Define Environmental Geoscience
Define Environmental Geoscience
Environmental Geoscience is an interdisciplinary field that applies principles of geology, geography, chemistry, biology, and physics to study the Earth's environment and its interaction with human activities. It focuses on understanding how natural processes-such as the movement of water, the formation of soils, and atmospheric dynamics-affect the environment, and how human actions influence these processes.

Study Notes
Introduction to Environmental Geoscience
- Environmental Geoscience is a multidisciplinary field combining geology, geography, chemistry, biology, and physics
- It studies Earth's environment and its interaction with human activities
- It focuses on how natural processes like water movement, soil formation, and atmospheric dynamics influence the environment
- Human actions also influence these processes
Environmental Issues
- Events or processes threatening the state of environments, leading to degradation
- Traditionally categorized into natural and human events/processes
- Human activities have greatly impacted Earth’s geological environment
- Causes and effects of these processes are increasingly intertwined
Pollution and Waste Management
- Focuses on pollutants in air, soil, and water
- Examines sources, transport, and effects of pollutants
- Seeks strategies to mitigate pollutant impacts
- Environmental issues are often global or local in nature
Resources
- Sustainable use of natural resources like fossil fuels, minerals, water, and renewable energy
- Study of natural resource consumption and production impacting climate, biodiversity, and pollution
- Global material extraction of main material categories (1970–2024)
Natural Hazards
- Analysis of risks and impacts of earthquakes, volcanoes, floods and landslides
- Development of mitigation strategies for these hazards
Environmental Geoscience as a Multidisciplinary Concept
- Environmental Geoscience requires both interdisciplinary science and multidisciplinary approaches to understand Earth's physical environment, nature, and living things; humans
- Humans are an outgrowth of the physical structure of the planet and an engine of its global cycles
Environmental Geoscience in a Multidisciplinary, Political World
- The course discusses many aspects of the relationship between human activity, environmental resources, and global issues
- Anthropocene conditions are covered, including the highest atmospheric CO2 concentration, global mean temperature increases, and increased extinction rates.
Summary
- Environmental Geoscience systematically studies the Earth and its interactions
- Earth's environment has been significantly impacted by industrial processes, resource extraction, and waste generation
- Sustainability issues are increasingly complex
- Geoscientists play a crucial role in finding solutions for planetary sustainability
Spot the Environmental Geoscience
- Geologists are skilled at understanding landscapes and their evolution
- The various case studies show how surface processes and human activity affect environments
- Students are to identify possible environmental processes, challenges and solutions based on the images and locations displayed
