Overview

Deserts, or drylands, cover 47 % of the terrestrial land surface and are home to more than 2 billion people. Despite this, there are an often overlooked environment in the public and global imagination and certainly within geographical education and study. This course explores the what, where and whys of drylands, unearthing the diversity of dryland landscapes and processes and exploring what combination of things sets them apart from different to other places on Earth. In learning about these environments, a wider understanding of Earth Surface processes is also achieved. The variations recorded within drylands record a rich history of climatic and environmental change. The interactions between humans today and drylands involve a range of geohazards and environmental challenges such as adequate access to potable drinking water. You will explore case studies within a range of these human-environmental interactions. The course also includes field and laboratory training to training in research design and sample collection. You will also build skills and confidence in data analysis and data presentation.

Aims

  1. highlight the importance, relevance and uniqueness of dryland environments, which cover 47% of the terrestrial Earth surface, are home to over 2 billion people, and will face substantial challenges under future climate change, including far-reaching consequences outside dryland regions.
  2. provide a detailed understanding of the physical characteristics of drylands, in terms of landscape features and processes and the interactions between processes.
  3. outline and explain understand the nature of past environmental change in drylands over long (Quaternary) timescales in response to changing climatic conditions, and have a critical appreciation of methods used in reconstruction.
  4. provide an introduction to the effects that these environments have on human populations and the impact that humans have on dryland environmental processes.
  5. encourage an interest in the window that geomorphology of Earth provides into interplanetary geomorphology, in particular Martian environments.
  6. provide students with confidence in independent learning, as a vital transferable, employability skill, through guidance of key self-led tasks: (i) an introductory blog post, (ii) field and laboratory investigations and (iii) applying principals learned about the operation of drylands to a class-led discussion about people and drylands (geohazards and environmental resource challenges). [Honing these skills will improve your dissertations]

Knowledge and understanding

  • Demonstrate knowledge of the importance, relevance and uniqueness of dryland environments
  • Demonstrate a detailed understanding of the physical characteristics of drylands and how they have changed over Quaternary timescales

Demonstrate an emerging knowledge of the effects of these environments on human populations and the impacts humans have on dryland environmental processes

Intellectual skills

  • understand the importance of dryland environments as part of the Earth system and the processes and landforms that are characteristic of these regions.
  • identify the ways in which humans interact with dryland environments, including geohazards and pressures on natural resources.

demonstrate a working knowledge of the theoretical basis and practical application of the main techniques used to reconstruct past environmental conditions within drylands

Practical skills

  • field research design, use of field instruments and sample collection

operation of laboratory analytical equipment

Transferable skills and personal qualities

  • information collation, critical reading, evaluation and analysis
  • use of spreadsheets and numeric analytical skills
  • presentation skills for communicating in front of audiences
  • teamwork skills

Employability skills

Analytical skills
Confidence plotting data and performing simple analysis.
Group/team working
In the field and laboratory, working as a team to complete the planning and collection of data
Innovation/creativity
Through the writing tasks (blog post, report and examination) you will hone your creative communication skills.
Oral communication
Discussions in class, and an informal presentation of a case study will develop your confidence and ability in speaking and presenting
Problem solving
The field and laboratory tasks require you to develop how best to collect and analyse data.
Research
Guided reading and encouragement to find wider sources will make you an independent researcher for life, knowing where to go to find reliable information and how to assess its validity.
Written communication
You will develop your skills here via examination essays, a report about field and laboratory data and through a less-formal blog post style.
