Geography Matters

In mid January 2025 President Trump announced that he wanted to take back control of the Panama Canal. We might ask what this is all about and the part answer is that the US originally built and operated the canal then handed it back to Panama in 1979. Cutting off journeys round south America it accounts for about 30% of US container trade. But the Panama canal is part of a much bigger picture. Ov...

In early January 2025 President Trump shocked the world by announcing that the US wanted to buy Greenland. The Danish government said it was not for sale. But this is not the first time that the USA has attempted to buy Greenland. It has made previous offers first in 1867 after it bought Alaska, then again in 1946 when it offered Denmark $100 million, and President Trump made an earlier offer in 2...

Drinking water is crucial for human survival and for agriculture. But, as the world's population grows and pressure on resources increases, water is increasingly becoming a scarce commodity. Conflicts over water have a long history and in recent decades more and more countries want to dam rivers to control the flow, provide water for agriculture and generate power. But activities upstream have a b...

People have always migrated from place to place or country to country whether it is to escape hunger, drought, war or persecution or to search for stability, security or better living standards. The nineteenth century was a century of large scale migration, both within Europe, and from Europe to the New World - the USA and Canada. The Irish potato famine saw millions of people migrate to avoid sta...

Borders are extremely important, both in terms of national sovereignty and for human mobility and limits to it. In nomadic societies people often moved relatively freely with the seasons over long distances but borders have become much more important with the evolution of nation states in the last few hundred years. Borders today are marked on maps and sometimes marked on the ground with border fe...

The term 'postcode lottery' became popular in Britain in the late 1990's to refer to the variations in health care from one area or region to another. It suggested that variations or inequalities in health care provision or drug availability or treatment were essentially random and varied depending on where you lived. Subsequently the term has been widened to refer to variations in educational pro...

The Falkland Islands are very remote: 8,000 miles south of London, 700 miles north of the northern most part of Antarctica and 300 miles east of Argentina. Only discovered in 1760 by a British sailor, then variously settled and occupied by British, French and Spanish garrisons, the islands were claimed for the British crown in 1832. But, given their proximity, Argentina has, not surprisingly, long...

Svalbard, or Spitzbergen, as it used to be called, is an archipelago in the Arctic ocean about midway between the north of Norway and the North Pole and midway between Greenland to the West and the islands of Novaya Zemblya in northern Russia. 60% of it is covered with glaciers and it has about 3000 people. Its a place most people have never heard of, but it has considerable geographical and strat...

This is a taster for the Geography Matters podcast series. It explains why geography matters for understanding the world and how it intersects with history and with economics, politics, society and the environment. Everything happens in particular places and particular times. Geography looks at where and why and history looks at when and why. The series is presented by Chris Hamnett, emeritus prof...
