Aims

To provide a knowledge and understanding of

How humans impinge on the biosphere through an examination of the impact of key anthropogenic stressors arising from resource exploitation and use, agriculture and urbanisation on selected ecosystems and biomes.
Methods and approaches - from molecular to community level - used in the assessment and prediction of human impacts on ecosystems.

    Learning outcomes

    Students should gain an understanding of:

    • The impact of natural resource exploitation and pollution on populations and communities through the study of important human activities, specifically resources utilisation (metal ores from mining); agriculture; urbanisation; transport
    • Methods and approaches used in the assessment and prediction of anthropogenic impacts on key ecosystems and biomes

    And be able to:

    • Appreciate the importance of connecting and integrating knowledge regarding human impacts, including on the whole biosphere and not only one sector
    • Appreciate the importance of field and laboratory studies in understanding and solving environmental problems arising from human activities
    • Critically appraise and discuss research literature regarding contemporary and controversial issues related to human impacts on the environment

    Syllabus

    •       Introduction: Population pressure and resource utilization; pollutants of land, water and air; acute and chronic pollution; standards and guidelines

    •       Environmental impact of mineral pollutants - metals and radioactivity: the legacy and risks of radioactive pollutants; bioaccumulation and toxicity; treatment and bioremediation of inorganic pollutants with particular reference to radionuclides and heavy metals.

    •       Environmental Impact of agriculture: Impacts on biodiversity; potential conflicts with productivity; chemical inputs and the ‘green revolution’; irrigation and salinization

    •       Urbanisation: Impact of sewage on urban water quality and ecology; role of planning in pollution control and enhancing biodiversity; urbanisation and terrestrial biodiversity

    •       Environmental impact of air pollution from road transport: Sources and monitoring; air pollutants from transport; impact of ozone and nitrogen dioxide on vegetation and food security

    Employability skills

    Analytical skills
    The literature review requires analysis of primary and secondary (reviews) sources and critically evaluate experimental and field data.
    Innovation/creativity
    The literature review requires the students to generate a case study of a human derived pollution incident therefore innovation is needed in the research ideas they identify and present.
    Project management
    Organise and produce literature review to specified deadline.
    Oral communication
    Students provide verbal answers to prepared tasks and ask questions during workshops.
    Problem solving
    Questions are asked throughout the course including during the workshops for each topic, some of which require problem solving.
    Research
    Required for e-learning questions and literature review.
    Written communication
    Individual e-learning questions and literature review assignment plus essay questions during examination.

    Assessment methods
