A recent investigation by the Guardian and its European partners has laid bare a uncomfortable truth about the British countryside: it is disappearing at an alarming rate, with the UK ranking fifth-worst in Europe for the loss of green space to development. For readers of Country Squire Magazine, who cherish the very landscapes now under threat, the findings of this cross-border journalism project make for sobering reading.
The investigation, a collaboration between the Guardian, the Norwegian Institute for Nature Research (NINA), the Arena for Journalism in Europe, and nine other news outlets across eleven countries, used advanced satellite technology to track changes in land use between 2018 and 2023. What it found was a continent-wide erosion of natural habitats, but the situation in the UK was particularly stark. According to the analysis, which employed a deep-learning model developed by NINA to scrutinise high-resolution imagery from the European Space Agency’s Sentinel-2 mission, the United Kingdom lost 604 square kilometres of nature and farmland to concrete and bricks and mortar in just five years. That is an area equivalent in size to the New Forest, swallowed up by development.
The methodology was rigorous and designed to capture losses that official statistics often miss. By using artificial intelligence to detect changes at a much finer scale than previous estimates, the researchers were able to identify not just large-scale infrastructure projects but also the cumulative impact of smaller, piecemeal developments that nibble away at the countryside. The findings were then manually checked by journalists and researchers to ensure accuracy, and the entire methodology and code have been made publicly available for scrutiny. The project’s estimates suggest that Europe as a whole is losing green space at a rate up to one and a half times higher than figures from the European Environment Agency would indicate, with an area the size of Cyprus—some 9,000 square kilometres—turning from green to grey over the study period.
Perhaps most concerning for those who value Britain’s protected landscapes is the revelation that even our most cherished and safeguarded areas are not immune. The investigation found that 12 square kilometres of land within areas designated as national landscapes in England and Wales, formerly known as Areas of Outstanding Natural Beauty, were lost to development. This is equivalent to 1,680 football pitches’ worth of some of the most special natural land in England, Wales and Northern Ireland. The notion that these protections, long considered the gold standard for preserving the beauty of the British countryside, are being quietly eroded will alarm many.
The Guardian team verified almost 250 of the largest developments covering more than 10,000 square metres, which were mainly concentrated in seven national landscapes: the Cotswolds, the Chilterns, the High Weald, the North Wessex Downs, the Kent Downs, Dorset and the Shropshire Hills. The encroachments take many forms, from national infrastructure projects to local housing schemes. One of the most visible is the HS2 rail line, now truncated to run only between London and Birmingham, which cuts a swathe directly through the Chilterns. The satellite imagery captured for this project clearly shows the scale of the incursion into this protected landscape. But HS2 is far from alone. The analysis highlighted numerous housing developments spilling into these beauty spots, including the northward expansion of Poundbury in Dorset, the Lancaster Park development near Hungerford in Berkshire, and a field of new houses to the north-east of Fownhope in Herefordshire. Beyond these larger sites, there are countless smaller encroachments: barn conversions, road widening schemes, and extensions that, cumulatively, take a significant toll on the character of the countryside.
The timing of this investigation is particularly poignant as the government’s new planning bill makes its way through Parliament. The Guardian has recently revealed that this legislation threatens 5,000 of the most protected areas in England, with provisions that would allow developers to pay into a central fund to bypass environmental regulations on particular sites. Many conservationists see this as a significant regression from current environmental protections. Roger Mortlock, chief executive of the countryside charity CPRE, responded to the findings with a sense of dismay. “For a small island we are still struggling with the idea that land is finite,” he said. “It’s shameful to be so near the top of this list when the countryside in this country is so valued – second only to the NHS. It is also so unnecessary when brownfield land, even with planning permission, remains unused. We should rethink our towns and cities as compact sustainable places that celebrate the countryside on their doorstep. Instead land-hungry, car-dependent, identikit, unaffordable housing estates without proper infrastructure are taking green fields that could deliver the food we eat, power nature’s recovery and climate solutions.”
His point about brownfield land is a crucial one. Recent research has indicated that there are enough previously developed sites in England to accommodate almost all of the 1.5 million homes the government aims to build by the end of this Parliament. The fact that developers continue to target green fields and protected landscapes, rather than these derelict urban sites, suggests a systemic failure in planning priorities.
The drivers of this loss are not unique to Britain. Across Europe, the investigation found that housing and road construction accounted for a quarter of all cases of green space conversion. But the development of luxury tourism resorts and industrial projects also played a significant role in consuming natural land. For the UK, the ranking of fifth-worst in Europe relative to geographic size places us alongside nations where development pressure on the landscape is most intense.
For those who live in or visit the Cotswolds, the Chilterns, or the Shropshire Hills, these findings will not come as a complete surprise. The slow creep of development is something that can be observed from year to year, field by field, lane by lane. What this investigation provides is the hard data to confirm those observations, and a stark warning that the special protections we thought were in place are not holding. As the next phase of this project expands to monitor nature loss on a global scale, with a crowdsourced citizen science initiative inviting the public to participate, the message from this European study is clear: our green spaces are under pressure as never before, and it is going to take vigilance, robust data, and political will to ensure that what remains of our natural heritage is not lost forever.
