The book describes how microscopic particles in the air—born of combustion, dust storms, agriculture, and urban life—travel from the atmosphere into soils, water, plants, and food chains, reshaping ecosystems and human health. From Sky to Soil maps this ecological journey, explaining the physics and chemistry of particulate matter (from coarse dust to ultrafine nanoparticles), the meteorological currents that ferry particles across regions, and the biogeochemical consequences of their deposition. Drawing on decades of fieldwork across the Indo-Gangetic plains, Himalayan foothills, and Southern Africa, the book links urban emissions to rural impacts: diminished crop yields, altered soil microbiomes, pollinator declines, and contaminated food systems. It exposes underappreciated threats—particulate-bound pesticides and pathogens, heavy-metal-laden urban dust—and quantifies risks to communities, particularly children in small cities. Yet this is not a catalogue of despair. Grounded in rigorous science, the volume offers practical pathways to restoration: phytoremediation, urban greening, policy levers, and design strategies that build resilient airscapes. Chapters synthesize mechanistic insights, regional case studies, and actionable solutions for researchers, educators, planners, and policymakers. Clear, evidence-rich, and urgent, From Sky to Soil bridges disciplines to show that cleaning our skies is essential to healing our soils, protecting food security, and preserving biodiversity. For anyone committed to sustainable cities, healthy ecosystems, and informed climate action, this book is an indispensable roadmap from knowledge to action.
