Case studies and evidence

A case requirement describes what you need to study. A place or event is the example you use to meet it.

People, public transport, housing and workshops share a tree-lined street.
Imagined urban setting

These are bounded evidence exercises. They do not replace every dimension of a school’s taught case study.

Slowing the flow at Pickering

Pickering’s catchment project uses measures intended to store water and delay its passage towards the town. Forest Research provides monitoring and an assessment of the Boxing Day 2015 event.

Pickering, North Yorkshire · 2015

Managed realignment at Medmerry

Medmerry moved the defence line inland and allowed an area to become intertidal habitat. The completed scheme was celebrated in November 2013.

West Sussex coast · 2013

Dawlish railway resilience

Winter storms damaged the coastal railway in 2014. Its closure affected connections between the South West and the wider rail network.

Dawlish, Devon · 2014

Amazon forest conversion

NASA’s historical account links forest conversion to agriculture, roads and wider economic incentives. Cattle ranching and commercial crop production create demands for cleared land.

Brazilian Amazon, including Mato Grosso

Forest and plantations in Kalimantan

NASA’s 2012 image account describes forest replacement by palm oil plantations and roads in Kalimantan. A regular plantation pattern differs from irregular natural forest cover.

Kalimantan, Indonesian Borneo

Costa Rica’s forest carbon payments

Costa Rica’s World Bank country page describes payments linked to verified forest emission reductions. This provides a case for evaluating conservation incentives.

Nature-based tourism in Rwanda

The World Bank’s 2023 economic update examines nature-based tourism, jobs and conservation. It also identifies degraded natural assets and limits to expanding particular attractions.

Wolves and ecosystem management in Yellowstone

Wolf reintroduction restored a predator to Yellowstone in the 1990s. National Park Service research examines relationships among wolves, prey, other carnivores and vegetation.

Yellowstone National Park, USA · 1995

Desert springs in Death Valley

Groundwater reaching the surface forms springs that support habitats within a dry landscape. Some pupfish populations occupy only a few springs.

Death Valley National Park, USA

Permafrost thaw and Denali’s park road

Thawing ice-rich ground destabilised a section of Denali’s road. NPS’s 2025 account explains the decision to bridge the active landslide rather than continually repair the slipping road.

Pretty Rocks, Denali National Park, Alaska · 2021

Glacier retreat in Montana

NPS reports that every named glacier in the park became smaller between 1966 and 2015. Repeated imagery and field measurements provide different ways to monitor change.

A 2023 World Bank programme links fiscal management and sustainable development, including improving the BRT operating model with attention to poorer users.

Rio de Janeiro, Brazil

Mumbai’s suburban railway

World Bank documentation identifies the suburban railway as central to Mumbai’s movement of people. Transport upgrades address pressure on an existing system in a growing metropolitan region.
