Detailed case studies notes on coastal landscapes beyond the UK (one of the spec point on AQA Geography A level syllabus). This includes Mekong delta and the Dutch coast, allowing comparisons in different coastal management strategies in countries at different levels of development.
Case studies of contrasting coastal
landscapes beyond the UK
,Specification
Case study of a contrasting coastal landscape beyond the UK to illustrate and analyse how it presents
risks and opportunities for human occupation and development and evaluate human responses of
resilience, mitigation and adaptation.
The specification asks us to focus on two key areas in this case study:
1. The risks and opportunities for humans in this coastal environment; and
2. The way that humans have responded to the risks in terms of mitigating the risks,
adapting to them, and building resilience from them. We also need to assess how
successful (or otherwise) those
You only need to have one such case study, but this booklet will cover two contrasting
ones, which you can either select from, or learn both!
Specification Themes and Theory
OPPORTUNITIES AND RISKS
Let us first consider the risks and opportunities which might, in general, exist for coastal areas.

RESILIANCE, MITIGATION AND ADAPTATION
These three broad categories all refer in somewhat different ways to the ways that coastal
communities can respond to the risks that presented by coastal areas. Although they each
have a different emphasis, it should be emphasized that they are not easy to delimit from
one another, are used differently and inconsistently in the literature, and are perhaps best
thought of in terms of three overlapping circles on a venn diagram, as shown below. This
then presents challenges for how you might structure an essay, but also evaluative
opportunities if you are being asked to consider differences between these categories.
