For a foundation in the discipline, start with Geography: A Very Short Introduction, Human Geography: A Very Short Introduction, Prisoners of Geography, The Invention of Nature, Adventures in the Anthropocene, Why Geography Matters. These books help you move between geographical method, human geography, geopolitics, environmental change and the history of geographical thought.
For video-led enrichment, use Oxford Geography, Royal Geographical Society, NASA Earth Observatory, Our Changing Climate, The Economist. The stronger use of these channels is not passive watching; make notes on evidence, scale, uncertainty and alternative explanations.
For audio, try Ask the Geographer, Geographical Podcast, GeogPod, The Inquiry, Geography Is Everything. Podcasts work best when you turn one episode into a follow-up reading question or a case study you can analyse.
For practical skills, use Geographic Information Systems (GIS) Specialization, Getting Started with QGIS, Getting started with the climate crisis, Fundamentals of Remote Sensing, Nature-based Solutions to Global Challenges Foundation Course. We recommend building one small map-led or data-led project from these courses, because Oxford Geography includes techniques, fieldwork and dissertation work.
