What changed, and what do people perceive to have changed? Land use transformations in peninsular Spain over the past 50 years
This study reveals a growing divergence between documented land-use transformations and public perceptions in peninsular Spain over the past 50 years, where highly visible changes like urbanization are recognized while significant shifts in agriculture and forestry are increasingly overlooked, highlighting the need to integrate social perceptions into land-management policies.

The landscape around us is never truly still. Over the last century, the Earth's surface has been reshaped by human hands at a pace and scale never seen before. Forests are cleared for farms, fields are paved for cities, and rivers are diverted to water crops. Scientists call these shifts "land-use transformations." While maps and satellite images can measure exactly how much ground has changed, there is another layer to the story: how people actually see those changes. Our memories and daily experiences shape what we notice, and sometimes what we notice does not match the reality on the ground. This gap matters because if the public does not recognize a change, they may not support the policies needed to manage it. Understanding the difference between what is happening to the land and what people think is happening is essential for planning a future that works for both nature and society.
In a recent study focused on peninsular Spain, researchers set out to bridge this gap. They wanted to know if the people living there could accurately sense the massive shifts occurring in their environment over the last fifty years. To do this, the team combined hard data with human stories. They gathered official records, satellite maps, and census figures to track eight specific types of land changes, such as the spread of cities, the expansion of forests, the growth of renewable energy farms, and the intensification of agriculture. They then asked 2,071 people across the country a simple question: did you notice these changes happening in your local area during specific decades, from the 1960s through to the 2020s? The goal was to see if the public's perception matched the documented reality.
The results revealed a complex picture where what people see depends heavily on what is happening and when it happened. Overall, just over half of the respondents said they had noticed changes in their landscape. The researchers found a clear link: when a change was intense and widespread, people were more likely to notice it. However, this connection was not perfect, and it has weakened over time. The most visible changes, such as the rapid growth of cities, the construction of wind and solar farms, and the scars left by wildfires, were consistently recognized by the public. These events leave a strong visual mark on the land, making them hard to ignore. For instance, the boom in urban development during the 1990s and 2000s was widely remembered, and the increasing frequency of fires in recent years has kept the issue in the public eye.
In contrast, other major transformations went largely unnoticed, even though they were reshaping the territory just as significantly. The study showed that people struggled to perceive the intensification of farming, the expansion of irrigation systems, and the planting of new forests. These processes often happen gradually or spread out across the countryside, blending into the background of daily life. A farmer might switch to more efficient equipment or a field might slowly turn into a grove of trees, but these shifts do not create the sudden, dramatic visual disruption of a new highway or a burned forest. Consequently, the public often normalizes these changes, accepting them as part of the natural evolution of the land rather than recognizing them as active, powerful forces of transformation.
The age of the person asked also played a role, but not in the way one might expect. The study found that older and younger people generally agreed on what they saw; the main differences were not about age, but about the specific type of change and the time period. Interestingly, the youngest group, those between 18 and 24, were the only ones who continued to see urbanization as a growing trend, even as the construction boom had actually slowed down. This suggests that for younger people, the issue of housing and land use remains a pressing, visible concern, whereas older generations may remember the peak of the building boom as a past event.
Perhaps the most striking finding was the growing disconnect between reality and perception in recent decades. While the land has continued to change, the public's ability to detect those changes has become less sensitive. This phenomenon, known as shifting baselines, means that as the environment changes, our standard for what is "normal" shifts with it. A landscape that looks different today might not feel different to someone who has grown up with it. The researchers concluded that highly visible changes like urbanization and renewable energy infrastructure are easily recognized, but the quieter, slower processes like agricultural modernization and forest growth are slipping under the radar. This is a critical insight for policymakers. If society does not perceive a gradual change as a problem, it will not demand action to address it. To manage the land effectively, planners must look beyond what is immediately obvious to the eye and consider the slow, steady transformations that are quietly rewriting the map of the country.
