Natural vs Human-Modified Landscapes
A natural landscape is an area shaped mainly by natural processes with little human influence, while a human-modified (cultural) landscape is one that people have changed by farming, building, mining, drainage, damming or other activities. In brief: truly untouched landscapes are now rare, and most of Earth’s land shows some human influence, so geographers think of a spectrum from wilderness to fully built environments. Landscape change can be fast (a new dam or a city) or slow (terracing, grazing), and it has effects on soils, water, wildlife and climate. Understanding the change helps in managing land sustainably.
Landscapes are the visible face of the interaction between people and the environment. This guide defines natural and human-modified landscapes, describes the main kinds of human change and its causes, compares the two in a table, works through a land-cover change calculation, outlines the history of landscape change and corrects common mistakes.
What is a landscape?
A landscape is the visible features of an area of land, including its landforms, water, vegetation and the structures built by people, together with the way people see and use it. Physical geographers study landscapes as products of geology, climate and ecological processes; human geographers study them as products of culture, economy and history. The landscape of a place can be read like a record: field patterns, terraces, roads and buildings show how people have used the land over time.
What are natural landscapes?
Natural landscapes are shaped by natural processes: tectonics, erosion, climate and ecological succession. Examples are polar ice caps, rainforest, desert dunes, high mountains and wild coasts. Strictly, few areas are completely free of human influence, because pollution, climate change and introduced species reach almost everywhere. For this reason, the term “wilderness” is used for large areas with little human impact, and the term “semi-natural” for areas such as heathland and wetlands that are partly maintained by traditional use. Protected areas, such as national parks, try to conserve natural landscapes, which are valued for biodiversity, water supply, carbon storage and recreation.
What are human-modified landscapes?
Human-modified landscapes (cultural landscapes) include:
- Agricultural landscapes: fields, hedgerows, orchards and terraces, such as rice terraces on steep slopes in Asia and vineyards in Europe.
- Urban and industrial landscapes: cities, roads, ports, factories and airports, with surfaces sealed by concrete and asphalt.
- Engineered water landscapes: dams and reservoirs, canals, irrigation systems, drained wetlands and land reclaimed from the sea (polders in the Netherlands, about one-sixth of which is reclaimed land).
- Extractive landscapes: quarries, open-pit mines, spoil heaps and oil fields.
- Managed forests and parks: plantations and designed gardens.
These changes alter the surface, soils, drainage and habitats, and they often bring benefits (food, energy, homes, flood protection) and costs (habitat loss, erosion, pollution, subsidence).
What causes landscape change?
Natural causes include earthquakes, volcanic eruptions, floods, landslides, fires, coastal erosion and slow climate change. Human causes include population growth, urbanization, agriculture, deforestation, mining, infrastructure, tourism and climate change from greenhouse gas emissions. Changes may be reversible (a field returning to forest after abandonment) or irreversible (a built-up area or a drained peat bog). Landscape change is studied using maps, aerial photographs, satellite images and field surveys, comparing the same area at different dates, and expressed as the area or percentage of each land cover that has changed. Managing landscape change involves planning, protection of valuable areas, restoration of damaged land (reforestation, rewetting of wetlands) and sustainable land use.
Natural and human-modified landscapes compared
| Feature | Natural landscape | Human-modified landscape |
|---|---|---|
| Main shaping forces | Tectonics, erosion, climate, ecology | Farming, building, mining, engineering |
| Vegetation | Native, self-sustaining | Crops, plantations, lawns, sparse |
| Surface | Soil, rock, water, ice | Fields, concrete, asphalt, reservoirs |
| Biodiversity | Usually higher | Usually lower, with exceptions |
| Examples | Rainforest, tundra, desert | Terraces, cities, polders, mines |
Worked example: measuring land-cover change
- Data (hypothetical): a study area of 1,000 ha (hectares) had 800 ha of forest in 1995 and 520 ha in 2025; the rest has been converted to farmland and settlement.
- Area lost: 800 − 520 = 280 ha.
- Percentage change: 280 ÷ 800 × 100 = 35 percent of the original forest has been lost.
- Annual rate: over 30 years, 280 ÷ 30 = 9.3 ha lost per year on average.
- Share of the study area: forest cover fell from 800 ÷ 1,000 = 80 percent to 520 ÷ 1,000 = 52 percent of the area, which is a drop of 28 percentage points. Percentage points (28) and percent change (35 percent) are different measures.
- Projection: if the loss continued at 9.3 ha a year, the remaining 520 ha would be gone in 520 ÷ 9.3 = about 56 years (a linear projection; real rates change).
How has human influence on landscapes grown?
People have modified landscapes since early hunters used fire to manage vegetation. The development of agriculture, from about 10,000 years ago, created fields, irrigation and terracing, and the earliest cities appeared in the following millennia. The Banaue Rice Terraces in the Philippines and the terraces of the Andes are examples of long-standing engineering. The Industrial Revolution from the 18th century brought mines, factories and rapid urban growth, and the 20th century saw large dams, motorways and the expansion of megacities. Some scientists use the term “Anthropocene” for the present period when human activity is a major force shaping Earth’s surface, although it is not an officially recognized geological epoch.
Which mistakes are common?
Mistake 1: Thinking that natural landscapes are untouched by people
Many “natural” areas have been managed for thousands of years, and global effects such as climate change reach all of them.
Mistake 2: Assuming that human modification is always harmful
It may have benefits, such as terraces that prevent erosion, and traditional managed landscapes often have high biodiversity.
Mistake 3: Mixing up percentage change and percentage points
A fall from 80 to 52 percent of the area is a drop of 28 percentage points, but a 35 percent loss of the original forest.
Mistake 4: Assuming that landscape change is always slow
Dams, mines, floods and landslides can change a landscape in days or years, not only over centuries.
