UK Landscape & Climate Change Challenge
Landscapes Under Pressure
The UK’s most distinctive landscapes — the Lake District, the Pembrokeshire coast, the Cairngorms, Snowdonia — are not wilderness. They are National Parks: 15 in the UK, covering around 8% of the country, where the public authority must conserve the landscape and ecology while keeping it open for visitors. Pressures are growing on every front. Climate change is shifting weather, vegetation and erosion rates. Flood risk is rising along rivers and coasts. Visitor numbers and second-home demand strain housing and infrastructure. Topic 8 expects you to weigh up these pressures and the management responses.
The UK’s 15 National Parks have two statutory purposes — conserve and enhance natural beauty and wildlife, and promote understanding and enjoyment by the public. Where these conflict, conservation takes priority (the ‘Sandford Principle’).
Conservation vs Development
Park authorities must constantly balance two pressures: keeping the landscape recognisable and supporting the people who live in it. In the Lake District, second-home conversions push average house prices to over 11× local earnings, so young workers leave; planning rules now restrict new homes to local-occupancy in some parishes. In Snowdonia, hydropower schemes generate clean energy but cut tracks across mountainsides, splitting opinion among walkers and conservationists. The Yorkshire Dales has used Environmental Land Management payments to pay farmers to restore peat bogs — a win for carbon storage and flood control, although it changes how some valleys look.
Flood Risk: Rivers & Coasts
Flood risk is rising for two reasons. First, climate change brings more intense rainfall — the UK saw record February 2020 floods after Storms Ciara, Dennis and Jorge dumped 200–300 mm of rain in two weeks. Second, urban growth has paved over fields that used to soak up water. Around 5.7 million UK properties are at flood risk, and the Environment Agency expects this to rise.
Hard engineering uses concrete to hold back water — the Thames Barrier (closed over 220 times since 1982), Boscastle’s harbour wall, sea walls along the Yorkshire and East Anglian coasts. Hard defences work, but they are expensive, age fast and shift the problem along the coast. Soft engineering works with natural processes — tree planting in upper catchments, restoring meanders straightened decades ago, beach nourishment with imported sand, and managed realignment that lets the sea reclaim low-value farmland to absorb storm surges. The Medmerry managed-realignment scheme on the West Sussex coast, finished in 2013, built new flood banks inland and then breached the old shingle sea defence, letting the tide return and creating wetlands that buffer Selsey behind it.
In Pickering, North Yorkshire, the ‘Slowing the Flow’ scheme spent around £3.2 million from 2010 to plant 40,000 trees in upland catchments, build 167 small ‘leaky dams’ from logs and create a flood storage reservoir. The combination slowed run-off so peak river flow into Pickering town centre dropped by an estimated 15–20%. The town flooded in 1999, 2000, 2002 and 2007 — but stayed dry through Storm Desmond in 2015 when neighbouring towns flooded badly. Costs are far lower than concrete defences and the scheme also boosts wildlife and carbon storage.
UK Climate Change — What’s Already Changing
UK climate is already shifting. Met Office records show annual mean temperature rose by about 1.0°C between 1981–2010 and 2014–2023. Summers are getting hotter (July 2022 hit 40.3°C at Coningsby in Lincolnshire — the first time the UK passed 40°C). Winters are warmer and wetter; snowfall in the Cairngorms ski resorts has shortened the season by around 30 days since the 1980s. Sea levels around the UK have risen by around 18 cm since 1900 and continue to rise. Flooding from intense rainfall is now Britain’s most common climate hazard.
Future Uncertainty
How much more change comes depends on global emissions. The Met Office’s UK Climate Projections (UKCP18) sketch out a low-, medium- and high-emissions future. By the 2070s, summers could be 3–5°C hotter under high emissions, and winters 25% wetter. Sea level around London could rise 0.7–1.0 m. But uncertainty is genuine: how the UK’s climate behaves also depends on the position of the jet stream, ocean circulation in the North Atlantic, and on land-use changes that affect how much water soaks in. Predictions narrow as emissions paths become clearer.
National responses focus on mitigation — the legally binding 2050 Net Zero target, offshore wind expansion (the UK now generates over 40% of its electricity from renewables), and the 2030 ban on new petrol and diesel cars. Local adaptation includes installing larger drains, raising flood defences, planting urban trees to cool city centres (London’s ‘Cool Streets’), and grants to households for sustainable drainage. The Climate Change Committee’s 2024 progress report warned the UK is on track to miss its 2030 emissions target, so policy may tighten further in the late 2020s.
Mitigation cuts emissions (UK 2050 Net Zero, >40% renewable electricity); adaptation copes with impacts already happening (Pickering Slowing the Flow, Medmerry managed realignment, urban tree planting). Effective policy needs both at the same time.
