Access to clean water, fertile soil, critical metals, and cheap energy is crucial for modern society. However, the unsustainable use of these natural resources is changing the face of our planet at an unprecedented rate. This course builds on the understanding of planet Earth gained in ES1001, and it highlights the work done by earth scientists to solve 21st century resource and environmental challenges. The course investigates the geological processes that generate Earth's "traditional" resources, such as metals and hydrocarbons, and their environmental impact. Equally, students study "new" alternative energies such as geothermal and hydro power, and discuss resource requirements of a "Green New Deal" and potential environmental solutions, such as carbon capture and pollution remediation strategies. There is a fully-funded six-day residential field excursion to the Highlands of Scotland.

Natural disasters are a part of everyday life and may cause significant economic, social, and emotional damage. Natural disasters include earthquakes, volcanic eruptions, tsunamis, meteorite impacts, floods, droughts, wildfires, hurricanes, landslides, and land subsidence. Many natural disasters act at scales so large that humans have no choice but to adapt or suffer the consequences. But in many others, it is mostly human (in)action and behavior before and after the event itself that determines the scale and scope of a disaster. This course connects several recent developments; the ongoing climate change, the increasing connections between economies which cause, for example, the next earthquake in Tokyo or California to have global repercussions, modern media showing the tsunami in Thailand real-time into our homes, refugee flows, and climate conflicts. The course is designed for bachelor students in economics, social sciences, physical geography, earth sciences, history, social geography, environmental sciences, and liberal arts and sciences.

This course explores the many aspects of volcanism on Earth, from the formation of magma below or within the crust to its eruption at the surface, focusing on the volcanism of Mt. Etna, one of the most active volcanoes in the world and a perfect natural laboratory thanks to its peculiar characteristics. The different types of eruptive styles of volcanoes are described and explained within their geological and tectonic contexts, with an additional focus on their impact on the local ecosystem and on human activities in the region, through multiple case studies and in-class discussions. A geological excursion to the Aeolian Islands volcanic archipelago provides an opportunity to further explore modern volcano monitoring techniques, with a particular focus on geophysical and geochemical methods, and of implementing data collection into a research project. This course provides students, through a combination of classroom and field-based learning, with knowledge on geophysical, geochemical and petrological monitoring methods of active volcanoes, on the techniques and strategies for analyzing and modeling monitoring data and on their use for the purpose of assessing volcanic hazard. In addition to the lectures, the students are engaged in practical exercises on instrumentation and modeling methods. The field trips and site visits also provide context to devote specific attention to the impact of volcanic eruptions on human activities and life, unveiling the close interplay between man and volcanoes around the world and throughout history.
