요약The gap between the formal recognition of the human right to a healthy environment and its on-the-ground realization persists due to multiple factors, including critical limitations in how we quantify and make environmental injustices spatially visible. To address this analytical gap, I develop and apply a multi-scalar data-driven framework integrating gridded spatial analysis, statistical modeling, climate projections, and socioeconomic population projections. This work provides a quantitative approach for translating abstract rights principles into empirical assessments of environmental harm and exposure patterns.First, this research presents a globally harmonized, spatially explicit diagnostic of present-day environmental rights across five dimensions: clean air (PM2.5), safe water (sanitation access), a safe climate (heat stress), healthy food (food insecurity and pesticide exposure), and biodiversity (Biodiversity Intactness Index). Using gridded data at 10km resolution, the analysis reveals that over 99% of the global population (7.6 billion people) experiences at least one environmental condition threatening their rights, while over 45% (3.4 billion) face three or more simultaneous threats. These multi-threat hotspots exhibit a stark geography of inequality, disproportionately concentrated in the Global South and systematically affecting marginalized communities including Indigenous peoples and refugees within nations. The analysis further reveals significant transboundary effects, where environmental burdens are displaced through global trade systems, creating a fundamental accountability challenge for rights realization.Second, to address a critical data gap that limits risk assessment for vulnerable populations, this work develops the first spatially explicit, gridded dataset mapping the global agricultural workforce from 2000-2100. Using Generalized Additive Mixed Models (GAMMs) and integrating socioeconomic variables including GDP per capita, population density, and agricultural land use, the projections are made consistent with all five Shared Socioeconomic Pathways (SSPs). The results reveal profound regional divergence, including a projected 44% increase in Sub-Saharan Africa's agricultural workforce by 2050 versus a 10.6% decline in East Asia & Pacific. This dataset enables detailed spatial risk assessments for a population critical to global food security but previously invisible to large-scale environmental analysis.Third, integrating this novel workforce dataset with hourly Wet Bulb Globe Temperature (WBGT) projections, the research quantifies how climate change will erode agricultural workdays through extreme heat exposure. This represents the first analysis to combine hour-by-hour heat stress calculations with spatially explicit agricultural workforce projections to assess actual working time losses. By 2050, workers exposed to over 100 days of unsafe heat annually are projected to nearly double from 359 to 663 million. Under SSP5-8.5, 11% of a standard 9am-5pm workday will be lost globally to unsafe conditions. The hourly analysis reveals that common adaptation strategies, such as shifting work to cooler dawn and dusk hours, are becoming physiologically obsolete in tropical and coastal regions-a constraint overwhelmingly overlooked in current National Adaptation Plans.By integrating global-scale environmental diagnostics with detailed projections for a highly exposed population, this dissertation contributes empirical tools and methodological approaches that can inform policy alignment with the lived realities of those most at environmental risk. This work builds upon and complements the extensive knowledge developed by affected communities, providing scientific support for the broader struggle to realize environmental justice in practice.
