Why has Britain's grass turned yellow? A plant scientist explains what happens next

Across Europe, fields, parks, and lawns have turned yellow due to extreme drought conditions, revealing ancient underground structures that retain water. July 2023 was the driest month ever recorded in England and Wales, marking the fourth consecutive year of drought impacts. Grasses, while resilient to dry conditions, face challenges in maintaining the lush green landscapes Britain is known for. Scientists note that grasses have existed for over 55 million years and thrive in arid environments, yet the specific grasses used in British lawns are less adapted to prolonged dry spells. During severe droughts, these grasses conserve water by shutting down and protecting their growth centers, allowing recovery after rainfall. However, repeated droughts raise concerns about the sustainability of traditional lawn maintenance practices in the UK.

England is enduring its most severe drought in recent history, with nearly three-quarters of the country, 71.3 percent, officially classified as being in drought conditions. The situation has escalated rapidly, impacting up to 45 million people and threatening food security, ecosystems, and local economies. The National Drought Group has confirmed that the East Midlands, Lincolnshire, Northamptonshire, Kent, East Sussex, Solent, and the South Downs have joined regions already in drought, while the North East and Yorkshire are under a “prolonged dry weather” status. These conditions follow the driest July on record for southern England, with just 1.9 millimeters of rainfall, compared to the usual 6.5 millimeters. This marks the second consecutive summer drought and the third in four years, following the severe drought of 2022. The effects of the drought are evident across the landscape. Reservoirs and rivers are shrinking, exposing riverbeds and reducing water availability for both human consumption and agriculture. Agricultural land, forests, and fields have turned brown, with farmers reporting significantly lower yields. Livestock farmers are forced to use winter feed due to insufficient grass growth, while others struggle to maintain irrigation for crops. The National Farmers’ Union (NFU) has raised concerns about potential food shortages, citing the combined impact of repeated heatwaves, drought, and previous winter flooding. Tom Bradshaw, the NFU’s president, warned that the country could face food insecurity as global food-producing nations also experience similar climatic challenges. The heatwave has intensified, with temperatures projected to reach 38 degrees Celsius this week. The UK Health Security Agency has issued amber heat health alerts across the country, urging residents to stay hydrated and avoid prolonged exposure to the sun. Meanwhile, the Met Office has issued a rare amber extreme heat warning, covering much of the Midlands, London, parts of the southeast, Yorkshire, and the east of England. Jason Kelly, the Met Office’s chief forecaster, explained that high-pressure systems are driving the heat, with temperatures expected to peak on Thursday. He noted that southerly and southeasterly winds are drawing in hot air from mainland Europe, contributing to the prolonged heatwave. The drought has also disrupted agricultural practices, forcing some farmers to abandon certain crops. On Jeremy Clarkson’s Diddly Squat Farm, 200 acres were left uncropped this year to prevent financial loss, highlighting the economic strain on rural communities. The situation has prompted calls for policy changes, including the expansion of on-farm reservoirs and flexible abstraction licenses that would allow farmers to store water during rainy periods. Helen Wakeham, director of water at the Environment Agency and chair of the National Drought Group, emphasized the urgency of the crisis, stating that water usage is outpacing natural replenishment. She warned that the consequences of the drought will extend beyond environmental degradation, affecting wildlife, the economy, and public health. The broader implications of the drought are beginning to ripple through the food supply chain. With 27 million people subject to water restrictions, the strain on agricultural resources is intensifying. The National Farmers’ Union has urged the government to implement a risk register for vulnerable businesses and improve abstraction licensing processes to better manage water distribution. Long-term strategies include investing in reservoirs, expanding the Water Management Grant program, and promoting climate-adaptive farming techniques. Alistair Carmichael, chair of the House of Commons’ Environment, Food and Rural Affairs Committee, warned that the effects of this summer’s extreme weather will be felt within six to 12 months, with reduced yields in key crops like barley and wheat. He cautioned that increased reliance on imported food may not provide relief, as European countries also grapple with similar conditions. Supermarkets and consumers are already feeling the impact of the drought. Produce such as potatoes, broccoli, and lettuce is becoming scarcer, with some items being imported from abroad. Prices are expected to rise further, driven by both domestic and international factors. Christian Jaccarini, a senior economist at the Energy and Climate Intelligence Unit, noted that global food prices are already 40 percent higher than pre-2021 levels, and the current heatwaves could push them even higher. A forthcoming survey by the British Standards Institution indicates that 46 percent of UK businesses, including food and beverage suppliers, anticipate price increases in the coming months. Fresh produce, in particular, is likely to be affected first, with some retailers advising customers to consider alternatives to expensive, low-quality products. The crisis has sparked urgent discussions about the sustainability of the UK’s food system. Environmental advocates argue that the current model of intensive farming, reliant on chemical inputs and unsustainable water use, is ill-equipped to handle the escalating climate challenges. Solutions proposed range from restoring soil health through regenerative farming practices to implementing stricter regulations on water usage. Farmers and environmentalists alike agree that immediate action is necessary to prevent further ecological and economic damage. While short-term measures such as banning disposable barbecues aim to reduce wildfire risks, long-term reforms are essential to ensure food security and environmental resilience in the face of an increasingly unpredictable climate.

I’m a plant scientist. Here’s why Britain’s grass has turned yellow

Across Europe, including Britain, fields, parks, and lawns have turned yellow due to severe summer droughts, with July 2023 being the driest month ever recorded in England and Wales. This trend reflects broader concerns about the impact of climate change, as heatwaves become more frequent. Grasses, while resilient, face challenges in adapting to prolonged dry conditions. British lawns, composed of grasses typically suited to damp climates, struggle under current drought conditions. However, these grasses have survival mechanisms, such as conserving water and prioritizing growth in protected areas. The phenomenon highlights the vulnerability of landscapes valued for their greenery amid changing environmental conditions.

Remains of lost village uncovered as drought lowers reservoir levels in record-breaking heatwave

The remains of a lost village, Nether Hambleton, have been exposed due to record-breaking drought and extreme heatwave conditions in England. The village was flooded in the 1970s to create Rutland Water reservoir, one of Europe's largest man-made lakes. Exceptionally low water levels in the reservoir, which dropped by 16% in July, marking the biggest reduction in at least 30 years, have revealed stonework and building foundations. The drought affects around 71.3% of England, classified as a 'flash drought' due to low rainfall and high temperatures. The situation is exacerbated by the fifth heatwave of the year, with forecasts indicating insufficient rainfall to restore water levels soon.

Lost village revealed as drought lowers water levels

A lost village called Nether Hambleton has been revealed due to low water levels at the Rutland Water reservoir, which was created by flooding the area in the 1970s. The reservoir, one of the largest man-made bodies of water in western Europe, submerged over 3,000 acres of land, including buildings, farms, and farmhouses. As England faces severe drought conditions, with the East Midlands entering drought status, water levels have dropped enough to expose remnants of the village. The drought has led to an amber heat warning, with temperatures expected to reach up to 38°C. Officials warn that the drought is worsening and urge residents to conserve water to support agriculture and ecosystems.
