Description - summary of the module content

Module description

The search for knowledge about the impact of humans on the global environment has grown in importance as population growth intensifies the demand for resources such as energy and water. A growing body of scientific evidence is highlighting the fragile future of biodiversity, water resources, food security, and natural carbon stocks under global climate change. Our changing environment presents a fascinating and urgent set of challenges and opportunities for today’s practitioners, policy makers and researchers. This module will introduce you to the concept of the “grand challenges” in environmental science by providing a thought-provoking overview of the main issues facing environmental scientists today. The module requires you to have an interest in environmental issues and sustainability. It is suitable for specialists and non-specialists alike. It is a highly interdisciplinary module that can be taken by any student at the Penryn Campus.

Module aims - intentions of the module

At the beginning of this millennium, eight “grand challenges” for environmental scientists were highlighted by the US National Science Foundation. These eight areas were chosen because they offer the potential for a timely, major scientific breakthrough of practical importance to benefit humankind. The challenges are:

  • Understanding global biogeochemical cycles
  • Biodiversity and ecosystem functioning, to include evaluation of ecosystem goods and services
  • Climate variability over varying timescales
  • Hydrological forecasting related to freshwater provision and hydrological hazards
  • Infectious disease and epidemiological risk
  • Natural resource use: from international treaties to local policies
  • Land use dynamics and changes in global land cover
  • Life cycles of materials in the environment (e.g. pesticides, plastics): sustainable use of such resources

This module will address these grand challenges through delivery of an innovative and truly interdisciplinary series of lectures, interactive seminars, laboratory sessions and field trips, that are aimed at giving you an understanding of environmental science issues with truly global importance. You will have the opportunity to take part in a debate on a key subject of relevance to the discipline.

Module laboratory sessions and field trips may have to be moved online/replaced in the event of continued COVID-19 lockdown/social distancing rules.

This module is team taught, with several members of staff contributing to both lectures and seminars, and will involve elements of research undertaking by those staff. Moreover, you are encouraged to undertake enquiry-led learning, specifically through the discussion sessions and will also be guided towards relevant key research papers.

Employability: This module will help you to develop and extend skills to strengthen employability potential, such as critical analytic thinking and the communication of ideas through the application to a range of contemporary global challenges.

Syllabus plan

Syllabus plan

The module will comprise various sessions of 1 hour each. While the exact topics covered may vary from year to year, it is envisaged that the module will cover all or some of the following topics:

  • Module introduction and overview – the big ideas in environmental science
  • Global climatologies – in the past and in the future – the Anthropocene
  • Air quality
  • Water as a resource (including water quality)
  • Global vegetation systems and land use/cover change
  • Biodiversity and Earth’s life support systems
  • The media and the environment – how the public understand environmental issues
  • Climate change and human responses to it including climate scepticism
  • Agri-environments, histories of pesticide use and future practices
  • Living landscapes, ecosystem valuation
  • Health and epidemiology
  • Sustainable energy
  • Natural risks, hazards, and extreme weather events

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. The mark given for a re-assessment taken as a result of referral will count for 100% of the final mark and will be capped at 40%.
