University professor and TV documentary presenter Iain Stewart gave a lecture on natural disasters to students and teachers from 11 schools.
Prof Stewart described how human populations add to risks posed by natural disasters such as landslides, volcanic eruptions and earthquakes.
The inaugural lecture of the Geolincs network was hosted by Bourne Grammar School (BGS) and attended by pupils and teachers from across the region, including Spalding and Market Deeping.
Geolincs was set up by BGS geography teacher Aidan Hesslewood for the region’s educators to share ideas about the changing landscape of geography education. It now seeks to support the young geographers too.
Mr Hesselwood said Prof Stewart helped students understand how “natural” hazards have become even more hazardous because of our actions as humans, whether that’s populations increasingly located near major fault lines, or the changes in the nature of the risk itself.
He said: “For example, people have always lived near areas prone to tsunamis, but rather than being faced with a wall of water coming towards you as happened in the past, people are now faced with a wall of water full of buildings, cars, fridges etc.”
Mr Hesselwood said Prof Stewart, director of the Sustainable Earth Institute at Plymouth University, also underlined the world’s need to have people trained in geography and geology to tackle such major issues.
l Earlier this year the BGS geography department was recognised by the Geographical Association as a centre of excellence nationally.
