KISKUNMAJSA – On his land in the Great Hungarian Plain, Oszkár Nagyapáti descended into a sandy pit, digging with his hands in search of groundwater that seems to be vanishing at an alarming rate.

“It’s far worse than before and deteriorating every year,” he lamented as a murky trickle finally surfaced in the hole. “Where has all the water gone? It’s hard to believe.”

Nagyapáti has observed with increasing concern as this southern Hungarian region, historically a rich agricultural hub, turns progressively arid. Where once verdant crops and grasses flourished, the landscape is now marked by deep soil fissures and burgeoning sand dunes, evoking images more akin to the Sahara than Central Europe.

Semiarid Conditions

Known as the Homokhátság, this area is now often classified in studies as semiarid—a climate classification typically associated with parts of Africa, the Southwestern United States, or the Australian Outback. The region is experiencing scant rainfall, drying wells, and a groundwater level that continues to sink ever deeper.

In a 2017 paper in European Countryside, a scientific journal, researchers cited “the combined effect of climatic changes, improper land use and inappropriate environmental management” as causes for the Homokhátság’s aridification, a phenomenon the paper called unique in this part of the continent.

Fields that in previous centuries would be regularly flooded by the Danube and Tisza Rivers have, through a combination of climate change-related droughts and poor water retention practices, become nearly unsuitable for crops and wildlife.

‘Water guardians’

Now a group of farmers and other volunteers, led by Nagyapáti, are trying to save the region and their lands from total desiccation using a resource for which Hungary is famous: thermal water.

“I was thinking about what could be done, how could we bring the water back or somehow create water in the landscape,” Nagyapáti told The Associated Press. “There was a point when I felt that enough is enough. We really have to put an end to this. And that’s where we started our project to flood some areas to keep the water in the plain.”

Along with the group of volunteer “water guardians,” Nagyapáti began negotiating with authorities and a local thermal spa last year, hoping to redirect the spa’s overflow water — which would usually pour unused into a canal — onto their lands. The thermal water is drawn from very deep underground.

Mimicking natural flooding

According to the water guardians’ plan, the water, cooled and purified, would be used to flood a 2½-hectare (6-acre) low-lying field — a way of mimicking the natural cycle of flooding that channelizing the rivers had ended.

“When the flooding is complete and the water recedes, there will be 2½ hectares of water surface in this area,” Nagyapáti said. “This will be quite a shocking sight in our dry region.”

A 2024 study by Hungary’s Eötvös Loránd University showed that unusually dry layers of surface-level air in the region had prevented any arriving storm fronts from producing precipitation. Instead, the fronts would pass through without rain, and result in high winds that dried out the topsoil even further.

Creation of a microclimate

The water guardians hoped that by artificially flooding certain areas, they wouldn’t only raise the groundwater level but also create a microclimate through surface evaporation that could increase humidity, reduce temperatures and dust and have a positive impact on nearby vegetation.

Tamás Tóth, a meteorologist in Hungary, said that because of the potential impact such wetlands can have on the surrounding climate, water retention “is simply the key issue in the coming years and for generations to come, because climate change does not seem to stop.”

“The atmosphere continues to warm up, and with it the distribution of precipitation, both seasonal and annual, has become very hectic, and is expected to become even more hectic in the future,” he said.

‘Immense happiness’

Following another hot, dry summer this year, the water guardians blocked a series of sluices along a canal, and the repurposed water from the spa began slowly gathering in the low-lying field.

After a couple of months, the field had nearly been filled. Standing beside the area in early December, Nagyapáti said that the shallow marsh that had formed “may seem very small to look at it, but it brings us immense happiness here in the desert.”

He said the added water will have a “huge impact” within a roughly 4-kilometer (2½-mile) radius, “not only on the vegetation, but also on the water balance of the soil. We hope that the groundwater level will also rise.”

Drought task force

Persistent droughts in the Great Hungarian Plain have threatened desertification, a process where vegetation recedes because of high heat and low rainfall. Weather-damaged crops have dealt significant blows to the country’s overall gross domestic product, prompting Prime Minister Viktor Orbán to announce this year the creation of a “drought task force” to deal with the problem.

After the water guardians’ first attempt to mitigate the growing problem in their area, they said they experienced noticeable improvements in the groundwater level, as well as an increase of flora and fauna near the flood site.

The group, which has grown to more than 30 volunteers, would like to expand the project to include another flooded field, and hopes their efforts could inspire similar action by others to conserve the most precious resource.

“This initiative can serve as an example for everyone, we need more and more efforts like this,” Nagyapáti said. “We retained water from the spa, but retaining any kind of water, whether in a village or a town, is a tremendous opportunity for water replenishment.”
