whose infants have sub-optimal growth, and key informants (n = 7) with expertise in nutrition and health. Findings from the study demonstrate how climate change puts pressure on women's productive time, leading to poor child feeding practices and undernutrition. Ultimately, the article argues that there are hidden impacts of climate change on undernutrition. Global undernutrition interventions should therefore move beyond biomedical solutions to address these hidden impacts, some of which are social, gendered, and structural in nature.

Performativity and a microbe: Exploring Mycobacterium bovis and the political ecologies of bovine tuberculosis

Mycobacterium bovis, the bacterium responsible for causing bovine tuberculosis (bTB) in cattle, displays what I call ‘microbial performativity’. Like many other lively disease-causing microorganisms, it has an agency which is difficult to contain, and there is a need for fresh thinking on the challenges of dealing with this slippery and indeterminate microbe. As a practising veterinary scientist who side-stepped mid-career into a parallel training in the social sciences to view bTB from an alternative perspective, I create an interdisciplinary coming-together where veterinary science converges with a political ecology of (animal) health influenced by science and technology studies (STS) and social science and humanities scholarship on performativity. This suitably hybridized nexus creates a place to consider the ecologies of a pathogen which could be considered as life out of control. I consider what this means for efforts to eradicate this disease through combining understandings from the published scientific literature with qualitative interview-based fieldwork with farmers, veterinarians and others involved in the statutory bTB eradication programme in a high incidence region of the UK. This study demonstrates the value of life scientists turning to the social sciences to re-view their familiar professional habitus—challenging assumptions, and offering alternative perspectives on complex problems.

HIV as social and ecological experience

The spread and varied impacts of the HIV/AIDS epidemic demonstrate the complex and reciprocal relationships between the socio-political and biophysical dimensions of human health. Yet even with increasing research and policy attention there remain critical gaps in the literature on how HIV-positive households manage health through their engagement with social and ecological systems. This is particularly urgent given improvements in the global response to the epidemic, whereby expanded access to antiretroviral therapy has extended the possibility for survival for years or decades. Because many HIV-positive families and communities in the Global South remain dependent upon a diverse set of resources to generate income and meet subsistence needs, the impacts of disease must be understood within a mix of social processes, including the maintenance of land and collection of natural resources. Similarly, biophysical systems disrupted by HIV/AIDS vary depending upon resource use and locally-specific dynamics that influence opportunities for agrarian production. This paper reports on the findings from a structured survey completed in three communities in northeast South Africa in 2013 that is integrated with focus group discussions and qualitative interviews conducted from 2012-2016. We concentrate upon the diverse ways that individuals and families experience HIV through livelihood systems that are reliant on economic and natural resources. Because the access and use of these resources are mediated by existing social, cultural, and institutional systems, as well as historical spatial economies, we analyze how this produces differential lived experiences for HIV-positive individuals and households in the age of expanded access to antiretroviral therapy.

"What the mind does not know, the eyes do not see". Placing food allergy risk in sub-Saharan Africa

Policy makers and health geographers are increasingly intrigued by the global rise of chronic disease. While current engagement coalesce around cardiovascular disease, cancers, chronic respiratory disease, and diabetes, very little attention has been given to other important chronic conditions: e.g., allergic disease. Concerns about how health is shaped by context and experienced in place can provide important insights to understand the trajectory of allergic disease and inform policy especially in developing countries experiencing an epidemiologic transition. Using Ghana as a case study. this paper draw on theories of political ecology of health to enhance our understanding of how individual (e.g. care seeking behaviours), sociocultural (e.g. lack of education and awareness), health system (e.g. absence of logistics) and policy environments (e.g. absence of policy) influence the ways in which food allergy is perceived, diagnosed and managed. These findings highlight the need for decision makers to target structural factors that impede access to and utilization of healthcare, diagnostic practices, as well as food allergy coping and management strategies. Moreover, the findings highlight the need for a global health agenda that pays critical attention to place-based factors in the construction of emerging health risks.

"Ne nnipadua mmpe" (the body hates it): Exploring the lived experience of food allergy in Sub-Saharan Africa

Allergic diseases have closely followed the rise of non-communicable diseases (NCDs) especially in western societies. As prevalence of NCD is increasing in sub-Saharan Africa (SSA), researchers are hinting that the same future may hold for (food) allergic disease in this world region. Already, researchers are beginning to record prevalence, though with little attention to the social experience of individuals and parents with food allergic children. This paper presents the first qualitative analysis of the daily realities of adults and parents of children with allergies in SSA using Ghana as a case study. Drawing on political ecology of health, this study contextualizes the psychological (e.g. anxiety and fear), social (e.g. stigmatization, social exclusion), and economic (e.g. impact on work & household expenditures) wellbeing of affected persons within the broader sociocultural environment. By exploring the sociocultural environment, the results provide insights into the likely structures (e.g. the lack of familiarity, absence of local discursive repertoire on food allergy, infrastructure deficit) which interact to shape anxiety, and social exclusion of people with allergy. The case study provides evidence suggesting food allergies do have a global reach, and policy makers must heed the message to integrate food allergy into the broader chronic disease prevention agenda.

Political Ecologies of Global Health: Pesticide Exposure in Southwestern Ecuador's Banana Industry

Pesticide exposure in Ecuador's banana industry reflects political economic and ecological processes that interact across scales to affect human health. We use this case study to illustrate opportunities for applying political ecology of health scholarship in the burgeoning field of global health. Drawing on an historical literature review and ethnographic data collected in Ecuador's El Oro province, we present three main areas where a political ecological approach can enrich global health scholarship: perceptive characterization of multi-scalar and ecologically entangled pathways to health outcomes; critical analysis of discursive dynamics such as competing scalar narratives; and appreciation of the environment-linked subjectivities and emotions of people experiencing globalized health impacts. Rapprochement between these fields may also provide political ecologists with access to valuable empirical data on health outcomes, venues for engaged scholarship, and opportunities to synthesize numerous insightful case studies and discern broader patterns.
