Key Terms for Issue Evaluation

📖 Key Terms for Issue Evaluation

stakeholder — Any individual, group or organisation that has an interest in or is affected by a geographical issue or decision. Different stakeholders have different priorities, values and levels of power. Identifying stakeholders and explaining their perspectives is essential for Level 3 answers.

trade-off — The sacrifice of one benefit in order to gain another. In geographical decisions, there are almost always trade-offs: a sea wall protects properties but damages the beach; a road reduces journey times but divides a community; a reservoir provides water but floods a valley. Understanding trade-offs shows you recognise that geographical decisions involve real choices, not free improvements.

sustainability — Meeting the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland Commission, 1987). In Issue Evaluation, a sustainable option typically involves managing natural processes rather than fighting against them, has low long-term maintenance costs, creates environmental value, and considers the needs of future generations alongside present ones.

primary data — Data collected first-hand by the researcher: field measurements, questionnaires, interviews, observations, photographs taken personally. Primary data is directly relevant to your specific question but can be expensive, time-consuming and limited in scope.

secondary data — Data already collected by someone else: government statistics, published reports, academic studies, newspaper articles, maps, satellite images. Most of the sources in the pre-release booklet are secondary data. Secondary data is often wider in scope than primary data but may be out of date, produced for a different purpose, or have limitations in methodology.

managed retreat (coastal) — A coastal management strategy in which natural erosion and/or flooding is allowed to proceed, and land-uses or structures are relocated away from the coast. Properties may be demolished or relocated; agricultural land is flooded. Managed retreat creates intertidal habitat (salt marsh, mudflat) and works with natural processes. It is generally considered more sustainable than hard engineering but is politically difficult because it directly affects property owners.

hard engineering (coastal) — Artificial structures built to resist or absorb wave energy: sea walls, rock armour revetments, groynes, offshore breakwaters. Hard engineering directly protects the defended shoreline but can accelerate erosion on adjacent undefended coasts, is expensive to maintain, and must eventually be replaced or upgraded as sea levels rise.

reliability — How trustworthy a source is — influenced by who produced it, when, using what methods, for what purpose, and whether independent sources corroborate its findings. Even highly reliable sources have limitations.

bias — Systematic distortion in a source caused by the interests, values or purpose of its producer. Bias affects the selection of evidence presented and what is omitted. A biased source can still contain accurate information, but its limitations must be identified and acknowledged.

judgement — A supported conclusion that commits to a clear position after weighing competing evidence. A strong geographical judgement is decisive (not "on the fence"), uses specific evidence to support the conclusion, and explicitly addresses and outweighs the strongest counter-argument.
