Political Ecology of Medicinal Plant Use in Rural Nepal: Globalization, Environmental Degradation, and Cultural Transformation

Prior to the advent of biomedicine, rural communities in Nepal relied on phytochemically active compounds in medicinal plants as their primary source of medicine; however, ethnobotanical practices have shifted over time due to economic, environmental, and sociocultural stimuli. Findings from 2016 fieldwork conducted in Dumrikharka, Nepal and Tutung, Nepal are compared to existing literature to describe the political ecology of medicinal plants in rural Nepal. Anthropogenic climate change threatens individual plant species and ecosystem biodiversity. Globalized markets unabated by weak conservation programs place increasing demands on medicinal plants. As indigenous plants become overharvested and more difficult to access, Nepalis incorporate non-indigenous plants into the local pharmacopeia. Novel use of non-indigenous plants illustrates both the dynamic, resilient nature of traditional medicine systems and a loss of biodiversity. Social changes, including outmigration to other countries, notions of modernity, and preference for pharmaceutical drugs, reduce potential candidates to learn and preserve ethnobotanical knowledge. Waterborne pathogens caused by inadequate sanitation infrastructure continue to endanger Nepali populations. The dearth of clinical facilities throughout rural areas, when coupled with the decline ethnobotanical knowledge and traditional healers, poses a gap in healthcare jeopardizing vulnerable, marginalized populations. These factors reinforce the unequal distribution of resources in one of the world’s poorest countries, buttressing power inequalities and economic inequities

Assessing pollen beetle dynamics in diversified agricultural landscapes with reduced pesticide management strategies: Exploring the potential of digital yellow water traps for continuous, high-resolution monitoring in oilseed rape

The European Farm to Fork strategy strives to reduce pesticide use and risk by 50% by 2030, preserving agricultural productivity, biodiversity, and human health. Novel research on crop diversification and new field arrangements, supported by digital technologies, offers sustainable innovations for pest control. This study evaluates digital yellow water traps, equipped with a camera and associated artificial intelligence model for continuous pollen beetle monitoring in diversified agricultural landscapes. Data were collected in oilseed rape from three harvest years (2021-2023) at the experimental site patchCROP, a landscape experiment established to study the effects of spatial and temporal crop diversification measures on yield, ecosystem services, and biodiversity. In patchCROP, crops were planted in smaller, 0.5 ha (72 × 72 m) squares called "patches" with different pesticide management strategies and were compared to surrounding commercial fields. The digital yellow water traps and AI were evaluated and found to be useful for gauging pollen beetle immigration into the crop. Across all years, higher insect pest pressure was recorded in the patches compared to commercial fields but did not necessarily compromise yields. Implementation of pesticide management strategies, including targeted insecticide applications at specific insect pest thresholds, were not associated with reduced yields in patches with flower strips. Future studies should consider examining the role of field size and alternative diversification approaches to fine-tune insecticide reduction strategies at the landscape scale

Examining the integration of transnational people through the lens of spatial mobility: A case study of Estonians living in Finland

Finland and Estonia form a cross-border region in Europe. Unlike other cross-border regions, which share a land border with their neighbor, Finland and Estonia are separated by the Gulf of Finland. The distance is close enough to facilitate regular travel by ferry on a weekly or monthly basis, but for Estonian immigrants living in Finland, daily commutes are unlikely. Given that Finland is the top migration destination for Estonians, the cross-border region of Estonia-Finland poses an interesting case study. In this thesis, the integration and transnationalism of Estonians living in Finland are studied through a spatial mobility lens. First, a theoretical framework is proposed to facilitate empirical research. The framework jointly examines integration and transnationalism by partitioning them into separate domains: social, structural, cultural, civic & political, identity, and spatial. The aim of the framework is to narrow the socio-spatial gap in migration literature, by focusing on the interwoven nature of the social and spatial perspectives. Using data from a comprehensive survey about Estonian immigrants living in Finland, the proposed theoretical framework is operationalized for multiple correspondence analysis (MCA). Three MCA analyses are performed: 1) social integration with host society (Finland), 2) social transnationalism with the sending society (Estonia), and 3) spatial transnationalism between the host society (Finland) and the sending society (Estonia). MCA results show that transnationalism and integration vary both across and within domains. MCA results are connected to one another using correlation analysis and general linear model (GLM) analyses. Correlation analysis and GLM demonstrate that for the study population, integration in the host society and transnationalism with the sending society are inversely associated. This inverse relationship carries over into the spatial domain and can be seen based on which country an immigrant does certain activities (e.g., visiting family, working, accessing healthcare, enjoying leisure time). Immigrants with strong social connections to the host society are more likely to do activities in Finland whereas immigrants with strong social connections to the sending society are more likely to do activities in Estonia. Some immigrants exhibit a multilocal mobility pattern, in which they do activities equally in both Estonia and Finland
